Tractor is a self-propelled power machine used to tow and drive working machinery to complete various mobile operations. It can also be used for fixed homework power. It is composed of systems or devices such as engine, transmission, walking, steering, hydraulic suspension, power output, electrical instruments, driving control, and traction. The engine power is transmitted from the transmission system to the drive wheels to drive the tractor. In real life, rubber belts are commonly used as the medium for power transmission. Tractors for agriculture, industry, and special purposes are classified according to their functions and purposes; According to the type of structure, it is divided into wheeled, tracked, boat shaped tractors, and self-propelled chassis.
Although tractors are a relatively complex machine with different types and sizes, they are all composed of three major parts: engine, chassis, and electrical equipment, each of which is indispensable.
The engine is a device used by tractors to generate power, and its function is to convert the thermal energy of fuel into mechanical energy to output power externally. Most agricultural tractors produced in China use diesel engines.
The chassis is a device used by tractors to transmit power. Its function is to transmit the power of the engine to the driving wheels and working devices to drive the tractor, and to complete the moving or fixed function. This function is achieved through the mutual cooperation and coordination of the transmission system, walking system, steering system, braking system, and working device, which also form the skeleton and body of the tractor. Therefore, we collectively refer to the four major systems and one major device mentioned above as the chassis. That is to say, in the overall tractor, all other systems and devices, except for the engine and electrical equipment, are collectively referred to as the tractor chassis.
Electrical equipment is a device that ensures the power consumption of the tractor. Its function is to solve lighting, safety signals, and engine starting.
