A spring and damper system, in particular for an assembly mount in a motor vehicle, includes a spring/damper element arranged between two mutually, relatively displaceable vehicle masses, wherein the spring/damper element includes a damper device and a positioning spring element, which are directly or indirectly coupled with one another and are connected in series and which are supported on or attached to a respective vehicle mass. A progressive spring element forms an additional component of the spring/damper element, wherein the progressive spring element is arranged on a side of the positioning spring element facing away from the damper device and is directly or indirectly connected to the damper device or to the vehicle mass facing the positioning spring element. The progressive spring element has a defined gap spacing representing a spring deflection in a defined rest position.

A wheel suspension for a rear wheel of a motor vehicle includes a wheel carrier, a lower control arm and a track rod connected to the wheel carrier at first and second points of articulation and supported on a vehicle body by first and second bearings. A rotation movement by the control arm and the track rod in response to longitudinal and/or lateral forces causes a toe-in change to thereby adjust the first point of articulation of the control arm by a first transverse offset in a vehicle transverse direction and adjust the second point of articulation of the track rod by a second transverse offset in the vehicle transverse direction. The first bearing is configured elastokinematically such that the first transverse offset of the first point of articulation is greater than the second transverse offset of the second point of articulation in response to the longitudinal and/or lateral forces.

The invention relates to a method for damping vibrations on chassis bearings of motor vehicles, and a device for implementing the process. A process and a device are to be presented with which outstanding vibration damping and vibration isolation and noise insulation can be achieved over a wide frequency range with consideration of the driving states and roadway conditions which occur in motor vehicles. For this purpose it is proposed that the driving state of the motor vehicle and/or the roadway conditions are detected by way of sensors and that the at least one chassis bearing is modified to different characteristics to change its stiffness and/or damping depending on the detected parameters. The device is formed with sensors for detecting the driving state of the motor vehicle and for roadway conditions, with an electronic control device for processing the acquired signals and for selection of various controllable characteristics and at least one chassis bearing, the stiffness and/or damping of which can be modified.
