Center Differential Control Clutch

CENTER DIFFERENTIAL CONTROL CLUTCH
- The center differential control clutch operates the piston by hydraulic pressure so that the clutch plates and clutch discs are pressed together. The friction resistance thus created transmits the torque and operation of the center differential is controlled.
- Because the clutch plates and clutch discs are interlocked with the spline of the ring gear mounting case and front differential case respectively, both cases try to rotate as a unit in response to the friction force from the contact of the clutch plates and discs. In the way, operation of the center differential is restrained and the power to control the difference between the rotation of the front and rear shafts produced.
- The hydraulic pressure operating on the piston is adjusted according to the throttle valve opening angle and the shift position.




Hydraulic Pressure Control System
The hydraulic pressure operating on the center differential control clutch is adjusted by the No.2 pressure regulator valve to a pressure corresponding to the throttle valve opening angle and the shift position. By operating the solenoid valve the clutch control valve opens and closes the fluid passages to the piston, and regulates the operation or non-operation of the center differential control clutch.
