Abstract
In a case where a motor shaft of a driving electric motor extends in a rightward and leftward direction, and one end portion in the rightward and leftward direction is coupled to a transmission, in a saddle-type electric vehicle such as an electric motorcycle, a transmission accommodating section of a motor unit case is fastened at right and left sides to a vehicle body frame, and a motor accommodating section is coupled to the transmission accommodating section at one end portion in the rightward and leftward direction. Thus, misalignment of bearings of the motor shaft due to deflection of the motor unit case can be suppressed while reducing a weight of the motor unit case.
Claims8
A saddle-type electric vehicle comprising:
- an electric motor for driving the electric vehicle;
- a power transmission mechanism for transmitting driving power generated by the electric motor;
- and
- a motor unit case including a motor accommodating section for accommodating the electric motor and a transmission mechanism accommodating section for accommodating the power transmission mechanism such that the motor accommodating section and the transmission mechanism accommodating section have a unitary construction;
- wherein an output shaft of the electric motor extends in a rightward and leftward direction of the vehicle, and one end portion of the output shaft in the rightward and leftward direction is coupled to the power transmission mechanism;
- and wherein the transmission mechanism accommodating section of the motor unit case is fastened at right and left sides to a vehicle body frame, and the motor accommodating section is joined at one end portion in the rightward and leftward direction to the transmission mechanism accommodating section.
