Constant velocity universal ball joint
First Claim
1. A constant velocity universal ball joint for a wheel hub/universal joint unit comprising:
- a wheel hub, a universal ball joint with an inner and outer joint part, a bearing assembly arranged on the wheel hub and tensioned relative thereto by the outer joint part of the universal joint;
an unfastenable or disconnectable connection between the wheel hub and universal joint including a bolt/nut assembly comprising at least two parts;
said outer joint part and the inner joint part having longitudinally extending ball tracks which are arranged radially opposite one another and torque-transmitting balls which are held in said radially opposite one another ball tracks and are held in one plane in individual windows of a ball cage positioned between the outer joint part and the inner joint part and which, upon articulation of the joint, are moved on to the angle-bisecting plane, with the outer joint part, at a wheel hub-turned end, being closed by a base part and the inner joint part being connected to a shaft, said base part being insertable from the wheel hub-turned end into an aperture at the wheel hub-turned end and forming one of the parts of the bolt/nut assembly for holding the wheel hub, the bearing assembly and the outer joint part relative to one another, said base part being unfastenable from an abutment means on said outer joint part for said base part in the axial direction and said outer joint part on the one hand, and one of said base part and said wheel hub, on the other hand, each of the base part, wheel hub and outer joint part having form locking means mutually engaging one another in a rotational direction and that the base part connected to the outer joint part permanently extends into a space inside the outer joint part occupied temporary by the ball cage or the inner joint part during assembling of the joint.

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.
