Abstract
A power transmission system of a hybrid electric vehicle may include an engine being a power source, a torque transmission device including four rotation shafts and a compound planetary gear set, the torque transmission device converting torque input from the engine, and outputting a converted torque, two supplemental power sources respectively connected to two rotation shafts among the four rotation shafts of the torque transmission device and supplying generated torque to the torque transmission device, two friction members selectively connecting two rotation shafts among the four rotation shafts of the torque transmission device to a transmission housing, an output device outputting torque transmitted from the torque transmission device, and a final reducing device decelerating torque transmitted from the output device and outputting the decelerated torque through a differential apparatus.
