摘要:
A torsion damper comprising a first rotating element (12) and a second rotating element (14), coaxial with each other and defining between them an annular housing which receives a resilient damping device (32), wherein the greater part of the annular housing (30) is delimited by at least two components (20, 22, 24) of a first one (12) of the two rotating elements. The second (14) rotating element includes a plate (26) together with an annular disc (36) which is fixed to the plate by a set of rivets (39) arranged circumferentially in the vicinity of the inner peripheral edge of the disc (36), and having an annular friction damper system (174) arranged between the first rotating element (12) and the disc (36) of the second rotating element (24). The annular friction damping system (174) is disposed radially outwardly of the zone occupied by the rivets (39) by which the disc (36) is fixed, and radially inwardly with respect to the sealed annular housing (30).

The torsion damper comprises a first rotating element (12) delimiting the greater part of a sealed annular housing (30) which receives a resilient damper (32) and a lubricating agent for this damper. A second rotating element (14) Comprises a disc (36) which penetrates into the sealed housing (30). Sealing rings close the housing (30) sealingly. Each sealing ring is mounted in axial compression between two support surfaces, one of which consists of an annular ridge carried by the disc (36), while the other consists of a shoulder formed on the other rotating element.

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.
摘要:
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.
摘要:
A damping device (10) of the type comprising damping member which are disposed between two coaxial rotating masses (12, 14), and of the type in which the damping member comprise a resilient damping mechanism (32) which is interposed between the two rotating masses (12, 14), a first friction damping mechanism (44) that includes a first annular friction surface (54) which is displaceable axially under the action of first resilient member, which urge it axially towards the first annular friction surface (54), and a second friction damping mechanism (46) which includes at least one further annular friction surface (66) displaceable axially under the action of second resilient member. The first and second resilient members are made in one piece (76), consisting of a ring (78) and a set of resiliently deformable radial fingers (80).
摘要:
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.

The invention concerns a dual mass damping flywheel comprising a secondary flywheel (13) including a torque limiter (19) interposed between a hub (18) external periphery and the internal periphery a reaction plate (16) Whereon is directly mounted an internal ring (160) made of different material. The invention is applicable to motor vehicles.
摘要:
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.
摘要:
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.
