-Gearbox: 9-speed transmission, manually mechanical control by long distance soft axle, synchronizer is equipped. 

-Alxes: High strength axle with reliable performance, adopted oversea advanced technology and produced by famous company.

-Suspension Rear suspension,V-type thrust rod structure, and rubberspring suspension, to increase chassis driving stability and reduce tire wear.

-Tires: 315/80R22.5，×12

Reserve:315/80R22.5，×1

-Brakes: Service brake………foot pedal control, double-circuit air brake. The 1st circuit acts on the wheels of 1st axle, the 2nd circuit acts on the wheels of 3rd and 4thaxles. Parking brake………air-releasing brake, which acts on 3rd and 4thaxles. Auxiliary brake………engine cylinderinnerbrake and engine exhaust brake,safety and reliability and extend the service life of brake friction disc. 

-Steering: Mechanical steering system with hydraulic boosting device.
