How Many Parts Does a Vehicle System Consist Of?
2 Answers
A vehicle system is divided into 4 parts, including the running system, steering system, transmission system, and braking system. The running system consists of the frame, axle, suspension, and wheels (or tracks). Its functions are to receive the engine torque transmitted by the transmission system and generate driving force; bear the total weight of the vehicle, transmit and withstand the reaction forces and torques from the road acting on the wheels in various directions; provide cushioning and vibration damping to ensure smooth driving; and coordinate with the steering system to control the vehicle's direction. The steering system consists of the steering control mechanism, steering linkage, and steering gear. Its function is to ensure the vehicle can drive straight or turn as intended by the driver. The transmission system mainly consists of the clutch, gearbox, universal transmission device, and drive axle. Its functions are to reduce speed and increase torque; vary speed and torque; enable reverse driving; and, when necessary, interrupt the power transmission of the transmission system. The braking system consists of the energy supply device, control device, transmission device, and brake. Its functions are to decelerate and stop the vehicle and to provide parking braking.
From my driving experience, the vehicle system is mainly divided into several key parts, which help me handle daily maintenance with ease. The powertrain is the core, managing the engine and transmission to get the car moving; the chassis system handles suspension, steering, and brakes, ensuring a smooth ride; the body system includes the exterior shell and interior, affecting comfort and appearance; the electrical system controls all electronic gadgets, like the battery, lights, and dashboard. Each part is interconnected—for example, if the powertrain fails, the car won’t start. Understanding these helps quickly diagnose issues and avoid breakdowns on the road. When I check the oil or tires, I always take a look at the related systems, extending the vehicle’s lifespan and saving money in the long run.
