Abstract

See full text

A differential assembly is provided to include a two-piece differential case, a differential gearset disposed in a gearset chamber formed in the differential case, and a ring gear. An interlocking feature mechanically interconnects the first and second case members of the two-piece differential case and define a continuous differential case weldment surface. The ring gear is mounted on the differential case such that its ring gear weldment surface is aligned with the differential case weldment surface. A welded joint along the aligned weldment surfaces creates a weldment junction connecting the case members and the ring gear to each other.
