Abstract
A vehicle drive device includes a rotary electric machine including a stator and a rotor, a power transmission mechanism drivingly connected to the rotor, a differential device including a differential ring gear, a differential case, and a differential mechanism, and a case. The case includes a partition wall disposed between the rotary electric machine and the differential device. The partition wall has an opening at a portion where a distance between a stator core and the differential device is shortest so that part of the stator core is exposed on a differential device side.
Claims6
A vehicle drive device comprising:
- a rotary electric machine including a stator including a stator core and coil ends that protrude from the stator core on both sides in an axial direction, and a rotor provided so as to be rotatable relative to the stator;
- a power transmission mechanism drivingly connected to the rotor;
- a differential device including a differential ring gear drivingly connected to the power transmission mechanism, a differential case integrated with the differential ring gear, and a differential mechanism contained in the differential case;
- and
- a case that houses the rotary electric machine, the power transmission mechanism, and the differential device, wherein
- the case includes a partition wall disposed between the rotary electric machine and the differential device, and
- the partition wall has an opening at a portion where a distance between the stator core and the differential device is shortest so that part of the stator core is exposed on the differential device side.
