Abstract

An electric motorcycle in which a driving force is transmitted to a wheel by connection with less waste. The electric motorcycle is one in which a battery is disposed in a position behind a handle and in front of a seat. A driving motor is located below the seat, and a lower part of a swing arm is supported by an attachment section provided in a pivot plate, a drive shaft that transmits a driving force output from the driving motor to a wheel being supported by the swing arm.

First claim

The invention claimed is:

1. An electric motorcycle in which a battery is disposed in a position behind a handle and in front of a seat, wherein
a driving motor is located below the seat,
the driving motor is disposed further forward than a rear end of a frame connecting a head pipe and a pivot plate and is supported by a vehicle body frame in a position overlapping the frame in a vehicle side view,
the pivot plate extends downward from rear end parts of the frame, and
a lower part of a swing arm is supported by an attachment section provided in the pivot plate, a drive shaft that transmits a driving force output from the driving motor to a wheel being supported by the swing arm.

2. The electric motorcycle according to claim 1 , wherein an output shaft of the driving motor overlaps the frame in the vehicle side view.

3. The electric motorcycle according to claim 1 , wherein the attachment section is a through-hole provided in a height position substantially in a center of the pivot plate, and a pivot shaft supporting a lower part of the swing arm is supported in through-hole.

4. The electric motorcycle according to claim 1 , wherein a radiator and a radiator fan are disposed in a position below the seat and behind the driving motor.

5. The electric motorcycle according to claim 1 , wherein power control unit is disposed above the battery and in front of the driving motor.

6. The electric motorcycle according to claim 1 , wherein at least part of the driving motor is located above the battery.

7. The electric motorcycle according to claim 6 , wherein a front lower part of the driving motor is located in a rear end upper part of the battery.
