Abstract: A constant velocity joint comprises an outer joint part with outer ball tracks and an inner joint part with inner ball tracks. An outer ball track and an inner ball track respectively form a pair of tracks with one another; in each, a torque-transmitting ball is guided. The torque-transmitting balls are accommodated in a ball cage with circumferentially distributed cage windows. In any angular position of the constant velocity joint an opening angle is formed between an outer tangent to the outer ball track and an inner tangent to the inner ball track. At an articulation angle of zero degrees the opening angle is greater than zero degrees. A central articulation angle range is defined with articulation angles less than fifteen degrees. The opening angle increases by at least two degrees within the central articulation angle range, and is less than twelve degrees for all articulation angles within the central articulation angle range.

Abstract: An outer ring shaft portion which is extended integrally from an end face of an outer ring of a constant velocity joint is fittingly inserted into an inside hole in a hub shaft of a wheel hub, so that the wheel hub and the constant velocity joint are coupled to each other. Internal splines and external splines are formed on an inner circumferential surface of the inside hole in the hub shaft and an outer circumferential surface of the outer ring shaft portion in such a manner as to mesh with each other. Side face splines are formed on end face of the hub shaft and an end face of the outer ring of the constant velocity joint. The wheel hub and the constant velocity joint are connected together in such a manner that torque can be transmitted therebetween.
