ABSTRACT:
A torsion damper assembly for an automotive clutch has a first part comprising a hub, a second part comprising two hub plates and a third part, the three parts being coaxial and rotatable independently of each other against springs acting over at least a predetermined portion of the angular displacement. The assembly has two sets of additional springs. These are mounted in recesses in the hub plates and in the hub, with their recesses facing each other in the region of a loose coupling defined between the hub and the hub plates. The additional springs associated with one hub plate are mounted in one of the recesses of that hub plate and of the hub, with a different circumferential clearance from the clearance with which the springs associated with the other hub plate are mounted in the corresponding recesses of that other hub plate and of the hub. The two hub plates are joined together for simultaneous rotation by structure which also act as phasing device for setting the loose coupling between the hub and each hub plate in its correct circumferential relationship.
