Abstract: A planetary gear train of an automatic transmission may include a first planetary gear set including a first ring gear directly connected to a first shaft, a first planet carrier, and a first sun gear, a second planetary gear set disposed on a second shaft and including a second sun gear receiving an inverse rotation speed from the first planet carrier, a second ring gear selectively connected to the second shaft, and a second planet carrier, a third planetary gear set including a third sun gear directly connected to the second shaft, a third ring gear selectively connected to the first sun gear, and a third planet carrier directly connected to the second planet carrier and directly connected to an output gear, three transfer gears interposed between rotation elements, and five frictional elements selectively interconnecting the rotation elements or selectively connecting the rotation elements to a transmission housing.

Abstract: A planetary gear train of an automatic transmission includes: a first shaft receiving engine torque; a second shaft parallel with the first shaft and selectively inversely receiving rotation of the first shaft; a first planetary gear set disposed on the first shaft and including a first, second and a third rotation paths; a compound planetary gear set formed by combining a second planetary gear set and a third planetary gear set, and including a fourth, fifth, sixth and seventh rotation paths; three transfer gears interposed between the rotation shafts, and configured to transfer an inverse rotation speed to the second shaft and the rotation paths of the compound planetary gear set; and five frictional elements interconnecting the rotation paths or selectively connecting the rotation paths to a transmission housing.
