Automobile chassis parts are divided into:

1. Transmission system: clutch, transmission, final reducer, half shaft, universal joint, transmission shaft.

2. Driving system: frame, balance bar, axle, wheel, ingot beam, shock absorber, horn, support arm, three-way catalysis.

3. Steering system: steering shaft, steering tie rod.

4. Braking system: brake disc, brake cylinder, brake pad.

The structure of each part of the car chassis

1. Transmission system:

(1) Clutch: It is to ensure that the car starts smoothly, shifts smoothly, prevents overload during the transmission process, and prevents the impact of torsional vibration.

(2) Transmission: It is used to coordinate the speed of the engine and the speed of the wheels, so as to release the best performance of the engine.

(3) The main reducer: It is a component that reduces the speed and increases the torque during the transmission process. The speed of its transmission is reduced to obtain a relatively high output torque, thereby obtaining a greater driving force.

(4) Half shaft: It is also the drive shaft, the shaft that transmits the power.

(5) Universal joint: It is a device that controls the steering of the car and is a vector transmission power device.

(6) Transmission shaft: It is installed between the transmission and the rear axle, which means that the torque and rotational power brought by the transmission are transmitted to the rear axle.



2. Driving system:

(1) Frame: It is a frame used to carry various parts of the chassis, and it is also a protective frame to withstand external pressure.

(2) Balance bar: It is used to improve the handling performance of the car, especially in the process of turning.

(3) Axle: It is used to transmit the forces in all directions brought by the frame and the wheels.

(4) Wheels: Bearing and rolling are his final choices.

(5) Yuanbao beam: used to carry the engine and gearbox, but also to strengthen the strength of the body.

(6) Shock absorber: its function is to reduce the vibration of the frame and the body, so that the vehicle can be driven smoothly, safely and comfortably.

(7) Claw: It plays the role of link steering, which links shock absorption and lower arm.

(8) Support arm: It acts as a fixed link and is used for the link between the frame and the horn.

(9) Three-way catalysis: It is a channel for removing exhaust gas. Turn it into a harmless carbon dioxide, water, nitrogen catalyst.

3. Steering system:

(1) Steering shaft: increase the turning force given by the steering wheel, so as to smoothly change the direction of the force transmission.

(2) Steering tie rod: coordinate with the steering shaft to complete the corresponding steering work.

4. Braking system:

(1) Brake disc: It acts on the brake pads at the same time to make the vehicle brake, providing only a friction surface.

(2) Brake cylinder: providing power to push the brake pads to make them rub against the brake discs for braking, which is the function of giving braking courage.

(3) Brake pads: friction with the brake disc achieves braking effect.

The above is the introduction of the car chassis parts, let's take a look at the car chassis reinforcement parts.



What are the reinforcement parts of the car chassis:

1. The front wheel sway arm balance lever (the original car's necessary accessories are also called front anti-roll bars), designed and installed on the separate connection between the front axle and the front wheel, and its main function is to control the front wheel. Inside and outside inclination, see Small roll.

2. The steering toe-in balance lever (a necessary accessory for the original car) is designed to be installed on the lower swing arms of the front wheel on both sides to control the overall symmetry of the front wheel in the direction. The main function is to be responsible for the forward inclination of the front wheel and to maintain the tracking ability of the steering wheel.

3. The front wheel shock absorber tower top balance rod (commonly known as Hong Kong and Macau: top bar, optional) is designed to be installed on the top of the front shock tower tower. Its main function is to enhance the rigidity of the cabin and the front body and offset centrifugal force. The frame deformation caused by lateral torsion (serious deformation can cause the tower top to tear), improve the cornering ability of the vehicle, increase the cornering speed, and reduce the roll angle of the body caused by centrifugal force.

4. The front bottom beam balance rod (commonly known as: front bottom bar, optional) is designed and installed at the connection part between the front axle and the front of the frame chassis. The main function is to enhance the connection strength between the front bottom beam (front axle) and the chassis. The main function of reducing the displacement and deformation of the front axle caused by centrifugal force and body torsion is also to improve the cornering performance.

5. The balance rod on the top of the rear shock tower (commonly known as: rear roof, optional) is designed and installed on the top of the rear shock tower. Its main function is to enhance the strength of the trunk and reduce the size of the rear The lateral twist caused by centrifugal force at the part reduces the roll degree of the rear of the vehicle when cornering, and improves the cornering performance of the vehicle.

6. The rear axle suspension reinforced balance rod (commonly known as: rear bottom bar, optional) is designed and installed at the connection position between the rear axle and the rear of the frame chassis. The main function is to strengthen the connection strength of the rear axle and the frame.

7. Frame (body), chassis reinforced balance rod (component).

How Chassis Reinforcement Works In the

daily environment, our vehicle is subjected to external forces on the road while driving, which will cause the body to twist. At this time, the lower the body rigidity, the greater the body twist will be. The low rigidity of the body will also cause the body to twist, affecting the contact surface between the tire and the ground, resulting in a decrease in the turning performance and handling performance of the vehicle.

The advantage of installing the chassis reinforcement is that it can pull the various parts of the chassis, thereby strengthening the rigidity of the body and suppressing the distortion of the body. At this time, the vehicle handling will feel more sensitive, the reinforced body will also absorb the impact from the ground, improve the comfort, the vehicle will be more stable, and the loose feeling caused by the aging of the body will also be reduced. Play to the extreme, so that the body can effectively disperse the torque.
