However, this results in the disadvantages already mentioned above, namely that air bubbles occur when welding such galvanized individual parts and thus lead to the formation of pores in the weld seam, which in turn leads to a shortened weld seam life

Embodiment Construction
[0029] figure 1 and 2 An exemplary embodiment of an axle bearing 1 according to the invention for a vehicle not further illustrated here, in particular a motor vehicle such as a passenger car, is shown. The axle bearing has two longitudinal beams 2 oriented essentially in the direction of travel F, each of which has a joint 3 at opposite ends in the direction of travel F, at which joints the axle bearing is, for example, via rubber-metal bearings It is connected to the body, however, this is not shown in detail here.
[0030] The two longitudinal beams 2 can be produced, for example, from ungalvanized steel material, for example formed by ungalvanized tailor-welded sheet metal components, although this is likewise not further illustrated here. Alternatively, however, the side member 2 can also be produced in one piece from steel material, for example by casting.
[0031] The two longitudinal beams 2 are connected transversely to the direction of travel F and thus viewed in ...

The invention relates to an axle support for a vehicle, in particular for a motor vehicle, comprising two longitudinal supports (2) and at least one transverse support (4) interconnecting the two longitudinal supports (2), wherein the at least one transverse support (4) or at least one of the transverse supports (4) is formed as a multi-part tailored blank component part and is fixedly welded via its lateral transverse support connection regions (13, 14) arranged opposite in the longitudinal direction of the transverse support to the respective assigned longitudinal support (2), and wherein the transverse support (4) is coated with a surface coating (17) as a protective layer, in particular with a zinc layer. According to the invention, the lateral transverse support connection regions (13, 14) are each formed by an uncoated, in particular non-zinc-plated, one-part or multi-part sheet metal component part (7, 8), wherein the transverse support middle region adjoining the two lateral transverse support connection regions (13, 14) is formed by a one-part or multi-part sheet metal component part (9), which is coated, at least on its underside facing towards the road in the assembled state of the axle support (1), at least in regions with the preferably metal and / or chemically or galvanically applied surface coating (17), in particular a zinc layer.
Description
technical field [0001] The invention relates to an axle bearing for a vehicle, in particular for a motor vehicle, according to the preamble of claim 1 and to an axle bearing for a vehicle according to the preamble of claim 11 Method for an axle bearing of a vehicle, in particular for a motor vehicle. Background technique [0002] Such axle bearings—also known as auxiliary supports or subframes—are known and generally consist of two longitudinal beams, which in the mounted state of the axle bearing are oriented substantially in the longitudinal direction of the vehicle, which They are connected to each other by at least one transverse beam oriented substantially in the transverse direction of the vehicle. In shaft bearings made of steel materials, the surface protection is usually provided by cathodic dip painting. If the area of the axle bearing, in particular the front cross member of the axle bearing in the direction of travel, is in the radiation range of the particle...
