Tractor is a self-propelled power machine used to tow and drive working machinery to complete various mobile operations. Can also be used for fixed operation power. It consists of engine, transmission, walking, steering, hydraulic suspension, power output, electrical instruments, driving control and traction and other systems or devices. The engine power is transmitted to the drive wheels by the transmission system to make the tractor run. In real life, it is common to use rubber belts as the power transmission medium. It is divided into agricultural, industrial and special purpose tractors according to functions and uses; it is divided into wheeled, tracked, boat-shaped tractors and self-propelled chassis according to the structure type.
Although a tractor is a relatively complicated machine, its type and size are also different, but they are composed of three major parts of the engine, chassis and electrical equipment, each of which is indispensable.
engine
It is a device for generating power for tractors, and its role is to convert the thermal energy of fuel into mechanical energy to output power. Most of the agricultural tractors produced in China use diesel engines.
Chassis
It is a device that transmits power to a tractor. Its role is to transmit the power of the engine to the driving wheels and working devices to make the tractor run, and complete the mobile operation or fixed role. This effect is achieved through the cooperation and coordination of the transmission system, the walking system, the steering system, the braking system, and the working device. At the same time, they form the skeleton and body of the tractor. Therefore, we collectively refer to the above four systems and a large device as the chassis. In other words, in the entire tractor, all systems and devices other than the engine and electrical equipment are collectively referred to as the tractor chassis.
electrical equipment
It is a device that guarantees electricity for tractors. Its role is to solve the lighting, safety signals and engine starting.
