Vääntösauvaa
Vääntösauvaa, often translated as torsion bar, is a type of spring used in vehicle suspension systems. It is essentially a long, solid metal bar that, when one end is twisted, stores and releases energy. One end of the torsion bar is fixed to the vehicle's chassis, while the other end is connected to a suspension arm. As the wheel encounters a bump or dips into a hole, the suspension arm moves, causing the torsion bar to twist. This twisting action acts as a spring, absorbing the shock and returning the suspension arm to its original position.
Torsion bars offer several advantages. They are relatively simple in design and can be very durable. They
