Embodiment Construction

[0042] figure 1 This was previously described in detail in the "Background Art" section. The invention is suitable for wheel bearings on steered and non-steered wheels: figure 2 A wheel bearing unit 1 according to the invention is shown, which is arranged as a wheel bearing structure rotatable about an axis A and is driven by fine tooth splines 36 or similar form-locking elements. The wheel bearing unit 1 has an outer ring 2 , two inner rings 3 , two first rows 4 of balls 5 and two second rows 6 of balls 5 . In bearing radial plane E 1 A pair consisting of a first row 4 and a second row 6 is arranged on each side. Furthermore, the wheel bearing unit 1 has a flange body 7 which is equipped with a fastening element 8 in the form of a flange 37 . Wheel bolt 9 is fixedly installed in the flange 37.

[0043] The inner ring 3 is fixedly mounted on the flange body 7, and a bead-shaped flange 7a formed radially outward from the flange body 7 and pressed against an inner ring 3 c...

Abstract

A wheel bearing unit (1) is embodied in a four-rowed angular contact ball bearing form.

Description

technical field [0001] The invention relates to a wheel bearing unit of an angular contact ball bearing structure, which has at least two rows of balls in the first row surrounding the center line of the wheel bearing unit and two rows of balls in the second row parallel to the first row, one of which is formed by the second row of balls. A first pair consisting of one of the first columns and one of the second columns and a second pair consisting of one of the first columns and one of the second columns are mounted oppositely. Background technique [0002] A wheel bearing unit of this type is shown in GB 206,606. Such wheel bearing units are no longer adapted to the requirements of modern automobiles, especially when the wheel bearings are mounted on the automobile. Up to the moment when the present invention is made, professionals have no choice for wheel bearings on vehicles with medium and heavy loads. Tapered Roller Bearings. The advantage of using tapered roller bear...
