Problems solved by technology

[0009] In the design by finite element method and life estimation, the above-mentioned manufacturing-induced deviation makes prediction difficult
Based on the fatigue stress evaluation obtained from experiments, the aforementioned manufacturing-related deviations have a negative effect on the life to be statistically proven, since a higher risk factor must be taken into account for results with severe deviations

Embodiment Construction

[0052] figure 1 An axle beam 10 is shown. The axle carrier 10 is designed as an axle of a commercial vehicle. The commercial vehicle can be, for example, a truck or a bus.

[0053] Each side of the axle beam 10 has a first (lower) axle beam shell 12 , a second (upper) axle beam shell 14 and a shaft truncated 16 . The first and second axle beam shells 12 and 14 are in particular designed as axle beam half shells. The first axle beam shell 12 and the second axle beam shell 14 are connected to one another (in particular welded) along the longitudinal axis A of the axle beam 10 . The axle stub 16 is joined, in particular welded, to one end of the interconnected axle beam shells 12 and 14 . A brake flange 18 of a disc brake or drum brake can be welded onto the axle beam 10 . A plug-in shaft, not shown, can extend through the axle beam 10 .

[0054] The axle beam 10 is connected to the chassis (not shown) of the motor vehicle, for example via welded brackets 20 . In this resp...

Abstract

The invention relates to an axial component for a commercial vehicle and a method for producing the same. The present disclosure relates to the axle beam (10), in particular an axle bridge, for a motor vehicle, preferably a commercial vehicle. The axle beam (10) has a first axle beam shell (12) and a second axle beam shell (14) which is connected, in particular welded, to the first axle beam shell(12) in order to configure a tubular body (32). The tubular body (32) has an inner circumferential face (26) with a plurality of flat sections (34) which form a non-round cross section of the tubularbody (32). The axle beam (10) has a reinforcing component (22) which has a non-round cross section, is arranged within the tubular body (32), and bears at least partially against the flat sections (34) of the inner circumferential face (26) of the tubular body(32).

Description

technical field [0001] The invention relates to an axle carrier of a motor vehicle, in particular a commercial vehicle, and a method for producing the axle carrier. Background technique [0002] The axle beam of a motor vehicle must be connected to the chassis of the car. For the chassis connection, the carrier can be welded to the axle beam, for example by fillet welding. Alternatively or additionally, it is possible to weld metal strips to the axle beam for a form-fit chassis connection. In this case, the metal strips can be connected to the axle beams, for example, by means of seams produced by fusion welding. The metal strip can then be milled in order to ensure a defined width of the cross section for the form-fit mounting of the chassis connection. [0003] Known methods involve welding brackets and / or metal strips, which are disadvantageous. [0004] Both the corner seams of the welded brackets and the metal strips applied by spot welding reduce the load-bearing c...
