DF0302D-285 | Bus Ordinary bridge

DF0302D-285 is one of the core products of Dongfeng Dana’s D285 series of lightweight drive axles, which is specially designed for the market of light trucks with a rated load of 3000kg.

It inherits American Dana’s high power density technology gene and combines with localized independent research and development to achieve a lightweight structure and high reliability with a punch-welded axle housing.

The fatigue life of the axle casing far exceeds the national standard and can reach more than 1.1 million times.

Suitable for GVW 4-6 tons models, it adopts φ300×75, 16″ oil brake, matched with 5.5J×16 rims and 7.00-R16 tires, with wheel bolts of 5-M18×1.5. The design takes into account the high performance and the convenience of arrangement, which is a powerful driving solution for 4-6 ton trucks.

DF0302D-285 Product Features

  • The axle housing features a lightweight, serialized design, facilitating vehicle layout and compatibility with multiple models.

  • Axle housing fatigue life: Averages over 1.1 million cycles at 2.5 times full load, far exceeding national standards.

  • The median fatigue life of the bevel gear gantry ranges from a minimum of 950,000 cycles to a maximum of 1.35 million cycles.

  • DANA’s patented high-power density gear and low-noise design technology reduces gear weight, improves gear strength, extends gear life, and reduces noise.
