Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0177364 filed on December 10, 2014, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present application relates to an automatic transmission for a vehicle. More particularly, the present application relates to a planetary gear train of an automatic transmission for a vehicle, which improves power transmission performance and reduces fuel consumption by implementing ten forward gears using a minimum number of constituent elements. Background technique [0004] Rising gas prices in recent years have forced automakers into 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 en...
