Abstract

A wheel bearing assembly of a vehicle is provided. A hub is mounted via a roller bearing arrangement in a wheel carrier. The hub has a driving flange with a bearing surface which is perpendicular to the axis of rotation of the wheel, optionally with the intermediate positioning of a brake disk, such that the bearing surface of the driving flange describes a plane that intersects the roller bearing arrangement. The hub forms or supports an inner ring of the roller bearing arrangement, and an outer ring of the roller bearing assembly is held in the wheel carrier. A support structure for the driving flange is guided around the roller bearing arrangement on the outside of the wheel bearing assembly, facing away from the vehicle body and wheel carrier. As a result, a wheel insertion depth in the order of zero or a few millimeters may be achieved.
