Abstract:
Friction clutch mechanism of the type having a rear cover (52), a front pressure plate (51) connected with respect to rotation to the cover (52) while being able to move axially with respect to it, abutment means (14) carried by the pressure plate (51), axially acting engaging means (53) acting between the cover (52) and the abutment means (14), and a wear take-up device comprising on the one hand means (54) with ramps (56) fixed with respect to rotation carrying an external set of teeth (59) and placed between the pressure plate (51) and the abutment means (14) in order to constitute a pressure plate (51, 54) with a variable thickness between its friction face (11) and the abutment means (14) and comprising on the other hand a unit (10) carried by the cover (52) and which has a piece (62), fixed to the cover (52), forming a support roughly in a U-shape with a top central web (64), in the general shape of a horizontal plate, oriented roughly tangentially, and two opposite lateral wings (65, 66), each of which extends vertically downwards in an axially oriented plane perpendicular to the top web and each of which has a hole (61) for rotably mounting an assembly (67, 63, 60), the piece (62) forming a support having a front fixing lug (68) which extends vertically upwards in a transverse plane perpendicular to the overall axis (X--X) of the mechanism from a front transverse edge (211) of the plate forming a central web (64) and which is fixed by riveting (155) to a peripheral edge (152, 154) of the cover (52), characterised in that the support (62) has at least one axially oriented stabilisation lug (171) which extends towards the rear through an opening (156) formed in the cover (52, 218) and delimited by at least one horizontal abutment edge (158, 222) with a roughly tangential orientation, which constitutes an abutment surface for the stabilisation lug (171).
