  • Vibration damper assembly having a spring support with adjustable spring plate, and a spring support with adjustable spring plate
    Patent number: 5553713
    Abstract: A vibration damper assembly having a spring support. The spring support comprises a first support with a spring plate and a second support with a spring plate, whereby at least one spring plate is axially adjustable, so that the spring tension of a spring between the spring plates can be changed, the spring support also a comprising locking device which is active between the adjustable spring plate and the corresponding support, characterized by the fact that the locking device is loosened for the axial adjustment of the spring plate so that during the axial adjustment, the spring plate can be moved independently of the locking means from any desired position into another position without twisting, and the locking device is held in this position.
