Hydraulic car shock absorber - has flow coupling with control discs, forming with support spring traction stop

摘要

The shock absorber has a cylinder (1), contg. the damping fluid and an axially displaceable piston rod (2) which, in turn, carries a piston (3) which divides the cylinder into two work chambers (4,5). A flow connection from one work chamber to the compensating chamber (9) is controlled by an axially displaceable spring-mounted control disc (10) in the cylinder. The disc forms a mechanical traction stop together with the spring (12) and a hydraulic traction stop together with a support ring (11). ADVANTAGE - Independent operation of the traction stop of shock absorbing action.
