Chassis

Transmission system

■ Gearbox: Manual gearbox is adopted with 9-gear and large speed ratio range applied,

which meets the requirements of low gradeability speed and high traveling speed.

■ Transmission shaft: With optimized arrangement of the transmission shaft, the transmission

is stable and reliable. For most optimized transmission, face-tooth coupling transmission

shaft is used with large transmission torque.

11800～45000

Brakes system

■ Air servo brakes are used for all wheels with dual-circuit brake system applied, engine is

equipped with an exhaust brake.

■ Brakes system includes traveling brake, parking brake, emergency brake and auxiliary

brake.

■ Traveling brake: All wheels use the air servo brakes and dual-circuit brake system.

■ Parking brake: Force driven by accumulator is applied on the third to fourth axle.

■ For emergency brake, accumulator is used not only for cutting-off brake but also for

emergency brake.

■ Auxiliary brake is exhaust brake with brake safety ensured while travelling downhill.
