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).

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.

Abstract: The invention relates to a method for calibrating a sensor system of at least one measuring bearing for a bearing installation, said method being used to adjust individual measured values of an individual bearing installation using representative reference values of a reference installation.

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.

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.

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.
