Abstract

Ten forward speeds and one or more reverse speed are achieved by a planetary gear train of an automatic transmission for a vehicle including an input shaft, an output shaft, four planetary gear sets respectively having three rotational elements, and six 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. 10-2016-0132413 filed with the Korean Intellectual Property Office on October 12, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present embodiment relates to a planetary gear train of an automatic transmission for a vehicle. Background technique [0004] In the field of automatic transmissions, more gears are a useful technique for improving fuel consumption and drivability of vehicles. Recently, the increase in oil price is causing fierce competition in improving the fuel consumption of vehicles. [0005] In this sense, research on engines has been conducted to achieve weight reduction and improve fuel consumption through downsizing, and research on automatic transmissions has been conducted to simultaneously provide better drivability and fuel consumption. [0006] In order to ach...
