Description

Die Erfindung betrifft ein Fahrwerk für Schienenfahrzeuge, das zumindest eine Tragestruktur, zumindest eine erste Primärfeder und eine zweite Primärfeder, zumindest eine erste Antriebsmotor-Getriebeeinheit, die über zumindest ein erstes Aufhängeelement mit der zumindest einen Tragestruktur verbunden ist, zumindest einen ersten Radsatz sowie zumindest eine erste Kupplung, die mit der zumindest ersten Antriebsmotor-Getriebeeinheit und dem zumindest ersten Radsatz verbunden ist, aufweist.The invention relates to a running gear for rail vehicles, which has at least one supporting structure, at least a first primary spring and a second primary spring, at least one first drive motor/gear unit, which is connected to the at least one supporting structure via at least one first suspension element, at least one first wheel set and at least one first clutch, which is connected to the at least first drive motor transmission unit and the at least first wheel set.

Aus dem Stand der Technik sind Fahrwerke mit unterschiedlichen Antriebs- und Getriebeaufhängungen sowie unterschiedlichen Koppelelementen zur Übertragung von Kräften und Drehmomenten aus Antriebsmotoren und Getrieben in Tragestrukturen bzw. Fahrwerksrahmen bekannt. Die EP 0 235 644 B1 offenbart ein Fahrwerk mit einem gegen eine Radsatzwelle gelagerten und über eine Anlenkeinrichtung mit einem Fahrwerksrahmen verbundenen Antriebsmotor. Die Anlenkeinrichtung weist zwei Lenkstangen auf. Weiterhin ist der Antriebsmotor über zwei Lager mit einer Radsatzwelle verbunden.Undercarriages with different drive and gear suspensions and different coupling elements for the transmission of forces and torques from drive motors and gears in supporting structures or undercarriage frames are known from the prior art. the EP 0 235 644 B1 discloses a running gear with a drive motor mounted against a wheelset shaft and connected to a running gear frame via an articulation device. The articulation device has two steering rods. Furthermore, the drive motor is connected to a wheel set shaft via two bearings.

Das US 4,046,080 beschreibt darüber hinaus das Prinzip des "Wegmann-Fahrwerks", bei dem ein Antriebsmotor auf einem Querträger gelagert ist. Zwischen dem Antriebsmotor, dem Getriebe und dem Querträger ist ein Stützlenker angeordnet. Weiterhin ist der Antriebsmotor mit einem Längsträger verbunden.That U.S. 4,046,080 also describes the principle of the "Wegmann chassis", in which a drive motor is mounted on a cross member. A support link is arranged between the drive motor, the transmission and the cross member. Furthermore, the drive motor is connected to a longitudinal member.

Die AT 514023 A1 offenbart ein Fahrwerk für ein Schienenfahrzeug, in dem eine Antriebseinheit über Federvorrichtungen mit elastischen Körpern gelagert ist. Die Antriebseinheit ist mit einer Radsatzwelle gekoppelt. Weiterhin beschreibt die WO 2009/056415 A1 ein Drehgestell mit einer Motoreinheit, die über drei Befestigungspunkte querelastisch mit einem Drehgestellrahmen verbunden ist. Ein achsreitendes Getriebe ist auf einer Radsatzwelle angeordnet und über eine Getriebe-Drehmomentstütze sowie eine Kupplung mit der Motoreinheit verbunden.the AT514023A1 discloses a running gear for a rail vehicle in which a drive unit is mounted via spring devices with elastic bodies. The drive unit is coupled to a wheelset shaft. Furthermore describes the WO 2009/056415 A1 a bogie with a motor unit that is transversely elastically connected to a bogie frame via three attachment points. An axle-riding gearbox is arranged on a wheelset shaft and connected to the motor unit via a gearbox torque arm and a clutch.

Die genannten Ansätze weisen in den bekannten Formen den Nachteil einer eingeschränkten Beweglichkeit der Radsatzwellen bzw. Radsätze in Abhängigkeit von Gleisgeometrie, Bogenradien, Gleislagefehlern etc. auf. Beispielsweise stützt sich der in der EP 0 235 644 B1 offenbarte Antriebsmotor an einer Radsatzwelle ab und erhöht einerseits deren Trägheit bezüglich Verdrehungen um eine Fahrwerkshochachse sowie andererseits ungefederte Massen des Fahrwerks.In the known forms, the approaches mentioned have the disadvantage of limited mobility of the wheelset shafts or wheelsets depending on the track geometry, curve radii, track position errors, etc. For example, the one in the EP 0 235 644 B1 disclosed drive motor on a wheelset shaft and increases on the one hand their inertia with respect to rotations about a chassis vertical axis and on the other hand unsprung masses of the chassis.

Dadurch ergeben sich eine hohe Belastung der Radsätze sowie ausgeprägter Verschleiß an den Rädern sowie ein hohes Fahrgeräuschniveau.This results in a high load on the wheel sets and pronounced wear on the wheels as well as a high driving noise level.

Weiterhin wären bei einem Einsatz einer aktiven Radsatzsteuerung mit Radsatzstelleinrichtungen, wie sie unter anderem zur Stabilisierung von Fahrzuständen sowie aus Fahrkomfortgründen vorgesehen sein kann, hohe Stellkräfte erforderlich, um eine Verdrehung von Radsätzen um eine Fahrwerkshochachse zu bewirken.Furthermore, when using an active wheel set control with wheel set adjusting devices, such as can be provided, among other things, to stabilize driving conditions and for reasons of driving comfort, high actuating forces would be required in order to cause wheel sets to rotate about a vertical axis of the running gear.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Fahrwerk anzugeben.The invention is therefore based on the object of specifying a running gear that is improved over the prior art.

Erfindungsgemäß wird diese Aufgabe gelöst mit einem Fahrwerk der eingangs genannten Art, bei dem die zumindest erste Antriebsmotor-Getriebeeinheit mit der zumindest einen Tragestruktur über ein vorwiegend in Richtung einer Fahrwerkslängsachse belastbares erstes Koppelelement verbunden ist.According to the invention, this object is achieved with a chassis of the type mentioned at the outset, in which the at least first drive motor/gear unit is connected to the at least one support structure via a first coupling element that can be loaded primarily in the direction of a chassis longitudinal axis.

Während das erste Aufhängeelement in Bezug auf die erste Antriebsmotor-Getriebeeinheit eine Lagerungsfunktion ausführt, werden über das erste Koppelelement vorwiegend Kräfte in Richtung der Fahrwerkslängsachse von der ersten Antriebsmotor-Getriebeeinheit auf die Tragestruktur übertragen. Lagerungs- und Längskraftübertragungsfunktionen sind folglich voneinander getrennt ausgeführt.While the first suspension element performs a bearing function in relation to the first drive motor gear unit, forces in the direction of the chassis longitudinal axis are primarily transmitted from the first drive motor gear unit to the support structure via the first coupling element. Storage and longitudinal force transmission functions are therefore designed separately from one another.

Dadurch werden eine definierte Längskrafteinleitung in die Tragestruktur und folglich ein günstiger Kraft- und Drehmomentenverlauf in der Tragestruktur erzielt, der wiederum eine vorteilhafte Beweglichkeit der Tragestruktur relativ zu dem ersten Radsatzes bewirkt. Radsatzstelleinrichtungen von aktiven Radsatzsteuerungen können kompakt ausgeführt sein.As a result, a defined introduction of longitudinal force into the support structure and consequently a favorable course of force and torque in the support structure are achieved, which in turn causes an advantageous mobility of the support structure relative to the first wheel set. Wheelset actuating devices of active wheelset controls can be designed to be compact.

Es ist beispielsweise möglich, nur eine Radsatzstelleinrichtung je Radsatzseite vorzusehen.For example, it is possible to provide only one wheel set adjusting device for each wheel set side.

Erfindungsgemäß ist eine erste Querschnittfläche des ersten Koppelelements in einer vertikalen Längsmittelebene der zumindest einen Tragestruktur angeordnet.According to the invention, a first cross-sectional area of the first coupling element is arranged in a vertical longitudinal center plane of the at least one support structure.

Dabei ergibt sich eine besonders vorteilhafte Lösung, wenn die erste Querschnittfläche mittig in dem ersten Koppelelement angeordnet ist.A particularly advantageous solution results if the first cross-sectional area is arranged centrally in the first coupling element.

Erfindungsgemäß erfolgt eine annähernd oder exakt mittige Längskrafteinleitung von der ersten Antriebsmotor-Getriebeeinheit in die Tragestruktur. Somit wird eine weitere Verbesserung des Kraft- und Drehmomentenverlaufs in der Tragestruktur erzielt. Drehmomente, die gegen Verdrehungen der Tragestruktur relativ zu dem ersten Radsatz um eine Fahrwerkshochachse wirken, werden reduziert.According to the invention, longitudinal force is introduced approximately or exactly in the middle from the first drive motor/gear unit into the support structure. A further improvement in the course of force and torque in the support structure is thus achieved. Torques that act against twisting of the support structure relative to the first wheel set about a vertical axis of the running gear are reduced.

Erfindungsgemäß ist eine zweite Querschnittfläche der zumindest ersten Kupplung in einer vertikalen Quermittelebene des zumindest ersten Radsatzes angeordnet.According to the invention, a second cross-sectional area of the at least first clutch is arranged in a vertical transverse center plane of the at least first wheel set.

Dabei ist es besonders günstig, wenn die zweite Querschnittfläche mittig in der zumindest ersten Kupplung angeordnet ist.It is particularly favorable here if the second cross-sectional area is arranged centrally in the at least first clutch.

2 Erfindungsgemäß erfolgt eine annähernd oder exakt mittige Einleitung von Antriebs- und Bremskräften bzw. Antriebs- und Bremsmomenten aus der Antriebsmotor-Getriebeeinheit über die erste Kupplung in den ersten Radsatz.According to the invention, driving and braking forces or driving and braking torques from the drive motor-gear unit are introduced approximately or exactly in the middle via the first clutch into the first wheel set.

Drehmomente, die gegen Verdrehungen des ersten Radsatzes relativ zu der Tragestruktur um eine Fahrwerkshochachse wirken, werden reduziert. Drehbewegungen des ersten Radsatzes um Fahrwerkshochachsen, welche mangels einer Abstützung der Antriebsmotor-Getriebeeinheit auf dem ersten Radsatz (beispielsweise über entsprechende Lager auf einer Radsatzwelle) und aufgrund daraus resultierender geringer Trägheiten des ersten Radsatzes und geringer ungefederter Massen des Fahrwerks mit geringem Widerstand ausführbar sind, werden weiter erleichtert.Torques that act against twisting of the first wheel set relative to the support structure about a vertical axis of the running gear are reduced. Rotational movements of the first wheel set about the vertical axes of the running gear, which can be carried out with little resistance due to the lack of support for the drive motor/gear unit on the first wheel set (e.g. via appropriate bearings on a wheel set shaft) and due to the resulting low inertia of the first wheel set and low unsprung masses of the running gear further relieved.

Dadurch werden in Zusammenhang mit den geringen ungefederten Massen des Fahrwerks insbesondere in Gleisbögen mechanische Belastungen und Verschleiß des ersten Radsatzes sowie Fahrgeräusche gesenkt.In connection with the low unsprung masses of the running gear, this reduces mechanical loads and wear on the first wheel set, especially in curved tracks, as well as driving noise.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention is explained in more detail below using exemplary embodiments.

Es zeigen beispielhaft:

Die Tragestruktur 1 kann einteilig oder mehrteilig ausgeführt sein. Bei mehrteiligen Ausführungsformen ist es beispielsweise möglich, einzelne Teile gelenkig miteinander zu verbinden etc.a in 1 Section of an exemplary variant of a running gear according to the invention for a rail vehicle shown in a plan view comprises a support structure 1 designed as a running gear frame with a cross member 3 and a first longitudinal member 4 and a second longitudinal member 5. According to the invention, with regard to geometry, connection technology, materials, etc., various embodiments of Support structures 1 conceivable. The supporting structure 1 can be made in one piece or in several pieces. In the case of multi-part embodiments, it is possible, for example, to connect individual parts to one another in an articulated manner, etc.

Das Fahrwerk weist weiterhin einen quer liegenden Antriebsmotor und ein Getriebe auf, die über ein gemeinsames Gehäuse zu einer ersten Antriebsmotor-Getriebeeinheit 8 verbunden sind.The chassis also has a transverse drive motor and a gearbox, which are connected via a common housing to form a first drive motor/gear unit 8 .

Ein erster Radsatz 21 ist über ein erstes Radsatzlager mit einem ersten Radsatzlagergehäuse 24, ein zweites Radsatzlager mit einem zweiten Radsatzlagergehäuse 25 sowie über in Fig. 1 nicht gezeigte Radsatzführungseinrichtungen an die Tragestruktur 1 gekoppelt.A first wheel set 21 is connected via a first wheel set bearing to a first wheel set bearing housing 24, a second wheel set bearing to a second wheel set bearing housing 25 and via in 1 not shown Radsatzführungseinrichtungen coupled to the support structure 1.

Der erste Radsatz 21 umfasst ein erstes Rad 26, ein zweites Rad 27 sowie eine Radsatzwelle 23. Das Fahrwerk weist eine Innenlagerung auf, das erste Radsatzlager mit dem ersten Radsatzlagergehäuse 24 und das zweite Radsatzlager mit dem zweiten Radsatzlagergehäuse 25 sind in einem Bereich zwischen dem ersten Rad 26 und dem zweiten Rad 27 angeordnet. Erfindungsgemäß sind jedoch auch außengelagerte Varianten vorstellbar.The first wheel set 21 comprises a first wheel 26, a second wheel 27 and a wheel set shaft 23. The running gear has internal bearings, the first wheel set bearing with the first wheel set bearing housing 24 and the second wheel set bearing with the second wheel set bearing housing 25 are in an area between the first Wheel 26 and the second wheel 27 arranged. According to the invention, however, externally mounted variants are also conceivable.

Weiterhin sind zwischen dem ersten Radsatz 21 und der Tragestruktur 1 eine erste Primärfeder 6 und eine zweite Primärfeder 7 vorgesehen. Die Tragestruktur 1 ist demzufolge primärgefedert.Furthermore, a first primary spring 6 and a second primary spring 7 are provided between the first wheel set 21 and the support structure 1 . The supporting structure 1 is therefore primarily spring-loaded.

Die erste Antriebsmotor-Getriebeeinheit 8 ist über ein elastisches erstes Aufhängeelement 9 und ein elastisches zweites Aufhängeelement 10 gelenkig auf der Tragestruktur 1 gelagert. Das erste Aufhängeelement 9 und das zweite Aufhängeelement 10 sind als faserverstärkte Gummielemente ausgeführt. Erfindungsgemäß ist es jedoch auch denkbar, das erste Aufhängeelement 9 und das zweite Aufhängeelement 10 aus einem metallischen Werkstoff auszuführen.The first drive motor gear unit 8 is an elastic first suspension member 9 and an elastic second suspension element 10 articulated on the support structure 1. The first suspension element 9 and the second suspension element 10 are designed as fiber-reinforced rubber elements. According to the invention, however, it is also conceivable for the first suspension element 9 and the second suspension element 10 to be made of a metallic material.

Über das erste Aufhängeelement 9 und das zweite Aufhängeelement 10 werden insbesondere Vertikal- und Querkräfte von der ersten Antriebsmotor-Getriebeeinheit 8 auf die Tragestruktur 1 übertragen. Eine Übertragung von Kräften in Richtung einer Fahrwerkslängsachse 12 erfolgt nur in einem vernachlässigbaren Ausmaß.In particular, vertical and transverse forces are transmitted from the first drive motor gear unit 8 to the support structure 1 via the first suspension element 9 and the second suspension element 10 . Forces are only transmitted to a negligible extent in the direction of a chassis longitudinal axis 12 .

Zwischen der ersten Antriebsmotor-Getriebeeinheit 8 und dem Querträger 3 der Tragestruktur 1 ist weiterhin genau ein als Sphärolager ausgebildetes elastisches erstes Koppelelement 11 angeordnet. Das erste Koppelelement 11 weist eine Buchse 17 auf, durch die ein Knochen 14 hindurch geführt ist. Der Knochen 14 weist im Kontakt mit der Buchse 17 eine Elastomerschicht auf, wodurch eine Schwingungsdämpfung erzielt wird. Der Knochen 14 ist über einen ersten Adapter 15 und einen zweiten Adapter 16, die mit der ersten Antriebsmotor-Getriebeeinheit 8 verbunden sind, mit der ersten Antriebsmotor-Getriebeeinheit 8 mittels Schraubenverbindungen verbunden.Between the first drive motor gear unit 8 and the crossbeam 3 of the support structure 1, exactly one elastic first coupling element 11 designed as a spherical bearing is furthermore arranged. The first coupling element 11 has a socket 17 through which a bone 14 is guided. The bone 14 has an elastomeric layer in contact with the bushing 17, which provides vibration damping. The bone 14 is connected to the first drive motor gear unit 8 via a first adapter 15 and a second adapter 16 connected to the first drive motor gear unit 8 by means of screw connections.

Das erste Koppelelement 11 ist radial, axial, auf Torsion sowie kardanisch, jedoch insbesondere in Richtung der Fahrwerkslängsachse 12 belastbar. Eine erste Querschnittfläche 13 des ersten Koppelelements 11 liegt in einer vertikalen, in Fig. 1 projizierend erscheinenden Längsmittelebene 2 der Tragestruktur 1.The first coupling element 11 can be loaded radially, axially, torsionally and cardanically, but in particular in the direction of the longitudinal axis 12 of the running gear. A first cross-sectional area 13 of the first coupling element 11 lies in a vertical, in 1 projecting longitudinal center plane 2 of the support structure 1.

In Bezug auf einen Bereich zwischen dem ersten Längsträger 4 und dem zweiten Längsträger 5 ist das erste Koppelelement 11 mittig angeordnet. Kräfte und Drehmomente, insbesondere Kräfte in Richtung der Fahrwerkslängsachse 12 werden von der ersten Antriebsmotor-Getriebeeinheit 8 über deren Gehäuse sowie über das erste Koppelelement 11 mittig in den Querträger 3 eingeleitet.The first coupling element 11 is arranged centrally in relation to an area between the first longitudinal member 4 and the second longitudinal member 5 . Forces and torques, in particular forces in the direction of the longitudinal axis 12 of the chassis, are transmitted by the first drive motor/gear unit 8 via its housing and introduced centrally into the cross member 3 via the first coupling element 11 .

Dadurch ergeben sich ein günstiger Kraft- und Drehmomentenverlauf in der Tragestruktur 1 und eine gute Beweglichkeit der Tragestruktur 1 relativ zu dem ersten Radsatz 21.This results in a favorable course of force and torque in the support structure 1 and good mobility of the support structure 1 relative to the first wheel set 21.

Antriebs- und Bremskräfte bzw. Antriebs- und Bremsmomente werden von dem Antriebsmotor über das Getriebe sowie eine über eine Hohlwelle 18 auf dem ersten Radsatz 21 gelagerte erste Kupplung 19 auf den ersten Radsatz 21 übertragen.Driving and braking forces or driving and braking torques are transmitted from the drive motor to the first wheel set 21 via the transmission and a first clutch 19 mounted on the first wheel set 21 via a hollow shaft 18 .

Eine zweite Querschnittfläche 20 der ersten Kupplung 19 liegt in einer in Fig. 1 projizierend erscheinenden Quermittelebene 22 des ersten Radsatzes 21. Die erste Kupplung 19 ist in Bezug auf einen Bereich zwischen Enden des ersten Radsatzes 21 mittig angeordnet. Antriebs- und Bremskräfte bzw. Antriebs- und Bremsmomente aus der ersten Antriebsmotor-Getriebeeinheit 8 werden daher mittig in den ersten Radsatz 21 eingeleitet.A second cross-sectional area 20 of the first clutch 19 lies in a 1 The first clutch 19 is arranged centrally in relation to an area between ends of the first wheel set 21 . Driving and braking forces or driving and braking torques from the first drive motor/gear unit 8 are therefore introduced centrally into the first wheel set 21 .

Die Quermittelebene 22 des ersten Radsatzes 21 liegt in der Längsmittelebene 2 der Tragestruktur 1. Es ist z.B. bei Radsatzbewegungen jedoch auch möglich, dass die Quermittelebene 22 einen Versatz von der Längsmittelene 2 oder eine Verdrehung gegenüber der Längsmittelebene 2 etc. aufweist.The transverse center plane 22 of the first wheel set 21 lies in the longitudinal center plane 2 of the support structure 1. However, it is also possible, e.g. during wheel set movements, for the transverse center plane 22 to be offset from the longitudinal center plane 2 or rotated relative to the longitudinal center plane 2, etc.

Aufgrund der mittig in den ersten Radsatz 21 eingeleiteten Antriebs- und Bremskräfte bzw. Antriebs- und Bremsmomente wird ein günstiger Kraft- und Drehmomentenverlauf in dem ersten Radsatz 21 erzielt.Because of the driving and braking forces or driving and braking torques that are introduced centrally into the first wheel set 21 , a favorable force and torque curve is achieved in the first wheel set 21 .

Drehmomente, welche gegen Verdrehungen des ersten Radsatzes 21 um eine Fahrwerkshochachse wirken, werden reduziert. Der erste Radsatz 21 weist dadurch insbesondere bei Verdrehungen um eine Fahrwerkshochachse eine gute Beweglichkeit auf und es werden Belastungen und Verschleiß des ersten Radsatzes 21 sowie Fahrgeräusche reduziert.Torques, which act against twisting of the first wheel set 21 about a vertical axis of the running gear, are reduced. As a result, the first wheel set 21 has good mobility, in particular when rotated about a vertical axis of the running gear, and loads and wear on the first wheel set 21 and driving noise are reduced.

Bei einer aktiven Radsatzsteuerung müssen für Lenkwinkeländerungen des ersten Radsatzes 21, d.h. Verdrehungen des ersten Radsatzes 21 um eine Fahrwerkshochachse lediglich geringe Stellkräfte aufgebracht werden.In the case of an active wheel set control, only small actuating forces have to be applied for changing the steering angle of the first wheel set 21, i.e. twisting the first wheel set 21 about a vertical axis of the running gear.

Der erste Längsträger 4 weist eine aktive erste Radsatzstelleinrichtung 28 auf, die als pneumatischer Aktuator ausgebildet ist.The first side member 4 has an active first wheel set adjusting device 28 which is designed as a pneumatic actuator.

Erfindungsgemäß ist es auch möglich, die erste Radsatzstelleinrichtung 28 beispielsweise als hydraulischer Aktuator auszuführen.According to the invention, it is also possible to embody the first wheel set adjusting device 28 as a hydraulic actuator, for example.

In dem ersten Längsträger 4, bzw. von dem ersten Längsträger 4 ummantelt, ist ein Zylinder 29 angeordnet, in dem ein Kolben 30 geführt ist. Ein mit dem Kolben 30 verbundener Stempel 31 ist über eine Öffnung in einen Außenbereich des ersten Längsträgers 4 geführt und mit dem ersten Radsatzlagergehäuse 24 verbunden.In the first longitudinal member 4, or encased by the first longitudinal member 4, a cylinder 29 is arranged, in which a piston 30 is guided. A plunger 31 connected to the piston 30 is guided through an opening into an outer area of the first side member 4 and connected to the first wheel set bearing housing 24 .

Erfindungsgemäß ist es beispielsweise auch möglich, die erste Radsatzstelleinrichtung 28 an einer Außenseite der Tragestruktur 1 zu lagern.According to the invention, it is also possible, for example, to mount the first wheel set adjusting device 28 on an outside of the support structure 1 .

Der Zylinder 29 kann über in Fig. 1 nicht dargestellte Druckluftleitungen, welche den pneumatischen Aktuator mit einem in Fig. 1 ebenfalls nicht gezeigten Druckluftsystem des Schienenfahrzeugs verbinden, sowie über in Fig. 1 nicht dargestellte Druckluftanschlüsse mit Druckluft gefüllt werden. Über einen Druck in dem Zylinder 29 wird eine Kraft auf den Kolben 30 und auf den Stempel 31 erzeugt, welche über das erste Radsatzlagergehäuse 24 als Stellkraft auf den ersten Radsatz 21 übertragen wird. Aufgrund der Stellkraft wird der erste Radsatz 21 um eine in Fig. 1 nicht gezeigte, projizierend erscheinende Fahrwerkshochachse verdreht, d.h. es wird ein Lenkwinkel des ersten Radsatzes 21 entsprechend einer Gleisgeometrie eingestellt.The cylinder 29 can be 1 Compressed air lines, not shown, which connect the pneumatic actuator with an in 1 connect compressed air system of the rail vehicle, also not shown, as well as via in 1 Compressed air connections, not shown, are filled with compressed air. A pressure in the cylinder 29 generates a force on the piston 30 and on the plunger 31 which is transmitted via the first wheel set bearing housing 24 as an actuating force to the first wheel set 21 . Due to the actuating force, the first wheel set 21 is moved by one in 1 not shown, projecting appearing chassis vertical axis twisted, ie a steering angle of the first wheel set 21 is adjusted according to a track geometry.

Der Druck in dem Zylinder 29 und somit die Stellkraft werden über eine in Fig. 1 nicht dargestellte Regeleinheit des Schienenfahrzeugs entsprechend des erforderlichen Lenkwinkels geregelt.The pressure in the cylinder 29 and thus the actuating force are controlled via an in 1 not shown control unit of Rail vehicle regulated according to the required steering angle.

In Fig. 1 nicht dargestellt ist eine zweite Antriebsmotor-Getriebeeinheit, welche im Hinblick auf konstruktive und verbindungstechnische Prinzipien gleich wie die erste Antriebsmotor-Getriebeeinheit 8 ausgeführt ist. Für eine Kraftübertragung von der zweiten Antriebsmotor-Getriebeeinheit auf die Tragestruktur 1 in Richtung der Fahrwerkslängsachse 12 ist demzufolge ein elastisches zweites Koppelelement vorgesehen. Das zweite Koppelelement ist bezüglich eines Bereichs zwischen dem ersten Längsträger 4 und dem zweiten Längsträger 5 mittig auf dem Querträger 3 angeordnet.In 1 not shown is a second drive motor-gear unit, which is designed in the same way as the first drive motor-gear unit 8 with regard to structural and connection-technical principles. Accordingly, an elastic second coupling element is provided for power transmission from the second drive motor gear unit to the support structure 1 in the direction of the longitudinal axis 12 of the running gear. The second coupling element is arranged centrally on the cross member 3 with respect to an area between the first longitudinal member 4 and the second longitudinal member 5 .

Antriebs- und Bremskräfte bzw. Antriebs- und Bremsmomente werden von der zweiten Antriebsmotor-Getriebeeinheit über eine zweite Kupplung in einen zweiten Radsatz eingeleitet. Die zweite Kupplung ist in Bezug auf einen Bereich zwischen Enden des zweiten Radsatzes mittig angeordnet. Der zweite Radsatz ist im Hinblick auf konstruktive Prinzipien sowie lagerungs- und koppelungstechnisch gleich wie der erste Radsatz 21 ausgeführt.Driving and braking forces or driving and braking torques are introduced into a second wheel set by the second drive motor/gear unit via a second clutch. The second clutch is centered with respect to an area between ends of the second gear set. The second wheel set is designed in the same way as the first wheel set 21 in terms of design principles and storage and coupling technology.

Erfindungsgemäß sind beispielsweise auch Fahrwerke mit drei Radsätzen (z.B. für Lokomotiven) oder mit nur einem Radsatz vorstellbar.According to the invention, for example, bogies with three wheel sets (e.g. for locomotives) or with only one wheel set are also conceivable.

Auf dem zweiten Längsträger 5 ist, in Fig. 1 nicht dargestellt, eine zweite Radsatzstelleinrichtung angeordnet, die Stellkräfte auf den zweiten Radsatz bewirkt. Die zweite Radsatzstelleinrichtung ist hinsichtlich funktionaler und konstruktiver Prinzipien gleich wie die erste Radsatzstelleinrichtung 28 ausgeführt.On the second longitudinal member 5 is, in 1 not shown, arranged a second Radsatzstelleinrichtung which causes actuating forces on the second wheel set. With regard to functional and structural principles, the second wheel set actuating device is designed in the same way as the first wheel set actuating device 28 .

Bei der Anordnung der ersten Radsatzstelleinrichtung 28 und der zweiten Radsatzstelleinrichtung handelt es sich um eine günstige Lösung. Erfindungsgemäß sind jedoch auch Fahrwerke mit passiven oder semiaktiven Radsatzführungen bzw. ohne aktive Radsatzführungen bzw. Radsatzstelleinrichtungen denkbar.The arrangement of the first wheel set setting device 28 and the second wheel set setting device is a favorable solution. However, the invention also includes chassis with passive or semi-active wheelset guidance or without active wheelset guides or wheelset setting devices are conceivable.
