Abstract
A leaf spring structure is designed as a single piece to be able to change the spring rates of leaf springs under a load independently from the manufacturing material. The operating mechanism of the leaf spring allows for increasing the spring rates by deactivating the short spring, which remains between the point A and the point B, as a result of the interaction between the short spring and the long spring after a certain amount of vertical displacement in the leaf spring.
