ABSTRACT:
A constant velocity universal joint for large articulation angles, consisting of an outer joint part comprising a cavity and longitudinally extending outer ball running grooves opening towards the cavity; an inner joint part positioned inside the cavity and comprising longitudinally extending inner ball running grooves corresponding to the outer ball running grooves; torque transmitting balls running in outer and inner ball running grooves associated with one another; and a cage which is arranged between the outer joint part and the inner joint part, which is provided with windows for accommodating the balls and which comprises two opposed apertures having generating central axes which extend transversely to the joint axis. With reference to the above joint it is proposed that the outer joint part is provided with radially opposed slots with surface-normal central axes which coincide with the central axes of the apertures, that at the inner joint part there are arranged two radially opposed journals which extend transversely to the joint axis and comprise central axes which coincide with the central axes of the slots and pass through the slots, that the cage is substantially annular in shape relative to the central axes of the apertures and that there is provided a two-arm joint yoke which, by means of its arms, is secured to the journals.
