  • Patent number: 9868320
    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: 20160245340
    Abstract: The invention relates to a seal arrangement for a wheel bearing, inserted between a first bearing part and a second bearing part of the wheel bearing, which includes a pre-seal designed as a centrifugal disk and a seal set having sealing lips and a reinforcement. The seal set is attached to the first, torsionally fixed bearing part by a reinforcement which is surrounded at least partially by an elastic sealing material. A radial edge of a centrifugal disk engages with play in an opening that is delimited radially by the sealing material, said centrifugal disk being fixed to the second bearing part via a radial leg and including a catch groove. Together with the seal set, the centrifugal disk forms a seal labyrinth.

  • Publication number: 20160040714
    Abstract: A rolling bearing cage 10 with two rings 1,2 connected by webs 9, wherein webs 9 provided with bifurcations 8 are used to solve the problem of reducing weight while simultaneously ensuring increased load rating, wherein said webs 9 permit adjacent rolling bodies to be arranged very close to one another. Furthermore, a plurality of identical cages 10 are prevented from tangling in each other when said cages are heaped in large quantities. Overall, the cage 10 allows a more compact design for inclined ball bearings and also reduces their moment of friction.

  • 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.
