Problems solved by technology

[0010] Therefore, in order to increase the number of gears of the automatic transmission, a double-row structure in which a planetary gear set is arranged on a planetary gear set has recently been adopted, or a claw clutch has been recently applied instead of a wet control element, but for this, we have found that there is a possibility Problems with structural limitations of the application and poor shift sensitivity due to the application of dog clutches

Abstract

The present invention discloses a planetary gear train for an automatic transmission of a vehicle, which has the benefit of improving power transmission performance and fuel economy by realizing at least ten forward gears and one reverse gear. The planetary gear train may include: a first planetary gear set, a second planetary gear set, a third planetary gear set and a fourth planetary gear set arranged on the same axis; an input shaft; an output shaft; connected to the first planetary gear set , eight rotation shafts of at least one of the rotation elements of the second planetary gear set, the third planetary gear set, and the fourth planetary gear set; four clutches and two brakes as control elements; and a transmission case. The torque input from the input shaft is changed through cooperation of the first planetary gear set, the second planetary gear set, the third planetary gear set and the fourth planetary gear set, and the changed torque is output through the output shaft.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0117357 filed September 12, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an automatic transmission for a vehicle. More particularly, the present invention relates to a planetary gear train of an automatic transmission for a vehicle, which improves power transmission performance and fuel economy. Background technique [0004] The statements in this section merely provide background information related to the present invention and may not constitute prior art. [0005] In summary, automatic transmissions implementing more gears have been developed to enhance fuel economy and optimize drivability. The recent rise in oil prices has triggered intense competition to improve vehicle fuel consumption. [0006] Therefore, many studies have been conducted...
