Product Description
he automobile leaf spring is the most traditional elastic element in the automobile suspension system. It is widely used due to its good reliability, simple structure, short manufacturing process, low cost and greatly simplified structure. Automobile leaf springs are generally composed of several pieces of alloy spring steel of unequal length to form a group of spring beams with similar strength. In the suspension system, in addition to playing a buffering role, when it is placed in the longitudinal direction of the car and one end is connected to the frame with a fixed hinge, it can be responsible for transmitting all forces and torques in all directions, as well as determining the trajectory of wheel movement, and playing a guiding role. Therefore, there is no need to set up other guiding mechanisms. In addition, the automobile leaf spring is composed of multiple pieces. When deformed under load, each piece has relative sliding and friction, which produces a certain resistance and promotes the vibration attenuation of the car body. Therefore, this structure can be used without shock absorbers. However, the energy stored per unit weight of the leaf spring is the lowest, so the utilization rate of some materials is the worst. Generally, the multi-leaf spring ε=60%, and the small leaf spring ε=75%~85%. It consumes a lot of alloy steel, and its weight accounts for 8~9% of the car's own weight.
