The rear axle is Heavy Duty Truck AC16 type parallel duplex drive axle, the axle adopts large cross-section casting axle shell, and the maximum bearing tonnage of single axle is 16 tons.Howo 7 heavy duty dump truck drive axle adopts two-stage deceleration structure with speed ratio of 5.45, and the middle helical bevel gear main decelerator and the wheelside planetary decelerator carry out the double deceleration to increase the torsion, and at the same time it can also enhance the ground clearance of the axle.
Both front axles of Howo 7 heavy duty dump truck are HF9 type downward steering front axles of Heavy Duty Truck, with a single axle load of 9 tons, matched with 10-bolt steel wheels and 12.00R20 type steel wire tires for construction trucks.
