Abstract

A planetary gear train of an automatic transmission for a vehicle including a first shaft receiving torque of an engine, a second shaft disposed in parallel with the first shaft at a predetermined distance, a first planetary gear set disposed on the first shaft, and including a first rotation element, a second rotation element, and a third rotation element, a second planetary gear set disposed on the second shaft, and including a fourth rotation element connected to the second rotation element through an externally-meshed gear, a fifth rotation element connected to the third rotation element through an externally-meshed gear, and a sixth rotation element selectively connected to the first shaft through two paths including respectively externally-meshed gears, four transfer gears forming the externally-meshed gears, and frictional elements including clutches and a brake.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0129257 filed on Sep. 26, 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 for an automatic transmission of a vehicle, which improves mountability and power transmission performance, and reduces fuel consumption. Background technique [0004] In general, a multi-speed mechanism of an automatic transmission can be realized by combining a plurality of planetary gear sets and a plurality of friction elements. [0005] It is known that when a planetary gear train achieves a greater number of shift speeds, the speed ratio of the planetary gear train can be more optimally designed, and thus the vehicle can have economical fuel mileage and...
