What Components Make Up the Automotive Running System?
2 Answers
The automotive running system consists of four main components: the frame, axles, suspension, and wheels. The frame serves as the foundational base for the entire vehicle assembly. The axles are connected to the frame via the suspension, and the wheels are mounted on the axles. The automotive suspension refers collectively to all power-transmitting connecting devices between the frame and axles. It elastically connects the axles to the vehicle body, mitigating the impact forces caused by uneven road surfaces during driving, thereby ensuring passenger comfort and cargo integrity. The primary functions of the automotive running system are to integrate the entire vehicle into a cohesive unit, support the total vehicle weight, receive torque from the transmission system, and generate traction between the driving wheels and the road surface.
The automotive running system mainly consists of four major components: First is the suspension, which acts like the 'legs and feet' of the car, absorbing vibrations from bumpy roads. After I replaced the springs on my car, it became noticeably more stable when going over potholes. Next is the wheel assembly, where tires and rims are responsible for transmitting power to the ground. When I switched to wider tires, the mechanic specifically mentioned the need to match the suspension parameters. The body structure serves as the 'skeleton,' with unibody construction being the current mainstream. My car's body is made of stamped steel plates welded together. Finally, there are the axles and steering knuckles, which you can clearly feel working in tandem with the tire's steering angle during turns. Poor coordination among these components can lead to issues like uneven tire wear or pulling to one side. Last time I got a wheel alignment, it took the whole afternoon to meet the standards.
