(1) Progressive spring
This kind of spring is usually designed with inconsistent thickness and density. The advantage is that when the pressure is not large, it can absorb the ups and downs of the road surface through the part with the lower elastic coefficient, thereby ensuring the comfort of riding. When the pressure increases to a certain level, the thicker springs play a role in supporting the body, but its disadvantage is that the control experience is not direct and the accuracy is poor.
(2) Linear spring
The elastic coefficient of the linear spring is a fixed value, it can make the vehicle obtain a more stable and linear dynamic response, and can better control the vehicle, but the comfort will be affected, so it is mostly used for performance-oriented modified cars and competitive vehicles.
(3) Short spring
It can effectively lower the center of gravity of the vehicle body, thereby reducing the roll generated when the vehicle is cornering, making the vehicle cornering more stable and smooth, improving the maneuverability of the vehicle cornering, and reducing the vehicle height. However, it is not very stable in cooperation with the original shock absorber, and cannot suppress rebound and compression very well. When the vehicle is driving on bumpy roads, there is an uncomfortable jumping feeling. Therefore, the improvement of the handling performance of the short spring is very limited, and there are also disadvantages, we should be cautious.
