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 1):
A planetary gear train of an automatic transmission for a vehicle, the planetary gear train comprising:\n an input shaft configured to receive a torque from an engine; an output shaft configured to output a torque; a first planetary gear set including first, second, and third rotation elements; a second planetary gear set including fourth, fifth, and sixth rotation elements; a third planetary gear set including seventh, eighth, and ninth rotation elements; a fourth planetary gear set including tenth, eleventh, and twelfth rotation elements; a first shaft fixedly connected to the second rotation element and the sixth rotation element, and fixedly connected to the input shaft; a second shaft fixedly connected to the eighth rotation element and fixedly connected to the output shaft; a third shaft fixedly connected to the third rotation element; a fourth shaft fixedly connected to the fourth rotation element and the seventh rotation element; a fifth shaft fixedly connected to the fifth rotation element; a sixth shaft fixedly connected to the twelfth rotation element; a seventh shaft fixedly connected to the first rotation element and selectively connected to a transmission housing; and an eighth shaft fixedly connected to the ninth rotation element and selectively connected to the transmission housing, wherein the third shaft is selectively connected to the fourth shaft, the third shaft is selectively connected to the fifth shaft, the third shaft is selectively connected to the eighth shaft, and the sixth shaft is selectively connected to the second shaft.
