Cov Lus Qhia rau Kev Xaiv Hom Roj Hmab Kis Zoo
Cov kua roj kis tau yog ib qho tseem ceeb heev rau kev tswj hwm kev ua haujlwm thiab lub neej ntev ntawm lub tsheb lub zog kis tau. Ob lub tsheb thiab maus taus ua haujlwm nyob rau hauv qhov siab siab, kev sib txhuam, thiab qhov kub thiab txias. Yog tsis muaj cov kua roj zoo, kev hloov iav tuaj yeem ua rau tsis zoo, cov khoom siv hnav sai, thiab suab nrov tuaj yeem tshwm sim, ua rau muaj kev puas tsuaj loj thiab kim heev. Yog li ntawd, kev xaiv hom kua roj kis tau zoo tsis tuaj yeem ua tiav los ntawm "thov roj," tab sis los ntawm kev kho nws kom haum rau lub tsheb cov kev xav tau.
Tsab xov xwm no tham txog cov lus qhia rau kev xaiv cov roj nplua nyeem rau kev sib kis, nws cov hom, cov lus qhia tshwj xeeb uas yuav tsum tau them sai sai, thiab cov cwj pwm uas yuav tsum tau zam.
1. Paub Koj Lub Tsheb Hom Kis
Kauj ruam thawj zaug yog nkag siab txog hom kev sib kis uas siv, vim txhua tus xav tau cov roj nplua nyeem sib txawv.
1. Kev Kis Tes (MT)
Feem ntau siv cov roj iav lossis roj kis tau uas muaj qhov viscosity tshwj xeeb. Cov roj nplua nyeem yuav tsum muaj peev xwm tiv thaiv cov iav kis tau, cov synchronizers, thiab cov bearings kom tsis txhob puas.
2. Kev Kis Tsis Siv Neeg Ib txwm muaj (AT)
Siv ATF (Automatic Transmission Fluid), uas yog "hydraulic" ntau dua li roj iav, ATF tsis yog tsuas yog ua lub roj nplua nyeem xwb tab sis kuj yog lub zog xa mus los ntawm lub converter torque thiab hydraulic pressure controller.
3. CVT (Kev Sib Kis Hloov Pauv Tsis Tu Ncua)
Yuav tsum muaj cov kua CVT tshwj xeeb. Nws cov yam ntxwv lubricating txawv vim nws yuav tsum txhawb nqa kev ua haujlwm ntawm txoj siv sia/saw thiab pulleys, tswj kev sib txhuam, thiab tswj qhov kub thiab txias kom ruaj khov.
4. DCT (Kev Sib Kis Ob Lub Clutch)
Muaj DCTs "ntub" (clutch uas muaj kua) thiab DCTs "qhuav". DCTs ntub feem ntau siv cov kua tshwj xeeb uas muaj peev xwm txias thiab tswj kev sib txhuam rau lub clutch. DCTs qhuav feem ntau muaj cov lus qhia sib txawv thiab tsis tas li siv tib cov kua.
5. Tsav Tsheb Kawg / Kev Sib Kis Sib Txawv
Hauv cov tsheb tsav log tom qab lossis 4WD, lub qag siv roj iav nrog qee cov lus qhia API GL, qee zaum nrog kev ntxiv cov khoom siv txwv rau LSD.
Yog koj tsis paub meej txog koj hom kis tau tus mob, mus saib phau ntawv qhia rau koj tus tswv lossis daim ntawv lo rau ntawm lub cav/chav pabcuam. Kev kwv yees yuav ua rau muaj kev sau tsis raug.
2. Nkag Siab Txog Lub Luag Haujlwm ntawm Cov Roj Hmab Kis
Cov roj nplua nyeem rau kis tau ntau tshaj li txo qhov kev sib txhuam xwb. Nws cov haujlwm suav nrog:
- Siv roj nplua nyeem rau cov iav thiab cov khoom txav mus los kom tiv thaiv kev hnav sai.
- Txias los ntawm kev nqa cua sov tawm ntawm thaj chaw sib cuag.
- Ntxuav los ntawm kev khi cov khoom me me thiab cov deposits.
- Tiv thaiv kev xeb ntawm cov khoom hlau.
- Tswj kev sib txhuam (tshwj xeeb tshaj yog AT, CVT, thiab DCT) kom kev hloov pauv fais fab du thiab tsis plam.
Vim tias qhov kev sib txhuam no muaj nuj nqi tshwj xeeb heev, tshwj xeeb tshaj yog nyob rau hauv cov kis tau tus mob tsis siv neeg, kev xaiv cov kua tsis raug tuaj yeem ua rau muaj cov tsos mob xws li plam, co, lossis kub dhau.
3. Ua raws li Cov Lus Qhia ntawm Chaw Tsim Khoom (Qhov Chaw Nyab Xeeb Tshaj Plaws)
Lub tswv yim tseem ceeb tshaj plaws: ua raws li cov lus qhia ntawm cov chaw tsim khoom. Phau ntawv qhia feem ntau hais tias:
– Hom kua uas xav tau (piv txwv li, ATF tshwj xeeb, CVT kua tshwj xeeb)
– Cov qauv kev qhia tshwj xeeb (piv txwv li Dexron, Mercon, JASO, lossis cov lej tshwj xeeb ntawm cov chaw tsim khoom)
- Lub peev xwm thiab lub sijhawm hloov pauv
Muaj tej hom tsheb uas muaj lawv cov lus qhia txog ATF (piv txwv li, Toyota T-IV/WS, Honda ATF DW-1, Nissan Matic, thiab lwm yam). Txawm hais tias muaj cov khoom "ntau lub tsheb" nyob rau hauv kev ua lag luam, xyuas kom meej tias qhov sib xws yog qhov tseeb.
4. Tshawb xyuas cov qauv thiab cov lej qhia tshwj xeeb (API, GL, Dexron, thiab lwm yam)
Nov yog qee cov qauv uas feem ntau ntsib:
Rau qhov kev sib kis tes thiab qag (roj iav)
– API GL-4: Feem ntau haum rau kev hloov pauv tes uas siv cov tooj dag synchronizers.
– API GL-5: Muaj peev xwm siab dua (EP), feem ntau siv rau cov qag. Txawm li cas los xij, nyob rau hauv qee qhov xwm txheej, GL-5 yuav tsis haum rau qee qhov kev sib kis tes vim tias EP additive tuaj yeem cuam tshuam rau lub synchronizer.
– SAE 75W-90, 80W-90, 75W-80, thiab lwm yam: Qhia txog qib viscosity.
Rau kev sib kis tsis siv neeg
– Dexron (II, III, VI): Tus qauv dav dav ATF rau ntau lub tsheb, tab sis tseem yuav tsum phim cov lus qhia ntawm cov chaw tsim khoom.
– Mercon: Tus qauv ATF uas siv dav hauv qee lub tsheb.
– ATF tshwj xeeb rau cov chaw tsim khoom: Feem ntau muaj cov khoom siv sib txhuam uas tsim los rau cov yam ntxwv hloov iav tshwj xeeb.
Rau CVT
– Cov kua CVT tsis tuaj yeem piv rau ATF ib txwm muaj. CVTs xav tau cov yam ntxwv sib txawv ntawm kev sib txhuam kom tiv thaiv txoj siv sia/saw plam thiab tiv thaiv kev puas tsuaj ua ntej lub sijhawm.
Rau DCT
– Cov kua DCT feem ntau muaj nws tus lej. Tsis txhob hloov nws nrog ATF ib txwm tsuas yog tias lub chaw tsim cov roj nplua nyeem hais meej meej txog kev sib haum xeeb.
5. Ua tib zoo saib xyuas qhov viscosity thiab kev siv.
Qhov viscosity tuab dhau ua rau kev hloov iav nyuaj thaum huab cua txias, thaum qhov viscosity nyias dhau ua rau kev tiv thaiv tsis zoo thaum kub siab. Yog li ntawd:
– Rau cov huab cua ib txwm thiab kev siv, ua raws li tus qauv viscosity ntawm cov chaw tsim khoom.
- Yog siv hnyav (xws li rub, nce toj heev, thauj khoom ntau), xaiv cov khoom uas tsis hloov pauv raws li cov lus qhia tshwj xeeb tab sis ruaj khov rau qhov kub thiab txias.
– Rau cov tsheb qub, qee tus neeg xav siv cov roj nplaum tuab dua los "txo qhov suab nrov." Qhov no yuav pab tau ib ntus, tab sis nws yuav ua rau cov synchronizers ua haujlwm hnyav dua thiab kev siv roj nce mus. Zoo dua xyuas qhov chaw ntawm qhov teeb meem.
6. Xaiv Cov Roj Mineral, Semi-Synthetic, lossis Full Synthetic?
Feem ntau:
– Cov khoom siv hauv av: Pheej yig dua, txaus rau kev siv ib txwm thiab tsis siv sijhawm ntev dhau.
– Semi-synthetic: Kev sib haum xeeb ntawm tus nqi thiab kev ua tau zoo, feem ntau ruaj khov dua thaum kub.
– Cov roj ua los ntawm cov khoom siv tag nrho: Zoo dua tiv taus oxidation, ruaj khov ntawm qhov kub siab thiab qis, haum rau kev ua haujlwm siab lossis lub sijhawm ntev dua (tseem ua raws li cov lus qhia ntawm cov chaw tsim khoom).
Tiam sis nco ntsoov tias, "kim dua" tsis tau txhais hais tias "haum dua." Qhov tsim nyog tseem txiav txim siab los ntawm cov lus qhia tshwj xeeb.
7. Ceev faj txog cov khoom "Universal" uas tsis meej
Muaj ntau cov roj nplua nyeem hauv khw uas hais tias siv tau rau ntau hom kev sib kis. Tsis yog txhua yam phem, tab sis koj yuav tsum ua raws li cov hauv qab no:
– Nyeem daim ntawv qhia txog cov ntaub ntawv kev siv yog tias muaj
- Xyuas kom meej tias muaj daim ntawv teev npe sib xws meej
- Tsis txhob siv cov khoom uas tsuas yog ua raws li cov lus hais txog kev lag luam xwb yam tsis muaj cov qauv qhia meej.
Rau CVTs thiab DCTs, nws yog qhov zoo tshaj plaws kom ceev faj dua: siv cov khoom uas hais txog cov lus qhia tsim nyog.
8. Xav txog lub sijhawm hloov pauv thiab cov tsos mob ntawm kev puas tsuaj
Cov kua kis tau kuj laus zuj zus: cov khoom ntxiv hnav tawm, viscosity hloov pauv, muaj kuab paug rau cov khoom me me, thiab kev ua haujlwm sib txhuam poob qis. Qee cov cim qhia uas yuav tshwm sim suav nrog:
- Hloov iav tsis zoo los yog lig (AT/CVT)
- Lub suab nrov nrov / lub suab snoring (phau ntawv / qhov sib txawv)
- Kev co thaum lub sijhawm acceleration (CVT)
- Xim ATF tsaus zuj zus thiab muaj ntxhiab kub hnyiab (qhia tias kub dhau lawm)
Txawm hais tias lawv hais tias "kua roj siv tau mus ib txhis," hauv kev xyaum, ntau tus kws kho tshuab tseem pom zoo kom hloov cov kua roj tsis tu ncua, tshwj xeeb tshaj yog thaum siv ntau dhau. Ib txwm saib cov lus qhia ntawm cov nom tswv thiab qhov xwm txheej tiag tiag ntawm lub tsheb.
9. Tsis txhob sib tov cov roj nplua nyeem sib txawv yam tsis saib xyuas.
Kev sib xyaw ob lub kua dej uas muaj cov yam ntxwv sib txawv tuaj yeem hloov pauv lawv cov yam ntxwv sib txhuam thiab cov yam ntxwv ntxiv. Cov teebmeem tuaj yeem suav nrog:
- Kev sib txhuam ntawm AT/DCT clutch
- Kev ua haujlwm ntawm CVT poob qis
- kev tsim cov sludge
Yog tias koj yuav tsum ntxiv ntau dua, sim ntxiv cov khoom qub. Yog tias koj tsis paub meej, nws muaj kev nyab xeeb dua los hloov nws siv cov txheej txheem raug.
10. Siv Cov Txheej Txheem Sau Kom Yog
Hauv cov tsheb kis tau tus kheej niaj hnub no , cov qib ATF tsis tas li siv lub dipstick los ntsuas. Muaj cov txheej txheem kub ua haujlwm tshwj xeeb, qhov chaw ntawm lub lever, thiab cov txheej txheem overflow. Cov qib tsis raug tuaj yeem ua rau tuag taus:
- Tsis muaj zog: hydraulic siab poob qis, plam, kub sai sai
- Ntau dhau: aeration/ua npuas dej, siab tsis ruaj khov, teeb meem hloov iav
Yog tias koj tsis tau siv rau nws, qhov zoo tshaj plaws yog kom ua nws ntawm lub chaw ua haujlwm uas nkag siab txog cov txheej txheem rau lub tsheb ntawd.
