DF271S | Steering axle

DF271S is a high-performance steering axle with an I-beam structure and a rated load of 2700kg (leading in its class).
It is equipped with air brake braking system (φ310×100 special specification, 17.5° rim) as standard, wheelbase supports 1754-2468mm ultra-wide adjustment (the largest range in the industry), and rim mounting distance covers 1500-2120mm flexible layout.
The center distance of main pin is 1390-1737mm to optimize the steering performance, and the front axle drop is 83+12mm to enhance the passability.
Adapted with 6.00×17.5 rims and 215/75R17.5 wide base tires, the main pin tilt angle is 12°/camber angle is 0.5°, and the steering angle of the outer wheels is as high as 40 °.
The bolts support the dual specifications of 6-M18×1.5 or 6-M20×1.5, which guarantees the stable transportation of heavy loads.

DF271S Product Features

Adopting the integral reducer housing design to increase rigidity and reduce the risk of oil leakage;
The gears adopt the world’s leading high power density design technology, are lighter in weight, have a wide tooth surface design, are more than 10mm wider than competing products, and have lower noise;
Standard forced gear lubrication pump and oil channel inside the main shaft can effectively improve the lubrication of the shaft difference system, reduce shaft difference and cylindrical gear failure, and improve transmission efficiency;
Adopting fluororubber high performance oil seal design, tested according to DANA standards, the seal is more reliable
Optional maintenance-free wheel hub unit meets the matching requirements of high-grade commercial vehicles.
