ABSTRACT:
A friction disc assembly (10) for use in clutch packs is disclosed. The friction disc assembly (10) includes a pair of annular friction facings (12-30) and an annular core plate (11) positioned between the friction facings (12-30). Each of the friction facings (12-30) includes a plurality of adjoining facing segments (14-31). Each segment (14-31) includes a notch (15-33) at one end and a tab (16-32) at the other end. Each notch (15-33) receives an adjoining tab (16-32) and defines a reservoir (21-35) adjacent the tab (16-32). The reservoir (21-35) receives unwanted stray fibers and cooling fluid. Another embodiment for wide core plates includes a pair of tabs (43-44) received in a pair of notches (45-46). Reservoirs (47-48) are defined adjacent the ends of the tabs (43-44).
