The invention relates to a double-row wheel bearing unit for a vehicle, comprising an axle journal fixed to the vehicle, and a wheel hub bearing a wheel flange rotatably mounted on said axle journal by means of two rows of rolling bodies spaced axially apart. In order to adapt the loading capacity of the rows of rolling bodies to the respective load conditions, the two rows of rolling bodies have different rolling circle diameters respectively adapted to the highest expected load.

The bearing arrangement, in order to enable an improved connection of the wheel hub to the rotating joint and better adjust a prestress of the roller bearing, has a face of the axle stub of the wheel hub with a spur gearing element which is non-rotatably connected to a corresponding spur gearing element of the joint body of the rotating joint. The spur gearing elements are disposed at least partially radially and axially beneath the roller bearing, and that the inner bearing ring is connected to a means for the axial tolerance compensation between the inner bearing ring and the counter-surface of the joint body.

Wheel bearing (1) has sensor (15) for measuring rotational or angular movements of a wheel with wheel bearing flange (2) and roller bearing (4) attached thereto. Peripheral inner ring (7) has encoder ring (9) serving as transducer. To ensure a reliable operating mode even under the influence of dirt and rust and to be able to attach and detach the wheel bearing (1) with ease, sensor (15) is attached parallel to its radial reading direction (24) on radial contact face (23), pointing to the plane of encoder ring (9), of wheel bearing flange (2). Furthermore, sheet-metal part (16) is fitted on fixed outer ring (6) of roller bearing (4), which sheet-metal part (16) covers at least the reading area of sensor (15) and encoder ring (9) and serves, in circumferential terms, as contact face for sensor (15).

The invention relates to a wheel hub having a central section and a radial section which is radially connected to the central section, a bearing section which axially protrudes from the central section and is used to receive a wheel bearing, and an axially opposing receiving section for receiving a brake disk and a wheel rim. Holes for receiving wheel nuts are formed in the radial section. In order to produce an especially light wheel hub that can withstand all operating loads and provides a brake disk with a secure abutment surface under all operating conditions, the wheel hub has recesses at least between some holes, the recesses fully penetrating the wall of the radial section of the wheel hub, and at least one reinforcing means is embodied on the radial end of the wheel hub.

The invention relates to a sealed radial rolling bearing, in particular a wheel bearing for a motor vehicle, which substantially comprises an outer bearing ring and an inner bearing ring and a plurality of rolling bodies which roll between the bearing rings and are held with uniform spacing relative to one another by means of a bearing cage. Here, in each case one radially arranged sealing element extends between the bearing rings at each side at a distance axially from the rolling bodies, said sealing element having one or more sealing lips which are connected to the outer bearing ring and some into contact with a centrifugal ring which is connected by means of a press fit to the inner bearing ring. According to the invention, the centrifugal ring of the sealing element is composed of a simple cold-formable steel sheet and has a galvanic corrosion prevention coating with zinc-containing constituents, the cathodic protective action of which can prevent both rust infiltration at the press fit between the centrifugal ring and the inner bearing ring and the onset of corrosion in the region of contact between the sealing lips and the centrifugal ring.

The invention relates to a sealing arrangement (2) that seals at least one radial intermediate space (21) between at least one inner bearing ring (3) and at least one outer bearing ring (5). Said sealing arrangement (2) comprises at least one first support (17) that supports at least one elastic seal (18) and a second support (19) which supports at least one encoder (10) located outside the intermediate space (21). The encoder (10) is radially oriented towards at least one sensor (14) that is disposed above the encoder (10) in a radially outward direction.

The invention relates to a seal arrangement for sealing off at least one radial interspace between at least one bearing ring which can rotate and at least one rotationally fixed bearing ring. The seal arrangement is provided with at least a first carrier, the first carrier carrying at least one resilient seal and being fixed to a rotationally fixed bearing ring, and a second carrier, the second carrier being fixed to the bearing ring that can rotate and carrying at least one encoder. The encoder has an outwardly oriented circumferential surface in the shape of a truncated circular cone.

Wheel-bearing and brake-disk unit designed such that forces (deformations) when the rim is being screwed on largely avoid resulting axial run-out in the brake disk. The bearing flange to which the rim and pot-shaped part of the brake disk are attached has first fastening openings and a larger diameter in the regions of the first openings and a smaller diameter between adjacent first openings. The pot-shaped part of the brake disk has second fastening openings and a larger diameter in the regions of the second openings and a smaller diameter between adjacent second openings.

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).
