Planetary gearbox
The planetary gearbox contains three planetary gear sets, three lockup clutches, four brakes and three freewheels Power from the engine is transmitted through a torque converter to the input shaft of the planetary gearbox. Gear shifting is accomplished by applying a specific combination of brakes and freewheels, which changes the speed of the output shaft.
Elements of the planetary gearbox
1. Lock-up clutch for step-up planetary gear set (WITH0) - connects the carrier and the sun wheel of the step-up row.
2. High row brake (IN0) - stops the sun wheel of the boost row.
3. Clutch No. 1 of the freewheel of the increasing row (F1) - when the brake of the second gear is on, it prohibits the counterclockwise rotation of the sun gears of the front and rear planetary gear sets.
4. Forward clutch (WITH1) - connects the input shaft and the epicycle of the front planetary gear set.
5. Second gear brake (IN2) - stops the outer ring of the freewheel No. 1, thus prohibiting the rotation of the sun gears of the front and rear planetary gears counterclockwise.
6. Brake 1st gear and reverse (IN3) - stops the carrier of the rear planetary gear set.
7. Freewheel No. 2 (F2) - prohibits the rotation of the carrier of the rear planetary gear set counterclockwise. B. Direct clutch (WITH2) - connects the input shaft and the sun gears of the front and rear planetary gear sets.
9. Brake providing engine braking mode in second gear (IN1) - stops the rotation of the sun gears of the front and rear planetary gear sets.
10. Overdrive clutch (F0) - When starting the engine, it connects the sun gear of the boost planetary gear set and the carrier of the boost planetary gear set.
