Hydraulic shock absorber for motor vehicles

摘要

A hydraulic dashpot for motor vehicles. It essentially comprises a fluid-filled shock-absorbing cylinder alone or accommodated in an outer cylinder and a piston that travels back and forth inside the shock-absorbing cylinder on the end of a piston rod. The piston rod extends through a centering component at one end of the shock-absorbing cylinder or of both cylinders and the edge of the shock-absorbing cylinder or of the outer cylinder is crimped around the centering component. The object is to improve support of the pressure-impact accommodator. The crimping (4) creates a neck (5) at that end of the shock-absorbing cylinder (1) that the impact-absorbing cap (6) rests against.
