Abstract
A wheel bearing unit comprises an inner ring and an outer ring. The outer ring is mounted rotatably and is arranged concentrically with respect to the inner ring. The inner ring serves to receive a wheel and the outer ring serves for fastening to a wheel support of a motor vehicle. The wheel bearing unit has, between the inner ring and the outer ring, a first ball row and a second ball row which is arranged parallel to the first ball row. A follower is arranged in a rotationally fixed manner with respect to an outer side of the inner ring between the first ball row and the second ball row. The follower is connected directly or indirectly to a rotor of an electric machine in a torque-transmitting manner.
