METHOD FOR PRODUCING A PISTON-PISTON ROD ASSEMBLY, AND PISTON-PISTON ROD ASSEMBLY

摘要

Abstract Proposed is a method for producing a piston-piston rod assembly (16) for a fluid power device (11) such as a work cylinder or a shock absorber, wherein the piston (13) has a central opening for attaching the piston to the piston rod (15), and wherein the piston rod assembly (16) has at least one buffer sleeve (18) that can be used in the fluid power device (11) for damping purposes and that can be attached to the piston rod (15), the method comprising the following steps: - attaching the piston (13) to the piston rod (15) and connecting the piston (13) to the piston rod (15) in such a manner that the piston (13) is fixed on the piston rod (15) in an axially immovable manner, - attaching the buffer sleeve (18) to the piston rod (15) and connecting the buffer sleeve (18) to the piston rod (15) by means of laser welding in such a manner that the buffer sleeve (18) is fixed on the piston rod (15) in an axially immovable manner.
