This kind of abversion minor in -wheel motor, including the wheel main part, wheel main part inner wall is equipped with the motor rotor, and the motor stator is installed at wheel main part center, the motor rotor overcoat is equipped with motor winding, is equipped with the permanent magnet between motor rotor and wheel main part inner wall, the motor stator is connected with the brake drum, the integrated into one piece of wheel main part outward flange department has the spoke, and the tire is installed outward to the spoke. The utility model discloses simple structure, reasonable in design need not gear change drive mechanism, and its motor rotor direct mount is inboard at the rim of wheel main part, can remove speed change gear completely, and motor speed and wheel speed equal that the rotary speed control of motor is depended on completely in wheel speed and speed of a motor vehicle control.
Description
Technical field
The utility model relates to wheel hub motor technical field, especially a kind of external-rotor-type wheel hub motor.
Background technology
For conventional truck, power-transfer clutch, change-speed box, transmission shaft, diff and even part-time case are all absolutely necessary, and these parts not only weight light, make the structure of vehicle more complicated, also there is the problem needing periodical maintenance and fault rate simultaneously.But wheel hub motor just solves this problem well.Wheel hub motor technology is also known as wheel inner electric machine technology, and power, transmission and brake equipment are all incorporated in wheel hub by its maximum feature exactly, are therefore greatly simplified by the mechanics of elec. vehicle.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of external-rotor-type wheel hub motor.
The utility model solves the technical scheme that its technical matters adopts: a kind of external-rotor-type wheel hub motor, comprises wheel body, and wheel body inwall is provided with motor rotor, and wheel body center is provided with motor stator; Be arranged with electrical motor winding outside described motor rotor, between motor rotor and wheel body inwall, be provided with permanent magnet; Described motor stator is connected with brake wheel; Described wheel body outer edge is one-body molded spoke, is provided with tire outside spoke.
Further, bearing is provided with between described brake wheel and motor stator.
Further, described motor stator is built-in with coder.
Further, described bearing is ball bearing of main shaft.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, without the need to speed-changing gear driving device, its motor rotor is directly installed on inside the wheel rim of wheel body, transmission system can be removed completely, motor speed is equal with vehicle wheel rotational speed, and vehicle wheel rotational speed and the speed of a motor vehicle control to depend on completely that the rotating speed of electrical motor controls.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. tires, 2. spoke, 3. permanent magnet in figure, 4. electrical motor winding, 5. wheel body, 6. brake wheel, 7. bearing, 8. coder, 9. motor stator, 10. motor rotor.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
External-rotor-type wheel hub motor as shown in Figure 1, comprises wheel body 5, and wheel body 5 inwall is provided with motor rotor 10, and wheel body 5 center is provided with motor stator 9; Be arranged with electrical motor winding 4 outside motor rotor 10, between motor rotor 10 and wheel body 5 inwall, be provided with permanent magnet 3; Motor stator 9 is connected with brake wheel 6; Wheel body 5 outer edge is one-body molded spoke 2, is provided with tire 1 outside spoke 2.
Bearing 7 is provided with between brake wheel 6 and motor stator 9; Motor stator 9 is built-in with coder 8; Bearing 7 is ball bearing of main shaft.
This external-rotor-type hub motor structure is simple, reasonable in design, without the need to speed-changing gear driving device, its motor rotor 10 is directly installed on inside the wheel rim of wheel body 5, transmission system can be removed completely, motor speed is equal with vehicle wheel rotational speed, and vehicle wheel rotational speed and the speed of a motor vehicle control to depend on completely that the rotating speed of electrical motor controls.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
