【 Modified school 】 Suspension modification is very deep? Let's briefly understand the basics

What is the suspension system?

Automotive suspension system refers to a connecting structural system between the body, frame and wheels. Includes bushing, connecting rod, suspension swing arm, anti-tilt rod, shock absorber, suspension spring and other components.

Common suspension is divided into non-independent suspension and independent suspension, independent suspension mainstream including McPherson suspension, double fork arm suspension, multi-link suspension and so on.

The benefits of retrofitting the suspension system?

Retrofitting the suspension system can improve the car's handling and stability;

The suspension geometry can be corrected after the chassis is raised or lowered;

By changing the suspension parameter setting, the vehicle's handling characteristics can be changed to adapt to different use needs.

The shock absorber part has been explained separately, interested friends can look at the past content, this article focuses on the swing arm, tie rod, anti-tilt rod and bushing.

One, swing arms

Suspension swing arm action

The suspension swing arm is a key component that connects the body, springs, shock absorbers and wheels. It can change the geometry according to the vehicle driving state and road conditions, ensuring that the tire maintains good contact with the ground.

Swing arm modification

Modified swing arm is generally out of strengthening or to obtain more adjustment space, so the general choice of adjustable products, through the length of the swing arm adjustment, you can change the Angle of the vehicle.

Two, pull rod

Suspension tie rod action

Similar to swing arms, suspension tie rods are commonly used in multi-link rear suspension to connect the body to the wheels.

Modification of the tie rod

Modified tie rod generally choose adjustable style, by adjusting the length of the tie rod, you can change the vehicle inclination and beam Angle and other parameters.

Three, anti-tilt rod

The role of the anti-tilt rod

An anti-roll bar (stabilizer bar) is an elastic connecting rod that connects the left and right suspension.

The anti-roll bar can balance the left and right suspension by transferring the force on one side of the suspension, reducing the roll of the vehicle during the turning process.

Modification of the anti-tilt rod

Modification of the anti-tilt rod, generally by replacing a thicker diameter of the product, improve the elasticity of the anti-tilt rod, reduce vehicle roll, improve the handling limit, but too thick anti-tilt rod may cause the left and right suspension work interference, affecting comfort.

Four, bushing

The role of the bushing

The bushing is used to connect the rod of the suspension swing arm and is generally made of rubber.

The bushing can reduce the wear and vibration between the components, play a buffer effect, improve the driving quality and ride comfort.

Modification of bushing

Modified bushings are generally made of harder materials than the original factory to improve control and enhance suspension responsiveness, generally made of silicone material, if the car will use metal bushings hard connection, but hard bushings will affect comfort.

The modification of suspension system involves vehicle control and driving stability, which has a very advanced knowledge; The suspension system is usually modified in the hope of adjusting the chassis Settings more suitable for their driving style. Compared with the power upgrade, the suspension modification needs more experience accumulation, but the effect can also reflect the speed of the vehicle through the corner, the street has been circulating the corner fast is really fast, in fact, it is to rely on the suspension adjustment.
