Abstract

A planetary gear train of an automatic transmission for a vehicle is provided. Ten or more forward speeds and one or more reverse speed are achieved by a planetary gear train of an automatic transmission for a vehicle. The vehicle includes an input shaft, an output shaft, four planetary gear sets respectively having three rotational elements, and six control elements to selectively connect the rotational elements and a transmission housing.

Description

technical field [0001] The present invention relates to automatic transmissions for vehicles, and more particularly, to a planetary gear train for automatic transmissions for vehicles that minimizes complexity, achieves at least ten forward speeds and at least one reverse speed, The power transmission performance and fuel consumption are improved by the multiple gears of the automatic transmission, and the driving stability of the vehicle is improved by using the low rotation speed of the engine. Background technique [0002] Generally, in the field of automatic transmissions, more shift gears provide a technique for improving fuel consumption and drivability of a vehicle. Specifically, rising oil prices have led to a need to improve vehicle fuel consumption. In other words, research has been done on engines to achieve weight reduction and improve fuel consumption, and research has been done on automatic transmissions to provide better drivability and better fuel consumptio...
