Chimwe chezvikamu zvikuru zveiginition distributor ndiyo base plate, iyo ine basa rekushanda kwebreaker.Zvose pamusoro pemapureti ekuputsa, marudzi avo aripo uye maitiro ekugadzira, pamwe chete nekusarudza, kutsiva uye kugadziriswa kwezvikamu izvi zvinotsanangurwa zvakadzama munyaya ino.
Chii chinonzi ignition distributor plate
Iyo ignition distributor plate (breaker base plate) chikamu cheiyo ignition breaker-distributor (distributor);Indiro yesimbi inoshanda setsigiro yeboka rekusangana rebreaker kana stator distributor yecontactless ignition system.
Mune carburetor uye mamwe majekiseni peturu injini, iyo ignition system inovakwa pahwaro hwechigadzirwa chemuchina - breaker-distributor, iyo inowanzonzi inongo govera.Ichi chikwata chinobatanidza midziyo miviri: chimedu chinoumba mutsara wemazuva mapfupi maperesi, uye muparadzi anovimbisa kupihwa panguva yakakodzera kwemapurusi aya kumasilinda ejini (inoita switching function).Masisitimu akasiyana ane basa rekuumbwa kweakakwira-voltage pulses mune vanogovera:
● Muhutano hwekuvhenekera - muputsi wakavakirwa paboka rekubatana, nguva nenguva rakavhurwa nekamera inotenderera;
● Mumagetsi emagetsi asingabatanidzi, sensor (Hall, inductive kana optical) inogadzira zviratidzo zvekugadzirisa zvekushandura, izvo, zvakare, zvinogadzira mapurusi e-high-voltage mu coil coil.
Masevhisi ese ari maviri - ese akajairwa anotyora uye sensor - anowanikwa akananga mudzimba yeanopisa anogovera, iwo akabatana nemuchina kune anogovera rotor.Muzviitiko zvese izvi, kutsigirwa kweaya masisitimu chikamu chakakosha - ndiro yekutyora (kana ignition distributor plate).Ichi chikamu chinoita basa rakakosha mukuita kwemugovera wese, kutadza kwayo kunowanzo kukanganisa kushanda kweiyo ignition system.Indiro yakashata inofanira kugadziriswa kana kuchinjwa, asi kuitira kugadzirisa kwakakodzera, zvinodikanwa kuti unzwisise marudzi aripo emapuleti ekuputsa, magadzirirwo avo uye maitiro.
Breaker contact group
Mhando, dhizaini uye musimboti wekushanda kweiyo ignition distributor plate
Mapureti anopwanya akakamurwa kuita mapoka maviri zvichienderana nerudzi rwekupisa dhizaini:
● Yekuonana muparadzi;
● Yekugovera pasina kubata.
Zvikamu zvine misiyano yakakura kubva kune imwe neimwe mukugadzira uye kushanda.
Breaker mahwendefa ekubata ignition system
Kune marudzi maviri eanogovera breaker base mahwendefa eiyo yekubata ignition system:
● Ndiro dzisina kutakura keji;
● Ndiro dzakabatanidzwa nekeji inotakura.
Distributor dhizaini ine yakaparadzana base ndiro uye mabatiro
Iyo yakapusa dhizaini ndiyo mahwendefa emhando yekutanga.Nheyo yekugadzirwa isimbi yakadhindwa ndiro yechimiro chakaoma, pakati payo gomba rakatenderera rinoumbwa nekorona yekukodzera kubereka.Iyo ndiro ine shinda uye maburi akareruka ekumisikidza boka rekusangana uye chigadziko chine tambo yekuzora uye yekuchenesa shaft, pamwe negomba rakaita seweji panzvimbo yekumisikidza yeboka rekusangana rekugadzirisa gap pakati pevanobatika.Mahwendefa anopiwa nebheya yakasungirirwa pahuro uye tambo yakawanda ine terminal yeimwe mhando kana imwe.Mapureti emhando iyi aishandiswa zvakanyanya muvashambadziri vakaiswa paVAZ "Classic" mota uye vamwe vamwe, muzvikamu zvakadaro chikamu ichi chinonzi "movable breaker plate".
Imwe dhizaini yakaoma ine mahwendefa evanopwanya emhando yechipiri.Zvimiro, chikamu ichi chine zvinhu zviviri: ndiro inofambiswa yekutyora uye keji inotakura.Iyo ndiro inofambisa ine dhizaini yakafanana neyakatsanangurwa pamusoro apa, pasi payo pane bhegi rekutakura - zvakare chikamu chesimbi chakadhindwa, pamativi ayo makumbo anoumbwa nemakomba ekumisikidza mumusha wevagovera.Kutakura kunowanikwa pakati peplate inofambiswa nekeji, boka rekusangana rine waya uye tambo inonzwika inoiswa pandiro inofambiswa, uye waya yakawanda yakabatana nekeji.
Mhando mbiri dzemaplateti dzakaiswa pazasi peignition distributor housing.Iyo ndiro isina cage inotakura inoiswa zvakananga muimba, iyo inoshanda secheji.Rudzi rwechipiri rweplate inogadziriswa mudzimba ine screws yakaputirwa mukati mekutakura cage.Mahwendefa anofambiswa akabatanidzwa kune vacuum corrector nenzira yekudhonza, nekudaro achichinja nguva yekubatidza zvichienderana neinjini yekushandisa mode.
Bata mhando igition distributor plate
Iyo dhizaini mahwendefa mune yekubata ignition system inoshanda seinotevera.Iyo ndiro inovimbisa nzvimbo chaiyo yeboka rekuonana maererano nemugovera shaft.Kana shaft ichitenderera, makamera ayo anorova iyo inofambiswa yekubata, ichipa kukanganiswa kwenguva pfupi kweazvino, nekuda kweiyo yakakwira-voltage pulses inogadzirwa muiyo ignition coil, iyo inopihwa kune anogovera uyezve kumakenduru mumasilinda. .Paunenge uchishandura maitiro einjini, vacuum corrector inotenderera ndiro inofambisa pane imwe kona mune imwe nzira kana imwe, iyo inowana shanduko yenguva yekupisa.Smooth kutenderera kweplate paunenge uchichengetedza kusimba kwakakwana kwechimiro chinopiwa nekutakura.
Plates of contactless ignition distributors
Kune matatu makuru marudzi easina contactless distributor plates:
● NeHoro sensor;
● Ne sensor inductive;
● Ne optical sensor.
Muzviitiko zvese, hwaro hwechikamu iplate yesimbi yakadhindwa iyo sensor kana imwe mudziyo yakaiswa.Iyo ndiro inokwidziridzwa kuburikidza nekutakura mudzimba yekugovera uye yakabatana kune vacuum corrector netsvimbo, uye maconductor anowanikwawo paplate kuti atumire masaini anogadzirwa ekudzora kune switch.
Contactless type igition distributor plate
Zvichienderana nerudzi rwemugovera, zvikamu zvakasiyana zvinogona kuwanikwa pandiro:
● Horo sensor - chigadziro chine Horo chip, umo groove inogadzirwa kune rotor yakabatanidzwa kune distributor shaft;
● A-multi-turn coil i-round coil iyo ndiyo nheyo ye inductive type sensor, magnetti yakabatanidzwa kune distributor rotor inoshanda se rotor mune yakadaro sensor;
● An optical sensor inyanzvi ine LED uye photodiode (kana photoresistor), iyo inoparadzaniswa ne groove ye rotor ine cutouts yakabatanidzwa kune distributor shaft.
Inonyanya kushandiswa ndeye sensors-distributors yakavakwa pahwaro hweHoro sensor - inogona kuwanikwa pamotokari dzeVAZ nemarori akawanda.Inductive sensors inoshandiswa zvishoma kazhinji, vaparadzi vakadaro vanogona kuwanikwa pamotokari yeGAZ-24 uye mamwe gare gare Volga, mumwe nomumwe UAZ mienzaniso uye vamwe.Optical sensors-vanogovera pamotokari dzepamba haatombo shandiswa, anogona kuonekwa pane dzimwe mota dzakagadzirwa kunze kwenyika dzine carburetor engines.
Maitiro ekusarudza uye kutsiva iyo ignition distributor plate
Munguva yekushanda kwemugovera, ndiro inopwanya inoiswa pasi pema mechanical uye thermal mitoro, izvo zvinotungamirira kune zvishoma nezvishoma kupfeka kwezvikamu zvayo (kunyanya boka rekubatana), deformations uye kukuvara.Zvese izvi zvinoratidzwa nekuipa kweiyo ignition system, kusanganisira kungoerekana yachinja nguva yekubatidza kana kusakwanisa kuigadzirisa, kutaridzika kwekukanganisa mukushanda kwemasilinda ega, kuderera kwekutanga, nezvimwe.
Kuti utsive, iwe unofanirwa kutora ndiro yekutyora chete yemhando (nhamba yekatalogi) iyo yakaiswa muparadziri kare, kana yakakurudzirwa nemugadziri wekugovera.Kuti uise ndiro itsva, zvakakosha kubvisa uye kuparadzanisa muparadzi (sezvo chikamu ichi chiri pasi pechikamu, unofanira kubvisa muparadzi uye mutongi kuti awane) - izvi zvinofanira kuitwa maererano nemirayiridzo. pakugadzirisa imwe injini kana motokari.Iyo ndiro itsva inofanira kuwira panzvimbo pasina kuedza uye kutenderera zvakasununguka mukutakura.Panguva yekuisa, kutarisisa kunofanirwa kubhadharwa kune kubatanidzwa kweplate ine vacuum corrector uye nezvose zviteshi zvemagetsi.
Kugadziriswa kweboka rekuonana nevashambadziri
Munguva yekushanda kwemuparidzi, matambudziko anogona kuoneka asingaenderane nemamiriro eplate, asi anokonzerwa nekuchinja kwepakati pakati pevanobatana neanotyora.Kuti ugadzirise dambudziko iri, iwe unofanirwa kuparadzanisa muparadzi zvishoma nekubvisa chivharo, uye kuyera mukaha pakati pevanobatika - inofanira kurara mukati memiganhu yakatarwa nemugadziri wemugovera uyu.Kana iyo gap ichisiyana kubva kune yakaiswa, zvino zvakakosha kusunungura screw inosungira boka rekubatana kune ndiro uye kugadzirisa gap, uye ipapo simbisa screw.Zvinogona zvakare kuve zvakafanira kuchenesa mabatiro kubva kune soot nejecha.
Nekusarudzwa kwakaringana uye kutsiva kweiyo breaker-distributor plate kana distributor sensor, iyo ignition system ichashanda yakavimbika uye yakavimbika mune ese injini inoshanda modes.
