<p>PROBLEM TO BE SOLVED: To provide a power transmission device for hybrid electric vehicle eliminating the need for configuring a complicated hydraulic circuit, capable of reducing an entire weight with a simple structure, and providing a high energy efficiency and an excellent acceleration performance at the time of departure and at low speeds. SOLUTION: This power transmission device comprises a first motor used also as a generator connected to a battery for hybrid electric vehicle through an inverter a differential gear part interposed between an engine for hybrid electric vehicle and the first motor and selectively receiving a drive force from the internal combustion engine and the first motor, a decelerating driven gear meshed with the differential gear part to transmit a power to wheels, a second motor connected to the battery through the inverter and directly driving an axle, a first one-way clutch interposed between the differential gear part and the internal combustion engine, and a second one-way clutch installed in the differential gear part.</p> |
