Abstract
A differential is provided that includes a case, a cam side gear disposed proximate a first end of the case, and a side gear disposed proximate a second end of the case. The side gears have respective hubs. The differential further includes a first clutch pack disposed around the hub of the side gear. The differential further includes an annular engaging member disposed between the side gear and the case.
Claims18
A differential comprising:
- a case;
- a cam side gear disposed proximate a first end of the case, wherein the cam side gear has a cam side gear hub having an outer diameter that is smaller than an outer diameter of a remainder of the cam side gear, the cam side gear hub having a first axial end facing at least a portion of the case;
- a side gear disposed proximate a second end of the case, wherein the side gear has a side gear hub having an outer diameter that is smaller than an outer diameter of a remainder of the side gear, the side gear hub having a first axial end facing at least a portion of the case;
- a first clutch pack disposed around an outer radial surface of the side gear hub;
- and
- an annular engaging member disposed between the first axial end of the side gear hub and the case, wherein the annular engaging member comprises a cupped washer.

A differential comprising:
- a case;
- at least one pinion gear disposed in the case;
- a cam side gear disposed in the case and in meshed engagement with the at least one pinion gear, wherein the cam side gear has a cam side gear hub having an outer diameter that is smaller than an outer diameter of a remainder of the cam side gear, the cam side gear hub having a first axial end facing at least a portion of the case;
- a side gear disposed in the case and in meshed engagement with the at least one pinion gear, wherein the side gear has a side gear hub having an outer diameter that is smaller than an outer diameter of a remainder of the side gear, the side gear hub having a first axial end facing at least a portion of the case;
- a first lockup means operable to retard differential action of the differential;
- an actuating means for actuating the first lockup means;
- a reaction block disposed in the case between the cam side gear and the side gear;
- a second lockup means operable to retard differential action of the differential;
- and
- an annular engaging member disposed between the first axial end of the side gear hub and the case, wherein the annular engaging member comprises a cupped washer.
