Application of springs in vehicles

The spring has the characteristics of stretch and compression. It can absorb and release the bouncing generated when the vehicle passes on uneven roads, reduce the amplitude of the bouncing of the vehicle, and keep the wheels in contact with the road as much as possible. The energy generated during the elongation process will be The work of the shock absorber is converted into heat energy and spread into the air.

The progressive spring adopts a design that is inconsistent in thickness and density. The advantage is that when the pressure is not large, the part with a lower elastic coefficient can absorb the fluctuations of the road surface to ensure riding comfort. When the pressure increases to a certain degree, the thicker part The spring plays the role of supporting the body, and the disadvantage of this spring is that the control feel is not direct and the accuracy is poor.

The thickness and density of the linear spring from top to bottom are unchanged, and the elastic coefficient is a fixed value. This design spring can make the vehicle obtain a more stable and linear dynamic response, which is beneficial to the driver to better control the vehicle and is mostly used for performance The downside of modified cars and competitive cars is that the comfort is affected.

In addition, some racing and modified cars will add a thinner and softer small auxiliary spring to the harder linear spring. This combined spring can not only increase comfort, but also reduce the rebound force when the main spring is compressed and rebounds. To prevent the main spring from leaving the spring seat.

The short spring is shorter and stronger than the original spring. The installation of the short spring can effectively reduce the center of gravity of the body, reduce the roll generated during cornering, make the cornering more stable and smooth, and improve the vehicle’s cornering maneuverability.

The damping setting of the original shock absorber is comfortable, 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. When driving on a bumpy road, it will There is an uncomfortable sense of jumping.In the long run, the life of the shock absorber will be greatly shortened, and there may be oil leakage.

Of course, the above conditions are relatively speaking, there will be no such serious damage in daily driving, and try not to drive violently, after all, the original shock absorber cannot withstand the pressure of high load.

Replacing short springs is the most affordable modification solution to reduce the height of the car. It is a good choice for those who have a small budget. Of course, you get what you pay for. The improvement of the control performance of the short spring is very limited, and there are many disadvantages. , So you must be clear about your purpose when buying, otherwise the installation will not achieve the expected effect at the time, causing unnecessary waste and sadness.
