What does the balance bar do, what does the car balance bar do?

The "scientific name" of "top bar" is called the anti-roll balance bar, which is the most basic modification in car modification.

The "top bar" is mainly installed on the front suspension of the sedan, and for many people the anti-roll bar is just an inconspicuous bar, but its improvement effect on handling can be said to be the most obvious effect of all modification projects. We know that when a car is cornering, it will roll due to the action of centrifugal force, resulting in the suspension stretching and compression of the bent inner and outer wheels. However, the softer suspension will cause the car to become more sideways when cornering.

After the installation of the "top bar", although we have not changed the softness and hardness of the sedan suspension, but after the two front suspensions are connected together, the rigidity of the front part of the sedan is enhanced, and the deformation of the two front suspensions becomes smaller during the cornering process, and the first force generated by the twisting and stretching of the "top bar" shaft is used to inhibit the body roll.

According to the riders who installed the "top bar", after installing the "top bar", they will feel that the body is "tight" in the car, and when changing the line or cornering urgently, it seems that there is an invisible hand suppressing the roll of the body, making the steering more accurate and increasing the driver's confidence. In the words of a rider, 80 (speed) can't pass the corner, after adding "top", you can go over 90!

It plays a balancing role, and the unbalanced car will deviate, which is connected to the two front wheels.

**What is the role of the most common balance bar in training?

Front Wheel Lower Swing Arm Balance Tie Rod (a necessary accessory for the original car) - designed and installed in the front axle and the front wheel separately connected, the main role is to control the front wheel of the inside and outside roll angle;

2。Toe-in balance rod (essential part of the original car) – Designed to be mounted on the lower swing arms of the front wheels on both sides, it controls the overall symmetry of the directional front wheels. The main function is to be responsible for the forward inclination angle of the front wheel and maintain the tracking ability of the steering wheel;

3。Front wheel shock tower top balance rod (commonly known as Hong Kong and Macau: top bar.

Optional) — Designed to be mounted on the top of the front shock tower. The main function is to enhance the rigidity of the engine room and the front body, offset the frame deformation caused by centrifugal lateral torque (the deformation can cause the top of the tower to tear in severe cases), improve the cornering ability of the vehicle, increase the cornering speed, and reduce the roll angle of the body caused by centrifugal force;

4。Front bottom beam balance rod (commonly known as: front bottom bar.

Optional) — designed to be mounted on the front axle at the junction with the front of the frame chassis. The main function is to enhance the connection strength of the front bottom cross member (front axle) and the chassis, reduce the displacement deformation of the front axle caused by centrifugal force and body twisting, and its main role is also to improve cornering performance;

5。Rear wheel suspension tower top balance rod (commonly known as: rear top bar.

Option) — Designed to be mounted on the top of the rear shock tower. The main function is to enhance the strength of the trunk, reduce the lateral twist caused by centrifugal force at the rear of the compartment, reduce the roll of the rear of the car when cornering, and improve the cornering performance of the vehicle;

6。Rear axle suspension reinforced balance rod (commonly known as: rear bottom bar. Optional) — designed to be mounted on the rear axle at the rear of the frame chassis. The main function is to strengthen the connection strength between the rear axle and the frame;

7。Frame (body) chassis reinforced balance rod (assembly) — Designed to be installed in the middle of the frame chassis, the main function is to enhance the overall rigidity of the frame chassis.
