What are the three major components of a car?

The three major components of a car refer to the engine, transmission, and chassis. Only with these three components can a vehicle operate; the absence of any one of them renders the vehicle inoperable. Below is a detailed introduction to the three major components of a car: 1. The engine, often referred to as the heart of the car, is the power source. Most car engines are thermal power devices, commonly known as heat engines. 2. The car's transmission is divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system. They achieve speed and torque variation through hydraulic transmission and gear combinations. 3. The car chassis consists of four parts: the transmission system, the running system, the steering system, and the braking system. The chassis supports and installs the car engine and its various components and assemblies, forming the overall shape of the car. It also receives the power from the engine, enabling the car to move and ensuring normal operation.
When it comes to the three major components of a car, I often discuss this topic with fellow car enthusiasts. Generally speaking, they refer to the engine, transmission, and chassis. The engine is like the heart of the car—it burns fuel to generate power and drives the vehicle forward. The transmission, on the other hand, is responsible for gear shifting and determines whether acceleration is smooth and the ride is comfortable. The chassis isn’t just a single plate; it includes the suspension, brakes, and steering system, all of which affect cornering stability and bumpiness. If any of these three components fail, the car won’t run properly—for example, an engine low on oil may emit black smoke, a jerky transmission makes driving difficult, and a loose chassis causes unsettling wobbling on the road. With over a decade of driving experience, I recommend regular maintenance: check the oil level monthly, avoid overloading, and get frequent wheel alignments. This way, the three major components will last longer, and safety is ensured. When choosing a car, pay attention to these three aspects—whether buying new or used, it’ll save you a lot of hassle.
