SYSTEMS OPERATION
Direct Power Shift (DPS)
Power from diesel engine 1 is sent through damper
2 to universal joint 3. The universal joint drives
the sun gears andplanet gears in the transmission.
Five planetary gear trains 4, each with its own
clutch, give the machine three speeds in either
forward or reverse. The selection of the desired
machine speed is done manually by the operator
but hydraulic oil, directed by the transmission
hydraulic control valve, engages the clutches in
the transmission.
The output shaft of the transmission drives the
input shaft of transfer 5. The bevel pinion in the
transfer sends power to bevel gear 6. The power
is then sent through steering clutches 7 into final
drives 8, to the sprockets which drive the tracks.
~ The engine and damper are integrally coupled
and are mounted on the frame at four places with
cylindrical rubber mounts.
The transmission planetary gears and transfer
are housed in their own cases. The transfer case
is bolted to the front of the steering clutch cases.
