Abstract: An axial fixation of a splined shaft connection, particularly between a hub of a constant velocity joint and a shaft, whereby a splined end of the shaft is to be inserted in and extracted out of a splined bore of the hub from one side thereof. A snap ring is in contact with a stop surface of the shaft and a holding surface of groove in the hub. The snap ring and the holding surface are situated in the extraction direction axially behind the carrying zone of the splines, whereby the hub is provided with an opening following the holding surface having a radius which is greater than the radius of the radially-opposed portion of the shaft by an amount which is at least equal to the radial width of the snap ring.

Abstract: A constant velocity universal joint has an outer joint member with a bore therethrough and an inner joint member within the bore. A plurality of torque transmitting elements, such as balls, are positioned within opposed substantially axially extending grooves formed in the facing surfaces of the inner and outer joint members. The balls are retained in a ball plane by a cage which has an outer spherical surface guided within a correspondingly shaped cylindrical surface in the bore and an inner concave surface which is guided upon a spherical surface of a control body mounted as a separate component on the inner joint member. The centers of the outer and inner cage spherical surfaces are equidistant on opposite sides of the ball plane. The control body has a plurality of control elements positioned between adjacent balls and a plurality of extensions extend from said control elements toward the outer spherical surface of the cage and project beyond the ball plane.
