摘要： A transmission for a vehicle capable is provided to improve fuel efficiency through multiple gear shift stages and enhance power performance of an engine. By combining first and second planetary gear sets, a compound planetary gear set, and multiple frictional elements selectively connecting rotary components of the three planetary gear sets via a corresponding shaft, the transmission provides eleven forward gear stages and three reverse gear stages. In particular, a first rotary element of the first planetary gear is fixedly connected to a transmission case, a second rotary element of the first planetary gear is fixedly connected to a second rotary element of the second planetary gear, and a third rotary element of the first planetary gear device is selectively connected to a first rotary element of the compound planetary gear set and a fourth rotary element of the compound planetary gear set.

摘要： The present disclosure provides a planetary gear train of an automatic transmission for a vehicle having advantages of improving power transfer performance and fuel efficiency by implementing ten forward speeds and one reverse speed. The planetary gear train includes: first, second, third, and fourth planetary gear sets; an input shaft; an output shaft; eight shafts connected to the respective rotation elements of the first, second, third, and fourth planetary gear sets; four clutches and two brakes which are control elements; and a transmission housing H. With this arrangement, rotation power from an engine which is input from the input shaft is shifted by a mutual complementing operation between the first, second, third, and fourth planetary gear sets, and is then output through the output shaft.
