<p>PURPOSE: A powertrain for an eco-friendly car is provided to improve fuel and drive efficiency by directly connecting a starter motor to an engine and simultaneously driving two motors in the drive mode of an electric motor. CONSTITUTION: A powertrain for an eco-friendly car comprises an engine(10), a first motor(20), a second motor(30), a gear box(40), a clutch(50), a damping device(60), and a differential gear(70). The first motor is arranged on the engine and coaxial. The rotor of the first motor is fixedly connected to the output shaft of the engine. The second motor is arranged on the engine and coaxial. The rotor of the second motor is fixedly connected to the input shaft of the gear box. The clutch is interposed between the first and second motors and selectively connects the first and second motors. The damping device is interposed between the first motor and clutch and is connected to the rotor of the first motor. The differential gear is connected to the output shaft of the gear box and is equipped with a plurality of friction members and one or more streamlined gear sets.</p> |
