ND
GEAR
Since N
i
> n
i
, the output rpm is slowed in relation to the input rpm.
Since the rotation of the sun gear was reverse in 1st gear, the front carrier was slowed to that extent, but in 2nd gear the
sun gear is fixed, so the slowing of the front gear is less than that in 1st gear. Accordingly, the output rpm is higher than in
1st gear.

GEAR
Since the output rpm of the front internal gear and the sun gear are the same, the front planetary unit rotates at one
body so that N
i
= N
c
, and the output shaft and input shaft are in a state direct connection.
