20 rotary speed；Wheel hub 30, it is connected with decelerator 40, rotates wheel 10；Disk 100, it is connected with wheel hub 30；Braking
Pincers 50, it is configured at the outer peripheral face of disk 100, and to disk 100 pressure is applied, and produces brake force.
In the present embodiment, in-wheel motor 20 deviates the rotary shaft configuration of (offset) wheel 10, and in-wheel motor 20 is by car
Take turns 10 rotating shaft eccentric (offset) certain distance and configure and front is configured at by the longitudinal direction of vehicle.Thus, improve
The opposition side that in-wheel motor 20 deviates configures the degree of freedom of draft hitch.Also, caliper 50 can easily be configured at wheel 10
Wheel rim inside the deviation side of in-wheel motor 20 opposition side.
Referring to figs. 1 to Fig. 5, the in-wheel motor cooling system 1 of one embodiment of the invention is characterised by, including：Disk
100, it is configured with the disk cap 110 that a part of region of central part projects to outside；Air blast part 200, it can be in disk cap 110
Inner side rotatably configures, and produces cooling wind.
Disk 100 is configured between wheel 10 and wheel hub 30, by braking clamp body 50 apply pressure when, produce braking
Power.With reference to Fig. 3, a part of region of central part that the side combined with wheel is configured with disk 100 projects to the circle in outside
Disk cap 110.Wheel hub 30 and air blast part 200 are configured with the inner space of disk cap 110.
Also, with reference to Fig. 3 and Fig. 4, in the marginal area of disk cap 110 multiple air vents 111 are formed with.Air vent 111
Play a part of the passage that the inner side of disk cap 110 is flowed into as the moving air in the outside of wheel 10.
Air blast part 200 is configured between the wheel hub inner ring 31 of the inner side of disk cap 110 and wheel hub outer ring 32, also, with
Wheel hub inner ring 31 is combined and to be rotated with the speed same speed of wheel 10.
With reference to Fig. 5, air blast part 200 includes：Main part 210；Wheel hub joint portion 220, it is configured at the side of main part 210
Edge, is formed with wheel hub combined hole 221, also, is incorporated into wheel hub inner ring 31 by the bolt of wheel hub combined hole 221；Rotating vane

When air flow is come the condition for cooling down in-wheel motor 20, you can reach the purpose of the present invention.
That is, rotating vane 230 is configurable that cooling wind is formed from in-wheel motor 20 to the direction of disk cap 110.Thus, break
The air flow of inside wheel, makes that traveling wind is easy must to flow into inside wheel, thus, may achieve the purpose of the present invention.
Also, cooling pin 21 is configured with in-wheel motor 20, it is projected from the surface to the outside of in-wheel motor 20, and is dissipated
Send out the heat produced from in-wheel motor 20.Cooling pin 21 is effectively cooled down from wheel by the air sent from air blast part 200
The heat that motor 20 is produced.
To with this class formation in-wheel motor cooling system 1 effect carry out it is as described below.
By the driving of the system of in-wheel motor 20, when wheel 10 is rotated, the wheel hub 30 in combination with wheel 10 is carried out
Rotation.Disk 100 and air blast part 200 when wheel hub 30 rotates in combination with wheel hub 30 is rotated, by air blast part 200
Rotation produce to in-wheel motor 20 cooling wind.
Now, by being formed at the air vent 111 at the edge of disk cap 110 of disk 100, the air in the outside of wheel 10 is flowed into
Air blast part 200, also, leaked-in air blows to in-wheel motor 20 by air blast part 200.
Thus, in-wheel motor cooling system 1 of the invention, has the effect that, becomes without the need for carrying out other structure
More, the chiller of simple structure is configured inside wheel 10, you can effectively produce to the in-wheel motor 20 inside wheel 10
Cooling wind, thus, reduces the weight of in-wheel motor system and improves the simplicity of manufacturing process.
