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. The distance between adjacent extensions is less than the diameter of each ball. |
