POWER TRANSMISSION APPARATUS FOR HYBRID ELECTRIC VEHICLE

摘要

A power transmission apparatus for a may include 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, a third input shaft disposed in a row with the second input shaft and without rotational interference with the first input shaft, a planetary gear set including a first rotation element, a second rotation element directly connected to the third input shaft, and a third rotation element directly connected to the first input shaft, a motor/generator directly connected to the first rotation element, and a first speed output unit and a second speed output unit each adapted to convert torque input from the second input shaft or the third input shaft and output the converted torque.

1. A power transmission 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, selectively connected to the first input shaft, 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 planetary gear set including a first rotation element, a second rotation element directly connected to the third input shaft, and a third rotation element directly connected to the first input shaft; a motor/generator directly connected to the first rotation element and operated as a motor or a generator; a first speed output unit adapted to convert torque input from the second input shaft or the third input shaft and output the 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 the converted torque.
