Claims20
A barrier membrane assembly for sealing a constant velocity joint assembly, comprising:
- at least one selectively expandable and contractible barrier membrane body,
- wherein the barrier membrane body has no openings therethrough and may selectively expand and contract in response to operational pressures acting against the barrier membrane body.
A constant velocity joint assembly having a first end and a second end, comprising:
- an outer race;
- an inner race supported within the outer race;
- a shaft engaging the inner race;
- a rolling element disposed between the inner race and the outer race;
- at least one selectively expandable and contractible barrier membrane operatively mounted on the outer race, the barrier being responsive to changes in pressure during operation of the constant velocity assembly.
