ABSTRACT:
A multiple wet disc brake or clutch is disclosed which includes a disc pack located in a housing. The stator discs in the disc pack are retained in the inner peripheral surface of the housing by curved tabs extending radially outward about the peripheral surface of each stator disc and engaging respective curved groove areas between margins in the inner peripheral surface of the housing. The stator disc tabs contact one margin of the respective grooves when the hub is rotated in a first direction to form a horn-shaped chamber between the converging outer surfaces of said respective tabs and grooves. An opposite second horn-shaped chamber is formed between the respective other margin of the grooves and stator tabs when the hub is rotated in a second direction. Brake or clutch cooling liquid and impurities contained therein will be forced under centrifugal force into the respective grooves and more specifically into the respective horn-shaped chambers which act as cooling liquid filters.
