DF5001TD-300H | Ordinary Bridge
DF5001TD-300H is the flagship dual-stage wheel-side reduction drive axle designed for the extreme working conditions of heavy commercial vehicles.
The rated load is 25,000kg×2 (the highest in the series), and the maximum torque is 55,000N-m×2; it adopts 170×176mm high-strength casting axle shell (the largest cross-section in the whole series), and the integrated cast steel support frame at the wheel-side (the rigidity is increased by 30%).
Standardly equipped with through-wheel end lubrication system (significantly reduces temperature and extends gear life), matched with large-capacity air brake (φ410×220, 22.5″ rim). Equipped with 12.00R20 tires and 8.5V-20 rims to meet the demand of overload and extreme torque transportation in mines.
DF5001TD-300H Product Features
Strong load-bearing capacity and long gear fatigue life;
Through-lubrication system at the wheel ends reduces temperatures and extends the life of wheel-end gears and bearings;
The wheel-end reducer support frame utilizes a one-piece cast steel structure, enhancing overall wheel-end rigidity;
High-capacity, quick-change brakes and high-performance brake drums provide enhanced braking performance.
Optional high-performance oil seals and maintenance-free hub units meet the requirements of high-grade commercial vehicles.
