Puas yog koj lub Corolla ua Pop thaum nws mus dhau lub pob nrawm? 90% Ntawm Lub Sijhawm, Nws Yog Vim Lub Cev Tswjhwm xav tau hloov.

Puas yog koj lub corolla ua "pop" thaum nws hla lub pob nrawm? 90% ntawm lub sij hawm, nws yog vim hais tias tus tswj caj npab yuav tsum tau hloov.
"Thuckle-"
Txhua zaus koj hla kev nrawm nrawm, koj hnov ​​​​lub suab nrov ntawm lub chassis. Koj lub siab sib tw, tab sis lub tsheb tseem tsav tau, yog li koj tsis quav ntsej txog nws.
Nres. Tsis txhob ncua.
90% ntawm lub sijhawm, lub suab taw qhia rau tib qhov chaw, sab caj npab tswj qis.
Niaj hnub no peb coj lub Corolla ua piv txwv los pab koj to taub qhov twg lub suab tuaj, nws loj npaum li cas, seb nws yuav tsum tau hloov thiab qhov twg yuav tsum tau hloov.
Ua ntej, cia peb paub meej: "jingling" yog dab tsi?
Thaum Corolla tshaj qhov nrawm nrawm, lub log yuav cuam tshuam txog li 2-3 npaug ntawm qhov hnyav ntawm lub tsheb. Qhov kev quab yuam no raug xa mus los ntawm lub log tsheb mus rau lub kauj tsheb kauj vab thiab tom qab ntawd mus rau lub pob sib koom ntawm lub caj npab tswj.
Feem ntau, lub pob taub hau thiab bushing nqus lub zog, thiab txhua yam koj tuaj yeem hnov ​​​​yog "thud."
Nyob rau hauv tej yam txawv txawv, yog hais tias lub pob taub hau los xoob los yog bushing so, lub zog yuav untenable thiab crisp "clang" yog ua raws li cov hlau collides nrog hlau.
Yooj yim tso: "Bam" yog koj txhais caj npab tswj koj qhia rau koj -"Kuv tuav tsis tau lawm."
ii. Vim li cas lub caj npab tswj thiab tsis yog tus so?
Ntau Ntau Ntau tus neeg thawj cov tshuaj tiv thaiv yog: "Puas yog qhov poob siab absorber tawg?"
Tsis tas li. Cia peb siv cov txheej txheem tshem tawm:
Yog tias muaj teeb meem nrog lub shock absorber (coil brake), koj yuav hnov ​​​​ib lub suab "humming" aftershock thiab lub tsheb yuav co ob lossis peb zaug thaum nws hla lub damper ua ntej nres. Qhov no yog hu ua "inadequate damping."
Yog tias koj muaj teeb meem nrog cov springs, koj tuaj yeem hnov ​​​​tias lub cev poob qis lossis ib sab siab dua lwm qhov. Qhov no yog hu ua "caij nplooj ntoos hlav tsaug zog."
Yog hais tias lub stabilizing bar txuas (stirrup mechanism) yog ib qho teeb meem, lub suab feem ntau tshwm sim thaum lub kaum sab xis, lub suab "creaking" uas tsis muaj feem cuam tshuam txog kev hla kev nrawm nrawm.
Yog hais tias qhov teeb meem yog nrog tus tswj caj npab, txawm li cas los xij, lub suab yog qhov tshwj xeeb: "clunk" ntawm kev nrawm nrawm, "thud" ntawm lub pas dej thiab "nias" thaum lub kauj tsheb tig tag nrho. Yog tias koj hnov ​​​​ib qho ntawm peb lub suab, nws yuav luag yog tus tswj caj npab.
Tshwj xeeb tshaj yog nyob rau hauv tsev neeg lub tsheb zoo li Corolla, qhov twg chassis Cheebtsam ua los ntawm siab -lub zog steel es tsis yog aluminium alloy, pob pob qij txha thiab bushings hnav sai dua li koj xav. Tom qab 80,000 txog 120,000 mais, lub caj npab tswj yog thawj feem kom ncav cuag nws lub neej muaj txiaj ntsig.
III. Lub caj npab tswj puas txaus ntshai npaum li cas?
"Ntau tus neeg xav tias,"Nws yog suab nrov xwb, nws tsis zoo li kuv tsav tsis tau."
Qhov no yog qhov yuam kev loj heev.
Qhov tsis ua haujlwm ntawm kev tswj caj npab tau muab faib ua peb theem, txhua qhov txaus ntshai tshaj qhov kawg:
Theem 1: Kev laus hav txwv yeem (80,000km txog 100,000km)
Cov roj hmab bushing hardens thiab tawg, thiab cov pob qij txha pib ua si. Cov tsos mob muaj xws li lub suab "clunk" "thaum dhau qhov nrawm nrawm nrawm thiab me ntsis" xoob "lub kauj" ntawm lub kauj.
Koj tseem tuaj yeem tsav tsheb ntawm theem no, tab sis nws muab lus ceeb toom rau koj. Yog tias koj tsis hloov nws, nws yuav kav ntev li 10,000 txog 20,000 km.
Theem 2: Pob hnav (100,000km txog 140,000 km)
Lub suab ntawm lub log pib hloov raws li qhov sib txawv ntawm lub pob steel ntawm lub pob thiab lub khob. Cov tsos mob muaj xws li cov log tsheb tsis sib xws (cov log tsheb sab hauv lossis sab nrauv hnav sai dua), kev kub ceev lub kauj tsheb vibration thiab pom qhov nce hauv lub cev yob thaum lub kaum sab xis.
Qhov no yog theem txaus ntshai heev. Lub pob tuaj yeem poob thaum twg los tau. Yog tias lub tsheb mus nrawm dhau, lub log yuav tig tawm ntawm kev tswj hwm thiab qhov tshwm sim yuav muaj kev puas tsuaj.
Theem 3: Tswj caj npab Deformation lossis pob txha tawg (ntau dua 140,000 km, lossis txuas ntxiv mus rau theem 2 yam tsis hloov pauv)
Tsis txhob tsav tsheb ntawm theem no, hu rau lub tsheb thauj khoom thauj.
Yog li, yog tias koj tsis quav ntsej hnub no, "Ding Dong" yuav dhau los ua "Pop" tag kis.
IV. QHOV CHAW UA HAUJ LWM Vim li cas Corolla cov caj npab tswj tshwj xeeb yog qhov tsis zoo? Qhov no tsis yog vim qhov zoo ntawm Corolla, tab sis vim nws qhov kev tsim qauv tsim.
Lub Corolla yog tsev neeg lub tsheb uas tau muag ntau tshaj 50 lab lub tsheb thoob ntiaj teb. Nws chassis tsim qhov tseem ceeb "zoo txaus tus nqi rau cov nyiaj."
Raws li qhov tshwm sim, nws txhais caj npab tswj yog ua los ntawm siab - lub zog steel ib leeg - daim stamped qhov chaw, es tsis yog aluminium alloy lossis forging. Qhov zoo ntawm cov qauv steel yog tus nqi qis thiab ua haujlwm ntev, tab sis qhov tsis zoo yog qhov hnyav dua thiab qaug zog lub neej kwv yees li 30% luv dua aluminium alloys.
Tom qab ntawd muaj Corolla qhov chaw tsav tsheb hauv Suav teb: txoj kev hauv nroog tsis zoo, kev nrawm nrawm, hnyav dhau thiab kev saib xyuas tsis tu ncua-tag nrho cov no, coj los ua ke, feem ntau ua rau tswj caj npab ntev dua li lawv tau tsim lub neej.
Tsim kom dhau 150,000 km, nws tsuas yog siv 80,000 txog 100,000 mais thiab tej zaum yuav xav tau hloov.
Nws tsis yog lub tsheb nws tus kheej, nws yog qhov chaw tsav tsheb. Txij li thaum koj hloov tsis tau txoj kev, koj yuav tsum hloov nws thaum ntxov.
V. Hloov riam phom tswj: ib lossis ob txhais caj npab?
Nov yog cov lus nug uas nquag nug.
Teb: Peb xav kom hloov ob qho tib si.
Qhov laj thawj yog qhov yooj yim: tswj riam phom hauv khub. Lub zog ntawm sab laug thiab sab xis yog qhov sib npaug, thiab lawv cov nqi hnav zoo li qub. Yog tias koj hloov ib qho tshiab, qhov qub tseem yuav "jingle," tsis yog tsuas yog luv luv lub neej ntawm qhov tshiab, tab sis kuj ua rau lub log tsis sib xws vim qhov tsis sib xws ntawm cov duab kos.
Nco ntsoov: hloov ib qho zoo li hloov tsis muaj dab tsi; hloov tag nrho khub daws qhov teeb meem.
Rau Corolla, ib khub ntawm caj npab tswj qis yog suav nrog:
Sab xis (sab neeg nrog caij): 48068-12290
Sab laug (tus tsav tsheb): 48069-12290
Yuav ua ke, nruab ib zaug, txuag lub sijhawm thiab kev siv zog.
VI. INTRODUCTION Tus Kheej-Kev ntsuam xyuas: Koj puas yuav tsum tau hloov koj txhais caj npab tswj?
Tsis tas yuav mus rau lub khw 4S tsuas yog kuaj xyuas sai tom tsev:
Kauj Ruam 1: Kom ib tug neeg tuav lub hauv ntej ntawm lub tsheb. Squat down, tuav lub caj npab tswj qis ze ntawm lub pob sib koom, thiab thawb thiab rub. Yog tias muaj lub viav vias pom zoo (ntau dua 2 hli viav vias), cov pob qij txha yuav xoob thiab yuav tsum tau hloov.
Kauj Ruam 2: Ci lub teeb nyem ntawm lub bushing txuas tus tswj caj npab mus rau tus ncej. Yog tias pom muaj kab nrib pleb, bulges los yog roj leaks nyob rau hauv cov roj hmab, lub bushing yuav hnav thiab yuav tsum tau hloov.
Kauj Ruam 3: Tshawb xyuas cov log tsheb. Yog tias cov log tsheb sab laug thiab sab xis hnav tsis zoo (ib qho sab hauv thiab sab nraud), qhov no txhais tau hais tias lub caj npab tswj deforms, ua rau muaj kev hloov ntawm lub kaum sab xis thiab yuav tsum tau hloov.
Yog tias ib qho ntawm peb kauj ruam no siv tau, tsis txhob yig los hloov nws.
VII. Thaum kawg, ib lo lus zoo siab: lub caj npab tswj tsis yog "pom tseeb" li cov pawm nres, thiab nws tsis cuam tshuam li "ntau zaus" raws li cov roj cav. Nws zaum ntsiag to ntawm lub chassis, thiab koj yeej tsis paub txog thaum koj muab nws cais tias nws nyob ze qhov kawg.
Tab sis thaum nws tawg lawm, nws yog qhov tseeb qhov "tseem ceeb" uas yog qhov teeb meem tseem ceeb.
Muaj ib tug "clunk," tsis yog lub suab ntawm lub tsheb hlub, tab sis ib tug quaj thov kev pab.
