Abstract

A planetary gear train of an automatic transmission for a vehicle may include an input shaft for receiving an engine torque, an output shaft for outputting a shifted torque, a first planetary gear set, a second planetary gear set, a third planetary gear set, a fourth planetary gear set, a first shaft, a second shaft directly connected with the input shaft, a third shaft, a fourth shaft, a fifth shaft selectively connectable with the first shaft, a sixth shaft selectively connectable with the fourth shaft, a seventh shaft selectively connectable with the fourth shaft, and an eighth shaft selectively connectable with the fifth shaft and directly connected with the output shaft.

Description

technical field [0001] The present invention relates to automatic transmissions for vehicles. More particularly, the present invention relates to a planetary gear train of an automatic transmission for a vehicle, which has the advantage of realizing at least ten forward speeds with a minimum of structures, thereby being able to utilize multiple gears to enhance power transmission performance and improve fuel consumption, And the driving stability is improved by using the driving point in the low speed range of the engine. Background technique [0002] In general, in the field of automatic transmissions, achieving more shift gears is a technique that has been under research for maximizing fuel consumption and driving efficiency, and recent increases in oil prices have caused rigid competition to increase fuel consumption of vehicles. [0003] In this sense, research has been done on engines to achieve weight reduction and increase fuel consumption through so-called downsizin...
