vääntösraitteissa

Vääntösraiteissa, a Finnish term, translates to "torsion bar springs" in English. These are a type of spring used in vehicle suspension systems. Instead of a coiled spring, a torsion bar is a straight metal bar that twists along its longitudinal axis when force is applied. One end of the bar is typically anchored to the vehicle's frame, while the other end is connected to a suspension arm. As the suspension arm moves up and down due to road imperfections, it causes the torsion bar to twist. This twisting action provides the spring force, absorbing shocks and maintaining the vehicle's ride height.

Torsion bar suspension systems offer several advantages. They are relatively compact and can provide a low center of gravity for the vehicle, which can improve handling. They are also generally durable and require little maintenance. Historically, torsion bars were common in many types of vehicles, including early automobiles and some military vehicles. Today, they are still found in some trucks, SUVs, and performance cars. The design allows for easy adjustment of the vehicle's ride height by simply pre-loading the torsion bar to a specific degree.
