Description of the drawings

Fig. 1 is the structural representation of this utility model clutch drive.

Specific embodiment

Specific implementation method of the present utility model is as follows：

Be illustrated in figure 1 the structural representation of this utility model clutch drive, wherein 1 be axis, 2 be outer tube, 3 For inner core, 4 are magnet, 5 are copper coil, the axis 1 is fixedly connected or the axis 1 and the outer tube 2 with the outer tube 2 Integrated setting, the outer tube 2 may be designed as tubular structure with the inner core 3, can be cylindric or square tube shape structure, institute It is hollow-core construction to state outer tube 2 and the inner core 3, and one end end-cover-free of the outer tube 2 and the inner core 3, the other end have end cap, institute State axis 1 and connect the end cap of the outer tube 2 inner side centre position, the inner core 3 is placed in the inside of the outer tube 2 and the inner core 3 Outwardly, the inner core 3 is placed on the axis 1 end cap, and the inner core 3 is not contacted with the outer tube 2, axis 1, the inner core 3 end cap outside connection clutch actuating mechanism.

The magnet 4 is set on the inwall of the outer tube 2, the copper coil 5, the magnetic are wound on the outer wall of the inner core 3 Body 4 is correspondingly arranged with the copper coil 5, in order to form more preferable magnetic field effect, magnet knot can also be arranged on the axis 1 Structure, coordinates the magnet 4 to form magnetic field.

The axis 1 is permeability magnetic material with the outer tube 2, and the inner core 3 is non-magnet material, and the copper coil 5 connects One power supply, the electric current by needed for the power supply provides the copper coil 5.

If length B1 of the magnet 4 and thickness B2 are too little, its magnetic field intensity is not enough, can cause the driving force for producing Deficiency, is unsatisfactory for clutch demand, thus, it is described in the requirement for meeting clutch drive demand and material-saving as far as possible Length B1 of magnet 4 and the preferred span of thickness B2 are：15mm≤B1≤100mm, 2mm≤B2≤10mm.

The thickness C1 of the outer tube 2 not only has influence on its intensity, and because the outer tube 2 is the magnetic conduction of the magnet 4 Path, thus, the thickness C1 of the outer tube 2 also contributes to the magnetic flux of the magnet 4, and this utility model is considering the outer tube After 2 intensity, the magnetic flux of the magnet 4 and material-saving, the preferred scope for providing the thickness C1 is：6mm≤C1≤ 16mm。

Length A1 and thickness A 2 of the copper coil 5 also contribute to the size of driving force, if length A1 of the copper coil 5 And thickness A 2 is too small, driving force can be caused not enough, and with driving executing mechanism of clutch during, the copper coil 5 Can move, if length A1 is not enough, the movable distance of the copper coil 5 can be caused shorter, clutch certainly will be had influence on Stroke, its performance is affected then, thus, in view of after clutch performance, this utility model provides the length of the copper coil 5 Degree A1 and the preferred scope of thickness A 2 are：20mm≤A1≤120mm, 2mm≤A2≤10mm.

When clutch needs action, the power supply is powered to the copper coil 5, because electrical conductor can be received in magnetic field To the effect of power, the active force is the driving force for driving the copper coil 5 and the movement of the inner core 3, drive then it is described from Clutch actuator campaign, realizes clutch function；When clutch does not need action, the power supply is disconnected, now without magnetic field Active force, the copper coil 5 and the meeting homing in the presence of clutch spring of inner core 3.

Clutch drive of the present utility model can also pass through the size of the control electric power outputting current and direction To adjust stress size and the direction of the copper coil 5, thus realizing multiple semi-linkage positions of the clutch.

For for one exemplary embodiment of the present utility model, it should be understood that be the guarantor of claims of the present utility model A certain demonstrative example therein in the range of shield, with the directiveness that those skilled in the art are realized with corresponding technical scheme Effect, rather than to restriction of the present utility model.
