Preferably, thus link to each other through bolt between said static iron core and the said end cap and form said cavity.
Preferably, said cavity is cylindrical or square.
Preferably, the inwall of said end cap is close in a side end face of said damping device, and its opposite side end face is close to baffle plate, and baffle wedge is on said axle.
Preferably, said baffle plate is through a kind of being stuck on the said axle in step-like structure, circlip for shaft structure or the over-surplus fit structure.
Preferably; Said damping device adopts a kind of in rubber-like damping material, resinae damping material, spring-like damping material, grease or the fluid oil damping material or the composite damping material of resinae damping material or grease or fluid oil damping material and spring or rubber.
Compare with traditional electromagnet silencing means that is used for brake, the present invention is used for the embedded electromagnet silencing means of brake, has life-span height, installation and maintenance operation advantage easily.Static iron core and end cap are closed the structure of making cavity, save raw material and machining period greatly, and reduced manufacturing process flow.Damping device is positioned at core interior, but not coil inside, it is reduced by the influence of electromagnetic heating greatly, and the life-span also can significantly improve.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the embedded electromagnet silencing means of brake provided by the invention.
Embodiment
For making the present invention more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, a kind of embedded electromagnet silencing means that is used for brake provided by the invention comprises housing 1, in housing 1, is provided with the inner core 2 that is driven by moving iron core 5.Housing 1 is cylindrical with inner core 2.Side at moving iron core 5 is provided with static iron core 6, is provided with end cap 3 at static iron core 6 with the side that moving iron core 5 deviates from mutually.End cap 3 is connected fixing with housing 1 and static iron core 6 through bolt.Between the inwall of end that static iron core 6 and moving iron core 5 deviate from mutually and end cap 3, be formed with cavity, the shape of cavity is any, and in the present invention, cavity is cylindrical or square.The vibration when clashing into fixed core 6 in order to absorb moving iron core 5 and the damping device 7 of noise are positioned at this cavity.Damping device 7 adopts a kind of in rubber-like damping materials, resinae damping material, spring-like damping material, grease or the fluid oil damping material or the composite damping material of resinae damping material or grease or fluid oil damping material and spring or rubber.The inwall of said end cap 3 is close in one side end face of damping device 7, and its opposite side end face is close to baffle plate 8.Circular or other arbitrary shape are adopted in baffle plate 8 outer rings.One end of axle 9 is exposed to outside the end cap 3, and the other end passes end cap 3, damping device 7, baffle plate 8 and static iron core 6 backs successively and is connected with moving iron core 5 interference.Baffle plate 8 is stuck on the axle 9, and in the present embodiment, baffle plate 8 is through a kind of being stuck on the said axle 9 in step-like structure, circlip for shaft structure or the over-surplus fit structure.Left side and right side at moving iron core 5 and static iron core 6 are respectively equipped with one group of coil 4; All coils 4 connects external power source with the form of serial or parallel connection; After coil 4 energisings; Between static iron core 6 and moving iron core 5, produce electromagnetic force, make moving iron core 5 rapid shock to static iron core 6, this damping device 7 is set on the axle 9.
When solenoid 4 energisings, to static iron core 6 one sides, meanwhile, the bump vibration and noise of moving iron core 5 is absorbed by the damping device in the cavity 7 moving iron core 5 by adhesive, makes impact noise and vibration farthest reduce.When moving iron core 5 by adhesive to 6 last times of static iron core, the electromagnetism gap between moving iron core 5 and the static iron core 6 is very little, required maintenance electromagnetic force is also less.In the whole process of moving iron core 5 actions, damping device 7 acts on the moving iron core 5 always, therefore can reach the effect that slows down moving iron core 5 responsivenesses greatly.Compare with traditional electromagnet silencing means that is used for brake, the present invention is used for the embedded electromagnet silencing means of brake, has life-span height, installation and maintenance operation advantage easily.Static iron core 6 and end cap 3 closed the structure of making cavity, saved the expense of raw material, machining period greatly, and reduced manufacturing process.Damping device 7 is positioned at the core interior that end cap 3 and static iron core 6 are formed, but not coil 4 inside, it is reduced by the influence of electromagnetic heating greatly, and the life-span also will raise greatly.
