The use of all-around elastic suspension greatly reduces the vibration of the whole machine and the fatigue damage caused by resonance reduces the fatigue strength of the driver and improves the driving comfort of the driver. It has high reliability, high adaptability, low fuel consumption, and low emission. advantage. Intelligent independent heat dissipation system with positive and negative reversal, suction type single-row radiator, integrated air-conditioning condenser, good heat dissipation effect, energy saving, and consumption reduction.
Transmission system: ZF automatic gearbox, hydraulic mechanical transmission, power gear shift, can make full use of engine power so that the whole machine has greater traction; it can adapt to the constant changes of external resistance, and can achieve stepless speed change, reducing Frequent gear shifting impacts the transmission components and the engine; a dust-proof large-flow respirator is applied to the gearbox, which is easy to maintain and improve the cleanliness and reliability of the gearbox. The ZF wet drive axle with high load-bearing capacity is adopted, and the front axle has a limited-slip differential function, which makes the powerful traction of the whole machine easier to play, with and at the same time improves the trafficability of the whole machine; the key block type construction machinery transmission shaft has strong impact resistance and power reliable delivery.
Frame: The front and rear frame articulated opening distances are increased, the upper and lower articulations adopt double-row tapered roller bearings, the matching tolerances are optimized and improved, and the articulation is reliable; the front frame adopts a four-plate tailor-welded structure, and the rear frame is a single-plate structure. The frame has good overall rigidity and strong bearing capacity; the frame adopts finite element analysis and design, focusing on the overall structural strength, reducing stress concentration points, and eliminating local weaknesses; the key structure front axle is installed with a U-shaped plate reinforced structure and a tipping cylinder support The seat adopts a box-shaped reinforced structure with reliable performance; the whole is manufactured by a flexible welding process, which has stronger impact resistance and ensures that it can meet various dangerous and heavy working conditions.
Hydraulic system: Electro-hydraulic proportional control full variable load-sensitive dual-pump confluence hydraulic system, flow, and pressure are self-applicable to load requirements, overcome overflow loss, minimize energy loss, and improve hydraulic system work efficiency. Adopting a full variable dynamic load-sensitive flow amplification steering hydraulic system and electro-hydraulic proportional control working hydraulic system, the handle is easy to operate, reducing the driver’s work intensity; the high hydraulic oil tank, the compact structure of the whole machine, enhances the pump’s oil absorption capacity, and improves the hydraulic pressure System stability; equipped with stability module function to ensure the stability of the vehicle during high-speed driving and material transportation, and improve work efficiency; emergency steering power source in the form of electric pump, controlled by the controller signal, safe and reliable, equipped with independent heat dissipation system, electronic control The technology intelligently adjusts the fan speed and saves energy consumption so that the heat dissipation of the whole machine is always processed in the best state. The whole machine has a wet brake, and the foot brake valve integrates the parking brake and brake light pressure switch, which is easy and safe operation.
