VEHICLE DRIVE DEVICE

DRIVE January 7, 2021
Source
A vehicle drive device includes an electric motor disposed in a wheel, a planetary gear mechanism, and a hub. The electric motor is configured to generate a drive force which drives the wheel. The drive force of the electric motor is transmitted to the planetary gear mechanism. The hub transmits a drive force of the planetary gear mechanism to the wheel. The planetary gear mechanism includes a pinion gear having a first pinion and a second pinion coaxial with the first pinion and having a smaller diameter than the first pinion, a fixed ring gear which engages with the first pinion, and a drive ring gear which engages with the second pinion and transmits a drive force to the hub. The first pinion is disposed at a position away from an end portion of the stator core in a direction in which a rotation center axis of the wheel extends.
