Fourth Gear

Fourth Gear





Gear rotation speed





^ Suppose the gear ratio in fourth gear is i4,

i4= NC/NR

^ From the result of NS=0 in formula (2), the relation between the gear ratio in fourth gear and the rotation speed of the front planetary gear set is indicated in the formula below.
(ZRF+ZSF) NC=ZRFNR

^ Therefore,





^ As a result, the gear ratio in fourth gear is 0.694.
