Abstract

The invention relates to a slave cylinder (1) for a clutch actuating device with a piston (2) and a release bearing (3) with an outer ring (4), wherein the release bearing (3) is secured by means of a transport lock (6) fixed on this piston (2), and the invention relates to a method for fixing said piston (2) on a release bearing (3).

Description

Technical field [0001] The invention relates to a slave cylinder for a clutch operating device, which has a piston and a release bearing, wherein the release bearing is fixed on the piston by means of a transport safety device. Background technique [0002] WO 2014 / 026686 A1 describes a slave cylinder of this type with a transportation safety device. The bearing of the slave cylinder is fixed on the piston by means of a retaining ring with a hook and configured as an elastic element. In this case, however, undesirable debris is generated during the assembly of the piston, which debris may, for example, cause filling of the bearing in subsequent operations. The retaining ring including the hook requires a large axial installation space. [0003] Other slave cylinders are known from WO 2008 / 086763 A1 and WO 2014 / 032665 A1. Summary of the invention [0004] Therefore, the following technical task exists to provide a slave cylinder in which the transportation safety device can be int...
