2. Working Principle
The whole vehicle working system consists of four core linkage modules: load-bearing chassis system, Weichai mechanical power output system, transmission power distribution system, safety braking and hydraulic unloading system.
During vehicle operation, the Weichai 350HP Euro II mechanical pump engine burns local low-quality diesel stably relying on pure mechanical fuel supply structure. It outputs sufficient high low-speed torque to cope with full-load starting and steep climbing; without electronic control components, it avoids flameout and fault alarm caused by impure fuel. The engine power is transmitted to the 10-speed heavy-duty gearbox, and the matched high-power PTO independently splits power and transmits it to the bottom hydraulic lifting device.
The hydraulic system drives the manganese steel cargo box to complete steady rear tipping unloading. Benefiting from 3825+1350mm standard wheelbase, the chassis disperses front and rear axle load evenly to prevent vehicle nose-lifting under full load. The thickened riveted frame cooperates with balanced suspension to offset torsion and road vibration, protecting chassis structure during long-term harsh working conditions.
When passing slippery and muddy mine roads, dual differential locks lock idle wheels to balance driving torque, prevent wheel slipping and vehicle trapping. In full-load downhill driving, full air brake cooperates with ABS and exhaust brake to realize linear speed reduction, avoiding brake failure risk. Standard LHD layout and complete export certificates ensure legal driving and customs clearance in overseas left-traffic countries.
