DF271S | Bus 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
Craftsmanship and Load Capacity: Features a flange-forged I-beam structure with advanced technology, offering solid and reliable load-bearing capacity, covering 2.5 to 3.2-ton requirements.
Braking Performance: Standard equipped with air brake calipers (e.g., the F2.7 series uses Ø420×80 specifications), with optional ABS anti-lock braking system and automatic brake gap adjusters for efficient and stable braking.
Lightweight and Adaptability: Lightweight bridge design with adjustable kingpin and wheelbase, suitable for various commercial vehicle scenarios.
Maintenance Convenience: Requires the application of No. 2 lithium grease every 2000km, with long-lasting key components to reduce operational costs.
