Abstract:
Friction clutch mechanism of the 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 to 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), and two opposite parallel lateral wings (65, 66), each of which extends vertically downwards and each of which has a hole (61, 61â€²) for rotatably mounting one end of a shaft (67) of an assembly (67, 63, 60) including a worm (63), cooperating with the set of teeth (59) of the ramp means, which is carried by the shaft (67), characterised in that at least one of the lateral wings (65, 65â€²) of the support (62) carries a bearing (3, 3â€²) with a central hole (361, 361â€²) which receives one end (69, 69â€²) of the shaft (67) and which is housed in a blind hole (61, 61â€²) in the wing in which it is slipped and then trapped.
