DIFFERENTIAL ASSEMBLY

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. 本发明提供了种差速器组件，该差速器组件包括两件式差速器箱体、布置在形成于差速器箱体中的齿轮组室中的差速齿轮组、以及环形齿轮。互锁特征将两件式差速器箱体的第箱体构件与第二箱体构件机械地互连并且限定连续的差速器箱体焊接表面。环形齿轮安装在差速器箱体上并且安装成使得环形齿轮的环形齿轮焊接表面与差速器箱体焊接表面对准。沿着对准的焊接表面的焊接接头形成将箱体构件与环形齿轮彼此连接的焊接接合部。
