Abstract
Slave cylinder for a pressure medium-actuated system for actuating the friction clutch of a motor vehicle, the slave cylinder including a cylinder housing, which is concentric to a transmission shaft and in which a ring-shaped piston is held, the piston being connected to a clutch-release bearing for actuation of the friction clutch. The cylinder housing is supported on a wall of the transmission to absorb the actuating forces acting on the clutch-release bearing by a mount which can absorb the wobbling movements of the cylinder housing. Wear on the guide and on the seals between the piston and the cylinder housing is reduced due to the ability of the clutch-release bearing to wobble jointly with the piston and the cylinder housing of the slave cylinder around a mount of spherical design and thus to its ability to follow the movements acting on it.
