Abstract
The invention relates to a single-shell spring control arm formed of sheet metal for a wheel suspension of a motor vehicle, with upwardly directed side limbs connected to one another by a base, with a first end section for connection to a chassis girder, with a second end section for wheel-side connection, with a spring receiving section, which is located between the two end sections and has a spring support surface formed on the base, and with a damper receiving section formed between the spring receiving section and the second end section for connecting a shock absorber. In order to achieve at relatively low component weight and favorable manufacturing costs improved stiffness with respect to high axle loads, the invention provides that a U-shaped constriction is formed between the spring support surface and the damper receiving section, which constriction extends in the base and in the side limbs.
