IF075-CD| Bus steering axle

The Dongfeng Dana IF075-CD Coach Axle is a high-end steering axle with a double wishbone structure, a rated load of 7500 kg, and a standard air brake system (compatible with 22.5″ wheel rims).

It uses a 2408 mm fixed wheelbase precision layout and 2066 mm wheel rim mounting distance to enhance rigidity, with a kingpin center distance of 1810 mm for precise control. The kingpin inclination angle of 8°/1° optimizes handling stability, with an inner wheel steering angle of up to 52° (industry-leading);

Compatible with 295/80R22.5 heavy-duty tires and 6.25×22.5 rims, featuring 10-M22×1.5 high-strength bolts combined with a φ285.75mm bolt distribution circle to ensure load-bearing safety, and supporting optional transverse stabilizer bars and maintenance-free hub units.

We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.
