Abstract: A torsion bar spring arrangement, particularly a stabilizer arrangement, for a double-track vehicle, has at least one prestressed spring element which limits the introduction of force into the torsion bar spring or the stabilizer to a value defined by the prestressing force of the spring element, in which case the spring element acts as an overload protection such that, when a force is introduced which significantly exceeds the prestressing force, the torsion bar spring arrangement would be damaged without this spring element. The torsion bar spring can have a divided construction and the spring element can be clamped in between the two parts of the torsion bar spring, in which case these two parts of the torsion bar spring can be mutually rotatable by way of an actuator. Preferably, the torsion bar spring parts each have a driving device which is clamped by way of the spring element between two stops which, for the first torsion bar spring part, are fixedly connected with the housing of the actuator ad,for the second torsion bar spring part, are connected with its control element.
