US 8,475,321 B2 · Differential assembly

Abstract

A differential assembly having a gearset, which has first and second side gears and a plurality of pinion sets, and a case assembly. Each pinion set has a first pinion meshingly engaged to the first side gear, and a second pinion meshingly engaged to both the second side gear and the first pinion gear. The case assembly has a case structure, a case cover and a gearset mount. The case structure defines a cavity into which the gearset mount is received. The gearset mount defines a plurality of first pinion bores into which the first pinions are received, a plurality of second pinion bores into which the second pinions are received and a side gear pocket into which the first side gear is received. The gearset mount is fixedly and non-rotatably coupled to the case cover. The case cover is separately coupled to the case structure.
