Spring-damper unit

The present invention relates to a spring-damper unit (10) for arranging between a first vehicle part and a second vehicle part, in particular between a vehicle body and a vehicle wheel of a motor vehicle. The spring-damper unit has a first fastening device (12) for fastening the spring-damper unit to the first vehicle part, and a second fastening device (12') for fastening the spring-damper unit to the second vehicle part. The spring-damper unit also comprises an elastic element (20) and a vibration damper (14) having two damper parts (16,18) which are movable relative to one another and which are arranged between the fastening devices in order to dampen relative movements between the vehicle parts and to regulate a spacing between the vehicle parts. A preload of the elastic element can be variably adjusted by means of a first adjustment device (26). Furthermore, one of the damper parts can be adjusted relative to one of the fastening devices by means of a second adjustment device.
