Description

Vehicle with air duct, bellows and use of a bellows

The invention relates to a vehicle, in particular rail vehicle with an air guide, a bellows, and the use of a bellows according to the preambles of the independent claims.

It is known in vehicles, especially rail vehicles, that the design and arrangement of drive and Hilfsskompo ^¬ nents, in particular ventilation systems are optimized so that the passenger compartment is maximized in the vehicle.

From WO 2008/006679 A2, for example, a cooling air supply for a rail vehicle for cooling components in the underfloor area is known. The cooling air source is arranged ^¬ in the roof area. The cooling air arrangement further includes a plurality of fans and an air duct, which leads in the middle of the rail vehicle from the roof area in the underfloor area. The cooling arrangement serves to ventilate the components in the underfloor area.

From US 4 241 666 an air supply for traction engines is known. The air cooling system includes an air intake duct on the front side, outside the rail vehicle car. This air inlet channel runs along the face of the rail running ^¬ tool in the underfloor area where the air channel leads to the cooling air supply to the traction motors.

A disadvantage of the known vehicles is that the air supply requires additional components, in particular air ducts, which require additional space in or directly around the vehicle. This space is not present in the area of the bogie of low-floor rail vehicles, since components in the Area of the bogie, such as air bags and the passenger crossing the passage of air ducts along the front side and in particular the passage of these air ducts in the underfloor area impossible.

It is the object of the present invention to provide a vehicle, in particular a rail vehicle, which avoids the after ^¬ parts of the prior art and in particular eliminates the use of an additional air duct in the passenger compartment or on the front side of the car. The object is achieved by a vehicle, in particular a rail vehicle with an air guide and by a bellows to form a transition between two cars and by the use of a bellows as an air guide according to the independent claims.

According to the invention, the vehicle comprises at least a first car and a second car. The first car and the second car each include a car body. According to a first aspect of the invention, an air supply, in particular cooling air duct is provided, with which a place to be ventilated, in particular to be cooled location, in an underfloor area of the first carriage and / or the second carriage air, in particular cooling air from egg ^¬ ner air source, in particular one Cooling air source, in a roof area of the first car, can be fed. According to the invention runs the air duct at least partially in the region Zvi ^¬ rule the first carriage and the second carriage outside of the passenger compartment. The air source is preferably a ventilation system, in particular a ventilation fan. In the roof area comprises an arrangement of the air source on the roof, that is outside the car body, and a Anord ^¬ tion of the air source in the car body near the roof, for example, in a space between the roof of the car body and a ceiling of the passenger compartment.

In one embodiment, the air duct extends in the area between the first car and the second car outside the car body.

Thus, the air duct does not run within the passenger ^¬ space. As a result, the passenger compartment can be maximized.

The passable by passengers transition between the first Wa gene and the second car counts above and below as part of the passenger compartment.

Compressed air for pneumatic systems is not included within the meaning of this publication ^¬ dung from the concept of air.

According to the invention, the air duct in a vehicle, in particular a low-floor ^rail vehicle from an air source ^¬ , in particular a ventilation fan, in the roof of the first car to components, especially drive motors inverter or other components, lead in the underfloor area of the first car and / or the second car ,

Thus, the air duct allows the use of an air source in the roof area for the ventilation of the components in the underfloor area of the first car as well as the second car.

In another embodiment, both the first and second carriages include an air source. The air duct can be used to guide air from a cooling air system, fresh air system or air from a combination of these systems. The air can be used in particular for cooling traction motors and / or for the combustion process of the o- of the internal combustion engines, in particular diesel engines serve.

Thus, by means of the air guide, an underfloor region, in particular components in the underfloor region, in particular drive components and energy supply components of the vehicle, can be supplied with air from an air source mounted in the roof region of the first wagon.

Drive components are for the purposes of this application, for example, drive motors, drive converter. For the purposes of this application, power supply components are, for example, transformers, mains filters and auxiliary converters and / or internal combustion engines.

In a preferred embodiment, at least the first carriage has at least one driven bogie, in particular a Jacob bogie with at least one drive motor. Air can be supplied to the air source with the air duct. The air guide thus enables the supply of components, in particular the drive motors of the driven bogie with air from an air source in the roof area.

In a preferred embodiment, the rail vehicle is a low-floor rail vehicle and the location to be ventilated one or more components, in particular drive motors in the underfloor area. In a preferred embodiment, the air guide runs along the front side of the first car and / or second car along.

The course of the air duct along the front side of the carriage allows easy attachment of the air duct on the front side. This makes it possible to easily guide the air from the roof area into the underfloor area of the rail vehicle.

In one embodiment, the air duct has a channel. The channel is mounted on the front side of the first car and / or second car.

Thus, the air duct is guided along the car body and can be easily attached to this. The car end wall can be used as a side of the channel, making the channel easier and cheaper to run.

In one embodiment, a part of the air duct as a channel, which surrounds substantially the entire opening on the front side of the carriage and is chosen in its masses so that there ^¬ ran the bellows can be attached formed. The bellows ^¬ tenbalg is not mounted directly on the front side of the car but on the channel in this case. As a result, with the same vehicle spacing, the distance which must be bridged by the bellows is smaller. The bellows can be shortened. The bellows can be shortened, for example, by one fold. In a preferred embodiment, the air guide is at least partially by a transition, which limits a passenger crossing, in particular a bellows, in particular a double-walled or multi-walled bellows, formed between the first carriage and the second carriage.

Thus, a part of the air duct may be formed by the anyway required transition between the first carriage and the second carriage. This eliminates the expense of an additional air duct at least partially. The vehicle can be built so ^{kostengüns ¬} tiger. Advantageously, it also proves that the air duct claimed so less additional space between the first car and the second car.

In particular, when cornering, it is advantageous, in addition to the connection, which limits a passenger crossing as possible no other components to have attached to the front of the first and / or second car, as move in cornering, the two end faces against each other. The components can thus touch each other while cornering and thereby damage.

In one embodiment, one or more folds of the bellows are used to guide the air. The air flow along a bellows is particularly simple because the bellows already forms a kind of partial air ^¬ channel through its folds.

In a particularly preferred embodiment, the Luftfüh- tion is at least partially by the transition and a further Be ^¬ limitation, in particular a sub-channel formed. The transition, in particular bellows is extended by an adjoining this transition sub-channel to an air duct. As a result, the air flow can be carried out with little effort. Instead of a channel only a partial channel is needed because the transition, in particular the bellows complements the channel.

In one embodiment, the sub-channel is made of the same material as the bellows. In one embodiment, the sub-channel is attached to the end face of the first carriage or the second carriage so that it forms an air channel with the transition, in particular a fold of the bellows. In one embodiment, the sub-channel is attached directly to the transition, in particular to the bellows.

In a particularly preferred embodiment, the bellows is designed as a double-walled or multi-walled bellows. The bellows thus has an inner wall and an outer wall. Between the inner wall and the outer wall, a space forms Zvi ^¬ rule. The air duct is at least partially formed in the intermediate space. In particular, this part of the air guide is formed by the entirety of the intermediate space which is formed by the inner wall and the outer wall.

A double-walled bellows is a bellows that consists of two bellows and thus has an inner bellows, which surrounds the passenger transition and has an outer bellows, which surrounds the inner bellows. The inner bellows so forms the inner wall of the double folds ^¬ bellows and the outer bellows, the outer wall of the bellows doppelwandi ^¬ gen. Bellows are designed to protect against noise and to improve the thermal insulation often double-walled. The guidance of the air in the space thus makes the use of an air duct between the first car and the second car superfluous.

A multi-walled bellows may for example have a further, that is a third wall. The third wall in turn forms itself a bellows, which surrounds the other two bellows (first wall and second wall). A multi-wall Fal ^¬ tenbalg is still heat and sound insulating as a double--walled bellows. Further embodiments of multi-walled bellows are conceivable.

Between the inner wall and outer wall of the bellows forms a gap. This space is used directly as an air duct for guiding air. In one embodiment, the gap by means incorporated in the space between partition walls into a plurality of spaces is divided among ^¬.

Thus, the air flow is adaptable to the conditions of the vehicle. In particular, so can the double-walled bellows by a partition extending in the direction of travel, which is arranged at the top in the Faltenbalgmitte and a partition in

Direction running, which is arranged at the bottom of the bellows center, divide the Faltenbalgzwischenraum in a left and in a right sub-channel. Further subdivisions of the intermediate space of the bellows are conceivable. As a result, no further components need to be arranged in the region between the first carriage and the second carriage. By using the bellows as an air duct, a moving with the car, flexible air duct is created.

Regarding the first aspect of the invention, especially in the case of a low-floor rail vehicle with driven Drehge ^¬ stell, especially Jakobsdrehgestell the space between the car and especially in the bogie when driving through tight bends are so narrow that air ducts for guiding air from the roof area in the Underfloor area outside of the bellows in modern transitions with a generous cross section practically impossible. The channel guidance inside the car is undesirable, since so passenger compartment is claimed. Through the air duct in the double-walled bellows, a guide of air from the roof area is made possible in the underfloor area, which manages without channels in the car interior and thus takes up no space in the car interior. In particular, in the case of a rail vehicle with Jakobsdrehge ^¬ stell formed in the bellows air duct allows easy guidance of the air in the underfloor area, in particular to the traction motors of the Jacob bogie, as the bellows is mounted directly on the Jacob bogie.

Advantageously, it turns out that are guided at a very narrow space conditions ^¬ nits between the cars, particularly in the area of the bogie of a low-floor rail vehicle, air, in particular cooling air and / or combustion air into the underfloor region, in particular the traction motors and / or combustion engine of the vehicle can, without cooling air channels inside the car are needed. The gap between the inner wall and the outer wall of the bellows, in particular the entirety of the gap, wel ^¬ cher is formed by the inner wall and the outer wall, bie ^¬ tet a relatively large air duct cross-section, resulting in low air velocities with correspondingly low flow pressure losses and low noise result.

In a preferred embodiment, the air guide at least one upper connecting portion for connecting the

Air duct on the air source and / or at least one unte ^¬ ren connecting portion for connecting the air duct in the underfloor area. By the upper connecting portion, the part of the air duct, which is located between the first car and the second car, can be easily connected to the settled in the roof area air source, for example with a ventilation fan.

Through the lower connecting portion of the part of the air duct, which is located between the first car and the second car can be easily in the underfloor area of

Rail vehicle connect.

In a preferred embodiment, the upper and / or the lower coupling portion is not part of the transition Zvi ^¬ rule the first carriage and the second carriage. In other words, the upper and / or lower connecting portion is formed as an independent section, which is attachable to the air duct, in particular to the transition. This allows a modular design of the air duct. Depending on the air source to be connected and the circumstances of the vehicle, the upper connecting section can be adapted. Depending on the location to be cooled and the conditions of the vehicle, the lower connecting section can be adapted to the ^¬ . For the remaining air flow, especially for the transition, especially for the double-walled bellows, so a universally applicable design can be used. In one embodiment, the upper and / or lower connecting portion is designed as a channel, which surrounds substantially the entire opening at the end face of the carriage and is selected in its masses so that the bellows can be attached thereto. The bellows is not attached directly to the end face of the car but to the channel in this embodiment. The channel contains openings, which lead in the assembled state in the gap of the bellows.

As a result, with the same vehicle distance, the distance which must be bridged by the bellows smaller. The bellows can be shortened. The bellows can be shortened, for example, by one fold. Further, the openings of the channel allow easy passage of air from the duct into the Fal ^¬ tenbalg or from the bellows into the channel.

In a preferred embodiment, the upper connecting portion and / or the lower connecting ^portion extends in the Wa ^¬ gene. The upper connecting portion and / or the lower connec ^¬ tion section exits the front side of the first car and / or the second car, in particular, the upper and / or. or open directly under the connecting portion in the intermediate space of the double-walled bellows. The end-side exit of the upper connecting portion and / or the lower connecting portion thus allows a particularly easy ^¬ connection of these connecting portions with the part of the air duct, which is located between the first car and the second car.

In one embodiment, the upper connecting portion is formed by an air duct in the roof area of the first car. The air duct leads in the roof area from the air source to the front side of the first car and ends there in an opening.

The arrangement of the upper connecting portion in Dachbe ^¬ rich a simple connection of the air source is made possible with the air ^¬ management.

In one embodiment, the lower connecting portion is formed by an air duct in the bottom area of the first car. The air duct leads in the bottom area of an opening in the front side of the first car in the underfloor area, in particular to the drive motors of the first car. In the use ^¬ state, the opening is preferably in the space of the double-walled bellows.

The arrangement of the lower connection section in the floor area enables a simple connection of the air duct to the underfloor area.

In a preferred embodiment, the upper connecting portion and / or the lower connecting portion is at least partially formed as a hose. The upper Verbindungsab ^¬ section is connectable to the air source. The lower connec ^¬ tion section is connected to the underfloor area, in particular the drive motor. Hose is to be understood broadly in the sense of the application. In a preferred embodiment, the hose is a flexible, movable channel which is formed by a fabric, in particular fabric-like material. Particularly preferred is a channel made of the same material as the bellows. Particularly preferred who ^¬ the materials used in the production of transitions, in particular bellows. The shape of the tube is irrelevant. The hose can be configured, for example, round or square. The hose is elastic in a preferred embodiment.

By using a hose for at least part of the upper and / or lower connecting portion of the connecting portion is particularly simple, inexpensive and flexible. In particular, such a Verbindungsab ^{¬ section} allows the connection of the relative to each other moving carriage and transition, in particular bellows. The air duct is such an independent unit. This allowed ^¬ light the use of the air duct in vehicles without air duct in the roof area and / or the underfloor area.

Due to the design of the lower and / or upper connecting section as a hose, this connecting section takes up no space in the vehicle body. This provides more space for other components.

By the execution of the lower and / or upper connecting portion of a tube of this connecting portion particular ^¬ DERS flexible. The hose allows easy guidance of the air duct along other components. In one embodiment, the lower and / or upper connecting portion is designed as a further bellows.

A second aspect of the invention relates to the routing of air, in particular air-conditioning air from an air source, in particular ^¬ sondere an air conditioner of the first carriage to the second carriage.

According to the invention according to the second aspect of the invention comprises a vehicle, in particular rail vehicle, a first car and at least one second car. The first car and the second car each include a car body. An air duct, in particular for air conditioning air, is provided with wel ^¬ cher air from the first car body in the second car body is conductive. The air through the air duct is at least partially ^¬ by a double-walled or multi-walled bellows (26) between the first car body and the second car body can be conducted. The double-walled bellows has an inner wall (28) and an outer wall (30). Between the inner wall (28) and the outer wall (30) forms a gap. Erfindungsge ^¬ Mäss is the totality of the space as an air conduction ver ^¬ reversible.

In the sense of the application "entirety of the gap closes, is what is formed by the inner wall and the outer wall of the double folds ^¬ bellows forming a channel by zusätzli ^¬ che boundaries in the space between the inner wall and the outer wall of the bellows from. The air duct in the bellows is completely formed in this sense by the inner wall and outer wall of the bellows, without further, in the intermediate space ^¬ brought channel boundaries are present. The intermediate space of the bellows is additionally limited only by the frontal limited car body walls and thus forms in its entirety ^{¬ unit} an air duct.

In the second aspect of the invention, the air guide to the Guide of air of an air conditioning plant can, a Frischluftanla ^¬ ge, a heating system or a combination of these systems are used.

Thus, the need for a separate air source in the second car can be omitted, since the air of the air source of the first car can be passed through the air duct in the second car.

In addition to the first carriage and the second carriage, further carriages may be connected to a correspondingly formed transition. This allows the use of an air source for a variety of cars.

In one embodiment, in the first car body, in particular in the roof area, an air source, in particular an air conditioning system, attachable. The air source can be connected to the air duct.

The arrangement of the air source in the roof area has the advantage that this so claimed no space in the passenger compartment. Next, the air source may simply be connected to an air guide which just ^¬ case extends outside of the passenger compartment. The entire air conditioning system is arranged outside the passenger ^compartment . In a preferred embodiment, the air duct runs in the roof area and / or in a floor area of the first car body and in a floor area and / or roof area of the second car body. The intermediate space of the bellows connects the Roof area and / or the bottom portion of the first car body and the roof area and / or bottom portion of the second car body fluidically. Thus, the air from the air source, from the roof area of the first car into the roof area and / or floor area of the second car and / or the floor area of the first car can be conducted.

Thus, the air of the air source in the roof and floor area of both, especially the second car can be conducted. The air of the air source can be passed in the bottom and / or roof area of the first or the second car to all points of the corresponding car, without the line of air claimed space in the Passa ^¬ gierraum. Thus, the first carriage and the second Wa ^¬ gene can be supplied with air from the air source in the roof area of the first car. The need for a second air source in the second car is eliminated. The rail vehicle can be made simpler.

In a preferred embodiment, the air guide is configured such that the air from the air source, from the Dachbe ^¬ rich of the first car body in the passenger area of the first car body and / or the second box is conductive.

The air guide thus allows the passage of the air of the air source in the roof area of the first car in the passenger compartment of both the first and the second car. Thus, the air duct allows the use of an air source, so for example, a Kli ^¬ automation system, heating system or filter system for controlling the indoor climate of the passenger compartments of the first and the second car.

The air from a passenger area of the second car body is defined by a perimeter formed by the inner wall of the bellows. Transition in the passenger compartment of the first car body leitbarer. By the air guide air from the passenger area of the first car in the roof area of the first car body, in particular to the air source, can be conducted.

Thus, air from the passenger area of the first and / or the second carriage to the air source, in particular to a Luftkondi- tion plant, can be conducted. Thus, an air flow from the air ^¬ source via the air duct, in the passenger compartment of the two cars and the passenger compartment of the second car in the passenger compartment of the first car and from there back to the air source in the roof area of the first car is possible. Thus, the use of, for example, an air conditioner for both cars is made possible, wherein the air duct allows a closed in the vehicle air circulation.

To solve the problem also performs a bellows for Bil ^¬ tion of a transition between two cars. The bellows has a first air connection and at least one second air connection. The bellows is double-walled and between an inner wall of the bellows and an outer wall of the bellows forms a gap. Via the first air connection, air can be introduced into the intermediate space, in particular into the entirety of the intermediate space which is formed by the inner wall and outer wall. Via the second air supply air from the intermediate space, in particular the entirety of the interim ^¬ rule space which ge ^¬ forms by the inner wall and the outer wall is derived. The first air connection is formed from ^¬ such that it is connectable to an air source, so that air can be introduced into the intermediate space.

The intermediate space, in particular the entirety of the intermediate space which passes through the inner wall and the outer wall of the double wall gene bellows is formed forms a channel with a large ^¬ sen cross section. This channel can be used as an air duct for guiding air. The large channel cross-section leads to low air velocities with correspondingly low flow pressure losses and low noise development.

This eliminates the need for a separate air duct. The bellows allows the fluidic connection of a first car and a second car. This results in the possibility to use an air source for both the first car, as well as for the second car.

In a preferred embodiment, the first air connection is connectable to an upper connection section in a roof area of a car. The second air port is provided with a unte ^¬ ren connecting portion in a bottom portion of the carriage ver ^¬ bindable.

The first air connection and the second air connection allow the guidance of an air flow to the bellows. As a result, the bellows can be used as a partial channel of the air duct.

By using the bellows as a sub-channel, the air duct can be designed to be particularly cost-effective and space-saving.

To achieve the object according to a first aspect of the invention also leads to the use of a attachable between a first car and a second car bellows, in particular a double-walled or multi-walled bellows, in particular a gap which forms between an outer wall and an inner wall of the double-walled bellows its entirety as an air duct for conducting air from an air Source in the roof area (14) of the first car to a location to be cooled in an underfloor area (12) in the first car and / or the second car, in particular to one or more components in the underfloor area of the car, preferably Antriebskompo- components and / or energy supply components ,

 In a preferred use, the bellows of an air duct is used from a roof area of a first car in an underfloor area of the first car and / or the second car. The invention will be further explained below with reference to exemplary embodiments in FIGS. Hereby show:

FIG. 1 shows a schematic representation of a vehicle 1. The vehicle 1 comprises a first carriage 4 and a second carriage 6. The first carriage 4 and the second carriage 6 are supported on a common Jacob bogie 18 driven by drive motors 20. The first carriage 4 and the second carriage 6 each have a car body 8. The car bodies 8 each have a roof area 14.

Between the first carriage 4 and the second carriage 6 above the Jacob bogie 18, a transition 24, which is designed in the form of a bellows 26, attached. This transition is part of the cooling air duct 10. In the roof area 14 of the first carriage 4 is a ventilation fan 16 (not shown). The ventilation fan is located on the roof, outside the car body 8. This is connected by an upper connecting portion 38 with the bellows 26. The bellows 26 is double-walled and has an outer wall 30 and an inner wall 28 (see FIG. 3), as well as a gap 29. The bellows 26 is connected in the underfloor region 12 of the first car with two lower connecting portion 34. This lower connecting portions 34 lead into the underfloor region 12 of the first and second carriage 4,6 in the direction of the drive motors 20. The cooling air guide 10 consisting of the upper coupling portion 38, the folding ^¬ bellows 26 and the lower connecting portions 34 thus allows the guiding of cooling air from the Ventilation fan 16 in the roof area 14 of the first carriage 4 in the underfloor area 12 of the first and second carriage 4,6. In the underfloor region 12, the components, in particular the drive motors 20 are supplied by the cooling air flow with cooling air. Figure 2 shows an enlargement of a section through the vehicle 1 of Figure 1. The figure shows how the air of the air source (not shown) on the roof of the first carriage 4 is passed via the upper connecting portion 38 into the intermediate space 29 of the double-walled bellows , The intermediate space 29 is formed between the outer wall 30 and the inner wall 28 of the double-walled bellows 10.

FIG. 3 shows a section through the sectional plane AA of FIG. 1. The bellows 26 forms the transition 24 between the first carriage 4 and the second carriage 6 and is mounted on the bogie 18. The bellows 26 protects the passenger compartment 9 between the first carriage 4 and the second carriage 6. The bellows 26 consists of the inner wall 28 and the outer wall 30, thereby forming the intermediate space 29 therebetween.

The bellows 26 has a first air connection 44 in the roof area. By this air connection 44 air of the air source from the top connecting portion 38 is introduced into the interim ^¬ c region 29 of the bellows 26th The bellows 26 has a second air connection 46 in the vicinity of the bogie 18. This second air connection 46 connects the space 29 of the bellows 26 having a first lower connecting portion 34 (on the left) of the cooling air passage 10. The first lower coupling portion 34 is connected to a first gate 20 of the Antriebsmo ^¬ Jakob bogie 18th The bellows 26 has a third air connection 46 in the vicinity of the bogie 18. This third air port 46 connects the space 29 of the bellows 26 with a second lower connecting portion 34 (on the right) of the cooling air passage 10. The second lower connecting portion 34 is provided with a second on ^¬ drive motor 20 (not visible in Figure 3) connected to the Jakob bogie 18th As a result, cooling air can be supplied to the first and the second drive motor 20 in the underfloor area by blowing cooling air into the bellows 26 through an air source in the roof area. FIG. 4 shows the Jacob bogie 18 with two axles and a first and a second drive motor 20. Further, a part of the lower connecting portion 34 in the form of a fixed channel is shown by the drive motor 20. This part of the lower connecting portion 34 is fixed to the Jacob bogie and forms, together with a second elastic part of the lower connecting portion 34 (see Figure 1 and Figure 3), which lead to the bellows a cooling air guide for supplying cooling air from the bellows 26 to the drive motors 20th , Figure 5 shows the double-walled bellows 26, which is used as a transition 24 between the first carriage 4 and the second carriage 6. The bellows 26 has a first air connection 44, a second air port 46 and a drit ^¬ th air connection (in Figure 5 is not visible) which lead into the intermediate space 29th All air ports 44, 46 are formed in the form of a simple opening. The upper connection section 38 is connected to the intermediate space of the bellows 26 via the first air connection 44. The second air connection 46 and the third air connection connect the intermediate space of the bellows 26, each with a lower connecting section 34. So ^¬ probably the upper and the lower connecting portions are formed as a tube 42.

The first air connection 44 is matched in shape and size to the upper connection section 38. Thus, the cooling air can be introduced mög ^¬ lichst loss from the upper coupling portion 38 in the bellows 26th The bellows 26 thus forms an air channel accessible via the first, second and third air connection 44, 46.

The cooling air guide 10 thus allowing the guiding of the cooling air from the cooling air source (not shown) through the upper bonding ^¬ portion 38 into the space 29 of the bellows 26 and through the lower connecting portions 34 in the underfloor region of a railway vehicle (not shown). FIG. 6 shows the end face of a first carriage 4 of a ^further embodiment of the rail vehicle 1. At the front side of the first carriage 4, there is an opening at the top which represents one end of the upper connecting section 38 running in the carriage 4. represents, visible. The opening of the connecting portion 38 is in size and arrangement on the front side of the carriage 4 so out ^¬ leads, that the opening in the assembled state of the bellows 26 is completely covered by the intermediate space 29 of the bellows 26. The upper connecting portion 38 connects the so Zvi ^¬ c region 29 of the bellows with the arranged in the roof area 8 of the carriage 4 air source. The air source is arranged inside the Wa ^¬ genkastens. 8

FIG. 7 shows the bellows 26 which is suitable for the embodiment of FIG. 6 in the installed state, in which the bellows 26 is mounted between the first carriage 4 and the second carriage 6. The air of the cooling air source, which is located in the interior of the first carriage 4 is passed through the upper Verbindungsab ^{¬ section} 38 in the roof area of the first carriage 4 to the front side of the carriage 4 and the air connection 44 in the intermediate space 29 of the bellows 26.

Figure 8 shows a schematic representation of a vehicle 1 according to the second aspect of the invention.

Identical parts are identified by the same reference numerals. A repeated description will be omitted, see descrip ^¬ bung to FIG. 1

The vehicle 1 comprises an air conditioning system (not shown), which is connected via an air guide 10 with the first carriage 4 and the second carriage 6. The bellows 26 is double-walled and has an outer wall 30 and an inner wall 28 (not shown). Zvi ^¬ rule of the outer wall 30 and the inner wall 28 of the bellows 26 forms a gap 29 serving as a guide for the air Guiding air from the first car into the second carriage is availed. The inner wall 28 surrounds a passable by passengers transition. The air duct 10 has further in the roof areas 14 in the car bodies 8 extending, upper connecting portions 38.

In addition to the accessible by passengers transition which the Pas- sagierräume of the first carriage 4 and the second carriage 6 connects, the bellows 26 is formed by the gap 29 (see Figure 3) a further connection between the ers ^¬ th car 4 and the second Carriage 6. This further connection is formed by the gap 29 of the bellows 26. This connection connects the upper connecting sections 38 of the two carriages 4, 6 to each other.

The vehicle thus comprises two separate connections between the first carriage 4 and the second carriage 6, which are used for air guidance.

This allows the use of the air conditioner 16 for ventilation of both cars 4, 6. The supply air of the air conditioner 16 is guided by the passable by passengers transition from the first car 4 in the second carriage 6. This is shown in FIG. 1 by the thick arrow which points from right to left, that is to say from the first carriage 4 to the second carriage 6. Through the intermediate space 29 of the transition 24, the exhaust air from the second carriage 6 is guided back into the first carriage 4. This is illustrated in FIG. 1 by the four thin arrows which point from left to right, that is to say from the second carriage 6 to the first carriage 4. Figure 9 shows another embodiment of a rail ^¬ vehicle 1 according to the second aspect of the invention. The figure shows an air conditioner 16 which is mounted in the roof area 14 of the first car 4 (left). The supply air (small arrows) of the air conditioner 16 is passed through the air duct 10 in the first and second car 4 and a second car 6 and their passenger compartments 9. The exhaust air (large arrows) in the car 4.6 is then passed back to the air conditioner 16 via the passenger compartment 9.

For this purpose, the supply air of the air conditioner is supplied into an upper Verbin ^¬ dung portion 38 of the first carriage 4 sixteenth The connection ^¬ section 38 has openings in the passenger compartment 9 of the first carriage 4, whereby the supply air of the air conditioner 16 enters the passenger compartment 9 of the first carriage 4. The upper connecting portion 38 leads at the end face of the first carriage 4 into a gap 29 of a double-walled bellows 26. The intermediate space 29 is formed between an outer wall 30 and an inner wall 28 of the bellows 26. From the space 29, the supply air is in an upper connecting portion 38 of the second car 6 as well as in each one guided under connection portion 34 of the first and fourth carri ^¬ 4 wagon 6. From the Verbin ^¬ dung portions 34, 38, the supply air flows through in the connecting portions 34, 38 openings provided in the passenger space 9 of the first carriage 4 and the second carriage 6. The exhaust air of the passenger space 9 of the second carriage 6 is determined by the by the passenger compartment 9 formed the inner wall 28 between the cars 4,6 in the first car 4. The exhaust air can thus be sucked in again by the air conditioning system 16, cooled and redirected to the upper connecting section 38 of the first carriage 4. Thus, through the air duct 10, an air conditioning circuit in the first and second cars 4,6, with only one air conditioner 16 is required.
