Definitions
- 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.
- a rail vehicle with a chassis 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 Einzelradfahrtechnik and can be actively steered by applying the wheels through the steering actuator.
- 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.
- 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.
- 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.
- 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.
- 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 Radaufstandsyak.
- the wheel is thus inclined laterally, that no frictional force acts in the transverse direction.
- 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.
- the wheel is mounted on a four-bar chain in the chassis.
- this unwanted movements of the chassis can be avoided.
- the distance between a current pole and the wheel-rail contact point (Radauf- point) is kept low.
- the wheel is mounted by means of a steering knuckle in the chassis.
- a fixed camber axle may be provided per wheel, which extends perpendicular to the steering axis and parallel to the vehicle longitudinal direction.
- the camber axis can also be changed depending on the camber angle.
- the wheel is coupled via wishbones with an axle.
- FIG. 1a is a schematic vertical section through a chassis of a rail vehicle according to a first embodiment
- FIG. 1b a horizontal section through the chassis according to the first embodiment
- FIG. 2a shows a schematic vertical section through a chassis according to a second embodiment
- Figure 2b a horizontal section through the chassis of the second embodiment
- Figure 3 a schematic representation of a fall position of the wheel.
- a rail vehicle is moved by a not shown drive and / or brake unit in the vehicle longitudinal direction (transversely to the sheet plane of Figure Ia) under rolling wheels 1 on the rails 4.
- the wheels 1 are part of a chassis 2, which is arranged in a carriage body, not shown.
- the chassis 2 includes elongated axle 3, at the opposite end portions of the wheels 1 are each stored individually.
- a steering actuator 5 For setting a predetermined steering angle CXL about a vertical steering axis V, a steering actuator 5 is provided. Of the Lenkaktor 5 is mounted between a Achsarm 6 and the wheel hub, not shown, and mounted in the wheel 1. The vertical steering axis V extends in a middle radial plane MR of the wheel 1.
- the steering actuator 5 is controlled by means of a control unit, not shown, such that the wheels 1 of an axle carrier 3 are adjusted according to such a steering angle ⁇ X L , that the wheels 1 are moved along a given by the rails 4 curve radius r.
- a fall actuator 7 is provided, which is mounted between an axle arm 8 and the axle carrier 3.
- the wheel 1 is pivotable about a fixed horizontal camber axis S, which runs in a vertical height, which is arranged below a horizontal axial plane of the wheel 1.
- the fall actuator 7 engages above the horizontal axial plane of the wheel 1.
- the camber axis S is arranged perpendicular to the vertical longitudinal axis V and in the vehicle longitudinal direction.
- the horizontal camber axis S and the vertical longitudinal axis V intersect in the middle radial plane MR of the wheel 1.
- the fall actuator 7 is controlled by means of a control unit, not shown, such that the wheel 1 is pivoted laterally out of the middle position into a fall position as a function of the longitudinal angle (XL) by the camber angle cts. finally normal forces FN are transmitted.
- the camber angle ⁇ s 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.
- the fall actuator 7 is connected to the wheel via a twin wishbone 9 of a transverse link unit 10
- the transverse link unit 10 consists of two twin wishbones 9, 9 ', extending from a common Achsarm
- the wheel 1 can be mounted in the chassis 2 via a four-bar chain.
- the wheel 1 is mounted in the chassis 2 by means of a stub axle steering.
- the vertical steering axis V preferably runs in the middle radial plane MR of the wheel 1.
