Abstract

Clutch disk assembly includes a hub, a friction lining support disk coaxially surrounding the hub, the friction lining support disk and the hub having mutual relative torsional play force storage means operatively connected between the hub and the friction lining support disk and effective against relative torsion therebetween load friction means ineffective over a first given range of torsional play between the hub and the friction lining support disk and effective over a second given range of the torsional play, the load friction means comprising a friction member and friction means effective over the second given range of torsional play, at least one force-storage device compressible over the second given range of the torsional play being effective through the friction member, and a pair of disk-like members disposed in axial spaced relationship on the hub and fixed thereto against relative rotation therewith, the load friction means being disposed in the axial space between the pair of disk-like members.

Dependent claims

A clutch plate, particularly for use in the clutches of automotive vehicles, comprising a first component including a hub and a pair of axially spaced disk-shaped members non-rotatably secured to said hub;

a second component rotatable with reference to said first component and including a clutch disk disposed between said disk-shaped members;
and means for yieldably opposing rotation of said second component from a neutral position with reference to said first component, including a load friction device interposed between said disk-shaped members and arranged to oppose a second stage of rotation of said second component following a first stage of rotation from said neutral position, said load friction device comprising at least one load friction member and friction means effective during said second stage, said rotation opposing means further comprising a least one energy storing element interposed between said load friction member and said clutch disk on the one hand and at least one of said disk-shaped members on the other hand to be engaged by said clutch disk during said second stage of rotation of said second component, said clutch disk, said load friction member and said one disk-shaped member having window means for said energy storing element.
