    Abstract: A wheel bearing arrangement of a vehicle axle is disclosed. The wheel bearing arrangement includes a wheel bearing, which contains at least two rolling element rows, for supporting a wheel hub which can be driven by a drive element. The rolling elements of the wheel bearing are guided in races of a stationary outer ring, the rotating wheel hub, and a separate inner ring which is allocated to the wheel hub. In the assembled state, the wheel hub of the wheel bearing arrangement and the drive element are operatively connected via gearing. The inner ring has a radially stepped inner contour, the inner contour having two diameters which differ from one another, and are received in a complementarily designed receiving area of the wheel hub. The position of the inner ring is fixed on the end face by a rolling riveted collar of the wheel hub.

  • Publication number: 20150343841
    Abstract: A roller riveting assembled hub bearing unit, the inner ring (2) of which has a radially elevated region for resolving production problems during the roller riveting process. For such a hub bearing unit, an optimal sensor arrangement, such as that required for rotational speed detection for example, is to be provided without having to accept disadvantages with rotational speed detection, sealing and strength optimization of the inner ring (2). A signal emitter (5) is arranged axially flush in a flat manner on the side of the vehicle on a higher area of the inner ring (2). A cover (8) axially covers the wheel hub (18) on the vehicle side. The detection of the movement of the signal emitter (5) takes place in the axial direction through the cover (8). To accommodate the sensor, the cover (8) comprises a protrusion (15) which is axially opposite the signal emitter (5), which can be arranged radially within the outer ring (3) either partially or completely.

  • Publication number: 20110293213
    Abstract: An angular ball bearing, in particular wheel bearing, with at least two rows of load-bearing rolling bodies and a hollow-cylindrical section arranged between two rolling body inner raceways. Inner rims are arranged at transitions from the hollow-cylindrical section to the rolling body inner raceways. The ball bearing is impactproof. This is achieved in that an annular element is arranged in, for example pressed into, the hollow-cylindrical section, axial force is transmitted between the rolling bodies of adjacent rows of rolling bodies, and a Brinelling of the raceway outlets and of the raceways is reduced or even prevented. The annular element may be an independent component or an annular element which is integrated in the outer ring, for which instructions regarding the required conditions are provided.
