(Continued)
Signals are sent from the Hi-Lo change lever switch to the ECU. Then the signals are sent from the ECU to the
Hi-Lo change valve. Then the Hi-Lo solenoid valve is opened. As a result, the position of the two-speed change spool
is changed with charge oil to the position shown in the drawing. In this state, oil between
"A"
and
"C"
(Forward and
high pressure side) is guided through the two-speed change spool to the pistons on the Hi side, and the angle of the
swashplate on the motor side is changed as shown in the drawing (the inclination angle becomes smaller). As a result,
the revolving speed of the motor shaft is increased.
* When the angle of the swashplate on the motor side is changed, the swashplate on the pump side goes back
slightly toward the neutral position to achieve smooth shift transmission when speed is changed (from Lo to Hi). After
the angle of the swashplate on the motor side is changed, the swashplate on the pump side gradually returns to its
original position.
