DD0601D-350/Bus Standard Axle
The Dongfeng DANA Coach Axle DD0601D-350 is specially developed for the 7-9 meter coach market, with a rated load of 6500kg, using a 120×135mm high-strength stamped and welded axle housing (with a fatigue life 2.5 times that of competing products).
Integrating DANA’s low-noise, high-power-density technology: gear noise is 2-4 decibels lower than competitors, the assembly is lightweight with a weight reduction of over 30 kg, the reverse torque is increased by 10% to optimize new energy efficiency, and the maintenance mileage exceeds 100,000 kilometers.
Standard air brake system (optional specifications: φ310×160, φ360×160, or φ400×180, compatible with 19.5″ wheel rims), supporting flexible adjustment of wheelbase from 1680 to 1720 mm. It is paired with 6.75×17.5 wheel rims and 215/75R17.5 tires, with optional maintenance-free hub units.
DD0601D-350 Product Features
The axle housing has a better cross-sectional coefficient, the rear axle has a stronger load-bearing capacity, and the fatigue life is 2.5 times that of competing products.
Adopting DANA gear design, manufacturing and testing technology, the noise level is 2-4 decibels lower than that of competing products.
Lightweight design, the rear axle assembly is more than 30Kg lighter than similar axles.
High power density design increases anti-drag torque by 10%, which helps improve the economy of new energy vehicles.
The maintenance interval mileage has been increased to four times the original time, reaching 100,000 kilometers.
