FOUR WHEEL DRIVE CONTROL SYSTEM


  1. CONSTRUCTION


    1. A transfer low planetary gear assembly is used on the planetary gear unit to switch the transfer gear ratio between high and low.

    2. The transfer low planetary gear assembly consists of the planetary sun gear, 4 planetary pinion gears, planetary ring gear, and planetary carrier.

    3. The planetary sun gear is integrated with the transfer input shaft. A transfer clutch hub spline piece is fitted to the rear of the planetary sun gear.

    4. 4 planetary pinion gears are fitted to the planetary carrier. Each pinion gear shaft is fixed to the planetary carrier. A transfer low planetary spline piece is fitted to the rear of the planetary carrier.

    5. The planetary ring gear is fixed to the front transfer case and its internal teeth mesh with the planetary pinion gears.

    6. In this planetary gear unit, the power transmission route is switched in accordance with the movement of the transfer high and low clutch sleeve. The input power from the transfer input shaft is transmitted to the center differential case via the transfer high and low clutch sleeve.
