摘要:
The invention relates to a friction clutch including in particular a pre-damper (A2) to which are axially juxtaposed a variable hysteresis friction system (62) and an independent slider friction system (74), systems (62, 74) between which is provided an intermediate friction washer (70) that is axially free and rotatingly connected to a guiding washer (34A), wherein said slider system (74) includes a slider washer (76) axially provided between said intermediate washer (70) and the guiding washer (34A) and elastically urged by the elastic washer of the system (62), the slider washer (76) including a means (78) capable of driving the washer (76) with a circumferential gap (j) lower than the circumferential gap (J) between the teeth (15e) of the axle (14) and the teeth of the web of a main damper in order to reduce the noise generated by the shocks between said teeth.

The friction clutch (10) includes two dampers (12, 14) coupled in series, known as a pre-damper (14) and main damper (12), each equipped with rotary input and output elements designed to be moved in relative rotation around a common geometric axis. The output element (20) of the main damper (12) is connected in rotation with the input element (28) of the pre-damper (14) in such a way as to form a rotary set (37). The set (38) includes at least one angle stop (45) elastically deformable, and designed to cooperate with a angle stop (28) that is complementary to an output unit (16) of the clutch (10) when the angular displacement between this output unit (16) and the set (37) reaches a predetermined value. The set (37) includes a rigid angle stop (27) angularly set back in comparison with the deformable angle stop (45), in such a way as to limit the angular deformation of this deformable stop (45).
