ABSTRACT:
A friction disc assembly includes a plurality of one piece or unitary friction elements each containing a pair of opposed planar friction surfaces. Each element is adapted for being supported within an opening of a clutch driven disc, wherein a pair of backing plates virtually supports each disc by trapping same within pairs of aligned openings. In a preferred form, the backing plates comprise an interference fit with the axially aligned boundaries of associated friction surfaces, and rivets which hold the backing plates rigidly to the driven disc are spaced from and hence out of contact with the friction elements. In a preferred form, each friction element includes a radially extending tongue which has a thickness equal to the thickness of the driven disc.
