Power Flow In Reverse

Power Flow in Reverse Gear: The drive clutch B is closed in reverse gear. As a result, the sun gear 2 (3) in the double planetary gear train is driven while being in mesh with the long planet gears. The double planet carrier is supported by brake clutch D and the gearbox housing. The internal gear 2 (output shaft) can now be driven by the long planet gears in the opposite direction of engine rotation (large gear reduction).
