The valve spring acts in the suspension system to support the body and absorb the impact of uneven road conditions and other forces on the tires. Other forces here include acceleration, deceleration, braking, turning and other forces applied to the spring. More importantly, in the process of absorbing vibration, it is necessary to ensure that the wheels do not leave the road, to ensure the tracking of the car, to ensure sufficient grip and good handling. This determines the position of the spring in the car!
The main function of the spring is to maintain the comfort of the car and keep the tires in full contact with the ground. Using the wrong spring will have a negative impact on the driving quality and handling. Just imagine if the spring is completely stiff, the suspension system will not work. When the car jumps up on uneven roads, the tires will also completely leave the ground. If this happens when accelerating, braking or turning, the car will lose track. If the spring is very soft, it is easy to "sit on the bottom", that is, the suspension travel will be exhausted. Car interior springs, car seat springs, if the bottom of the car seat occurs when cornering, it can be regarded as the spring's elastic coefficient becomes infinite (there is no compressed space), and the body will produce immediate weight transfer, resulting in tracking Of loss. If this car has a long suspension stroke, it may be possible to avoid the "sit bottom" situation, but the relative body will also become very tall, and a very tall body means a very high center of gravity of the body. The high or low has a decisive influence on the handling performance, so too soft shock absorbers will cause handling obstacles. If the road is flat, then we don't need springs and suspension systems. If the road is rough, a softer spring is needed to ensure that the tire is in contact with the road. At the same time, the travel of the spring must be increased. The choice of spring hardness is determined by the ruggedness of the road surface. The more rugged the spring, the softer the spring, but how soft it is is a key issue. Usually this requires the accumulation of experience and is also important for spring companies, various car manufacturers and various teams. Subject. Spring manufacturer
