Fig. 2 illustrates the assembling schematic diagram of magnetic field device according to an embodiment of the invention, wherein eliminates the housing 140 for holding transmission device II.As shown in Figure 2, the clutch yoke 128 in transmission device II can go to the state being separated with the first gear 121 or contacting with the first gear 121 as required, respectively corresponding first mode and the second pattern.In transmission device II, 3rd gear 123 and the 4th gear 124 form in-line gears structure, namely the 3rd gear 123 axle center is connected by steering spindle 129 with the 4th gear 124 axle center, preferably the 3rd gear 123 is connected with motor 100 for driving wheel, by the transmission of steering spindle 129, the 4th gear 124 is followed the 3rd gear 123 as driven pulley with equidirectional same angular speed and is rotated together.First gear 121, first connecting axle 135 is coaxial with the first magnet ring 131, wherein the first connecting axle 135 top is connected with the first magnet ring 131 bottom, first connecting axle 135 lower part is connected with the first gear 121, and the first magnet ring 131 is rotated with the first gear 121 by the drive of the first connecting axle 135.Meanwhile, the first gear 121 can move up and down along axis, and be separated with under the state contacted at clutch yoke 128 and the first gear 121, the first gear 121 can move to primary importance A and second place B respectively; Second gear 122, second connecting axle 136 is coaxial with the second magnet ring 132, wherein the second connecting axle 136 top is connected with the second magnet ring 132 bottom, second connecting axle 136 lower part is connected with the second gear 122, and the second magnet ring 132 is rotated with the second gear 122 by the drive of the second connecting axle 136.Meanwhile, the second gear 122 and the 4th gear 124 to be in same plane and to be engaged with each other, and the second gear 122 rotates with the 4th gear 124 as driven pulley.The 5th gear 125 is provided with between the first gear 121 and the 3rd gear 123, when clutch yoke 128 is in the first gear 121 released state, first gear 121, the 5th gear 125 and the 3rd gear 123 are in same plane, and the 5th gear 125 engages with the first gear 121 and the 3rd gear 123, the 5th gear 125 as idle pulley by the Movement transmit of the 3rd gear 123 to the first gear 121; When clutch yoke 128 and the first gear 121 contact condition, the first gear 121 moves to second place B along on axle, staggers with the 5th gear 125.Wherein, the ratio of the radius of the first gear 121 and the 3rd gear 123 equals the ratio of the radius of described second gear 122 and described 4th gear 124.The gear teeth of the 7th gear 127 and the 6th gear 126 are located on end face, and the two gear teeth is oppositely arranged.7th gear 127 and the second gear 122 be coaxial to be connected and to be located at the lower surface place of the second gear 122, rotates with the second gear 122; 6th gear 126 and the first gear 121 be coaxial to be connected and to be located at the upper surface place of the first gear 121, and the two rotates simultaneously.When clutch yoke 128 contacts with the first gear 121, first gear 121 moves to second place B, first gear 121 drives on the 6th gear 126 and moves, 6th gear 126 is engaged with the 7th gear 127, the 6th gear 126 can be driven to rotate together when the 7th gear 127 rotates, under this state, the first gear 121 rotates with the 6th gear 126 as driven pulley; When clutch yoke 128 is separated with the first gear 121, the first gear 121 moves to primary importance A, and the 6th gear 126 moves with the first gear 121 thus is separated with the 7th gear 127, and under this state, the 6th gear 126 rotates with the first gear 121 as driven pulley.In addition, as shown in Figure 1, transmission device II also can be provided with housing 140 outward, extraneous things can be prevented the impact of transmission device II, also the accidental injury that transmission device II operationally may cause to external world can be prevented, the simultaneously setting of housing 140 makes outside transmission device II is not directly exposed to, to add the attractive in appearance of whole device.
The rotation schematic diagram of first mode as shown in Figure 3.When clutch yoke 128 is in the first gear 121 discontiguous state, the first gear 121 is in primary importance A, engages with the 5th gear 125.In running order motor 100 drives the 3rd gear 123 to rotate, with coaxial the 4th gear 124 of the 3rd gear 123 thereupon together with rotate, because the 3rd gear 123 and the 4th gear 124 are coaxial gears, turning to and the identical (ω of angular speed of the two
3=ω
4); The 5th gear 125 engaged with the 3rd gear 123 passes motion to the first gear 121 as idle pulley, because the 5th gear 125 only plays transmission effect, and therefore the turning to and linear velocity υ of the first gear 121
