Abstract
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), ea…
