The middle of the leaf spring is fixed on the axle by U-shaped bolts, and the rolling ears at both ends are hinged on the bracket of the frame with pins. In this way, the axle is connected to the vehicle body through leaf springs, which play the role of buffering, vibration reduction and force transmission. Each leaf of a multi-leaf spring is an inverted triangle, with the top leaf being the longest and the bottom being the shortest. The number of steel plates is related to the weight of the supporting car and the shock absorption effect. The thicker and shorter the steel plate, the greater the stiffness of the spring. However, when the leaf springs bend, they slide and rub against each other, creating noise. Friction can also cause the springs to deform, resulting in a rough ride. Therefore, on cars with low load-carrying capacity, a few leaf springs appear to eliminate the defects of multiple leaf springs. Some few leaf springs only use a single leaf spring. Compared with multi-leaf springs, it not only reduces noise and friction, but also saves materials, reduces weight, facilitates layout, lowers the height of the vehicle, and has good ride comfort. The cross-section of the steel plate of the few-leaf leaf spring changes greatly, and the cross-section gradually changes from the middle to both ends, so the rolling process is more complicated.
