The motive, gearbox, and chassis, commonly known as the three major parts of the car, are one of the most important elements related to the quality of the car. The structure of the car chassis is nothing more than this: springs, dampers, and some metal parts around it, nothing more, but in fact, Chassis components are even more important to car performance than tires that are in direct contact with the ground, so how important is a chassis?

It includes four major combined systems: driving system, braking system, transmission system and steering system. The reasonable layout and effective combination of these four major systems can give full play to the overall characteristics of the car chassis. Any unreasonable system link or hidden danger may be It affects the entire chassis system, but the engine is the core of the car's power, so it reflects the faults and defects most directly.

Driveline transmits power to wheels

The transmission device receives the power transmitted by the gearbox, and finally transmits to the transmission half shaft through the reducer, differential and other devices to drive the wheels to rotate. It contains the main original parts such as the transmission shaft, reducer, differential, clutch and transmission half shaft. , Can make the vehicle achieve acceleration and deceleration, reverse, differential, power interruption and other operations to ensure the stability and accuracy of vehicle power transmission, the transmission system is also divided into hydraulic transmission, hydraulic transmission and electric transmission, different transmission methods will Stability, precision and durability have a corresponding impact.

Chassis driving system

If the chassis is the basis of the vehicle's operating conditions, the driving system is the foundation of the chassis. The chassis driving system is the vehicle that receives the power of the driveline to ensure the reasonable operation of the vehicle. It cooperates with the braking system to ensure that the vehicle brakes and the steering system. To complete the control of the vehicle, it mainly includes the driving frame structure of the car's frame, sub-frame, suspension, tires, and beams. In addition, it is also the subsystem with the largest difference in the configuration and function of the car chassis.

The braking system brakes the vehicle

The main function of the braking system is to brake the vehicle. Its functions are mainly reflected in two aspects: running brake and parking brake. During the operation of the vehicle, the brake system brakes the vehicle or stabilizes the speed of the vehicle according to the driver's intention; The driving system and the driving system, these two systems allow the vehicle to run safely, but the vehicle needs to change direction and turn at any time, then the steering system in the chassis plays a big role at this time, the car The steering is composed of a steering machine and a steering machine, and then it is shown in the car as our common steering wheel. The car can walk and turn, but it is not safe to stop.

The steering system directly contacts the driver

The main function of the steering system is to control the car according to the driver’s intention. The steering system is a subsystem that directly contacts the driver and is an active system that needs to be operated by the driver. Another braking system in the chassis will come into play at this time. The braking system It is generally composed of a brake mechanism and a brake disc, and it also has a branch brake and a parking brake, that is, we see the brake pedal and hand brake on our car.
