＜ arrestment mechanisms ＞

Next, reference picture 2, Fig. 4 and Fig. 5 are illustrated to the arrestment mechanism of driver element 1.Fig. 4 is to show first The plan of a part for the driver element 1 of implementation method, Fig. 5 is a part for the driver element 1 for showing first embodiment Amplification view.Here, Fig. 2 and Fig. 5 show that motor part 2 does not drive, and it is braked the state of the braking of portion 5.The opposing party Face, Fig. 4 shows that motor part 2 drives, and is not braked the state of the braking of portion 5.

First, the state to Fig. 2 is illustrated.In fig. 2, elastomeric element 544 is in the longitudinal direction with than in zero load The short state of length be kept.More specifically, elastomeric element 544 is helical spring, and the helically length side of spring To the length state shorter than the natural length of helical spring.Also, electric current is not by the solenoid in solenoid unit 542, From without producing magnetic attraction between magnetic 541 and solenoid unit 542.Therefore, elastomeric element 544 can mover by first 51 towards paper right side press, and by second can mover towards paper left side press.In addition, in elastomeric element 544 by spiral bullet In the case that part beyond spring is constituted, as long as using the construction and device that can realize following this mechanism：Elastic portion Part 544 by first can mover 51 towards paper right side press, and by second can mover 52 towards paper left side press.

On the other hand, first can mover 51 and second can mover 52 be supported to respectively can be relative to first connecting portion 32 Swing.Therefore, first can mover 51 pressed by by elastomeric element 544, so as to first connecting portion 32 be fulcrum diametrically Interior side oscillation is radially oriented from the outside of rotor retainer 211, and is contacted with the outer surface 213 of cylindrical portion.Second can mover 52 Pressed by by elastomeric element 544, and with first connecting portion 32 be fulcrum diametrically from the outer lateral footpath of rotor retainer 211 Inside side oscillation, and contacted with the outer surface 213 of cylindrical portion.That is, first can mover 51 can mover 52 this two side with described second Abutted with the outer surface 213 of cylindrical portion.Thereby, it is possible to the rotation in brake motor portion 2.In the present embodiment, first can mover 51 and second can mover 52 by from radial outside press outer-rotor type rotor portions 21 come the rotation in brake rotors portion 21.By This, compared with the situation of the rotor portions of pressing inner-rotor type, due to rotor portions can be pressed at the position for leaving central axis J 21, therefore, it is possible to increase the torque for brake rotors portion 21, and rotor portions 21 can be more efficiently reduced in central axis J Moment of momentum on direction.

In the present embodiment, in the case where the electric current for driving is not provided to motor part 2, solenoid list is not also given Unit 542 provides electric current.Therefore, above-mentioned arrestment mechanism is realized when motor part 2 does not rotate, therefore, it is possible to higher with reliability The rotation in state brake motor portion 2.

First can mover 51 and second can mover 52 each have contact component.The outer surface of contact component and cylindrical portion 213 abut.Contact component is made up of the first contact site C1 and the second contact component C2.More specifically, first can mover 51 With the first contact site C1, second can mover 52 there is the second contact component C2.First contact site C1 and the second contact component C2 Each abutted with the outer surface 213 of cylindrical portion.Thus, with first can mover 51 and second can mover 52 without contact component Situation is compared, and is capable of the rotation in more reliably brake motor portion 2.In addition, contact component is preferably the part of rubber system.Thus, Can by cheap material increase first can mover 51 and second can make between mover 52 and the outer surface 213 of cylindrical portion Frictional force, therefore, it is possible to improve braking function at low cost.But, contact component can also be formed by other materials.

Next, being illustrated to the state of Fig. 4.In fig. 4, by providing the electric current of driving to motor part 2, so that Rotor portions 21 are rotated by the magnetic force acted between the magnetic field and rotor magnet 214 that coil is produced by electric current.The opposing party Face, when electric current is provided to motor part 2, electric current is also provided to solenoid unit 542.Now, electric current still flows to configuration in helical The solenoid of the inside of pipe unit 542, so as in solenoidal internal generation magnetic field.Therefore, in magnetic 541 and solenoid list Magnetic attraction is produced between unit 542, so as to be attracted one another on the basis of the state of Fig. 2.At the same time, fixed with magnetic 541 First together can mover 51 towards paper left side swing, second be fixed together with solenoid unit 542 can mover 52 Swung towards paper right side.

First can mover 51 and second can mover 52 with above-mentioned swing, with first connecting portion 32 as fulcrum, respectively from The outer surface 213 of cylindrical portion swings to radial outside, and leaves the outer surface 213 of cylindrical portion.Also, can mover 51 by first A part for paper left surface abut with the paper right flank of second connecting portion 33, second can mover 52 paper right flank A part is abutted with the paper left surface of second connecting portion 33, thus first can mover 51 and second can the swing of mover 52 stop Only.Thus, motor part 2 is in the state not abutted with braking parts 5, so that motor part 2 is changed into rotating.

Next, to first can mover 51 and second can the relation of mover 52 and second connecting portion 33 carry out specifically It is bright.Reference picture 2 and Fig. 5, when motor part 2 does not rotate, first can mover 51 and second can mover 52 respectively with the second projection Portion 33 is opposite across gap.More specifically, gap includes the first clearance D 1 and the second clearance D 2.That is, orthogonal to the axial direction Direction on, first can mover 51 and second connecting portion 33 it is opposite across the first clearance D 1, second can the projection of mover 52 and second Portion 33 is opposite across the second clearance D 2.

Next, reference picture 4, when motor part 2 rotates, first can mover 51 and second can mover 52 it is prominent with second respectively Portion 33 is played to abut.Thus, by appropriate adjustment the first clearance D 1 and the second clearance D 2, can by first can mover 51 and second can The movable range of mover 52 is adjusted in preferred scope.In addition, in the present embodiment, the first clearance D 1 and the second clearance D 2 And equal to produce magnetic attraction so as to actuating unit 54 drive when magnetic 541 it is relative with solenoid unit 542 Displacement.

Reference picture 4, the first imaginary line L1 is the imaginary line of center by first connecting portion 32 and central axis J.Such as Fig. 4 Shown, when overlooking, at least a portion of magnetic 541 is Chong Die with the first imaginary line L1.Thereby, it is possible to make first as much as possible The power of the power of the outer surface 213 of contact site C1 pressing cylindrical portions and the outer surface 213 of the second contact component C2 pressing cylindrical portions is equal Deng.That is, can by by first can mover 51 and second can mover 52 bear the application point of the power from elastomeric element 544 in On the basis of heart axis J, configuration with as first can mover 51 and second can mover 52 swing fulcrum first connecting portion On 32 symmetrical directions such that it is able to by first can mover 51 and second can mover 52 be applied to the outer surface 213 of cylindrical portion Power is symmetrical close to line on the basis of the first imaginary line L1.Therefore, the precision during rotation in brake rotors portion 21 is improved.

Also, as shown in figure 4, when overlooking, at least a portion of second connecting portion 33 is Chong Die with the first imaginary line L1.By This, can by first can mover 51 circumferential lengths with second can mover 52 circumferential lengths be set to as much as possible it is equal.Cause This, can on the basis of the first imaginary line L1, be applied to as much as possible first can mover 51 stress be applied to second can The stress of mover 52 is impartial.That is, therefore, it is possible to suppress to first can mover 51 and second can be in mover 52 any one apply big Stress.

Also, reference picture 5, the first clearance D 1 is with the second clearance D 2 apart from roughly equal.Thereby, it is possible to make first can mover 51 with second can mover 52 movable range it is roughly equal.Accordingly, with respect to the first imaginary line L1, can make first can mover 51 Opportunity for being abutted with the outer surface 213 of cylindrical portion to the greatest extent can may be used on the opportunity that is abutted with the outer surface 213 of cylindrical portion of mover 52 with second Energy ground is consistent such that it is able to the accurately rotation in brake rotors portion 21.

Reference picture 4, when overlooking, contact component only configures and the position of the side of first connecting portion 32 is being leaned on than central axis J.More For in detail, when overlooking, using by central axis J and the imaginary line orthogonal with the first imaginary line L1 as the second imagination During line L2, the first contact site C1 and the second contact component C2 is only configured where than the second imaginary line L2 by first connecting portion 32 Region.Can mover 51 and as first thereby, it is possible to being located proximate to of making contact component be contacted with the outer surface 213 of cylindrical portion Two can mover 52 swing when fulcrum first connecting portion 32.Therefore, according to lever principle, even if acting on magnetic 541 In the case of less strong with the magnetic attraction of solenoid unit 542, it is also possible to increase the appearance that contact component presses cylindrical portion The power in face 213.Also, it is preferred that the first contact site C1 and the second contact component C2 is in symmetrical position relative to the first imaginary line L1 Put.Thereby, it is possible to the first contact site C1 and the second contact component C2 to be pressed the possibly phase that overcomes of the outer surface 213 of cylindrical portion It is symmetrical for the first imaginary line L1.

Fig. 6 is the side view of braking parts 5 and basal part 3.Reference picture 6, at least a portion of solenoid unit 542, magnetic At least a portion of body 541, at least one of axial height of elastomeric element 544 is identical.I.e., in the axial direction, solenoid 542nd, magnetic 541 and elastomeric element 544 have the region for overlapping.Thereby, it is possible to reduce the axial direction of actuating unit 54 Highly.

Pedestal portion 34 extends from basal part 3 towards axially upside.That is, basal part 3 has towards the platform that axially upside extends Portions 34.The general planar of upper surface 341 of pedestal portion.The upper surface 341 of pedestal portion with second can the lower surface of mover 52 contact. But, the upper surface 341 of pedestal portion with second can the lower surface of mover 52 be not fixed together, and can relatively slide.The Two can the upper surface 53 of mover 52 be fixed together with the lower surface 543 of solenoid unit 542.Thus, even if to solenoid In the case that unit 542 applies towards load axially below, solenoid unit 542 also in the axial direction can mover 52 by second Hold, second can mover 52 also supported by pedestal portion 34 in the axial direction.Therefore, even if movable to solenoid unit 542 and second In the case that son 52 applies towards load axially below, it is also possible to which high reliability supporting solenoid unit 542 and second can Mover 52.

The upper surface 341 of pedestal portion with second can mover 52 can slidably abut.Thus, when in magnetic 541 and spiral shell Between spool unit 542 produce magnetic attraction when, second can mover 52 be integrally formed with solenoid unit 542 such that it is able to court Slided to paper right side.In addition, the upper surface 341 of pedestal portion may not necessarily general planar, or other shapes.Now, As long as a part for pedestal portion 34 with second can the part of mover 52 can slidably abut.
