Abstract

An electric vehicle includes: an engine which is disposed on a front side in the vehicle, and which is configured to drive rear wheels of the vehicle, the engine which includes a crank shaft that is extended in a front/back direction of the vehicle; and a drive motor which is arranged in line with the engine in a width direction of the vehicle, and which is disposed on an air intake side of the engine, the drive motor which is configured to drive front wheels of the vehicle.

Claims

1. An electric vehicle comprising:

an engine disposed on a front of vehicle, and configured to drive rear wheels of the vehicle, the engine including a crank shaft extending in a front/back direction of the vehicle;

a first output transmission mechanism disposed offset in a width direction of the vehicle with respect to the crank shaft and laterally on a side of the engine opposite an exhaust pipe of the engine; and

a drive motor arranged opposing the first output transmission mechanism in the width direction of the vehicle, such that the first output transmission is disposed between the engine and the drive motor in the width direction of the vehicle,

wherein the engine, the drive motor, and the first output transmission are aligned along a line parallel to the width direction of the vehicle.

2. The electric vehicle according to claim 1, wherein

the first output transmission mechanism is configured to transmit an output from the drive motor directly to a front drive shaft of the front wheels.

3. The electric vehicle according to claim 1, further comprising:

a power generation motor arranged offset with respect to the crank shaft in the width direction of the vehicle, and configured to generate electric power using an output of the engine; and

a second output transmission mechanism disposed between the engine and the power generation motor, and configured to transmit the output from the engine to the power generation motor.

4. The electric vehicle according to claim 3, wherein

the power generation motor is disposed to be offset with respect to the crank shaft in the width direction of the vehicle and in a direction opposite to the exhaust pipe.

5. The electric vehicle according to claim 2, further comprising:

a power generation motor arranged offset with respect to the crank shaft in the width direction of the vehicle, and configured to generate electric power using an output of the engine; and

a second output transmission mechanism disposed between the engine and the power generation motor, and configured to transmit the output from the engine to the power generation motor.

6. The electric vehicle according to claim 5, wherein

the power generation motor is disposed to be offset with respect to the crank shaft in the width direction of the vehicle and in a direction opposite to the exhaust pipe.
