A friction clutch, more particularly for motor vehicles, has a pressure plate 3 which is connected rotationally secured but axially displaceable to a limited extent to a housing 2, and between the housing and pressure plate there is at least one operating means 4b and an energy accumulator formed by a diaphragm spring 4 by which the pressure plate can be biased in the direction of a clutch disc 8. The disc can be clamped between the pressure plate and a counter pressure plate 6, such as a flywheel, and an adjustment device is provided which compensates at least for the wear on the friction linings 7 of the clutch disc 8. The adjustment device comprises a wear compensating unit 16 which is provided between the operating means 4b or energy accumulator 4 and pressure plate 3 and which carries out an axial adjustment between the operating means or energy accumulator and pressure plate corresponding to the wear of the linings. On reaching the adjustment corresponding to the actual state of wear of the friction linings 7, the wear compensation unit is restricted in its adjustment function by means 17 provided on the pressure plate 3. The unit 16 includes spring-loaded wedges (FIG 3) and the means 17 includes a pair of leaf springs 22 in a slit 21. <IMAGE> |
