Automotive leaf springs are also called blade springs.

Car shock springs are made of spring steel. Spring steel refers to the elasticity in the tempered state, and the elasticity of the steel specially used to manufacture springs and elastic elements depends on its ability to deform elastically, that is, within the specified range, the ability of elastic deformation makes it withstand a certain load, and it will not appear permanently after the load is removed; 090~120%, such as 65Mn two b alloy spring steel. Add one or several alloying elements to improve the mechanical properties of steel, hardenability and other properties to meet the performance of steel required for the manufacture of various springs. Generally, 60Si2Mn50CrV and other materials are used, and the process adopts blanking, drilling, curling ear quenching, tempering, shot peening, pre-pressing, painting, etc. Northern. CHENG An; Automotive suspension springs generally have carbon spring steel, manganese steel, silicon manganese steel, etc., carbon spring steel is less used in automobiles because of its low hardenability. Tempered brittle silicon-manganese steel is widely used in China. Spring shock absorbers are mainly used to suppress the shock and shock source when the spring absorbs the shock and rebounds.

The commonly used materials for the production of springs are high-quality carbon steel, alloy steel, non-ferrous metal alloys, stainless steel, etc., and the spring that uses the principle of material elastic deformation can produce large elastic deformation when subjected to force, and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring deformation disappears, returns to its original state, and the deformation energy is converted into; Spring steel refers to the elasticity caused by quenching and tempering state, the elasticity of steel specially used to manufacture springs and elastic elements depends on its ability to elastic deformation, that is, within the specified range, the ability of elastic deformation to withstand a certain load, after removing the load, spring steel without permanent deformation should have excellent performance; 1 carbon spring steel 2 alloy spring steel 1 carbon spring steel mostly use 65#, 70# 65Mn82B72A72B steel wire, which has the characteristics of low plasticity, strong elasticity and strong stress resistance.
