Embodiment Construction

[0024] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0025] In the following description, dividing the names of components into first, second, etc. is for dividing the names because the names of the components are the same as each other, and the order thereof is not particularly limited.

[0026] figure 1 is a schematic diagram of a planetary gear train according to an exemplary form of the present disclosure.

[0027] refer to figure 1 , the planetary gear train includes: the first planetary gear set PG1, the second planetary gear set PG2, the third planetary gear set PG3 and the fourth planetary gear set PG4 arranged on the same axis; the input shaft IS; the output shaft OS; Seven shafts TM1 to TM7 interconnected by rotation elements of a planetary gear set PG...

Abstract

Nine or more forward speeds and one or more reverse speeds are achieved through a planetary gear train for an automatic transmission of a vehicle. The planetary gear train includes: an input shaft; an output shaft; four planetary gear sets; and six control assemblies. Specifically, each of the four planetary gear sets includes a sun gear, a planet carrier and a ring gear. Selective connections between the sun gear, planet carrier, ring gear, and transmission housing are performed by six control assemblies.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0027655 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] Research on realizing more shift stages (gear stages) of automatic transmissions has been conducted to achieve improvement in fuel consumption as well as improvement in drivability, and recently, increases in oil prices have sparked fierce competition to improve fuel consumption of vehicles. [0006] In this regard, studies on engines have been conducted to achieve weight reduction and improve fuel consumption through so-called downsizing, and studies on automatic...
