Assignee:

Eaton Corporation - Cleveland

International Classification:

F16H 48/06

US Classification:

475226

Abstract:

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.

International Classification:

F16H 48/06

US Classification:

475230, 475220, 475248, 475252

Abstract:

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.
