Abstract
The invention relates to a one-shell spring suspension arm formed of sheet metal for a wheel suspension of a motor vehicle, including a first end section for connection to a chassis carrier, a second end section for wheel-side connection, and a width-expanded section for supporting a spring, which is arranged between the two end sections and defines a trough having upwardly projecting flanks. In order to enable optimized wheel suspension by distributing the forces and torques to spatially distanced connections, or articulated-connection points, while achieving a relatively low component weight and favorable manufacturing costs, the invention provides that a spiral is integrally formed in the width-expanded section of the spring suspension arm as a spring seat and that a connection section for connecting a shock absorber is formed between the spiral and the second end section.
