Piston rod connection for use in motor vehicle, has piston rod fastened to piston shaft housing using fastening unit that is designed as rotationally symmetric component and that stays in effective connection with housing and piston rod

摘要

The connection has a piston rod (7) fastened to a piston shaft housing (4) of a piston (3) using a fastening unit (5) that comprises a flange. The fastening unit is designed as a rotationally symmetric component and stays in effective connection with the housing and the piston rod. A damping unit is arranged between a shoulder of the piston rod and a stop of the fastening unit, where the shoulder radially points outward. The damping unit is designed as an O-ring (6) and stays under axial and/or radial pre-stressing.
