Abstract
The wheel bearing joint unit having an inner ring that sits on a hub of the wheel bearing joint unit. The inner ring is axially retained on the hub using a collar that is formed from the hub. The collar is provided with a toothing which meshes with a corresponding opposite toothing on a joint part. The toothing and the opposite toothing are braced against each other by a screw which rests on the hub and engages into a thread on the joint part. The joint has two axial projections, one which has the toothing to engage the toothing on the collar and another with the threading to engage the screw. These two projections are spaced apart by a groove to provide flexibility.
Claims6
A wheel bearing joint unit comprising:
- at least one inner ring which is seated on a hub of the wheel bearing joint unit, the inner ring being held axially on the hub by means of a collar which is formed out of the hub, and the collar having a toothing in engagement with a corresponding mating toothing on a joint component, and with the toothing and the mating toothing being braced against one another by means of a screw element which is supported on the hub and engages into internal threads on the joint component, wherein a first axially projecting extension is formed on the joint component, with the first extension having the internal threads and a second axially projecting extension is formed on the joint component, with the second extension projecting axially in the same direction as the first extension, the first extension and the second extension are formed in a materially integral fashion with the joint component, and an axial groove formed in the joint component, the groove positioned radially between the first extension and the second extension so as to radially separate the mating toothing from the first extension.
