Abstract
The invention relates to a single-shell spring control arm, for a wheel suspension of a motor vehicle, comprising a first end portion for attaching to a chassis beam a second end portion for attaching on the wheel side, and an increased-width portion which is arranged between the two end portions, and which comprises a spine having flanks projecting therefrom and which defines a spring seat for supporting a spring. In order to attain high component rigidity and a wheel suspension which is optimized with regard to loads, the invention proposes that inwardly deformed surface parts are formed on the flanks, the longitudinal edges of which surface parts are spaced apart from one another along their entire length so that the increased-width portion has a C-profile-shaped cross-sectional profile, and in that a connection portion for attaching a shock absorber is formed between the spring seat and the second end portion.
