Strut For A Motor Vehicle With An Axially Adjustable Spring Plate

Strut for a motor vehicle with an axially adjustable spring plate comprising

• a vibration damper with a cylinder and a piston rod which is supported to be able to move axially therein,
• a support spring which is dynamically connected to the axially adjustable spring plate,
• a ring electric motor with a rotor and a stator which is dynamically connected to the piston rod,
• a ball screw with a threaded spindle which is pivoted on the piston rod, and a threaded nut, the rotor being dynamically connected to the threaded spindle and the spring plate being dynamically connected to the threaded nut, so that rotary motion of the rotor which is initiated by the ring electric motor causes translational motion of the spring plate, and
• a bearing arrangement for fixing the strut on the vehicle body, the bearing arrangement having spherical bearing surfaces which allow at least a pivoting motion of the strut to the vehicle body,
• wherein in the region of the bearing arrangement the strut is dynamically connected to the vehicle body by way of a radially-stiff and rotationally-stiff component which is axially and cardanically soft.
