Description

technical field [0001] The present invention relates to automatic transmissions for vehicles. More particularly, the present invention relates to a planetary gear train of an automatic transmission for a vehicle, which improves power delivery performance and fuel economy by realizing ten forward speed gears with a minimum number of components, and by using The working point of the region is used to improve the static drive of the vehicle. Background technique [0002] In general, automatic transmissions implementing more speed gears have been developed to improve fuel economy and optimize drivability. Rising oil prices in recent years have sparked intense competition to improve fuel consumption in vehicles. [0003] Therefore, people have begun to reduce the weight and improve the fuel economy by downsizing the engine, and ensure drivability and fuel economy by multi-stage speed gears of the automatic transmission. [0004] However, in an automatic transmission, as the nu...
