DF0801D-350 | Ordinary Bridge

DF0801D-350 is a high-end drive axle for medium trucks independently developed by Dongfeng Dana, designed for GVW 9-14 tons heavy-duty market.

With a rated load of 8000kg, it adopts the integrated design of differential passive wheel and left casing, which significantly reduces noise and extends gear life by 30%.

Optimized 120×135mm punch-welded axle housing (with better cross-section coefficient) achieves high rigidity and light weight reduction.

The air brake system covers φ400×155/φ400×180 dual specifications (19.5″ rim), with maximum torque of 18,000-20,000N-m, adapted to 7.00-20 rims and 9.0-20 tires, to meet the needs of heavy-duty scenarios such as coal transportation.

DF0801D-350 Product Features

  • The integrated design of the differential’s driven gear and left housing reduces connecting parts, lowering tooth contact and bending stresses, ensuring low weight, excellent rigidity, longer gear life, and reduced gear meshing noise.

  • The axle housing has an optimized cross-section modulus, enhancing rear axle load capacity.

  • Superior sealing design: Exceeding national standards and certification requirements, ensuring longer mileage.
