Abstract
A constant velocity universal ball joint for a wheel hub/universal joint unit has a bearing assembly arranged on the wheel hub and tensioned relative thereto by the outer joint part of the universal joint. The joint has an unfastenable connection between the wheel hub and universal joint includes a bolt/nut assembly. The outer joint part and the inner joint part have longitudinally extending ball tracks which are arranged radially opposite one another. The tracks contain torque-transmitting balls which, in turn, are held in one plane in individual windows of a ball cage positioned between the outer joint part and the inner joint part. Upon articulation of the joint, the balls are moved on to the angle-bisecting plane with the outer joint part, at one end, closed by a base part and the inner joint part connected to a shaft. The outer joint part includes a base part which, from the wheel hub end, is insertable into an aperture at the wheel hub end and which forms one of the parts of the bolt/nut assembly for tensioning the wheel hub. The bearing assembly and the outer joint part relative to one another, and which base part, after having been connected to the outer joint part, permanently extends into a free space inside the outer joint part required for assembling the joint and thus cannot be connected to the outer joint part until the joint is completely assembled.
