Title: A DIFFERENTIAL AND DRIVE PINION ASSEMBLY
Abstract:
An improved mount for a drive pinion to drive a gear differential includes a tapered bearing (54, 58) mounted at both inner and outer ends of the drive pinion (24). The tapered bearing (54) at the inner shaft portion (55) supports the drive pinion in a housing (50) which abuts an outer race of a bearing (48) which supports one of the side gears (46). The use of the tapered bearing (54) at the inner end of the drive pinion provides smaller packaging requirements for the overall assembly, and provides a more secure mount for the inner end of the drive pinion.
