Hybrid vehicle drive system, wherein mechanism for synthesizing engine and motor outputs is disposed adjacent to transmission
First Claim
1. A hybrid drive system for a motor vehicle, including an electric motor operated by an electric energy, an engine operated by combustion of a fuel, a transmission, and a synthesizer mechanism which includes hydraulically operated clutch means and which mechanically synthesizes an output of said engine and an output of said electric motor for transmitting a resultant of said outputs of said engine and said electric motor to said transmission, wherein an improvement comprises:
- said synthesizer mechanism and said transmission being disposed adjacent to each other; and
a housing which has a partition wall which divides said housing into a first portion and a second portion which are fluid-tightly separated from each other, said engine and said electric motor accommodated in said first portion and said synthesizer mechanism and said transmission accommodated in said second portion.

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.
