Embodiment Construction

[0048] figure 1 The truck hub assembly shown in includes a bearing assembly 1 according to the invention attached to a steel hub element 2 fixed to the wheel suspension (not shown). A wheel rim 3 and a brake disc 4 are mounted on the bearing assembly 1 . The hub element 2 may comprise a tube end, which may have any cross-sectional shape, such as circular, square, triangular, conical, pyramidal, etc.

[0049] The bearing assembly 1 is of the double row tapered roller type with two outer retainers 5,6 and two inner retainers 7,8. A set of tapered rollers 9 and 10 are accommodated between the retaining rings 5, 7 and 6, 8, respectively, and these tapered rollers are held in a known manner by cages 11, 12, respectively.

[0050] In order to achieve proper performance of the bearing assembly 1, a certain axial preload should be applied to the tapered roller bearing. The preload is applied to the inner retainers 7 , 8 by means of nuts 13 which are screwed onto the threads 14 of t...

Abstract

The unit has an outer bearing ring (1) and an inner bearing ring (2) set concentrically and movable relative to each other. At least one of the bearing ring comprises two metal components (9,10) coupled side-by-side by a connecting unit (11). The connecting unit includes brazed and / or soldered connections (14,15) and a welded connection (16).

Description

technical field [0001] The invention relates to a bearing assembly comprising: at least two bearing parts, the bearing surfaces of which are movably supported on each other; and an auxiliary element connected to one of said bearing parts. Background technique [0002] Such bearing assemblies are well known in various fields. As an example, reference may be made to a truck hub bearing assembly comprising such a bearing assembly. One of the retainer components of the bearing is usually attached to the hub, which is attached to the axle of the truck or trailer. The bearings are held in place by nuts threaded onto the external threads of the hub. [0003] The connection between the bearing and the hub is subject to various loads and is therefore prone to fatigue degradation. Therefore, advanced materials such as high-grade steel must be used in this area to obtain acceptable fatigue life. However, this poses extremely severe restrictions on the choice of materials. For exam...
