Abstract

A clutch disk comprises a hub area designed for nonrotatable connection to a shaft and at least one friction lining element supported on a support area arranged radially outside the hub areas. A circumferential support surface for circumferential support of each friction lining element is provided on the support area at each circumferential end of each friction lining element.

Claims

1. A clutch disk comprising

a hub area designed for nonrotatable connection to a shaft,

a support area arranged radially outside of said hub area, said support area having at least one pair of circumferentially opposed support surfaces, and

a friction lining element disposed between each said pair of circumferential support surfaces, each said friction lining element comprising a carrier element and at least one axially facing friction lining formed separately from said carrier element and fixed to said carrier element, each said carrier element having a pair of circumferentially opposed ends which extend circumferentially beyond said friction linings and are supported by respective opposed support surfaces.

2. A clutch disk as in claim 1 wherein said support area has a plurality of apertures arranged in circumferential sequence, a plurality of said friction lining elements being arranged in respective said apertures, each said aperture being bounded by a pair of said support surfaces.

3. A clutch disk as in claim 1 wherein each said support surface extends substantially radially.

4. A clutch disk as in claim 3 wherein said support area comprises a disk element, said support surfaces being formed on said disk element.

5. A clutch disk as in claim 3 wherein each said end of said friction lining element has a recess which receives a respective said support surface therein.

6. A clutch disk as in claim 1 further comprising an elastic damping element between at least one of said circumferential ends and the respective said support surface.

7. A clutch disk as in claim 1 wherein each said support area comprises a radially extending recess, said circumferential ends being received in said recesses.

8. A clutch disk as in claim 7 further comprising an elastic material in at least one of said recesses.

9. A clutch disk as in claim 1 wherein said support area comprises radial support means for supporting each said friction lining element against radially outward movement.

10. A clutch disk as in claim 9 wherein each said pair of circumferentially opposed support surfaces converges toward each other from the radial inside to the radial outside, said radial support means comprising said converging support surfaces.

11. A clutch disk as in claim 9 wherein said support area comprises a radial support section extending radially outward beyond each said friction lining element, said radial support means comprising said radial support section.

12. A clutch disk as in claim 2 comprising a pair of cover disk elements having respective ring shaped areas which are rigidly connected against each other to form said support area, said cover disk elements being axially bent away from each other adjacent to said apertures to form recesses which extend essentially radially, said circumferentially opposed support surfaces being formed in said recesses, said circumferentially opposed ends being received in said recesses.

13. A clutch disk as in claim 12 wherein said cover disk elements are rigidly connected together by rivets between said apertures, said cover disk elements adjacent to said apertures extending axially above said rivets, said friction linings extending axially above said cover disk elements adjacent to said apertures.

16. A friction clutch as in claim 13 wherein said support area has a plurality of apertures arranged in circumferential sequence, a plurality of said friction lining elements being arranged in respective said apertures, each said aperture being bounded by a pair of said support surfaces.

17. A friction clutch as in claim 16 wherein said clutch disk comprises a pair of cover disk elements having respective ring shaped areas which are rigidly connected against each other to form said support area, said cover disk elements being axially bent away from each other adjacent to said apertures to form recesses which extend essentially radially, said circumferentially opposed support surfaces being formed in said recesses, said circumferentially opposed ends being received in said recesses.

18. A friction clutch as in claim 17 wherein said cover disk elements are rigidly connected together by rivets between said apertures, said cover disk elements adjacent to said apertures extending axially above said rivets, said friction linings extending axially above said cover disk elements adjacent to said apertures.

14. A clutch disk comprising

a hub area designed for nonrotatable connection to a shaft,

a support area arranged radially outside of said hub area, said support area having at least one pair of circumferentially opposed support surfaces which converge toward each other from radially inside to radially outside, and

a friction lining element disposed between each said pair of circumferential support surfaces, each said friction lining element having a pair of circumferentially opposed ends which are supported by respective opposed support surfaces, each pair of opposed support surfaces supporting said friction lining element against radially outward movement.

15. A friction clutch comprising a clutch disk, said clutch disk comprising

a hub area designed for nonrotatable connection to a shaft,

a support area arranged radially outside of said hub area, said support area having at least one pair of circumferentially opposed support surfaces, and

a friction lining element disposed between each said pair of circumferential support surfaces, each said friction lining element comprising a carrier element and at least one axially facing friction lining formed separately from said carrier element and fixed to said carrier element, each said carrier element having a pair of circumferentially opposed ends which extend circumferentially beyond said friction linings and are supported by respective opposed support surfaces.
