Abstract
A wheel suspension, in particular an independent wheel suspension, having active adjustment of the wheel camber. An intermediate carrier is arranged between the hub carrier holding the wheel and the body-side wheel suspension, in particular the wheel suspension links. The intermediate carrier is linked to the wheel suspension on the body side and has a pivot axis running in the longitudinal direction of the vehicle.
Claims9
A suspension system for a wheel of a motor vehicle, the wheel suspension system comprising:
- at least one body-side wheel suspension member;
- a hub carrier including an axle end holding the wheel and defining a pivot axis, the pivot axis being disposed in the vehicle longitudinal direction and being vertically offset from a rotational axis of the wheel, the hub carrier being capable of pivoting to set a negative camber of the wheel on an order of magnitude of about 20-30 degrees so that a tread contact surface of a tire of the wheel is moved to a tread area of the tire that is adjacent to an inside of the wheel;
- an intermediate carrier disposed between the body-side wheel suspension member and the hub carrier, the hub carrier being capable of pivoting on the intermediate carrier about the pivot axis;
- and
- an actuator acting in a transverse direction of the vehicle for active adjustment of the camber of the wheel with reference to the pivot axis, the actuator supporting the hub carrier against the intermediate carrier;
- wherein the body-side wheel suspension member includes a rigid axle body.
