Definitions
- the invention relates to a rail vehicle with a roof air duct, which is arranged below a roof panel of the rail vehicle.
- the attic duct is an integral part of an air distribution system for hot and cold air.
- the roof air duct establishes a connection between a compact air conditioning unit frequently arranged on a roof of the rail vehicle to air outlets to a passenger compartment of the rail vehicle.
- the roof air conditioning solutions are known in which it is made of solid materials, such as metal, and constructed in the longitudinal direction of the rail vehicle adjoining channel segments.
- This variant for the execution of the roof air conditioning duct is attached in segments along the rail vehicle to designated holders. These holders are attached to a shell of the rail vehicle, for example on an underside of the roof panel.
- the segments of the roof air conditioning duct must be interconnected and sealed from the rest of the interior space of the rail vehicle.
- the segments often have a rectangular cross section for reasons of cost and production and are arranged between the passenger compartment and the roof of the rail vehicle.
- the installation of such a roof air conditioning channel is thus designed to be very expensive, since both the individual roof air duct segments are to be fastened to each other as well as the rail vehicle shell. It also results from the fact that both the vehicle body shell and the roof air duct are provided individually with insulation material. Often there is a double insulation, which would not be necessary per se.
- JP 2001 163217 A and JP 2001 163217 A show various embodiments for the integration of a roof air conditioning duct into a vehicle. In each variant described there, separate fasteners are required to fix the roof air duct at a desired position in the roof area of the vehicle.
- the invention has the object, a rail vehicle of the type mentioned in that further develop that results in a simplified assembly.
- the roof panel is constructed of individual, in the longitudinal direction of the rail vehicle extending extruded profiles (2) which adjoin one another transversely to the rail vehicle, in the roof panel two downwardly projecting, in the longitudinal direction of the rail vehicle parallel to each other extending, webs are integrated formed on a lower side of two of the extruded profiles and forming at least a portion of side walls of the roof air conditioning duct, wherein a portion of the roof panel extending between the webs in the transverse direction of the rail vehicle forms a ceiling of the roof air conditioning duct and the roof air conditioning duct has an elongate floor member attached to the webs is connected airtight.
- the side walls of the roof air conditioning duct can only be partially formed by the webs.
- the bottom member may also have a generally C-shaped cross section, the legs of which form a lower portion of the side walls.
- the webs completely form the side walls of the roof air conditioning duct. This results in a simple mold to be produced for the elongated floor element required for closing the roof air conditioning duct.
- the roof air conditioning duct can, for example, also be realized on a typically curved high roof of a rail vehicle. For realizing a rectangular cross-section, however, it is preferred if the roof panel is formed flat.
- the bottom element may be airtight connected at the lower edges of the web-like extruded profiles. As a result, a completion of the roof air conditioning duct is brought about in a simple manner.
- the sides of the webs facing the inside of the roof air conditioning duct and the section of the roof panel extending between the webs can be covered with insulating material.
- duplications are effectively prevented in an insulation that can otherwise be caused by a modular design with a separate roof air duct.
- the webs and thus also the roof air conditioning duct as a whole preferably extend over at least half the length of the roof panel of the rail vehicle.
- there is a roof air duct which is straight over a large length and without deflections. This also brings acoustic benefits by minimizing flow noise and a low pressure drop of the roof air conditioning duct with it.
- the floor element may have a perforated ceiling for supplying air into a passenger compartment of the rail vehicle. This causes a favorable distribution of, for example, air-conditioned Air from the roof air duct into the passenger compartment.
- FIG. 1 shows a rail vehicle roof here a flat roof forming roof panel 1, which is composed of individual, in the longitudinal direction of the rail vehicle (here a single car body) extending aluminum extruded profiles 2, which adjoin one another transverse to the rail vehicle.
- the roof panel 1 is part of a shell of the rail vehicle and is supported laterally on side walls 3.
- On an underside of two of the extruded profiles 2 separate extruded profiles 4 are provided which protrude vertically from the roof panel 1 down, extending in the longitudinal direction of the rail vehicle parallel to each other and are web-shaped. These extruded profiles 4 are integrated in the roof panel 1.
- the webs 4 are already provided in the production of the extruded profiles.
- the webs 4 extend over at least 40%, preferably 50% to 60%, of a total length of a respective car body of the rail vehicle.
- the percentage basically depends on a length ratio between flat roof and high roof areas.
- the webs 4 are arranged mirror-symmetrically with respect to a vertical longitudinal center plane of the rail vehicle. A in the transverse direction of the rail vehicle between the webs 4 extending portion 5 of the roof panel 1 on the underside forms a ceiling of a roof air conditioning duct 6 (see. Fig. 2 ). The webs 4 contrast form side walls of the roof air conditioning channel. 6
- An underside of the roof panel 1 is covered with an insulating layer 7, in particular also the section 5 of the roof panel 1, and is pierced by the webs 4.
- FIG. 2 is now the formation of the roof air conditioning duct 6 completely clear.
- Still open bottom of the roof air conditioning duct 6 is airtight closed by means of an elongated bottom element 8, which is fixed to the lower edges of the webs 4. This happens, for example, via upwardly directed edge-side webs of the floor element, which then overlap with the extruded profiles 4 and are screwed thereto.
- An underside of the floor element 8 is formed by a perforated ceiling 9, so that guided in the roof air conditioning duct 6, conditioned air can pass through the perforated ceiling 9 into a vehicle interior of the rail vehicle.
- roof air conditioning duct 6 insides of the webs 4 are covered with insulating material 10 so that the roof air duct 6 is a total of acoustically isolated in particular.
- the construction of the roof air conditioning duct 8 can then take place in such a way that already the roof plate comprises the webs 4.
- the insulation of the underside of the roof panel 1 and the insides of the webs 4 can be made in one go.
- the bottom element 8 of the roof air conditioning duct 6 and any interfaces in the longitudinal direction of the car body for connection to a compact air conditioner, a silencer or the completion of the roof air conditioning duct 6 are added later, so that the roof air duct 6 is then completely closed.

Description
Die Erfindung bezieht sich auf ein Schienenfahrzeug mit einem Dachklimakanal, der unterhalb einer Dachplatte des Schienenfahrzeugs angeordnet ist.The invention relates to a rail vehicle with a roof air duct, which is arranged below a roof panel of the rail vehicle.
Bei einem solchen Schienenfahrzeug ist der Dachklimakanal wesentlicher Bestandteil eines Luftverteilsystems für Warm- und Kaltluft. Dabei stellt der Dachklimakanal eine Verbindung zwischen einem häufig auf einem Dach des Schienenfahrzeugs angeordneten Kompaktklimagerät zu Luftauslässen zu einem Fahrgastinnenraum des Schienenfahrzeugs her.In such a rail vehicle, the attic duct is an integral part of an air distribution system for hot and cold air. In this case, the roof air duct establishes a connection between a compact air conditioning unit frequently arranged on a roof of the rail vehicle to air outlets to a passenger compartment of the rail vehicle.
Zur Ausbildung des Dachklimakanals sind Lösungen bekannt, bei denen er aus festen Materialien, wie Metall, hergestellt und aus in Längsrichtung des Schienenfahrzeugs aneinander anschließenden Kanalsegmenten aufgebaut ist. Diese Variante zur Ausführung des Dachklimakanals wird entlang des Schienenfahrzeugs segmentweise an vorgesehenen Haltern befestigt. Diese Halter sind an einem Rohbau des Schienenfahrzeugs angebracht, beispielsweise an einer Unterseite der Dachplatte. Zusätzlich müssen die Segmente des Dachklimakanals untereinander verbunden und gegenüber dem restlichen Innenraum des Schienenfahrzeugs abgedichtet werden. Die Segmente haben aus Kostengründen und fertigungsbedingt häufig einen rechteckigen Querschnitt und sind zwischen dem Fahrgastinnenraum und dem Dach des Schienenfahrzeugs angeordnet. Die Montage eines solchen Dachklimakanals gestaltet sich somit als sehr aufwendig, da sowohl die einzelnen Dachklimakanal-Segmente untereinander als auch am Schienenfahrzeugrohbau zu befestigen sind. Auch ergibt es sich dadurch, dass sowohl der Fahrzeugrohbau als auch der Dachklimakanal einzeln mit Isolationsmaterial versehen werden. Häufig liegt eine Doppelisolation vor, die an sich nicht notwendig wäre.For the formation of the roof air conditioning solutions are known in which it is made of solid materials, such as metal, and constructed in the longitudinal direction of the rail vehicle adjoining channel segments. This variant for the execution of the roof air conditioning duct is attached in segments along the rail vehicle to designated holders. These holders are attached to a shell of the rail vehicle, for example on an underside of the roof panel. In addition, the segments of the roof air conditioning duct must be interconnected and sealed from the rest of the interior space of the rail vehicle. The segments often have a rectangular cross section for reasons of cost and production and are arranged between the passenger compartment and the roof of the rail vehicle. The installation of such a roof air conditioning channel is thus designed to be very expensive, since both the individual roof air duct segments are to be fastened to each other as well as the rail vehicle shell. It also results from the fact that both the vehicle body shell and the roof air duct are provided individually with insulation material. Often there is a double insulation, which would not be necessary per se.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Schienenfahrzeug der eingangs genannten Art insofern weiterzuentwickeln, dass sich eine vereinfachte Montage ergibt.Proceeding from this, the invention has the object, a rail vehicle of the type mentioned in that further develop that results in a simplified assembly.
Diese Aufgabe wird bei dem Schienenfahrzeug durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved in the rail vehicle by the characterizing features of
Danach ist vorgesehen, dass die Dachplatte aus einzelnen, in Längsrichtung des Schienenfahrzeugs verlaufenden Strangpressprofilen (2) aufgebaut ist, die sich quer zum Schienenfahrzeug aneinander anschließen, in die Dachplatte zwei nach unten vorstehende, sich in Längsrichtung des Schienenfahrzeugs parallel zueinander erstreckende, Stege integriert sind, die an einer Unterseite von zweien der Strangpressprofile vorgesehen sind und wenigstens einen Abschnitt von Seitenwänden des Dachklimakanals bilden, wobei ein sich in Querrichtung des Schienenfahrzeugs zwischen den Stegen erstreckender Abschnitt der Dachplatte eine Decke des Dachklimakanals bildet und der Dachklimakanal ein langgestrecktes Bodenelement aufweist, das an die Stege luftdicht angeschlossen ist.Thereafter, it is envisaged that the roof panel is constructed of individual, in the longitudinal direction of the rail vehicle extending extruded profiles (2) which adjoin one another transversely to the rail vehicle, in the roof panel two downwardly projecting, in the longitudinal direction of the rail vehicle parallel to each other extending, webs are integrated formed on a lower side of two of the extruded profiles and forming at least a portion of side walls of the roof air conditioning duct, wherein a portion of the roof panel extending between the webs in the transverse direction of the rail vehicle forms a ceiling of the roof air conditioning duct and the roof air conditioning duct has an elongate floor member attached to the webs is connected airtight.
Gegenüber dem Stand der Technik verminderter Montageaufwand ergibt sich dadurch, dass wenigstens ein vertikaler Abschnitt der Stege sowie der horizontale Abschnitt der Dachplatte zwischen den Strangpressprofilen bereits drei Seiten eines Dachklimakanals ausbilden. Für eine Vervollständigung des Dachklimakanals ist es nur noch erforderlich, das Bodenelement von unten an die Stege anzusetzen und zu befestigen.Compared to the prior art reduced assembly costs result from the fact that form at least a vertical portion of the webs and the horizontal portion of the roof panel between the extruded sections already three sides of a roof air conditioning duct. For a completion of the roof air conditioning duct, it is only necessary to attach the floor element from below to the webs and secure.
Die Seitenwände des Dachklimakanals können nur teilweise von den Stegen ausgebildet werden. In diesem Fall kann das Bodenelement auch einen allgemein C-förmigen Querschnitt aufweisen, dessen Schenkel einen unteren Abschnitt der Seitenwände bilden. Es ist jedoch bevorzugt, dass die Stege die Seitenwände des Dachklimakanals vollständig ausbilden. Dann ergibt sich eine einfache herzustellende Form für das zum Verschließen des Dachklimakanals erforderliche langgestreckte Bodenelement.The side walls of the roof air conditioning duct can only be partially formed by the webs. In this case, the bottom member may also have a generally C-shaped cross section, the legs of which form a lower portion of the side walls. However, it is preferred that the webs completely form the side walls of the roof air conditioning duct. This results in a simple mold to be produced for the elongated floor element required for closing the roof air conditioning duct.
Der Dachklimakanal kann beispielsweise auch an einem typischerweise gekrümmten Hochdach eines Schienenfahrzeugs verwirklicht werden. Zur Realisierung eines rechtwinkligen Querschnitts ist es jedoch bevorzugt, wenn die Dachplatte flach ausgebildet ist.The roof air conditioning duct can, for example, also be realized on a typically curved high roof of a rail vehicle. For realizing a rectangular cross-section, however, it is preferred if the roof panel is formed flat.
Das Bodenelement kann an unteren Rändern der stegartigen Strangpressprofile luftdicht angeschlossen sein. Dadurch wird in einfacher Weise eine Vervollständigung des Dachklimakanals herbeigeführt.The bottom element may be airtight connected at the lower edges of the web-like extruded profiles. As a result, a completion of the roof air conditioning duct is brought about in a simple manner.
Vorteilhafterweise können die einem Inneren des Dachklimakanals zugewandten Seiten der Stege und des sich zwischen den Stegen erstreckenden Abschnitts der Dachplatte mit Isolationsmaterial belegt sein. In dieser Weise werden Doppelungen bei einer Isolation, die sonst durch eine modulare Bauweise mit gesondertem Dachklimakanal entstehen können, wirksam verhindert.Advantageously, the sides of the webs facing the inside of the roof air conditioning duct and the section of the roof panel extending between the webs can be covered with insulating material. In this way duplications are effectively prevented in an insulation that can otherwise be caused by a modular design with a separate roof air duct.
Die Stege und damit auch der Dachklimakanal insgesamt erstrecken sich bevorzugt über wenigstens die Hälfte der Länge der Dachplatte des Schienenfahrzeugs. In diesem Fall ergibt sich ein Dachklimakanal, der über eine große Länge gerade und ohne Umlenkungen ist. Dies bringt auch akustische Vorteile durch die Minimierung von Strömungsgeräuschen sowie einen geringen Druckverlust des Dachklimakanals mit sich. Es ergeben sich weniger Schnittstellen im Dachklimakanal als wenn er, wie im Stand der Technik bekannt, aus vielen Segmenten aufgebaut ist. Dies trägt ebenfalls zur Dichtigkeit des Dachklimakanals bei. Die sich daraus ergebende geringere Leckageluftmenge verringert Energieverluste des Luftverteilsystems, zu dem der Dachklimakanal gehört.The webs and thus also the roof air conditioning duct as a whole preferably extend over at least half the length of the roof panel of the rail vehicle. In this case, there is a roof air duct, which is straight over a large length and without deflections. This also brings acoustic benefits by minimizing flow noise and a low pressure drop of the roof air conditioning duct with it. There are fewer interfaces in the roof air duct than when, as is known in the art, it is made up of many segments. This also contributes to the tightness of the roof air conditioning duct. The resulting lower amount of leakage air reduces energy losses of the air distribution system to which the attic duct belongs.
Das Bodenelement kann eine Lochdecke zur Zuführung von Luft in einen Fahrgastinnenraum des Schienenfahrzeugs aufweisen. Dies bewirkt eine günstige Verteilung von beispielsweise klimatisierter Luft aus dem Dachklimakanal in den Fahrgastinnenraum.The floor element may have a perforated ceiling for supplying air into a passenger compartment of the rail vehicle. This causes a favorable distribution of, for example, air-conditioned Air from the roof air duct into the passenger compartment.
