Abstract:
A clutch assembly includes an inner race, an outer race and a plurality of roller elements positioned radially therebetween. The clutch assembly also includes a cage assembly, a seal and a retaining ring. The cage assembly includes a skeleton coupled to a spring ring having a plurality of radially extending guides arranged to circumferentially space apart each roller element in alignment with cam surfaces formed on the outer race. The guides are resiliently deformable to allow concurrent engagement of each roller element with both the inner and outer races. The seal engages an inner surface of the outer race and an outer surface of the inner race, and is positioned axially outboard of the roller elements. The retaining ring is positioned within ring grooves formed on each of the inner and outer races to restrict movement of the cage.
