The three major parts of a car are: engine, chassis, and gearbox.
1. Engine
An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine applies to both the power generating unit and the entire machine including the power unit (eg gasoline engine, aircraft engine). The engine was first born in the United Kingdom, so the concept of the engine is also derived from English, and its original meaning refers to the kind of "mechanical device that generates power".
The body is the skeleton that constitutes the engine, and is the installation base of the various mechanisms and systems of the engine. All the main parts and accessories of the engine are installed inside and outside it, and bear various loads. Therefore, the body must have sufficient strength and rigidity. The body group is mainly composed of cylinder block, cylinder liner, cylinder head and cylinder gasket and other parts.
2. Automobile chassis
The automobile chassis is composed of four parts: drive train, driving train, steering train and braking train. The role of the chassis is to support and install the car engine and its components and assemblies, form the overall shape of the car, and accept the power of the engine to make the car move and ensure normal driving.
3. Gearbox
It is divided into two types: manual and automatic. The manual transmission is mainly composed of gears and shafts, and the variable torque is generated through different gear combinations; while the automatic transmission AT is composed of a hydraulic torque converter, a planetary gear, a hydraulic pitch change system and a hydraulic The control system is composed of hydraulic transmission and gear combination to achieve variable speed and torque.
The functions are: 1. Change the transmission ratio; 2. Under the condition that the rotation direction of the engine remains unchanged, the car can run backwards; power output.
