Torsion beam rear suspension can adjust camber. When the car turns, the center of gravity is outside the car, which is very important for the grip outside the car. If adjusted to the outer contour, the outer tire will only make a 90-degree angle with the ground when the car rolls. After all, the inner wheel has weak grip. The camber angle of suspension can be adjusted after torsion: according to different adjustment forms, it can be divided into passive suspension and active suspension. According to the different steering mechanisms, it can be divided into independent suspension and dependent suspension. Independent suspension can also be divided into fork arm type, trailing arm type, multi-link type, candle type and McPherson type. Torsion beam suspension can be divided into torsion beam dependent suspension and torsion beam semi-independent suspension; The advantage of independent suspension is that the wheels of independent suspension are basically independent, and the vibration fluctuation of one wheel has no influence on the other wheel, while the torsion beam is a suspension that connects the upper and lower wheels with a cross beam, and the jumping of one wheel will definitely affect the other wheel, so the ride comfort and handling feeling of independent suspension are better than before.
