摘要:
A wheel bearing arrangement which has at least two rows of rolling bodies for mounting a wheel hub which can be driven with the wheel bearing arrangement by a drive element. The wheel hub is connected to the drive element, and the wheel hub and the drive element engage positively into one another via a pair of mutually corresponding spur toothings. In the wheel bearing arrangement, a value of greater than three is obtained for a ratio of the diameter of a toothing reference circle of the spur toothing in the wheel bearing arrangement to the rolling body row spacing of the at least two rows of rolling bodies.

The wheel bearing joint unit having an inner ring that sits on a hub of the wheel bearing joint unit. The inner ring is axially retained on the hub using a collar that is formed from the hub. The collar is provided with a toothing which meshes with a corresponding opposite toothing on a joint part. The toothing and the opposite toothing are braced against each other by a screw which rests on the hub and engages into a thread on the joint part. The joint has two axial projections, one which has the toothing to engage the toothing on the collar and another with the threading to engage the screw. These two projections are spaced apart by a groove to provide flexibility.

The invention relates to a wheel bearing joint unit comprising at least one inner ring that sits on a hub of the wheel bearing joint unit. Said inner ring is axially retained on the hub by means of a collar that is formed from the hub. The collar is provided with a toothing which meshes with a corresponding opposite toothing on a joint part. The toothing and the opposite toothing are braced against each other with the aid of at least one screw element which rests on the hub and engages into a thread on the joint part.

The invention relates to a face spline of a toothed rim running in the 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.

The invention relates to a spur toothing on at least one coupling element for transmitting torques about a rotational axis, said spur toothing axially engaging with a corresponding mating cutting. The face cutting is provided with teeth from a material of the coupling element that has been plastically shaped in an at least partially non-cutting manner.

The invention relates to a wheel bearing unit having at least one outer part, having at least one inner part, and having at least two rows of rolling bodies between the outer part and the inner part, wherein in each case at least one inner raceway is formed on the outer part and in each case at least one outer raceway is formed on the inner part for the rolling bodies of one row. A ratio of the diameter of the reference circle of at least one row of the wheel bearing unit to the diameter of the rolling bodies of the respective row is greater than the numerical value six. The row spacing between the rows corresponds to at most 1.65 times the diameter of the rolling bodies.

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.
