I-CVT

I-CVT gearbox (noma i-variator) iyisisetshenziswa esidlulisa amandla ajikelezayo (torque) isuka enjinini iye emasondweni, yehlise noma inyuse isivinini sesondo (i-gear ratio) ngejubane elifanayo lenjini. Impahla ehlukile ye-variator ukuthi ungashintsha amagiya ngezindlela ezintathu:

• ngesandla;
• ngokuzenzakalelayo;
• ngokohlelo lokuqala.

U-gearbox we-CVT uhlala uguquguquka, okusho ukuthi awushintshi usuka kwelinye uya kwelinye ngezitebhisi, kodwa uvele ushintshe ngendlela ehlelekile isilinganiso segiya liye phezulu noma phansi. Lo mgomo wokusebenza uqinisekisa ukusetshenziswa okukhiqizayo kwamandla eyunithi yamandla, ithuthukisa izici eziguqukayo futhi inwebe impilo yesevisi yemishini (isipiliyoni sesikhungo sesevisi seFavorit Motors Group of Companies siqinisekisa lokhu)

Ibhokisi le-variator liyithuluzi elilula, liqukethe izinto ezilandelayo:

• idivaysi yokuvumelanisa injini nebhokisi legiya (lokuqalisa);
• ngokuqondile i-variator ngokwayo;
• idivayisi yokuhlinzeka ngokuhlehla (imvamisa i-gearbox);
• iyunithi yokulawula ngogesi;
• iphampu ye-hydro.

Ezimotweni zesizukulwane sakamuva, izinhlobo ezimbili zama-variators zisetshenziswa kabanzi - i-V-belt ne-toroid.

Izici zokusebenza kwe-V-belt CVT amabhokisi

Ibhokisi le-V-belt le-CVT liyipheya lama-pulleys axhunywe ibhande le-V elenziwe ngerabha enamandla noma insimbi. I-pulley ngayinye yakhiwa ama-disc amabili amise okukhethekile akwazi ukuhambisa futhi aguqule ububanzi be-pulley ngesikhathi sokunyakaza, ukuqinisekisa ukuthi ibhande lihamba ngokungqubuzana okungaphezulu noma okuncane.

I-variator ye-V-belt ayikwazi ukuhlinzeka ngokuzimele (ukushayela okuphambene), njengoba ibhande lingakwazi ukuzungeza ohlangothini olulodwa. Ukuze wenze lokhu, ibhokisi le-V-belt variator lifakwe idivayisi yegiya. I-gearbox iqinisekisa ukusatshalaliswa kwamandla ngendlela yokuthi ukunyakaza endaweni "emuva" kungenzeka. Futhi imojula yokulawula i-elekthronikhi ivumelanisa ububanzi bama-pulleys ngokuhambisana nokusebenza kweyunithi yamandla.

Izici zokusebenza kwamabhokisi e-toroidal CVT

I-Toroidal variator ngokwesakhiwo iqukethe ama-shaft amabili anomumo we-toroidal. Ama-shafts angama-coaxial maqondana nomunye nomunye, futhi ama-roller aboshwe phakathi kwawo. Ngesikhathi sokusebenza kwebhokisi, ukwanda / ukwehla kwesilinganiso segiya kwenzeka ngenxa yokunyakaza kwama-roller ngokwawo, ashintsha isikhundla ngenxa yokunyakaza kwama-shafts. I-torque idluliswa ngenxa yamandla okungqubuzana okwenzeka phakathi kobuso be-shafts nama-roller.

Kodwa-ke, ama-gearbox we-toroidal CVT awavamile ukusetshenziswa embonini yezimoto yesimanje, ngoba awanakho ukwethembeka okufanayo nakwesimanjemanje se-V-belt.

Imisebenzi yokulawula ngogesi

Ukulawula i-CVT, imoto ifakwe uhlelo lwe-elekthronikhi. Isistimu ikuvumela ukuthi wenze imisebenzi eminingana:

• ukwanda / ukwehla kwesilinganiso segiya ngokuhambisana nemodi yokusebenza kweyunithi yamandla;
• ukulawulwa kokusebenza kwe-clutch (endimeni lapho isiguquli se-torque ngokuvamile sisebenza);
• ukuhlelwa kokusebenza kwebhokisi lamagiya (ukubuyisela emuva).

Umshayeli ulawula i-CVT esebenzisa i-lever (isikhethi). Ingqikithi yokulawula icishe ifane nezimoto ezine-othomathikhi: udinga nje ukukhetha umsebenzi (ukushayela phambili, ukushayela emuva, ukupaka, ukulawula okwenziwa ngesandla, njll.).

Izincomo zokusebenza kwama-variators

Ongoti beFavorit Motors Group of Companies bayaqaphela ukuthi amabhokisi e-CVT awakulungele ukuthutha impahla ngenxa yokwenyuka kwemithwalo enjinini. Nokho, ububanzi besicelo sabo ezimotweni zabagibeli kunekusasa eliqhakazile, njengoba ukudluliswa okuguquguqukayo okuqhubekayo kulula futhi kulula ngangokunokwenzeka kubashayeli.

Ngesikhathi esifanayo, awekho amathiphu athile abanikazi bezimoto ezine-CVT. Imoto izizwa kahle emigwaqweni yedolobha nangaphandle komgwaqo, ngoba ukwehla / ukwanda kwejubane kubushelelezi ngangokunokwenzeka.

Kodwa-ke, njenganoma yiluphi uhlobo lokudlulisela, izici ezimbili zizothinta impilo ye-variator: isitayela sokushayela kanye nokushintshwa okufika ngesikhathi koketshezi olusebenzayo. Ngesikhathi esifanayo, kubalulekile ukugcizelela okuyingqayizivele kokugcinwa kwe-variator: uma imoto isebenza kuphela ezimweni zasemadolobheni, khona-ke ukuguqulwa kwamafutha akudingekile. Lapho ushayela ngaphandle komgwaqo, ngama-trailer noma emgwaqeni omkhulu ngesivinini esikhulu, abakhiqizi beluleka ngokushintsha uwoyela ngemuva kwamakhilomitha ayizinkulungwane ezingama-70-80.

Abanikazi bezimoto ezine-CVT (V-belt version) bayazi ukuthi ibhande lidinga ukushintshwa ngemva kwamakhilomitha ayizinkulungwane ezingu-120. Ngisho noma kungekho ukukhubazeka okubonakalayo ngesikhathi sokusebenza kwemoto, kufanele ucabange ngokucophelela le nqubo, ngoba ukunganaki ukufaka esikhundleni sebhande kungabangela umonakalo ebhokisini.

Izinzuzo ze-variator ngaphezu kwezinye izinhlobo zokudlulisela

I-CVT namuhla ibhekwa njengohlobo "oluthuthukisiwe" kakhulu lokudlulisela. Kunezizathu eziningi zalokhu:

• ukushintsha okushelelayo kwesilinganiso segiya kunikeza amandla angcono lapho uqala noma usheshisa;
• ukonga kokusetshenziswa kukaphethiloli;
• ukugibela okulinganayo futhi okubushelelezi;
• akukho ukwehla ngisho nangesikhathi sokukhuphuka okude;
• ukugcinwa okungenasidingo (umklamo ulula kakhulu, unesisindo esingaphansi, isibonelo, ukudluliswa okuzenzakalelayo okuzenzakalelayo).

Namuhla, inani elandayo labakhiqizi bezimoto bethula ama-CVT ezimotweni. Isibonelo, imboni ye-Ford inentuthuko yayo kule ndawo, ngakho-ke isizukulwane esisha sezimoto sikhiqizwa nge-brand Ecotronic noma i-Durashift CVT.

Ukucaciswa kokusebenza kwe-CVT nakho kulele eqinisweni lokuthi lapho ushintsha isilinganiso segiya, umsindo wenjini awushintshi, okungeyona ejwayelekile kwezinye izinhlobo zokudlulisela. Nokho, abanye abakhiqizi ezinhlotsheni zakamuva ze-CVTs baqale ukusebenzisa umphumela wokwanda komsindo wenjini ngokuhambisana nokwanda kwejubane lemoto. Phela iningi labashayeli sebejwayele ukushintsha umsindo wenjini ngamandla enyuka.

Umnikazi wemoto ngamunye ukhetha imoto ngokusekelwe kulokho akuthandayo, izidingo namandla ezezimali. Izimoto ezine-CVT zibonakala ngokuthembeka nokwanda kokumelana nokugqokwa, kodwa ubuchwepheshe obusha buyabiza kakhulu. Ungakwazi ukukhetha ngokushesha imoto ngokuvumelana nezifiso zakho kanye namathuba uma ukhetha indawo yokuthengisa izimoto efanele. I-Favorit Motors Group of Companies inikeza izinhlobonhlobo eziningi zamamodeli avela kubakhiqizi abahlukene ngamanani angabizi.

Amasevisi emoto aqinisekisiwe kuphela angenza ukuxilonga, ukukhanda nokulungiswa kwe-variator. Ochwepheshe besikhungo sezobuchwepheshe se-Favorit Motors banazo zonke izinto ezidingekayo zokuxilonga nokulungisa ezitholakalayo, ezibavumela ukuba baqede ngokushesha nangesikhathi esifushane ukungasebenzi kahle kwe-variator yanoma yikuphi ukuguqulwa.

Abaphathi abanolwazi be-Favorit Motors bazokwenza ukuxilongwa kwekhwalithi ephezulu ye-variator, baqinisekise izimbangela zokungasebenzi kahle futhi bakuqede. Futhi, ngaphezu kwalokho, bazokweluleka ngokusebenza kahle kwe-gearbox ye-CVT. Inqubo yokulungisa kuvunyelwana ngayo neklayenti, futhi izindleko zokulungisa nokubuyisela zimenyezelwa ngemva kokuxilongwa.
