Abstract
A torsion spring bar system for a wheel suspension of a motor vehicle includes on each vehicle side a torsion spring bar which is oriented transversely to the vehicle longitudinal center and acts on each wheel guide element of the wheel suspension with variable pretension via an output lever positioned outwards with respect to the vehicle longitudinal center. The torsion spring bar is acted upon by an actuator with a torsional moment. The torsion spring bars on both vehicle sides are coupled to one another at their axially adjacent ends in the vehicle longitudinal center via at least one additional torsion spring element.
