Power Flow In Fifth and Sixth Gear

Power Flow in 5th Gear: Drive clutches B and E are engaged in 5th gear. The sun gear 2 (3) in the double planetary gear train is driven by clutch B and the planet carrier of the double planetary gear train by clutch E. Together with the double planet carrier, the long planet gears and the short planet gears drive the internal gear 2 in the direction of engine rotation. This results in a gear ratio with a slight overdrive.




Power Flow in 6th Gear: In 6th gear, the sun gear 2 in the double planetary gear train is blocked by clutch C. The planet carrier is driven by the engaged clutch E. As a result, the long planet gears are forced to move by rolling contact (reaction) on the fixed sun gear 2 (3) and drive the internal gear in the direction of engine rotation. This results in a large gear ratio in overdrive. The single gear train is not operative in 6th gear.
