Patent ID: 7891449

Claim:
A hybrid drive apparatus, comprising: a drive apparatus input shaft that is connected to an engine; a rotary electric machine; a transmission that is capable of changing a speed of rotation from a transmission input shaft and outputting a resulting rotation to a transmission output shaft; an output mechanism that connects the transmission output shaft and drive wheels; a drive transfer mechanism that links a rotor of the rotary electric machine and the transmission input shaft; and a clutch that enables interrupting and connecting of drive power between the drive apparatus input shaft and the transmission input shaft, wherein: the drive transfer mechanism includes a speed reduction mechanism that reduces a rotation speed from the rotary electric machine and transmits a resulting rotation to the transmission input shaft, the drive apparatus input shaft and the transmission input shaft are disposed concentrically on a first axis, and in an axial direction of the first axis, the clutch and the speed reduction mechanism are provided between the transmission and the rotary electric machine, from an engine side, the rotary electric machine, the speed reduction mechanism, the clutch, and the transmission are disposed in sequence, the clutch comprises a clutch drum that serves as a clutch output member, and the clutch drum is connected to the transmission input shaft, the speed reduction mechanism is disposed on an opening side of the clutch drum, and a rotation speed from the speed reduction mechanism is transferred to the transmission input shaft via the clutch drum, and the clutch comprises a clutch hub that serves as a clutch input member, and the clutch hub rotates integrally with the drive apparatus input shaft.
