A car’s suspension system is very complex, with the parts inextricably linked to one another. Irrespective of a car’s condition and size, just the 4 tires touch the ground, and in addition, they undertake the weight of the car itself as well as the people and things the car carries. A few assume a vehicle (front engine, front-wheel drive) has a total weight of 1, 000 kg. Whenever static, the front and rear tire on each side bear 300 kilograms and 200 kg correspondingly, while the dumbbells have some subtle changes when the car gets started out. The dynamic inertia will cause a weight copy to the vehicle, no subject it is speeding finished, slowing down or steerage, thus resulting in swift bear load growth of some individual tires. Pertaining to example, if there’s an emergency brake on the ground, the weight that is formerly borne by the rear tires would instantly transfer to the front tires. That is to say, both past tires, which only keep 600 kg altogether, will now undertake perhaps more than 800 kg. Even greater, if the car substantially turns right when demoting at a high rate while the driver abruptly loses the throttle, the weight load of the right rear tire would become zero because the auto is now up in the air! At the moment, the weight load of the departed front tire would reach as much as 800 kg, while the departed rear tire and the right front tire will take 80 kg and 120 kg respectively. This kind of phenomenon of severe disproportion would let the left side front tire slip due to heavy load, thus shedding the ability of steerage. With this situation, if the driver depresses the braking mechanism in a hurry, extra fat would transfer to front side. As a consequence, the left rear wheel has not enough downforce because of little weight load, so the frictional force is not enough to cope with the left lateral force made by the right flex, thus creating a still left traverse.
The above is a simplified example, however, the basic principle is perhaps clear, and we can come to a realization that if we could reduce the weighted copy in a movement, the limit of slip can then be increased, thus resulting in a considerable improvement in the overall handling. And today I’d like to introduce several techniques to reduce the weighted copy.
The first way is to minimize the car’s weight. As soon as the gross weight is less, the transferred weight is therefore reduced. That is to say, the dumbbells of the four tires under the same condition is much less, so the limit will certainly increase. Please remember to reduce the useless products in the car, especially in the trunk, because they will follow the car’s dynamic inertia to transfer, thus affecting the stability.
The 2nd way is to lower the vehicle’s center of gravity, because the lower the center of gravity is, the less the car ups and downs, meaning the less of weight transferred at the same time. The least difficult way to lower a car’s center of the law of gravity is to decrease the height of the vehicle. But do not delicately cut the original arises to achieve your goal as this may cause some side effects.
The third way is to exercise a car’s ability of anti-heeling (roll stiffness), which requires strengthening the body and suspension system to control sway amplitude of the car. The most frequent way of this kind of customization is to install hi-strength springs and shock absorbers and equip the car with front and back tower bars, as well as anti-roll bars.
