Abstract

The wheel bearing assembly connects a journal section of the hub and a joint body. The wheel bearing assembly has an adapter section is connected to a joint cap, a journal section connected to a wheel hub. A separate inner ring is located on the journal section. The adapter section and the journal section intermesh by means of end gearing. The assembly also has a tensioning element that mutually braces the adapter section and the journal section under an overall pre-tension, the end gearing being braced by a first pre-tension along a first force path A between the adapter section and the journal section and the inner ring being braced by a second pre-tension along a second force path B between the adapter section and the journal section. At least some sections of the first and second force paths A and B are parallel.
