摘要

A rotary electric machine unit including a rotary electric machine, and an electric power conversion device having a plurality of power modules. The rotary electric machine includes a stator, a rotor, and a housing. The housing includes a housing flow path through which a refrigerant flows. The power modules of the electric power conversion device and the rotary electric machine are configured to be cooled by the refrigerant.

說明書

The side gears 823a and 823b each have a rotation axis orthogonal to the rotation axis of the pinion gear 822, and are arranged coaxially with each other. The side gears 823a and 823b are coaxially arranged on the motor shaft portion 708 and mesh with the pinion gear 822. Of the side gears 823a and 823b, the first transmission shaft portion 840a is coaxially fixed to the first side gear 823a, and the second transmission shaft portion 840b is coaxially fixed to the second side gear 823b. In the differential gear 820, when the differential case 821 is rotating and the pinion gear 822 is not rotating, the first side gear 823a and the second side gear 823b rotate at the same speed. On the other hand, when the pinion gear 822 rotates, the first side gear 823a and the second side gear 823b rotate at different speeds.
