ABSTRACT:
A locking differential includes an annular center cam member freely rotatably supported within an annular central driver member without the use of any keying device, such as a snap ring, thereby to simply the construction and assembly of the differential, and to reduce cost. The center cam member is longitudinally maintained in place by the biasing forces applied to the clutch members arranged on opposite sides of the central driver member by helical compression springs arranged externally concentrically about the side gears, respectively, and by the holdout rings that are connected with the clutch members. The center cam member and the central driver member have adjacent outer and inner circumferential surfaces, respectively, that are smooth, continuous, and uninterrupted. The holdout rings are rotatably connected at their remote ends with the clutch members by integral annular outer ribs that extend within corresponding grooves contained in the counterbore wall surfaces.
