ABSTRACT:
A planetary gear transmission comprises first, second and third planetary gear trains G1, G2 and G3 which are disposed coaxially with one another and respectively in this order from an input member. The first and second ring gears R1 and R2, which are fixedly retainable by a first brake B1, are disengageably connected to the input shaft 1 through a first clutch K1. The first sun gear S1 is also disengageably connected to the input shaft 1 through a third clutch while the first carrier C1 and the second sun gear S2 are connected to the output shaft 7. Furthermore, a connecting shaft 4 is disposed away from and in parallel with the axis of the first, second and third planetary gear trains G1, G2 and G3, and one end of the connecting shaft is connected to the input shaft 1 through a first connecting gear train 2 and 3 while the other end of the connecting shaft is connected to the third sun gear S3 through a second connecting gear train 5 and 6.
