Umqalisi wemoto yombane ulawulwa sisixhobo esikhethekileyo esikumzimba wayo - i-retractor (okanye i-traction) relay.Funda konke malunga nokuhanjiswa kwe-retractor, uyilo lwazo, iindidi kunye nomgaqo wokusebenza, kunye nokukhetha okuchanekileyo kunye nokutshintshwa kweereyilayi xa kwenzeka ukuphuka.
Yintoni i-starter retractor relay?
I-Starter retractor relay (i-traction relay) - indibano yesiqalisi sombane wemoto;I-solenoid edibeneyo kunye neqela loqhagamshelwano, elinika uxhulumaniso lwe-motor starter kwibhetri kunye nokudibanisa komatshini we-starter kwisithsaba se-flywheel xa uqala injini.
I-retractor relay ingena kumatshini kunye neendawo zombane ze-starter, zilawula ukusebenza kwazo ngokubambisana.Le nodi inemisebenzi emininzi:
- Unikezelo lwe-starter drive (i-bendix) kwindandatho yegiya ye-flywheel xa uqala injini kwaye uyibambe de kukhutshwe isitshixo sokutshisa;
- Ukuqhagamshela injini yokuqalisa ibhetri;
- Rhoxisa i-drive kwaye ucime isiqalisi xa iqhosha lokutshisa likhutshwa.
Nangona i-relay yokutsala isebenza njengenxalenye ye-starter, yiyunithi eyahlukileyo edlala indima ebalulekileyo ekusebenzeni kwenkqubo yokuqalisa injini.Nakuphi na ukungasebenzi kakuhle kwale yunithi kwenza kube nzima kakhulu ukuqalisa injini okanye kwenza ukuba kungenzeki, ngoko ukulungiswa okanye ukutshintshwa kufuneka kwenziwe ngokukhawuleza.Kodwa ngaphambi kokuthenga i-relay entsha, kufuneka uqonde iintlobo zayo, iimpawu kunye nomgaqo wokusebenza
Uyilo, iintlobo kunye neempawu zeereyitha zokubuyisela
Okwangoku, abaqalisi bombane basebenzisa i-retractor relays yoyilo olufanayo kunye nomgaqo wokusebenza.Le yunithi iqulethe izixhobo ezibini ezidityanisiweyo - i-relay yamandla kunye ne-solenoid ene-armature ehambayo eyivulayo (kwaye kwangaxeshanye izisa i-bendix kwi-flywheel).
Isiseko soyilo yi-solenoid ye-cylindrical ene-windings ezimbini - i-retractor enkulu kunye nokugcina isilonda esinye phezu kwayo.Ngasemva kwe-solenoid kukho indlu ehambisa i-relay eyenziwe nge-dielectric material ehlala ixesha elide.Iibholiti zoqhagamshelwano zibekwe eludongeni lokugqibela lwe-relay - ezi zii-terminals zecandelo eliphezulu apho umqali uqhagamshelwe kwibhetri.Iibholiti zinokuba yintsimbi, ubhedu okanye ubhedu, ukusetyenziswa koqhagamshelwano olunjalo kubangelwa yimisinga ephezulu kwisekethe yokuqala xa uqala injini - ifikelela kwi-400-800 A okanye ngaphezulu, kwaye iitheminali ezilula ezinomsinga onjalo ziya kunyibilika nje.
Umzobo we-Wiring we-retractor relay kunye noqhagamshelwano olongezelelweyo kunye ne-relay eyongezelelweyo yokuqalisa
Xa iibholiti zoqhagamshelwano zivaliwe, i-retractor winding ifutshane (ii-terminals zayo zisondele komnye nomnye), ngoko iyayeka ukusebenza.Nangona kunjalo, i-winding egcinayo isaqhagamshelwe kwipakethi yebhetri, kwaye indawo yemagnethi iyenzayo yanele ukubamba i-armature ngokukhuselekileyo ngaphakathi kwe-solenoid.
Emva kokuqaliswa ngempumelelo kwe-injini, isitshixo sokutshisa sibuyela kwindawo yaso yokuqala, ngenxa yoko ukugcinwa kwesekethe yokucima ikhefu - kule ntsimi yamagnetic ejikeleze i-solenoid iyanyamalala kwaye i-armature ikhutshwe ngaphandle kwe-solenoid phantsi kwesenzo se-solenoid. entwasahlobo, kwaye intonga iyasuswa kwiibholithi zoqhagamshelwano.I-starter drive isusiwe kwisithsaba se-flywheel kwaye isiqalo sicinyiwe.I-relay yokutsala kunye nesiqalisi sonke zitshintshelwa kwindawo yokulungela ukuqala okutsha kwe-injini.
Imiba yokhetho, ukulungiswa kunye nokutshintshwa kwereyilayi yeretractor
I-relay ye-traction ixhomekeke kwimithwalo ebalulekileyo yombane kunye noomatshini, ngoko ke kukho amathuba aphezulu okungaphumeleli kwawo kunye nokusebenza ngononophelo.Ukungasebenzi kakuhle kwale yunithi kungqinwa yimiqondiso eyahlukeneyo - ukungabikho kophawu lokunkqonkqoza kwi-starter drive unikezelo xa i-ignition ivuliwe, ukujikeleza okubuthathaka kwe-starter xa ibhetri ihlawuliswa, "ukuthula" komqalisi xa uqhuba. unikezelo luyasebenza, kunye nabanye.Kwakhona, ukungasebenzi kakuhle kubonwa xa i-relay ibaleka - ngokuqhelekileyo kukho ikhefu kwii-windings, ukwanda kokumelana kwisekethe yamandla ngenxa yokutshisa kunye nokungcoliswa kwabafowunelwa, njl. njengekhefu kwi-retractor okanye ukugcina i-windings, ukuphulwa kwebholithi yoqhagamshelwano, kunye nabanye), ngoko kulula kwaye kungabizi ukubuyisela ngokupheleleyo i-relay.
Isixhobo esiqhelekileyo somqalisi wombane kunye nendawo ye-retractor relay kuyo
Kuphela ezo ntlobo kunye neemodeli ze-retractor relays ezichazwe ngumenzi wesithuthi kufuneka zikhethelwe ukutshintshwa.Ukuthengwa kufuneka kwenziwe ngamanani ekhathalogu - le yindlela yodwa yokutshintsha ngokuzithemba i-node kwaye wenze umqalisi asebenze ngokuqhelekileyo.Kunzima okanye akunakwenzeka ukufaka i-relay yolunye uhlobo (ngenxa yemilinganiselo engalinganiyo), kwaye ukuba oku kunokwenziwa, umqalisi akanakusebenza ngokuchanekileyo okanye angenzi umsebenzi wawo oyintloko.
Ukutshintsha i-relay, i-starter yombane kufuneka ikhutshwe kwi-injini kwaye ihlanjululwe, ngokufuthi isebenzisa isixhobo esikhethekileyo.Xa ufaka i-relay entsha, uxhulumaniso lombane kufuneka lwenziwe ngokucophelela - iingcingo zihluthwe ngaphambili kwaye zixutywe, xa zilungiswa kwii-terminals, ukuthembeka kufuneka kuqinisekiswe ngokuthintela ukutshisa kunye nokufudumala.Yonke imisebenzi yenziwa ngokufanelekileyo ngokuhambelana neziphakamiso ezichazwe ngumenzi we-automaker kwimiyalelo yokulungiswa nokugcinwa kwesithuthi.
Kwixesha elizayo, i-relay traction, njenge-starter ngokwayo, idinga kuphela ukuhlolwa kwexesha kunye nokuqinisekiswa ngokuhambelana nemimiselo yokugcina.Ngokukhetha okufanelekileyo kunye nokutshintshwa, le yunithi iya kusebenza ngokuthembekileyo nangokufanelekileyo, iqinisekisa ukuqala ngokuzithemba kwenjini.
