Abstract
A parallel hybrid vehicle includes: an engine serving as a drive source for travel of the parallel hybrid vehicle; an electric motor serving as a drive source for travel of the parallel hybrid vehicle; and a water pump that causes a cooling liquid to circulate in a cooling path. The water pump is connected to the engine to receive power from the engine and is connected to the electric motor to receive power from the electric motor.
Claims9
A parallel hybrid vehicle comprising:
- an engine serving as a drive source for travel of the parallel hybrid vehicle;
- an electric motor serving as a drive source for travel of the parallel hybrid vehicle;
- a water pump that causes a cooling liquid to circulate in a cooling path;
- a main clutch provided in a power transmission route between a crankshaft of the engine and the input shaft of the transmission;
- a first one-way clutch that permits transmission of power from the engine to the water pump;
- a second one-way clutch that permits transmission of power from the electric motor to the water pump, wherein
- the water pump is connected to the engine to receive power from the engine and is connected to the electric motor to receive power from the electric motor;
- a transmission comprising an input shaft, an output shaft, and a gear train, the transmission being configured to change the speed of rotational power output from the engine and the electric motor at a selected gear ratio and configured to output the resulting rotational power to a drive wheel, wherein
- rotational power of the engine is transmitted to the electric motor via the input shaft of the transmission.
