Patent abstract
A brake system (100) utilizes a ring gear assembly (13). The ring gear assembly (13) includes a ring gear (13G) that rotates in the oil in the oil sump formed by the housing (101). The ring gear picks up oil as it rotates and as the oil is carried with to the top of the ring gear it falls by gravity into an accumulation cavity (3C). The oil then travels through an aperture (13A) and is then available for use by the reaction and friction plates (8 and 9) for cooling.
