Abstract
A simplified differential assembly includes a single-piece open-ended hollow differential case and a free-floating differential gear mechanism mounted therewithin. The differential case is provided with a plurality of axial grooves formed on an inner peripheral surface of the differential case and extending between opposite open ends thereof. The differential gear mechanism includes a pinion shaft rotatably supporting a plurality of pinion gears in a free-floating manner, and adapted to drivingly engage the axial grooves of the differential case. The differential case is axially adjustably supported within an axle housing by means of two opposite mounting members. The mounting members are rotatably supporting the differential case at the opposite ends thereof through anti-friction roller bearings. The single-piece differential case may be used for differential assemblies in both open and limited slip configurations.
