The overall structure of a car is basically composed of four parts: engine, chassis, body, and electrical system. The following is an introduction to automobile construction: 1. Introduction: A car is a non-rail, non-catenary vehicle that is driven by its own power unit and has four or more wheels. 2. Purpose: The main purpose of a car is transportation, that is, to carry people and goods. 3. Difference: Cars are different from trains running on laid tracks or electric catenaries, trams and trolleybuses, tractors for farmland operations, and self-propelled construction machinery. In classification statistics, two-wheeled or three-wheeled motor vehicles, and combat vehicles with weapons and armor are not considered cars.

As a seasoned driver with years of experience, I always say that a car's structure can be divided into several main parts. The body is like the car's outer coat, protecting the interior from damage; the engine is the heart, responsible for providing power; the drivetrain includes the transmission and drive shafts, delivering power to the wheels; the chassis features the suspension system, reducing vibrations when the car bumps; the braking system controls speed and ensures safe stopping. There's also the electrical system, like the battery and wiring, managing functions such as lights and the horn. Tires are crucial too, as they make direct contact with the road. Inside the body, there are the dashboard and seats, providing a comfortable driving environment. Overall, these parts work together seamlessly, and none can be overlooked. During routine maintenance, I focus on checking engine fluids and brake pads to ensure driving safety.

I'm particularly fascinated by the mechanical structure of cars, it's so cool! The core component is the engine, which burns fuel to propel the vehicle; the transmission system includes the clutch and gears to adjust speed; the chassis bears all the weight and includes the suspension to absorb road conditions; the braking part uses brake discs to slow down; the electrical system controls the air conditioning and instrument display. I also enjoy studying auxiliary parts like the exhaust pipe and fuel system, which affect performance and environmental friendliness. When designing a car, a high chassis rigidity can enhance handling, and the engine layout balances the center of gravity. I often disassemble and assemble small parts for fun—these structures make driving more enjoyable, like the precise rotation of transmission gears that keeps me hooked!

Over decades of repairing cars, I've seen that a car's structure is quite straightforward: the engine handles power; the transmission changes speed; the chassis supports the wheels and suspension; the electrical system connects and controls various functions; the body provides a protective shell; and the braking system ensures safe deceleration. Common trouble spots include engine oil leaks or electrical short circuits, and I teach car owners to check the oil dipstick and fuse box. Structurally, it includes exhaust pipes and seat belt anchor points, which affect performance and durability. For daily inspections, I recommend focusing on vulnerable areas like brake disc wear and body rust spots, as these can prevent major overhauls.
