Abstract:
A planetary gear train of an automatic transmission may include input and output shafts, first to fourth planetary gear sets respectively having first to third, fourth to sixth, seventh to ninth, and tenth to twelfth elements, a first shaft fixed with the input shaft, the third element, and the fifth element, a second shaft fixed with the ninth and eleventh elements, and selectively connectable to the input shaft, a third shaft fixed with the eighth and twelfth elements, and the output shaft, a fourth shaft fixed with the first element, a fifth shaft fixed with the second and sixth elements, a sixth shaft fixed with the tenth element, and a plurality of shafts, each of which is selectively connectable to a housing and fixed to an element of the first and second gear sets which is not fixed with any of the first to sixth shafts.

Claim (Index 1):
A planetary gear train apparatus of an automatic transmission for a vehicle, the apparatus comprising:\n an input shaft receiving an input torque; an output shaft outputting a shifted torque; a first planetary gear set having a first rotation element, a second rotation element, and a third rotation element; a second planetary gear set having a fourth rotation element, a fifth rotation element, and a sixth rotation element; a third planetary gear set having a seventh rotation element, an eighth rotation element, and a ninth rotation element; a fourth planetary gear set having a tenth rotation element, an eleventh rotation element, and a twelfth rotation element; a first shaft fixedly connected to the input shaft, the third rotation element, and the fifth rotation element; a second shaft fixedly connected to the ninth rotation element and the eleventh rotation element, and selectively connectable to the input shaft; a third shaft fixedly connected to the eighth rotation element, the twelfth rotation element, and the output shaft; a fourth shaft fixedly connected to the first rotation element; a fifth shaft fixedly connected to the second rotation element and the sixth rotation element; a sixth shaft fixedly connected to the tenth rotation element; and a plurality of shafts, each of which is selectively connectable to a transmission housing and fixedly connected to a rotation element of the first and second planetary gear sets which is not fixedly connected to the first to sixth shafts.
