Torsion spring arrangement for a wheel suspension arrangement of a motor vehicle, and wheel suspension arrangement for a wheel of an axle of a motor vehicle

A torsion spring assembly for a wheel suspension of a motor vehicle, comprising:

• two torsion bars arranged coaxially one inside another and also a spring element, which is arranged with radial distance to the two coaxial torsion bars, is aligned in an axial direction of the torsion bars, and can be mounted on a motor vehicle body via a bearing position, wherein an outer hollow-cylindrical torsion bar viewed in a radial direction can be mounted on a side of the motor vehicle body and is connected in a rotationally-fixed manner to an output lever fastenable on a wheel guiding element and the inner torsion bar viewed in the radial direction (r) is connected in a rotationally-fixed manner to the outer torsion bar and in a rotationally-fixed manner to the spring element via a coupling;
• and
• wherein the bearing position mounting the spring element on the motor vehicle body side interacts with a first actuator for effective spring length adjustment of the spring element and a second actuator for the pre-tension adjustment of the spring element, wherein the spring element is mounted via a spring element bearing on the coupling, which is designed in such a way that a translational deflection, exclusively oriented in the tangential direction (t), is applied to the spring element, and in that the bearing position mounting the spring element on the motor vehicle body side is designed as a plain bearing displaceable in relation to the spring element in the axial direction (a).
