  • Patent number: 10072711
    Abstract: A method for producing a composite rolling bearing (1) having a bearing flange (3) and at least one rolling bearing (4, 5) held on the bearing flange (3) by an inner ring (6, 7). In order to be able to fix the inner ring (7) on the bearing flange (3) with axial preloading without expansion, the inner ring (7) is acted upon by a holding-down device (23) that radially holds down the inner ring (7) and is preloaded against the inner ring (7) by a regulated axial force (F), and, by way of an advancing cone (21) introduced radially on the inside axially into the bearing flange (3), material (11) present on the bearing flange (3) is displaced radially towards the outside into a recessed formation (15, 16) in the inner ring (7).

  • 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.

  • Patent number: 9676232
    Abstract: A wheel hub (1) having a radially extending wheel flange (17) which has fastening holes (3), having a cylindrical projection which extends from the wheel flange (17) axially on the vehicle side and which serves for at least partially receiving a rolling bearing, and having a centering device which is mounted axially on the wheel side. A high rigidity of the wheel hub (1) and/or of the wheel bearing unit is realized with little material usage. One possibility arises by the centering device of a wheel hub being regarded as the product of the compromise between rigidity and possible material removal. In this regard, a particular arrangement of the webs that form the centering device is provided which leads to a particularly advantageous solution, specifically by virtue of the webs (7) being oriented in the same radial direction (A, B) as the fastening holes (3) of the wheel flange (17).

  • Patent number: 9625277
    Abstract: An ABS encoder arrangement for a driven wheel bearing unit, with a multi-pole ring, a sensor device with a sensor head, and an annular cap element that has an annular wall portion which shields a cap interior against the exterior. The annular wall section extends through an intermediate region lying between the multi-pole ring and an end face of the sensor head. An extension concentric with the axis of rotation of the multi-pole ring and extending axially over a circumferential area of an articulated shaft head is connected to the annular wall section on a side facing away from the multi-pole ring. In the end portion of the extension facing away from the multi-pole ring and extending over the articulated shaft head, the extension forms a circumferential profile that radially stiffens the extension and forms an annular edge which extends into a circumferential groove of the articulated shaft head and forms a channel cross-section open to the outside.

  • 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.

  • Patent number: 9377055
    Abstract: A wheel bearing arrangement having an outer ring (12), an inner ring (13), and a seal arranged between the outer ring (12) and the inner ring (13) for the purpose of sealing off a rolling chamber, wherein, in the rolling chamber, rolling bodies (10) roll in a load-bearing manner on raceways of the outer ring (12) and of the inner ring (13), wherein the cover element (32) has a fastening region (28) for the fastening of the cover element (32) radially at the outside to the outer ring (12). It is sought to further improve the encoder protection in a wheel bearing arrangement of said type by virtue of the cover element (32) having a collecting channel (27) which surrounds a joint bell housing (19) and thereby protecting the encoder (14) of the wheel bearing arrangement against fouling.

  • 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.

  • Patent number: 8956054
    Abstract: An inner raceway (3) having a rolling element raceway facing radially outward, for an angular contact bearing arrangement, and particularly an angular ball bearing arrangement, where a cylindrical surface which is situated at the furthest outward position radially is included as a seal seat. Such inner raceways are used in wheel bearing units, for example, which have an orbital rivet bond, which in turn can also form an end-face gearing (7). The orbital rivet bond and the axial extension (8) of the inner raceway form an annular gap (20) which leads to a configuration where a decoupling of loads from the inner raceway (3) prevents an undesired deformation of the same. In addition, advantages result from the sealing of the region of the orbital rivet bond and/or the end-face gearing (7) thereof.

  • Patent number: 8826542
    Abstract: In summary, the invention relates to a method for forming an end-side toothing arrangement of a roiling bearing, in particular a wheel bearing. The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.
