Abstract: A device for driving a vehicle including an engine that serves as a power source of the vehicle, and a transmission that is connected to the engine, the engine and the transmission being arranged transversely such that an axial direction of an output shaft of the engine accords with a right-left direction of the vehicle includes a motor generator (MG) that serves as a power source of the vehicle, and a speed reducer that is connected to the MG. The MG and at least a part of the speed reducer are arranged outside of an engine compartment that accommodates the engine and the transmission. An output shaft of the speed reducer is connected to a power transmission system, which transmits power of an output shaft of the transmission to a drive shaft of a vehicle wheel to be capable of transmitting its power to the power transmission system.

Abstract: A rotating electric machine includes a rotating shaft, a rotor fixed on the rotating shaft, a stator, a housing, a liquid coolant and a flow direction regulating member. The stator is arranged so that a radially inner peripheral surface of the stator radially faces a radially outer peripheral surface of the rotor through an annular gap formed therebetween. The housing covers both axial ends of the stator and rotatably supports the rotating shaft. The liquid coolant is provided in an internal space formed in the housing to flow into at least part of the annular gap formed between the radially inner peripheral surface of the stator and the radially outer peripheral surface of the rotor. The flow direction regulating member axially faces an axial end face of the rotor through an axial gap formed therebetween and regulates the flow direction of the coolant by means of the axial gap.

Abstract: In a multi-gap rotating electric machine, a side stator coil is received in a side space formed in a housing to connect radially inner and radially outer stator coils across a rotor. A cooling oil flow adjustment member is provided to adjust flow of cooling oil in the side space. The adjustment member has cooling oil guide channels formed on an uneven surface thereof facing the side stator coil. When viewed along a central axis of a rotating shaft: on an upper apart of the uneven surface which is located above the central axis, the cooling oil guide channels spread from a reference line to both sides of the reference line while extending downward; and on a lower part of the uneven surface which is located below the central axis, the cooling oil guide channels converge on the reference line from both sides of the reference line while extending downward.

Abstract: A detection part of a temperature detection element is mounted to ends of drawn portions which are further protruded in the axial direction than coil end portions. The detection part and the ends of the drawn portions provided with the detection part are covered with a covering member. The ends of the drawn portions provided with the detection part and covered with the covering member are inserted into a through hole of a wall member which is disposed so as to axially face an axial end face of a stator core. In this case, the detection part is located at a position deeper (on the rear side) than a position of a stator core side opening of the through hole.

Abstract: A rotating electrical machine has a housing, a stator having a stator core and a rotor having a rotor core and rotor side plates rotatably supported by the housing. The rotor core is arranged to have a gap between the end surfaces of the rotor core and the stator. Oil containers are arranged on at least one surface of the rotor side plate. Each oil container has a scoop-up part and an exhaust outlet formed on end sections thereof. When the rotor is rotating, the scoop-up part scoops up an oil stored in the housing, the oil and inside air are compressed in the oil container, and the exhaust outlet exhausts the oil and compressed air to the coil end of the stator. The housing stores the oil at a lowermost side thereof so that the scoop-up part and the exhaust outlet are immersed in the oil.
