Abstract
An axle assembly that includes a housing assembly, a lubricant and a differential assembly. The housing assembly defines a differential cavity with a lubricant sump into which the liquid lubricant is received. The differential assembly is mounted in the differential cavity for rotation about a rotational axis and includes a differential case, a ring gear, a gear set and an oil shield. The differential case has a body, which defines a gear cavity into which the gear set is received, and a flange that is coupled to the body and includes a flange face. The ring gear is coupled to the flange. The oil shield is coupled for rotation to the differential case and covers a least a radially outward portion of the circumferentially discontinuous features so that they do not directly contact the liquid lubricant in the lubricant sump when the differential assembly rotates about the rotational axis.
