I want to ask about the basic structure and model information of trucks.

Its structure is quite complicated, which can't be explained clearly in a few words. I can only say the main part! The number of parts of the whole vehicle is basically maintained at around 30,000, including tiny screws. The automobile structure is divided into four parts, and each part has a specific classification.

1. Engine: crank-connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system and ignition system starting system.

2. Chassis: The function of the chassis is to support and install the automobile engine, its parts and assemblies, to form the overall shape of the automobile, and to accept the power of the engine to make the automobile move and ensure normal running. The chassis consists of four parts: transmission system, running system, steering system and braking system.

3. Car body: The car body is installed on the frame of the chassis for drivers and passengers to ride or load goods. The body of a car and a bus is generally an integral structure, and the body of a truck is generally composed of a cab and a cargo compartment.

4. Electrical equipment: Electrical equipment consists of power supply and electrical equipment. The power supply includes storage battery and generator; Electrical equipment includes the starting system of engine, the ignition system of gasoline engine and other electrical equipment.
