Patent attributes
The present invention relates to a power transmission for a hybrid vehicle with a more compact and lightweight design. The power transmission of the invention includes: an engine; a first shaft; a first planetary gear set disposed on the first shaft; a first motor/generator unit connected to the first planetary gear set; a second shaft disposed in parallel with the first shaft, the second shaft having a mediate gear; a second planetary gear set disposed on the second shaft; a second motor/generator unit connected to the second shaft; and a differential unit having a final gear connected to the mediate gear of the second shaft. In this manner, power is transmitted through the power transmission system by virtue of the external intermeshing of the first and second ring gears.
