POWER TRANSMISSION APPARATUS FOR HYBRID ELECTRIC VEHICLE

摘要

A power transmitting apparatus may include a first input shaft to selectively receive torque of an engine, a second input shaft having at least one input gear fixedly disposed thereon, a third input shaft having at least one input gear fixedly disposed thereon, a motor/generator operated as a motor or a generator, a planetary gear set including a first rotation element directly connected to the motor/generator, a second rotation element directly connected to the third input shaft, and a third rotation element directly connected to the first input shaft, a first speed output unit to convert toque input from the second input shaft or the third input shaft and output the converted torque, and a second speed output unit to convert torque input from the second input shaft or the third input shaft and output the converted torque.

1. A power transmitting apparatus for a vehicle comprising:
a first input shaft adapted to selectively receive torque of an engine; a second input shaft disposed without rotational interference with the first input shaft, adapted to selectively receive the torque of the engine, and having at least one input gear fixedly disposed thereon; a third input shaft disposed in a row with the second input shaft and without rotational interference with the first input shaft, and having at least one input gear fixedly disposed thereon; a motor/generator operated as a motor or a generator; a planetary gear set including a first rotation element directly connected to the motor/generator, a second rotation element directly connected to the third input shaft, and a third rotation element directly connected to the first input shaft; a first speed output unit adapted to convert toque input from the second input shaft or the third input shaft and output a converted torque; and a second speed output unit adapted to convert torque input from the second input shaft or the third input shaft and output a converted torque.
