A wheel hub, which has a central section and a radial section that is radially connected to the central section, a bearing section which axially protrudes from the central section and is used to receive a wheel bearing, and an axially opposing receiving section for receiving a brake disk and a wheel rim. Holes for receiving lug bolts are formed in the radial section. In order to produce an especially light wheel hub that can withstand all operating loads and provides a brake disk with a secure abutment surface under all operating conditions, the wheel hub has recesses at least between some holes, which fully penetrate the wall of the radial section of the wheel hub, and at least one reinforcing element is embodied on the radial end of the wheel hub.

Wheel hub comprising axial recesses formed between the holes for lug bolts

The radial antifriction bearing has an outer bearing ring, an inner bearing ring and roller bodies, which are arranged between the bearing rings, are held at uniform distances from one another in the peripheral direction by a bearing cage. The roller bodies are discs that each have two parallelly arranged lateral surfaces which are symmetrically flattened from a spherical basic shape. In order to prevent edge stresses between the discs and the raceways, at least the raceway in the inner bearing ring, on its outer edge areas, transition into a logarithmically decreasing profile.

Radial antifriction bearing, particularly a single-row grooved antifriction bearing or angular contact antifriction bearing

A radial roller bearing, which is a single-grooved ball bearing. The bearing bodies are spherical disks with two symmetrical, parallel lateral surfaces from a spherical base shape. The bearing has a larger contact surface of the spherical disk in relation to the bearing body tracks thereof, as well as, an increased number of bearing bodies. One part of the width of the disks, between the lateral surfaces thereof, is larger than the distance between the inner side of the external bearing ring and the external side of the inner bearing ring, but equal to or smaller than the width of the bearing body tracks. Also, the use of the disks in the bearing takes place according to an eccentric mounting method where the disks are arranged in a transversal manner in the bearing body tracks and are arranged on top of each other in relation to the lateral surfaces thereof.

The invention relates to a wheel hub having a central section and a radial section which is radially connected to the central section, a bearing section which axially protrudes from the central section and is used to receive a wheel bearing, and an axially opposing receiving section for receiving a brake disk and a wheel rim. Holes for receiving wheel nuts are formed in the radial section. In order to produce an especially light wheel hub that can withstand all operating loads and provides a brake disk with a secure abutment surface under all operating conditions, the wheel hub has recesses at least between some holes, the recesses fully penetrating the wall of the radial section of the wheel hub.
