Abstract: A mounting device for a pedal is installed on a fixed wall of a vehicle in an arrangement where a brace holding the pivotally mounted pedal is firmly attached to the wall and the connection between the brace and the pedal is self-releasing in the case of a collision.

Abstract: A friction clutch between an engine and a transmission in a motor vehicle has a diaphragm spring with prongs which are moved axially by a bearing in order to disengage the clutch. The bearing is mounted on an actuating device including a driven part carried by a support on the transmission case and a driving part which can be rotated by a clutch pedal. The actuating device can be moved axially by a first ramp assembly having complementary ramps on the support and the driven part. A second ramp assembly forms part of a wear compensating unit which automatically changes the axial position and/or the orientation of the diaphragm spring to compensate for wear at least upon the friction linings of the clutch disc forming part of the clutch. The second ramp assembly can include mating internal and external threads. A third ramp assembly is defined or carried by the driving and driven parts of the actuating device.

Abstract: An apparatus which is used to operate a clutch in the power train between the prime mover and the transmission of a motor vehicle has a bearing which can be moved axially against the prongs of the clutch spring to change the state of the clutch between an engaged and a disengaged condition. In addition to being movable in response to the depression of a clutch pedal, the bearing is also movable by a compensating unit forming part of the clutch operating apparatus and serving to compensate for wear upon the friction linings of the clutch disc and, if necessary, upon the pressure plate and the counterpressure plate of the clutch.
