Leaf spring

It is made up of multiple sheets of steel with unequal lengths and unequal curvatures. After the installation, both ends naturally bend upward. When the impact force of the road surface on the wheel comes, the steel plate will be deformed to play a role of buffering and damping, and it will also have the function of guiding the force transmission when it is arranged longitudinally. Most of the non-independent suspension uses leaf springs as elastic elements, which can eliminate the guide device and shock absorber, and has a simple structure.
