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

Damped flywheel, especially for a motor vehicle

A double damped flywheel for a motor vehicle comprises a first mass having a central hub, a second mass, a torsion damper, and a friction device working axially between the first mass and the second mass and having at least one friction ring in contact with a friction surface. The friction ring and the associated friction surface are carried by a support cage which is fitted on a local portion, having an increased radius, of the central hub, this cage being located axially by a transverse thrust plate of the first mass, so that the cage is located between this thrust plate and the anti-friction bearing by which the second mass is mounted on the first mass.

A torsion damping device includes a support wheel, having first fastening screws for attaching it to a driving shaft, a damper plate, and peripheral springs acting between the support plate and the damper plate. The damper plate, carrying a pair of guide rings, constitutes, together with the springs and a drive plate, a torsion damper which is contained in a sealed housing, the components of which are secured together by second fastening screws. The inner periphery of the sealed housing has a diameter greater than that of the pitch circle on which the holes for the first fastening screws are arranged in the support wheel, while the damper plate emerges radially from the housing, in a manner which provides axial location but circumferential sliding movement of the damper plate in the housing while preserving sealing. The second fastening screws of the housing are separate from the first fastening screws and their holes in the support wheel, while one of the components defining the housing carries a cover for urging the torsion damper into rotation, the latter being conformed so as to cooperate therewith.

Torsion damping device with peripheral resilient means arranged in a

A fluid coupling apparatus comprises a torque convertor and a locking clutch having a torsion damper. The coupling plate which couples the torsion damper to a coupling element of the clutch, arranged to act as a piston, is provided with two sets of circumferential tongues, with the tongues of at least one of these sets each having a slight, wave-shaped, axial deformation.

Fluid coupling apparatus

In a torque transmission, particularly for an automotive vehicle, of the kind including a hydraulic coupling unit and a locking clutch, the latter comprises essentially a piston and a clutch plate, the piston being mounted slidably on a hub to enable the friction pad to be gripped. The piston is coupled with the clutch plate through profiled coupling.
