What is the function of the automobile running system?

The function of the automobile running system: to bear the gravity and torque of various components of the automobile, transmit various forces and torques between the automobile and the ground, mitigate the impact of uneven ground, absorb vibration energy and attenuate automobile vibrations, ensuring smooth driving. The composition of the running system is as follows: Frame: The frame is the assembly base of the entire automobile, with most components and assemblies fixed through the frame. There are two different frame and body structures in automobiles, namely the non-load-bearing body structure with a frame and the load-bearing body structure without a frame. Axle: The axle is the crossbeam between the left and right wheels. According to their different functions, they are divided into drive axles, steering axles, steering drive axles, and support axles. The drive axle has been mentioned before, and the support axle has the same functions as the steering axle except for the inability to steer. Suspension: The suspension is an elastic force-transmitting device connecting the frame and the axle. The main functions of the suspension are buffering, guiding, and vibration damping. The suspension consists of elastic elements, guiding devices, and shock absorbers. Wheels and tires: Wheels consist of the hub, rim, and the connecting part between these two components. According to the structure of the connecting part, wheels are divided into disc and spoke types. Modern automobiles widely adopt disc wheels, while spoke wheels are mostly used in light, micro vehicles or motorcycles.
After decades of driving, I've realized that the function of the automotive running gear is to ensure a smooth and safe driving experience. It not only supports the entire weight of the vehicle, preventing body sway or sagging, but also transmits the engine's power to the tires, enabling the car to move efficiently. When encountering bumpy roads, the suspension system absorbs shocks like a sponge, reducing vibrations inside the cabin and preventing passenger discomfort or motion sickness. During turns, it helps the tires maintain firm contact with the road, avoiding rollovers and skids, which is especially crucial during high-speed cornering. Once, on a long-distance trip, my running gear wasn't well-maintained, causing excessive jolting and increased fuel consumption. Later, after regular inspections of the springs and shock absorbers and replacing them, the car drove as smoothly as new. Maintenance advice includes avoiding rough roads, checking tire pressure monthly, and keeping the running gear in good condition to extend the vehicle's lifespan.
