Spring classification

According to the nature of the force, the spring can be divided into tensile springs, compression springs, torsion springs and bending springs, according to the shape can be divided into disc springs, ring springs, leaf springs, coil springs, truncated cone scroll spring and torsion bar springs , According to the production process can be divided into cold coil spring and hot coil spring. Ordinary cylindrical spring as the manufacture of simple, and can be made according to load conditions of various types, simple structure, so the most widely used. materials in general should have a high elastic limit, fatigue limit, impact toughness and good heat treatment properties, commonly used carbon spring steel, alloy spring steel, stainless steel spring steel and copper alloy, nickel alloy and rubber Wait. Spring manufacturing methods are cold roll and hot coil method. Spring wire diameter of less than 8 mm of the general use of cold roll method, greater than 8 mm with the hot volume method. Some of the springs in the finished but also for strong pressure or shot peening, can improve the spring carrying capacity.

1, the coil spring that is torsion spring, is to withstand the torsion deformation of the spring, it is also part of the work around the spiral wound. Torsion spring end structure is processed into a variety of shapes of the arm, not the hook ring.

2, the tensile spring is to withstand the axial tension of the coil spring. In the absence of load, the tension spring between the ring and the circle are generally tight and no gap.

3, the compression spring is to withstand the pressure of the coil spring, which is mostly circular cross-section of the material, but also useful for rectangular and multi-strand steel Ying rolling, the spring is generally equal pitch, compression spring shape: cylindrical , Conical, convex and concave in the concave and a small amount of non-circular, etc. and the circle between the circle will have a certain gap, when subjected to external load when the spring contraction deformation, storage deformation energy.

4, torsion spring lever principle, through the soft material, toughness of the larger elastic material twist or rotation, so that it has great mechanical energy.

5, progressive spring, the spring using the thickness, density inconsistent design, the advantage is not much pressure can be adopted by the lower part of the coefficient of elasticity to absorb the ups and downs of the road to ensure ride comfort, when the pressure increases to To a certain extent after the thick part of the spring to play the role of supporting the body, and the disadvantage of this spring is not directly feel the control, the accuracy is poor.

6, linear spring, linear spring from top to bottom of the thickness, density unchanged, the elastic coefficient is fixed. This design of the spring can make the vehicle to obtain a more stable and linear dynamic response is conducive to better control of the vehicle drivers, for performance-oriented modified cars and competitive vehicles, the disadvantages of course, comfort is affected.

7, short spring short spring compared to the original spring to be shorter, and more sturdy, the installation of short spring, can effectively reduce the body center of gravity, reduce cornering when cornering, cornering more stable, smooth, improve vehicle bend Road handling. The original shock absorber damping set bias comfortable, so the short spring and the original shock absorber in the match is not very stable, it can not effectively suppress the short spring springback and compression, driving in the bumpy road, will There is a sense of discomfort jump over time, the life of the shock absorber will be greatly reduced, and there may be oil spills. Of course, these conditions are relatively speaking, the daily driving, then there will not be such a serious damage, and try not to drive, after all, the original shock absorber can not afford high-load pressure.
