Abstract

A multi-stages automatic transmission for vehicle may include first, second, third and fourth planetary gear sets each including first, second and third rotation elements, friction members including first, second, third and fourth clutches and first and second brakes, in which an input shaft may be connected to the first rotation element of the second planetary gear set and the third rotation element of the fourth planetary gear set, and an output shaft may be connected to the second rotation element of the fourth planetary gear set. According to the invention, eleven forward speeds and one reverse speed can be realized, the operating point of an engine is in a low RPM range, so that the drive ability of a vehicle can be greatly improved, the multi-stages effect of the automatic transmission can make the engine be driven at a best point, so that the fuel efficiency can be improved.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2014-0151973 filed on Nov. 4, 2014, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] Various embodiments of the present invention relate to an automatic transmission for a vehicle, and more particularly to a multi-gear automatic transmission for a vehicle equipped with a transmission mechanism, capable of realizing eleven forward speeds and One reverses and drives the engine at its sweet spot. Background technique [0004] At present, technological developments require performance improvements, and a similar situation occurs in the field of power trains. Due to the strengthening of environmental regulations or rising oil prices, people have put forward more demands for fuel efficiency improvements. [0005] As suitable powertrain technologies that meet these demands, there are engine downsizing...
