DD1001TD-400 is a new generation of through-type duplex drive axle independently developed by Dongfeng Dana, specially designed for GVW 16-31 tons heavy-duty truck market.
With a rated load of 2×10,000kg, it adopts a reinforced press-welded axle housing (section 135×150mm), integrating high-capacity bearings and high-strength connecting parts, which significantly improves the stability of the system.
Low-noise gear design technology is utilized to extend the life and reduce the meshing noise; heavy-duty reinforced air brake (φ360×160、19.5,22.5″ rim) meets the needs of high altitude and emergency braking.
It is equipped with 8.5-20 rims and 11.00R20 tires with a wheelbase of 1855mm, and supports a maintenance-free wheel unit option.
DD1001D-400 Product Features
High-capacity bearings and high-strength connectors enhance system strength and reliability.
Low-noise gear design technology reduces connectors, lowering tooth contact and bending stresses, ensuring light weight, excellent rigidity, longer gear life, and reduced gear meshing noise.
Superior sealing design: Exceeds national standard certification requirements for extended mileage.
High-capacity drum brakes meet the vehicle’s system air pressure boost and high-altitude braking requirements, shortening stopping distances.
Optional maintenance-free hub units.
