2. Working Principle
The whole vehicle operating system consists of five core linkage modules: full-drive off-road chassis bearing system, Weichai high-torque mechanical power system, full-axle power distribution system, multi differential lock traction system and hydraulic unloading system.
During operation, the optional 350HP/371HP Weichai Euro II mechanical pump engine burns low-quality overseas diesel stably via pure mechanical injection structure, without electronic sensor faults. The upgraded 371HP version outputs stronger low-speed torque, providing power guarantee for full-load climbing and heavy hydraulic unloading. Engine power is transmitted to 10-speed heavy manual transmission, part of power is split by built-in high-power PTO to drive front hydraulic cylinder for cargo tipping; the rest power is synchronously transmitted to front drive axle and dual rear drive axles to realize six-wheel synchronous power output.
When driving on slippery, muddy and desert soft roads, the inter-axle and inter-wheel multi differential locks automatically lock idle slipping wheels, evenly distribute driving torque to every single wheel, increase ground adhesion, and avoid vehicle trapping and sideslip. Benefiting from thickened double-layer riveted frame and balanced suspension, the chassis buffers violent bumping impact generated by rough roads, averts structural torsion and axle dislocation.
All three reinforced wheel-reduction drive axles share bearing pressure averagely, reducing long-term fatigue damage of single axle. Under downhill and heavy-load working conditions, matched braking system ensures stable speed reduction. The standard LHD design and complete export qualifications comply with traffic regulations and import policies of Africa, Central Asia and Southeast Asia, realizing legal cross-border operation.
