| 摘要 |
The present invention relates to an automatic transmission for vehicles, whose weight, length, and manufacturing cost are reduced as a consequence of simplifying a structure thereof by removing a torque converter. An automatic transmission for vehicles according to an exemplary embodiment of the present invention may include a first shift portion outputting two intermediate rotational speeds of a reduced rotational speed and a same rotational speed by using torque received through a first variable input pathway selectively connected to a first input shaft and an input pathway fixedly connected to the first input shaft, and a second shift portion including first, second, third, and fourth gears and a reverse gear that respectively achieve first, second, third, and fourth gear ratios and a reverse gear ratio, changing each intermediate rotational speed received from the first shift portion into five final rotational speeds, and outputting the same.
