Patent ID: 7350603

Claim:
A hybrid drive unit comprising: an input shaft which is positioned to a rear of an internal combustion engine and which extends in front-rear directions of a vehicle; an output shaft that is coaxially aligned with the input shaft; a hybrid mechanism including at least one electric motor, the hybrid mechanism changing a driving force transmitted from the internal combustion engine to the input shaft and then transmitting the driving force to the output shaft; a transfer that distributes the driving force of the output shaft to front and rear wheels; and a case member that houses the input shaft, the output shaft, the hybrid mechanism and the transfer that are positioned to the rear of the internal combustion engine, the case member comprising: (i) a shaft that is connected to the internal combustion engine; and (ii) a first attachment portion which configures a first mounting portion between a vehicle body and the case member and which is provided between the at least one electric motor and the transfer, wherein the at least one electric motor and the transfer are respectively positioned to a front and a rear of the first mounting portion, the hybrid mechanism includes a speed change unit which is positioned further in the rear direction from the at least one electric motor and which changes the driving force, the first attachment portion is provided between the speed change unit and the transfer, the hybrid mechanism comprises a first electric motor for generating electric power that is one of the at least one electric motor, a force distribution planetary gear, a second electric motor for driving force assistance that is another of the at least one electric motor, and the speed change unit, and the first electric motor, the force distribution planetary gear, the second electric motor and the speed change unit are positioned in that order in the rear direction from the internal combustion engine.
