DF0651D-310 | Bus Ordinary bridge

DF0651D-310 is Dongfeng DANA’s flagship drive axle, introducing American DANA high power density technology, specially designed for 6-8 meter high-end coaches.

With a rated load of 6500kg (the highest in the D310 series), it uses a 110×120mm reinforced stamped and welded axle housing with a fatigue life of over 800,000 cycles. Innovative integrated design of the differential’s driven wheel and left housing significantly reduces noise to 70 dB (industry benchmark) and extends gear life by over 30%.

Maximum torque of 15,000 N·m, compatible with both hydraulic and air braking systems (φ310×120, 17.5″ rim), with wheelbase adjustable from 1,662 to 1,800 mm, paired with 215/75R17.5 tires, providing the bus market with top-tier load-bearing and noise-reduction solutions.

DF0651D-310 Product Features

  • The integrated design of the differential’s driven gear and left housing reduces connecting parts, lowering contact and bending stresses on the tooth surfaces. This ensures light weight, excellent rigidity, extended gear life, and reduced gear meshing noise.

  • The axle housing has an optimized cross-sectional modulus, enhancing the rear axle’s load-bearing capacity and achieving a fatigue life of over 800,000 cycles.

  • Utilizing DANA gear design, manufacturing, and testing technology, noise levels are as low as 70dB.

  • The lightweight design makes the rear axle assembly over 10kg lighter than similar axles.
