The present invention relates to a power transmission apparatus which includes a planetary gear set with a planetary carrier of which one side extending to form gear teeth, wherein rotating speed input from a driving power source is reduced and then input to one actuating means, rotating speed of a gear-shifting power source is input to another actuating means to achieve a plurality of gear shifts, generating power is obtained from an output shaft to store electricity to a storage battery, the stored electric energy is utilized as controlling energy for gear-shifting power so that a transmission input shaft can be easily controlled. The power transmission apparatus according to embodiments of the present invention includes an input shaft that has one end constantly connected to a driving power source to receive power from the driving power source, the input shaft having a driving gear fixed mounted thereon, a deceleration unit that is connected to the driving gear and reduces rotating speed of the input shaft, a planetary gear set that includes a first actuating means connected to the deceleration unit and receiving rotating speed of the deceleration unit, a second actuating means receiving power for gear shift, and a third actuating means generating output speed, a gear shift unit that is constantly connected to a gear-shifting power source to receive power for gear shift therefrom, the gear shift unit being coupled with the second actuating means to transfer the power for gear shift thereto; and an output shaft that is fixed to the third actuating means of the planetary gear set to transmit output speed, wherein a rotation axis of the second actuating means is perpendicular to a rotation axis of the deceleration unit, a torque control shaft is connected to the second actuating means to receive rotation force of the second actuating means through a power transferring means, a generator for generating electricity is connected to the torque control shaft, and a storage battery for supplying electricity to the gear-shifting power source is connected to the generator. |
