How Shock Absorbers Work

Body weight transfer

The speed of body weight transfer when entering and exiting a corner will affect the balance of the handling. This effect will continue until the weight transfer is completed. The speed of body weight transfer is controlled by the shock absorber, changing the shock absorber in compression and the speed of the stretch stroke can change the speed of the body momentum transfer. The stiffer the shock absorber, the faster the weight transfer, and the faster the weight transfer, the faster the steering response of the body.

When turning the steering wheel when cornering, the tire will generate a slip angle (Slip Angle), which will generate a steering force, which acts on the Roll Center and the Center of Gravity, and then causes the body weight to shift and the body rolls. (Roll). At this time, the steering force of the outer wheel will increase with the increase of the slip angle and the transfer of the body weight. After reaching the maximum steering force and completing the weight transfer, the car will establish a Take a set. The shock controls the rate of weight transfer, and therefore also affects the rate at which the cornering position is established. Since steering response is very important to handling, we want to establish the cornering position as quickly as possible, but not too fast. There must be time for the driver to feel the establishment of the cornering position and feel the limit of tracking, if the weight Too fast transfer will make the driver too late to feel it, so setting a speed of body weight transfer so that the hot driver can feel the limit is approaching and reacting is an important issue when setting the vehicle suspension. We often say that teams will have different vehicle settings according to different drivers. For the suspension system settings, different drivers will feel different speed and reaction speed of steering response due to different driving skills and habits. Therefore, different suspension settings are required in order to obtain the full play of the driver.

First-hand principle

Turning the steering wheel once when entering a corner will generate a weight transfer change of the body, establishing a cornering posture in which the steering force and tire grip are balanced. The so-called cornering limit occurs when the steering force is equal to the grip of the tires. Someone will turn the steering wheel continuously after entering the corner, which is really a big mistake, because this will cause the body to corner in an unbalanced state, so the driver will not be able to drive the car to the limit, reducing the speed of cornering and There is a crisis out of control. When cornering, you should try to follow the so-called "one-handedness" principle. After determining the angle of the corner, turn the steering wheel into position at one time, so that the body can establish a balanced cornering posture as soon as possible. After exiting the corner, it is also the one-handed too much that allows the transferred body weight to return to the straight line. status. If you encounter a sudden situation in the corner, you must make a smooth and smooth correction to avoid abruptly intensifying the weight transfer that is already at the limit edge, making it uncontrollable and causing the body to lose control.
