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.

A spring carrier for mounting a spring strut to a vehicle body, the carrier comprising:
- a vibration damper comprising a cylinder and a piston rod which is axially guided in the cylinder;
- a first spring collar, a second spring collar, and a spring located between the spring collars;
- an actuator comprising 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 extending coaxially between the piston rod and the threaded spindle, the guide tube being configured to support the threaded spindle in a fixed axial position relative to said guide tube;
- a first resilient mount fixed to the guide tube for mounting the guide tube to the vehicle body;
- and
- a second resilient mount between the piston rod and the guide tube, whereby the piston rod can move relative to the first resilient mount.
