Vehicle drive device
First Claim
1. A drive device for a vehicle, comprising:
- an input member drivingly connected to an internal combustion engine;
an output member drivingly connected to a wheel;
a rotary electric machine;
a fluid coupling drivingly connected to the rotary electric machine;
an engagement device selectively drivingly connecting the input member with the rotary electric machine and the fluid coupling by hydraulic pressure; and
a case housing at least the rotary electric machine, the engagement device, and the fluid coupling, whereinthe case includes a support wall extending at least radially on a side in an axial first direction that is axially on an internal combustion engine side relative to the engagement device, and a cylindrical projecting portion projecting from the support wall toward a side in an axial second direction that is in a direction opposite to the axial first direction,the engagement device includes an operating oil pressure chamber supplied with the hydraulic pressure,a rotor member of the rotary electric machine is radially supported by the cylindrical projecting portion in a rotatable state via a support bearing, andthe cylindrical projecting portion is formed with an operating oil supply passage supplying oil to the operating oil pressure chamber.

Abstract
A drive device for a vehicle configured between an internal combustion engine and a wheel. The drive device includes a rotary electric machine, and an engagement device connecting the drive device to the engine by a fluid coupling using hydraulic pressure. A case houses at least a portion of the drive device and includes a support wall extending radially, and a cylindrical projecting portion projecting from the support wall toward a side in an axial second direction that is in a direction opposite to the axial first direction. The engagement device includes an operating oil pressure chamber supplied with the hydraulic pressure. A rotor member of the rotary electric machine is radially supported by the cylindrical projecting portion in a rotatable state via a support bearing. The cylindrical projecting portion is formed with an operating oil supply passage supplying oil to the operating oil pressure chamber.
