Outline
• The motive force from engine (17) passes
through the flywheel and is transmitted to torque
converter (18).
The torque converter uses oil as a medium. It
converts the transmitted torque in accordance
with the change in the load, and transmits the
motive force to the input shaft of the transmission.
In addition, the motive force of the engine passes
through the pump drive gear of the torque converter,
and is transmitted to hydraulic, steering
switch, PPC Pump (19) and torque converter
charging pump (20) to drive each pump.
• Transmission (10) operates the directional spool
and speed spool of the transmission valve through
the solenoid valves, and actuates the six hydraulically
actuated clutches to select one of the
four FORWARD or REVERSE speeds.
The transmission speed range is selected manually.
• The output shaft of transmission (10) transmits
the power to the front and rear axles.
At the front, the power is transmitted to front
axle (5) through center drive shaft (8), flange
bearing (7), and front drive shaft (6).
At the rear, the power is transmitted to rear axle
(15) through rear drive shaft (11).
• The motive force transmitted to front axle (5)
and rear axle (15) has its speed reduced by the
bevel gear and pinion gear of differentials (4)
and (14), and is then transmitted to the sun
gear shaft through the differential mechanism.
• The motive force of the sun gear is rduced
further by the planetary mechanism and is transmitted
to the wheels through the axle
