DRIVE UNIT OF A FLUID-ACTUATED LINEAR DRIVE AND METHOD FOR THE PRODUCTION THEREOF

摘要

A drive unit of a fluid-actuated linear drive includes piston rod, an annular drive piston seated coaxially on the piston rod and a buffer sleeve which is likewise seated coaxially on the piston rod. These components are secured to one another by one and the same common welded joint. Furthermore, a method for the manufacture of such a drive unit and a fluid-actuated linear drive equipped with such a drive unit is proposed.
