Abstract
A wheel suspension for a two-track motor vehicle includes a multi-link assembly having control arms that are articulated on a vehicle body and on a wheel carrier, a rotary actuator for an active suspension control system, with a motor-gear-unit constructed to transfer torques as actuating forces to the multi-link assembly via a torsion rod, and at least one reinforcing brace independent of the multi-link assembly and disposed on a side of the vehicle body and extending below the multi-link assembly, as viewed in a vertical direction of the vehicle body. The reinforcing brace delimits downwardly in the vehicle's vertical direction a free space, in which the rotary actuator is at least partially arranged.
Claims20
A wheel suspension for a two-track motor vehicle, comprising
- a multi-link assembly comprising control arms which are articulated on a vehicle body and on a wheel carrier,
- a rotary actuator for an active suspension control system, comprising a motor-gear-unit constructed to transfer torques as actuating forces to the multi-link assembly via a torsion rod, said torsion rod oriented substantially in a transverse direction of the motor vehicle, and
- at least one reinforcing brace independent of the multi-link assembly and extending in alignment with the torsion rod below the multi-link assembly, as viewed in a vertical direction of the vehicle body, wherein a first end of the at least one reinforcing brace is attached at a first location on a side of the vehicle body and a second end of the at least one reinforcing brace is attached at a different second location of the vehicle body, with the at least one reinforcing brace defining a lower boundary of a free space downwardly in the vehicle's vertical direction, in which free space the rotary actuator is at least partially arranged.
