Abstract:
1. A device for the optional disengaging and engaging, respectively, of a friction clutch for motor vehicles, with an actuating mechanism, the clutch having an engaging state and a disengaging direction and the actuating mechanism being operatively connected with the friction clutch via at least one actuating force transmission member for applying an actuating force, the actuating force transmission member being pre-stressed in the disengaging direction by means of a spring, and there being a sensor device for sensing a variable representative of at least one of the group consisting of the disengaging and engaging state, respectively, of the friction clutch and of the state of wear on the friction clutch with a sensor; wherein by means of the sensor the force of the spring for pre-stressing the actuating force transmission member can be sensed as the variable representative of at least one of the group consisting of the disengaging and engaging state, respectively, of the friction clutch and of the state of wear on the friction clutch; and wherein the sensor is arranged in series with the spring for pre-stressing the actuating force transmission member.
