Definitions

  • the invention relates to a rail vehicle comprising a chassis provided with individual wheels which are respectively mounted on axle carriers in such a way that they can pivot in the horizontal direction about a vertical steering axis.
  • Said rail vehicle also comprises a steering actuator associated with each wheel, for adjusting a pre-determined steering angle about the vertical steering axis.
  • DE 40 40 303 A1 discloses a rail vehicle with a chassis, of which individual wheels are mounted on an axle carrier, which is mounted for pivoting in the horizontal direction about a vertical steering axis.
  • the wheels cooperate with a steering actuator, so that the wheels during travel can be adjusted to a predetermined steering angle.
  • the rail vehicle includes an independent-wheel running gear and can be actively steered by actuation of the steering actuator on the wheels.
  • the solution of this task is solved thereby, that the wheels of the axle are respectively mounted in such a way that they can be pivoted in the vertical direction about a horizontal camber axis and can be actuated by means of a camber actuator for adjusting the predetermined camber angle.
  • the particular advantage of the invention is comprised therein, that a reliable and robust rail guidance and rail steering is made possible, which is independent of the coefficient of friction of a wheel-rail-contact point. If the coefficient of friction drops due to weather conditions, such as ice or foliage on the rails, then the rail vehicle speed need not be reduced in the curve.
  • a camber actuator is controlled in such a manner, that the wheel is oriented in a central position or camber position, in that exclusively normal forces are transmitted in the wheel contact point.
  • the wheel is thus tilted sideways in such a manner that no frictional forces exist in the transverse direction.
  • transverse forces occurring during negotiation of a curve can be completely supported via the sideways forces on the contoured sides.
  • the friction at the wheel-to-rail-contact point can be reduced. An absence of slippage in the transverse direction can be ensured.
  • the wheel is mounted via a four-bar linkage to the chassis.
  • Advantageously thereby undesired movements of the chassis can be avoided.
  • the space between the instantaneous center of rotation and the wheel-to-rail contact point can be kept small.
  • the wheel is mounted to the chassis via a king-pin steering.
  • one fixed camber axis per wheel can be provided, which is oriented perpendicular to the steering axis and parallel to the vehicle longitudinal direction.
  • the camber axis can be variable depending on the camber angle.
  • the wheel is coupled to the axle carrier via a cross linkage or control arm or wishbone.
  • FIG. 1 a a schematic vertical section through a chassis of a rail vehicle according to a first embodiment
  • FIG. 1 b a horizontal section through the chassis according to the first embodiment
  • FIG. 2 a a schematic vertical section through a chassis according to a second embodiment
  • FIG. 2 b a horizontal section through the chassis of the second embodiment
  • FIG. 3 a schematic representation of a camber position of the wheel.
  • a rail vehicle is moved along the rails 4 by a not shown drive and/or braking unit in the vehicle in the longitudinal direction (transverse to the image plane according to FIG. 1 a ) with rolling of the wheels 1 .
  • the wheels 1 are a component of a chassis 2 , which is provided in a not-shown rail carriage body.
  • the chassis 2 includes elongate axle carriers 3 , upon the opposite end areas of which the wheels 1 are respectively individually mounted.
  • a steering actuator 5 For adjusting to a predetermined steering angle ⁇ L about a vertical steering axis V a steering actuator 5 is provided.
  • the steering actuator 5 is mounted between an arm 6 and the not-shown wheel hub provided in the wheel 1 .
  • the vertical steering axis V extends in a central radial plane M R of the wheel 1 .
  • the steering actuator 5 is controlled via a not shown control unit in such a manner, that the wheel 1 is adjusted according to such a steering angle ⁇ L , that the wheels 1 are guided along one of the curve radius r set by the rails 4 .
  • a camber actuator 7 is provided, which is provided between the axle arm 8 and the axle carrier 3 .
  • the wheel 1 is pivotable about a fixed horizontal camber axis S, which runs at a vertical height, which is set below a horizontal axle plane of the wheel 1 .
  • the camber actuator 7 engages above the horizontal axial plane of the wheel 1 .
  • the camber axis S is provided 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 central radial plane M R of the wheel 1 .
  • the camber actuator 7 is controlled via a not shown control unit in such a manner, that the wheel 1 is pivoted, depending upon the longitudinal angle ⁇ L , in such a way about the camber angle ⁇ S sideways of the central position in a camber position, so that at the wheel contact point P exclusively normal forces F N are transmitted.
  • the camber angle ⁇ S of the wheel 1 corresponds to the angle ⁇ F , which is locked in or implemented on the one hand by the vertical force F V and on the other hand by the force F R resulting from the combination of the vertical force F V and the transverse force F Q .
  • the camber actuator 7 can be controlled during negotiating of a curve in such a manner, that the camber angle ⁇ S is computed from the relationship
  • the camber actuator 7 is connected via a twin control arm or suspension arm 9 of a control arm or suspension arm unit 10 with the wheel 1 in an articulated linkage.
  • a twin control arm or suspension arm 9 of a control arm or suspension arm unit 10 with the wheel 1 in an articulated linkage.
  • the control arm unit 10 is comprised of two twin control arms 9 , 9 ′, which extend from a common axle arm 11 on both sides of the central radial plane M R of the wheel 1 .
  • a tilting of the wheel 1 about a variable camber axis S occurs. This is preferably situated below a horizontal axial plane of the wheel 1 .
  • the twin control arms 9 or, as the case may be, 9 ′ exhibit respectively parallel control arm axis 12 .
  • the steering actuator 5 is mounted between a steering rod 13 and the not shown wheel hub provided in the wheel 1 .
  • the wheel 1 can be mounted in the chassis 2 via a four-bar linkage.
  • the wheel 1 is mounted in the chassis 2 via a king-pin steering.
  • the vertical steering axis V preferably runs in the central radial plane M R of the wheel 1 .
