Abstract:
1. A grease shield sealing system for a direct torque flow constant velocity joint comprising: an inner joint part having an outer surface, said outer surface having a semi-spherical portion toward an axial open end of the direct torque flow constant velocity joint, said semispherical portion radially located on an outer axial side of inner ball tracks formed on said inner joint part; an outer joint part having an external surface and rotationally coupled to said inner joint part; 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 such that said second end seals a fluid within the constant velocity joint; and a resilient portion included with said shield and located between said first end and said second end, where said resilient portion provides spring-like abutment against said shield such that said second end of said shield seals said fluid within said constant velocity joint.
