Abstract

A friction component for a clutch or brake including a facing of friction material and at least one metal section of plate-like form embedded in a rear surface of that facing and having an integral rivet or other fastener projecting outwardly from the facing rear surface. The metal section extends across a relatively small part of the facing rear surface and if there is a plurality of such sections they may be interconnected through integral bands. In the case of an annular friction component the metal sections are spaced circumferentially around the friction facing and if connecting bands are used they are preferably adjacent the inner periphery of the facing.

Claims

1. A friction component including, a facing of friction material, at least one metal section of plate-like form secured to said facing so as to be held against movement relative thereto, said metal section being embedded within a rear surface of said friction facing so as to be exposed at that rear surface and so that the periphery of the metal section is completely surrounded by said friction facing, and at least one hollow fastener formed integral with said metal section and projecting therefrom outwardly away from said rear surface, said fastener providing means whereby said friction component can be attached to a clutch plate cushioning spring.

2. A friction component according to claim 1, wherein said section extends across a small part of the area of said rear surface.

3. A friction component according to claim 1, wherein said facing is an annular section of friction material.

4. A friction component according to claim 1, wherein a plurality of said plate-like sections are provided on said facing in spaced relationship.

5. A friction component according to claim 4, wherein adjacent said plate-like sections are interconnected to form a single member.

6. A friction component according to claim 5, wherein said interconnection comprises an integral relatively narrow metal band.

7. A friction component according to claim 6, wherein said facing is an annular section of friction material, said plate-like sections are arranged in circumferentially spaced relationship around said annular section, and each said band extends in a substantially straight path between the said adjacent plate-like sections and is located adjacent the inner periphery of said annular section.

8. A friction component according to claim 6, wherein said interconnected plate-like sections are arranged in a circle in circumferentially spaced relationship and project laterally outward from one side of said bands, whereby said plate-like sections and said bands cooperate to form a substantially annular skeleton in which said bands form part of the inner periphery.

9. A friction component according to claim 1, wherein said plate-like section is secured to said facing by adhesive.

10. A friction component according to claim 1, wherein said fastener is a rivet-type fastener.

11. A friction component according to claim 1, wherein the face of said plate-like section which is exposed at the rear surface of said facing is substantially co-planar with said rear surface.

12. A friction component according to claim 1, wherein said facing is moulded about said plate-like section.

13. A friction component according to claim 1, wherein said metal section is a phosphated metal section.

14. A friction component according to claim 1, wherein said fastener is closed at its outer end.

15. A clutch plate assembly including a friction component according to claim 3.
