A wheel bearing unit which has an outer ring, one or two inner rings and load-transmitting rolling elements arranged between the two rings. An orbitally formed shoulder of a wheel hub is provided for the pre-stressing of the wheel bearing unit via the inner ring, and a toothed ring which has an outward-facing radial tooth system is arranged on the inner ring, as is usual in wheel bearing units with all-wheel drive capability. The wheel bearing unit has a small axial width which benefits the handling characteristics of a vehicle by attaching the toothed ring to the orbitally formed shoulder and transmitting the drive torques via this attachment. Welding and a plastically formed tooth system on the orbitally formed shoulder are proposed as examples of such fastening.

The invention relates to an anti-friction bearing comprising a first bearing race, a second bearing race and a plurality of anti-friction bodies that are located between the first bearing race and the second bearing race. According to the invention, the anti-friction bearings are arranged in several rows, which are asymmetrical in the longitudinal direction of the anti-friction bearing in relation to any plane that runs perpendicularly to said longitudinal direction of the anti-friction bearing.

Asymmetrical triple-row anti-friction bearing

The invention relates to an anti-friction bearing comprising a first bearing race, a second bearing race and a plurality of anti-friction bodies that are located between the first bearing race and the second bearing race. According to the invention, the anti-friction bodies are arranged in several rows and the pitch diameters of at least two rows differ.
