Coil Spring

. Coil Spring

A coil spring is shown in fig. 6.11. It is made from a special spring steel wire. This spring is generally circular in cross section and of suitable diameter to have the desired stiffness. The wire is wound in the shape of a col. The spring is formed at high temperature, cooled and proper heat treatment is given to it in order to have the characteristics of elasticity. When the wheel of the automobile experiences bump on the road side, the spring compresses to absorb the shock energy.  Coil springs are generally used in independent suspension system and other light duty vehicle.
