Transaxle(Ⅱ)
The drive axle is located at the end of the power transmission system, and its basic function is: ① to transmit the engine torque transmitted by the universal transmission device to the driving wheels through the main reducer, differential, half shaft, etc., to achieve speed reduction and torque increase; ② Changing the direction of torque transmission through the bevel gear pair of the main reducer; ③ By using a differential, the differential between the two wheels ensures that the inner and outer wheels turn at different speeds; ④ Load bearing and torque transmission are achieved through the axle housing and wheels

China's agricultural machinery industry still maintains a good growth rate
In recent years, under the continuous promotion of agricultural machinery purchase subsidy policies, China's agricultural machinery industry has been showing a high operating trend. In 2012, China's agricultural machinery industry still maintained a good growth rate. According to statistics, from January to November, the national agricultural machinery industry completed a total industrial output value of 283.259 billion yuan, a year-on-year increase of 19.61%, and completed a sales output value of 278.892 billion yuan, a year-on-year increase of 19.69%; The cumulative production and sales rate is 98.4%. After the autumn harvest, most agricultural machinery enterprises non-stop shifted their focus to production in the new year. With the acceleration of structural adjustment and technological innovation in the agricultural machinery industry, various enterprises have adjusted and optimized their production plans and human resources, organized production quickly, and prepared products for the market in 2013 in advance. The production of grain harvesters, which have experienced a decline in the market this year, has also increased by 10.33%, indicating that most agricultural machinery enterprises are still very optimistic and attach great importance to the market next year.
What is a drive axle
The drive axle is a mechanism located at the end of the power train that can change the speed and torque from the transmission and transmit them to the drive wheels. The drive axle is generally composed of the main reducer, differential, wheel transmission device, and drive axle housing. The steering drive axle also has a constant velocity universal joint. In addition, the drive axle also needs to withstand vertical forces, longitudinal and lateral forces, as well as braking torque and reaction forces acting between the road surface and the frame or body of the vehicle.
How to repair and maintain the front drive axle of a tractor(Ⅰ)
The normal functioning of various components of the tractor front drive axle is closely related to its proper use, maintenance, and repair. According to the introduction: During the use of the front drive axle, due to various adverse environmental factors, the connections between various components may become loose and the bearings may wear out. In addition, working substances such as lubricating oil and grease are gradually consumed, which disrupts the normal working conditions of the front axle. Therefore, maintenance technical measures such as tightening, adjusting, replacing, and adding must be taken in a timely and regular manner to maintain the normal working capacity of the components and extend the spare parts The service life of the component Therefore, the editor reminds users to carry out timely maintenance and upkeep of the tractor front drive axle according to the following instructions:

How to repair and maintain the front drive axle of a tractor(Ⅱ)
Regularly clean the impurities and soil around the oil cylinder cover to prevent damage to the piston rod of the oil cylinder due to excessive soil and other debris. If the oil cylinder leaks, it will cause difficulty or failure in steering;? Regularly clean the impurities and soil around the ventilation plug to prevent blockage of the ventilation plug due to debris such as soil. Blocking the ventilation plug will cause an increase in the internal air pressure of the front drive axle, which can easily cause damage to various seals;? Regularly clean the impurities and soil around the oil cup. Blocking the oil cup will result in the inability to add lubricating grease.
