Abstract
A shield for sealing a joint includes a first end, a second end and an annular shell. The first end is adapted for axial retention on an outer joint part, where the outer joint part is rotationally coupled to an inner joint part. The second end is adapted for abutting contact with a semi-spherical portion of the inner joint part. The annular shell extends between the first end and the second end thereby providing a seal for the joint. Also provided is a grease shield sealing system for a direct torque flow constant velocity joint.
Claims20
A shield for sealing a joint comprising:
- a first end adapted for axial retention on an outer joint part, the outer joint part being rotationally coupled to an inner joint part;
- a second end adapted for abutting contact with a semi-spherical portion of the inner joint part;
- and
- an annular shell extending between said first end and said second end.
A grease shield sealing system for a direct torque flow constant velocity joint comprising:
- an inner joint part having a semi-spherical portion toward an axial open end of the direct torque flow constant velocity joint;
- an outer joint part having an external surface and rotationally coupled to said inner joint part;
- and
- a shield extending between a first end and a second end, said first end axially retained on said external surface of said outer joint part, and said second end in abutting contact with said semi-spherical portion of said inner joint part.
A grease shield sealing system for direct torque flow constant velocity joint comprising:
- an inner joint part having a semi-spherical portion toward an axial open end of the direct torque flow constant velocity joint;
- an outer joint part having an external surface and rotationally coupled to said inner joint part, the outer and inner joint parts defining a cavity;
- a semi-rigid shield having a first portion, a second portion, and a third portion, said first portion axially retained on said external surface of said outer joint part, said second portion in abutting contact with said semi-spherical portion of said inner joint part, and said third portion delineating a transition between said first portion and said second portion;
- and
- a membrane seal having an outer periphery and an inner periphery, wherein said outer periphery is radially coupled to said third portion and said inner periphery is coupled to said inner joint part to provide secondary sealing,
- wherein said semi-spherical portion is defined by an outer surface area of said inner joint part that is bounded between a smaller circle and a larger circle being axially separated and located within one hemisphere of a sphere having a center coinciding with a geometric center of the direct torque flow constant velocity joint.
