Abstract

A power transmission apparatus for a vehicle is provided. The power transmission apparatus includes: an input shaft, an output gear; a compound planetary gear set including a first planetary gear setincluding first, second and third rotation elements, and a second planetary gear set including fourth, fifth and sixth rotation elements; a first shaft fixedly connected with the first rotation element and the fourth rotation element and selectively connected with the input shaft; a second shaft fixedly connected with the fifth rotation element, and selectively connected with the input shaft and atransmission housing; a third shaft fixedly connected with the second rotation element, the sixth rotation element and the output gear; a fourth shaft fixedly connected with the third rotation element; an intermediate shaft; a first gear set transmitting the torque from the input shaft to the intermediate shaft; and a second gear set selectively transmitting the torque from the intermediate shaftto the fourth shaft.

Description

[0001] Cross references to related applications [0002] This application claims the priority and rights of Korean Patent Application No. 10-2018-0098123 filed on August 22, 2018, the entire content of which is incorporated herein by reference. Technical field [0003] The present invention relates to a power transmission device for a vehicle. Background technique [0004] The statements in this section only provide background information related to the present invention and do not constitute prior art. [0005] In order to achieve increased fuel consumption and better drivability, research has been conducted to achieve more gears of automatic transmissions, and recently, the increase in fuel prices has triggered fierce competition to increase vehicle fuel consumption. [0006] In this sense, research has been conducted on the engine to achieve weight reduction and increase fuel consumption through so-called downsizing, and the automatic transmission has been developed to provide both ...
