PCT No. PCT/FR93/01266 Sec. 371 Date Sep. 8, 1994 Sec. 102(e) Date Sep. 8, 1994 PCT Filed Dec. 17, 1993 PCT Pub. No. WO94/13970 PCT Pub. Date Jun. 23, 1994The clutch mechanism comprises a hollow cover plate (1) having at its outer periphery an annular skirt (3), at least one pressure plate (20), and a diaphragm (30), the outer periphery of which defines a Belleville ring (31), which, firstly, bears at its outer periphery on a deflection abutment (6, 60, 61, 62) carried by the cover plate (1) and, secondly, at its inner periphery it bears on a projecting element (22) of the pressure plate (20) so as to urge the plate (20) in a direction in which it is displaced away from the cover plate (1). The deflection abutment (6, 60, 61) is of resilient material and carries an integral centring extension (7, 71), oriented generally axially and interposed radially between the inner periphery of the skirt (3) of the cover plate (1) and the outer periphery of the diaphragm ( 30). |
