20100133026 | POWER TRAIN OF HYBRID VEHICLE - According to the present invention, since a rotor shaft of a motor can be connected/disconnected with/from an input shaft of a transmission, it is possible to reduce or block vibration and noise between the motor and the transmission, thereby improving durability of the motor and achieving smooth gearshift. Further, when a vehicle is driven with the engine directly connected with the input shaft of the transmission, it is possible to easily implement driving sub-control and regenerative braking control by the motor, thereby achieving good properties against noise and vibration. | 06-03-2010 |
