Claims: I claim:

1. A friction disc comprising:

a plurality of arcuate segments arranged in end to end formation to define in part a substantially continuous annular friction member having opposite frictionally swept friction surfaces; and

an annular retaining ring including circumferentially spaced apart drive means positioned radially outwardly from said annular friction member;

each of said segments having circumferentially spaced apart projections extending radially outwardly from said annular friction member slidably connected to said annular retaining ring for limited circumferential movement relative thereto in the plane of said annular friction member;

said annular retaining ring including axially spaced apart first and second plate members positioned radially outwardly from said annular friction member;

said segment projections extending radially outwardly between the plate members and having circumferentially extending recesses for receiving said plate members such that said segments depend therefrom;

said first and second plate members being fixedly secured at opposite end portions to adjacent drive means.

2. The friction disc of claim 1 in which said axially spaced apart first and second plate members including spacing members circumferentially intermediate said projections, said spacing members cooperating with the plate members to retain the same within the projection recesses.

3. The friction disc of claim 1 in which said spaced apart drive means comprises a plurality of U-shalped drive members interposed between adjacent segments, said U-shaped drive members engaging said adjacent segments to position the same in spaced relation to each other.

4. The friction disc of claim 1 in which said segment projections extend radially outwardly of the plate members.
