| 摘要 |
The present invention relates to a transmission for a hybrid vehicle, achieving multi-speeds in an electric vehicle (EV)/hybrid electric vehicle (HEV) drive mode to increase shifting efficiency and improving fuel efficiency and capable of allowing drive in a series mode and in a parallel mode. According to the present invention, the transmission for a hybrid electric vehicle comprises: an input shaft connected to an engine; an output shaft arranged in parallel with respect to the input shaft; a first hollow shaft installed on the outer circumferential surface of one side of the input shaft; a second hollow shaft installed on the outer circumferential surface of the other side of the input shaft; a first motor connected to the first hollow shaft; a second motor connected to the second hollow shaft; a first transmission output part arranged between the first hollow shaft and the output shaft; a second transmission output part arranged between the second hollow shaft and the output shaft; a first synchronizer synchronously connecting the first hollow shaft to the first transmission output part; and a second synchronizer synchronously connecting the second hollow shaft to the second transmission output part. |
