Abstract
An angle-limiting ring coupled to an interconnecting shaft of a driving axle coupled to a fixed ball type outer constant velocity joint. The angle-limiting ring prevents the overarticulation of the joint at any time when the driving axle is not fully assembled into a rear wheel drive system. This prevents the loss of the ball bearings contained within the joint associated with this overarticulation. A snap ring may also be installed on the interconnecting shaft that allows the positive retention of the interconnecting shaft into the inner race.
Claims22
A driving axle comprising:
- a plunging type inner constant velocity joint assembly;
- a fixed ball type outer constant velocity joint assembly, said fixed ball type outer constant velocity joint assembly having an outer race having an inner region, an inner race substantially coupled within said inner region, a plurality of ball bearings positioned between said outer race and said inner race, and a cage used to position each of said plurality of ball bearings;
- an interconnecting shaft coupled between said plunging type inner constant velocity joint assembly and said fixed ball type outer constant velocity joint assembly;
- and
- an angle-limiting ring coupled to said interconnecting shaft, wherein said angle-limiting ring is capable of limiting the articulation of said interconnecting shaft to a first angle relative to a centerline, wherein said first angle is approximately between fifteen and forty degrees relative to said centerline, said centerline being defined as extending longitudinally along a symmetrical length and through said outer race.
A fixed ball type outer constant velocity joint assembly of a driving axle for use in a rear wheel drive system comprising:
- an outer race having an inner region;
- an inner race substantially coupled within said inner region;
- a plurality of ball bearings positioned between said outer race and said inner race;
- a cage used to position each of said plurality of ball bearings;
- an interconnecting shaft coupled to said inner race;
- and
- an angle-limiting ring coupled to said interconnecting shaft, wherein said angle-limiting ring is capable of limiting the articulation of said interconnecting shaft to a first angle relative to a centerline during assembly or disassembly of the driving axle from the rear wheel drive system, wherein said first angle is approximately between fifteen and forty degrees relative to said centerline, said centerline being defined as extending longitudinally along a symmetrical length and through said outer race.
