Abstract
A differential assembly for a transfer case or other motor vehicle application comprehends a pair of side gears which flank a centrally disposed spider driven by an input member and having a plurality of spokes or shafts and bevel pinion gears disposed thereon. An annular member retains the bevel gears on the spider. In a first embodiment, the annular member is retained on the spider by cooperating elongate slots in the member which receive the shafts of the spider and a snap ring which extends about the circumference of the annular member. In an alternate embodiment, the pinion gears include projecting spherical surfaces which are complementary to and seat within spherical recesses on the inner surface of the annular member.
