Shock absorber with a damping force depending on the amplitude

摘要

A piston rod (5) carrying a piston arrangement (7) divides a cylinder (3) into a piston rod side workspace (9) and a distal workspace (11) that are in communication with each other. A switching ring (45) moves axially together with the piston rod. The operating path of the switching ring is limited by two stop surfaces (41,43). Impact by the switching ring against any of the stop surfaces is buffered by an absorbing medium pad.
