O princípio de trabalho dos acessórios do chassi inclui principalmente o princípio de trabalho de quatro principais subsistemas: sistema de transmissão, sistema em execução, sistema de direção e sistema de frenagem .
Sistema de transmissão
The main function of the transmission system is to transmit the power of the engine to the wheels. The manual transmission changes the meshing position of the gears by manually turning the gear lever, thereby changing the transmission ratio and achieving speed change and gear shifting. The clutch is located between the engine and the gearbox. By stepping on or releasing the clutch pedal, A potência do motor é cortada ou transmitida para garantir o início e a suavidade do carro ao mudar de engrenagem .
Sistema em execução
The running system includes the front axle and the rear axle, which support the vehicle body and transmit driving force, braking force and steering force. The front axle is usually located at the front of the vehicle, connecting the two front wheels, and may integrate a steering mechanism to achieve flexible steering of the vehicle. The front axle design of modern cars often adopts complex suspension systems, such as McPherson, double wishbone or multi-link, to improve ride comfort and handling stability. The rear axle is located at the rear of the vehicle, connecting the two rear wheels. It is mainly responsible for transmitting engine power and braking force. The rear axle of some models also has a differential function to adapt to the difference in the speed of the inner and outer wheels when the vehicle Turns .
Sistema de direção
The main function of the steering system is to control the direction of the vehicle. The recirculating ball steering gear realizes the steering of the vehicle through the gear rack transmission. The driver turns the steering wheel to drive the ball in the recirculating ball steering gear to roll, and then the wheels are turned through the gear rack transmission mechanism.
Sistema de frenagem
The main function of the braking system is to slow down or stop the vehicle. The braking system usually includes brake pads and brake discs, which generate braking force through friction to slow down or stop the vehicle. Modern cars are also often equipped with electronic braking systems (such as ABS) to improve braking effect and safety.
