Spring_Modification method of damping spring

The modification of the spring is mainly to improve the controllability, that is, to use a harder spring or a shorter spring. The spring controls many factors related to the control, and the change of the spring will cause a very complicated change in the control characteristics. In addition, it can improve the rolling suppression ability of the suspension and reduce the rolling of the body when cornering. The reduction of the height of the car can also reduce the center of gravity of the body, reducing the transfer of body weight when cornering, and improving the stability. Lowering can also take into account the aesthetic effect.
  The most important way to improve handling is to lower the center of gravity of the body, which can reduce the weight transfer of the body and the rolling of the body when cornering. The easiest way to reduce the body is to start with the spring. Using a short spring is the easiest and fastest way.
  The effect of spring hardness change:
  1. Increase the spring hardness of the front and rear suspension: the road performance becomes harder, and the tracking performance of the tire meridian road undulation will be worse, and the anti-roll ability will be improved
  2. Only increase the spring hardness of the front suspension: the front wheels become harder, and the anti-roll resistance of the front wheels increases, increasing understeer or reducing the tendency of oversteer
  3. Only increase the spring hardness of the rear suspension: the rideability of the rear wheel becomes harder, and the anti-roll resistance of the rear wheel increases, which increases the tendency of oversteer or reduces understeer
  4. Only reduce the spring hardness of the front and rear suspension: the road performance is soft, the tracking performance of the tire may become better when the road is undulating, and the anti-rolling ability will be worse
  5. Only reduce the spring hardness of the front suspension: the front wheel has a soft road and the front wheel anti-roll resistance is reduced, reducing understeer or increasing the tendency of oversteer
  6. ​​Only reduce the spring hardness of the rear suspension: the road performance of the rear wheel becomes soft, the anti-roll resistance of the rear wheel is reduced, and the tendency to oversteer or understeer is reduced
  7. Increase the hardness of the front anti-roll bar: The anti-roll resistance of the front wheels increases, increasing understeer or reducing the tendency of oversteer, which can reduce the change of the front suspension camber angle and make the tires closer to the road
   8. Increase the hardness of the rear anti-roll bar: The anti-roll resistance of the rear wheels increases, which increases the tendency of oversteer or understeer, which can reduce the change of the rear suspension camber and make the tires closer to the road
When refitting the spring, pay attention. Many people will only change the spring without changing the shock absorber. This modification method can easily deteriorate the control, because the damping of the original shock absorber cannot withstand the hardness of the modified spring, so when the spring expands and contracts When it is working, the original shock absorber cannot restrain the movement of the spring in such a short period of time. This will cause the vehicle to bounce more than ever. Not only is the modification effect of the spring difficult to play, but it will also shorten the life of the original shock absorber. .
