摘要： In a cooling path of a motor 14, an oil control valve 45 is provided between a path LN21 and a path LN11, a heat exchanger 42 is provided between a path LN11 and a path LN31, and a heat exchanger 43 is provided between a path LN12 and a path LN32. In a motor-drive mode, a valve control section 52 switches a valve 45 to the path LN11 side when an engine temperature T is lower than a first threshold T TH1 , and switches the valve 45 to the path LN12 side when the engine temperature T is equal to or higher than the first threshold T TH1 . In the heat exchanger 42, motor cooling oil and engine oil exchange heat. In the heat exchanger 43, the motor cooling oil and a coolant for the engine exchange the heat.

摘要： A drive unit 10 as a drive source for travel of the vehicle has an engine 13 and a motor 14. A torque tube 47 is connected to a rear portion of the motor 14. The torque tube 47 covers a propeller shaft that is coupled to an output shaft of the drive unit 10. An inverter 27 is arranged above the torque tube 47. The inverter 27 is separated from the drive unit 10 and is separated from the torque tube 47. A terminal 27a of the inverter 27 and a terminal 14e of the motor 14 are connected by three wire harnesses 49. Each of the wire harnesses 49 has a wire length that is longer than a linear distance connecting the terminal 27a and the terminal 14e by the shortest distance.

摘要： A drive unit has engines and a motor that are adjacent to each other in a longitudinal direction. The engines are provided with an engine oil path and a coolant path for cooling. The motor is provided with a motor cooling oil path for cooling. A heat exchanger, in which engine oil and motor cooling oil exchange heat, and a heat exchanger, in which a coolant and the motor cooling oil exchange heat, are provided. Size in vertical and lateral directions of the motor is smaller than size in the vertical and lateral directions of each of the engines. The heat exchanger is attached to an upper portion of a side circumferential portion of the motor, and the heat exchanger is attached to a lower portion of the side circumferential portion of the motor.

摘要： A drive unit for travel of the vehicle includes an engine 13 and a motor 14. The engine 13 is a rotary engine and has an engine output shaft 132 and an engine housing 131. The motor has a motor output shaft 142, a rotor 143, and a stator 145 that are accommodated in a motor housing 141. The engine housing 131 of the engine 13 and the motor housing 141 of the motor 14 are directly joined to each other. The engine output shaft 132 and the motor output shaft 142 are directly joined to each other. The rotor 143 of the motor 14 has: a main body section 143b that generates a rotational magnetic field with the stator 145; and a weight section 143a that functions as a balance weight of the engine.

摘要： A drive unit for vehicle travel has the engine and a motor 14. The motor 14 is arranged adjacent to a rear side of the engine. In housings 14a, 14b of the motor 14, parts of oil control valves 45, 46 and motor cooling oil paths LN11 to LN12, LN21to LN22, LN31 to LN35, through each of which motor cooling oil flows, are provided. The motor cooling oil flowing through the motor cooling oil paths LN11, LN31 exchanges heat with engine oil in a heat exchanger 42. The motor cooling oil flowing through the motor cooling oil paths LN12, LN32 exchanges heat with an engine cooling coolant in a heat exchanger 43.
