Nws yog ib qho tsim nyog hais tias cov cim qhia ntawm kev puas tsuaj tuaj yeem yog cov tsos mob ntawm cov teeb meem nrog lwm cov sensors lossis lwm yam khoom ntawm lub tsheb. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua kom tiav kev kuaj mob ntawm lub tsheb siv lub tshuab kuaj kab mob. Nws yog qhov ua tau tias lwm yam kev ua yuam kev cuam tshuam nrog lwm lub tshuab tsheb tau tsim thiab khaws cia rau hauv lub cim xeeb ntawm chav tswj hluav taws xob.

Ua rau lub sensor tsis ua haujlwm

Los ntawm nws tus kheej, qhov ceev sensor raws li Hall nyhuv yog ib qho khoom siv txhim khu kev qha, yog li nws tsis tshua muaj kev ua haujlwm. Feem ntau ua rau tsis ua hauj lwm yog:

• Tshaj kub. Feem ntau, kev sib kis ntawm lub tsheb (ob qho tib si tsis siv neeg thiab siv tshuab, tab sis feem ntau tsis siv neeg kis tau tus mob) warms li ho thaum nws ua haujlwm. Qhov no ua rau lub fact tias tsis tsuas yog lub sensor vaj tse puas, tab sis kuj nws internal mechanisms. Namely, lub microcircuit soldered los ntawm ntau yam khoom siv hluav taws xob (resistors, capacitors, thiab lwm yam). Raws li, nyob rau hauv lub siab kub, lub capacitor (uas yog ib tug magnetic teb sensor) pib luv luv Circuit Court thiab ua ib tug conductor ntawm hluav taws xob tam sim no. Yog li ntawd, lub sensor ceev yuav nres ua haujlwm kom raug, lossis ua tsis tiav. Kev kho hauv qhov no yog qhov nyuaj heev, vim tias thawj zaug, koj yuav tsum muaj cov txuj ci tsim nyog, thiab qhov thib ob, koj yuav tsum paub dab tsi thiab qhov twg yuav tsum tau solder, thiab nws tsis yog ib txwm muaj peev xwm nrhiav tau tus capacitor txoj cai.
• Tiv tauj oxidation. Qhov no tshwm sim rau tej yam ntuj tso, feem ntau dhau sij hawm. Oxidation tuaj yeem tshwm sim vim qhov tseeb tias thaum txhim kho lub sensor, cov roj tiv thaiv tsis tau siv rau nws cov kev sib cuag, lossis vim muaj kev puas tsuaj rau cov rwb thaiv tsev, cov dej noo tseem ceeb tau txais ntawm cov neeg sib cuag. Thaum kho, nws yog ib qho tsim nyog tsis yog tsuas yog ntxuav cov kev sib cuag los ntawm cov kab mob ntawm corrosion, tab sis kuj yuav tsum lubricate lawv nrog cov roj tiv thaiv yav tom ntej, thiab tseem kom ntseeg tau tias cov dej noo tsis tau txais ntawm cov neeg sib raug zoo yav tom ntej.
• Kev ua txhaum ntawm kev ncaj ncees ntawm cov xaim. Qhov no tuaj yeem tshwm sim vim overheating lossis mechanical puas. Raws li tau hais los saum toj no, lub sensor nws tus kheej, raws li qhov tshwm sim ntawm qhov tseeb tias cov ntsiab lus kis tau zoo heev, kuj ua haujlwm ntawm qhov kub thiab txias. Nyob rau tib lub sij hawm, lub rwb thaiv tsev poob nws elasticity thiab tuaj yeem yooj yim crumble, tshwj xeeb tshaj yog los ntawm cov neeg kho tshuab kev nyuaj siab. Ib yam li ntawd, cov hlua hluav taws xob tuaj yeem raug puas tsuaj nyob rau hauv qhov chaw uas cov xov hlau tawg, lossis vim yog kev tuav tsis zoo. Qhov no feem ntau ua rau lub voj voog luv luv, feem ntau tsis tshua muaj qhov ua tiav ntawm cov xaim, piv txwv li, vim yog kev ua haujlwm ntawm txhua yam khoom siv thiab / lossis kho.
• Chip teeb meem. Feem ntau, cov neeg sib txuas ntawm lub ntsuas hluav taws xob ceev thiab lub tshuab hluav taws xob tswj hluav taws xob yog qhov tsis zoo vim muaj teeb meem nrog lawv kho. uas yog, rau qhov no muaj ib tug thiaj li hu ua "chip", uas yog, ib tug yas retainer uas ua kom ib tug snug haum ntawm rooj plaub thiab, raws li, cov neeg. Feem ntau, lub tshuab latch (lock) yog siv rau kev kho kom nruj.
• Coj los ntawm lwm cov xov hlau. Interestingly, lwm lub tshuab kuj tuaj yeem ua rau muaj teeb meem hauv kev khiav hauj lwm ntawm qhov ceev sensor. Piv txwv li, yog tias cov rwb thaiv tsev ntawm cov xov hlau ntawm lwm tus nyob hauv txoj kev loj nyob ze rau ntawm cov xov hlau ntawm qhov ceev sensor puas lawm. Ib qho piv txwv yog Toyota Camry. Muaj cov xwm txheej thaum lub rwb thaiv tsev ntawm cov xov hlau raug puas tsuaj hauv qhov system ntawm nws qhov chaw nres tsheb sensors, uas ua rau muaj kev cuam tshuam ntawm electromagnetic teb ntawm cov xov hlau ntawm lub sensor ceev. Qhov no ib txwm coj mus rau qhov tseeb tias cov ntaub ntawv tsis raug raug xa los ntawm nws mus rau chav tswj hluav taws xob.
• Hlau shavings ntawm lub sensor. Ntawm cov sensors ceev uas siv cov hlau nplaum tas mus li, qee zaum vim li cas rau nws txoj haujlwm tsis raug yog vim qhov tseeb tias cov hlau nplaum lo rau nws cov khoom rhiab heev. Qhov no ua rau lub fact tias cov ntaub ntawv hais txog lub supposedly xoom ceev ntawm lub tsheb yog kis mus rau lub electronics tswj unit. Lawm, qhov no ua rau kev ua haujlwm tsis raug ntawm lub computer tag nrho thiab cov teeb meem tau piav qhia saum toj no. Yuav kom tshem tau ntawm qhov teeb meem no, koj yuav tsum tau ntxuav lub sensor, thiab nws yog advisable mus dismantle nws ua ntej.
• Sab hauv ntawm lub sensor yog qias neeg. Yog hais tias lub tsev nyob ntawm lub sensor yog collapsible (uas yog, lub tsev yog fastened nrog ob los yog peb bolts), ces muaj xwm txheej thaum av (zoo khib nyiab, plua plav) nkag mus rau hauv lub sensor vaj tse. Ib qho piv txwv yog Toyota RAV4. Txhawm rau txhim kho qhov teeb meem, koj tsuas yog yuav tsum tau disassemble lub sensor vaj tsev (nws yog qhov zoo dua rau pre-lubricate lub bolts nrog WD-40), thiab tom qab ntawd tshem tag nrho cov khib nyiab ntawm lub sensor. Raws li kev xyaum qhia, nyob rau hauv txoj kev no nws muaj peev xwm rov qab ua hauj lwm ntawm ib tug seemingly "tuag" sensor.

Thov nco ntsoov tias rau qee lub tsheb lub ntsuas ntsuas thiab / lossis odometer yuav tsis ua haujlwm raug lossis tsis ua haujlwm vim qhov tsis ua haujlwm ntawm lub ntsuas ntsuas, tab sis vim tias lub dashboard nws tus kheej tsis ua haujlwm raug. Feem ntau, tib lub sijhawm, lwm yam khoom siv nyob ntawm nws kuj "buggy". Piv txwv li, cov ntsuas hluav taws xob hauv hluav taws xob tuaj yeem nres ua haujlwm kom raug vim qhov tseeb tias dej thiab / lossis av tau nkag mus rau hauv lawv cov terminals, lossis muaj qhov tawg ntawm cov teeb liab (lub zog) cov xov hlau. Txhawm rau tshem tawm cov kev sib raug zoo, nws yog feem ntau txaus los ntxuav cov hluav taws xob tiv tauj ntawm lub ntsuas ntsuas.

Lwm qhov kev xaiv yog tias lub cev muaj zog uas tsav lub koob ntsuas lub ntsuas ntsuas tsis raug lossis lub xub tau teeb tsa tob dhau, uas ua rau muaj qhov xwm txheej uas lub koob ntsuas ntsuas nrawm tsuas yog kov lub vaj huam sib luag thiab, raws li, tsis tuaj yeem txav mus rau hauv nws qhov kev ua haujlwm ib txwm muaj. Qee lub sij hawm, vim qhov tseeb tias lub tshuab hluav taws xob sab hauv tsis tuaj yeem txav tau lub xub daig thiab ua rau muaj kev siv zog loj, lub fuse yuav tshuab. Yog li ntawd, nws yog tsim nyog los xyuas nws cov kev ncaj ncees nrog ib tug multimeter. Txhawm rau kom paub tias lub fuse twg yog lub luag haujlwm rau lub ntsuas ntsuas nrawm (ICE xub), koj yuav tsum paub koj tus kheej nrog daim duab thaiv ntawm ib lub tsheb tshwj xeeb.

Yuav ua li cas txheeb xyuas qhov tawg ceev sensor

Cov sensors ceev tshaj plaws tau teeb tsa rau cov tsheb niaj hnub ua haujlwm raws li lub cev Hall nyhuv. Yog li, koj tuaj yeem tshawb xyuas hom kev ntsuas ceev no hauv peb txoj hauv kev, ob qho tib si nrog thiab tsis muaj nws qhov dismantling. Txawm li cas los xij, raws li nws yuav, koj yuav xav tau ib qho hluav taws xob multimeter uas tuaj yeem ntsuas DC voltage txog 12 volts.

Thawj qhov uas yuav tsum tau ua yog xyuas qhov kev ncaj ncees ntawm lub fuse los ntawm kev siv lub zog sensor. Txhua lub tsheb muaj nws tus kheej hluav taws xob Circuit Court, txawm li cas los xij, ntawm VAZ-2114 hais txog lub tsheb, qhov ntsuas ceev ceev tau siv los ntawm 7,5 Amp fuse. Lub fuse yog nyob rau ntawm lub tshuab cua sov relay. Ntawm cov cuab yeej cuab tam hauv lub dashboard pem hauv ntej, cov zis ntsaws nrog qhov chaw nyob - "DS" thiab "controller DVSm" muaj ib tus lej - "9". Siv lub multimeter, koj yuav tsum xyuas kom meej tias lub fuse tsis zoo, thiab cov khoom siv tam sim no dhau los ntawm nws tshwj xeeb rau lub sensor. Yog tias lub fuse tawg lawm, nws yuav tsum tau hloov nrog ib qho tshiab.

Yog tias koj dismantle lub sensor los ntawm lub tsheb, ces koj yuav tsum nrhiav kom paub qhov twg nws muaj ib tug mem tes (cim qhia) hu. Ib qho ntawm cov kev sojntsuam multimeter tau muab tso rau ntawm nws, thiab qhov thib ob yog muab tso rau hauv av. Yog hais tias lub sensor yog kev sib cuag, ces koj yuav tsum tig nws axis. Yog hais tias nws yog magnetic, ces koj yuav tsum tau txav ib yam khoom hlau nyob ze nws lub ntsiab rhiab heev. Qhov nrawm dua qhov txav (kev sib hloov) yog, qhov voltage ntau dua qhov multimeter yuav qhia, yog tias lub sensor ua haujlwm. Yog hais tias qhov no tsis tshwm sim, ces tus ceev sensor yog tawm ntawm kev txiav txim.

Ib txoj kev zoo sib xws tuaj yeem ua nrog lub sensor yam tsis muaj dismantling ntawm nws lub rooj. Lub multimeter nyob rau hauv cov ntaub ntawv no yog txuas nrog tib txoj kev. Txawm li cas los xij, ib lub log pem hauv ntej (feem ntau yog sab xis sab xis) yuav tsum tau jacked mus ua qhov kev xeem. Teem lub iav nruab nrab thiab yuam lub log kom tig thaum tib lub sijhawm saib cov ntawv nyeem ntawm lub tshuab hluav taws xob (nws tsis yooj yim los ua qhov no ib leeg, raws li tus neeg pabcuam yuav tsum tau ua daim tshev hauv qhov no). Yog hais tias lub multimeter qhia tau hais tias ib tug hloov voltage thaum lub log yog tig, ces tus ceev sensor ua hauj lwm. Yog tias tsis yog, lub sensor puas lawm thiab yuav tsum tau hloov.

Nyob rau hauv cov txheej txheem nrog lub log dai tawm, es tsis txhob ntawm multimeter, koj tuaj yeem siv 12-volt tswj lub teeb. Nws zoo sib xws nrog cov teeb liab xaim thiab hauv av. Yog hais tias thaum lub sij hawm tig ntawm lub log lub teeb tig rau (txawm tias sim teeb) - lub sensor nyob rau hauv kev ua haujlwm. Txwv tsis pub, nws yuav tsum tau hloov nrog ib qho tshiab.

Yog tias lub npe ntawm lub tsheb koom nrog kev siv software tshwj xeeb rau kev kuaj xyuas lub sensor (thiab nws lwm yam), ces nws yog qhov zoo dua los siv cov software tsim nyog.

Cov ncauj lus kom ntxaws txog kev ceev sensor tuaj yeem kuaj xyuas siv hluav taws xob oscilloscope. Hauv qhov no, koj tuaj yeem tsis tsuas yog xyuas qhov muaj lub teeb liab ntawm nws, tab sis kuj saib nws cov duab. Lub oscilloscope txuas nrog lub impulse xaim nrog lub log ntawm lub tsheb dai tawm (lub sensor tsis dismantled, uas yog, nws tseem nyob rau hauv nws lub rooj). Tom qab ntawd lub log tig thiab lub sensor tau saib xyuas hauv cov dynamics.

Nws yog ib qho tsim nyog yuav tsum mus dhau tag nrho cov kev xaiv hauv khub. Yog tias cov hlau tawg, ces yuav tsis muaj kev sib cuag rau nws li. Nyob rau hauv cov xwm txheej uas muaj kev puas tsuaj me ntsis rau cov rwb thaiv tsev, nws raug tso cai siv cov ntaub ntawv kub-resistant insulating daim kab xev kom tshem tawm qhov tawg. Txawm li cas los xij, nws tseem zoo dua los hloov cov xaim puas (lossis tag nrho cov pob), vim tias feem ntau cov xov hlau ua haujlwm hauv qhov kub thiab txias, yog li muaj kev pheej hmoo ntawm kev puas tsuaj ntau zaus. Yog tias cov hlau tawg tag, ces, ntawm chav kawm, nws yuav tsum tau hloov nrog ib qho tshiab (lossis tag nrho cov hlua).

Kho qhov sensor

Qee tus kws kho tsheb pib nrog kev kho hluav taws xob kho hluav taws xob tau koom nrog kev kho tus kheej ntawm qhov ceev sensor. uas yog, nyob rau hauv cov ntaub ntawv uas tau piav saum toj no, thaum lub capacitor yog soldered nyob rau hauv lub siab kub, thiab nws pib luv luv thiab dhau tam sim no.

Xws li cov txheej txheem muaj nyob rau hauv disassembling rooj plaub ntawm ceev sensor los xyuas qhov kev ua tau zoo ntawm lub capacitor, thiab yog tias tsim nyog, hloov nws. Feem ntau, microcircuits muaj Japanese lossis Suav capacitors, uas tuaj yeem hloov pauv nrog cov khoom siv hauv tsev. Qhov tseem ceeb tshaj plaws yog xaiv qhov tsim nyog tsis - qhov chaw ntawm kev sib cuag, nrog rau nws lub peev xwm. Yog hais tias lub sensor vaj tse yog collapsible - txhua yam yog yooj yim, koj tsuas yog yuav tsum tau tshem tawm lub hau thiaj li mus rau lub condenser. Yog tias rooj plaub tsis sib cais, koj yuav tsum ua tib zoo txiav nws yam tsis muaj kev puas tsuaj rau cov khoom sab hauv. Ntxiv rau qhov yuav tsum tau teev saum toj no rau kev xaiv lub capacitor, koj kuj yuav tsum tau them sai sai rau nws qhov loj, txij li tom qab soldering rau lub rooj tsavxwm, lub sensor vaj tse yuav tsum kaw dua tsis muaj teeb meem. Koj tuaj yeem ua kua nplaum rau rooj plaub nrog cov kua nplaum kub-resistant.

Raws li kev txheeb xyuas ntawm cov tswv uas ua haujlwm zoo li no, koj tuaj yeem txuag tau ntau txhiab rubles li no, txij li lub sensor tshiab yog kim heev.

xaus

Lub sensor tsis ua haujlwm nrawm yog qhov tsis tseem ceeb, tab sis qhov teeb meem tsis zoo. Tseeb tiag, tsis yog tsuas yog kev nyeem ntawv ntawm lub ntsuas ntsuas thiab ntsuas ntsuas ntsuas nyob ntawm nws qhov kev ua haujlwm ib txwm muaj, tab sis kuj tseem siv roj ntau ntxiv, thiab lub tshuab hluav taws xob sab hauv tsis ua haujlwm tag nrho. Tsis tas li ntawd, cov tsheb sib cais raug yuam kom kaw, uas tuaj yeem cuam tshuam, ntawm lwm yam, kev nyab xeeb kev tsheb, ob qho tib si hauv nroog hom thiab ntawm txoj kev loj. Yog li ntawd, thaum txheeb xyuas cov teeb meem nrog lub sensor ceev, nws yog ib qho tsim nyog kom tsis txhob ncua lawv tshem tawm.
