Abstract: Disclosed is a power transmission for a hybrid vehicle which is capable of efficiently controlling energy generated from an engine to get a high degree of efficiency. A power transmission apparatus for a hybrid vehicle comprises an engine, a power splitting part using a planetary gear system, a generating part having two rotors generating electric energy through mutual influences and a motor generating driving force from the electric energy. The power transmission apparatus may reduce an amount of an energy transmitted from the engine to the generating part and also reduce an amount of an energy loss due to converting mechanical energy into electric energy in the generating part.
