Abstract
A power transmission system of a hybrid electric vehicle may include, a generating device adapted to generate electricity by torque of an engine or to start the engine. an input device adapted to receive the torque of the engine. a speed output device changing the torque transmitted from the input device into two speed steps and outputting the changed torque. an auxiliary power source disposed between the input device and the speed output device and adapted to supply torque to the speed output device or to generate electricity by the torque of the speed output device. a final reduction device outputting the torque transmitted from the speed output device.
