Kwenzekani uma imoto enama-automatic transmission izitatela ngesikhathi ushayela
Noma iyiphi imoto ikwazi ukuma lapho ihamba, kungakhathalekile ukuthi hlobo luni luka-gearbox. Kodwa uma nge "mechanics" yonke into icacile kakhulu, khona-ke ngemishini "yezinyawo ezimbili", akuyona yonke into ebushelelezi futhi esobala. Ingosi ye-AvtoVzglyad isitshela ukuthi inkinga efanayo ingaba yini.
Lona kanye iqiniso lokuthi injini yemoto yavele yayeka ukusebenza ekuhambeni kubangela ukudideka ngisho nokwesaba. Ngaphezu kokukodwa umbhali wale migqa uhlangabezane okufanayo. Akukho lutho olujabulisayo ngalokhu, kodwa kubaluleke kakhulu ukuqonda ukuthi ukuwohloka okunjalo kuzoba namiphi imiphumela.
Uma i-gearbox ingumshini, khona-ke inertia yemoto ehambayo ngokusebenzisa i-clutch evaliwe izophendulela i-crankshaft kuze kube yilapho imoto ifika ime ngokuphelele. Ngesikhathi esifanayo, izinqubo zokushiswa kwengxube ye-air-fuel ngeke zenzeke enjini emile, okusho ukuthi ngeke kube nemiphumela emibi yenjini noma i-gearbox.
Hhayi-ke, injini ingakwazi ukumisa, ukusho, ngenxa yokuthi i-valve ye-EGR (i-exhaust gas recirculation) ivalekile noma kunezinkinga zokunikezwa kukaphethiloli ngenxa yokungcola okuqoqwe kugridi yephampu yamafutha.
Futhi kuthiwani "okuzenzakalelayo"? Ngesinye isikhathi, ngenkathi ushayela imoto ene-hydromechanical transmission, umlobeli wakho wanqanyulwa ibhande lesikhathi. Injini yanyakaza izikhathi ezimbalwa, ima ngase ngigingqika eceleni komgwaqo ngaphandle kokuthinta isikhethi esishintshashintshayo. Amasondo okushayela awazange akhiye, ngakho-ke ungakholelwa izinganekwane ezivela kuwebhu. Imoto ngeke indizele emseleni iyodwa, ngeke ilahlekelwe wukulawula, futhi amasondo azoqhubeka nokujikeleza. Iqiniso liwukuthi injini emile ayijikelezi shaft yokufaka ka-gearbox. Akukho futhi ukucindezela ukuthi ipompo likawoyela lidala. Futhi ngaphandle kwengcindezi, "ibhokisi" elizenzakalelayo lizovula "okungathathi hlangothi". Le modi iyasebenza, ake sithi, enkonzweni noma lapho udonsa imoto ngendlela evumelana nezimo.
Ngakho-ke, umonakalo omkhulu, lapho injini igcina, ikwazi ukubangela imoto kumshayeli ngokwakhe. Uma umuntu eqala ukuxabana, angase ngephutha adlulise isikhethi sisuka “ku-drive” siye “sokupaka”. Kulapho-ke uzwa khona umsindo we-metallic. Ingidi yokupaka isiqala ukugiya emazinyweni esondo ku-output shaft. Lokhu kugcwele ukugqoka kwezingxenye zokudlulisela kanye nokwakhiwa kwezinsimbi zensimbi ezizowela emafutheni "ebhokisi". Ezimweni ezimbi kakhulu, i-latch ingase i-jam. Khona-ke imoto iqinisekisiwe ukuya enkonzweni yokulungiswa okubizayo kokudluliselwa. Ngaphezu kwalokho, uzokwenza elolini elidonsayo.
