amabhande esikhathi
Ibhande lesikhathi elihle noma ibhande ledrayivu lensizakalo linesikhathi esithathayo ukuqedela i-orbit eyodwa emhlabeni wonke empilweni yalo.
Ibhande elihle elinamazinyo noma ibhande le-accessory drive lihamba ibanga elilingana nokuzungeza okukodwa emhlabeni empilweni yawo, futhi amazinyo ebhande lesikhathi ahlanganyela izikhathi eziningi njengoba kunabantu emhlabeni. Ekupheleni kwethanga, ibhande kufanele lishintshwe. Yiqiniso, uma kunesidingo, ibhande kufanele lishintshwe ngaphambili.
EYurophu kuphela, amabhande esikhathi ayizigidi ezingu-40 ashintshwa minyaka yonke. Kulesi sibalo kufanele kwengezwe amabhande e-accessory drive (anjenge-Multi-V) atholakala emotweni ngayinye. Amabhande ayingxenye yesistimu yama-pulleys, ama-tensioner, ama-seal namaphampu amanzi okuvame ukudinga ukushintshwa ngesikhathi esisodwa.
Ibhande lesikhathi liyindlela ethule futhi engadlidlizi yokuvumelanisa amavalvu nayo yonke injini. Manje ibaluleke kakhulu enjinini kunangaphambili. Cishe yonke injini entsha ishayisana lapho amavalvu namapiston kusondelene. Ibhande lesikhathi eliqhekekile noma eliphukile lingabangela i-piston ukuthi ishaye i-valve evulekile, ibangele ukuthi ama-valve agobe, amaphistoni aqhume, futhi ngenxa yalokho kube nokulimala okukhulu kwenjini.
Noma izinjini ezingashayisani zingalimali ngendlela efanayo nezinjini ezingashayisani, uma kwenzeka iphutha le-timing belt, umshayeli uzogcina eseceleni nenjini engasebenzi. Namuhla, ibhande lesikhathi liyingxenye ebalulekile yesistimu yokusabalalisa igesi, kanye nomjovo namaphampu amanzi.
Ibhande le-Multi-V kanye nebhande le-accessory drive yizinto ezijwayelekile ezimotweni ezenziwe kusukela ngasekupheleni kweminyaka yamashumi ayisishiyagalolunye. Anikeza ukwethembeka okukhulu kanye nomthamo omkhulu womthwalo kunamabhande amadala angama-V. Ngokufika kwe-power steering kanye ne-air conditioning, ama-V-belt amaningi abaluleke kakhulu ekusebenzeni kwezinsiza. Emotweni enebhande le-Multi-V elilimele, i-alternator ingalimala, ilahleke isiteringi sikagesi, futhi esimweni esibi kakhulu, ibhande lingangena ohlelweni lwesikhathi.
Ibhande noma iketango?
Selokhu kwethulwa ibhande le-timing, ukusebenza kwalo kushintshile ngenxa yokwakhiwa kwezinto ezintsha nezimo zamazinyo ezikwazi ukumelana namazinga okushisa aphezulu namandla enjini. Imodeli ngayinye yenjini ngokuvamile inemodeli yayo yebhande. Emashumini eminyaka amuva nje, iningi labakhiqizi bezimoto eYurophu bakhethe amabhande esikhathi. Kodwa amaketanga esikhathi ayabuya, futhi manje atholakala ku-20% kuya ku-50% wezinjini zakamuva ezenziwe izinkampani zezimoto.
“Mhlawumbe abakhiqizi bebenezinkinga ngokufaka amabhande phambilini kanti namaketango athatha indawo encane phambi kwenjini. Nokho ukushintsha i-timing chain ufake i-timing chain ngokuvamile kudinga ukususwa kwenjini nengaphambili lonke lenjini, okudinga isikhathi nemali ethe xaxa ngokubuka kwekhasimende,” kusho uMaurice Foote, oyi-SKF Engine Manager. Yize ibhande le-Multi-V selijwayelekile, awekho amabhande ajwayelekile. Kungase kube khona okungenani amabhande okushayela ambalwa ahlukene anobude obuhlukahlukene kumodeli yenjini ngayinye. Kuya ngemishini efakwe emotweni. Ubude bebhande bubaluleke kakhulu - ngisho namamilimitha acatshangelwa lapha. Ake sithi ibhande lokuqala le-Multi-V lemoto linobude obungamamilimitha angu-1691. Abanye abathengisi bangase banikeze ibhande elifushane njengo-1688mm, bathi ubude obufanele bemodeli yemoto yakho. Kodwa-ke, lawo mamilimitha amathathu ashodayo angabangela ukudlidliza okudlulele noma umsindo kanye nokushelela uma umdlalo ungekho phakathi kwebanga elivumelekile le-auto tensioner.
Amabhande amaningi e-V
Ibhande le-Multi-V lisebenza ezindaweni ezinzima. Ivame ukuvezwa ukungcola, amanzi namafutha, futhi imoto ehlomele kangcono, ukucindezeleka okukhulu ebhande kuyanda.
Ukusebenza okuthuthukisiwe kwe-aerodynamic kwezimoto kusho ukuhamba komoya okuncane namazinga okushisa afudumele ngaphansi kwe-hood, noma njengoba ungase usho, injini eyengeziwe endaweni encane. Izinjini ezinamandla kakhulu ezisebenza emazingeni okushisa aphezulu aziwenzi umsebenzi ube lula. Lokhu kuyiqiniso ikakhulukazi ngebhande lesikhathi. Ama-shaft amabili asho amabhande amade, futhi ububanzi bama-pulleys buba buncane futhi buba buncane, bonga isikhala. Futhi-ke, zonke izingxenye kufanele zibe nesisindo esincane ngangokunokwenzeka.
Impilo yesevisi enconyiwe yamabhande esikhathi namuhla ngokuvamile iyiminyaka eyi-60. kufika ku-150 km. Amabhande aqine ngokwanele ukumelana nama-torque aphezulu, futhi ngenxa yokuqinisa okwengeziwe kwe-fiberglass. Impilo yesevisi yesistimu yebhande ihlale ikalwa ngamakhilomitha aqhutshwayo. Lesi yisici esiyinhloko, kodwa hhayi kuphela. Kukhona ezinye ezimbalwa ezingafinyeza impilo yebhande - okulandelayo okuqinile noma ukungezwani okuxekethile. Okokuqala kubangela ukugqoka nokugxuma kwamazinyo, kanti okwesibili kubangela ukugqoka nokulimala ohlangothini lwebhande, okuholela ekwandeni kokugqoka kuma-rollers nama-bearings. Ukudlidliza, uwoyela, uphethiloli noma ukuvuza kwamanzi, kanye nokugqwala ngezinye izici ezinganciphisa ukuphila kwamasistimu akho.
