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.

Claim (Index 1):
A power transmission apparatus, comprising:\n an internal combustion engine; a first electric motor; a second electric motor; a power distribution mechanism comprising a first differential transmission which is connected to the internal combustion engine and the first electric motor and in which at least three rotation elements enable to rotate in differential motions to one another; a power combining mechanism comprising a second differential transmission which is connected to the power distribution mechanism, the second electric motor and an output shaft and in which four rotation elements enable to rotate in differential motions to one another; a first fixing mechanism which enables to fix selectively any one of the rotation elements of the power combining mechanism so as not to rotate; and a second fixing mechanism which enables to fix selectively a rotation element of the power distribution mechanism which is connected to the internal combustion engine of the power distribution mechanism so as not to rotate, wherein the power combining mechanism is configured so that the rotation element which is connected to the power distribution mechanism, the rotation element which is connected to the output shaft, the rotation element which is connected to either of the second electric motor and the first fixing mechanism, and the rotation element which is connected to the other of the second electric motor and the first fixing mechanism are aligned sequentially in that order on a nomographic chart.
