Problems solved by technology

[0010] However, in the electric vehicle described in Patent Document 1, since the rear wheels are driven by a motor coaxially provided with the rear axle, and the drive torque is obtained without a reduction mechanism, a dedicated motor with a large diameter is required, so it is difficult to provide Lightweight and inexpensive electric motorcycle, and since the electric motor and the control unit (motor driver) are housed in one arm provided on the left side of the swing arm in the vehicle width direction, the weight distribution on the left side of the vehicle body is relatively Larger than the right side of the hull resulting in poor weight balance
Then there is the possibility that the rigidity of the rocker arm must also be increased

Embodiment Construction

[0073] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a side view of a saddle-riding electric vehicle 1 according to an embodiment of the present invention. in addition, figure 2 It is a rear perspective view of the electric vehicle 1 with exterior parts removed. The electric vehicle 1 is a small two-wheeled motor vehicle with a low pedal 9a, and it is configured to use an electric motor 50 built in a rocker arm 12 (refer to Figure 4 ) drives the rear wheel WR. In addition, the high-voltage battery 31 that supplies electric power to the electric motor 50 can be charged by connecting an external power source to a charging port (not shown) provided in the vehicle body.

[0074] A head pipe 3 that rotatably pivotally supports a steering rod 7 a is coupled to a front side end portion of the main frame 2 . A steering handle 7 is attached to the upper portion of the steering rod 7a, and a p...

Abstract

Provided is an electric vehicle that realizes a light electric straddled vehicle using a motor with a small size, and optimizes the left and right weight balances in the width direction of the vehicle with respect to the vehicle body centerline. The electric motor (250) is disposed inside a swing arm (124) of a cantilever type at a position overlapping a projection area of a rear wheel WR when seen from the side portion of the vehicle body. The motor driver (216) is disposed inside the swing arm (124) so that the vehicle body centerline (C) passing through at the front side of the vehicle body in the rear wheel (WR). The position (G2) of the center of gravity of the motor driver (216) is disposed to be offset in the direction opposite to the offset direction of the electric motor (250) with respect to the vehicle body centerline (C).

Description

technical field [0001] The present invention relates to an electric saddle-riding vehicle, in particular to an electric saddle-riding vehicle that drives driving wheels by an electric motor. Background technique [0002] Conventionally, an electric saddle-riding vehicle is known in which driving wheels are driven by an electric motor. [0003] Patent Document 1 discloses an arrangement in which, in a small electric vehicle having a cantilevered rocker arm that pivotally supports the rear wheel with one arm, the electric motor is divided into two parts by using a speed reducer composed of a planetary gear. The output shaft is arranged at the same position as the axle of the rear wheel, and the control device of the electric motor is housed inside the arm. [0004] In addition, in the electric vehicle described above, the arrangement of the electric motor and the storage battery as a power supply source becomes a major factor in terms of vehicle body layout. [0005] Patent ...
