A homokinetic ball turning joint has a joint outer part (1a) with ball tracks (6a) distributed around its circumference that extend substantially in the longitudinal direction and a joint inner part (11a) with ball tracks (13a) distributed around its circumference that extend substantially in the longitudinal direction. The tracks (6a, 13a) are arranged in pairs, lie opposite each other in the radial direction and carry together a torque transmitting ball (14a). A cage (7a) receives the ball (14a) in windows (15a) distributed around the circumference, retains it in a common plane and when the axes of the joint outer part (1a) and joint inner part (11a) are bent towards each other, it guides the balls (14a) onto the angle bisecting plane. The joint outer part (1a) has inner surfaces (5a) with no undercuts located between the individual ball tracks (6a), when viewed in the axial direction. Retaining elements linked to the joint outer part (1a) form cage guiding surfaces (16a) which prevent the cage (7a) from moving out of the joint outer part (1a) in the axial direction. At least two independent retaining elements (9a) for the cage (7a) are inserted into the joint outer part (1a), each between two ball tracks (6a), and are soldered to the joint outer part (1a).

A constant velocity universal ball joint comprising an outer joint part with substantially longitudinally extending circumferentially distributed ball tracks; an inner joint part with substantially longitudinally extending circumferentially distributed ball tracks, the outer and inner joint part tracks being arranged in pairs radially opposite one another and jointly receiving a torque transmitting ball; a cage which receives the balls in circumferentially distributed windows which holds them in a common plane and which, upon articulation of the axes of the outer and inner joint parts, guides the balls on to the angle-bisecting plane, the outer joint part being produced with surfaces between the individual ball tracks, which, if viewed in the axial direction, constitute undercut-free inner surfaces; at least three securing elements for the cage being inserted into the outer joint part between two neighboring ball tracks, respectively, being connected to the outer joint part and forming cage contact and cage guiding faces which counter-act an axial movement of the cage out of the outer joint part, the balls being able to move between the securing elements; said securing elements are formed by wedges, independent of one another, which are axially inserted into an annular gap between the outer joint part and an outer face of the cage, which are fixed to the outer joint part at a desired position and which, with a set axial play, hold the cage in the outer joint part by means of contact points.
