PURPOSE: A vehicle transmission system including two planetary gears is provided to shift a gear according to whether a sub motor is operated or not, thereby reducing the power consumption. CONSTITUTION: A connection gear connects a main motor with a sub motor. The connection gear includes a planetary gear, a worm wheel (340) connected to the planetary gear and a worm gear (350). The planetary gear includes a first line gear (310), a first planetary gear (331), a second planetary gear (332), a carrier (333) and a second line gear (320). The carrier is connected to the first planetary gear and the second planetary gear. The first planetary gear and the second planetary gear are connected through a shaft coupling member (360). The shaft coupling member includes a ring member, a taper member and a bolt which is engaged with the ring member and the taper member. |
