The torsion bar uses the reaction force generated by the force of the rod to keep the left and right sides of the car at a similar height to avoid tilting. From small cars to heavy trucks, the front suspension is mostly equipped with stabilizer bars. Stabilizer bars come in a variety of forms, but are basically torsion bar shapes, due to the need to avoid other components around them.
The anti-roll resistance provided by the torsion bar and the spring is complementary, and the anti-roll resistance occurs in pairs, that is to say, the anti-roll resistance of the front is accompanied by the anti-roll resistance of the rear, but due to the body weight ratio and The relationship between other external forces will make the front and rear anti-roll resistance unbalanced, which will directly affect the transfer of body weight and the balance of handling.
