Abstract
To achieve a low wheel spring rate at low wheel loads and a higher wheel spring rate at higher wheel loads, each wheel of a rear-wheel suspension is equipped with a torsion bar spring which cooperates by way of a pressure rod connected with the wheel carrier. An adjusting device is connected with the torsion bar spring to act upon an additional spring element which can take up a controlled elastic position or a blocked position.
