Definitions

  • the invention relates to a wheel module, in particular for motor vehicles.
  • the motor vehicle With the help of the wheel module, the motor vehicle can be steered and/or driven and/or braked and/or damped with the help of a spring/damper unit.
  • a motor vehicle with a wheel module is known from CN 206679065 U, in which a wheel of the wheel module can be rotated by 90° about a vertical steering axis in order to be able to park the motor vehicle in tight parking spaces.
  • a wheel module for a motor vehicle in particular a multi-track passenger car, with a wheel for moving the motor vehicle, a trailing arm that can be connected to a supporting frame of the motor vehicle, a steering element rotatably mounted with the trailing arm via a first bearing element, the steering element having a first Having steering section and a second steering section, the first steering section forming a first bearing point at one of its distal ends with the first bearing element, said first bearing point being arranged close to a substrate.
  • the wheel module according to the invention for a motor vehicle comprises a wheel that can be rotated about a center of rotation for moving the motor vehicle and a trailing arm that can be attached to a supporting frame of the motor vehicle in an articulated manner about a pivot axis for supporting forces acting on the wheel on the supporting frame.
  • the trailing arm is connected to the steering element via a first bearing point close to the ground. Close to the ground means that the attachment or connection of these two components in a vertical direction (z-axis) is provided as far down as possible, i.e. not above the wheel in the z-direction.
  • the surface or roadway on which the motor vehicle moves or is parked is referred to as the subsoil.
  • the trailing arm allows the wheel to move in and out, and the steering element ensures the rotational movement or steering movement of the wheel about a steering axis.
  • the steering element is rotatably mounted in the trailing arm. This has the advantage that there is no need for a massive connection above the wheel, which means that weight and installation space can be reduced while at the same time ensuring the required steering angle.
  • An X-direction is understood to mean a coordinate direction along a longitudinal axis of a motor vehicle when the wheel module is installed in the motor vehicle.
  • the X-direction runs essentially horizontally when the motor vehicle is parked on a flat, horizontally running surface.
  • the first steering section and the second steering section are preferably connected to one another at a central connection point and this central connection point is connected to the wheel. Such a connection enables the wheel to be steered by means of the steering element
  • one of the distal ends of the second steering section forms a second bearing point with a second bearing element.
  • the second bearing point is located away from the ground, i.e. the connection is provided above the wheel or at least above the center of the wheel.
  • the steering element is preferably connected to the trailing arm by means of the second bearing element.
  • the steering element enables a low disturbance force lever arm, since a puncture point of the steering axle can be placed at ground level near the center of the wheel.
  • the position of the puncture point of the steering axle and the position of the steering axle as a whole is determined by the steering element and, as already described, by means of the two bearing points.
  • a shock absorber which acts on the trailing arm and can be supported on the supporting frame of the motor vehicle is provided for damping vibrations of the wheel caused by unevenness in the roadway.
  • the shock absorber can impress a sufficient contact force for the wheel and dampen vibrations of the wheel caused by bumps in the road. These vibrations of the wheel can be followed by the trailing link due to the articulated support of the trailing link.
  • the force direction of the shock absorber is preferably aligned predominantly in the Z-direction. As a result, the shock absorber can predominantly support the forces occurring in the Z direction, while the trailing arm can predominantly support the forces occurring in the X and Y directions. With low transverse loads in the shock absorber and the trailing arm, the forces that occur can be well supported with a small use of material and small space requirements. As a result, further supporting components are not required and can be saved, as a result of which the space requirement and the production costs can be kept low.
  • One embodiment relates to a motor vehicle with a support frame and wheel modules supported on the support frame, which can be designed and developed as described above, for steering the motor vehicle, with each wheel module enabling the wheel to be steered by at least 90°. Due to the large steering angle that is made possible, it is possible for the motor vehicle to drive transversely to the direction of travel and/or to turn on the spot.
  • the design of the wheel module mentioned can be articulated particularly close to the ground with a lower use of material and a lower installation space requirement with a favorable lever arm for supporting transverse forces acting on the wheel, so that a space-saving motor vehicle is made possible.
  • FIG. 1 shows a schematic top view of a wheel module of the motor vehicle at different steering angles
  • FIG. 2 shows a schematic view of the wheel module.
  • the motor vehicle 2 has a support frame 3 that is in particular essentially rectangular.
  • a wheel module 1 supported directly or indirectly on the support frame is fastened to each of the corners of the support frame.
  • the wheel module 1 has a rotatable wheel 4 that can be steered using a steering actuator. Bumps in the road can be dampened by a shock absorber 5 acting on the wheel 4 .
  • the wheel module 1 can be turned through more than 90° at least in one steering direction.
  • the motor vehicle 2 can also drive transversely to the direction of travel and/or turn on the spot.
  • each wheel 4 of the respective wheel module can be controlled and driven individually, so that a specific steering angle and a specific direction of rotation can be specified individually for each wheel 4 in order to realize a correspondingly large number of motor vehicles.
  • the wheel 4 can be deflected from a position for straight-ahead travel by at least 90°, in particular approximately 95°, in one direction of rotation and by approximately 40° in the other direction of rotation.
  • Figure 2 shows the wheel module 1 in more detail.
  • Bumps in the roadway can be dampened by a shock absorber 5 acting on the wheel 4, the shock absorber 5 for supporting forces occurring in the Z direction on the wheel 4 above the wheel 4 being at least indirectly on the support frame 3 is supported.
  • a trailing arm 6 that can be connected in an articulated manner is provided about a pivot axis to support forces acting on the wheel 4 .
  • the trailing arm 6 is connected to a steering element 7, which is connected via a first bearing point 8 by means of a first bearing element 14 close to the ground. Close to the ground means that the attachment or connection of these two components is provided as far down as possible in a vertical direction (z-axis), ie not above the wheel 4 in the z-direction.
