Vehicle drive device
First Claim
1. A vehicle drive device, comprising:
- a rotor rotatably supported, via a rotor support member, radially inside a stator that has coil end portions on both sides in an axial direction, and which is structured so that oil is supplied from an axial first direction side, which is one side in the axial direction of the rotor, to the coil end portions on the both sides in the axial direction;
the rotor support member is configured with a radially extending portion that extends in a radially inward direction from the rotor and is disposed radially inward from the rotor;
an oil collecting portion provided at an end of the rotor support member located on the axial first direction side, the oil collecting portion configured to collect oil scattered from the radially inward direction of the rotor support member; and
a communication oil passage provided in at least one of the rotor and the rotor support member, and communicating with a first opening and a second opening from the oil collecting portion, whereinthe first opening opens radially inside the coil end portion on the axial first direction side, andthe second opening opens radially inside the coil end portion on an axial second direction side, which is the other side in the axial direction of the rotor.

Abstract
A rotating electrical machine configured with a rotor and stator. The rotor is rotatably supported radially inside of a stator that has coil end portions on both sides in an axial direction, and which is structured so that oil is supplied from an axial first direction side to the coil end portions on the both sides in the axial direction. A communication oil passage provided in at least one of the rotor and the rotor support member, is configured to communicate with a first opening and a second opening from an oil collecting portion. The first opening opens radially inside the coil end portion on the axial first direction side, and the second opening opens radially inside the coil end portion on an axial second direction side, which is the other side in the axial direction of the rotor.

19. A vehicle drive device for an internal combustion engine, the vehicle drive device comprising:
-
a rotating electrical machine comprising; a rotor rotatably supported, via a rotor support member, radially inside a stator that has coil end portions on both sides in an axial direction, and which is structured so that oil is supplied from an axial first direction side, which is one side in the axial direction of the rotor, to the coil end portions on the both sides in the axial direction; an oil collecting portion provided at an end of the rotor support member located on the axial first direction side, the oil collecting portion configured to collect oil scattered from the radially inward direction of the rotor support member; and a communication oil passage provided in at least one of the rotor and the rotor support member, and communicating with a first opening and a second opening from the oil collecting portion, wherein the first opening opens radially inside the coil end portion on the axial first direction side, and the second opening opens radially inside the coil end portion on an axial second direction side, which is the other side in the axial direction of the rotor; and a clutch configured to separate coupled states between the combustion engine and the rotating electrical machine, the clutch disposed radially inward of the rotating electrical machine.
