Abstract
A power transmission device for a hybrid vehicle includes a series-parallel type power transmission path capable of varying an engine output for each driving mode, using a Ravigneaux gear train and two or more clutches, to improve the fuel efficiency of the hybrid vehicle. The power transmission device includes two or more kinds of engine fixing gear stages capable of distributing the output of the engine to a driving wheel, which are implemented using the Ravigneaux gear train, in which a single pinion planetary gear is integrally configured with a double pinion planetary gear including a carrier obtained by combining two pinion gears with the two or more clutches.
