Abstract

A spring carrier for mounting a spring strut to a vehicle body includes a vibration damper having a cylinder and a piston rod which is axially guided in the cylinder, first and second spring collars, and a spring located between the spring collars. An actuator includes a nut and a threaded spindle surrounding the piston rod, the actuator being driven to change the relative axial position of the spring collars. A guide tube extends coaxially between the piston rod and the threaded spindle, the guide tube being fixed to the vehicle body by a first resilient mount, the piston rod being fixed to the guide tube by a second resilient mount, whereby the piston rod can move relative to the first resilient mount.
