Abin da za a zaba: bambance-bambance ko atomatik

Ana iya wakiltar watsa ta atomatik ta akwatin gearbox, fasalin atomatik na yau da kullun da kuma mai bambanta. Lokacin siyan mota, mai sha'awar mota yana tunanin wane akwatin gearbox ne zai ba da fifiko; wanne ya fi kyau: mai banbanci ko watsawa ta atomatik. Lokacin zabar tsakanin mai bambance-bambancen da na'ura na atomatik, kuna buƙatar sanin yadda suka bambanta, la'akari da fa'idodi da cutarwa, kuma kuma fahimci wanne daga cikin na'urorin ya fi aminci.

Watsa CVT

Kamar kowane gearbox, mai bambance-bambancen abu shine na'urar da ke jujjuya karfin juyi daga injin zuwa ƙafafun. Rarraba karfin juyi ana aiwatar da shi cikin tsari a cikin takamaiman kewayon sarrafawa. Mafi yawan lokuta, ana sanya mai bambance-bambance ta taƙaitaccen "CVT" (Ci gaba da Canza Musamman), wanda aka fassara daga Ingilishi yana nufin “watsawa tare da ci gaba da sauya karfin juyi”.

Nau'in CVT

Dogaro da na'urar, ana bambanta manyan nau'ikan masu bambance-bambancen:

• sarka;
• V-bel;
• toroidal.

V-bel CVT wanda aka fi amfani dashi.

V-bel CVT yana ƙunshe da bel na V wanda yake tsakanin zoben juzu'i biyu. A yayin motsi na motar, ana matsa abubuwa, sannan ba a sanya su ba, suna ba da canji a cikin yanayin gear. Babban mahimmancin CVT shine don samar da canji mai sauƙi, mara ƙarfi. Wannan gaskiyane ga motoci, babura, motocin kankara da sauran kayan aiki.

A cikin sabanin silsilar CVT, ana watsa karfin ne ta hanyar karfin sarkakiyar mahada, kuma ana daukar karfin jan abu ta hanyar sarkar.

A cikin masu jujjuyawar toroidal, maimakon juzu'i, ana amfani da fayafai da aka ɗauka, maimakon bel, rollers. Suna da ikon watsa ƙarin karfin juyi. Don ƙera sassa don wannan nau'in CVT, ana buƙatar ƙarfe mai ƙarfi, wanda ƙarshe yana shafar farashinsa.

Fa'idodi da rashin amfani na CVT

Babban fa'idar watsa CVT shine ikon samar da ci gaba da canji a cikin juzu'i. Wannan yana ba da damar ingantaccen amfani da mai da kuzarin abin hawa.

Rashin dacewar mai bambancin sun hada da:

1. Rashin ikon girka shi a cikin motoci tare da injin mai ƙarfi.
2. Matsakaicin lodi, jan kaya ko tuki na yau da kullun a manyan canje-canje zai haifar da saurin lalacewa na belin bambance-bambancen, kuma, daidai da, lalacewar CVT.

Watsa kai tsaye

Ana zaɓar watsa atomatik ta mai zaɓin motsi wanda yake kan rami na tsakiya ko a kan shafi na tuƙi (a cikin motocin Amurka). Matsar da mai zaben zuwa wani matsayi yana baka damar zabar yanayin tuƙin da kake so. Bugu da ƙari, yana yiwuwa a zaɓi hanyoyin aiki na musamman na watsa atomatik: hunturu, wasanni, tattalin arziki. Bambancin amfani da mai tsakanin al'ada, wasanni da yanayin tattalin arziki a bayyane yake.

Tsarin watsa shirye-shiryen ta atomatik ya ƙunshi gearbox na duniya, tsarin sarrafawa da mai sauya juzu'i. Ana iya amfani da inji a cikin motoci, manyan motoci da kuma bas.

Mai jujjuyawar juyi ya ƙunshi fanfo da ƙafafun turbin tare da mai sarrafawa wanda ke tsakanin su. An haɗa dabaran famfo zuwa ƙwanƙwasa injin, an haɗa kewayen turbine zuwa maɓallin gearbox. Mai sarrafawa, gwargwadon yanayin aiki, yana juyawa da yardar kaina ko an toshe shi ta hanyar ɓoye kama.

Rarraba karfin juyi daga injin zuwa gearbox yana faruwa ne ta kwararar ruwa (mai) wanda iska mai wutsiya akan wukake ruwan wukake. Ratarorin da ke tsakanin impeller da turbine kaɗan ne, kuma raƙuman ruwan suna da takamaiman fasali wanda ke samar da ci gaba da zagayen mai. Don haka, babu wata mahaɗan mahaɗa tsakanin injin da watsawa, wanda ke ba da gudummawa ga sassauƙan watsa ƙoƙarin ƙoƙari.

Mai jujjuyawar juyi yana juya saurin juyawa da karfin juzuwar da aka watsa a cikin iyakantaccen iyaka, sabili da haka an haɗa gearbox na duniya da yawa a ciki. Hakanan yana samar da motsi baya.

Kwatanta halaye na nau'i biyu na gearboxes

Wace na'urar ce ta fi kyau: CVT ko atomatik? Bari muyi kwatancen kwatankwacin da zai baku damar gano bambance-bambance kuma ku tantance wanene daga cikin akwatunan da yafi kyau kuma mafi aminci.

Bambanci tsakanin bambance-bambancen da na'ura ta atomatik daga mahangar tattalin arziki

Wani akwatin gearbox ya fi kyau dangane da farashin aiki: CVT ko atomatik? Bari mu gwada wasu alamun.

1. Ruwan watsawa. Canje-canjen mai na CVT sun fi yawa kuma sun fi tsada.
2. Amfani da mai. Man fetur a cikin mota sanye take da mai bambance-bambancen ya fi tattalin arziƙi.
3. Gyarawa. Kulawa da gyaran bambance-bambancen ya fi tsada fiye da sarrafa inji. CVT ingantaccen tsari ne mai ma'ana.

Kodayake ya fi tsada don kula da CVT, akwatin kansa ya fi na'ura arha. Kuma tare da yin amfani da kwalin da kyau, zai iya ɗaukar dogon lokaci ba tare da gyara ba.

Wace na'ura ce tafi dacewa dangane da aminci

Don ƙayyade matsayin amincin na'urori, mun saita yanayi masu wahala da yawa:

• yiwuwar jan kaya;
• kashe-hanya;
• babban gudu;
• wasanni hawa.

Mai bambance-bambancen ba zai iya jimre wa yanayi mai wahala ba. Belt dinsa ba zai jure damuwa ba. Gun mashin din zaiyi kyau anan. Sakin CVT - motsi mai sauƙi ba tare da saurin hanzari ba.

Yadda ake tantance wane na'urar da aka sanya a cikin motar

1. Wajibi ne don nazarin takaddun fasaha na inji. Sanya bambancin shine CVT, injin atomatik shine AT.
2. Yi gwajin gwaji. Idan an sanya mai bambance-bambancen, to, ba za ku ji sauyawar kaya ba. Za'a iya "sauraren inji" kuma za'a iya sa mata ido ta tachometer. CVT yana aiki a maɓalli ɗaya, an auna. Koyaya, yana yiwuwa cewa akwai yanayi na musamman wanda ke daidaita canje-canje na kaya kuma ya bawa direba damar jin sun canza.

Bari mu taƙaita

A yau, watsa atomatik ya fi na kowa CVTs. Amma na karshen yana da babbar dama. Amfani da atomatik ya fi aminci don amfani a cikin ababen hawa tare da ƙarfi mai ƙarfi da tirela masu ɗaukar hankali. Ta fuskar tattalin arziki, mai bambancin ya fi dacewa.
