LIMITED SLIP DIFFERENTIAL USING FACE GEARS AND A PINION HOUSING

摘要

A differential (10) includes a differential case (50); a side gear (32) comprising a helical face gear; a helical pinion (24) configured for meshing engagement with the side gear (32); and a pinion housing (12) configured to support the helical pinion (24). The pinion housing (12) includes a first face (16); a second face (18) opposing the first face (16); a first projection (20) located on the first face (16); and a second projection (22) located on the second face (18). In some embodiments, the differential (10) further comprises an actuator (36) configured for engagement with the pinion housing (12) and a plurality of friction plates (48) disposed between the actuator (36) and the differential case (50). The pinion housing (12) also includes an aperture or hole (26) extending radially inwardly from an outer radial surface (38) of the generally annular ring; and a channel (30) extending from the first face (16) to the second face (18), wherein the channel (30) is substantially radially aligned with the aperture or hole (26).
