Abstract
A hybrid vehicle drive system including an electric motor operated by electric energy, an engine operated by the combustion of a fuel, a transmission, and a synthesizer mechanism. The synthesizer includes a hydraulically operated clutch system and mechanically synthesizes the output of the engine and the output of the electric motor for transmitting a resultant of these outputs to the transmission. The synthesizer mechanism and the transmission are disposed adjacent to each other, to simplify piping arrangements for supplying the clutch system with a working fluid and lubricating the synthesizer mechanism and transmission.
