DF0402D-285 | Bus Ordinary bridge
DF0402D-285 is a mid-range drive axle in Dongfeng Dana’s D285 series. It incorporates Dana’s high-power density technology and is designed specifically for the 5-6 meter coach market.
Rated load capacity of 4,000 kg, featuring a lightweight stamped and welded axle housing (cross-section 102×102 mm), with an axle housing fatigue life exceeding 1.1 million cycles (2.5 times the national standard); bevel gear life of 950,000 to 1,350,000 cycles.
It supports dual braking systems (φ320×100 hydraulic brakes or φ310×160 air brakes, 16° flange), compatible with 7.50-R17.5 tires and 6.75×17.5 rims, with a wheelbase adjustable between 1,582.5 and 1,673 mm. Lightweight design combined with low-noise technology makes it an optimal solution for mid-to-high-end buses.
DF0402D-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.
