ABSTRACT:
An outboard constant velocity universal joint for a steered wheel of a vehicle includes a one-piece, structurally-integral inner race and first shaft and a one-piece, structurally-integral outer race and second shaft. The inner race has an outer surface of partially spherical configuration. The outer race has a closed end and an open end with an inner surface of partially-spherical configuration and of constant radius extending from the open end to the closed end. The inner and outer races fit closely together in the manner of a ball and socket without any cage between the surfaces thereof. A cage or retainer is located in the closed end of the outer race with a convex outer surface substantially equal in length to the radius of the inner surface of the outer race. The cage has a plurality of fingers extending only into end portions of the grooves of the inner race. The fingers have outwardly-extending flanges extending into grooves of the outer race. The diameter of the first shaft does not exceed the diameter of the bearing balls so that the first shaft can be received in outer end portions of grooves of the outer race during assembly of the inner and outer races.
