Abstract:
An axle assembly that includes a housing, an input pinion, a ring gear, an angular contact bearing, and a differential assembly. The input pinion has a plurality of pinion teeth and is received in the housing for rotation about a first axis. The ring gear, which is received in the housing, is a bevel gear having ring gear teeth that define a pitch angle and are meshingly engaged with the pinion teeth. The angular contact bearing supports the ring gear for rotation on the housing about a second axis that is transverse to the first axis. The angular contact bearing has a first race, which is integrally formed into the ring gear, a second race, and a plurality of bearing balls disposed between the first and second races. The differential assembly has a differential case that is mounted to the ring gear for rotation therewith.
