DF3201TD-485 | Ordinary Bridge
DF3201TD-485 is the flagship through-drive double-drive axle for heavy trucks independently developed by Dongfeng Dana from 2011 to 2014, integrating American Dana drive technology.
The rated load is 16000kg×2 (the highest double axle load in the series), and it adopts 160×176mm high-strength press-welded axle shell (the largest cross-section in the whole series).
Equipped with an integral reducer housing to enhance rigidity, the gears utilize ultra-wide tooth face technology (wider than competitors by 10 mm or more), significantly reducing noise and prolonging life. Standard with a forced lubrication pump to optimize transmission efficiency.
The maximum torque of 50,000N-m×2, air brake (φ410×220) is suitable for 11.00R20 heavy-duty tires, and the wheelbase of 1860mm is fixed to meet the demand for efficient transportation of 16-60 tons of heavy trucks.
DF3201TD-485 Product Features
Adopting the integral reducer housing design to increase rigidity and reduce the risk of oil leakage;
The gears adopt the world’s leading high power density design technology, are lighter in weight, have a wide tooth surface design, are more than 10mm wider than competing products, and have lower noise;
Standard forced gear lubrication pump and oil channel inside the main shaft can effectively improve the lubrication of the shaft difference system, reduce shaft difference and cylindrical gear failure, and improve transmission efficiency;
Adopting fluororubber high performance oil seal design, tested according to DANA standards, the seal is more reliable
Optional maintenance-free wheel hub unit meets the matching requirements of high-grade commercial vehicles.
