Abstract:
A planetary gear train of an automatic transmission for a vehicle is provided. The planetary gear train includes an input shaft that receives an engine torque, an output shaft that outputs a shifted torque, and planetary gear sets. Additionally, shafts are connected with respective rotational elements. The planetary gear train thus improves power delivery performance and reduces fuel consumption by achieving nine forward speed stages using a minimum number of constituent elements.
