Spring classification

According to the nature of the force, the spring can be divided into tensile spring, compression spring, torsion spring and bending spring, according to the shape can be divided into dish spring, ring spring, plate spring, spiral spring, truncated conical scroll spring and torsion bar spring, etc., according to the production process can be divided into cold spring and hot spring. Ordinary cylindrical spring is the most widely used because it is simple to manufacture, and can be made into various types according to the load condition, and has simple structure. Spring manufacturing materials generally should have a high elastic limit, fatigue limit, impact toughness and good heat treatment properties, commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloy, nickel alloy and rubber. The spring is manufactured by cold winding method and hot winding method. The diameter of the spring wire is less than 8 mm, and the cold winding method is generally used for those greater than 8 mm. Some springs are also forced or shot peening after being made, which can improve the bearing capacity of the spring.

1, the helical spring is a torsion spring, which is a spring that bears torsion deformation, and its working part is also tightly wound into a spiral. The torsion spring end structure is machined into various shapes of the torsion arm, rather than the hook.

2. The tensile spring is a helical spring that bears axial tension. When the load is not borne, there is generally no gap between the ring and the ring of the stretched spring.

3, compression spring is to withstand the pressure of the spiral spring, its material cross-section is mostly circular, but also useful rectangular and multi-strand steel coil, the spring is generally equal pitch, the shape of the compression spring is: Cylindrical, conical, convex and concave and a small number of non-circular, compression spring between the ring and the ring will have a certain gap, when the spring is subjected to external load shrinkage deformation, storage deformation energy.

4, the torsion spring uses the lever principle to twist or rotate the elastic material with soft and strong toughness, so that it has great mechanical energy.

5, progressive spring, this spring adopts the thickness, density inconsistent design, the advantage is that when the pressure is not large, it can absorb the ups and downs of the road through the part of the lower elastic coefficient, to ensure the comfort of riding, when the pressure increases to a certain extent, the thicker part of the spring plays the role of supporting the body, and the disadvantage of this spring is that the control feeling is not direct, the precision is poor.

6, linear spring, linear spring from top to bottom thickness, density unchanged, elastic coefficient is a fixed value. The spring of this design can make the vehicle obtain a more stable and linear dynamic response, which is conducive to better control of the vehicle by the driver. It is mostly used for performance-oriented modified cars and competitive vehicles, and the harm is, of course, that the comfort is affected.

7, short spring short spring than the original spring is shorter, and more robust, installation of short spring, can effectively reduce the center of gravity of the body, reduce the roll generated during the corner, make the corner more stable, smooth, improve the vehicle bend handling. The damping setting of the original shock absorber is biased to comfort, so the short spring and the original shock absorber are not very stable in cooperation, it can not effectively inhibit the rebound and compression of the short spring, driving on the bumpy road, there will be a uncomfortable feeling of jumping, in the long run, the life of the shock absorber will be greatly reduced, and there may be oil leakage. Of course, these conditions are relatively speaking, daily driving will not have such serious damage, and try not to drive intensely, after all, the original shock absorber can not withstand high load pressure.
