In motor vehicles, leaf springs are most generally used in the rear suspension hardware. Leaf springs are made by the curving of flat steel bands. It is formed with the tying of a couple of thin leafs with short ones and then the longer ones put on top of one another. With this tying method, it does not break and is forced to be flexible. Every curve of the leaf is called a bend and this bend intensifies from the longer leaf to the shorter leaf. With the curving of the edge of the longest spring a spring eye is formed.
Through this part the spring is hung with a screw. Rubber rings are placed between the screw and its niche within the hanger. Thus, the metal does not touch the other metal. These rubber rings absorb the vibrations and they prevent their transmission into the chassis. Meanwhile, while the spring is bent, the eye of the spring can bend forward and backward.
