The development and expansion of crawler bulldozer products must not only meet the work adaptability of different working conditions, but also maintain the maximum commonality (or interchangeability) of parts and components with the basic model. This brings maintenance to the majority of users. Great convenience. In order to facilitate the purchase of accessories, the manufacturers have retained the part numbers of Komatsu Company of Japan, and only the parts designed by themselves in the modification are named by their own manufacturers.
Crawler-type crawler bulldozers are 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 brake, final drive and walking system. The power output mechanism drives the working pump, the variable-speed torque-converting hydraulic system, and the steering pump of the steering brake hydraulic system in the hydraulic system of the working device by means of gear transmission and spline connection; the sprocket represents the final drive mechanism of the secondary spur gear transmission (Including the left and right final drive assemblies); the track shoe includes the walking system including the track assembly, the trolley frame and the suspension assembly.
