FRICTION CLUTCH WITH PRE-DAMPER INCLUDING HYSTERESIS AND DEPENDENT SLIDER FRICTION SYSTEMS

摘要

The invention relates to a friction clutch including a pre-damper (A2) in which one face (34D) of the guiding washers (34A, 34B) two concentric inner (S1) and outer (S2) friction surfaces respectively associated with a slider friction system (70) and a hysteresis friction system (62), the slider friction system (70) including at least one slider washer (72) with means (74, 75) for rotating the same with a circumferential gap lower than the circumferential gap between the outer teeth (15e) of the axle (14) and the inner teeth (23) of the web (24), and including a load elastic washer (76) axially urging the slide washer (72) with an elastic force in order to define an independent slider system (70) capable of reducing the noise generated by the shocks between said teeth.
