(3) 4WD / Bi-speed Turn Oil Flow
Oil pressure-fed from the power steering hydraulic
pump is flowed to the solenoid valve assembly (7)
through the steering controller and oil cooler. The
system hydraulic pressure-fed to disengaged position for
2WD-4WD clutch (4) when 4WD / Bi-speed turn switch
at 2WD position. As the 4WD (1) or Bi-speed turn (3) the
solenoid valve is electrified, the oil flow is switched and
either Bi-speed turn clutch or 4WD clutch is engaged.
When the Bi-speed turn solenoid valve (3) shift to
Bi-speed turn side, the 4WD priority valve (2) effect to
reduce the engagement shock of clutch pack.
The maximum pressure against the clutch piston is
regulated under approx. 2.45 MPa (25.0 kgf/cm
2
,
356 psi) by the relief valve of PTO clutch valve. And a
part of oil is used for lubricating 4WD clutch pack through
the orifice (6).
On the other hand, the return oil is flowed to the
transmission case through the solenoid valve assembly
(7).
