What is the structure of a vehicle?

[VanRuby]

A vehicle is typically composed of four major parts: the engine, chassis, body, and electrical equipment. Here is the relevant information: 1. Engine: It includes the crank-connecting rod mechanism, valve train, fuel supply system, ignition system, lubrication system, cooling system, and starting system. 2. Chassis: It consists of the transmission system, running gear, steering system, and braking system. The transmission system transfers the engine power to the driving wheels and is composed of assemblies such as the clutch, gearbox, universal transmission device, and final drive. The running gear includes the frame, steering axle, drive axle, suspension, and wheels. The steering system is made up of the steering gear and steering mechanism. The braking system generally consists of two independent devices: the service brake system and the parking brake system. 3. Body and electrical equipment: The body is used to accommodate the driver, passengers, and cargo. The electrical equipment includes the power source, ignition system, starting system, as well as the vehicle lighting system, signal system, and instruments.
