An impact buffer working with a protective beam,in particular for vehicle impact dampers

摘要

The stop (2) for limiting the travel of a shock absorber protective bellows (3) comprises an elastic compression element (7) passed through by the shock absorber rod (6). The rod is connected at one end to a frame relative to which the stop is held by a support (14). The other end of the rod slides in the shock absorber cylinder (5) which is connected to a part capable of displacing relative to the frame. One end of the bellows is connected to the stop and the other end is driven by the cylinder during absorber movement. The stop limits travel of the cylinder in the direction of the frame and exerts a reaction force on the cylinder at the end of travel. The compression force of the stop, at the end of travel, is transmitted to the cylinder by the stop through the bellows.
