Problems solved by technology

[0012] The implementation of this method is complex since it requires a technical monitoring cycle and the associated electronic components
Furthermore, it is disadvantageous that due to cold deformation, the deformation of the protrusions and thus stresses occur, which generally require additional manufacturing work in order to eliminate these stresses
Such riveting devices are also subject to large variations in the required clamping force due to large forming deviations

Embodiment Construction

[0030] The wheel bearing arrangement 1 has a wheel hub 2 comprising a wheel-side fastening flange 3, on which a non-illustrated friction body, ie a brake disc and a wheel, are fastened by means of connecting elements 4, for example screws. lock up.

[0031] The hub 2 , as is common for drive shafts, can be connected in a rotationally fixed manner to a drive cardan shaft via an internal toothing 5 in its interior.

[0032] In the case of a hub for a non-driven shaft, which is not shown, the hub has no internal torque-transmitting elements and can be completely solid or have recesses.

[0033] Arranged on the hub 2 is a two-row angular contact rolling bearing 6 , which has a two-piece inner ring 7 and an outer ring 8 , between which two rows of spherical rolling bodies 9 are arranged.

[0034] The end 10 of the hub 2 opposite the fastening flange 3 is connected materially to a flange ring 11 , that is to say by means of welding and preferably by laser welding on the inner circu...

Abstract

The invention relates to a bearing unit, preferably, a wheel bearing unit (1) for a motor vehicle, comprising a hub (2) provided with a wheel-sided securing flange (11), whereon an angular contact anti-friction bearing (6), which comprises at least one inner ring (7) and an outer ring (8), is arranged. In order to produce the bearing unit (1) and to operate it in an economical manner, and also to prevent, for example, deformation and tensions characteristic of known roller riveting units, the securing flange (3) is connected in a material fit to the flange ring (11) in relation to the end (10) of the hub (2), which clamps at least the inner ring (7) to the hub (2).; The invention also relates to a method for producing a bearing unit (1), preferably, a wheel bearing unit for a motor vehicle, comprising a hub (2) which is provided with a wheel-sided securing flange (3) whereon an angular contact anti-friction bearing (6) comprising at least one inner ring (7) and an outer ring (8), is arranged, by means of a device (13) which exerts a clamping force (F) on the bearing unit (1).

Description

technical field [0001] The invention relates to a bearing arrangement, preferably a wheel bearing arrangement for a motor vehicle, having a hub with a wheel-side hub flange, on which an angular contact rolling bearing with at least one inner ring and an outer ring is arranged. The invention also relates to a method for mounting such a bearing arrangement by means of a device for applying a clamping force to such a bearing arrangement. Background technique [0002] Wheel bearings are particularly heavily loaded components of wheel suspensions on vehicle chassis which have to withstand very different operating loads. [0003] An important part of the wheel bearing assembly is its bearing inner ring, which is fixed axially after the heat treatment and cutting steps with a correspondingly high clamping force of 50 kN to 120 kN depending on the bearing size. [0004] Known devices and methods for setting such an axial clamping force are the use of joint bells, a nut on the wheel...
