ABSTRACT:
The invention is directed to a spring strut for motor vehicles comprising a hydropneumatic vibration damper and a supporting spring. The vibration damper has a piston rod connected with a piston and is axially guided in a piston rod guide at the end of a container. The piston rod is outwardly sealed by a piston rod seal. The piston rod guide comprises a damping valve acted upon by external forces, such as the force of the supporting spring arranged between a structural component part connected with the vehicle and a spring carrier surrounding the container of the spring strut. The spring carrier acts on the damping valve with a contact surface. The supporting spring and/or the spring carrier cooperates with at least one auxiliary device exerting a force. The auxiliary device is supported at the container by a structural component part that is fixed with respect to the container or at a vehicle part which is connected with the container.
