Abstract

The present disclosure provides a planetary gear train of an automatic transmission for a vehicle to perform ten or more forward speeds and one or more reverse speed. The planetary gear train includes: an input shaft, an output shaft, three planetary gear sets respectively having three rotational elements, and seven control elements for selectively interconnecting the rotational elements and a transmission housing.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0027656 filed on March 8, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to an automatic transmission for a vehicle. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Recently, increases in oil prices have triggered fierce competition to increase fuel consumption of vehicles. [0006] In this sense, studies on engines have been conducted to achieve weight reduction and improvement in fuel consumption through so-called downsizing, and studies on automatic transmissions have been performed to simultaneously provide better drivability and fuel consumption. [0007] In order to obtain more gear stages of an automatic transmission...
