Iyini i-timing yemoto ye-tensioner
I-automotive time tensioner iyithuluzi elibalulekile ohlelweni lokudlulisela lwebhande lesikhathi lenjini yezimoto noma iketango lesikhathi. Umsebenzi wayo oyinhloko ukuqondisa nokuqinisa ibhande lesikhathi noma iketango ukuze kuqinisekiswe ukuthi ligcinwa lisesimweni esihle kakhulu sokushuba. Enqubweni yokudlulisa, ibhande lesikhathi noma iketango linomthwalo wemfanelo wokushayela i-camshaft ukuze uvule futhi uvale i-valve ngesikhathi, futhi uqedele izinqubo ezine zokuthatha, ukucindezela, ukusebenza kanye nokukhipha i-piston. Kodwa-ke, lezi zingxenye zizoshaya umoya lapho zisebenza ngesivinini esiphakathi nendawo nephezulu, futhi zizonwetshwa futhi zikhubazeke ngenxa yezinkinga zezinto ezibonakalayo kanye namandla ngesikhathi sokusetshenziswa isikhathi eside, okuholela ekubambeni kwesikhathi kwe-valve okungalungile, okuholela ezindlekweni zikaphethiloli wemoto, amandla anganele, ukungqongqoza nezinye izinkinga. Ezimeni ezibucayi, amazinyo amaningi okweqa angabangela ukuthi ivalvu ishayisane nepiston engenhla, kulimaze injini.
Isimiso sokusebenza
I-timing tensioner yenza umsebenzi wayo ngesistimu ye-tensioner ekhethekile ehlanganisa i-tensioner, isondo elicindezelayo noma isitimela esiqondisayo. I-tensioner inikeza ingcindezi ebhandeni noma kuketango, i-tensioner ithintana ngqo nebhande lesikhathi, futhi umhlahlandlela uthintana ngqo neketango lesikhathi. Enqubweni yokugijima ngebhande noma iketango, bafaka ingcindezi ye-tensioner ebhandeni noma iketango ukuze kugcinwe isimo esifanelekile sokudonsa.
uhlobo
Kunezinhlobo eziningi ze-tensioner yesikhathi, ikakhulukazi okuhlanganisa ukwakheka okungaguquki kanye nesakhiwo sokulungisa esizenzakalelayo esinwebekayo. Isakhiwo esingaguquki sivame ukusebenzisa i-sprocket eguquguqukayo ukulungisa ibhande noma i-chain tension degree; Isakhiwo sokulungiswa okuzenzakalelayo esinwebekayo sincike ezingxenyeni ezinwebekayo ukuze zilawule ngokuzenzakalelayo ukushuba kwebhande noma iketango, futhi singazibopha kabusha ngokuzenzakalelayo. Ngaphezu kwalokho, i-timing tensioner esetshenziswa ezimotweni zesimanje ngokuvamile ihlukaniswa ngezindlela ezimbili: i-hydraulic ne-mechanical, engalungisa ngokuzenzakalelayo ukushuba kwebhande lesikhathi kanye neketango lesikhathi ukuze kuqinisekiswe ukusebenza okuvamile kwenjini.
Umsebenzi oyinhloko we-tensioner yezimoto ukuqinisekisa ukuthi ibhande lesikhathi noma uchungechunge lwezikhathi lwenjini luhlala lusesimweni esingcono kakhulu sokuqinisa. Ngokukhethekile, i-tensioner iqinisekisa ukuzinza nokuthembeka kwesistimu yesikhathi senjini ngokulungisa ngokuzenzekelayo ukushuba kwebhande lesikhathi noma iketango ukuze livinjwe ukuthi lingaxegi noma liqine kakhulu.
Isimiso sokusebenza kanye nohlobo
I-tensioner ingasebenza ngazo zombili izindlela zokudonsa amanzi kanye nemishini. I-tensioner yokucindezela uwoyela incike ekucindezelweni kukawoyela wenjini ukulungisa ukushuba, kuyilapho i-tensioner eyimishini ilungisa ukungezwani ngesakhiwo somshini njengesiphethu. Noma iyiphi indlela, i-tensioner ingalungisa ngokuzenzakalelayo ukushuba ukuze kuqinisekiswe ukusebenza okuvamile kwesistimu yesikhathi.
Ukwakheka kwesakhiwo
I-tensioner ngokuvamile iqukethe i-tensioner kanye nesondo elicindezelayo noma umzila wesitimela. I-tensioner ihlinzeka ngomfutho, isondo le-tensioner lixhumene ngqo nebhande lesikhathi, kanti isitimela esiqondisayo sixhumene ne-timing chain ukuze zihlale ziqine kahle ngesikhathi sokusebenza. Lo mklamo uqinisekisa ukuthi ibhande lesikhathi kanye neketanga lesikhathi kuhlala kusesimweni esihle kakhulu sokuqiniswa ngesikhathi sokudlulisa.
