- Stabilizers of the type mentioned are also referred to as torsion bar springs. Stabilizers or torsion bar springs are generally known in automotive engineering, in particular chassis construction, for use as roll stabilizers.
- stabilizers can be arranged between the wheels on an axle of a vehicle. If the wheels on an axle are deflected alternately, stabilizers distribute the axle load and thus ensure an even axle load distribution. As a result, the driving behavior of a vehicle can be positively influenced in such a way that, for example, the coefficient of adhesion of the wheels arranged on an axle can always be kept almost identically at a good level.
- the free ends of known stabilizers can usually each be arranged and / or supported der on a separate component, for example a wheel-guiding element, such as a wheel carrier or a wheel-guiding link, via Pen del Discussn.
