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.
