American Trailer Leaf Spring Assy

American Trailer Leaf Spring Assy

Automotive leaf springs are also called blade springs.

Automotive spring steel plate is commonly known as bow plate, the material is 65Mn sixty-five manganese spring steel; Generally, 60Si2Mn50CrV and other materials are used, and the process adopts cutting, drilling, rolling ears, quenching, tempering, shot blasting, assembly, pre-pressing and coating. Automobile springs, also known as leaf springs, commonly known as steel plates in the northern region, are composed of several steel plates of different lengths and curvatures. After installation, both ends naturally bend upwards; The carbon in spring steel is usually 4047 degrees HRC after tempering in China, and it cannot be too high. Yes, the carbide drill bit that will affect the fatigue life should be fine, as long as the speed is low, it is factory processed; The spring steel plate of the general car adopts 65Mn65 manganese steel, and manganese steel is mainly used for impact extrusion. Carbon spring steels and alloy spring steels are also used for material wear and other harsh working conditions. The ordinary hardness of 65Mn is below HRC20, and the hardness after heat treatment can reach duHRC60; 60Si2Mn spring steel 60Si2Mn spring steel is made of cold stamping material, usually 60Si2Mn spring steel will have elasticity and hardenability on automobiles, suitable for all models; Spring steel refers to the elasticity in the tempered state, and the elasticity of steel specially used to manufacture springs and elastic elements depends on its ability to elastically deform, that is, within the specified range, the ability of elastic deformation makes it withstand a certain load. After a long period of time; 4. For springs bearing static load and variable load with limited number of actions, spring steel such as 657060Si2MnA65Si2MnWA, 50CrVA and so on can be selected. The material requires corrosion resistance, magnetic resistance and high electrical conductivity.
