- Commodity name: Bulldozer 5
Bulldozer is one of the main machinery of earthmoving engineering, which can be divided into crawler type and wheel type according to the walking mode. Because there are fewer wheel bulldozers. This paper mainly describes the structure and working principle of crawler bulldozer. The basic work of bulldozer excavation is: shovel soil, transport soil, unload soil.
Bulldozer is one of the main machinery of earthmoving engineering, which can be divided into crawler type and wheel type according to the walking mode. Because there are fewer wheel bulldozers. This paper mainly describes the structure and working principle of crawler bulldozer. The basic work of bulldozer excavation is: shovel soil, transport soil, unload soil.
The vast majority of crawler bulldozers with power greater than 120KW adopt hydraulic - mechanical transmission. The bulldozer is based on three basic bulldozer manufacturing technologies, D155, D85 and D65, adopted by Komatsu Manufacturing. After localization, it is shaped as TY320, TY220, TY160 basic bulldozer. In order to meet the needs of users in various working conditions, Chinese bulldozer manufacturers have expanded product varieties on the basis of the above three basic types of bulldozer, and formed three series of bulldozer. TY220 bulldozer series products, including TSY220 wetland bulldozer, TMY220 desert bulldozer, TYG220 plateau bulldozer, TY220F forest logging bulldozer, TSY220H environmental protection bulldozer and DG45 pipe crane, etc. A similar series of TY320 and TY160 bulldozers is also being expanded. TY160 series also includes TSY160L super wetland bulldozer and TBY160 brazing machine.
The development and expansion of bulldozer products, not only to meet the adaptability of different working conditions, but also must maintain the maximum versatility of parts (or interchangeability) with the basic type, which brings great convenience for the majority of users to use and maintain. In order to facilitate users to purchase parts, the manufacturer retains the parts number of Komatsu Company in Japan, and only the parts designed by itself in the modification are labeled with the manufacturer's number.
Part of a bulldozer
Partial Structure of Bulldozer (4 sheets)
Crawler bulldozer is mainly composed of engine, transmission system, working device, electrical part, cab and hood. Among them, the mechanical and hydraulic transmission system includes hydraulic torque converter, coupling assembly, planetary gear type power shift transmission, central transmission, steering clutch and steering brake, final transmission and walking system.
The power output mechanism drives the working pump in the hydraulic system of the working device, the variable speed and variable torque hydraulic system, and the steering pump in the steering brake hydraulic system by the way of gear transmission and spline connection. The sprocket represents the final drive mechanism of the two-stage spur gear drive (including the left and right final drive assembly); The track plate comprises the track assembly, the frame and the suspension assembly of the walking system.Key words:- Bulldozer 5
