Abstract

A planetary gear train of an automatic transmission for a vehicle may include: a first shaft; a second parallel shaft; a first planetary gear set on the first shaft including a first element selectively connected to the first shaft, a second element selectively connected to the first shaft or a transmission housing, and a third output element; a second planetary gear set on the second shaft, and including a fourth element selectively connected to the first shaft, connected to the first element, and selectively connected to the transmission housing, a fifth element connected to the third element and directly connected to an output gear, and a sixth element selectively connected to the first shaft; four transfer gears; and frictional elements including clutches selectively connecting the first, second, fourth, and sixth elements with the first shaft and brakes selectively connecting the second and fourth elements with the transmission housing.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2013-0136460 filed on Nov. 28, 2012, 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 can improve mounting performance and power transmission performance and reduce fuel consumption. Background technique [0004] Generally, a planetary gear train is realized by combining a plurality of planetary gear sets and friction members. It is well known that when the number of shift speeds achieved by a planetary gear train is greater, the speed ratio of the planetary gear train can be more optimally designed, and thus the vehicle can have economical fuel mileage and better performance. For this reason,...
