Abstract
A stabilizer bar for a chassis of a motor vehicle comprises a torsion spring portion and two arms bent away from the torsion spring portion; wherein the arms each comprise a formed end portion with a through-opening and a tubular portion, wherein the torsion spring portion comprises a hardened structure with a strength of at least 1000 MPa; and wherein the formed end portions comprise a hardened structure with a strength of at least 800 MPa. A process of producing a corresponding stabilizer is further disclosed.
Claims10
A tubular stabilizer bar for a chassis of a motor vehicle, comprising:
- a torsion spring portion and two arms bent away from the torsion spring portion,
- wherein the arms each comprise a formed end portion with a through-opening and a tubular portion,
- wherein the torsion spring portion comprises a hardened structure with a strength of at least 1000 megapascals (MPa),
- wherein the formed end portions comprise a hardened structure with a strength of at least 800 MPa, and
- wherein the arms, in the tubular portion, each comprise a partial region with a low strength that is smaller than 0.7 times the strength of the torsion spring portion.
