A differential includes a differential case; a side gear; a pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the pinion. The pinion housing includes a first face; a second face opposing the first face; a first projection located on the first face; and a second projection located on the second face. The pinion housing also includes an aperture or hole extending radially inwardly from an outer radial surface of the generally annular ring; and a channel extending from the first face to the second face, wherein the channel is substantially radially aligned with the aperture or hole. In embodiments, the pinion housing includes one or more transfer formations configured to transfer torque from the differential case, and the pinion housing is configured to permit movement in an axial direction between a pair of side gears.

Limited slip differential using face gears and a pinion housing

Face gear

A differential includes a side gear comprising a helical face gear; a helical pinion configured for meshing engagement with the side gear; a pinion housing configured to house the helical pinion; and a first support member configured to support the helical pinion. The side gear rotates around a differential axis. The helical pinion has a first end and a second end opposing the first end. The pinion housing comprises a generally annular ring and includes an outer radial surface; an inner radial surface; and an aperture extending radially inwardly from the outer radial surface. The first support member is disposed radially inwardly relative to the inner radial surface of the pinion housing. In some embodiments, the differential further includes a second support member configured to support the helical pinion. The second support member is disposed radially outwardly relative to the outer radial surface of the pinion housing.

Gear set for differential

A differential includes a differential case; a side gear comprising a helical face gear; a helical pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the helical pinion. The pinion housing includes a first face; a second face opposing the first face; a first projection located on the first face; and a second projection located on the second face. In some embodiments, the differential further comprises an actuator configured for engagement with the pinion housing and a plurality of friction plates disposed between the actuator and the differential case. The pinion housing also includes an aperture or hole extending radially inwardly from an outer radial surface of the generally annular ring; and a channel extending from the first face to the second face, wherein the channel is substantially radially aligned with the aperture or hole.

A gear train is provided that includes at least one side gear comprising a helical face gear and a plurality of helical pinions in meshing engagement with the helical face gear. The gear train may further include an absorber configured to provide an axial force on at least one of the plurality of helical pinions. A differential may also be provided including a differential case and a gear train disposed in the differential case. The gear train includes at least one side gear comprising a helical face gear and a plurality of helical pinions in meshing engagement with the helical face gear. The gear train in the differential may further include a means for providing an axial force on at least one of the plurality of helical pinions.
