Iyini ikhithi yokulungisa isikhathi semoto
Ikhithi yokulungisa isikhathi sezimoto, eyaziwa nangokuthi ikhithi yesikhathi, iyiphakheji eliphelele lokunakekela uhlelo lwesikhathi lwenjini yezimoto. Iqukethe izingxenye eziningana ezibalulekile zokuqinisekisa ukusebenza kahle nokusebenza kahle kwenjini.
Izingxenye eziyinhloko zephakheji yokulungisa isikhathi zifaka:
Ibhande lesikhathi (noma ibhande lesikhathi) : lixhuma i-crankshaft ku-camshaft ukuze kuqinisekiswe ukuthi amavalvu enjini namapiston avuleka futhi avale ngesikhathi esifanele.
i-tensioner ne-tensioner : gcina ukuqina kwebhande lesikhathi, livimbele ukuthi lingantengi noma liqine kakhulu.
idler : nciphisa ukuguga kwebhande lesikhathi, andise impilo yalo yesevisi.
amabhawodi, amantongomane, ama-gaskets nezinye izinsimbi: ezisetshenziselwa ukulungisa nokulungisa uhlelo lwesikhathi engxenyeni ngayinye.
Ngaphezu kwalokho, ezinye izinhlobo zesethi yesikhathi zingase futhi zihlanganise nepompo yamanzi, ukuze ekulungiseni nasekushintsheni kube lula futhi kukhathazeke, ukugwema isidingo esilandelayo sokuqaqa nokuhlanganisa injini futhi.
Kudingeka kakhulu ukushintsha isikhathi esimisiwe njalo, ngoba ibhande lesikhathi liyinto egugile, futhi uma liphukile, lingabangela umonakalo omkhulu enjinini. Ngakho-ke, abanikazi bayelulekwa ukuthi bashintshe isikhathi esisethwe njalo ngokuhambisana nebhukwana lokulungisa lomkhiqizi wemoto ukuze kuqinisekiswe ukusebenza okuvamile nokuphepha kwemoto.
Umsebenzi oyinhloko wephakheji yokulungisa isikhathi sezimoto ukuqinisekisa ukusebenza okuvamile kwesistimu yesikhathi senjini, okuhlanganisa ukugcinwa nokufakwa esikhundleni kwebhande lesikhathi, i-tensioner, i-idler nezinye izinto ezibalulekile. Ikhithi yokulungisa isikhathi iyiphakheji eliphelele lokulungiswa kwenjini yezimoto, okuhlanganisa i-tensioner, i-tensioner, i-idler kanye nebhande lesikhathi elidingwa uhlelo lokudlulisa isikhathi, kanye namabhawudi, amantongomane, ama-gaskets nezinye ihadiwe.
Lezi zingxenye ziyitshe legumbi lokusebenza okuvamile kwenjini, futhi ukushintshwa njalo kwalezi zingxenye kungaqinisekisa ukuthi injini isebenza esimweni esifanele futhi kugweme ukulahlekelwa amandla nokwehluleka ngenxa yokuguga noma ukulimala kwezingxenye.
Ukukhetha iphakethe eliphezulu lokulungisa isikhathi akukwazi nje ukuthuthukisa ukusebenza kahle kwenjini, kodwa futhi kwandise ukuphila kwayo kwenkonzo. Izingxenye zangempela zingafanisa ngokunembile uhlelo lwesikhathi lwemoto, zithuthukise ukusebenza kahle komlilo namandla okukhipha amandla, ukuze kuqinisekiswe ukusebenza okuzinzile kwemoto nokushayela okuvamile.
Ukwengeza, ukuhlola okuvamile nokushintshwa kwezingxenye kuphakheji yokulungisa isikhathi kuyisinyathelo esibalulekile sokuvimbela ukwehluleka, ngoba isimo sezingxenye ezindala sizothinta ngokuqondile impilo yesevisi nokusebenza kwezingxenye ezintsha.
Ikhithi yokulungisa isikhathi (eyaziwa nangokuthi ikhithi yesikhathi) iyiphakheji ephelele yokunakekelwa kwesistimu yesikhathi yenjini yezimoto, ngokuvamile ehlanganisa izingxenye ezibalulekile ezilandelayo:
Ibhande lesikhathi
Ibhande lesikhathi liyingxenye eyinhloko yephakheji yokulungisa isikhathi, elibophezelekile ukuxhuma i-crankshaft ne-camshaft, ukuqinisekisa ukuthi i-valve yenjini ne-piston ivula futhi ivale ngesikhathi esifanele. Uma ibhande lesikhathi lilimele, lingase libangele ukwehluleka okukhulu kwenjini.
tension wheel kanye ne-tensioner
Isondo le-tensioner kanye ne-tensioner kusetshenziselwa ukugcina ukuqina okufanele kwebhande lesikhathi futhi kulivimbele ukuthi lixege noma liqine ngokweqile, ngaleyo ndlela kuqinisekiswe ukusebenza okuzinzile kwesistimu yesikhathi.
idler
Indima yomuntu ongenzi lutho ukunciphisa ukuguga kwebhande lesikhathi, ukwelula impilo yalo yesevisi, nokusiza ukulungisa umzila wokugijima webhande.
amabhawudi, amantongomane namagaskets
Lezi zingxenye zehadiwe zisetshenziselwa ukulungisa nokulungisa izingxenye ezihlukahlukene zesistimu yesikhathi ukuze kuqinisekiswe ukuthi i-timing drivetrain nenjini kusesimweni esifanele ngemva kokulungiswa.
Ezinye izingxenye ozikhethela
Ezinye izinhlobo zamaphakeji okulungisa isikhathi zingase futhi zifake amaphampu amanzi, ukuze kube lula ukushintsha ukugcinwa nokugwema isidingo esilandelayo sokuqaqa injini futhi.
isifinyezo : Ikhithi yokulungisa isikhathi iyingxenye ebalulekile yokunakekelwa kwemoto, ukushintshwa okujwayelekile kungagwema ukwehluleka kwenjini kanye nokwenyuka kwezindleko zokuyilungisa. Kunconywa ukuthi abanikazi bezimoto bahlole futhi bashintshe ikhithi yokulungisa isikhathi njalo ngokuhambisana nebhukwana lokulungisa lomkhiqizi wemoto ukuze kuqinisekiswe ukusebenza okuvamile nokuphepha kwemoto.
