Abstract

The invention relates to a planetary gear train of an automatic transmission for a vehicle. The planetary gear train may include an input shaft receiving torque of an engine, an output shaft outputting changed torque, a first planetary gear set, a second planetary gear set, a third planetary gear set, a fourth planetary gear set, a first rotation shaft selectively connected to a transmission housing, a second rotation shaft, a third rotation shaft selectively connected to the transmission housing, a fourth rotation shaft directly connected to the input shaft, a fifth rotation shaft, a sixth rotation shaft, a seventh rotation shaft selectively connected to the input shaft, and selectively connected to the fifth rotation shaft or the sixth rotation shaft, and an eighth rotation shaft directly connected to the output shaft.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0178383 filed on December 11, 2014, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an automatic transmission for a vehicle. More particularly, the present invention relates to a planetary gear train of an automatic transmission for a vehicle, which improves power transmission performance and reduces fuel consumption by realizing ten forward gears using a minimum number of constituent elements. Background technique [0004] In recent years, rising gas prices have forced vehicle manufacturers into an extreme race to improve fuel efficiency. [0005] As a result, studies on reduction in weight and improvement in fuel efficiency through downsizing have been conducted in the case of engines, and studies in ensuring both operability and competitiveness in ...
