Four pinion differential

A differential for use on a vehicle comprising a one piece differential housing defining pinion shaft openings extending radially through said housing and a bearing surface for rotatably supporting said housing on one end, a coverplate fastened to the end of said housing defining a bearing surface for rotatably supporting said plate and housing, a ring gear fastened to said differential housing adapted for being driven by a drive pinion, a pair of side gears in said housing rotating on a common axis of rotation with said ring gear and differential, a plurality of pinion gears in said housing engaging said side gears, an integral shaft structure including, pinion shafts including a cross shaft extending diametrically through two of the openings in said housing supporting a pair of said pinion gears, a pair of stub shafts fixedly engaging the center of said cross shaft and extending radially from said cross shaft through two other of the opening in said housing and supporting a second pair of pinion gears, a bolt extending axially through said stub shafts and diametrically through said cross shaft locking said cross shaft axially and retaining said shafts in fixed non-rotating positions in said housing thereby defining an integral shaft structure.
