Compare with traditional electromagnet silencing means that is used for brake, the utility model is used for the embedded-type electric magnet silencing means of brake, has easily advantage of high, installation of life-span and maintenance operation.Static iron core and end cap are closed the structure of making cavity, greatly save raw material and machining period, and reduced manufacturing process flow.Damping device is positioned at core interior, but not coil inside, it is reduced by the impact of electromagnetic heating greatly, and the life-span also can significantly improve.
Description of drawings
The structural representation of a kind of embedded-type electric magnet silencing means for brake that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, a kind of embedded-type electric magnet silencing means for brake that the utility model provides comprises housing 1, is provided with the inner core 2 that is driven by moving iron core 5 in housing 1.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 in static iron core 6 and the side that moving iron core 5 deviates from mutually.End cap 3 is connected and fixed by bolt and housing 1 and static iron core 6.Be formed with cavity between the inwall of a end that static iron core 6 and moving iron core 5 deviate from mutually and end cap 3, the shape of cavity is any, and in the utility model, cavity is cylindrical or square.Vibration when clashing into static iron 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 described 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 is connected with moving iron core 5 interference after passing successively end cap 3, damping device 7, baffle plate 8 and static iron core 6.Baffle plate 8 is stuck on the axle 9, and in the present embodiment, baffle plate 8 is by a kind of being stuck on the described 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, so that moving iron core 5 rapid shock arrive static iron core 6, this damping device 7 is set on the axle 9.
