Pneumatic spring for vehicle has control element with support face formed as spring plate for second spring which with maximum retracted position of control element is supported on end face of roll tube

摘要

The pneumatic spring includes a U-bellows between an outer tube and roll tube, and a floating mounted control element pretensioned by a spring against one of the relatively movable sub-assemblies of the pneumatic spring. The control element (37) has a support face which with maximum retracted position of the control element is supported on an end face of the roll tube (23). The support face is formed by a spring plate (77) for a second spring (73) which acts in the opposite direction to the first spring (43) and co-defines the position of the control element.
