Embodiment Construction

[0044] 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.

[0045] As those skilled in the art would realize, the described form may be modified in various different ways, all without departing from the spirit or scope of the present disclosure.

[0046] 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 their order is not particularly limited.

[0047] figure 1 is a schematic diagram of a planetary gear train according to a first exemplary form of the present disclosure.

[0048] refer to figure 1 , the planetary gear train includes: input shaft IS; output shaft OS; first planetary gear set PG1, second planetary gear set PG2 and third plane...

Abstract

In the invention, ten or more forward speeds and two or more reverse speed are achieved by a planetary gear train of an automatic transmission that includes three planetary gear sets mounted on an input shaft, an output shaft disposed in parallel with the input shaft and having an output gear. The transmission further includes six shafts respectively interconnecting corresponding elements among the input shaft and rotational elements of the three planetary gear sets, a first transfer gear selectively delivering torque between one of the six shafts and the output shaft; and a second transfer gear selectively delivering torque between the output shaft and one rotational element of the third planetary gear set.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0170770 filed on December 14, 2016, which is hereby incorporated by reference in its entirety. 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, rising oil prices have created fierce competition in optimizing the fuel consumption of vehicles. [0006] In this sense, automatic transmissions have been researched to simultaneously provide better drivability and fuel consumption by implementing more gears. [0007] To achieve more gears for an automatic transmission, the number of parts is typically increased, which may result in degraded installability, production cost, weight, and / or power flow effici...
