Abstract
A method of producing a stabilizer (10) of a motor vehicle, such that the stabilizer includes a torsion bar (11) and longitudinal links (12, 13). The longitudinal links (12, 13) are in each case connected to the torsion bar (11) by welding, and the longitudinal links (12, 13) and the torsion bar (11) are heat-treated before welding. Each longitudinal link (12, 13) is welded at one end to the torsion bar (11) on both sides, in each case, by a respective multilayer weld seam (14), and each weld seam (14) is made with unequal widths such that the width of the weld seam (14) adjacent to the torsion bar (11) is shorter than its width adjacent to the respective longitudinal link (12, 13).

A method of producing a stabilizer (10) of a motor vehicle such that the stabilizer includes a torsion bar (11) and longitudinal links (12, 13), and the longitudinal links (12, 13) being, in each case, connected to the torsion bar (11) by welding, the method comprising:
- heat-treating the longitudinal links (12, 13) and the torsion bar (11) before welding and, after the heat treatment, welding the longitudinal links to the torsion bar,
- welding each longitudinal link (12, 13), at one end, to the torsion bar (11) on both sides, in each case, by respective multilayer weld seams (14), and
- making each of the weld seams (14) with unequal widths such that a width of the weld seam (14) adjacent to the torsion bar (11) is shorter than a width of the weld seam adjacent to the respective longitudinal link (12, 13).
A stabilizer (10) for a motor vehicle, the stabilizer comprising:
- a torsion bar (11) and longitudinal links (12, 13),
- the longitudinal links (12, 13) being connected to the torsion bar (11) in each case by welding, and each of the longitudinal links (12, 13) being welded to a section of the torsion bar (11) on both sides by a respective multilayer weld seam (14), and
- each weld seam (14) being made with unequal widths such that a width of the respective weld seam (14) adjacent to the torsion bar (11) is shorter than its width adjacent to the longitudinal link (12, 13) concerned.
A method of producing a motor vehicle stabilizer that includes a torsion bar and first and second longitudinal links, the first and the second longitudinal links are each connected to the torsion bar by welding, the method comprising:
- heat-treating the first and the second longitudinal links and the torsion bar before welding the first and the second longitudinal links to the torsion bar, and each of the first and the second longitudinal links has an inner side and an opposite outer side and the torsion bar has opposed first and second ends;
- welding the first end of the torsion bar to the first longitudinal link with a multilayer weld seam formed on each of the inner and the outer sides of the first longitudinal link, and welding the second end of the torsion bar to the second longitudinal link with a multilayer weld seam formed on each of the inner and the outer sides of the second longitudinal link;
- forming the multilayer weld seam between the first end of the torsion bar and the outer side of the first longitudinal link such that a width of the multilayer weld seam along the torsion bar is shorter than a width of the multilayer weld seam along the outer side of the first longitudinal link, and forming the multilayer weld seam between the first end of the torsion bar and the inner side of the first longitudinal link such that a width of the multilayer weld seam along the torsion bar is shorter than a width of the multilayer weld seam along the inner side of the first longitudinal link;
- and
- forming the multilayer weld seam between the second end of the torsion bar and the outer side of the second longitudinal link such that a width of the multilayer weld seam along the torsion bar is shorter than a width of the multilayer weld seam along the outer side of the second longitudinal link, and forming the multilayer weld seam between the second end of the torsion bar and the inner side of the second longitudinal link such that a width of the multilayer weld seam along the torsion bar is shorter than a width of the multilayer weld seam along the inner side of the second longitudinal link.
