Abstract:
A planetary gear train of an automatic transmission is provided to improve power delivery and fuel efficiency by applying six engagement elements to four planetary gear sets to achieve multiple speeds. The planetary gear train includes: input and output shafts; first to fourth planetary gear sets respectively including first to third rotation elements, fourth to sixth rotation elements, seventh to ninth rotation elements, tenth to twelfth rotation elements; and first to eighth shafts. In particular, the first shaft is fixedly connected to the second and sixth rotation elements, and the input shaft, the fourth shaft is fixedly connected to the fourth and seventh rotation elements, and the seventh and eighth shafts selectively and respectively connect a transmission housing to corresponding rotation elements of the first and third planetary gear sets.

Claim (Index 10):
The planetary gear train of  claim 1 , wherein the first planetary gear set is a single pinion planetary gear set including:\n a first sun gear as the first rotation element, a first planet carrier as the second rotation element, and a first ring gear as the third rotation element, wherein the second planetary gear set is a double pinion planetary gear set including: a second sun gear as the fourth rotation element, a second ring gear as the fifth rotation element, and a second planet carrier as the sixth rotation element, wherein the third planetary gear set is a single pinion planetary gear set including: a third sun gear as the seventh rotation element, a third planet carrier as the eighth rotation element, and a third ring gear as the ninth rotation element, and wherein the fourth planetary gear set is a single pinion planetary gear set including: a fourth sun gear as the tenth rotation element, a fourth planet carrier as the eleventh rotation element, and a fourth ring gear as the twelfth rotation element.
