Please refer to Fig. 1, a kind of magnet controlled moment induction driving system that the utility model provides comprises: motor; Drop-gear box, sprocket wheel 8, the first mono-directional overrun clutchs 10, axis 11; Driving disc spacing pressing 18, clutch plate 19, the first Hall elements 12; Second hall sensor, 13, the second mono-directional overrun clutchs etc. 1.
Said drop-gear box comprises center external gear 2, center inner gear 7, planetary wheel 6 and pinion carrier 17; Said pinion carrier 17 is captiveed joint with the shell 5 of said motor; Said center inner gear 7 one ends are captiveed joint with the shell 5 of said motor; The other end is captiveed joint with the outer shroud and the sprocket wheel 8 of the said first mono-directional overrun clutch 10, and said planetary wheel 6 is engaged between said center inner gear 7 and the center external gear 2.
Said motor comprises rotor 4, motor coil 3 and hollow shaft 9; Said rotor 4 output torques also pass through second overdrive clutch, 1 drive hollow shaft 9 and rotate; The said center of said hollow shaft 9 rotating drive external gear 2; Through the deceleration of said planetary wheel 6 and said center inner gear 7, output power drives said sprocket wheel 8.
Along the circumferential direction settle a circle power-assisted magnet steel 20 on the driving disc spacing pressing 18, form the first power-assisted magnet ring 13, the also corresponding arrangement one circle power-assisted magnet steel 20 of clutch plate 19 forms the second power-assisted magnet ring 14.And both magnet steel quantity is identical; Wherein driving disc spacing pressing 18 and clutch plate 19 are through slip draw-in groove and elastomeric element 16; Fit mutually like tensioning spring, under initial condition, the first power-assisted the magnet ring 13 and second power-assisted magnet ring 14 is as shown in Figure 3 radially agrees with; And the magnetic pole of a series of magnet steel 20 of the first power-assisted magnet ring 13 and the second power-assisted magnet ring, 14 the insides is corresponding one by one; Driving disc spacing pressing 18 is fixedly mounted on the axis 11, and the interior ring of the clutch plate 19 and the first individual event overdrive clutch 10 is installed on the same axle, the outer shroud of the first mono-directional overrun clutch 10 and sprocket wheel 8 fixed installations.First Hall element 12 and second Hall element 15 and motor housing 5 relative fixed, and the sensitive surface of two Hall elements is respectively facing to first power-assisted magnet ring 13 on the driving disc spacing pressing 18 and the second power-assisted magnet ring 14 on the clutch plate 19.
As shown in Figure 2; As a kind of distortion; Said driving disc spacing pressing 18 is fixedly installed on the said axis 11 through the first mono-directional overrun clutch 10; The interior ring of the said clutch plate 19 and the second mono-directional overrun clutch 19 is fixedly installed on the said axis 11 jointly, and said driving disc spacing pressing 18 is fitted mutually through elastomeric element 16 with clutch plate 19, and the outer shroud of the said second mono-directional overrun clutch 1 is captiveed joint with said center inner gear one side; Said driving disc spacing pressing 18 along the circumferential direction is equipped with the first power-assisted magnet ring 13, and said clutch plate 19 along the circumferential direction is equipped with the second power-assisted magnet ring 14, and the said first power-assisted magnet ring 13 and the second power-assisted magnet ring 14 radially agree with; The sensitive surface of said first Hall element 12 and second Hall element 15 is relative with the second power-assisted magnet ring 14 with the said first power-assisted magnet ring 13 respectively.After this kind distortion is transferred to drop-gear box output with second mono-directional overrun clutch 1 from hollow shaft 9; Can control the volume of whole motor; And manpower can not drive the drop-gear box transfer when driving, and correspondingly, the first mono-directional overrun clutch, 10 positions also move between axis 11 and the driving disc spacing pressing 18.
A kind of magnet controlled moment induction driveline principle that the utility model provides: like Fig. 3 and shown in Figure 4, under the initial condition, when just manpower is not paid attention to stretcher; The angle A of cooresponding a pair of magnet steel 20 relative certain basic point is identical with angle B on driving disc spacing pressing 18 and the clutch plate 19, and when the needs Electrical Bicycle was power-assisted, manpower was stepped on stretcher; Axis 11 rotates, and drives driving disc spacing pressing 18 and rotates, at this moment; Driving disc spacing pressing 18 compression springs 16 send torsion to clutch plate 19 simultaneously, and driving disc spacing pressing 18 reverses certain angle relatively with clutch plate 19, and (two groups of magnet rings produce relative displacement; As shown in Figure 4; Angle A is greater than angle B), and driving disc spacing pressing 18 is applied on the sprocket wheel 8 through the first mono-directional overrun clutch 10 with clutch plate 19, orders about bicycle and moves ahead.At this moment; Driving disc spacing pressing 18 and clutch plate 19 are all in high speed rotating, and the circle of one on driving disc spacing pressing 18, the clutch plate 19 magnet steel 20 is at a high speed through after two Hall element sensitive surface, and two Hall elements are just exported a series of square-wave signal respectively; Because the torsion that pin is stepped on causes driving disc spacing pressing 18, clutch plate 19 to reverse certain angle relatively; Angle A is greater than angle B, so the square-wave signal on the driving disc spacing pressing 18 will be ahead of the square-wave signal on the clutch plate 19, these two groups of phase place different pulse signals are after amplifying calculating; According to phase difference size output corresponding control current, press design-calculated proportional control motor output drive strength.It is big more to that is to say that manpower drives, and the relative displacement of the magnet steel 20 in two groups of magnet rings is big more, and the phase difference of two group pulses is big more, and the propulsive effort of motor output is big more so, and motor-driven and manpower driving and generating superpose like this, thereby have reached real power-assisted purpose.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; If do not break away from the spirit and the scope of the utility model, the utility model is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
