Abstract
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.

Claim 1
Independent Claim
320 words
A wheel mounting and driving assembly for the wheel of a motor vehicle comprising: a differential gear system through which power is delivered from drive means of said vehicle to said wheel; a first universal joint assembly adjacent said differential gear system; plug connection means connecting said first universal joint assembly with said differential gear system to be driven by said drive means of said vehicle, said plug connection means being constructed to enable said first universal joint assembly to be disconnected from said differential gear system by axially withdrawing said first universal joint assembly therefrom in the direction of said wheel; a second universal joint assembly in driven engagement with said first universal joint assembly; a bearing assembly rotatively mounting said wheel on said vehicle including an outer bearing ring supported on said vehicle and an inner bearing ring affixed with said wheel; said second universal joint assembly including an outer joint member arranged within an inner bore of said inner bearing ring and adapted to be placed in driving engagement therewith to transmit driving power to said wheel; gear teeth means extending in the axial direction of said wheel interconnecting said inner bearing ring and said outer joint member of said second universal joint assembly in direct driving engagement while permitting relative axial displacement therebetween; and releasable locking means axially releasably locking said inner bearing ring and said outer joint member of said second universal joint assembly together; said wheel having a central bore with a diameter D R which is larger than the outer diameter D 1 of said outer joint member of said second universal joint assembly, said inner bore of said inner bearing ring having a diameter D 2 which is larger than the outer diameter D 3 of the outer joint member of said first universal joint assembly; said mounting and driving assembly being thereby capable of disassembly from the exterior of said wheel.

A wheel mounting and driving assembly for the wheel of a motor vehicle comprising: a differential gear system through which power is delivered from drive means of said vehicle to said wheel; a first universal joint assembly adjacent said differential gear system; plug connection means connecting said first universal joint assembly with said differential gear system to be driven by said drive means of said vehicle, said plug connection means being constructed to enable said first universal joint assembly to be disconnected from said differential gear system by axially withdrawing said first universal joint assembly therefrom in the direction of said wheel; a second universal joint assembly in driven engagement with said first universal joint assembly; a bearing assembly rotatively mounting said wheel on said vehicle including an outer bearing ring supported on said vehicle and an inner bearing ring affixed with said wheel; said second universal joint assembly including an outer joint member arranged within an inner bore of said inner bearing ring and adapted to be placed in driving engagement therewith to transmit driving power to said wheel; gear teeth means extending in the axial direction of said wheel interconnecting said inner bearing ring and said outer joint member of said second universal joint assembly in direct driving engagement while permitting relative axial displacement therebetween; and releasable locking means axially releasably locking said inner bearing ring and said outer joint member of said second universal joint assembly together; said wheel having a central bore with a diameter D R which is larger than the outer diameter D 1 of said outer joint member of said second universal joint assembly, said inner bore of said inner bearing ring having a diameter D 2 which is larger than the outer diameter D 3 of the outer joint member of said first universal joint assembly; said mounting and driving assembly being thereby capable of disassembly from the exterior of said wheel.
Claim 3
Dependent Claim
68 words
An assembly according to claim 1 wherein said plug connection interconnecting said first universal joint with said differential gear system comprises trunnion means formed on the outer joint of said first universal joint assembly, longitudinal gear teeth means formed on said trunnion means and locking ring means interposed between said trunnion means and said differential gear system for fixing said outer joint member thereto in an axial direction.
Claim 4
Dependent Claim
16 words
An assembly according to claim 2 wherein said locking ring means comprise a wire spring ring.
Claim 5
Dependent Claim
23 words
An assembly according to claim 1 wherein said first universal joint assembly is constructed so as to be secured against axial disassembly thereof.
