Detailed Explanation Of The Construction Of Agricultural Tractors

1. Introduction
Agricultural tractor is an important machinery in the process of agricultural production, mainly used for farming, transportation and other work, is the farmer's right-hand man. The structure of agricultural tractors mainly includes elements such as engine, gearbox, transmission shaft and drive axle, and we will introduce their structure and functions separately below.
Second, the engine
The engine of an agricultural tractor is its heart and the source of its power. The engine is usually a diesel engine, which has the characteristics of high torque and strong load capacity. At the same time, diesel engines are more durable and economical than gasoline engines. The structure of the engine mainly includes cylinders, pistons, crankshafts, intake pipes and exhaust pipes, each of which has its own unique role.
3. Gearbox
The function of the gearbox is to change the speed ratio between the output shaft and the input shaft through the combination of different gears, so that the agricultural tractor can adapt to different working conditions. The gearbox structure consists mainly of axle holes, which are fixed by hanging on the frame, and mandrel, which are directly embedded in the axle holes.
Fourth, the transmission shaft
As the connecting part of the agricultural tractor, the transmission shaft plays the role of connecting the gearbox and the drive axle. The transmission shaft often adopts the steering mechanism of universal joint to adapt to the steering angle required by the wheel in different working processes. The structure of the transmission shaft is simple, mainly composed of mandrel and universal joint.
5. Drive axle
The drive axle is the last part of the agricultural tractor, and its role is to transfer the kinetic energy of the propeller shaft to the wheels. The structure of the drive axle is mainly composed of a differential and assembly components. The function of the differential is to transfer power to each wheel, and the assembly includes the axle, end axle and universal joint.
