Dual-core upgrade: wet brake + electronic differential lock, crack the pain points of the operation

The core breakthrough of the T400s high-horsepower tractor drive axle lies in the innovative installation of two core configurations, wet braking and electronic differential lock, which accurately solves the industry pain points such as insufficient braking performance of traditional tractor drive axles and poor passability of complex road conditions, so that high-horsepower tractors have more advantages in various farming scenarios, and further consolidates Shandong Lutong's leading position in the field of tractor drive axles and high-horsepower tractor drive axles. In the leading position of technology in the field of tractor drive axles and high-horsepower tractor drive axles.

Wet braking: efficient and stable, suitable for extreme working conditions

The wet braking system equipped with the T400s tractor drive axle adopts a fully enclosed structure design, and the brake components are placed in a special oil environment to operate. Compared with traditional dry braking, it has three significant advantages.

• First, the heat dissipation efficiency is excellent. The heat generated during braking can be quickly transmitted and dissipated through the oil. Even in long-term high-load operation scenarios, stable braking performance can always be maintained to avoid brake attenuation caused by overheating, and the brake temperature is controlled within a safe range to ensure the safety of operations in all directions.

• The second is the outstanding protection performance. The closed structure can effectively isolate the erosion of farmland mud, dust, debris, etc., reduce the wear of brake components, extend the service life, reduce equipment maintenance costs, and perfectly adapt to all kinds of complex farming environments.

• Third, the braking force is strong and stable. It adopts a multi-piece friction structure design, which can provide sufficient braking torque, respond quickly and brake smoothly. Even under harsh working conditions such as heavy-duty operations and long-slope driving, precise braking can be achieved, ensuring the safety of operators and equipment in all directions, and greatly improving the reliability of tractor operations.

Electronic differential lock: intelligent escape, improve traffic capacity

In view of the problem that tractors are easy to slip and difficult to get out of trouble under complex road conditions such as muddy, slippery, steep slopes, etc., the T400s high-horsepower tractor drive axle is equipped with an intelligent electronic differential lock (EDS), which is an extension function of the ABS system. It can realize intelligent response in milliseconds and monitor the difference in wheel speed on both sides in real time.When one-sided wheel slippage is detected, the system automatically applies braking to the slippage wheel, accurately allocates power to the attached wheel, and forces the wheels on both sides to rotate synchronously and work together to completely solve the industry problem of “single-wheel idling, the whole vehicle is trapped”, greatly improving the tractors' passability and ability to get out of trouble.The electronic differential lock adopts fully automatic intelligent control without manual operation. It automatically starts when the speed is below a reasonable range and automatically releases when driving normally. It can not only adapt to heavy-duty operations such as deep loosening of farmland and joint land preparation, but also easily cope with complex scenarios such as cross-axles and muddy roads, making tractors smoother and more efficient in operation.

Global optimization, multiple adaptations--Comprehensive performance analysis of T400s

In addition to the core upgrade of dehumidification braking and electronic differential lock, the T400s high-horsepower tractor drive axle completes the optimization of all-dimensional details and overall performance on the basis of the T400 tractor drive axle. It has become the preferred Farm Implement Axles product for 400-horsepower tractors.

In terms of transmission performance, the T400s tractor wet drive axle continues the Gleason arc bevel gear transmission design used in the T400 tractor drive axle. The gear system is developed by Gleason Company in the United States. The gear line is an arc structure and is processed by professional gap indexing method. It has the core advantages of high transmission efficiency, stable meshing and strong carrying capacity.Compared with the T400 tractor drive axle, T400s has optimized the transmission structure in detail, so that its transmission efficiency has exceeded 98%, the operating noise is further reduced than before, and the energy consumption is smaller, which effectively reduces the fuel consumption during tractor operation and significantly improves the operating efficiency; the wheel side adopts the “NGW type” planetary deceleration structure, which has a compact structure, stable output, and high carrying capacity.

In terms of quality and reliability, the T400s tractor drive axle adopts a high-strength cast steel axle shell, which has strong rigidity and excellent impact resistance, and can withstand the pressure of long-term heavy-duty operations of high-horsepower tractors. The sealing structure is fully upgraded, and the dustproof and waterproof performance is greatly improved. It can be adapted to the operating environment of different regions such as Russia's severe cold, windy and sandy in the north of the country, and rainy in the south, ensuring long-term stable operation of products under complex working conditions, and the product pass rate is stable at more than 99.8%.

As an upgraded high-horsepower tractor drive axle, T400s can not only be perfectly adapted to various types of tractors of the 400 horsepower class, but also can be customized and adapted according to the individual needs of customers, taking into account agricultural operations and some engineering auxiliary operation scenarios, to realize the diversified application of tractor drive axles, and further broaden the scope of application of agricultural machinery drive axles.At present, the product has been installed in the PTZ manufacturer to carry out trial work. During the trial period, its upgraded wet braking, electronic differential lock performance and optimized transmission performance have all reached the expected standards, and it has been preliminarily affirmed by the technical team of the PTZ manufacturer.
