What is torsion bar spring

Torsion bar spring is a kind of rod spring with one end fixed and the other end connected with working parts. Its main function is to absorb vibration energy by torsion force
Application: the torsion bar spring is used for automobile frame and wheel, one end of which is fixed on the frame and the other end is connected with the wheel. When the wheel jumps up and down, the torsion bar produces torsion deformation and absorbs the vibration energy by torsional elastic force; the torsion bar spring is used as the damping component of automobile frame and wheel, with simple structure and small structure, which is suitable for small cars.
