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 wheel suspension for a wheel of an axle of a motor vehicle, comprising a suspension spring acting between the motor vehicle body and a wheel guiding element, wherein the suspension spring is designed in the form of a torsion spring arrangement 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 the axial direction of the torsion bars and can be mounted on the motor vehicle body via a bearing position, wherein the outer hollow-cylindrical torsion bar viewed in the radial direction can be mounted on the motor vehicle body side 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 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,
• wherein the spring element is mounted via a spring element bearing on the coupling, which is designed in such a way that exclusively a translational deflection oriented in the tangential direction 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 fixed bearing.
