(2) Reverse (3.385)
Middle planetary gear locked, middle sun gear rotated
When the sun gear rotates with the planetary gear locked in middle planetary gear set, the annulus
gear (front planetary gear) rotates in reverse direction with decreased speed and the power flows
through the front planetary gear.
The rear planetary gear set reduces the rotating speed of rear & front annulus gears and the front
planetary gear set rotates the front sun gear in reverse direction without load. -

(3) 1st Drive Gear (4.212)
Front sun gear and middle & rear planetary gears locked, and rear sun gear always rotated
When the rear sun gear rotates, the rear planetary gear set reduces the speed at first, and then the
reduced power is transferred to rear & front annulus gear. The power is secondarily reduced at front
planetary gear locked with sun gear and flows to front planetary gear.
At this moment, the middle sun gear rotates in reverse direction without load (idling) by the rotation of
middle annulus gear integrated with front planetary gear. -

(4) 2nd Drive Gear (2.637)
Front sun gear and middle sun gear locked, rear sun gear always rotated
When the sun gear rotates, the power is transferred to the rear & front annulus gears, and then the
reaction power from the front planetary gear and middle annulus gear locked with sun gear is
transferred to middle & rear planetary gear to circulate the power. Accordingly, the power flows
through the front planetary gear while keeping the balance. -

(5) 3rd Drive Gear (1.800)
Front sun gear locked, middle & rear sun gear rotated
When the middle sun gear and rear sun gear rotate, the power is transferred to the rear & front
annulus gears, and then the reaction power from the front planetary gear and middle annulus gear
locked with sun gear is transferred to middle & rear planetary gear to circulate the power.
Accordingly, the power flows through the front planetary gear while keeping the balance. -

(6) 4th Drive Gear (1.386)
Front sun gear locked, rear planetary gear and rear sun gear rotated
When the overdrive clutch (OD/C) operates, the carrier is engaged with sun gear in rear planetary
gear set and the power with 1:1 ratio flows to the front planetary gear locked with sun gear after
passing through the rear & front annulus gears.
At this moment, by operation of speed-reduced annulus gears and carrier in 1:1 ratio, the middle sun
gear in middle planetary gear set increases its speed without load (idling). -

(7) 5th Drive Gear (1.000)
Middle & rear planetary gears, middle sun gear and rear sun gear rotated
The rotating ratio of 1;1 is transferred to middle annulus gear (front planetary gear) because the
middle planetary gear and sun gear in middle planetary gear set rotate simultaneously.
At this moment, the rear planetary gear set rotates in 1:1 ratio (same in 4th gear). However, the front
planetary gear set is not related to that, and the front sun gear rotates without load (idling) in 1:1 ratio. -

Middle planetary gear rotated, middle sun gear locked
When the sun gear is locked in middle planetary gear set and the planetary gear rotates, the middle
annulus gear increases the speed and the power is transferred to front planetary gear.
The rear planetary gear set rotates in 1;1 ratio (same in 4th & 5th gears). However, the front
planetary gear set is not related to that, and the front sun gear increases its speed without load
(idling). -
