Central disengaging element for actuating clutch of motor vehicle, has displacement determination mechanism held by collar and opening in mantle surface of dirt collar that is arranged in inner ring of clutch release bearing

摘要

The element (1) has a sensor (3) provided in effective connection with magnets. A mechanism for displacement measurement and position determination of a piston is formed from the magnets and the sensor. The piston is guided into a cylindrical housing that is covered by a dirt collar (11) in an axially movable manner. The piston is effectively connected to an inner ring of a clutch release bearing (2). The mechanism is held by a collar (2d) and an opening in a mantle surface of the collar, where the collar is bent from the mechanism and arranged in the inner ring of the bearing.
