<P>PROBLEM TO BE SOLVED: To provide a driving device for a hybrid vehicle capable of cooling both a first motor and a second motor, and optimizing the path of refrigerant and the position of an oil sump. <P>SOLUTION: The driving device for the hybrid vehicle includes a refrigerant feeding means 72 for feeding the refrigerant to cool a first motor 20 and a second motor 30, a first path 81 for cooling the first motor 20 and the second motor 30 with the refrigerant to be fed from the refrigerant feed means 72, a second path 82 for lubricating and cooling a power transmission mechanism 40 with the refrigerant to be fed from the refrigerant feed means 72, and a refrigerant sump 73 for storing the refrigerant flowing from the first path 81 and the second path 82. The first path 81 is constituted so that the refrigerant cooling the first motor 20 is returned to the refrigerant sump 73 through the second motor 30. The refrigerant sump 73 is arranged below the second motor 30 and the power transmission mechanism 40 so that at least a part thereof overlaps the second motor 30 and the power transmission mechanism 40 in the axial direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
