Liugong CLGB320C bulldozer is a high-horsepower bulldozer independently developed by Liugong with reference to the advanced design and manufacturing technology of foreign bulldozers. The whole machine has advanced and reasonable structure, easy and flexible operation, and high production efficiency.
1. The whole machine has the advantages of advanced structure, reasonable layout, labor-saving operation, low fuel consumption, convenient operation and maintenance, stable and reliable quality, and high work efficiency. It can be equipped with various devices such as traction frame, coal shovel, ripper and winch. , can adapt to various working conditions.
2. The Cummins NTA855-C360S10 diesel engine with fast response performance is combined with a hydraulic torque converter and a power shift gearbox to form a powerful transmission system, which shortens the working cycle and improves work efficiency. The liquid medium transmission can play an overload protection role under heavy loads, so that the components of the transmission system are protected from damage and the service life is extended.
3. The hydraulic torque converter enables the output torque of the bulldozer to automatically adapt to the change of the load, protects the engine from overload, and does not stop the engine when it is overloaded. The planetary powershift transmission has three forward gears and three reverse gears for quick shifting and steering.
4. The design of instrument components is simple and clear, mainly used to monitor engine coolant temperature, engine oil pressure, transmission oil temperature and electrical instruments. The B220 dozer is packed with performance features for high productivity and reliability. It can fully meet the user’s job requirements and help users obtain the highest return on investment.
5. High reliability and long service life.
6. Strong power and quick response. The direct fuel injection system maximizes the energy of every drop of fuel.
7. Good economy, low fuel and engine oil consumption – the minimum fuel consumption is less than 212g/kw h. Green, environmentally friendly, high-efficiency exhaust gas turbocharger improves combustion, reduces specific fuel consumption, and has good emission indicators.
8. Green, environmentally friendly, high-efficiency exhaust gas turbocharger improves combustion, reduces specific fuel consumption, and has good emission indicators.
9. B320 bulldozer power shift transmission is planetary gear type, manual hydraulic shift, forced lubrication, 3 forward gears, 3 reverse gears. The switching of direction and speed is achieved through the control valve to engage or disengage the 5-row friction plate clutch in the box, which reduces the shifting time and improves the shifting efficiency. High transmission efficiency, compact structure and small volume.
10. The central transmission of the B320 bulldozer is a spiral bevel gear with splash lubrication. Among them, the large spiral bevel gear is placed on the left side of the output shaft of the gearbox, which greatly improves the stress condition of the output shaft of the gearbox and increases the service life of the output shaft of the gearbox.
11. The steering clutch of the B320 bulldozer is a constant mesh hydraulic separation clutch with high reliability. The structural form adopts wet type, multi-plate, spring pressure, manual operation (linkage with brake), hydraulic power assist. The power of the transmission is divided into left and right through the central transmission, and then transmitted to the final drive through the left and right steering clutches. The steering clutch is equipped with a forced lubrication system, and the lubricating oil can directly enter the joint surface of the friction plate, which not only plays the role of forced lubrication, but also plays the role of cooling and heat dissipation, thereby improving the service life and ensuring low temperature rise of the hydraulic system.
