Further, the outside of said first outer rotor bearing and/or second outer rotor bearing also is provided with oil sealing.
Further, the periphery of external rotor body connects screw through wheel and removably is connected with wheel hub, is arranged with tire on the said wheel hub.
Further, said outer rotor generator also includes the brake of electroplax formula, is arranged on the said driven axletree, in order to brake said external rotor.
According to outer rotor generator of the present invention; The kinetic energy of driven pulley in the time of can effectively utilizing running car and generating electricity reasonably converts mechanical energy to electric energy, further to automobile auxiliary electric energy is provided; Avoided wasting of kinetic energy; Simple in structure, the science environmental protection is so possess practicality widely.Meanwhile, removably connect owing to adopt between external rotor and the wheel hub, make that outer rotor generator easy accessibility of the present invention, maintenance process obtain simplifying, and prolonged its useful life effectively, economy is preferable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.Wherein:
Fig. 1 is the structural representation of electrocar outer rotor generator of the present invention;
Fig. 2 is the decomposing schematic representation of electrocar outer rotor generator of the present invention; And
Fig. 3 is the end view of the external rotor body of electrocar outer rotor generator of the present invention.
Embodiment
Below, through exemplary execution mode the present invention is specifically described.Yet should be appreciated that under the situation that is not having further narration element, structure and characteristic in execution mode also can be attached in other execution mode valuably.
Consult Fig. 1; It shows according to a kind of electrocar outer rotor generator 10 of the present invention; Be arranged on the driven pulley of said electrocar, wherein said outer rotor generator 10 includes: internal stator 11 is fixedly connected on the driven axletree 20 of said electrocar; And external rotor 12, be rotatably connected on the driven axletree 20 of said electrocar, and be set in the outside of said internal stator 11.Wherein, also include many cover winding coils 31 on the said internal stator 11, said many cover winding coils 31 are arranged on the peripheral part of internal stator 11; Also be provided with a plurality of permanent magnets 32 on the said external rotor 12, said a plurality of permanent magnets 32 are distributed on predetermined space on the inner tube wall of external rotor 12, with as rotating magnetic field.When said external rotor 12 rotates with respect to said internal stator 11, produce the cutting magnetic induction line motion between winding coil 31 and the permanent magnet 32, thereby produce electric energy according to electromagnetic induction principle.Be, the number of above-mentioned permanent magnet and winding coil is not unique with being to be understood that, can export permanent magnet and the winding coil that what different demands of electric energy are provided with the phase suitable number according to reality.
In conjunction with shown in Figure 2, for the ease of processing and fabricating and installation, said external rotor 12 also comprises: external rotor body 121 is connected on the said driven axletree 20 through first outer rotor bearing 41, and is positioned at the outside of said internal stator; And external rotor cover plate 122, be connected on the said driven axletree 20 through second outer rotor bearing 42, and be positioned at the inboard of said internal stator.Optional is, adopts engaging to be connected between said external rotor body 121 and the said external rotor cover plate 122, with the reliability and stability of the annexation between assurance external rotor body 121 and the external rotor cover plate 122.Owing to the effect of first outer rotor bearing 41 and second outer rotor bearing 42, can guarantee the smooth and easy nature of rotation of external rotor 12, safe and reliable.
