A friction clutch comprising a pressure plate ( ) consisting of tow half-plates ( A, B) integral in rotation with the input shaft but axially mobile, relative to each other, under the action of the device compensating play due to wear. The wear compensating device comprises a pair of complementary ramps ( ) circumferentially arranged, axially associated respectively with each of the half-plates ( A, B), one support ramp ( ) being integral in rotation to one ( B) of the half-plates, the other adjustment ramp ( ) being adapted to move circumferentially relative to the support ramp ( ) in the compensating direction increasing the global thickness of the first plate ( ) and prevented form moving in the other direction by one-way means ( ). The circumferential movement is controlled by a tripping element ( ) sensitive to wear condition, the adjusting ramp ( ) being arranged at the periphery of an inertial piece ( A).

A torsion damper, especially for a motor vehicle clutch, comprises two coaxial parts, namely a primary and a secondary coaxial part respectively, which are mounted for rotation of one with respect to the other, with circumferentially acting springs, mounted in a grease cavity, acting between the two coaxial parts, while a centring bearing which closes the grease cavity, and a friction assembly, also act between the two coaxial parts. The friction assembly is arranged outside the cavity, with the centring bearing being between the cavity and the friction assembly.

Torsion damper, with lubricated springs especially for a motor vehicle

A torsion damper, in particular for a motor vehicle clutch, comprises two coaxial parts, namely a primary coaxial part and a secondary coaxial part which are mounted for relative rotation against the action of springs, with friction member also being arranged to act between the two coaxial parts. The friction member comprise a radially acting friction ring in the form of a sleeve, meshing, with a clearance, with one of the coaxial parts, together with a radially acting spacing ring, which is coaxial with the friction ring and which engages either the outer or the inner periphery of the latter, the spacing ring being mounted on the other one of the coaxial parts for rotation with that part.

An assembly of two components comprises a male member and a female member, the latter having a shoulder, with the male member abutted against the shoulder in back-to-back relationship. The female member has a groove. The male member is worked so as to cause its material to invade at least part of this groove in plastic flow. The groove is located beside the periphery of the shoulder having the larger diameter (i.e. the outer periphery of the shoulder), so that the plastic flow of the material of the male member takes place radially outwardly. Arrangements are also provided for sealing the assembly of the two components. The invention is applicable, for example, to torsion dampers for motor vehicles.

Method of assembling a transverse plate with a crown ring of a torsion

A torsion damping device comprises two coaxial masses and a friction device, which acts between the two coaxial masses and surrounds a central hub of the first mass. The friction device is a unitary assembly which comprises at least one element of elastic material, with a friction ring secured over at least one of its faces, for contact with a first friction surface carried by one of the coaxial masses. This unitary assembly is interposed, so as to be gripped radially, between the first friction surface and a second surface fixed to the other mass. The invention is applicable to torsion dampers for motor vehicles.

Torsion damping device, especially for a motor vehicle

A torsion damping device of the kind comprising two rotatable parts with coil springs interposed between them. At least one friction pad is associated with each spring so as to come into engagement with a contact zone of one of the said coaxial parts. In accordance with the invention, there is associated with each of the friction pads an intermediate resilient member which is radially deformable and which has a first engagement zone for engagement with a turn of the spring, together with a second engagement zone for contact with the friction pad, the intermediate resilient member being interposed radially between the friction pad and the spring.

A speed changer pulley comprises two annular flanges one of which is movable axially on a hub under the control of elastic return member constituted by at least one diaphragm encased with a covering of resilient material. The peripheral part of the diaphragm is prolonged radially outwardly by a rim of resilient material fitted into a housing in the movable flange.

A pulley of a speed changer comprises two annular flanges one of which is movable axially on a hub under the control of elastic return means constituted by at least one diaphragm encased with a covering of resilient material. A bridging element made of resilient material is interposed between the diaphragm and a bearing piece fixed to the hub. Towards its extremity adjacent to the bearing piece, the bridging element is fitted into a housing made in the bearing piece.
