Embodiment Construction

[0045] Below, according to Figure 1 ~ Figure 4 The electric vehicle according to the first embodiment of the present invention will be described.

[0046] Such as figure 1 As shown, the electric vehicle of the first embodiment is an electric motorcycle, and has a body frame 11 that constitutes a frame part of the body. A steering shaft 14 provided on a shaft 13 is pivotally supported on the head pipe 12 at the front end of the body frame 11, and a pair of left and right front forks 15 are attached to the shaft 13. A front wheel 16 is pivotally supported at the lower end of these front forks 15, and a handle 17 is attached to the upper part of the shaft 13. Thus, the front wheels 16 can be steered by operating the handle 17.

[0047] In addition, the body frame 11 has a pair of left and right upper frames (main frame) 20 extending from the left and right of the upper part of the head pipe 12 to the upper side and rearward, and from the left and right of the lower part of the head...

Abstract

An electric vehicle includes a vehicle body frame (11); an electric motor (41); a swing arm (34) pivotally supporting a rear wheel (35) at a rear end thereof; a drive shaft (52) for transmitting the driving force of the electric motor (41) to the wheel; and a suspension system (67) connecting the vehicle body frame (11) and the swing arm (34) together. The electric motor (41) is set in a longitudinal layout in which a rotating drive shaft (42) is disposed in a front-rear direction of the vehicle; and is offset from a center to either of left and right sides in a vehicle width direction. The suspension system (67) is disposed under the electric motor (41) and the drive shaft (52), and on the inner sides of the electric motor (41) and the drive shaft (52) in the vehicle width direction, and overlapping the positions of the electric motor (41) and the drive shaft (52) in the front-rear direction.

Description

Technical field [0001] The present invention relates to electric vehicles. Background technique [0002] Among the vehicles that have an electric motor for generating driving force for traveling, there is a vehicle that constitutes a swing arm that supports the rear wheels by a power unit including an electric motor, and the rear wheel is arranged between the swing arm and the body frame above it. A suspension system for wheels (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Publication No. 11-79054 [0004] As described above, if the structure is configured to arrange the suspension system for the rear wheel between the swing arm and the body frame above it, there is a problem that the space above the swing arm cannot be effectively used. Summary of the invention [0005] The object of the present invention is to provide an electric vehicle that can effectively use the space above the swing arm. [0006] In order to solve the above-...
