VEHICLE DRIVE DEVICE

摘要

A vehicle drive device having a case that 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 rotor member and the coupling input member are coupled so as to rotate in conjunction with each other to form a power transfer member. The vehicle drive device further includes a first bearing that supports the power transfer member from a second axial direction side so as to be rotatable with respect to the support wall portion, the second axial direction side being an opposite side from the first axial direction side, and a second bearing that supports the power transfer member from the first axial direction side 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; the rotor member and the coupling input member are coupled so as to rotate in conjunction with each other to form a power transfer member; and the vehicle drive device includes a first bearing that supports the power transfer member from a second axial direction side so as to be rotatable with respect to the support wall portion, the second axial direction side being an opposite side from the first axial direction, and a second bearing that supports the power transfer member from the first axial direction side so as to be rotatable with respect to the support wall portion.
