What is an automotive structure?

Automotive structure refers to the core components and functional systems that make up a vehicle, primarily consisting of four major modules: the engine, chassis, body, and electrical equipment. As the power core, the engine converts chemical energy into mechanical energy through the combustion of petrol or diesel. Its internal components include the crankshaft-connecting rod mechanism, valve train, and auxiliary systems such as cooling, lubrication, and fuel supply, ensuring efficient operation. The chassis serves as the framework supporting the entire vehicle, comprising the transmission system (e.g., clutch, gearbox), running gear (suspension, wheels), steering system (steering wheel, steering gear), and braking system (brake disc, brake assembly), all of which collectively ensure driving stability and handling. Its construction includes components such as doors, roof, and fenders, which directly impact safety and spatial arrangement. The electrical system encompasses power sources (battery, alternator) and electrical devices (ignition system, lighting, air conditioning, etc.), providing support for vehicle startup and electronic functionalities. Additionally, modern vehicles are equipped with passive safety features such as airbags and seat belts. Understanding its structure facilitates routine maintenance and troubleshooting.
