Shock absorbers play a very important role in the daily exercise of automobiles. The springs in the shock absorbers are more important. Let's take a look at the importance of springs.
The hardware spring has the characteristics of extensible compression, which can absorb and release the bouncing generated when the vehicle passes through an uneven road surface, thereby reducing the bounce amplitude of the vehicle and keeping the wheel in contact with the road surface as much as possible. The energy generated during the elongation process is converted into heat by the work of the shock absorber.
The hardware spring adopts a design in which the thickness and density are inconsistent. The advantage is that when the pressure is not high, the undulation of the road surface can be absorbed by the portion with a lower elasticity coefficient to ensure comfortable ride. When the pressure is increased to a certain extent, the thicker portion is The hardware spring plays a role in supporting the vehicle body. The disadvantage of this spring is that the handling experience is not direct and the accuracy is poor.
The thickness and density of the linear spring from the top to the bottom are constant, and the elastic coefficient is a fixed value. This design of the spring can make the vehicle obtain a more stable and linear dynamic response, which is conducive to the driver to better control the vehicle, and is mostly used for performance-oriented modified vehicles and competitive vehicles. The disadvantage is of course that the comfort is affected.
In addition, some racing cars and modified cars will add a small, softer, small auxiliary spring on a hard linear spring. This combined spring will not only increase the comfort but also reduce the rebound force when the main spring is compressed and rebounded. To prevent the main spring from disengaging from the spring seat.
Short springs are shorter than original springs, and they are more robust and short springs are installed, which can effectively reduce the center of gravity of the car body, reduce the roll caused by cornering, make the cornering more stable and smooth, and improve the handling of corners of vehicles.
The damper setting of the original shock absorber is biased towards comfort, so the short spring and the original shock absorber are not very stable in cooperation. It cannot effectively suppress the rebound and compression of the short spring, and when it is bumpy on the road, it will There is an unpleasant feeling of jumping, and in the long run, the lifespan of shock absorbers will be greatly reduced, and there may be oil leakage.
Of course, these conditions are relatively speaking, the daily driving will not have such a serious damage, but also try not to drastic driving, after all, the original shock absorbers can not afford the high load pressure.
