DD502S | Steering axle

DD502S is a high-performance steering axle of the F5.0 series, adopting an I-beam structure, with a rated load of 5000kg (for heavy-duty demand).

It is equipped with a high-efficiency air brake system (adapted to 19.5° rim) as standard, and the key parameters are precisely optimized: fixed wheelbase of 2363mm to strengthen the stability, rim mounting distance of 2086mm for precise layout; main pin center distance of 1753mm to enhance the steering rigidity.

Exclusive design of 120+25mm front axle drop (the highest in the whole series), adapted with 7.50×19.5 rims and 245/70R19.5 wide base tires, the steering angle of the outer wheels reaches 49° (the top in the industry), and the bolts adopt 8-M20×1.5, which can satisfy the requirements of reliability and mobility of the commercial vehicles under complicated working conditions.

DD502S Product Features

  • Super Load Bearing: Flange-forged I-beam technology with load-bearing capacity covering 5.0 to 8.0 tons, suitable for ultra-heavy-duty scenarios such as ports and mines.

  • Heavy Load Braking: Standard equipped with large Ø420mm dual-chamber air brakes, with optional ABS and automatic adjusters, resistant to high temperatures and decay.

  • Structure Reinforcement: Wider wheelbase (1950-2200mm), axle housing made of high-strength alloy steel, increasing torsional resistance by 30%.

  • Long-term Maintenance: Integrated central lubrication system, upgraded sealing of key components, extending maintenance intervals to 5000km.
