Detailed explanation of automobile chassis structure: The automobile chassis carries the engine and other key components, constitutes the overall framework of the automobile, and converts the power of the engine into motion, ensuring smooth driving of the automobile. It mainly consists of four systems: transmission system, driving system, steering system, and braking system. Next, we will introduce these systems one by one through diagrams.
The transmission system includes components such as clutch, gearbox, universal joint, final drive, differential, and half shaft. Its main functions are to regulate speed, reverse, interrupt power transmission, and adjust the speed difference between wheels, ensuring that the car can travel efficiently and stably under various driving conditions.
The driving system consists of a frame, axles, wheels, and suspension. It is responsible for receiving power from the transmission system, generating forward force through the interaction between the driving wheels and the road surface, while bearing all the weight of the car and ground reaction force. In addition, the driving system can also alleviate the impact caused by uneven road surfaces, reduce vibrations during driving, and ensure passenger comfort.
The steering system mainly consists of components such as the steering wheel, steering shaft, and steering column. Its function is to respond to the driver's steering operation, adjust or maintain the direction of the car's travel according to demand, thereby reducing the driver's handling burden.
The braking system includes multiple subsystems such as service braking, parking braking, emergency braking, and auxiliary braking. Its main responsibility is to slow down or stop the moving car according to the driver's instructions, while ensuring stable parking of the car in various road conditions (including slopes), and maintaining a stable speed when driving downhill.
