Abstract: A fiction clutch device comprising a flywheel with a front end designed to be fixed to a vehicle crankshaft (11) and a rear end in the form of a hollow-shaped reaction plate (4) with a central recess (39) externally defined by a friction surface (37) and a friction disc (20), including at its external periphery at least a friction lining (16) to be in contact with the reaction plate (4) friction surface (37). The friction lining (16) is integral with a support (21) elastically coupled via a torque damper (20a) to a central hub (15) designed to be interlocked in rotation with a driven shaft. The torque damper (20a) penetrates into the reaction plate (4) central recess (39) and the flywheel (13) bearing between its front and rear ends the rotor (6) of a rotating electric machine (2) comprising a fixed stator (5).

Abstract: The invention concerns a friction clutch comprising a flywheel (3) with a front end designed to be fixed to a motor vehicle crankshaft (11) and a rear end in the form of a reaction plate (4) with a central recess (39) externally defined by a friction surface and a friction disc coupled with a central hub designed to be interlocked in rotation with the input shaft of a movement gear box comprising a clutch housing, the flywheel (13) bearing between its front and rear ends the rotor (6) of a rotating electric machine (2) comprising a fixed stator borne internally by a strut designed to be interlocked with at least one of the vehicle engine-clutch housing (14) block (62). The invention is applicable to a motor vehicle.

Abstract: The friction clutch has on the one hand a clutch engagement device comprising a diaphragm (3) and on the other hand a linkage (80), an actuator (50, 60, 70, 90, 91) for controlling the said linkage, and an adjustment device (10), for compensating for the wear on the friction linings (7) the actuator has an electric motor (50), a mechanical transmission (60) with an input element (51) and an elastic assistance device (70) bearing on a fixed part (91, 66) and on a movable part (61) forming a nut for cooperating with the output shaft (51) of the electric motor, the movable part (61) forms the output element of the mechanical transmission (60) while being able to act on the linkage (80) while the device for taking up wear (10) is mounted inside the declutching device.

Abstract: The invention concerns a clutch mechanism for friction clutch, in particular for motor vehicles, comprising a cover (8) with a transversely oriented base (80) and means (81) for fixing the clutch mechanism on a rotating flywheel (1), a pressure plate (3), elastic tabs linking in rotation, with axial mobility, the pressure plate (3) in rotation with the cover (8), axially operating elastic clutching means (7) axially stressing the pressure plate (8) in the opposite direction from the cover (8) base (80) and a disengaging device countering at will the action of said elastic clutching means (7): said elastic clutching means (7) are associated with two elastic washers (4, 6) mounted between the pressure plate (3) and the cover (8), and adapted to act on the pressure plate (3) parallel relative to the elastic clutching means (7) in a direction disengaging the clutch.

Abstract: A torque damping device including a support disc, a second guide washer provided with pressed sections and an intermediate hub disc. The support disc has elastic clamps acting on the hub disc for pushing the pressed sections towards the hub disc. The invention is particularly applicable to clutch friction for motor vehicles.

Abstract: A torsion damping device couples together an input element, such as a clutch friction wheel, and an output element comprising a hub. The damping device comprises a main damper and a predamper. The main damper comprises two guide rings arranged axially on either side of a damper plate. Each of the two dampers includes an axially acting friction device, and the damper plate meshes, with a circumferential clearance, with the periphery of a hub ring formed on the outer periphery of the hub. Both of the friction devices are incorporated in a single component, which comprises a first friction ring surrounding a second friction ring, and which includes radial arms which join the two friction rings together in such a way that the friction rings rotate together but are displaceable axially with respect to each other due to axial deformability of the radial arms.
