The invention relates to a friction clutch, comprising a counterpressure plate, a clutch cover connected to the counterpressure plate, a pressure plate, which can be displaced axially in relation to the counterpressure plate and is connected to the counterpressure plate in a rotationally fixed manner by means of leaf springs distributed over the circumference, a clutch disk having friction linings which are arranged axially between the counterpressure plate and the pressure plate in such a way that the friction linings can be stressed, a diaphragm spring, which is axially supported against a support associated with the clutch cover and which preloads the pressure plate against the counterpressure plate with a pressing force against the action of a lining spring force and of a leaf spring force in the closed state of the friction clutch in such a way that friction closure is established between the counterpressure plate and the pressure plate with respect to the friction linings, a disengaging device, which displaces radially inwardly pointing diaphragm-spring tongues of the diaphragm spring by means of a disengaging force in the direction of the counterpressure plate against a sensor spring force of a sensor spring preloaded between the diaphragm spring and the clutch housing, in order to open the friction clutch, and a force-controlled adjusting device that adapts the support to axial wear of the friction linings in the event of disengaging forces that exceed the sensor spring force. In order to design the adjusting device to be robust against shocks and vibrations, the support is associated with an adjusting ring, which is preloaded with a preloading force directed against the sensor spring and which is arranged in such a way that the adjusting ring can be axially displaced and rotated in relation to the clutch cover by means of an axial thread. |
