Torsionsstabaufhängung

Torsionsstabaufhängung refers to a type of independent suspension system used in vehicles. In this system, a torsion bar, which is a long metal rod, is used as the spring element. One end of the torsion bar is attached to the vehicle's chassis, while the other end is connected to the suspension arm that controls the wheel. When the wheel encounters a bump or dip in the road, the suspension arm pivots, causing the torsion bar to twist. This twisting action absorbs the shock and allows the wheel to move up and down while keeping the vehicle body relatively stable.

Torsion bars can be mounted longitudinally, running from front to back along the vehicle's frame, or transversely, running across the vehicle. Longitudinal torsion bars are more common in rear-wheel-drive vehicles, while transverse setups are often found in front suspensions. The stiffness of the torsion bar can be adjusted, typically by changing its diameter or material, allowing for fine-tuning of the suspension's ride and handling characteristics.

This type of suspension offers several advantages, including a low profile, which can be beneficial for packaging within the vehicle, and a relatively simple design. It also allows for independent wheel movement, meaning that the movement of one wheel does not directly affect the other, contributing to improved ride comfort and stability. Historically, torsion bar suspension was widely used in various passenger cars and military vehicles.
