Vehicle drive device

摘要

A vehicle drive device for a rotary electric machine. A case of the device includes a support wall portion that extends in a radial direction of the rotary electric machine at a location between the rotary electric machine and the fluid coupling in the axial direction. A first bearing and a second bearing that is separate from the first bearing are disposed at different positions in the radial direction from each other, the first bearing being configured to support the rotor member in the radial direction so as to be rotatable with respect to the support wall portion, and the second bearing being configured to support the coupling input member in the radial direction so as to be rotatable with respect to the support wall portion.

1. A vehicle drive device comprising a rotary electric machine, a fluid coupling disposed coaxially with the rotary electric machine on a first axial direction side with respect to the rotary electric machine, and a case that houses the rotary electric machine and the fluid coupling, the first axial direction side being one side in an axial direction with respect to the rotary electric machine, and the fluid coupling including a coupling input member drivably coupled to a rotor member of the rotary electric machine and a coupling output member drivably coupled to wheels, wherein:
the case includes a support wall portion that extends in a radial direction of the rotary electric machine at a location between the rotary electric machine and the fluid coupling in the axial direction; and a first bearing and a second bearing that is separate from the first bearing are disposed at different positions in the radial direction from each other, the first bearing being configured to support the rotor member in the radial direction so as to be rotatable with respect to the support wall portion, and the second bearing being configured to support the coupling input member in the radial direction so as to be rotatable with respect to the support wall portion.
