As depicted in figs. 1 and 2, in the electric wheel hub automatic shift device of the present utility model, comprise rotating disk 1, first order inner gear 4 and depression bar 3, also comprise three breach 2, be mutually 120 ° of rectangular distributions between the breach 2, the shape of breach is that an end space is greater than the other end, one steel column 9 is arranged in the breach, adorn a spring 10 at the big sidewall of breach internal pore and withstand steel column 9, making steel column 9 be positioned at the little end in breach space and be ratchet shape projection 11 with depression bar 3 upper sections contacts, depression bar 3 is to be enclosed within on the rotating disk 1 near near the little axle 8 breach 2 small ends, and can sway; Three breach 5, also be mutually 120 ° of rectangular distributions between the breach, its shape also is that an end space is greater than the other end, one steel column 6 is arranged in the breach, adorn a spring 7 at the big sidewall of breach internal pore and withstand steel column 6, make steel column 6 be positioned at the little end in breach space and contact with the outside face of the first order inner gear 4 that is contained in rotating disk 1.
As shown in Figure 3 and Figure 4, depression bar 3 in the electric wheel hub automatic shift device of the present utility model, be bending, at a wide end one circular hole 12 is arranged, a narrow end is fixed a cylindrical little axle 13, between circular hole 12 and little axle 13 and near circular hole 12 1 ends be that the cross section is ratchet shape projection 11, projection 11 is opposite with little 13 direction of extension.
Fig. 5 and shown in Figure 6, fly to overlap 14 in the electric wheel hub automatic shift device of the present utility model, depression bar 3, have three breach 27 on the big end surfaces of the face area that flies to overlap 14, the degree of depth is greater than the thickness of depression bar 3, and they are mutually 120 ° of rectangular distributions, on breach 27, have one " U " shape groove 15, width is bigger slightly than the diameter of the little axle 13 of depression bar, and it points to the not center by flying to overlap, and groove 15 also is mutually 120 ° of rectangular distributions.Depression bar 3 is placed in the breach 27, and little axle 13 puts in the groove 15.
Fig. 7 and shown in Figure 8, the second stage inner gear 16 in the electric wheel hub automatic shift device of the present utility model, spring leaf 17; Have three mounting grooves 28 on the large internal gear 16 big internal circular surfaces, they are mutually 120 ° of rectangular distributions, and spring leaf just is inserted in the groove 28.
Shown in Figure 9, in the electric wheel hub automatic shift device of the present utility model, motor outer rotor 25, sun wheel 23, pinion carrier 21, rotating disk 1, fly to overlap 14, depression bar 3 and annulus 26, they are assembled together by motor shaft 22, pinion carrier 21 fixes with motor shaft 22; Three second stage satellite gears 20 (only drawing two) are installed on pinion carrier 21, second stage satellite gear 20 is intermeshing with the sun wheel 23 of central authorities, on each second stage satellite gear 20, be coaxially installed with a first order satellite gear 19, second stage satellite gear 20 interfixes with first order satellite gear 19, the diameter of first order satellite gear 19 is less than the diameter of second stage satellite gear 20, and first order satellite gear 19 is not meshing with each other with the sun wheel 23 of central authorities, the outside of first order satellite gear 19 is first order inner geares 4, be meshing with each other between them, all stepped rotating disk 1 inside and outside the outside of first order inner gear 4 is with one, between rotating disk 1 and first order inner gear 4 steel column 6 (totally three are only drawn two).What be with a certain angle free to rotate in motor outer rotor 25 outsides flies to overlap 14, the end that face area is big is contained in rotating disk 1 left side, (totally three of depression bars 3, only draw two) be contained in and fly to overlap (totally three of 14 breach 27, only draw one) in, fly to overlap 14 the other end and be with an annulus 26, fly to overlap 14 and annulus 26 between adorn a plane scroll spring 18, spring 18 two ends and the two are fixing respectively.Satellite gear 20 outsides in the second stage are second stage inner geares 16, intermesh between them, this grade gear is also stepped, studs with three spring leafs 17 (only drawing two) on its big internal circular surfaces, be enclosed within the jagged 2 (ends of totally three are only drawn one) of rotating disk 1 little outer round surface.Annulus 26 and rotating disk 1 outside are fixing with wheel hub shell 24.
Motor outer rotor 25 drives sun wheel fixed thereon 23 and rotates, because sun wheel 23 is meshing with each other with second stage satellite gear 20, therefore the two-stage satellite gear that interfixes also rotates together, first order satellite gear 19 is meshing with each other with first order inner gear 4, second stage satellite gear 20 is meshing with each other with second stage inner gear 16, but because the internal diameter of first order inner gear 4 is less than the internal diameter of second stage inner gear 16, so the rotating speed of first order inner gear 4 is slower than the rotating speed of second stage inner gear 16, because the steel column 6 in rotating disk 1 three breach 5 of little internal circular surfaces (not drawing among the figure) contacts with the smooth outside face of first order inner gear 4 under the effect of spring 7 (not shown)s, and (totally three of steel columns 9 in three breach of rotating disk 1 little outer round surface 2, only draw one) be subjected to the compressing that cross section on the depression bar 3 is ratchet shape projection 11, disengage with the spring leaf 17 on the second stage inner gear 16 big internal circular surfaces, this is equivalent to second stage inner gear 16 in idle running.When automatic shift device reaches the setting rotating speed, fly to overlap 14 under action of centrifugal force, the resistance that overcomes plane scroll spring 18 rotates, simultaneously by " U " shape groove in three breach 27 15 (totally three, only drawing one) sidewall acts on little axle 13, driving depression bar 3 lifts, release is to the compressing of steel column 9, thereby make steel column 9 get back to the little end in rotating disk 1 breach 2 spaces, realize steel column 9 and speed contacting of the spring leaf 17 on the second stage inner gear 16 faster, rotating disk 1 is speeded up, simultaneously slow-footed first order inner gear 4 is realized overdrive clutch with the steel column 6 in the rotating disk 1 little internal circular surfaces breach 5, because rotating disk 1 wheel hub 24 with annulus 26 external fixation, cause wheel hub 24 speed-raisings again.When resistance increases, when speed reduces, when second stage inner gear 16 is not enough to the speed of maintenance itself, spring leaf 17 oppressed distortion on it disengage by force with steel column 9, simultaneously, fly to overlap 14 under the effect of volute spiral spring 18, get back to initial position, and drive little axle 13 and put down depression bar 3, force steel column 9 and spring leaf 17 on the second stage inner gear 16 to disengage fully.This sample automatic shift device is finished the auto-update and the degradation of speed.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; also can make some modification and improvement, these also should be considered as protection domain of the present utility model.
