HYBRID DRIVE DEVICE

摘要

A hybrid drive device has a drive device input shaft (I1) connected to an engine (EG), a rotating electric machine (MG), a transmission (SC) for changing the speed of driving rotation transmitted from either the rotating electric machine (MG) or the drive device input shaft (I1) or from both of them and outputting rotation having the changed speed, a transmission case (H2) for receiving the transmission (SC), and a case (H1) for the rotating electric machine, having a joint surface to which the transmission case (H2) is joined. On the inner periphery of the case (H1) for the rotating electric machine is provided a step section (e1) that is reduced in diameter from the input end side of the input shaft. A partition wall (SW) for supporting the rotating electric machine from the input end side of the input shaft is fixed to the step section (e1).
