Abstract: A clutch module is of the kind comprising a mechanism (11), a clutch friction wheel (12) and a flywheel (13), the mechanism (11) itself comprising a cover plate (14) by which it is attached on the flywheel (13), a diaphragm (15) which bears on the cover plate (14), and a pressure plate (16) on which the diaphragm (15) bears. According to the invention, in the vicinity of its periphery having the larger diameter, the flywheel (13) carries ventilating fins (58,58') projecting axially from its front face, that is to say from its surface facing towards the pressure plate (16).

Abstract: The clutch mechanism comprises a cover plate (4), a diaphragm (5) bearing on the cover plate (4), assembly (8) applying the diaphragm (5) pivotally to the cover plate (4), and extending through the diaphragm (5) via widened apertures (53), together with at least one pressure plate (3) on which the diaphragm (5) bears by virtue of an annular projecting engagement element (31), which is divided into engagement sectors. The assembly (8) carries a support crown (71) which is coupled in rotation to the assembly (8), and which is extended in its plane and at its outer periphery by drive tongues (70) which extend through the projecting engagement element (31) of the pressure plate (3). The tongues (70) are adapted to be fixed at their free end to the pressure plate (3). In a modification, the drive tongues (70) are fixed with respect to a secondary abutment member (6, 60, 160) carried by the assembly (8).

Abstract: A clutch module including a clutch mechanism (11), a clutch friction disk (12) and a flywheel (13). The clutch mechanism (11) includes a cover (14) for securement to the flywheel (13). A Bayonet-type mounting (39) is interposed between the cover (14) and the flywheel (13). The bayonet mounting includes engagement lips (41) formed on the cover (14), and bosses (42) with grooves (44) formed on the flywheel (13). The lips (41) engage the grooves (44).

Abstract: A clutch module (10) is of the kind comprising a mechanism (11), a clutch friction wheel (12) and a flywheel (13), the mechanism (11) itself comprising a cover plate (14), which, for its attachment to the flywheel (13), comprises, at least locally, engagement member(s) (39) through which it is in engagement with a groove (40) provided for this purpose on the outer peripheral edge (42) of the flywheel (13).The engagement member(s) (39) are snap-fitting member(s), and a crown (50), for example the starter crown, prevents it from moving.Application in particular to clutch modules for motor vehicles.

Abstract: This relates to a clutch module of the kind comprising a mechanism (11), a clutch friction wheel (12), and a flywheel (13), the mechanism itself comprising a cover plate (14), a diaphragm (15) which engages on the cover plate (14), and a pressure plate (16A) on which the diaphragm (15) engages, while the flywheel (13) is constituted by a reaction plate (16) which is similar to the pressure plate (16A), together with a support plate (27) on which the cover plate (14) is fixed. According to the invention, the pressure plate (16A) is thicker at its outer periphery than at its inner periphery. Applicable to clutch modules, especially for motor vehicles.
