Clutch disk assembly

Claim 2

Clutch disk assembly comprising a hub, a friction lining support disk coaxially surrounding said hub, said friction lining support disk and said hub having mutual relative torsional play force storage means operatively connected between said hub and said friction lining support disk and effective against relative torsion therebetween, load friction means ineffective over a first given range of torsional play between said hub and said friction lining support disk and effective over a second given range of said torsional play, said load friction means comprising a friction member and friction means effective over said second given range or torsional play, at least one force-storage device compressible over said second given range of said torsional play being effective with said friction means, and a pair of disk-like members disposed in axial spaced relationship on said hub and rigid therewith against relative rotation, said load friction means being disposed in the axial space between said pair of disk-like members, said pair of disk-like members rigid with said hub against relative rotation being formed with recesses defined by respective stop contours located opposite to and in registry with one another, said force storage means comprising respective force storage devices received in said recesses and engageable with said stop contours.

Claim 3

Clutch disk assembly according to claim 1 wherein said other of said pair of disk-like members is dish-shaped at radially inner regions thereof and is secured at radially outer regions thereof to said hub flange.

Claim 4

Clutch disk assembly according to claim 2 including spring means acting in direction toward said friction member engages said other member of said pair of disk-like members at the dish-shaped portion thereof.

Claim 5

Clutch disk assembly according to claim 2 including an intermediate disk fixed to said other member of said pair of dish-like members against rotation relative therewith and engaging said friction lining means, and springs means acting in direction toward said friction member, said spring means engaging said intermediate disk and the dish-shaped portion of said other member of said pair of disk-like members.

Claim 6

Clutch disk assembly comprising a hub, a friction lining support disk coaxially surrounding said hub, said friction lining support disk and said hub having mutual relative torsional play force storage means operatively connected between said hub and said friction lining support disk and effective against relative torsion therebetween, load friction means ineffective over a first given range of torsional play between said hub and said friction lining support disk and effective over a second given range of said torsional play, said load friction means comprising a friction member and friction means effective over said second given range of torsional play, at least one force-storage device compressible over said second given range of said torsional play being effective with said friction means, and a pair of disk-like members disposed in axial spaced relationship on said hub and rigid therewith against relative rotation, said load friction means being disposed in the axial space between said pair of disk-like members, an opposing disk located in axial spaced relationship with said friction lining support disk, spacer rivet means connecting said friction lining support disk to said opposing disk, one member of said pair of disk-like members disposed on said hub and rigid therewith against relative rotation being a flange extending from said hub, said load friction means disposed in the axial space between said hub flange and the other member of said pair of disk-like members comprising a friction member having an annular part defining a recess and surrounding said hub, and friction lining means disposed between said friction member and at least one member of said pair of disk-like members, and spring means urging said friction lining means toward said opposing disk, said other member of said pair of disk-like members and said hub flange are formed with mutually opposing registering stop contours engageable with said spacer rivet means.

Claim 7

Clutch disk assembly comprising a hub, a friction lining support disk coaxially surrounding said hub, said friction lining support disk and said hub having mutual relative torsional play force storage means operatively connected between said hub and said friction lining support disk and effective against relative torsion therebetween, load friction means ineffective over a first given range of torsional play between said hub and said friction lining support disk and effective over a second given range of said torsional play, said load friction means comprising a friction member and friction means effective over said second given range of torsional play, at least one force-storage device compressible over said second given range of said torsional play being effective with said friction means, and a pair of disk-like members disposed in axial spaced relationship on said hub and rigid therewith against relative rotation, said load friction means being disposed in the axial space between said pair of disk-like members, an opposing disk located in axial spaced relationship with said friction lining support disk, spacer rivet means connecting said friction lining support disk to said opposing disk, one member of said pair of disk-like members disposed on said hub and rigid therewith against relative rotation being a flange extending from said hub, said load friction means disposed in the axial space between said hub flange and the other member of said pair of disk-like members comprising a friction member having an annular part defining a recess and surrounding said hub, and friction lining means disposed between said friction member and at least one member of said pair of disk-like members, and spring means urging said friction lining means toward said opposing disk, said other member of said pair of disk-like members and said hub flange are formed with mutually opposing registering stop contours engageable with said spacer rivet means.
