Abstract
A differential assembly including a casing which rotates about a first axis, the casing having an internal cavity; an elongate cylindrical cross pin which rotates with the casing about the first axis, the cross pin extending along a second axis through the cavity, the second axis substantially perpendicular to the first axis; at least one pinion gear disposed within the cavity and about the cross pin, the pinion gear rotatable about the second axis; and a pair of side gears disposed within the cavity and in meshed engagement with the pinion gear, the side gears rotatable about the first axis. A cross pin retention element is disposed about the cross pin. The cross pin and the retention element are fixed against substantial relative movement therebetween along the second axis, and the retention element is disposed adjacent the pinion gear. The movement of the retention element relative to the casing along the second axis is restricted, whereby the cross pin is retained in the casing.
