摘要： A friction clutch mechanism includes a diaphragm spring, a pressure plate having a peripheral fulcrum acting against a first face of the diaphragm spring, and a pair of axially opposed intermediate fulcrums supported by a clutch cover and acting on the opposite faces of the diaphragm spring along a radially intermediate portion thereof. The friction clutch mechanism has an additional elastic element, operatively associated with a first intermediate fulcrum of the pair of axially opposed intermediate fulcrums, and axially and elastically compressible in response to a deflection of the diaphragm spring towards an open friction condition. The additional elastic element has a radially innermost annular portion resting on one or more bearing surfaces supported by the clutch cover, and a radially outermost annular portion that cantilevers and has a protrusion circumferentially extended and axially projecting towards the first face of the diaphragm spring to serve as the first intermediate fulcrum.

摘要： A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier. The input part includes a rotor carrier, an inner-plate carrier separate from the rotor carrier, and an inner plate rotationally fastened to the inner-plate carrier. The spring device is for bracing the outer plate and the inner plate together with a pressing force to close the friction clutch. The connecting means includes an actuating surface via which the friction clutch can be actuated by an actuating device.

摘要： A friction clutch includes a housing, an axially displaceable pressure plate, a lever system for displacing the pressure plate, a ramp system arranged between the pressure plate and the lever system, a torsion device for rotating the ramp system, and a control device. The torsion device has a spindle to drive the ramp system and a drive gear with an external profile. The control device has a fastening portion fixed to the housing and a pawl with a plurality of tongues to forming a positive interlock. At least one tongue is arranged to engage the external profile. Each tongue is separated from another tongue by a gap extending in the axial direction. At least one gap, starting from a tip of the tongue, extends in the axial direction 30% or less of a minimum distance between the tip and the fastening portion.
