Uantej wiper tsis ua hauj lwm: yuav tau ua thiab daws tau qhov teeb meem

Tawg uantej wipers tsis tsuas txaav rau tus neeg tsav tsheb thaum tsav tsheb nyob rau hauv lub nag los yog daus, tab sis kuj yuav ua rau ib tug tsheb huam yuaj. Pom zoo ib yam li kev puas tsuaj nyob rau hauv huab cua, nws yog ib qhov zoo dua tsis mus, thiab coj kho kev txiav txim.

Nyob rau hauv no tsab xov xwm uas peb yuav tham txog yog vim li cas tsis ua hauj lwm wiper, thiab xav txog txoj kev mus rau qhov lawv nyob rau hauv lub tsheb piv txwv li, Vaz-2114.

Tus tsim ntawm lub windscreen wiper

Wiper tuaj los ntawm "Kaum plaub" yog tsav los ntawm ib tug mechanism uas muaj:

• lub cev muaj zog;
• tswj tsev;
• hluav taws xob kev tiv thaiv cov ntsiab;
• Drive (Trapezoid);
• leashes nrog txhuam.

engine

Lub zog ntawm tus janitors yog muab los ntawm ib tug hluav taws xob motor, nyob rau hauv lub hood nyob ze ntawm lub muab faib nkauj nraug lub engine compartment thiab alarm. Nws muaj ib tug built-in yuav txo tau iav thiab yog txawm peem rau nrog peb txhuam. Lawv cia koj mus kho cov kev ceev ntawm lub zog ntawm tus txhuam rau ntawm iav.

tswj thaiv

lag luam ntawm lub janitors tswj chav tsev yog nyob rau hauv lub kauj kem mus rau sab xis. Nws lub luag hauj lwm yog kom muaj ib tug wiper mus thiab nws cov high-speed hom.

Wiper tswj tsev muaj 4 txoj haujlwm:

• thawj (qis tshaj) - lub mechanism yog muab tua;
• lub thib ob - tus wipers khiav lag luam intermittently;
• peb - txhuam tsiv sai sai;
• plaub - wipers tsiv sai li sai tau.

tiv thaiv cov ntsiab

Hluav taws xob cov kev tiv thaiv circuits yog nqa wiper fuse. Nws yog mas cov mounting thaiv thiab yog denoted nyob rau hauv Scheme F-5. Muaj kuj yog ib tug mus hais tias yog lub luag hauj lwm rau lub chaw ua hauj lwm ntawm janitors nyob rau hauv lub sib quas ntus hom. Nyob rau hauv daim duab, nws yog denoted li K-2 los yog K-3.

tsav

Lub quab yuam los ntawm cov lub cev muaj zog rau tus txhuam txoj hlua cab yog kis tau los ntawm txoj kev ntawm ib tug Trapezoid. Nws yog ib tug system ntawm rods thiab levers uas hloov lub torque lub cev muaj zog ntawm ib tug reciprocating suab ntawm lub janitors. Trapeze kuj nyob rau hauv lub kaus mom, tom ntej no mus rau lub cev muaj zog.

Leads & txhuam

Txhua wiper yog muaj li ntawm ib tug ua thiab txhuam. Lawv sib thooj, los ntawm txoj kev ntawm ib tug tshwj xeeb Symptoms. Txoj hlua cab zog ua tus muaj nuj nqi, dua tus txhuam quab yuam los ntawm cov crank Trapezoid. Mus rau crank ncej nws yog txuas los ntawm txoj kev splines thiab lub clamping noob txiv.

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub mechanism

Yuav nrhiav tau cov yog vim li cas rau tsis ua hauj lwm wiper, koj yuav tsum to taub yuav ua li cas nws ua hauj lwm nws cov mechanism. Thiab nws ua hauj lwm raws li nram no. Thaum peb tsiv mus nyob rau kov ntawm cov kev tswj chav tsev lub wiper mus rau tus thawj txoj hauj lwm, voltage yog thov mus rau lub cev muaj zog ntawm ib lub relay. Tsaug rau nws, tus wipers txav intermittently, piv txwv li. E. Nrog khoob ntawm strokes. Thaum lub ceev ceev hom, lawv tsiv mus nyob nrog tsawg ntev pauses. Txav mus rau tus kov rau nws siab tshaj plaws txoj hauj lwm ua rau lub wipers yuav tawm mus sai li sai tau (tsis muaj sij hawm).

Yog vim li cas tsis yog qhov uantej wipers

Ntawm cov feem ntau teeb meem txuam nrog rau lub lag luam ntawm daim iav tu mechanism yuav tsum tau qhia:

• cua tshuab fuse;
• tawg nyob rau hauv qhov hluav taws xob Circuit Court (oxidation ntawm cov neeg, disconnection ntawm connectors, xov disconnection);
• tsis ua hauj lwm ntawm lub relay;
• txhaum hloov tswj tsev;
• txhuam coj los kaw (qhib) nyob rau hauv lub windings ntawm lub cev muaj zog;
• jamming lub Actuator caj npab (Trapezoid);
• splines hnav leashes.

fuse

Noticing hais tias cov wipers nres ua hauj lwm, ua ntej khij lub fuse. Nws yog nws leej twg yog feem ntau qhov ua rau ntawm tus txhaum. Nws yog soj ntsuam los ntawm "proring" tester. Cua tshuab kev tiv thaiv lub caij, tsuas yog hloov, thiab ces mus saib lub lag luam ntawm lub mechanism.

qhib circuit Court

Yog hais tias tom qab hloov cov fuse, tsis tsis khiav lub wiper hniav, tej zaum yuav muaj teeb meem nrog rau cov xov. Xyuas seb connectors yog tawg:

• tswj tsev;
• relay;
• lub cev muaj zog.

Nyob rau hauv cov ntaub ntawv ntawm kev nrhiav kom tau nyob rau ntawm qhov terminals ntawm lub connectors oxidation, lawv smooth tawm zoo Emery daim ntaub thiab kho cov kua thaiv tus kab xeb (xws li WD-40).

faulty relays

Lwm yog vim li cas vim li cas lub wiper tsis ua hauj lwm, tej zaum nws yuav tsum yog ib tug relay. Ua ntej ntawm tag nrho cov, tshem tawm nws los ntawm lub rooj zaum nyob rau hauv lub rooj sib txoos thaiv thiab muab tso rau nws rov qab. Feem ntau, cov teeb meem lus dag nyob rau hauv lub banal hu oxidation. Yog hais tias qhov no tsis ua hauj lwm, cia nws nyob rau hauv lub rooj sib txoos thaiv thiab mus rau lub salon.

wiper mus yog tsuas lub luag hauj lwm rau nws ua hauj lwm nyob rau hauv discontinuous hom, yog li ntawd, nyob rau hauv ib tug ceev ceev thiab ceev heev hom, nws tsis koom nrog. Xa rau lub ignition mus thiab txhais cwj mem wiper hom nyob rau hauv uppermost txoj hauj lwm. Janitors khwv tau? Hloov cov relay. Los ntawm txoj kev nws catalog tooj rau lub "xab kaum plaub" 52,3747 los yog 525,3747, thiab nws nqi txog 150 rubles. Ib me ntsis kim kim (txog 250 rubles) yuav raug nqi ib qho adjustable wiper hloov uas tso cai rau yuav tau kho qhov ntev ntawm lub mas ntawm lawv tus cwj nrag.

ncua sij hawm hloov yuav siv sij hawm qhov chaw los ntawm translation hom switching pob qhov rooj ntawm txoj hauj lwm "On". nyob rau hauv lub thib ob txoj hauj lwm, uas tus wipers khiav lag luam intermittently. Nyob rau tib lub sij hawm uas lawv pib tsiv mus nyob rau ib qho hom, ib tug shutter ceev kwv yees li 4 lub vib nas this. Ntxiv mus, cov kev tswj yog tsiv mus rau cov hauj lwm "tawm." Thiab pib lub countdown rau lub programmed mas. Lub sij hawm tom qab koj tig mus rau ntawm wipers nyob rau hauv sib quas ntus hom koj yuav tau hwm pab kis.

Lub txhaum tswj tsev

Ib tug malfunction ntawm lub tswj chav tsev yog tsis muaj cov tshuaj tiv thaiv wiper mechanism ntawm lub npe hu fuse, lub cev muaj zog thiab rau tag nrho cov xov.

Feem ntau nws tsis tsis yog vim cov neeg kho tshuab tsis ua hauj lwm, tab sis vim hais tias ntawm cov oxidation uas cov neeg. Yuav kom ntes tau ua muaj rau lauj lub tsev, soj ntsuam thiab, los ntxuav lub hu hais thaum tsim nyog.

Yog hais tias qhov no tsis, lub chav tsev yuav tsum tau hloov.

Teeb meem nrog lub cev muaj zog

Kos thaiv thiab Circuit Court kev tiv thaiv cov ntsiab ntawm cov wiper, thiab tsis nrhiav kev txhaum kev tshawb nrhiav electric tsav tsav tsheb nws mechanism. Ua li no, muab rho lub cav zoo dua.

Nyob rau hauv ua li ntawd, hloov rau ntawm cov ignition thiab tsiv mus nyob rau chaw ua hauj lwm ntawm cov kev tswj chav tsev hloov pob qhov rooj wipers yoo mov los yog ceev heev hom. Siv ib tug multimeter tshev yuav tsum nyuaj siab nyob rau hauv lub cev muaj zog connector. Tus ntaus ntawv yuav tsum qhia tias tus tib voltage li lub roj teeb. Puas tias tam sim no nce mus txog lub electric tsav, thiab nyob rau hauv ua li ntawd nws tsis khiav, nws muaj peev xwm yuav xaus lus tias tus wiper tsis ua hauj lwm precisely vim hais tias ntawm engine teeb meem.

Qhov no tshwm sim feem ntau vim hnav ntawm qhov tam sim no mov ntawm txhuam, tab sis tej zaum qhov teeb meem lus dag nyob rau hauv lub kaw ntawm lem ntawm ib yam ntawm cov windings. Cov hluav taws xob lub cev muaj zog muaj peev xwm sim kho los ntawm hloov lub txhuam, los yog es ua kom cov winding, tab sis nws yooj yim mus yuav tau ib lub tshiab. Nws yog ib nqi nws nyob rau hauv ib txhiab rubles.

Malfunction ntawm lub Trapezoid thiab leashes

Los ntawm nws tus kheej, lub trapeze tsis heev tsis tshua muaj, vim hais tias nyob rau hauv thiaj li yuav ua txhaum nws, yuav yuav tsum tau txiav txim siab siv zog. Nyob rau hauv feem ntau tus neeg mob, muaj teeb meem nrog nws tom qab lub kho los yog kev hloov ntawm lub tsav levers.

Tab sis raws li leashes, ces lawv tawg feem ntau. Lub ntsiab qhov teeb meem - lub coj ntawm lub splines. Lub fact tias lawv yog ua los ntawm txhuas, yog li ntawd txawm ib tug me me quab yuam thov nyob rau hauv cov kev taw qhia opposite rau lub zog ntawm tus wipers yuav hu lawv "slizyvanie". Nyob rau hauv xws li ib tug teeb meem no yog ib txoj kev tawm - cov kev hloov.

Tsheb wiper tsis ua hauj lwm

Vaz-2114 yog txawm peem rau nrog ib tug rear qhov rais wiper. Tu siab, nws tej zaum tsis. Qhov zoo ces, muaj cov tsis muaj fuses los yog relays. rear wiper mechanism muaj ib tug hluav taws xob motor nrog iav thiab txoj hlua cab nrog ib tug txhuam. Nws xam yog ua los ntawm switching los ntawm qhov kov nws tus kheej (kab rov tav).

Mob ntawm lub rear wiper yog ua kuj ntawm xab lub voltage thoob plaws lub cev muaj zog connector. Yog hais tias nws yog hos, yuav yog kho los yog yuav ib tug tshiab lub cev muaj zog.
