In figure: wheel spoke 1, just taken turns 2, flexbile gear 3, flexible bearing 4, cam structure wave producer 5, electric machine main shaft 6, rotor 7, permanent magnet 8, stator 9, bearing assembly 10.
The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail, and object is only to understand better the utility model content.Therefore, the cited case does not limit protection domain of the present utility model.
Referring to Fig. 1, Fig. 2, this harmonic wave reducing motor drive hub device that the present embodiment provides, is mainly comprised of wheel hub motor and harmonic speed reducer two parts, wherein:
Wheel hub motor adopts the version of internal stator outer rotor, and stator 9 and stator winding integral body thereof are fixed on electric machine main shaft 6, and rotor 7 is assemblied on electric machine main shaft 6 by bearing assembly 10, and permanent magnet 8 is embedded on the interior lateral body of rotor 7 corresponding to stator winding.
Harmonic speed reducer is by cam structure wave producer 5, flexible bearing 4, flexbile gear 3 and just taken turns 2 and form, cam structure wave producer 5 is ellipsoid, ellipsoid fixes as one by the outer lateral body of its center circle and rotor 7, on ellipsoid, be set with flexible bearing 4 and by flexible bearing 4, oval flexbile gear 3 be housed, the outer cover of oval flexbile gear 3 is equipped with circular just wheel 2, the outer ring tooth engagement of the internal ring gear of circular just wheel 2 and oval flexbile gear 3, circular just wheel 2 ectosomes are fixedly connected with wheel spoke 1.
When electronlmobil will move, the autogamy power supply of electronlmobil by wire harness to the stator winding electrifying in wheel hub motor, the permanent magnet 8 being fixed on rotor 7 after energising rotates under the effect of electromagnetic force, and then drives the rotor 7 being installed on electric machine main shaft 6 by bearing assembly 10 to move.Because rotor 7 is one with cam structure wave producer 5, the motion of rotor 7 drives cam structure wave producer 5 to rotate, cam structure wave producer 5 passes motion to flexbile gear 3 by coupled flexible bearing 4, flexbile gear 3 drives just wheel 2 runnings by gear transmission mode, last just wheel 2 drives wheel spoke 1 motion of coupled electronlmobil, and then drives whole electronlmobil wheel to rotate.
Said structure takes full advantage of the small space between electronlmobil spoke and Wheel hub motor external rotor, and harmonic speed reducer is reasonably satisfied with in this space, makes the utlity model has compact conformation, volume is little, driving efficiency is high, kinematic accuracy advantages of higher.
