Clutch module having improved means for fastening it

A clutch module (10) for a motor vehicle, of the type comprising an assembly of adjacent components of generally annular form coaxial with each other, among which are arranged, in succession, a cover plate (12), a diaphragm (14), a pressure plate (16) coupled in rotation to the cover plate by fastening means (60) for enabling the pressure plate (16) to be displaced axially with respect to the cover plate (12), a friction disc (18) for coupling the clutch module in rotation to a driven shaft, and a reaction plate (20) fixed to the cover plate (12) by fastening means arranged at the outer periphery of the module, of the type in which the friction disc (18) includes at least one peripheral annular friction liner (36, 38), which is interposed between radial friction surfaces (40, 32), in facing relationship with each other, of the pressure plate (16) and reaction plate (20), wherein the diaphragm (14) bears against the cover plate (12, 52) and the pressure plate (16, 40) in order to bias the latter axially in the direction corresponding to gripping of the friction liner, and of the type in which the reaction plate (20) is so configured as to be mounted on a support plate (22) which is fixed in rotation to a driving shaft, by means of a set of fastening members (64) which are disposed radially inwardly with respect to the means fastening the reaction plate (20) on the cover plate (12), wherein each fastening member (64) comprises a head (66) which is received in a complementary housing (70) formed in the friction surface (32) of the reaction plate (20), with a threaded shank portion (74) of the fastening member projecting axially beyond the reaction plate (20, 28), in order to enable the module (10) to be secured by screw fastening on the support plate (22), and each of the cover plate (12), the diaphragm (14), the pressure plate (16) and the friction liners (36, 38) has at least one hole (121, 141, 161, 181) to enable access to be gained to the head (66) of a fastening member (64) with the aid of a tool when the said holes are aligned axially (Y--Y) with the head (66).
