Torque converter

Torque converter is power separating hydraulic-mechanic type

Transmission assembly

It integrates center drive, transmission and speed changing control valve into one component. It can be assembled or disassembled as assembly or as a part. It is very convenient to service. Transmission is multi-stage planetary drive to realize modular assembling and disassembling. Gear the shift can be changed among 1st gear, 2nd gear, 3rd gear forward or reverse rapidly, through multi-functional control valve.

Steering and braking clutch

Steering and braking clutch are adjustment-free, oil-type, multi-disc clutch. The braking clutch is pressed by spring, separated hydraulically, constant meshed type. Steering clutch is hydraulic pressed, non-constant engaged clutch. Steering and braking acts simultaneously, operated manually to realize steering slowly, sharply and braking. The braking of entire machine can be realized through the pedal. Braking rod is designed to keep the undercarriage system in braking condition and guarantee the machine not to slip on slope when starting the engine.

Final drive

Final drive is two-stage planetary reduction gear mechanism. It is mounted at outside of steering and braking clutch. Combined sprocket segment is very convenient for assembling, disassembling and service.

Undercarriage system

SD8B dozer utilizes elastic-mounted undercarriage. The track is triangle shape. The sprocket is elevated. Through floating function of continuous auxiliary suspension device, the machine can travel near obstacle on the ground to improve traveling stability and comfortable of the driver. Ground contact area is increased. Performance of traveling and traction is raised.

ROPS cabin

The cab is hexagonal thin wall box-type structure. Glass is mounted at six sides with wide viewing range. Pulling and pushing glass is mounted at back side. Air conditioner can be installed according to the requirement of customer. The structure of Rops is rigid. It can protect the driver efficiently when the bulldozer is in special condition. Adjustable operator’s seat bias to right 15° and fuel tank, engine hood, track are tilting, the driver can has a good front and rear sighting range.
