Embodiment
In order more clearly to explain the present invention, the present invention is done to describe further below in conjunction with accompanying drawing.
See also Fig. 1, the embedded engaging and disengaging gear of axle provided by the invention core fluting electromagnetism comprises reducing motor 10, sliding axle core 11, first pin 12, copper sheathing 13, coil brace 14, coil 15, coupling shaft 16 and lateral pin 17; Form the through hole that ccontaining sliding axle core 11 passes in the coil brace 14, coil 15 is on coil brace 14; One end of sliding axle core 11 has sliding-groove, and first pin 12 is fixed on the running shaft of reducing motor 10 and places sliding-groove; The other end of sliding axle core 11 is fixedly connected with an end of copper sheathing 13, and the other end of copper sheathing 13 is provided with a breach, and this breach and lateral pin 17 are suitable, and lateral pin 17 is fixedly connected with coupling shaft 16.
Situation compared to existing technology; The embedded engaging and disengaging gear of axle core fluting electromagnetism provided by the invention; Through on the sliding axle core, offering sliding-groove, on the running shaft of motor and place sliding-groove, make the sliding axle core in the through hole of coil brace, to move back and forth first dowel fixes; When the charged generation field drives of coil sliding axle core motion, is connected with the lateral pin engaging with breach on the copper sheathing that the sliding axle core is fixedly connected, the running shaft driving coupling shaft of reducing motor rotates; When the disappearance of coil blackout magnetic field, the sliding axle core is thrown off under the effect of gravity automatically.
In the present embodiment, above-mentioned engaging and disengaging gear also comprises pressure spring 18, and pressure spring 18 1 ends lean on sliding axle core 11, and its other end leans on coil brace 14.Throw off effect for strengthening, engaging and disengaging gear also is provided with pressure spring, and when disappearing in coil blackout magnetic field, the sliding axle core quickens to throw off under the effect of pressure spring.
In the present embodiment, above-mentioned engaging and disengaging gear also comprises second pin 19, and the other end of sliding axle core 11 is fixedly connected through second pin 19 with an end of copper sheathing 13.It is understandable that; The present invention is not limited to adopt the fixed connection mode of pin, also can adopt the fixed connection of other modes, so long as the mode that the sliding axle core is fixedly connected with copper sheathing; All belong to simple deformation of the present invention or conversion, fall into protection scope of the present invention.In the present embodiment, adopting the mode of execution of copper sheathing, is in order to throw off being connected of sliding axle core and lateral pin better, to avoid the end of sliding axle core under the effect in magnetic field, to be with magnetic, reducing the possibility that clutch is failed.
