Abstract: A wheel suspension for a motor vehicle has a transverse control arm that can be attached to a vehicle body by way of bearings and a spring-elastic torsion bar assembly, and can be rotated about a longitudinal axis. The torsion bar assembly has a body spring that can be attached to the vehicle body with one end, and a transverse control arm spring that is attached to the transverse control arm with one end. The body spring and the transverse control arm spring are coupled with one another at their free ends. The transverse control arm spring and the body spring are coupled with one another by way of a setting element or a releasable connection, whereby the setting element or the releasable connection, respectively, allows rotation of the ends assigned to one another, for setting purposes.

Abstract: A wheel suspension for a motor vehicle has a transverse control arm that can be attached to a vehicle body by way of bearings and can be rotated about a longitudinal axis, and a body spring configured as a torsion bar spring for absorbing rotational movements of the transverse control arm about the longitudinal axis. The body spring is disposed on the transverse control arm so as to rotate with it, with a first end. An electromechanical actuator for changing the angle of rotation of the body spring is disposed at a second end of the body spring. The wheel suspension has a damping element. The second end of the body spring is connected with a stress relief spring that is configured as a torsion bar spring, disposed coaxially with the body spring, and can be attached to the vehicle body.

Abstract: A vibration damper having a sensitive response behavior at very low amplitudes comprises a separating piston being disposed inside a bypass so as to move axially freely. The separating piston divides the bypass into two chambers mutually sealed from one another. Two valves are disposed in the bypass. The first valve acts in a compression stage as a pressure limiting valve and as a non return valve in an extension stage. The second valve acts as a pressure limiting valve in the extension stage and as a non return valve in the compression stage.

Abstract: The invention relates to a vibration damper having an amplitude-selective damping device, comprising a damper tube (1) which is filled with damping fluid and in which a piston rod (2) is disposed in such a manner as to be able to move in a reciprocating manner, said piston rod supporting a damping piston (5) which divides the inner space of the damper tube (1) into a piston rod-side working chamber (3) and a working chamber (4) remote from the piston rod, a space (6) to receive damping fluid, which space is disposed inside a bypass provided between the working chambers (3, 4) and hydraulically in parallel with the damping piston (5) and in which an axially moveable separating piston (7) is disposed which divides the space (6) into a piston rod-side chamber (8) and a chamber (9) remote from the piston rod, wherein the bypass comprises at least a first hydraulic connection channel (10), via which the piston rod-side working chamber (3) is connected to the piston rod-side chamber (8), and at least a second
