Abstract

The present invention pertains to a truck frame for railway rolling stock with a two-axle undercarriage secured by means of a primary suspension to a frame on which, through the intermediate setting (28, 29) of a secondary suspension, a hinged bracket (30) is mounted, transversally oriented relative to the direction of movement, said hinged bracket (30) being attached through oscillation about an axle oriented longitudinally relative to the car to an inclinable cross-bar bearing the car body. This cross-bar is designed as a frame and has two crossbearers (46, 47) mounted prior to or past the hinged bracket (30), while the crossbearers (46, 47) take their bearing against the hinged bracket in direction of movement and are mounted transversally mobile relative to direction of movement. Furthermore, the crossbar has preferably a central segment (50, 51, 52) connected to the frame (2) of the undercarriage to absorb the longitudinal forces through a guide in the form of a lemniscate, so that the cross-bar (31) can rotate about a substantially vertical axis and hinge in a substantially transversal plane relative to the direction of movement.

Description

Die Erfindung bezieht sich auf ein Drehgestell-Fahrwerk für ein Schienenfahrzeug, insbesondere für einen Hochgeschwindigkeitszug, mit einem zweiachsigen Laufwerk, welches über eine Primärfederung an einem Rahmen befestigt ist, an welchem unter Zwischenschaltung einer Sekundärfederung ein quer zur Fahrzeuglängsrichtung ausgerichteter Pendelträger angeordnet ist, welcher über eine Viergelenks-Pendellagerung um eine in Fahrzeuglängsrichtung verlaufende Achse schwenkbar mit einer querliegenden Traverse verbunden ist, bei welcher Viergelenks-Pendellagerung zwei Pendel symmetrisch zur Längsmittelebene des Fahrwerks und -von vorne bzw. hinten gesehen - trapezförmig angeordnet sind, wobei der seitliche Abstand der Anlenkpunkte der Pendel an dem Pendelträger geringer als der seitliche Abstand der darunter liegenden Anlenkpunkte der Pendel an der Traverse ist, auf die der Wagenkasten des Fahrzeuges unmittelbar aufsetzbar ist, wobei zwischen dem Pendelträger und der Traverse eine aktive Neigestellungseinrichtung mit wenigstens einer Stelleinheit, z. B. einer quer zur Fahrzeuglängsrichtung und im wesentlichen liegend angeordneten Zylinder/Kolbeneinheit, vorgesehen istThe invention relates to a bogie chassis for a rail vehicle, in particular for a high-speed train with a two-axle drive, which has a Primary suspension is attached to a frame, on which a Secondary suspension is arranged a pendulum carrier aligned transversely to the vehicle longitudinal direction is, which has a four-joint pendulum bearing around a running in the vehicle longitudinal direction Axis is pivotally connected to a transverse crossbar, in which four-joint self-aligning bearing two pendulums symmetrical to the longitudinal median plane of the chassis and from seen in front or rear - are arranged trapezoidal, the lateral distance of the Articulation points of the pendulums on the pendulum carrier are less than the lateral distance between them the articulation points of the pendulum on the traverse to which the vehicle body of the vehicle is located can be put on immediately, with an active between the pendulum support and the traverse Tilt position device with at least one actuating unit, e.g. B. one transverse to the vehicle longitudinal direction and cylinder / piston unit arranged substantially horizontally

Ein Fahrwerk der oben genannten Art ist beispielsweise in der DE-C-2 145 738 in zwei unterschiedlichen Ausführungsvarianten beschrieben. Die Sekundärfederung für den Pendelträger wird üblicherweise durch Luftfedern gebildet, die auf dem Rahmen des Fahrwerks aufsitzen und den Pendelträger im Bereich seiner seitlichen Enden abstützen. Die Traverse ist über eine mechanische Gelenks-anordnung um eine horizontale Schwenkachse verschwenkbar mit dem Pendelträger in der Weise verbunden, daß die Schwenkachse im Bereich oberhalb der Traverse im Wagenkasten, z. B. in Fahrgasthöhe liegt. Dadurch kann die Neigemechanik mit geringem Kraftaufwand betneben werden. Wenn die Schwenkachse oberhalb oder unterhalb des Wagenschwerpunktes angeordnet ist, wird die Neigemechanik überdies durch die Wirkung einer Rückstellkraft in Ihren Ausgangszustand gebracht. Da die Neigemechanik mechanisch über den Luftfedern angeordnet ist, wird sie durch Erschütterungen wenig belastet, da diese durch die Primär und Sekundärfederung größtenteils absorbiert werden. Ein Nachteil dieser Anordnung liegt unter anderem jedoch darin, daß durch die sekundärgefederte Neigemechanik eine hohe Bauhöhe erreicht wird, welche sich als nachteilig erwiesen hat.A chassis of the type mentioned above is, for example, in DE-C-2 145 738 in two different Design variants described. The secondary suspension for the pendulum support is usually formed by air springs that sit on the frame of the chassis and support the pendulum support in the area of its lateral ends. The traverse is over one mechanical joint arrangement pivotable about a horizontal pivot axis with the Pendulum carrier connected in such a way that the pivot axis in the area above the crossbar in the car body, e.g. B. is at passenger height. This allows the tilting mechanism to be operated with little Be exerted. If the swivel axis is above or below the center of gravity is arranged, the tilt mechanism is also by the action of a Restoring force brought into its initial state. Since the tilt mechanics mechanically over the Air springs is arranged, it is little stressed by vibrations, as this by the Primary and secondary suspension are largely absorbed. A disadvantage of this arrangement is, among other things, that the secondary spring tilt mechanism means a high level Height is reached, which has proven to be disadvantageous.

Ein ähnliches Fahrwerk geht aus der DE 43 43 998 Al hervor, wobei eine nicht rahmenförmige Wagenkastentraverse an den Pendelträger zwar verschwenkbar, nicht jedoch verschiebbar angeordnet ist. A similar undercarriage emerges from DE 43 43 998 A1, with a non-frame-shaped one Carriage body crossbar on the pendulum support can be pivoted, but not displaceable is arranged.

Eine sekundärgefederte Neigestellmechanik für ein Drehgestell eines Schienenfahrzeuges, welche eine niedrige Bauhöhe ermöglicht, ist unter anderem in den EP 736 437 und EP 736 438 dargestellt und beschrieben. Diese Neigestellmechanik umfaßt einen sekundärgefederten Pendelträger, an welchem über ein Viergelenk direkt der Wagenkasten angelenkt ist, wobei an der Oberseite des Pendelträgers an seinen beiden Enden hydraulische Zylinder/Kolbeneinheiten angreifen, die an den zugeordneten Seitenwänden des Wagenkastens in einem Abstand oberhalb des Pendelträgers abgestützt sind. Ein wesentlicher Nachteil dieser Konstruktion liegt unter anderem darin, daß durch die Integration der Neigestellmechanik in die Wagenkastenkonstruktion weniger Fahrgastraum und demnach weniger Platz für Sitzplätze zur Verfügung steht. Ferner muß bei einer solchen Konstruktion sowohl das Fahrwerk als auch der Wagenkasten an einem Fabrikationsort hergestellt und zusammengebaut werden. Überdies muß der Wagenkasten zur Aufnahme der auftretenden Kräfte entsprechend dimensioniert werden, sodaß die Produktionskosten eines solchen Wagenkastens erhöht sind. Da die Krafteinleitungspunkte für die Neigestellmechanik vergleichsweise hoch und demnach in einem geringeren Abstand von dem Wagenschwerpunkt liegen, müssen zur Neigung des Wagenkastens in unerwünschter Weise höhere Kräfte überwunden werden.A secondary spring tilt mechanism for a bogie of a rail vehicle, which enables a low overall height is described, inter alia, in EP 736 437 and EP 736 438 shown and described. This tilting mechanism includes a secondary spring Pendulum bracket, on which the car body is directly linked via a four-bar linkage, with hydraulic cylinder / piston units at the top of the pendulum support at both ends attack that on the associated side walls of the car body in are supported a distance above the pendulum support. A major disadvantage of this Construction lies in the fact that by integrating the tilting mechanism in the car body construction less passenger space and therefore less space for seats is available. Furthermore, with such a construction, both the chassis and the car body is manufactured and assembled at a manufacturing site. Moreover the car body must be dimensioned accordingly to absorb the forces that occur are, so that the production costs of such a car body are increased. Because the force application points comparatively high for the tilting mechanism and therefore in one less distance from the center of gravity of the car, must be inclined to the car body higher forces are undesirably overcome.

Bei dem Fahrwerk nach der DE 2 001 282 A liegt eine vergleichsweise komplizierte Aufhängung vor, die nicht nur Pendel, sondern auch Winkelhebel und ein Lenkergetriebe aufweist. Zwei außen gelegene Stelleinheiten sind vor bzw. hinter dem Rahmen vorgesehen.The chassis according to DE 2 001 282 A has a comparatively complicated suspension before, which not only has pendulums, but also angle levers and a steering gear. Two external actuators are provided in front of and behind the frame.

Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Drehgestell-Fahrwerk für ein Schienenfahrzeug der eingangs genannten Art so zu verbessern, daß eine kompakte Anordnung mit möglichst geringer Baulänge und geringer Bauhöhe geschaffen werden kann, die dennoch eine klare und einfache Schnittstelle zum Wagenkasten ermöglicht.It is therefore an object of the present invention to provide a bogie undercarriage for a rail vehicle to improve the type mentioned so that a compact arrangement with the smallest possible length and height can be created, which is nevertheless a allows clear and simple interface to the car body.

Diese Aufgabe wird bei einem Drehgestell-Fahrwerk der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Traverse als Rahmen mit zwei quer zur Fahrzeuglängsrichtung ausgerichteten, vor bzw. hinter dem Pendelträger angeordneten Traversenquerträgern ausgebildet ist, und daß diese Traversenquerträger in Fahrzeuglängsrichtung an dem Pendelträger abstützbar und quer zur Fahrzeuglängsrichtung an diesem verschiebbar angeordnet sind. Durch die rahmenförmige Ausgestaltung der Traverse für den Wagenkasten können der Pendelträger und die Traverse ineinander verschachtelt und im wesentlichen auf gleicher Höhe angeordnet werden, sodaß sich die Bauhöhe des Fahrwerks erheblich verringern läßt, ohne daß hiefür der Wagenkasten verändert werden muß. Durch die rahmenförmige Ausgestaltung der Traverse um den Pendelträger herum kann die Traverse ausreichend stabil bei geringem Platzbedarf in Längsrichtung hergestellt werden, wodurch auch eine geringe Baulänge des Fahrgestells erzielt werden kann. This object is achieved according to the invention in a bogie undercarriage of the type mentioned at the beginning solved in that the traverse as a frame with two transverse to the vehicle longitudinal direction aligned, arranged in front of or behind the pendulum crossmember and that these cross-member cross members in the vehicle longitudinal direction on the pendulum support are supported and slidably arranged transversely to the longitudinal direction of the vehicle. By the frame-shaped design of the cross beam for the car body can be the pendulum carrier and the traverse nested and arranged at substantially the same height are, so that the overall height of the chassis can be significantly reduced without the Car body must be changed. Due to the frame-shaped design of the crossbar around the pendulum support, the traverse can be sufficiently stable in a small space Longitudinal direction are produced, which also achieves a small overall length of the chassis can be.

Eine vorteilhafte Realisierung des erfindungsgemäßen Fahrwerks ist in der Praxis dadurch möglich, daß zur Abstützung und Führung der Traversenquerträger an dem Pendelträger je zwei symmetrisch zur Längsmittelebene des Fahrwerks angeordnete Reibplatten und an jedem Traversenquerträger gegenüberliegend angeordnete Reibflächen vorgesehen sind. Diese Reibplatten/Reibflächenanordnung ermöglicht eine ausreichende Längsmitnahme und ist im Sinne einer möglichst kompakten Bauweise bei geringem Platzverbrauch realisierbar.An advantageous implementation of the chassis according to the invention is in practice possible that depending on the support and guidance of the crossbeam on the pendulum support two friction plates arranged symmetrically to the longitudinal center plane of the undercarriage and on each Truss cross members are provided opposite friction surfaces. This Friction plates / friction surface arrangement allows sufficient longitudinal driving and is in Realizable in terms of the most compact possible construction with little space consumption.

Eine besonders vorteilhafte Ausgestaltung der Pendel ergibt sich, wenn jedes Pendel aus einer Mehrzahl von Federstahlblechen hergestellt ist, welche flächig aneinandergeschichtet sind und mittels je eines gemeinsamen Bolzens an dem Pendelträger bzw. der Traverse angelenkt sind. Da Federstahlbleche in ihrer Längsrichtung eine hohe Zugfestigkeit aufweisen, können die Pendel äußerst schmal gebaut werden, wodurch sich die Kompaktheit des Fahrwerks weiter verbessert. Weiters sind die Pendel quer zur Zugrichtung, also in Fahrzeuglängsrichtung elastisch und ermöglichen somit in vorteilhafter Weise eine gewisse Elastizität zum Ausgleich von Toleranzen zwischen dem Pendelträger und der Traverse.A particularly advantageous embodiment of the pendulum results if each pendulum consists of one A plurality of spring steel sheets is made, which are laminated together and are articulated to the pendulum support or the crossmember by means of a common bolt each. Since spring steel sheets have a high tensile strength in their longitudinal direction, the Pendulums are built extremely narrow, which further increases the compactness of the chassis improved. Furthermore, the pendulums are transverse to the direction of pull, i.e. in the longitudinal direction of the vehicle elastic and thus advantageously allow a certain elasticity to compensate of tolerances between the pendulum support and the crossbeam.

Die Bolzen für die Pendel können mittels je eines Gleit- oder Wälzlagers an dem Pendelträger bzw. der Traverse gelagert sein. In der Praxis ist es von Vorteil, wenn die Pendellagerung vier paarweise angeordnete Pendel aufweist, wobei je zwei Pendel in Längsrichtung des Fahrwerks hintereinander angeordnet sind.The pins for the pendulums can be attached to the pendulum carrier by means of a sliding or roller bearing or the traverse. In practice, it is advantageous if the pendulum bearing four has pendulums arranged in pairs, two pendulums each in the longitudinal direction of the chassis are arranged one behind the other.

Eine platzsparende, einfache und kostengünstige Realisierung der Neigestellmechanik ist im Rahmen der vorliegenden Erfindung dadurch möglich, daß die Neigestelleinrichtung eine einzige Zylinder/Kolbeneinheit aufweist, die unterhalb des Pendelträgers angeordnet ist, wobei ein Ende der Zylinder/Kolbeneinheit in einem Abstand von der Längsmittelebene mit dem Pendelträger und das andere Ende an der gegenüberliegenden Fahrwerksseite in einem Abstand von der Längsmittelebene mit der Traverse verbunden ist.A space-saving, simple and inexpensive realization of the tilting mechanism is in the Within the scope of the present invention possible in that the tilting device a has only cylinder / piston unit, which is arranged below the pendulum support, wherein one end of the cylinder / piston unit at a distance from the longitudinal median plane with the Pendulum bracket and the other end on the opposite side of the chassis at a distance is connected to the traverse from the longitudinal median plane.

Die Kompaktheit der Anordnung wird weiters dadurch verbessert, daß die Traverse einen die beiden Querträger unterhalb des Pendelträgers verbindenden zentralen Mittelabschnitt aufweist, der zur Aufnahme von Längskräften über eine Lemniskatenführung mit dem Rahmen des Fahrwerks in der Weise verbunden ist, daß die Traverse um eine vertikale Achse drehbar und im wesentlichen quer zur Fahrtrichtung auslenkbar ist. Die Traverse bildet somit eine stabile Konstruktion, welche den Pendelträger bis auf seine Oberseite umschließt.The compactness of the arrangement is further improved by the fact that the crossbar one has two crossbeams connecting the central central section below the pendulum beam, which for absorbing longitudinal forces via a lemniscate guide with the frame of the Undercarriage is connected in such a way that the traverse can be rotated about a vertical axis and is deflectable essentially transversely to the direction of travel. The crossbeam thus forms a stable one Construction that encloses the pendulum carrier up to its top.

Der Pendelträger ist zur Aufnahme von zwischen Fahrwerk und Wagenkasten auftretenden Querkräften in an sich bekannter Weise über eine aktive Querfederung und -dämpfung mit dem Rahmen des Fahrwerks verbunden, wobei vor und hinter dem Pendelträger je ein aktives Querfeder- und -dämpfungselement vorgesehen ist und die Feder- und Dämpfungselemente im Bereich der Längsmittelebene an dem Pendelträger angreifen. Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Fahrwerks ist zur Verbindung von dem Pendelträger mit der aktiven Querfederung bzw. -dämpfung im Mittelabschnitt der Traverse eine Öffnung vorgesehen, durch welche ein Verbindungsstück des Pendelträgers unterhalb der Traversenquerträger nach vorne bzw. nach hinten geführt ist. Hierdurch kann die Querfederung außerhalb der Verschachtelung von Traverse und Pendelträger am Rahmen des Fahrwerks angeordnet werden.The pendulum support is designed to accommodate those occurring between the chassis and the body Lateral forces in a manner known per se via an active transverse suspension and damping with the Frame of the chassis connected, one in front and one behind the pendulum support Cross spring and damping element is provided and the spring and damping elements in Attack the area of the longitudinal median plane on the pendulum support. In a preferred embodiment of the chassis according to the invention is for connection of the pendulum support with the active transverse suspension or damping, an opening is provided in the central section of the traverse, through which a connecting piece of the pendulum beam below the crossmember is led forward or backward. This allows the transverse suspension outside of The crossbar and pendulum support are nested on the frame of the chassis become.

Der Pendelträger kann weiters im Bereich seiner seitlichen Enden mit einer an sich bekannten Wankstabilisierung versehen sein, welche zu beiden Seiten des Rahmens je einen unterhalb des Pendelträgers angeordneten, um eine horizontale Quersachse an dem Rahmen angelenkten, in Fahrzeuglängsrichtung und im wesentlichen horizontal ausgerichteten Wankstabilisatorhebel aufweist, der über je eine nach oben gerichtete Zug-Druckstange mit dem zugeordneten Ende des Pendelträgers verbunden ist, wobei die quer zur Fahrtrichtung einander gegenüberliegend angeordneten Stabilisatorhebel mittels einer Torsionsstange miteinander federnd verbunden sind. Um die Wirkung der Wankstabilisierung weiter zu verbessern, ist bei einer bevorzugten Ausführungsform des erfindungsgemäßen Fahrwerks der Stabilisatorhebel der Wankstabilisierung über eine Dämpfeinrichtung, die in einem Abstand von der Anlenkachse des Stabilisatorhebels an diesem angreift, an dem Rahmen abgestützt. Für die Praxis ist es von Vorteil, wenn die Wankstabilisierung durch vier Stabilisatorhebel und Zug-Druckstangen gebildet wird, wobei je zwei Stabilisatorhebel und Zug-Druckstangen in Fahrtrichtung hintereinander und symmetrisch zur Fahrwerkslängsmitte angeordnet sind.The pendulum support can also in the region of its lateral ends with a known per se Roll stabilization should be provided, which one on each side of the frame below the Pendulum carrier arranged around a horizontal transverse axis hinged to the frame in Vehicle longitudinal direction and substantially horizontally aligned roll stabilizer lever has, each via an upward push-push rod with the associated end of the pendulum carrier is connected, the opposite to each other transversely to the direction of travel Arranged stabilizer lever connected to each other resiliently by means of a torsion bar are. To further improve the effect of roll stabilization, one is preferred Embodiment of the chassis of the stabilizer lever of the roll stabilization according to the invention via a damping device, which is at a distance from the articulation axis of the stabilizer lever attacks this, supported on the frame. In practice it is an advantage if the roll stabilization is formed by four stabilizer levers and pull-push rods, where two stabilizer levers and pull-push rods in the direction of travel and one behind the other are arranged symmetrically to the longitudinal center of the chassis.

Weiters ist bei einer vorteilhaften Ausführungsform des erfindungsgemäßen Fahrwerks vorgesehen, daß die Traverse an ihren seitlichen Enden über je eine gegen die Fahrwerksausdrehung wirkende Drehdämpfung mit dem Rahmen verbunden ist, um Schlingerbewegungen des Drehgestells abzufangen.Furthermore, in an advantageous embodiment of the undercarriage according to the invention, that the traverse at its lateral ends each against the chassis rotation acting rotary damping is connected to the frame to roll the Intercept bogie.

Der Pendelträger liegt im Bereich seiner seitlichen Enden in an sich bekannter Weise über je eine die Sekundärfederung bildende Luftfeder auf dem Rahmen auf, wobei der Innenraum des hohlen Pendelträgers in vorteilhafter Weise als zusätzliches Volumen der Luftfedern in die Sekundärfederung integriert ist.The pendulum support lies in the area of its lateral ends in a manner known per se above an air spring forming the secondary suspension on the frame, the interior of the hollow pendulum carrier in an advantageous manner as an additional volume of the air springs in the Secondary suspension is integrated.

Bei einer Ausführungsform, bei welcher jede Achse des Fahrwerks einen elektrischen Antrieb aufweist hat es sich als vorteilhaft erwiesen, wenn dieser Antrieb an der dem Pendelträger zugewandten Seite der Radachse angeordnet ist, da hierdurch eine kompakte Bauweise mit geringem Trägheitsmoment erzielt werden kann. Weiter ist zur Realisierung eines möglichst kompakten Fahrwerks von Vorteil, wenn jedes Rad des Fahrwerks mit je einer Radscheibenbremse versehen ist und die Teile der Bremsmechanik an der dem Pendelträger zugewandte Seite der Radachse angeordnet sind.In one embodiment, in which each axle of the undercarriage has an electric drive it has proven to be advantageous if this drive on the pendulum support facing side of the wheel axle is arranged, as a result of this having a compact design low moment of inertia can be achieved. Next is to realize one if possible compact chassis is an advantage if each wheel of the chassis has a wheel disc brake is provided and the parts of the brake mechanism facing the pendulum support Side of the wheel axle are arranged.

Eine vorteilhafte Ausgestaltung des Rahmens ist dadurch möglich, daß der Innenraum des hohlen Rahmens zumindest abschnittsweise mit den Luftfedern verbunden und in das Volumen der Luftfedern integriert ist, da durch diese Maßnahme eine kompakte Realisierung der Sekundärfederung bei geringer Bauhöhe ermöglicht wird.An advantageous embodiment of the frame is possible in that the interior of the hollow frame at least in sections connected to the air springs and in the volume the air springs is integrated, as a result of this measure a compact implementation of the secondary suspension is made possible with a low overall height.

  • Vorerst wird auf die Figuren 1 bis 3 Bezug genommen, in welchen ein Drehgestell-Fahrwerk 1 der erfindungsgemäßen Art dargestellt ist. Das Fahrwerk 1 weist einen H-förmigen Rahmen 2 auf, der durch je zwei Längsträger 3, 4 und zwei je zwei Querträger 5, 6 gebildet wird, die miteinander verschweißt sind. An dem vorderen und dem hinteren Ende des Rahmens 2 ist je ein Radsatz bestehend aus zwei gegenüberliegend angeordneten Rädern 7, 8, 9, 10 vorgesehen, die mittels je einer Achse 11, 12 starr miteinander verbunden sind. Die über eine Primärfederstufe mit dem Rahmen 2 verbundenen Räder 7, 8, 9, 10 sind an je einer Schwinge 13, 14 drehbar gelagert, die um eine Querachse S1, S2 schwenkbar an den Längsträgern 3, 4 des Rahmens 2 angelenkt ist. Die Primärfederung wird durch zwei auf Druck belastete Schraubenfedern 15, 16, 17, 18 je Schwinge 13, 14 gebildet, wobei die vertikal angeordneten Federn 15, 16, 17, 18 mit ihrem unteren Ende an der zugeordneten Schwinge 13, 14 und mit ihrem oberen Ende gegen den zugeordneten Längsträger 3, 4 des Rahmens 2 abgestützt sind. Die Federkonstanten sind in Abhängigkeit von ihrem Abstand von der Schwingenachse S1, S2 so ausgelegt, daß bei einem Einfedern der Primärfederung nach Möglichkeit an der Schwingenachse S1, S2 keine Vertikalkräfte auftreten. Die Schwingenlagerung der Räder mittels je zwei Primärfedern bietet den Vorteil, daß die Primärfederstufe kompakt gebaut werden kann und das Fahrwerk demnach eine geringere Bauhöhe erreicht. Weiters wird durch die im Durchmesser kleinere Feder 16, 18 zusätzlich Platz geschaffen, der für die Anordnung einer Radscheibenbremse genutzt werden kann.For the time being, reference is made to FIGS. 1 to 3, in which a bogie chassis 1 of the type according to the invention is shown. The chassis 1 has an H-shaped frame 2 on, which is formed by two side members 3, 4 and two two cross members 5, 6 each are welded together. At the front and rear ends of the frame 2 is each a wheel set consisting of two wheels 7, 8, 9, 10 arranged opposite one another is provided, which are rigidly connected to each other by means of an axis 11, 12. The one Primary spring stage with the frame 2 connected wheels 7, 8, 9, 10 are each on a rocker 13, 14 rotatably mounted, which is pivotable about a transverse axis S1, S2 on the longitudinal beams 3, 4th the frame 2 is articulated. The primary suspension is pressurized by two Coil springs 15, 16, 17, 18 each rocker 13, 14 formed, the vertically arranged Springs 15, 16, 17, 18 with their lower end on the associated rocker 13, 14 and with their upper end are supported against the associated side members 3, 4 of the frame 2. The spring constants are dependent on their distance from the rocker axis S1, S2 designed so that when the primary suspension deflects as far as possible on the Swing axis S1, S2 no vertical forces occur. The swing arm bearings of the wheels Using two primary springs each has the advantage that the primary spring stage is compact can be and the chassis therefore has a lower overall height. Furthermore, through the smaller diameter spring 16, 18 created additional space for the arrangement a wheel disc brake can be used.

    Das in den Figuren gezeigte Ausführungsbeispiel betrifft ein zweiachsiges Fahrgestell, bei welchem jede Achse angetrieben ist. Zu diesem Zweck ist an den Achsen 11, 12 je ein achsreitendes Getriebe 19, 20, z.B. ein Zahnradgetriebe aufgesetzt, welches über eine Kupplung, z.B. über eine Bogenzahnkupplung mit je einem querliegenden Antriebsmotor 21, 22 verbunden ist. Die Antriebsmotoren 21, 22 sind an dem zugeordneten Querträger 5 bzw. 6 des Rahmens 2 befestigt, wobei die Relativbewegungen zwischen dem rahmenfesten Motor und dem primärgefederten Getriebe von der Kupplung aufgenommen werden. Antriebe dieser Art sind dem Fachmann auf dem Gebiet der Drehgestell-Fahrwerke bekannt und werden daher an dieser Stelle nicht im Detail beschrieben. Wesentlich für die Realisierung eines möglichst kompakten Fahrwerks, insbesondere für Hochgeschwindigkeitsanwendungen ist jedoch die Anordnung aller wesentlichen mechanischen Komponenten der Antriebe jeweils an der der Fahrwerkslängsmitte zugewandten Seite der Achsen 11, 12.The embodiment shown in the figures relates to a two-axle chassis, at which each axis is driven. For this purpose there is one on each of the axes 11, 12 axle-mounted gear 19, 20, e.g. a gear transmission, which has a Clutch, e.g. via a curved tooth coupling, each with a transverse drive motor 21, 22 is connected. The drive motors 21, 22 are on the associated cross member 5 and 6, respectively attached to the frame 2, the relative movements between the frame-fixed motor and the primary suspension gearbox are taken up by the clutch. Drives this Art are known to those skilled in the art of bogie chassis and are therefore not described in detail here. Essential for realizing one if possible compact chassis, especially for high-speed applications Arrangement of all essential mechanical components of the drives each on the Longitudinal center side of axles 11, 12.

    Die Räder 7, 8, 9, 10 des Fahrwerks 1 sind mit je einer Bremseinheit 23, 24, 25, 26 einer sogenannten Radscheibenbremse versehen. Die Bremseinheiten 23, 24, 25, 26 sind rahmenfest an den Querträgern 5, 6 des Rahmens 2 befestigt und weisen je eine Bremszange auf, deren Bremsbacken an den Seitenflächen der betreffenden Räder 7, 8, 9, 10 angreifen, welche zu beiden Seiten mit je einer Bremsscheibe versehen sind. Bremseinrichtungen dieser Art sind dem Fachmann ebenso bereits bekannt und werden demnach an dieser Stelle nicht näher erläutert. 1m Rahmen der vorliegenden Erfindung ist im Sinne einer kompakten Bauweise jedoch wesentlich, daß die mechanischen Komponenten der Bremseinheiten 23, 24, 25, 26 an der der Fahrwerkslängsmitte zugewandten Seite der Räder 7, 8, 9, 10 angeordnet sind, da sich diese Anordnung durch ein geringeres Trägheitsmoment begünstigend auf die Grenzgeschwindigkeit des Fahrwerks auswirkt.The wheels 7, 8, 9, 10 of the chassis 1 are each with a brake unit 23, 24, 25, 26 so-called wheel disc brake. The brake units 23, 24, 25, 26 are fixed to the frame attached to the cross beams 5, 6 of the frame 2 and each have a brake caliper, the Attack brake shoes on the side surfaces of the wheels 7, 8, 9, 10 concerned, which too both sides are provided with a brake disc. Braking devices of this type are the Those skilled in the art are also already known and are therefore not explained in more detail here. Within the scope of the present invention, however, is in the sense of a compact design essential that the mechanical components of the brake units 23, 24, 25, 26 on the Longitudinal center side of the wheels 7, 8, 9, 10 are arranged, since these Arrangement due to a lower moment of inertia favoring the limit speed of the chassis affects.

    An der Unterseite der Längsträger 3, 4 des Rahmens 2 ist im Bereich zwischen den Rädern 7, 9 bzw. 8, 10 je eine Schienenbremse 27 vorgesehen.On the underside of the longitudinal beams 3, 4 of the frame 2 is in the area between the wheels 7, 9 or 8, 10 each have a rail brake 27 provided.

    An der Oberseite der Längsträger 3, 4 des Rahmens 2 ist im Bereich der Fahrwerkslängsmitte je eine Luftfeder 28, 29 für die Sekundärfederung des Fahrwerks 1 angeordnet. Auf die quer gegenüberliegend angeordneten Luftfedern 28, 29 ist ein querliegender Pendelträger 30 aufgesetzt, der mittels einer Pendelanordnung um eine im wesentlichen horizontale Längsachse schwenkbar bzw. neigbar mit einer ebenso querliegenden Traverse 31 verbunden ist, auf welche ein (nicht dargestellter) Wagenkasten des Schienenfahrzeuges aufsetzbar und befestigbar ist. Die Sekundärfederung mittels Luftfedern 28, 29 besitzt den Vorteil, daß durch deren Regelung die Federwege im wesentlichen nicht lastabhängig sind und dadurch niedrige Steifigkeiten erreicht werden. Für die Realisierung eines möglichst großen Fahrtkomforts, ist ein großes, direkt an die Luftfedern angeschlossenes Luftvolumen unbedingt erforderlich. Bei dem gezeigten Ausführungsbeispiel werden der Innenraum des hohlen Rahmens 2 und der Innenraum des ebenso hohlen Pendelträgers 30 zumindest abschnittsweise in das Volumen der Luftfedern 28, 29 integriert, sodaß eine besonders kompakte Bauweise der Sekundärfederung mit niedriger Bauhöhe erzielt werden kann.At the top of the side members 3, 4 of the frame 2 is in the area of the chassis longitudinal center One air spring 28, 29 is arranged for the secondary suspension of the chassis 1. On the cross Air springs 28, 29 arranged opposite one another is a transverse pendulum support 30 placed on the by means of a pendulum arrangement around a substantially horizontal longitudinal axis is pivotally or inclinably connected to an equally transverse traverse 31 which a (not shown) car body of the rail vehicle can be placed and is attachable. The secondary suspension by means of air springs 28, 29 has the advantage that the regulation of the spring travel is essentially not load-dependent and therefore low Stiffness can be achieved. For realizing the greatest possible driving comfort a large volume of air directly connected to the air springs is absolutely necessary. At the embodiment shown, the interior of the hollow frame 2 and Interior of the equally hollow pendulum support 30 at least in sections in the volume of Air springs 28, 29 integrated, so that a particularly compact design of the secondary suspension can be achieved with a low overall height.

    Der Pendelträger 30 ist bei dem gezeigten Ausführungsbeispiel mit einer aktiven Querfederung und mit einer Wankstabilisierung versehen.The pendulum support 30 is in the embodiment shown with an active cross suspension and provided with roll stabilization.

    Die in Fahrtrichtung sowohl vor als auch hinter dem Pendelträger 30 angeordnete Querfederung ist durch je ein quer angeordnetes aktives Federelement 32, 33 und je ein quer angeordnetes Dämpferelement 34, 35 gebildet, wobei das Federelement 23, 33 seitlich neben dem zugeordneten Dämpferelement 34, 35 angeordnet ist und die nebeneinander angeordneten Elemente 32, 34 bzw. 33, 35 mit ihren einander abgewandten Enden an dem Rahmen 2 des Fahrwerks 1 und mit ihren einander zugewandten Enden im Bereich der Längsmittelebene an einem Verbindungsteil 36, 37 des Pendelträgers 30 abgestützt sind. Das in Fahrtrichtung vor dem Pendelträger 30 angeordnete Querfederelement 32 ist aus Symmetrie- und Stabilitätsgründen an der diagonal gegenüberliegenden Fahrwerksseite wie das dahinter angeordnete Querfederelement 33 vorgesehen. Folglich sind die Dämpferelemente 34, 35 ebenso an diagonal gegenüberliegenden Fahrwerksseiten angeordnet. Die genaue Konstruktion bzw. Steuerung einer Querfederung dieser Art ist dem Fachmann auf dem Gebiet von Drehgestellfahrwerken grundsätzlich bekannt. Im Hinblick auf eine vorteilhafte Steuerung einer Querfederung wird auf die Europäische Patentanmeldung mit der Veröffentlichungsnummer EP-A1-592 387 verwiesen, welche ausdrücklich als ein Teil der vorliegenden Offenbarung anzusehen ist.The one arranged in front of and behind the pendulum support 30 in the direction of travel Cross suspension is by a transversely arranged active spring element 32, 33 and a cross arranged damper element 34, 35 formed, the spring element 23, 33 laterally next to the associated damper element 34, 35 is arranged and the side by side Elements 32, 34 and 33, 35 with their opposite ends on the frame 2 of the Chassis 1 and with their mutually facing ends in the region of the longitudinal median plane a connecting part 36, 37 of the pendulum support 30 are supported. That in the direction of travel the pendulum support 30 arranged cross spring element 32 is made of symmetry and Stability reasons on the diagonally opposite chassis side like that behind arranged transverse spring element 33 is provided. Consequently, the damper elements 34, 35 also arranged on diagonally opposite chassis sides. The exact construction or control of a transverse suspension of this type is the expert in the field of Bogie bogies basically known. With regard to an advantageous control of a Cross suspension is based on the European patent application with the publication number EP-A1-592 387, which is expressly incorporated as part of the present disclosure can be seen.

    Die Wankstabilisierung des Pendelträgers 30 weist zwei quer zum Fahrwerk 1 und symmetrisch zur Fahrwerkslängsmitte angeordnete Torsionsstangen 38, 39 auf, die mit ihren Enden drehbar an den Längsträgern 3, 4 des Rahmens 2 gelagert sind und starr mit je einem im wesentlichen horizontal und in Richtung Pendelträger ausgerichteten Wankstabilisatorhebel 40, 41 verbunden sind, wobei die Stabilisatorhebel 40, 41 mittels nach oben ragenden Zug-Druckstangen 42, 43 gelenkig mit den äußeren Enden des Pendelträgers 30 verbunden sind. Die Elemente der Wankstabilisierung sind sowohl in bezug auf die Fahrwerkslängsmitte als auch in bezug auf die Längsmittelebene des Fahrwerks 1 symmetrisch angeordnet. Dadurch wird jede Wankbewegung des Pendelträgers 30 über die Stangen 42, 43 und die Stabilisatorhebel 40, 41 zu beiden Seiten des Fahrwerks gegensinnig auf die Torsionsstangen 38, 39 übertragen und durch die Torsionswirkung dieser Stangen abgefedert. Zusätzlich zu der Federung der Wankbewegungen des Pendelträgers 30 ist bei einer bevorzugten Ausführungsform des erfindungsgemäßen Drehgestell-Fahrwerks 1 an jeder Seite des Fahrwerks zumindest eine Dämpfeinrichtung 44, 45 vorgesehen, welches die Ausdrehung der Torsionsstangen 38. 39 und somit die Einfederung des Fahrwerks dämpft. Die an jeder Seite einfach vorgesehenen Dämpfeinrichtungen 44, 45 sind bei dem gezeigten Ausführungsbeispiel des Fahrwerks 1 diagonal gegenüberliegend angeordnet.The roll stabilization of the pendulum support 30 has two transverse to the chassis 1 and Arranged symmetrically to the longitudinal center of the torsion bars 38, 39, with their Ends are rotatably mounted on the longitudinal beams 3, 4 of the frame 2 and rigid with one in each roll stabilizer lever 40 oriented essentially horizontally and in the direction of the pendulum support, 41 are connected, wherein the stabilizer levers 40, 41 by means of upward push-push rods 42, 43 are pivotally connected to the outer ends of the pendulum support 30. The elements of roll stabilization are both in relation to the chassis center also arranged symmetrically with respect to the longitudinal center plane of the chassis 1. Thereby each roll movement of the pendulum support 30 over the rods 42, 43 and Stabilizer lever 40, 41 on both sides of the chassis in opposite directions on the torsion bars 38, 39 transmitted and cushioned by the torsion of these rods. In addition to the Suspension of the rolling movements of the pendulum support 30 is preferred Embodiment of the bogie undercarriage 1 according to the invention on each side of the Chassis at least one damping device 44, 45 is provided, which the rotation of the Torsion bars 38. 39 and thus dampens the deflection of the chassis. The one on each side simply provided damping devices 44, 45 are in the embodiment shown of the chassis 1 arranged diagonally opposite.

    Wie in Figur 1 bzw 5 zu sehen ist, ist die Traverse 31 für den Wagenkasten rahmenförmig ausgebildet und weist zwei symmetrisch zur Fahrwerksmitte angeordnete Traversenquerträger 46, 47, die erfindungsgemäß zu beiden Seiten des Pendelträgers 30 und parallel zu diesem angeordnet sind, und je zwei die äußeren Enden der Traversenquerträger 46, 47 verbindende Längsstreben 48, 49 auf. Der Pendelträger 30 ist somit durch die Traverse 31 rahmenförmig umschlossen, sodaß in vorteilhafter Weise eine platzsparende, nämlich sowohl kurze als auch niedrige Konstruktion des Fahrgestells 1 möglich ist. Im Mittelabschnitt weist die Traverse 31 weiters je einen von dem Querträger 46, 47 nach unten ragenden Abschnitt 50, 51 auf wobei die Abschnitte 50, 51 einander konisch zulaufend ausgebildet und an ihren unteren Enden über eine im wesentlichen horizontale Verbindungsplatte 52 miteinander verbunden sind. Somit ist der Pendelträger 30 - bis auf seine Oberseite - durch die Traverse 31 im wesentlichen allseitig umschlossen. Durch die oben beschriebene besondere Konstruktion der Traverse 31 kann diese bei geringem Platzbedarf ausreichend biege- und verwindungssteif gebaut werden.As can be seen in FIGS. 1 and 5, the cross member 31 for the car body is frame-shaped formed and has two cross member arranged symmetrically to the middle of the chassis 46, 47, the invention on both sides of the pendulum support 30 and parallel to this are arranged, and two each connecting the outer ends of the crossmember 46, 47 Longitudinal struts 48, 49. The pendulum support 30 is thus frame-shaped by the cross member 31 enclosed, so that advantageously a space-saving, namely both short and low construction of the chassis 1 is possible. In the middle section, the cross member 31 furthermore each have a section 50, 51 projecting downward from the cross member 46, 47 the sections 50, 51 are tapered and over at their lower ends a substantially horizontal connecting plate 52 are interconnected. So is the pendulum support 30 - except for its top - by the cross member 31 essentially on all sides enclosed. Due to the special construction of the traverse 31 described above, this can can be built to be sufficiently resistant to bending and torsion in a small space.

    Für die Übertragung von Längskräften von dem Fahrgestell 1 auf den Wagenkasten ist an der Verbindungsplatte 52 der Traverse 31 ein nach unten ragender Zapfen 53 angeordnet, der mittels einer sogenannten Lemniskatenführung an dem Fahrwerk geführt und gehalten ist. Die an sich bekannte (in den Figuren nicht dargestellte) Lemniskatenführung des Zapfens 53 weist zwei in Längsrichtung ausgerichtete Längslenker auf, die zu beiden Seiten der Fahrwerkslängsmitte diagonal gegenüberliegend angeordnet und mit ihren der Fahrwerkslängsmitte abgewandten Enden an dem Fahrwerksrahmen angelenkt sind. Die der Fahrwerkslängsmitte zugewandten Enden der Längslenker sind über einen Querlenker gelenkig miteinander verbunden, welcher eine zentrale Bohrung zur Aufnahme des Zapfens 53 aufweist. Zur Abfederung von ruckartig auftretenden Längsbewegungen ist der Zapfen 53 über ein Gummielement in der Bohrung des Querlenkers gehalten. Die Lemniskatenführung ermöglicht eine möglichst direkte Übertragung der Längskräfte von dem Fahrwerksrahmen auf die Traverse. Dennoch ist ein Ausdrehen, ein vertikales Auf- und Abbewegen und ein seitliches Ausschwenken der Traverse bzw des Wagenkastens bezüglich des Rahmens möglich. For the transmission of longitudinal forces from the chassis 1 to the body is on the Connection plate 52 of the cross member 31 a downwardly projecting pin 53 arranged is guided and held on the undercarriage by means of a so-called lemniscate guide. The known lemniscate guide of the pin 53 (not shown in the figures) two longitudinally aligned trailing arms on either side of the Longitudinal center of the chassis arranged diagonally opposite and with their Longitudinal ends remote from the chassis are hinged to the chassis frame. The the Ends of the trailing arms facing the longitudinal center of the chassis are articulated via a wishbone connected to each other, which has a central bore for receiving the pin 53. To cushion jerky longitudinal movements, the pin 53 is a Rubber element held in the hole in the wishbone. The lemniscate tour enables a direct transfer of the longitudinal forces from the chassis frame to the Traverse. Nevertheless, turning out is a vertical movement up and down and sideways Swinging out of the traverse or the car body with respect to the frame possible.

    Die bereits erwähnte schwenkbare Lagerung des Querträgers 31 an dem Pendelträger 30 erfolgt bei dem Fahrwerk 1 der erfindungsgemäßen Art mittels eines Viergelenks, welches durch Pendel 54, 55, 56, 57 realisiert ist, wobei je zwei Pendel 54, 56 bzw. 55, 57 in Längsrichtung in einem Abstand hintereinander angeordnet sind und die gegenüberliegend angeordneten Pendel 54, 55 bzw. 56, 57 symmetrisch zur Längsmittelebene trapezförmig angeordnet sind. Die Pendel 54, 55, 56, 57 sind an ihren oberen Enden mittels je eines Bolzens an dem Pendelträger 30 und an ihren unteren Enden mittels je eines Bolzens an der Verbindungsplatte 52 der Traverse 31 angelenkt.The aforementioned pivotable mounting of the cross member 31 on the pendulum support 30 takes place in the chassis 1 of the type according to the invention by means of a four-bar linkage, which is realized by pendulums 54, 55, 56, 57, two pendulums 54, 56 and 55, 57 in Longitudinal direction are arranged one behind the other and the opposite arranged pendulums 54, 55 and 56, 57 symmetrical to the longitudinal median plane trapezoidal are arranged.

    In Figur 6 ist die Anlenkung des Pendels 55 an dem Pendelträger 30 und der Traverse 31 im Detail dargestellt. Hiefür sind sowohl an dem Pendelträger 30 als auch an der Traverse 31 seitliche Bohrungen 58, 59 vorgesehen, die mit Schlitzen 60, 61 für das Pendel 55 durchsetzt sind. Das Pendel 55 ist durch mehrere, z.B. vier Federstahlplatten 62a, 62b, 62c, 62d gebildet, die flächig aneinandergefügt sind und im Bereich ihrer oberen und unteren Enden durch je zwei Bolzen 65, 66 miteinander verbunden sind. Der Vorteil dieser Konstruktion liegt unter andrem darin, daß die Federplatten 62a, 62b, 62c, 62d in ihrer Längsrichtung (vertikal) eine hohe Zugfestigkeit besitzen, quer zu ihrer Längsrichtung (in Fahrtrichtung) jedoch eine hohe Elastizität aufweisen, sodaß eine genau definierte Neigestellung der Traverse bezüglich des Pendelträgers erfolgen kann, in Längsrichtung jedoch eine gewisse Elastizität zum Ausgleich von Bewegungen innerhalb vorhandener Spiele oder Toleranzen ermöglicht wird. Durch die hohe Zugfestigkeit dieser Pendel können sie besonders platzsparend untergebracht werden. Wie bereits erwähnt, erfolgt die Anlenkung der beiden Enden des Pendels 55 mittels je eines Bolzens 65, 66, welcher in der zugeordneten Bohrung 58, 59 in je einem Gleitlager paßgenau gelagert ist. Alternativ zu einem Gleitlager kann im Rahmen der vorliegenden Erfindung zur Lagerung der Bolzen 65, 66 auch ein Wälzlager verwendet werden. Zur Erleichterung des Zusammenbaus sind die Bolzen 65, 66 bei dem gezeigten Ausführungsbeispiel zweiteilig ausgebildet, wobei die zwei ineinandersteckbaren Teile mittels Schrauben miteinander verbindbar sind.In Figure 6, the articulation of the pendulum 55 on the pendulum support 30 and the cross member 31 in Detail shown. For this purpose, both on the pendulum support 30 and on the cross member 31 lateral bores 58, 59 are provided, which pass through with slots 60, 61 for the pendulum 55 are. The pendulum 55 is divided by several, e.g. four spring steel plates 62a, 62b, 62c, 62d are formed, which are joined together flatly and in the area of their upper and lower ends by two each Bolts 65, 66 are interconnected. The advantage of this construction lies among others in that the spring plates 62a, 62b, 62c, 62d are high in their longitudinal direction (vertical) Have tensile strength, but high across their longitudinal direction (in the direction of travel) Have elasticity, so that a precisely defined inclination of the crossbar with respect to the Pendulum carrier can take place, but in the longitudinal direction a certain elasticity to compensate of movements within existing games or tolerances. Through the high tensile strength of these pendulums, they can be accommodated in a particularly space-saving manner. As already mentioned, the two ends of the pendulum 55 are articulated by means of one each Bolt 65, 66, which fits in the associated bore 58, 59 in a slide bearing is stored. As an alternative to a plain bearing, for the purposes of the present invention Storage of the bolts 65, 66 also a roller bearing can be used. To facilitate the Assembly bolts 65, 66 are in two parts in the embodiment shown formed, the two nested parts by means of screws together are connectable.

    Bei Verschwenken der Traverse 31 bezüglich des Pendelträgers 30 sind diese in Richtung quer zur Fahrtrichtung aneinander erfindungsgemäß geführt und abgestützt. Bei dem vorliegenden Ausführungsbeispiel ist diese Führung einerseits durch Reibplatten 67, 68, 69, 70, die zu beiden Seiten des Pendelträgers 30 in einem Abstand von der Längsmittelebene und symmetrisch zu dieser angeordnet sind, andererseits durch Gleitflächen 71, 72, 73, 74 der Traverse 31 gebildet, die den Reibplatten 67, 68, 69, 70 gegenüberliegend an den zugeordneten Traversenquerträgern 46, 47 angeordnet sind. Die genaue Ausgestaltung und Anordnung der Reibplatte 67 bzw. der Gleitfläche 71 gemäß dem Ausführungsbeispiel ist in Figur 6 zu sehen. Die Reibplatte 67 ist in einem Haltestück 75 aufgenommen, welches in die Bohrung 58 für die Pendellagerung eingesetzt und darin befestigt ist. Die Gleitfläche 71 hingegen wird durch einen der Reibplatte 67 zugewandten Teilabschnitt des konisch nach unten ragenden Abschnittes 50 der Traverse 31 gebildet.When the cross member 31 is pivoted with respect to the pendulum support 30, these are transverse in the direction guided and supported against each other according to the invention in the direction of travel. In the present Exemplary embodiment is this guide on the one hand by friction plates 67, 68, 69, 70 which too both sides of the pendulum support 30 at a distance from the longitudinal median plane and are arranged symmetrically to this, on the other hand by sliding surfaces 71, 72, 73, 74 of Traverse 31 formed, the friction plates 67, 68, 69, 70 opposite to the assigned crossbeams 46, 47 are arranged. The exact design and The arrangement of the friction plate 67 or the sliding surface 71 according to the exemplary embodiment is shown in FIG Figure 6 can be seen.

    Durch die weiter oben beschriebene und in den Figuren dargestellte Pendellagerung liegt die momentane Schwenkachse bei Neigung der Traverse 31 bezüglich des Pendelträgers 30 üblicherweise im Bereich oberhalb des Wagenschwerpunktes. Im ungeneigten Ruhezustand liegt die Schwenkachse in der Längsmittelebene des Wagens, wogegen die Schwenkachse sich bei Neigen der Traverse von der Längsmittelebene des Wagens entfernt. Durch die von dem Wagenschwerpunkt entfernte Lage der momentanen Schwenkachse im geneigten Zustand der Traverse wird jedoch ein bestimmtes Rückstellmoment erzeugt, welches den Wagen bzw. die Traverse automatisch wieder in ihre Ausgangslage zurückbewegt, bzw. dieses Zurückbewegen unterstützt, sodaß hierdurch eine passive Neigungs-Rückstellung des Wagenkastens möglich ist.Due to the self-aligning described above and shown in the figures, the instantaneous pivot axis when the cross member 31 is inclined with respect to the pendulum support 30 usually in the area above the center of gravity. In the non-inclined state of rest the swivel axis lies in the longitudinal median plane of the carriage, whereas the swivel axis is opposite away from the longitudinal median plane of the carriage when the traverse is inclined. Because of that Center of gravity distant position of the current swivel axis in the inclined state of the However, a specific restoring moment is generated by the crossbeam, which the carriage or the Traverse automatically moves back to its starting position, or move this back supported so that a passive inclination reset of the car body is possible is.

Durch die besonders tiefliegende Anordnung der Stelleinheit 76 befinden sich die Krafleinleitungspunkte in einem vergleichsweise großen Abstand von dem Wagenschwerpunkt, sodaß die Neigungsstellung unter geringem Krafteinsatz möglich ist. Dies wirkt sich besonders vorteilhaft auf die Dimensionierung und die Lebensdauer der gesamten Neigestellmechanik (Stelleinheit, Lagerstellen, Bolzen u.s.w.) aus. Weiters ist die gesamte Neigestellmechanik erfindungsgemäß über die Sekundärfederstufe (Luftfedern 28, 29) an dem Fahrwerksrahmen abgestützt, sodaß die Mechanik von dem Fahrwerk im wesentlichen keine Erschütterungen oder Stöße aufnehmen bzw. übertragen muß.
