Torque converter

Power separating, hydraulic-mechanic drive, single stage torque converter is used in SD8 elevale sprocket bulldozer.

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

Steering and braking clutch are adjustment-free, oil-type, multi-disc clutch. The braking clutch is pressed by spring, separated hydraulicly, 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

SD8 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 travelling stability and comfortable of the driver. Ground contact area is increased. Performance of travelling and traction is raised.

Implement hydraulic system

Implement hydraulic system can control lifting, lowering and tilting of the blade. It also can control the moving of ripper. It mainly consists of oil pump, cylinder, valve group, oil tank line and controlling parts. Implement pump is two group vane type pump.
