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.
