A terminal box 68 and a signal terminal 69 (see FIG. 7) are provided on the upper surface of the motor 60, and a plurality of motor cables 75 extending from an inverter 70 are connected to the terminal box 68 and signal terminal 69. The inverter 70 is provided in front of the motor 60 and is located near the step board 23 (see FIG. 1). A battery 51, a motor 60, and an inverter 70, which are heavy objects, are installed near the center of the straddle-type vehicle 1, so that the center of gravity of the straddle-type vehicle 1 is brought closer to the center of the vehicle. Therefore, the rotational moment is reduced when the straddle-type vehicle 1 turns, and the steering stability of the straddle-type vehicle 1 is improved.

In this way, the battery 51 and the motor 60 are supported by the same bridge member 80, simplifying the structure of the vehicle body frame 10 and improving maintainability. Further, the battery 51 and the motor 60 are adjacent to each other in the vertical direction, and the motor 60 and the inverter 70 are adjacent to each other in the front-back direction. Since the inverter 70 is installed near the battery 51 and the motor 60, the battery cable 73 from the battery 51 to the inverter 70 is shortened, and the plurality of motor cables 75 from the inverter 70 to the motor 60 are shortened. Therefore, the wiring layout of battery cable 73 and motor cable 75 is simplified, wiring workability is improved, and wiring cost is reduced.

The wiring layout of electrical components will be described with reference to FIGS. 6 to 8. FIG. 6 is a perspective view of the motor seen from the right front. FIG. 7 is a plan view of the motor and inverter. FIG. 8 is a cross-sectional view of the motor and battery.

As shown in FIG. 6, the vicinity of the center of the bridge member 80 is parallel to the vehicle width direction, and the outside of the vicinity of the center of the bridge member 80 is inclined. A pair of battery brackets 81 are attached upward near the center of the bridge member 80, and a battery fixing portion 57 of the battery 51 is fixed to the tip of each battery bracket 81. A pair of motor brackets 82 are attached downward to the inclined portions at both ends of the bridge member 80, and a motor fixing portion 64 of the motor 60 is fixed to the tip of each motor bracket 82. In this way, the pair of motor brackets 82 on the lower side of the bridge member 80 are located on the outer side in the vehicle width direction than the pair of battery brackets 81 on the upper side of the bridge member 80.

Wiring routes for battery cables 73 and 74 are formed outside the pair of battery brackets 81 in the vehicle width direction. A battery cable 73 extending from the battery 51 to the inverter 70 is disposed on the outside of the left battery bracket 81 in the vehicle width direction. A battery cable 74 extending from the battery 51 to each electrical component of the straddle-type vehicle 1 is disposed on the outside of the right battery bracket 81 in the vehicle width direction. A plurality of cable holders 76 are installed on the outer surfaces of the battery 51 and the motor 60, and the battery cables 73 and 74 are held by the plurality of cable holders 76 so as to pass through a predetermined wiring route.

Wiring routes for a plurality of motor cables 75 are formed inside the pair of motor brackets 82 in the vehicle width direction. A pair of motor brackets 82, bridge member 80, and motor 60 form an opening that is long in the vehicle width direction, and a plurality of motor cables 75 from inverter 70 to motor 60 are passed through this opening side by side. Thereby, the bulge of the motor cable 75 when bent is suppressed to the inside of the opening. A plurality of cable holders 77 are installed on the outer surface of the motor 60, and the plurality of motor cables 75 are held by the plurality of cable holders 77 so as to pass through a predetermined wiring route.

In this way, the battery cables 73 and 74 pass above the bridge member 80, and the motor cable 75 passes below the bridge member 80, so that the wiring routes of the battery cables 73 and 74 and the motor cable 75 are vertically divided. has been done. Furthermore, since the battery cables 73 and 74 pass on the outside of the pair of battery brackets 81 and the motor cable 75 passes on the inside of the pair of motor brackets 82, the wiring routes of the battery cables 73 and 74 and the motor cable 75 are oriented in the left-right direction. It is sectioned. Therefore, when wiring the battery cables 73, 74 and the motor cable 75, the cables do not get entangled with each other, and the wiring work efficiency is improved.

As shown in FIG. 7, a plurality of (four) motor cables 75 extend from the inverter 70 toward the motor 60. Three motor cables 75 are connected to a terminal box 68 on the top surface of the motor 60, and the remaining one motor cable 75 is connected to a signal terminal 69 in front of the terminal box 68. The terminal box 68 and the signal terminal 69 are provided on the rear side of the rotation axis C of the motor 60 (see FIG. 8), and the connection ports of the terminal box 68 and the signal terminal 69 are directed to the left. Therefore, the motor cable 75 extends rearward from the inverter 70 toward the inside of the pair of motor brackets 82 in a plan view, and then curves rightward and is connected to the terminal box 68 and the signal terminal 69.

Further, as shown in FIG. 8, the plurality of motor cables 75 extend obliquely upward from the inverter 70 (see FIG. 7) toward the opening between the motor fixing part 64 and the bridge member 80 in a side view. It is curved diagonally downward and connected to the terminal box 68 and the signal terminal 69. At this time, the plurality of motor cables 75 bulge upward, but the bridging member 80 restricts the bulge of the plurality of motor cables 75 . Since the plurality of motor cables 75 are disposed along the upper surface of the motor 60 through the inside of the pair of motor brackets 82, consumption of the motor cables 75, which are expensive per unit length, is suppressed.

If the terminal box 68 and the signal terminal 69 are provided on the front side of the motor 60, the multiple motor cables 75 can be further shortened, but the terminal box 68 and the signal terminal 69 are provided on the step board 23 (see FIG. 1). A problem occurs in which the image looms upward. Therefore, in this embodiment, a terminal box 68 and a signal terminal 69 are provided directly below the battery 51 on the rear side of the rotation axis C of the motor 60. Even if the motor 60 is brought close to the step board 23, the terminal box 68 and the signal terminal 69 are prevented from protruding above the step board 23, thereby ensuring a wide footrest space on the step board 23.

As described above, according to this embodiment, the pair of rear frames 14 are located on both sides of the battery 51 and the motor 60, and the pair of rear frames 14 are connected via the bridge member 80, thereby increasing the rigidity of the vehicle body frame 10. and increased strength. The battery 51 is supported by the bridge member 80 via a pair of battery brackets 81, and the motor 60 is supported by the bridge member 80 via a pair of motor brackets 82. Since the battery 51 and the motor 60 are supported by the same bridge member 80 so as to be adjacent to each other, the structure and wiring layout of the vehicle body frame 10 are simplified. Maintainability and wiring workability are improved, and wiring costs between the battery 51 and the motor 60 are reduced.
