Abstract

In a planetary gear type transmission system for seven forward speeds and one rearward speed, a high speed stage gear train is disposed on an input side of a low speed stage gear train, a low speed use rotary clutch in the low speed stage gear train is constructed so as to directly couple a ring gear in the high speed stage gear train with a carrier in the high speed stage gear train, a first speed stage gear train is disposed on an output side of a second speed stage gear train, a carrier in the first speed stage gear train is coupled to an output shaft, and a fourth speed stage gear train, a third speed stage gear train and a reverse stage gear train are disposed between the low speed stage gear train and the second speed stage gear train.
