DESCRIPTION OF CONSTRUCTION AND OPERATION


FREEWHEEL MECHANISM




  • This device is composed of main shaft, clutch sleeve, clutch gear, shift rod, and shift fork, etc.
  • The freewheel clutch assembly is electrically and automatically controlled utilizing an ON/OFF signal from the 4WD detection switch which is located in the transfer.
  • The solenoid valves are either activated or deactivated to change the passage of vacuum to the actuator according to the ON/OFF signal. Operated by the actuator, via the shift rod and shift fork, the clutch sleeve slides to either 2WD or 4WD position to select the drive train mode.
  • A vacuum tank is incorporated to provide a better freewheel clutch operation.
