Abstract
An axle assembly that includes a differential case which is rotatable about an axis, a pair of side gears that are disposed within the differential case, a spacer ring and a cross pin. The spacer ring is disposed between the side gears. The cross pin is fixed to one of the differential case and the spacer ring and extends through the spacer ring. The aperture in the spacer that receives the cross pin may be larger than the cross pin so that the spacer ring can control end play of the side gears independently of the cross pin.
Claims10
A differential assembly, comprising:
- a case having first and second case apertures communicating with an internal chamber;
- a pair of output shafts having end segments disposed within said chamber;
- a gearset disposed in said chamber for transmitting drive power from said case to said output shafts while permitting speed differentiation therebetween and including a pair of laterally-spaced side gears coupled to said end segments of said output shafts;
- and
- a spacer pin assembly having a spacer ring, a cross pin and a fastener, said spacer ring is disposed in said chamber between said side gears and has first and second spacer apertures alignable with said first and second case apertures, said cross pin is disposed within said aligned first and second case apertures and said first and second spacer apertures, and wherein said fastener secures said cross pin to said case.
