Embodiment Construction

[0030] figure 1 with figure 2 The friction disc 1 in the prior art is shown, which has two opposite coaxial annular friction plates 2, 2', and a progressive elastic member 3 is arranged between the two annular friction plates.

[0031] Each friction plate 2, 2'has a supporting member 4, 4', which is formed of a ring-shaped metal foil sheet, that is, a thin sheet of metal material, and its thickness is generally 0.2 mm to 1 mm. Each of the metal foils 4, 4'has an annular portion 5 and a claw 6 extending from the radially inner periphery of the annular portion 5. Each claw 6 has a first end 7 and a second end 8. The first end is connected to the radially inner periphery of the ring portion 5, and the second end has a through hole 9 through which a fixing rivet 10 passes, and the rivet is fixed to Side plate 11 of hub 12 ( figure 2 ). The hub 12, or friction disc 1 in general, is used for coupling to the input shaft of a gearbox, as is known.

[0032] The ends 7 and 8 are axially ...

Abstract

The invention relates to a friction disc (1) of a clutch comprising at least two opposed annular friction linings (2, 2') each one fixed to a backing (4, 4'), and elastic means (3) arranged between the backings (4, 4') so as to allow them to be brought closer together or further apart axially. Each backing (4, 4') comprises fixing a tongue (6) for attachment to a central hub (12), situated at the internal periphery of the backing (4, 4'). Each fixing tongue (6) is held axially between the hub (12) and a clamping washer (18) fixed to the hub (12) to prevent the tongue (6) from deforming during operation.

Description

Technical field [0001] The invention relates to a clutch friction disc, in particular to a clutch friction disc for a motor vehicle. Background technique [0002] Motor vehicle clutches are used to transmit torque between, for example, the crankshaft of an internal combustion engine and the input shaft of a gearbox. To this end, the clutch has a mechanism connected to the drive shaft and a friction disc connected to the input shaft of the gearbox. [0003] The clutch mechanism has a pressure plate and a reaction plate, and the pressure plate and the reaction plate rotate together and move one axially relative to the other so as to compress or release the friction plate in the engagement phase and the disengagement phase, respectively. [0004] The friction disc has two opposite friction plates, which are connected to an annular side plate or a friction disc hub. Each friction plate has an annular friction body, which is fixed on an annular support member. The support is generally ...
