Bulldozer is a blade mounted on the front tractor loaded Road Machinery

Track Dozer is an engineering vehicle, equipped with a large metal front dozer blade, dozer blade down when in use, chipping and push forward the mud, sand and stones, dozer blade position and angle can be adjusted. Swamp hydraulic track dozer can do it alone excavators, earth and dump work, with flexible operation, convenient rotation, the Face little need, driving speed and other characteristics. It is mainly applied to three types of soil in a shallow cut short transport, such as land clearing or leveling, excavation depth of excavation and backfill little push to build highly little roadbed.

Hydraulic crawler bulldozer in front of a tractor loaded blade mounted road construction machinery, for bulldozing, leveling the building venues. For example, in the construction of the road construction, the bulldozers can complete the process of subgrade, roadside soil lateral Tim building height of not more than one meter of embankment along the centerline of the road to shoveling transfer, transport roadbed soil excavation and filling works, take the mountain construction of part - cut soil subgrade. In addition, the bulldozer can be used for leveling the ground and accumulation of loose materials, removal of obstructions in the work area and the like.

When the Mechanism drive Bulldozer  issue abnormal sound gear shifting, difficult Nie Kazakhstan
Main reasons: to adjust the dish too tight; adverse effect of the hand brake. When adjusting plate tight, clutch master more difficult, and therefore can not cut off the power, resulting in abnormal noise when shifting gears. In this case, adjust the dial to adjust counterclockwise position, namely adjustment Bulldozer with Universal Blade main clutch, just pull the handle when the master clutch can clearly hear the voice ringing across the dead can be. If the adverse effect of the hand brake, it will cause the main clutch, although separated, but still the main clutch shaft due to inertia in rotation (as required, the main clutch in a separate state, the main clutch shaft should stop within 3s), thus shifting time Gear difficult to engage and abnormal noise. In this case, to be adjusted or replaced with a small brake.

Bulldozer is a major mechanical earthmoving machinery, according to the walk is divided into two kinds of crawler and tires, because less tire bulldozer. This paper describes the structure and working principle of Bulldozer. The basic job of a bulldozer excavation is: A. B. earth C. shoveling dump.
Power greater than 120KW crawler dozer, the vast majority use hydraulic - mechanical transmission. Such Hydraulic Drive Crawler Bulldozers from the introduction of Japan's Komatsu D155 type, D85 type, D65 type three basic hydraulic dozer suppliers technology. After localization, stereotyped as TY320 type, TY220 type, TY160 type Basic track bulldozer suppliers.

Background and Significance bulldozer with hydrostatic drive system

Dozer supplier , with the western development and the country's infrastructure accelerated pace for the development of China's construction machinery industry provides a rare opportunity, domestic all manufacturers have expanded product range in their respective fields, the use of some advanced technology to develop their own products or through the introduction of foreign advanced technology to improve product quality. And made some satisfactory achievements. After China's accession to WTO, foreign advanced technology and products of the influx of China's machinery products market project has also caused a serious impact. For this reason countries have proposed a "construction machinery" Tenth Five-Year Development Plan. "

Although since the 1980s, our country through the introduction, digestion and absorption, the traditional mechanical, hydraulic mechanical dozer from the manufacturing capacity, production scale, the basic approach or reach the level of similar foreign products on the technical level. But in recent years with the rapid development of hydraulic integration technology, the traditional mechanical, hydraulic mechanical bulldozer cumbersome operation, labor-intensive, low productivity, system failures and other shortcomings more so it can not meet the production job requirements, development of intelligent construction machinery has become a trend. With the continuous development of science and technology, hydraulic increasingly showing strong vitality, hydraulic drive foreign technology matures, more and more applications in the bulldozers, a great tendency to replace the traditional forms of transmission. Foreign bulldozer hydraulic transmission theory and technology under wraps. The research aspect of the hydraulic transmission as the basis of intelligence bulldozer has just started, the basic theoretical research in the blank.

Hydraulic bulldozer uses hydraulic - mechanical transmission

120KW of power greater than swamp hydraulic track dozer , The vast majority use hydraulic - mechanical transmission. Track Dozer expand the development of product types, both to meet the different conditions of work adaptability, and must be the basic type utmost parts commonality (or interchangeability), which for the majority of users and maintenance bring great convenience.

Hydraulic crawler bulldozer mainly by the engine, transmission, equipment, electrical parts, cab and hood and other components. Among them, the mechanical and hydraulic transmission system also includes a torque converter, the coupling assembly, the planetary gear type power transmission, a central transmission, steering clutches and steering brakes, final drives and travel systems.
Power output mechanism by way of gear and spline connection driven hydraulic system of the working pump, variable speed torque hydraulic system gear pump, hydraulic steering and braking systems steering pump; sprocket representing secondary spur gear final drive mechanism (including left and right final drive assembly); track shoe assembly includes a track, sets the frame and suspension assembly including a walking system.
