Automotive leaf spring structure, in full use of materials on the basis of its structure close to the stress beam. The form of leaf spring close to the stress beam can be divided into two categories, namely, multi-plate leaf spring and less sheet leaf spring.
Multi-leaf spring width is narrow at both ends of the middle width, regardless of the middle or both ends are equal, this leaf spring steel sheet by the composition of these different lengths of steel, the width is the same, this leaf spring Is a more traditional type. The current leaf spring is used in large passenger cars or trucks. A small piece of spring its width regardless of the middle or both ends are equal, the thickness is thin on both ends of the middle. The current leaf spring is used in light vehicles.
Why is the leaf spring hard? Automotive leaf spring design using the traditional shock-absorbing suspension structure, leaf springs can support its body, and it can also absorb the impact of the role, these are generally from the rugged road surface and other aspects of the tire imposed. Leaf spring to eliminate vibration, but also must pay attention to the road and tire to maintain sustained contact. If the leaf spring hardness is not strong, it will not play in the car suspension, and affect the reasonable control of the car. The role of leaf spring in the car is missing, then the infinite magnification of the elastic coefficient will make the body quality transfer occurs, and the body will become very high, the car's center of gravity will be high, thus affecting the overall control of the car.
