Ayini ama-Starter Motors?

I-Starter Motors isihlinzeka ngendlela esebenzayo yokuqalisa kabusha izimoto zethu lapho ibhethri lifa noma sijika injini ngephutha ngenkathi isebenza, noma sidinga ukuyijika singalindele ngenkathi isebenza. Benza ukuqalisa kwenjini kuphephe futhi kube lula kunokuklolodela ngesandla.

Ngokushesha nje lapho ukhiye uphendulwa, amandla aphuma ebhethrini ageleza ngamakhoyili enkambu axhunywe endaweni yokuqalisa futhi angene endaweni kazibuthe kagesi ephendula igiya elincane elaziwa ngokuthi iphinikhodi kusiqalisi.

I-Overrunning Clutch

Ama-Starter motor overrunning clutches asetshenziselwa ukuvimbela amagiya eringi enjini ukuthi ashayele i-starter motor Armature ngqo, futhi angase abangele ukweqa kwe-Armature yayo nge-Armature yayo. 

Ukugijima ngokweqile kungabangela ukuba isiqalisi sijike ngokushesha kune-flywheel yenjini, futhi ekugcineni kubangele ukuba ingaphumeleli ngokuphelele - lokhu kuvame ukuba ngesinye sezimbangela eziyinhloko zokwehluleka kwesiqalisi.

 Ukuhlola okulula ukubona ukuthi lokhu kungenzeka yini kuwukukhipha isiqalisi sakho bese usiphendulela ngakolunye uhlangothi ukusuka ku-motor shaft rotation, uma kwenzeka iphini laso lingazungezi lokho kukhombisa inkinga ye-clutch eyeqile noma i-clutch ehlulekayo ukweqa.

Ama-clutch overrunning ohlobo lwe-Sprag aklanyelwe ukusebenzelana ngokumangazayo ngesivimbo sokuhamba se-axial esakhiwe emaphethelweni angaphandle egiya langaphakathi futhi sibe nendawo evulekile lapho kuya khona lapho kanye ne-bore yayo yangaphakathi engaphansi kwe-backlash. 

Kwezinye iziphetho kukhona ihlombe le-peripheral elingaphakathi elakhiwe phezu kwekesi lesikhungo se-starter njengengxenye yomklamo walo; zombili izingxenye zifaka i-resin njengento eyisisekelo ngokuphelele ngaphakathi komklamo wazo.

I-Solenoid

I-starter solenoid iyisisetshenziswa esincane esifakwe phezulu kwe-starter motor exhuma intambo yayo yokulawula ne-flywheel noma i-flex plate ngokusebenzisa othintana nabo abasindayo, iphendulela injini yakho uma uyikhanyisa noma inkinobho yokuqalisa icishiwe. 

I-solenoid ebuthakathaka ingase yenze umsindo wokuchofoza ozwakalayo, noma mhlawumbe kungabikho nhlobo umsindo lapho inkinobho yokuqalisa icishiwe. Uma ingasebenzi kahle kungaholela emisindweni yokuchofoza ebuthakathaka uma ucindezela noma ungabibikho ngisho nomsindo uma uqala injini.

I-solenoid yenziwa isebenze uzibuthe kagesi okhiqiza inkambu kazibuthe eheha futhi ibambelele kumongo we-armature, ohlanganisa idiski elincane elinesigxobo esisodwa sensimbi ngakolunye uhlangothi kanye nomzimba wekhoyili kolunye. Ungavakashela leli sayithi ukuze ufunde kabanzi.

I-spring exhunywe kulo mongo ibangela ukuthi ijikeleze kokubili ngokuzungeza kanye ne-axially - lokhu kunyakaza kudluliselwa ngegiya ku-starter drive shaft ezungeza i-crankshaft ngenkathi ijika i-flywheel noma amagiya e-flexplate kanyekanye.

Njengoba umjikelezo wokuqala uqala futhi i-solenoid icushwa ukuze igxilise amandla kazibuthe ukusuka ku-armature core armature kuya kumakhoyili, i-air gap voltage times flux ikhiqiza amandla okuqala abalulekile ashayela ama-flywheel noma ama-flexplate rings bese iqalisa injini.

Njengoba igiya le-pinion liphenduka, libangela ukuthi i-flywheel isheshise. I-sprag clutch yendlela eyodwa eza ijwayelekile kuziqalisi eziningi isebenzisana negiya eliyindandatho ku-flexplate noma i-flywheel ukuze imise i-backdrive ukuthi ingenzeki futhi iyivikele ekushayeni igiya le-pinion futhi ilimaze ngokuqhubekayo.

Uma isiqalisi singakhiqizi ukuchofoza okukhulu lapho sivuliwe noma izinkinobho ziphushwa, lokhu kungase kubonise noma ukugoqa okubuthakathaka kwe-solenoid yaso, ukumelana nesixhumi saso sokuthinta nokungavaleki kahle, noma kuphela okuncane okugeleza kusuka kumatheminali esindayo esindayo sesiqalisi kuya kumotho wayo uqobo. 

I-Pinion Gear

Izinjini zokuqalisa zinegiya elincane ekugcineni kweshafti yazo yenjini elaziwa ngokuthi igiya lephinikhodi elisebenzisa igiya elikhudlwana ku-flywheel ukuze likhiqize amandla aphendukayo futhi likhiqize itorque ephezulu ngesivinini esiphansi, okudala isilinganiso esisebenzayo setorque/ijubane eliphansi elidingekayo ukuze kuqalwe injini. Lokhu kuhlelwa kwegiya kusiza ekunikezeni umfutho owanele wokuqala odingekayo ukuze izinjini zokuqalisa ukukhahlela ngempumelelo.

Uma uma uphendula ukhiye uzwa kuphela umsindo ohelezayo noma ogayayo, kukhona okushaya amanzi ngomshini ophusha igiya eliphina ukuze libambe isondo lokuhamba. Enye indlela lokhu kungase kuhluleke ngayo: kungahle kwehluleke ngokuphelele ukuzibandakanya, noma kuhileleke kodwa bese kushelela kudlule i-clutch yayo okubangela ukushelela kwe-clutch.

Amamotho aqalayo asebenzisa isistimu yezikhonkwane ezibandakanya inertia, lapho i-Bendix ivele yaphendula iphinikhodi ukuze iyihlanganise negiya leringi ye-flywheel. Kodwa njengoba injini yayigijima futhi isheshisa, ukungaguquguquki kwayo kwabangela ukushesha kakhulu phakathi kwalezi zingxenye okuholele ekutheni ziphume ekuvumelaneni futhi zilahle ukuxhumana enye kwenye futhi ithumele iphiyoni lijike libuyele emuva eduze kwama-helical splines ayo ngendlela engalindelekile. 

Lokhu kwakuyingozi kakhulu.

Kamuva, kwaqaliswa uhlelo lwephinikhodi oluphephile nolulula olubanjelwe ngaphambili. I-solenoid enamathiselwe kumamotho aqalayo e-My Auto Parts isebenza njenge-electromagnetic relay. Uma isignali engu-12 Volt isetshenziswa kutheminali ye-ignition switch 50 inika amandla i-solenoid ebese icupha injini yesiqalisi futhi ivumele i-pinion ukuthi iphume ikhava yokuvikela kuze kube yilapho injini iphendula i-flywheel.

Igiya le-pinion lifaka intambo yesifazane ngaphakathi kwayo exhuma nentambo yesilisa ku-starter shaft, kuyilapho kukhona isihlahla senjoloba noma intwasahlobo esebenza njengomcamelo ogcwele kakhulu futhi ivumela ukushelela ngaphansi kwezimo ezimbi kakhulu.

Oxhumana naye

Lapho nje uvula ukhiye wakho noma ucindezela inkinobho yesiqalisi, ugesi ugeleza uye kusistimu yokuthungela, uqhumise amapulaki ezinhlansi, bese wenza kusebenze iswishi enkulu kazibuthe eyaziwa ngokuthi i-solenoid. 

Le swishi iqondisa amandla aphezulu e-amperage ukusuka kubhethri lakho ngqo kumotho, amagiya ane-meshing. Ukwengeza, inyakazisa i-lever yemfoloko exhunywe egiyeni le-pinion ukuze ixhumane ne-flywheel noma i-flexplate kuye ngohlobo lwenjini - bese ihambisa i-lever yemfoloko eyiphusha ukuze ihambisane ne-flywheel noma i-flexplate (kuye ngokuthi uhlobo).

Izinjini zikagesi zisebenzisa amandla abalulekile lapho ziqala futhi zidinga okuncane kakhulu ukuze zigcine isivinini sazo ngemuva kwalokho. Ukuphakama kwamandla okuqala, okwaziwa ngokuthi i-inrush current, kungase kufinyelele izikhathi eziningana kunokokusebenza okuvamile kwenjini futhi kungase kuncibilikise amatheminali okuxhumana kwealloy kuziqalisi zenjini uma insimbi eveziwe ikhona. Ukuze izivikele ezimweni ezinjalo, iziqalisi zezimoto zifika zifakwe ama-relay agcwele ngokweqile aqapha ukugeleza kwamanje futhi avale amandla kusekethe uma iqala ukukhuphuka kakhulu.
