Abstract
A power train may include an engine including a crankshaft and an engine block, a rotor portion connected to the crankshaft and of which a magnet is connected to a first side thereof, a stator portion disposed between the rotor portion and the engine block and a cylinder block water jacket formed on the engine and to which a motor cooling port for cooling a motor is formed.
Claims17
A power train comprising:
- an engine including a crankshaft and an engine block;
- a rotor portion connected to the crankshaft and of which a magnet is connected to a first side of the rotor portion;
- a stator portion disposed between the rotor portion and the engine block;
- a cylinder block water jacket disposed on the engine, the cylinder block water jacket having a motor cooling port for cooling a motor;
- and
- a motor housing connected to the engine block and having a housing hole,
- wherein the motor housing includes an inlet through which coolant flows from the motor cooling port into the motor housing and an outlet through which coolant exits the motor housing, for cooling the stator portion, and
- wherein the rotor portion comprises:
- a protrude portion connected to the crankshaft through the housing hole;
- and
- a disk connected to the protrude portion and to which the magnet is connected.
