Abstract
A device is disclosed for the optional engaging and disengaging of a friction clutch for motor vehicles with a preferably hydraulic actuating mechanism, such as a central disengaging device, which, in order to apply an actuating force, is operatively connected with the friction clutch via at least one actuating force transmission member, such as a release bearing, which is pre-stressed in the disengaging direction by means of a spring. The device also has a sensor device with a sensor for sensing a variable representative of the engaging respectively disengaging state of and/or the state of wear on the friction clutch. According to the invention, the force of the spring for pre-stressing the actuating force transmission member or of a spring arranged in parallel with it can be sensed using the sensor, as a variable representative of the disengaging and engaging state of and/or the state of wear on the friction clutch. As a result, a device is created in which a variable representative of the disengaging respectively engaging state of and/or the state of wear on the friction clutch can be sensed in a particularly simple manner.
