Leaf springs

   Leaf spring is simple form of spring commonly used for the suspension in wheeled vehicles. A leaf spring can either be attached directly to the frame at both ends or attached directly at one end, usually the front, with the other end attached through a shackle, a short swinging arm. The shackle takes up the tendency of the leaf spring to elongate when compressed and thus makes for softer springiness.Originally called a laminated or carriage spring, and sometimes referred to as a semi-elliptical spring or cart spring.
