Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0177368 filed on December 10, 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 achieves ten forward speed gears by using a minimum number of constituent elements, thereby improving power transmission performance and reducing fuel consumption. Background technique [0004] Rising oil prices in recent years have fueled a never-ending race to improve fuel efficiency. [0005] As a result, in the case of engines, studies have been conducted to reduce weight and improve fuel efficiency through downsizing, and in the case of automatic transmissions, studies have been conducted to secure bo...
