Dongfeng new generation of high-end axle production! Which models will TA be equipped with?

According to China Truck Network, we learned that the new high-end axle product TD440 is in mass production. TD440 is a high-efficiency highway built by Dongfeng Dana Axle Co., Ltd. based on the advanced development experience of Dana Corporation in the United States and combined with the actual operating conditions in the Chinese market. Double drive axle.

Performance characteristics:

The main reducer assembly adopts the DANA design concept: the high power density main reduction assembly design ensures the twisting strength while the structure size is smaller.

Lightweight design: High power density gears and bearings, the lightest weight of the TD440 compared to statistical competition.

High transmission efficiency: Small speed ratio design, compared with competing products of the same level, the TD440 has the smallest speed ratio and the highest assembly transmission efficiency. The minimum speed ratio of the double bridge can reach 2.56.

High maintenance mileage: 100,000Km oil mileage.

NVH: Low-noise gear design and manufacturing, compared with its competitors, TD440 noise level is leading.

Rebuilt reducer assembly line

At present, Dongfeng Dana Axle Co., Ltd. has entered the mass production phase of the new high-end axle product TD440. TD440 series bridges are the main products of Dongfeng Dana Axle Company in the future. As soon as possible, the company will increase the production capacity and seize the market. This is undoubtedly the highlight of the company's development, and the production bottleneck of TD440 series bridges is in the production of reducer assembly.

According to Zhao Xiyi, chief engineer of Dongfeng Dana Axle Co., Ltd., the TD440 is a high-end axle matching the Dongfeng Tianlong and Dongfeng Tianlong flagship models of the mainstream models of Dongfeng Commercial Vehicle Co., Ltd. Recently, the test vehicle has been put into the market for verification and has received better user feedback.

Dongfeng Dana Axle Company Shiyan Factory Production Site

In the first half of this year, the Dongfeng Dana Axle Co., Ltd. Shiyan plant has been in high production. In order to avoid the problem of high-yield and new-product zippers, the factory set up a TD440 project team in February of this year, and built a high-grade 485 reduction line. Automated, highly flexible and highly reliable reducer assembly line. In October and November two months, the factory reducer workshop employees also performed the zipper assembly and production of the TD440 reducer assembly while fulfilling the established production tasks. They gave up the two-day holiday, and the new production was made as soon as possible.

Zhang Wenyu, decelerator workshop manager of the Dongfeng Dana Axle Company's Shiyan Plant, introduced that through the production zippering, the problem was constantly rectified. With the elimination of problem points and the improvement of staff assembly skills, the production capacity of the TD440 series reducer assembly is steadily increasing. With the production bottleneck open, the production capacity of the TD440 rear axle and Zhongqiao has approached 60% of the process design capacity.
