  • Publication number: 20140208593
    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: 8714830
    Abstract: A wheel bearing unit which has an outer ring, one or two inner rings and load-transmitting rolling elements arranged between the two rings. An orbitally formed shoulder of a wheel hub is provided for the pre-stressing of the wheel bearing unit via the inner ring, and a toothed ring which has an outward-facing radial tooth system is arranged on the inner ring, as is usual in wheel bearing units with all-wheel drive capability. The wheel bearing unit has a small axial width which benefits the handling characteristics of a vehicle by attaching the toothed ring to the orbitally formed shoulder and transmitting the drive torques via this attachment. Welding and a plastically formed tooth system on the orbitally formed shoulder are proposed as examples of such fastening.

  • Publication number: 20130318796
    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.

  • Publication number: 20130283954
    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: 8560196
    Abstract: A mounting device for mounting a driven and/or a drivable wheel of a vehicle. The mounting device makes it possible to measure a drive torque or a drag torque that acts between a wheel and a driveshaft. The torque is transmitted from the driveshaft to the wheel by radial teeth on a bearing inner ring where there is a pressure-sensitive measuring element to measure axial forces as a characteristic of the particular effective torque. In addition, a device to control the distribution of the drive and drag torques acting on the driveable wheels of a vehicle is disclosed. To measure the drive and drag torque distribution, there is a sensor unit on each drivable wheel to measure the torque acting on each wheel.

  • Patent number: 8523447
    Abstract: A wheel bearing arrangement that has a wheel hub, which is operatively connected to an outer ring by way of rolling elements and a wheel flange. The wheel flange, together with a protective ring forms a first gasket. The protective ring surrounding the outer ring of the wheel hearing arrangement. This approach is of particular interest for non-driven wheel bearing arrangements in which the side of the wheel bearing facing the vehicle can be protected by a cover used on the vehicle side.

  • Patent number: 8444322
    Abstract: A face spline of a toothed rim running in a circumferential direction around a rotation axis on a wheel-bearing arrangement for a driven wheel hub. The face spline is provided for play-free engagement with the counter-spline, facing the face spline and the teeth of the face spline have a wedge-like embodiment such that the geometrical lines of the face spline meet centrally at a common point on the rotation axis and the teeth thus run in the radial direction on the rotation axis.

  • Patent number: 8439572
    Abstract: The wheel bearing assembly connects a journal section of the hub and a joint body. The wheel bearing assembly has an adapter section is connected to a joint cap, a journal section connected to a wheel hub. A separate inner ring is located on the journal section. The adapter section and the journal section intermesh by means of end gearing. The assembly also has a tensioning element that mutually braces the adapter section and the journal section under an overall pre-tension, the end gearing being braced by a first pre-tension along a first force path A between the adapter section and the journal section and the inner ring being braced by a second pre-tension along a second force path B between the adapter section and the journal section. At least some sections of the first and second force paths A and B are parallel.

  • Publication number: 20110241416
    Abstract: A rotary forming method for producing a rivet flange of a wheel hub on which a wheel bearing is mounted. A rivet flange is formed from a cylindrical part of a wheel huh by a hobbing tool oriented along a direction of the axis of rotation of the wheel hub. The method keeps material stresses low and accurately adjusts the preload of the bearing. For this purpose, first rotating rolling elements of at least one first row of rolling elements of the tool form the rivet flange. Axes of rotation of the first rolling elements form a first angle with the axis of rotation of the rolling bearing during the riveting operation, ensuring uniformity on the entire circumference of the cylindrical part of the wheel hub using a smaller deformation force while allowing the rolling bearing to be temporarily preloaded by a holding element even before the cold forming process.
