The car chassis system consists of four major systems: the transmission system, steering system, running system, and braking system. The transmission system includes the gearbox, clutch, universal transmission device, main reducer, differential, and half-shaft. The transmission system transmits the engine's power to the wheels, and without it, the car cannot operate normally. The suspension is a crucial component of the chassis, used to connect the wheels to the car body. Common independent suspensions in cars include MacPherson suspension, multi-link suspension, double-wishbone suspension, double transverse arm suspension, and double ball joint suspension.

When it comes to car chassis, the chassis system is the foundation of the entire vehicle. Having been a car enthusiast for many years, I can tell you it mainly consists of these major components: First is the drivetrain system, which includes the engine, transmission, drive shafts, etc., responsible for transmitting power to make the car move. Then there's the running gear system, primarily focusing on suspension and wheel components like shock absorbers and springs, which support the vehicle body for smooth driving. The steering system is also crucial, using the steering wheel to control direction, sometimes involving power assist devices. The braking system is all about the brakes, ensuring you can stop safely. Additionally, it includes the frame, which connects all parts like a skeleton. During regular maintenance, pay attention to periodic checks for suspension wear to avoid excessive bumps affecting handling. Oil leaks are common in the drivetrain section, so changing the oil frequently will make the chassis more durable.

I've driven quite a few cars, and the chassis system is like the skeleton and muscles of the human body, mainly consisting of several key components: the transmission section handles power transfer, from the engine to the gearbox; the running gear is responsible for support and cushioning, including the suspension system and tires; the steering section involves the steering wheel and linkage mechanisms, ensuring responsive direction control; the braking section comprises the brake components, guaranteeing safe deceleration. Overall, these parts must work in harmony. Once the suspension ages or produces abnormal noises, timely repairs are necessary to prevent safety hazards. During maintenance, avoiding driving too fast on rough roads can extend the chassis's lifespan.

As a new driver, I understand that the chassis system can be roughly divided into four parts: the transmission, which includes the engine and gearbox, gets the car moving; the running gear, consisting of the suspension and tires, ensures a smooth ride; the steering involves components connected to the steering wheel; and the braking system is related to the brakes. It's important to pay attention to these aspects while driving daily, as something like brake failure can be very dangerous.
