What Are the Three Core Components of a Car?

[IsabelaLee]

The three core components of a car refer to the engine, chassis, and transmission. Here are the detailed introductions: Engine: An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), and electric motors. Car Chassis: The car chassis consists of four parts: the transmission system, running system, steering system, and 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 to make the car move and ensures normal driving. Transmission: It is divided into manual and automatic types. The manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations. The automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque system, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.
