1. Reversing springs are springs that withstand reversals, and parts of its work are also spiraled. Reversing the end of the spring is a twisting arm in all shapes, not a hook. Twisting springs leverage the principle of great mechanical power by distorting or rotating material with soft, more resilient and flexible materials. 2. The stretch spring is a spiral spring that withstands axle pull. When the load is not carried, there is generally no gap between the circle that stretches the spring and the circle. 3. Compressed springs are spiral springs that withstand axle pressure and use materials with many contours and rectangular and multiple steel rolls, which are typically equidistant. Compressed springs are shaped such as cylinders, cones, cones, cascades and ingots and a small number of non-circles. There is a gap between the cones and circles of the compressed springs, which shrink when exposed to the outer charge, and store deformation. 4. Progressive springs, which are designed to be coarse and incoherent, have the advantage of absorbing the ups and downs of the road through lower elasticity coefficients when the pressure is low, ensuring comfort, and providing support for the body when the pressure increases to a certain degree in the thicker springs, which have the disadvantage of being less direct and less accurate. 5. Linear springs, which are thick and trimmed from top to bottom, with a constant elasticity factor. This design spring provides vehicles with a more stable and linear dynamic response that allows drivers to exercise better control over vehicles, many of which are modified for performance orientation and competitive vehicles, to the extent that comfort is affected. Six, short spring short springs are shorter than the original spring, and even more so
