Independent suspension

The independent suspension is that the wheels on each side are individually suspended on the frame or under the body through an elastic suspension. Its advantages are: lighter weight, less impact on the car body, and improved ground adhesion of the wheel; soft spring with small rigidity can be used to improve the comfort of the car; the position of the engine can be reduced and the center of gravity of the car can be reduced. Improve the driving stability of the car; the left and right wheels beat independently, and they are irrelevant, which can reduce the tilt and vibration of the car body. However, the independent suspension has the disadvantages of complicated structure, high cost, and inconvenient maintenance. Most modern cars use stand-alone suspensions. According to their different structures, independent suspensions can be divided into horizontal arms, vertical arms, multi-links, candlesticks, and McPherson-type suspensions.
