A CLUTCH DISC AND A CLUTCH SYSTEM

摘要

The present invention describes a clutch disc, particularly used in a clutch system for effecting the selective coupling between an engine and a transmission of an automotive vehicle, comprising a first torsion disc (2), associatable to the engine, a second retention disc (3) rigidly associated to the torsion disc (2) and a flange (4) associated to the first and second discs (2, 3) by means of at least one damping resilient element (5) defining a first torsion- vibration damping system, the flange (4) being associated, by means of a second torsion-vibration damping system (7) to a hub (6) associatable to the vehicle transmission. The second torsion-vibration damping system (7) comprises at least one self-centering hub element (8) cooperating with the torsion disc (2), producing a friction torque between both of them and self-centering when the system (7) effects the damping of vibrations coming from the engine. The present invention also relates to a clutch system, particularly for effecting the coupling between an engine and a transmission of an automotive vehicle, comprising at least one "plateau", at least one bearing, at least one clutch actuation means and the presently disclosed clutch disc (1 ). This system can be made available in a single kit package for replacement in used vehicles.
