ABSTRACT:
This transmnission differential of the type comprising a two-piece differential case defined by a cup-shaped case member and a side member integrally formed with a ring gear to thereby increase the strength of the ring gear and case. The side member is bolted onto the cup-shaped case member. The pinion gears of this invention are not formed with a spherical portion at its interface with the case because the present invention provides a novel design that does not require the spherical radii because the two-piece case can easily be assembled with resort to these additional machining requirements. The pinion shaft is secured against rotation by a pin trapped in a bore formed in the case when the ring gear side member is mounted to the cup-shaped case member. Because the cup-shaped case member is formed with a flat mating surface, the present invention does not require eyebrows formed into the case for drilling points where the bolt is received in the case. The two-piece design also eliminates the need for windows in the case. Therefore, the present invention reduced manufacturing costs while providing a stronger differential case.
