ABSTRACT:
A constant velocity joint is provided with an outer part, in the inner surface of which tracks are provided, an inner part, on the outer surface of which corresponding tracks are provided, and with balls in a pivotable cage located in the space between the outer part and the inner part. Taking as a basis the particular axial displacement, caused by the torque, of the outer part and the inner part in relation to the cage, this displacement depending mainly on the amount of the respective axial clearances of the pairs of centering surfaces and/or on the brinelling of the window support surfaces by the balls in the running-in phase and also on the elastic flexibility of the parts, the running-in wear and the thermal expansion. The outer surface of the inner part and the inner surface of the cage or the inner surface of the outer part and the outer surface of the cage have clearance therebetween so that the inner or outer part is axial displaced relative to the cage, toward one side, whereby the tracks of the inner part do not run as mirror images to the tracks of the outer part in relation to the ball plane.
