Fig. 3 is the Section A-A schematic diagram of the restraining coil assembly shown in Fig. 2；

Fig. 4 is the side view of the restraining coil assembly shown in Fig. 2.

First, the structure with reference to shown in Fig. 1-4, a kind of restraining coil assembly that the present embodiment provides, including the He of pedestal 41 At least two are arranged on the electromagnetic assembly 42 of described the same side of pedestal 41；The electromagnetic assembly 42 be for forming electromagnetic field, Active force, the application of fictitious load are formed with the principle using cutting magnetic induction line.

And the structure in such as Fig. 1 can be seen that the electromagnetic assembly 42 assembly method be its one end with it is described Pedestal 41 connects, and the other end of the electromagnetic assembly 42 is hanging, that is to say, that all electromagnetism groups being arranged on the pedestal 41 Part 42 is all the side for being located at the pedestal 41, rather than as in the prior art, the different correspondences of electromagnetic assembly 42 The both sides for being arranged on pedestal 41 in the form of forming electromagnetic field mutually.

, just will be adjacent after all electromagnetic assemblies 42 have been arranged on into the side of the pedestal 41 with continued reference to Fig. 1 The magnetic poles 422 of two electromagnetic assemblies 42 be reversed.

In one embodiment as shown in Figure 1, the electromagnetic assembly 42 is provided with five, and five electromagnetic assemblies 42 Be on the basis of the center of circle of pedestal 41, curved setting, distance phase of each electromagnetic assembly 42 apart from the center of circle of pedestal 41 Deng.

In this embodiment it is possible to there will be one end into the electromagnetic assembly 42 of the other end first, the 3rd and the 5th Electromagnetic assembly 42 is arranged to positive magnetic pole 422, second, the 4th electromagnetic assembly 42 be arranged to reverse magnetic pole 422 so that adjacent The magnetic poles 422 of two electromagnetic assemblies 42 be reversed.

Certainly, this is only a kind of embodiment set, can voluntarily set electromagnetism group as needed in practical set Quantity or magnetic pole 422 the collocation direction of part 42.

In addition, it should also be noted that, the south poles of electromagnetic assembly 42, which are set, can pass through the coil of electromagnetic assembly 42 Around realizing to the mode such as opposite or power-up sequence is opposite.

Fig. 8 is that the restraining coil assembly that the utility model one embodiment provides and the assembling structure of brake disc 43 are illustrated Figure；

Fig. 9 is that the restraining coil assembly that the utility model one embodiment provides and the operation principle of brake disc 43 are illustrated Figure.

And in the structure of the restraining coil assembly of the application, because all electromagnetic assemblies 42 have all been provided in pedestal 41 Side, so can not only allow restraining coil assembly fixed, and unilateral spatial has no constraint, can freely change Brake disc 43 and shafting componentses, to adjust and maintenance brings great convenience, compared with prior art, its structure is more ingenious, And the loading effect of load is also more good.

Wherein, it is preferred that the electromagnetic assembly 42 includes iron core 421, magnetic pole 422 and electromagnet coil 423；The electromagnetism Iron coil 423 is wrapped in the outer wall of iron core 421, and the magnetic pole 422 is arranged on the hanging one end of the iron core 421.This knot Structure is more prone to assemble and manufactured, but the structure of electromagnetic assembly 42 is not limited in this kind of structure to realize.

Additionally, it is preferred that, the iron core 421 is threadedly coupled by screw rod with the pedestal 41.

Likewise it is preferred that, the magnetic pole 422 is threadedly coupled by screw with the iron core 421.

As shown in figure 3, being assembled using screw rod or screw to electromagnetic assembly 42, namely utilize screw rod or screw pair Iron core 421 and pedestal 41 are threadedly coupled, and magnetic pole 422 and the memory of iron core 421 are threadedly coupled using screw rod or screw, can be more The assembling of convenient electromagnetic component 42, dismounting are all more prone to, operated also more flexible.

Further, it is preferred that 10mm gap is provided between two adjacent electromagnetic assemblies 42, reserves one Fixed gap, can making restraining coil assembly, caused electromagnetic field is more stable at work.
