Abstract
A vehicle drive axle is provided that includes a housing having a longitudinal portion defining a cavity. An axle shaft is supported within the cavity for rotation about an axis. The cavity is at least partially filled with oil. A plurality of spaced apart noncontiguous projections extend from the axle shaft in a direction transverse to the rotational axis. During rotation of the axle shafts, the projections extend into the oil within the cavity and splash the oil onto the upper portion of the axle housing. Increased heat dissipation is achieved by dispersing the oil throughout the cavity, and in particular the upper portion of the axle housing, where it radiates into the surrounding environment.
