During this annual meeting, FAW Jiefang showed its impressive performance in 2021: the annual total sales volume was nearly 440,000 vehicles, nearly 370,000 medium and heavy trucks, and the share of medium and heavy trucks was 23.5%, setting another ten record highs and winning the first place in ten industries.
At the annual meeting site, 10 transmission products were grandly unveiled. Among them, the 12-speed AMT version/classic version of the transmission displayed by Jiefang Transmission, the 8-speed full synchronizer transmission, the lightweight 440 drive axle, the 300 lightweight wheel reduction bridge and the lightweight central integrated high-speed electric drive bridge were particularly eye-catching at the annual meeting site. It is these products that continue to help FAW Jiefang improve its product strength and provide strong support for Jiefang Vehicle to continue to lead the market. Let's take a look at the beautiful "report card" handed over by Jiefang Transmission under the general trend of energy conservation and emission reduction.
The centralized launch of lightweight products leads the general trend of industry development
Guided by relevant trends, China is committed to striving to reach the peak of CO2 emissions by 2030, and CO2 emissions per unit of GDP will be reduced by 60%-65% compared with 2005 in 2030, and achieve the ambitious goal of carbon neutrality by 2060.
Therefore, under the general trend of energy saving and emission reduction, the lightweight of vehicles is particularly important. To this end, Jiefang Transmission actively responded and successively launched a number of lightweight fist products.
Effective weight reduction 65kg lightweight 440 drive axle
As a new generation of drive axle independently developed by FAW Jiefang, Jiefang Drive's lightweight 440 drive axle can match J7, J6 and JH6 models, and its B10 life expectancy reaches 1.5 million kilometers. The maximum torque is up to 30000 Nm, the shaft load is rated at 13t, and the minimum speed ratio is only 2.389. The product applies high-performance gear oil, clean control technology, realizes 500,000 kilometers of long oil change of the transaxle, and adopts maintenance-free wheel units to effectively reduce the number of vehicle maintenance.

In addition, the lightweight 440 axle has reliable braking performance and a wide range of configurations, with a choice of high-performance wedge and disc brakes. The use of low-friction bearings, high-efficiency gear oil and high-precision gears greatly improves the drive axle transmission efficiency.
The product adopts high-strength steel plate stamping welding technology and compact shell design to achieve a lightweight weight reduction of 65kg, and at the same time, the application of international big brand products in bearings, oil seals and differential lock switches to improve product reliability.
300 lightweight wheel bridge effective weight reduction 126kg
At the annual meeting site, Jiefang Transmission also exhibited 300 lightweight wheel bridge reduction, using wheelside deceleration structure, greatly improving the output torque and vehicle passing performance, rated shaft load up to 16t, output torque 50000 N·m; The product applies lightweight integral cast iron bridge shell and integrated reducer shell to achieve a weight reduction of 126kg; Splash oil collection lubrication and open inter-shaft differential structure are adopted to effectively improve lubrication performance.
Jiefang Transmission 300 Lightweight Wheel Reduced Bridge
The product adopts the integrated technology of reducer housing and bearing housing, which reduces weight and greatly improves reliability; Differential locks between wheels and shafts are standard to meet the requirements of users under special working conditions; The use of high-strength brakes and variable-section friction pads makes driving safer and more reliable braking; In addition, a small speed ratio wheel side reducer is optionally installed to meet the special needs of the tractor.
An 8-speed fully synchronizer transmission with an aluminum shell weight reduction of about 50Kg
Jiefang Transmission's 8-speed full-speed synchronizer transmission is independently designed and developed by FAW Jiefang, and is a medium-sized vehicle transmission assembly with complete intellectual property rights. Its B10 has a life of 500,000 kilometers, an oil change cycle of 150,000 kilometers, and a more reliable quality, which can ensure the high attendance rate of the vehicle. More importantly, the product adopts the front, middle and rear shell barrel installation structure, which is compact, stiff and light, the iron shell is only 198kg, and the weight of the optional all-aluminum shell is reduced to 151kg.

In addition, the main and sub-boxes of the product adopt dual intermediate shaft, fine and high tooth design, large degree of coincidence, smooth meshing, can effectively reduce vibration and noise, stronger bearing capacity, the maximum input torque of 1100N·m. The main and secondary boxes adopt a full synchronizer structure and bearing support technology to improve the smoothness of the shift and make the product life longer. Moreover, its speed ratio is also more reasonable, the gradient is uniform, and it improves fuel economy while improving the smoothness of the shift, saving customers expensive fuel costs.
Product leadership Liberation Transmission Smooth Edition AMT
As the first high-end integrated 12-gear AMT product developed and built by FAW Jiefang using international advanced technology, Jiefang Transmission Changxing Edition AMT adopts a highly integrated electronic control system design, the product B10 has a life of 1.6 million kilometers, has a 5-year or 600,000-kilometer ultra-long oil change cycle, the amount of lubricating oil is as low as 7.5L, and it is also equipped with a maintenance-free self-adjusting clutch, which greatly improves the operation efficiency of the vehicle. With a number of unique functions such as automatic start and automatic return to the air, it is one of the most advanced 12-speed automatic transmission products in China.
Liberation Drive Freehand Edition AMT
Proven and reliable Transmission Classic Edition AMT
At the annual meeting site, another 12-speed automatic transmission - the classic version of the Liberation Transmission AMT is composed of the Liberation 12-speed manual transmission body + external automatic shift actuator + electronic control unit, the independent strategy meets the needs of users for a variety of operating scenarios, and the external structure makes maintenance more economical and convenient, the product is mature and reliable, and has been favored by a large number of users.
Liberation Transmission Classic Edition AMT
New energy weapon Light central integrated high-speed electric drive bridge
Under the general trend of energy conservation and emission reduction, electric drive is an important direction of development, and in this regard, Liberation Transmission is always moving forward.
Jiefang transmission light central integrated high-speed electric drive bridge
For new energy models, the need for lightweighting has become more urgent. The central integrated coaxial configuration system of the lightweight central integrated high-speed electric drive bridge of Jiefang Transmission is highly compact, and its parts are reduced by 40% and the reliability is increased by 10%. The product adopts a wide-area efficient drive motor and a coaxial planetary transmission mechanism, which greatly improves the transmission efficiency and significantly extends the driving range of new energy vehicles. At the same time, the product adopts platform design, optional liquid brake, air pressure drum brake, can meet the actual needs of different users.
Nowadays, FAW Jiefang strives to build a "smart power domain", leading the new 13L engine, integrated AMT transmission and the low-carbon power and new energy zero-carbon power of the 435 bridge, and at the same time strengthening the improvement of intelligent network technology to achieve the integrated collaborative control requirements of "man-road-vehicle-machine-chassis-bridge". Among them, Jiefang Transmission is continuously launching newer and better box axle products to help Jiefang vehicle achieve higher goals.
