Abstract
A case includes a rotary electric machine housing chamber that houses a rotary electric machine, and an oil storage space provided in a lower part of the rotary electric machine housing chamber. At least one of a pair of output members is disposed in a space that communicates with the rotary electric machine housing chamber. An oil pump is disposed in the oil storage space at a position on a lower side of a first axis that is a rotation axis of the rotary electric machine and a second axis that is a rotation axis of the pair of output members so as to overlap an output gear in an axial view along the second axis.
Claims9
A vehicle drive device comprising:
- a rotary electric machine;
- a pair of output members drivingly connected to a pair of wheels;
- a transmission mechanism configured to transmit a driving force between the rotary electric machine and the pair of output members;
- an oil pump configured to supply cooling oil to the rotary electric machine;
- and
- a case that houses the rotary electric machine, the transmission mechanism, and the oil pump, wherein:
- the rotary electric machine and the pair of output members are disposed separately on two parallel axes;
- the transmission mechanism includes a differential gear mechanism configured to distribute the driving force transmitted from the rotary electric machine side to the pair of output members, and an output gear drivingly connected to the pair of output members coaxially with the pair of output members;
- the output gear is connected to a differential case of the differential gear mechanism so as to rotate integrally with the differential case,
- the case includes a rotary electric machine housing chamber that houses the rotary electric machine, and an oil storage space provided in a lower part of the rotary electric machine housing chamber;
- at least one of the pair of output members is disposed in a space that communicates with the rotary electric machine housing chamber;
- the oil pump is disposed in the oil storage space at a position on a lower side of a first axis that is a rotation axis of the rotary electric machine and a second axis that is a rotation axis of the pair of output members so as to overlap the output gear in an axial view along the second axis, and
- the oil storage space is a common space that includes both the oil pump and the rotary electric machine.
