Working cylinder without piston rod

摘要

A working cylinder which operates without a piston rod, comprising a cylinder tube, a piston which is displaceable therein and is provided with a pulling means, and a force transmission element which is connected with the pulling means and guided in axial displacement on the cylinder tube. In order to minimize the mounting work for the external attachment of the pulling means and at the same time increase the dependability of operation, the pulling means (1) is provided on the ends thereof connected to the force transmission element (2) with clamping pieces (3) which are provided with a toothed surface (5) on at least one outer side (4) and the force transmission element (2) is provided with a correspondingly toothed surface (6) against which the side (4) of the corresponding clamping piece (3) having the toothed surface (5) can be pressed via a pressing element (7). The corresponding toothed surface of the force transmission element (2) is longer than the clamping pieces (3) to allow for adjustment. The pressing element (7) and the force transmission element (2) together form an integral structure.
