Benefits of technology
The invention provides an improved wheel bearing for a vehicle that can be easily installed and maintained. The wheel bearing is made up of two individual roller bearings that are axially clamped onto a support shaft. This design reduces the need for expensive maintenance and allows for easy replacement of individual components. The cold-formed stop on the support shaft ensures a consistent and reliable pre-stressing of the roller bearings. The wheel bearing can also be produced as a closed unit, with all elements prefabricated and installed in the vehicle. Overall, the invention provides a cost-effective and efficient solution for wheel bearings in vehicles.
Problems solved by technology
In this design it would be difficult, though, to keep any lubricant in said roller bearings, so that the roller bearings frequently, usually after a driven distance of 40,000 kilometers would have to be relubricated, which leads to expensive maintenance measures for relubricating such roller bearings.
Additionally, the roller bearings are subject to increased soiling and wear and tear, which could lead to increased fuel consumption, for example.
Ultimately, in such roller bearings the pre-stressing at such wheel bearings cannot be adjusted in order to reduce any axial play and thus keep it steady over an extended life span.
The production of such wheel bearings may be more expensive by up to 150%, though, than the production of the wheel bearing variants mentioned first.

Abstract
A wheel bearing for a utility vehicle, having a sheath-shaped support shaft in which an axle of the utility vehicle can be concentrically accepted, a wheel hub, and a first roller bearing as well as a second roller bearing for the wheel hub to roll over the support shaft, with the second roller bearing being axially pre-stressed on the sheath-shaped support shaft via a stop, cold-formed from the support shaft, against the first roller bearing.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from German Patent Application No. DE 10 2011 076 275.2, filed May 23, 2011 which application is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The invention relates to a wheel bearing for a utility vehicle, the utility vehicle, and a method for producing the wheel bearing.BACKGROUND OF THE INVENTION[0003]Wheel bearings are arranged in the center of a wheel and serve in the vehicle for the rotational fastening of the wheel at the vehicle chassis. At the vehicle, the wheel bearing separates rotational components, such as the wheel hub, from fixed components, such as the wheel suspension. The wheel bearing transfers forces and momentums from the road to the undercarriage and vice versa.BRIEF SUMMARY OF THE INVENTION[0004]One object of the invention is to provide an improved wheel bearing for a vehicle.[0005]The invention suggests providing a wheel bearing of the type mentioned a...
