ABSTRACT:
In a vehicle wheel mounting and driving assembly, power from a vehicle drive unit is transmitted through a differential gear system to a first universal joint assembly and then to a second universal joint assembly mounted in the wheel of the vehicle. The wheel hub is formed with an inner bearing ring which has a diameter greater than the outer diameter of the outer joint member of the first universal joint assembly of the differential gear system. The vehicle wheel is formed with a central bore having a diameter which is greater than the outer diameter of the outer joint member of the second universal joint assembly of the wheel. The first universal joint assembly is connected to the differential gear system with its outer joint member axially affixed to the differential gear system by a radially expandable spring ring and with longitudinal gear teeth on a trunnion of the outer joint member, thereby enabling the first universal joint assembly to be axially removed from the differential gear system, while also being in rotative driving engagement therewith. As a result, disassembly of the entire mechanism may be readily accomplished from the exterior of the vehicle wheel without requiring dismounting of the wheel from the vehicle.
