Schienenfahrzeugtrack vehicle

Die Erfindung betrifft ein Schienenfahrzeug mit einem Fahrwerk, das über an Achsenträger angeordnete einzelne Räder verfügt, die jeweils in horizontaler Richtung um eine vertikale Lenkachse schwenkbar gelagert sind, mit einem jeweils den Rädern zugeordneten Lenkaktor zur Einstellung eines vorgegebenen Lenkwinkels um die vertikale Lenkachse.The invention relates to a rail vehicle with a chassis that has arranged on axle carrier individual wheels, which are each mounted pivotably about a vertical steering axis in the horizontal direction, with a respective steering wheels associated with the steering actuator for setting a predetermined steering angle about the vertical steering axis.

Aus der DE 40 40 303 Al ist ein Schienenfahrzeug mit einem Fahrwerk bekannt, das über Achsenträger mit einzelnen Rädern verfügt, die jeweils in horizontaler Richtung um eine vertikale Lenkachse schwenkbar gelagert sind. Die Räder wirken mit einem Lenkaktuator zusammen, so dass die Räder während der Fahrt entsprechend einem vorgegebenen Lenkwinkel eingestellt werden können. Das Schienenfahrzeug verfügt über ein Einzelradfahrwerk und kann durch Beaufschlagung der Räder durch den Lenkaktor aktiv gelenkt werden.From DE 40 40 303 Al a rail vehicle with a chassis is known, which has axle holders with individual wheels, which are each mounted pivotably about a vertical steering axis in the horizontal direction. The wheels cooperate with a steering actuator, so that the wheels can be adjusted while driving according to a predetermined steering angle. The rail vehicle has a Einzelradfahrwerk and can be actively steered by applying the wheels through the steering actuator.

Nachteilig an dem bekannten Schienenfahrzeug ist, dass die Spurführung und Spurlenkung beim Befahren von Kurven bzw. von passiven Weichen nicht zuverlässig gewährleistet ist und bei ungünstigen Bedingungen zum Entgleisen der Schienenfahrzeuge führen kann. Aufgabe der vorliegenden Erfindung ist es daher, ein Schienenfahrzeug derart weiterzubilden, dass eine sichere, zuverlässige und robuste Spurführung desselben gewährleistet ist.A disadvantage of the known rail vehicle is that the tracking and steering is not reliably ensured when driving on bends or passive switches and can lead to derailment of rail vehicles under unfavorable conditions. Object of the present invention is therefore to develop a rail vehicle such that a secure, reliable and robust tracking of the same is ensured.

Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff von Anspruch 1 dadurch gelöst, dass die Räder der Achse jeweils in vertikaler Richtung schwenkbar um eine horizontale Sturzachse gelagert und mittels eines Sturzaktors beaufschlagbar sind zur Einstellung eines vorgegebenen Sturzwinkels .To solve this problem, the invention is achieved in conjunction with the preamble of claim 1, characterized in that the wheels of the axle are each mounted in the vertical direction pivotable about a horizontal camber axis and acted upon by a fall actuator for setting a predetermined camber angle.

Der besondere Vorteil der Erfindung besteht darin, dass eine zuverlässige und robuste Spurführung und Spurlenkung ermöglicht wird, die unabhängig vom Reibbeiwert eines Rad- Schienen-Kontaktpunktes ist. Sinkt beispielsweise der Reibbeiwert infolge von Witterung, wie Eis oder Laub auf den Schienen, muss nicht die Fahrzeuggeschwindigkeit in der Kurve reduziert werden.The particular advantage of the invention is that a reliable and robust tracking and steering is made possible, which is independent of the coefficient of friction of a wheel-rail contact point. If, for example, the coefficient of friction drops due to weather conditions, such as ice or leaves on the rails, the vehicle speed in the curve does not have to be reduced.

Grundgedanke der Erfindung ist es, die Abhängigkeit der Spurführungskräfte von der Reibung zu entkoppeln. Erfindungsgemäß erfolgt dies dadurch, dass der Sturz der Räder geändert wird bzw. diese seitlich zur Fahrzeuglängsachse geneigt werden. Dadurch, dass die Schienen ein balliges Querschnittsprofil aufweisen, können sich die Räder an diesem abstützen.The basic idea of the invention is to decouple the dependence of the tracking forces on the friction. According to the invention, this is done by changing the camber of the wheels or tilting them laterally relative to the vehicle's longitudinal axis. The fact that the rails have a spherical cross-sectional profile, the wheels can be supported on this.

Nach einer bevorzugten Ausführungsform der Erfindung wird ein Sturzaktor derart angesteuert, dass sich das Rad in einer Mittelstellung oder Sturzstellung befindet, in der im Radaufstandspunkt ausschließlich Normalkräfte übertragen werden. Das Rad wird somit derart seitlich geneigt, dass in Querrichtung keine Reibkraft wirkt. Hierdurch können bei einer Kurvenfahrt auftretende Querbeschleunigungen vollständig über Profilseitenkräfte abgestützt werden. Der Verschleiß im Rad-Schienen-Kontaktpunkt kann verringert werden. Eine Schlupffreiheit in Querrichtung kann gewährleistet werden.According to a preferred embodiment of the invention, a fall actuator is controlled such that the wheel is in a middle position or fall position in which only normal forces are transmitted in Radaufstandspunkt. The wheel is thus inclined laterally, that no frictional force acts in the transverse direction. As a result, lateral accelerations occurring during cornering can be fully supported via profile lateral forces. The wear in the wheel-rail contact point can be reduced. Slip freedom in the transverse direction can be ensured.

Nach einer Weiterbildung der Erfindung ist das Rad über eine Viergelenkkette in dem Fahrwerk gelagert. Vorteilhaft können hierdurch unerwünschte Bewegungen des Fahrwerks vermieden werden. Hierbei wird der Abstand zwischen einem Momentanpol und dem Rad-Schienen-Kontaktpunkt (Radauf- Standspunkt) gering gehalten.According to a development of the invention, the wheel is mounted on a four-bar chain in the chassis. Advantageously, this unwanted movements of the chassis can be avoided. Here, the distance between a current pole and the wheel-rail contact point (Radauf- point) is kept low.

Nach einer Weiterbildung der Erfindung ist das Rad mittels einer Achsschenkellenkung in dem Fahrwerk gelagert.According to a development of the invention, the wheel is mounted by means of a steering knuckle in the chassis.

Nach einer besonderen Ausführungsform der Erfindung kann eine feste Sturzachse pro Rad vorgesehen sein, die sich senkrecht zur Lenkachse und parallel zur Fahrzeuglängsrichtung erstreckt.According to a particular embodiment of the invention, a fixed camber axle may be provided per wheel, which extends perpendicular to the steering axis and parallel to the vehicle longitudinal direction.

Nach einer zweiten Ausführungsform der Erfindung kann die Sturzachse auch in Abhängigkeit vom Sturzwinkel veränderbar sein. Hierbei ist das Rad über Querlenker mit einem Achsträger gekoppelt.According to a second embodiment of the invention, the camber axis can also be changed depending on the camber angle. Here, the wheel is coupled via wishbones with an axle.

Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention will become apparent from the further subclaims.

As can be seen from the camber position of the wheel 1 shown in FIG. 3, the camber angle αs of the wheel 1 corresponds to the angle (XF) resulting from the vertical force Fv and the vertical force Fv and the transverse force FQ Force FR is included.
