Flywheel, for motor vehicles

Reaction plate for friction clutch, in particular for motor vehicles

Damped flywheel adapted to be interposed in a motor vehicle propulsion

A torsion damper comprising two coaxial parts which are mounted for rotation of one with respect to the other, with, interposed between these coaxial parts, apart from a centring element, circumferentially acting springs which are lodged in a cavity closed by the centring element, and friction device arranged outside the cavity. The friction device comprise, firstly, a cassette carried by one of the two coaxial parts, and secondly, a drive ring carried by the other coaxial part. The cassette includes at least two friction discs arranged to be coupled in rotation variously to the two coaxial parts of the damper, together with an axially acting resilient ring for holding the friction discs axially together.

A clutch release bearing assembly comprises a clutch release bearing having an actuating element which defines an actuating nose, a coupling member carried by a connecting piece which is prefitted to the diaphragm or other declutching member of the clutch, and at least one resilient retaining ring for holding the coupling member permanently between a drive surface of the connecting piece and an actuating flank or thrust shoulder of a groove formed around the actuating nose. This groove is elongated away from the thrust shoulder, so that at least one axially acting resilient ring can be fitted into the groove in advance, with the thrust shoulder acting as an abutment for this ring.

Clutch release bearing assembly, especially for a motor vehicle

A motor vehicle includes a primary unit and a secondary unit, i.e. the engine and gearbox respectively. The clutch release bearing includes a sliding manoeuvring element carried by the secondary unit and carrying a ball bearing, the outer ring of which carries a housing which is so conformed as to define the actuating element of the clutch release bearing that engages with the clutch diaphragm, typically through a standard main coupling member carried by the diaphragm. The actuating element is formed with an engagement recess in which is fitted an intermediate coupling member coupling the actuating element to the main coupling member, while the manoeuvring element of the clutch release bearing is of generally tubular shape.

An actuating assembly, for coupling a clutch release bearing in traction to the diaphragm of a clutch of an automotive vehicle, includes an actuating member carrying a coupling piece and including a flange having two distinct openings separated by a bridge portion. The coupling piece has two arms which are arranged to hook one over the other, and which extend through the openings in the flange. Each arm of the couplings has at least one local deformation which increases its length in a resilient manner.

In a clutch comprising at least one pressure plate with axially bored radial lugs at its periphery, a travel limiter is disposed in at least one of the axial bores. It comprises a rigid peg movable axially between two bearing surfaces in axial face-to-face relationship of the cover-reaction plate assembly. The peg is mounted with friction in a friction bush which is pressed against the peg by clamping members. The bush comprises axial retaining members for retaining it in position through the axial bore. The clamping members are adjusted so that the peg can slide in the bush when acted on by engagement means of the clutch, but not when acted on by disengagement means specific to the plate.
