    摘要: An unthreaded attachment of a joint eye to the piston rod of a vibration damper or spring strut, particularly by resistance welding. The piston rod and joint eye are held by one clamp electrode each, and the axial force created during welding is absorbed by a stop. A positive-locking connection is arranged between the piston rod and the clamp electrode to achieve axial fixing, so that joint eye can be attached in any installation state of the damper, even when the vibration damper is already installed.
