Abstract

A power transmission apparatus has a power distribution mechanism which is connected to an engine and a first motor-generator an in which at least three rotation elements enable to rotate in differential motions to one another, a power combining mechanism which is connected to the power distribution mechanism, a second motor-generator and an output shaft and in which four rotation elements enable to rotate in differential motions to one another, a brake mechanism which enables to selectively fix a rotation element of the power combining mechanism and a brake mechanism which enables to selectively fix a rotation element of the power combining mechanism which is connected to the engine.
