PLANETARY GEAR TRAIN OF AUTOMATIC TRANSMISSION FOR VEHICLE

摘要

A planetary gear train of an automatic transmission for a vehicle may include an input shaft receiving torque, an output shaft disposed in parallel with and apart from the input shaft, a first planetary gear set having at least three rotation elements, a second planetary gear set having at least three rotation elements, a first rotation shaft, a second rotation shaft, a third rotation shaft, and a fourth rotation shaft.

主权项

1. A planetary gear train of an automatic transmission for a vehicle comprising:
an input shaft receiving torque; an output shaft disposed in parallel with and apart from the input shaft; a first planetary gear set having three rotation elements; a second planetary gear set having three rotation elements, wherein one rotation element is integrally formed with or is directly connected to one rotation element of the first planetary gear set; a first rotation shaft directly connected to the one rotation element of the first planetary gear set and/or the one rotation element of the second planetary gear set, and selectively connected to the input shaft; a second rotation shaft directly connected to another rotation element of the first planetary gear set and another rotation element of the second planetary gear set, and directly connected to the output shaft; a third rotation shaft directly connected to the other rotation element of the first planetary gear set and selectively connected to the input shaft or a transmission housing; and a fourth rotation shaft directly connected to the other rotation element of the second planetary gear set, and selectively connected to the input shaft through two paths or selectively connected to the transmission housing.
