Pic. 3.73. Planetary Gearbox: 1 - carrier of the increasing planetary gear set; 2 - the epicycle of the increasing planetary series; 3 - intermediate shaft; 4 - epicycle of the posterior planetary gear set; 5 - sun gears of the front and rear planetary gear sets
The planetary gearbox contains three planetary gear sets, three lockup clutches, four brakes and three freewheels. Power from the engine through the torque converter is transmitted to the input shaft of the planetary gearbox. Gear shifting is accomplished by engaging a combination of two controls that changes the output shaft speed.
