DF2601TD-440(Dual drive)|Ordinary Bridge
DF2601TD-440 is the flagship through-drive dual-drive axle for heavy-duty trucks independently developed by Dongfeng Dana in 2015-2017, incorporating American Dana’s high power density technology.
The rated load is 13000kg×2 (the highest in the series), suitable for GVW 11-49 tons long-distance heavy-duty transportation.
Adopting 135×150mm punch-welded axle housing, integrated monolithic housing design of main reducer, transmission efficiency is improved by 0.5~1% compared with competitors; weight of dual axle assembly is reduced by 140kg; maximum torque is 35,000N-m×2, speed ratio is 4.44-5.57 for flexible matching;
φ410×220 heavy-duty air brake (22.5″ rim) is equipped as standard; center distance of air chamber is 730-1246mm. Extra wide adjustable, providing a top load carrying solution for 6×4/8×4 models.
DF2601TD-440 (Dual – drive) Product Features
The final reducer assembly utilizes the DANA design concept—a high-power density design—to ensure torque transmission strength while maintaining a smaller footprint.
High transmission efficiency: 0.5-1% higher efficiency than competing products.
Lightweight design: The integrated reducer housing (no bearing seat) reduces the weight of the dual axles by 140 kg compared to competing products.
Low-noise gear design and manufacturing: leading noise levels among similar competitors.
Multiple optimized designs and product quality levels ensure more reliable axle assembly performance.
Optional maintenance-free hub units meet the requirements of high-end commercial vehicles.
