Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail. As shown in Figure 1, of the present invention double mode trueEmpty adjustable half hydraulic mount initiatively, comprise top end opening housing, arrange and be plugged in housing top end openingThe rubber spring 2 at place, be arranged on boss 3 on rubber spring, be fixedly connected with boss on be connected spiral shellBolt 4 and the rubber counterdie 5 that is arranged at housing inside bottom, described housing comprises the upper shell being bolted1a and lower house 1b, all consolidate by fluid technology between rubber spring and upper shell and rubber spring and bossFixed, described boss, upper shell and lower house are made by aluminium alloy, are provided with lower company on described lower houseConnecting bolt 17, arranging of upper and lower connecting bolt improved the convenience of installing, and described housing inner side is near topThe position of portion is provided with rubber teleblem 6, between described rubber spring and rubber teleblem, forms air chamber 7, described inBetween rubber teleblem and rubber counterdie, form airtight and be full of the chamber of ethylene glycol liquid, in described chamber, arrangingHave the dividing plate that chamber is divided into upper chamber body 8a and lower chamber body 8b, shown in dividing plate comprise upper plate body 9a and lower body9b, the medial surface of described upper shell and lower house is respectively provided with a step surface, and described upper plate body is by rubber teleblemTwo ends be pressed on the step surface of upper shell, the two ends of rubber counterdie are pressed on lower house by described lower bodyStep surface on, on described lower house, be provided with steam vent 16, steam vent is communicated with hull outside and by rubber-soleThe region that film and lower housing cavity surround, so that equilibrium air pressure, makes the rubber counterdie can Free Transform, described inIn dividing plate, be provided with the inertia channel 10 that is communicated with Ti Yuxia chamber, upper chamber body, also comprise and be arranged on outside housing and pass throughThe vacuum valve 12 that gas channel 11 is communicated with air chamber, concrete, described gas channel vertically runs throughBoss and rubber spring, be convenient to install like this, and described vacuum valve is communicated with the inlet manifold of engine, logicalCross engine electric-controlled unit and control, make vacuum valve produce negative pressure by inlet manifold, regulate and control by vacuum valveVacuum in air chamber, is conducive to reduce energy consumption. The suspending apparatus of this structure, has simple in structure, tightGather, reliability is high, good stability, advantage that energy consumption is low, in use procedure, engine luggine by upper,Lower connecting bolt is passed to and suspends, and meanwhile, regulates the vacuum in air chamber by vacuum valve, and then changesThe contact condition of rubber spring and upper chamber body, the final change that realizes the dynamic characteristic that suspends, has reached and has adjusted outputThe object of damping force and rigidity, has effectively widened isolation frequency scope, has promoted vibration isolating effect. Concrete,According to oscillation intensity, the vacuum in vacuum valve regulation and control air chamber, makes air chamber contraction or expansion, Jin ErgaiBecome the gap between rubber spring and upper chamber body, thereby regulate the excitation of rubber spring to be passed to the journey of chamber bodyDegree, for instance, when automobile engine is in idling operation or automobile during in high speed cruising condition,Electronic control unit of automobile engine control vacuum valve, makes it to cut out, and the excitation of rubber spring cannot be directly delivered toUpper chamber body, now suspends and has the little damping characteristic of little rigidity, can effectively suppress engine idle shake or decayThe empty ring of high frequency cavity noise, the comfortableness of raising automobile; When automobile is in start operating performance, anxious accelerating mode orWhile impacting operating mode by uneven road surface etc., electronic control unit of automobile engine control vacuum valve, makes it to open rubberThe excitation of the main spring of glue can directly be passed to chamber body, now suspends and has the large damping characteristic of large rigidity, can be reliableDamped vibration, suppresses excessive displacement, prevents that engine breakthrough is spacing, thereby ensures the effective of support.
Aforementioned barriers middle part has groove, places the decoupling zero dish 14 with throttle orifice 13 in groove, upper plate body andOn lower body, all offer the inertia channel being staggeredly located with throttle orifice. In the time of low-frequency vibration, engine amplitudeGreatly, decoupling zero dish rests in groove, has closed throttle orifice and the inertia channel of decoupling zero dish, is conducive to suspend defeatedGo out larger damping; In the time of dither, engine amplitude is little, and decoupling zero dish is at groove internal vibration, inertia channelOpen with throttle orifice, alleviate the high frequency hardening phenomenon that suspends, effectively widened the isolation frequency scope that suspends.
On the mating surface of above-mentioned upper shell and lower house, upper shell and upper plate body and lower house and lower body, all establishBe equipped with sealing ring 15. Can improve sealing effectiveness, avoid the phenomenon of leakage.
Finally explanation, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although ginsengAccording to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art should be appreciated that passableTechnical scheme of the present invention is modified or is equal to replacement, and do not depart from technical solution of the present invention aim andScope, it all should be encompassed in the middle of claim scope of the present invention.
