The invention relates to a sealing arrangement (1, 16) comprising at least one seal (2, 17) and a spinning ring (3, 21 ). Said spinning ring (3, 21 ) is provided with a first hollow cylindrical section, a second hollow cylindrical section (5, 28) in the first section (4, 23), which is disposed concentric to the first section (4, 23), and a disk-shaped ring section (8, 27) that extends at an angle to the first section (4, 23). The first section (4, 23) and the second section (8,27) are embodied monolithically on the spinning ring, at least one elastic sealing lip (10, 19) of the seal (2, 17) resting against the first section (4, 23).
摘要:
A wheel bearing unit which has at least one outer part, at least one inner part and at least two rows of rolling bodies between the outer part and the inner part. One inner raceway is formed on the outer part and one outer raceway is formed on the inner part for the rolling bodies of each row. The wheel hub has internal toothing, which projects radially inwards in the direction of the rotational axis, for engaging external toothing on a drive pin. The internal toothing of the hub is rotationally fixedly coupled to the outer raceway. The ratio of the diameter dz of a tip circle of the internal toothing to the bearing width bL of the outer part is greater than 0.9.

The invention relates to a bearing arrangement (1) of a wheel hub (2) of a motor vehicle drivable by a rotating joint (5), comprising a double-row roller bearing (11) mounted on the wheel hub (2), the bearing being provided with at least one separate inner bearing ring (17) which with a face (24) thereof protrudes axially beyond the end of an axle stub (18) of the wheel hub (2), wherein the roller bearing (11) is axially prestressed by a counter-surface (25) of a joint body (7) of the rotating joint (5), the surface acting on the face (24) of the separate inner bearing ring (17). In order to enable an improved connection of the wheel hub to the rotating joint and better adjust a prestress of the roller bearing, it is provided that a face of the axle stub (18) of the wheel hub (2) comprises a spur gearing element (3) which can be non-rotatably connected to a corresponding spur gearing element (4) of the joint body (7) of the rotating joint (5), wherein the spur gearing elements (3, 4) are disposed at least partially radially and axially beneath the roller bearing (11), and that the inner bearing ring (17) is connected to a means (27) for the axial tolerance compensation between the inner bearing ring (17) and the counter-surface (25) of the joint body (7).

The invention relates to a wheel hub (1) comprising a central section (2) and a radial section (3) which is radially connected to the central section, a bearing section (4) which axially protrudes from the central section (2) and is used to receive a wheel bearing, and an axially opposing receiving section (20) for receiving a brake disk and a wheel rim. Holes (5, 6, 7, 8) for receiving wheel nuts are formed in the radial section (3). 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 (1) comprises recesses (9, 10, 11, 12, 13) at least between some holes (5, 6, 7, 8), said recesses fully penetrating the wall of the radial section (3) of the wheel hub (1), and at least one reinforcing means is embodied on the radial end (28) of the wheel hub (1).

The invention relates to a method and assembly device (23) for producing a rotary joint between a drive element (1, 21) and a flange (2). According to the invention, the drive element (1, 21) and the flange (2) are screwed together at least by means of a first nut (22) and a bolt (7, 35) of the drive element (1, 21) at least until the bolt (7, 35) is drawn axially into a bore (5) in the flange (2) by the rotation of the first nut (22) and until the drive element (1, 21) attains a final position in relation to the flange (2).

The invention relates to a unit (1 ) comprising a wheel bearing (4) and at least one vehicle-sided fixed support (3). The wheel bearing (4) comprising at least one outer part (5) which is rigidly fixed to at least one bearing seat (12, 14) which is embodied as an axial passage (25) of a sheet metal moulded part of the support (3), and at least one end section (11, 13) of the outer part (5) is surrounded in a radial and supple manner, at least in the proximity of said passage such that the end section (11, 13) engages in an axial manner behind the support (3).
