Hanyoyi don bincika firikwensin ABS

Na'urori masu auna firikwensin ABS suna taka muhimmiyar rawa wajen aiwatar da tsarin birki na abin hawa - ingantaccen aikin birki da santsin aikin naúrar gaba ɗaya ya dogara da su. Abubuwan firikwensin suna watsa bayanai akan matakin jujjuyawar ƙafafun zuwa naúrar sarrafawa, kuma sashin kulawa yana nazarin bayanan mai shigowa, gina algorithm na ayyuka da ake so. Amma menene za a yi idan akwai shakku game da lafiyar na'urorin?

Alamomin na'urar rashin aiki

Gaskiyar cewa na'urar firikwensin ABS ba ta da kyau yana nuna alamar ta hanyar mai nuna alama a kan kayan aikin: yana haskakawa lokacin da aka kashe tsarin, yana fita har ma da ƙananan rashin aiki.

Shaida cewa ABS ta daina "tsangwama" tare da birki:

• Ƙafafun suna kulle kullun a ƙarƙashin birki mai nauyi.
• Babu siffa ƙwanƙwasawa tare da jijjiga lokaci guda lokacin danna fedalin birki.
• Alurar gudun mita tana bayan hanzari ko kuma baya motsawa kwata-kwata daga matsayinta na asali.
• Idan biyu (ko fiye) na'urori masu auna firikwensin akan faifan kayan aiki sun gaza, alamar birki ta ajiye motoci tana haskakawa kuma baya fita.

Alamar ABS akan dashboard tana nuna rashin aiki na tsarin

Menene zan yi idan alamar ABS akan dashboard ɗin motar ba ta yi daidai ba? Kada ku canza firikwensin nan da nan, kuna buƙatar fara duba na'urorin; Ana iya aiwatar da wannan hanya da kanta, ba tare da yin amfani da sabis na masters masu biyan kuɗi ba.

Hanyoyin duba lafiya

Don tantance yanayin ɓangaren, muna yin jerin ayyuka don tantance shi, daga sauƙi zuwa hadaddun:

1. Bari mu bincika fuses ta buɗe toshe (a cikin rukunin fasinja ko a cikin injin injin) da bincika abubuwan da suka dace (an nuna a cikin littafin gyara / aiki). Idan an sami wani abu da ya kone, za mu maye gurbinsa da wani sabo.
2. Mu duba mu duba:
   • amincin haɗin haɗin;
   • wiring don abrasions wanda ke ƙara haɗarin ɗan gajeren kewaye;
   • gurɓataccen sassa, yiwuwar lalacewar inji na waje;
   • gyarawa da haɗi zuwa ƙasa na firikwensin kanta.

Idan matakan da ke sama ba su taimaka wajen gano rashin aiki na na'ura ba, dole ne a duba ta da na'urori - mai gwadawa (multimeter) ko oscilloscope.

Gwaji (multimeter)

Don wannan hanyar gano firikwensin, kuna buƙatar mai gwadawa (multimeter), umarnin don aiki da gyara motar, da kuma PIN - wiring tare da masu haɗawa na musamman.

Na'urar tana haɗa ayyukan ohmmeter, ammeter da voltmeter

Gwaji (multimeter) - na'ura don auna ma'aunin lantarki, haɗa ayyukan voltmeter, ammeter da ohmmeter. Akwai samfuran analog da dijital na na'urori.

Don samun cikakken bayani game da aikin firikwensin ABS, dole ne a auna juriya a cikin da'irar na'urar:

1. Tada motar tare da jack ko rataye ta akan ɗagawa.
2. Cire dabaran idan ya hana shiga na'urar.
3. Cire murfin akwatin sarrafa tsarin kuma cire haɗin haɗin haɗin daga mai sarrafawa.
4. Muna haɗa PIN ɗin zuwa multimeter da lambar firikwensin firikwensin (masu haɗin firikwensin baya suna cikin rukunin fasinja, ƙarƙashin kujeru).

Muna haɗa PIN zuwa mai gwadawa da lambar firikwensin

Dole ne karatun na'urar ya dace da bayanan da aka kayyade a cikin littafin don gyara da aiki na wani abin hawa. Idan juriya na na'urar:

• a ƙasa mafi ƙarancin madaidaicin - firikwensin yana da kuskure;
• hanyoyin sifili - gajeren kewaye;
• m (tsalle) a lokacin ƙarfafa wayoyi - cin zarafi na lamba a cikin na'urar;
• mara iyaka ko babu karatu - kebul break.

Hankali! Juriya na na'urori masu auna firikwensin ABS na gaba da na baya sun bambanta. Siffofin aiki na na'urorin sun kasance daga 1 zuwa 1,3 kOhm a cikin akwati na farko kuma daga 1,8 zuwa 2,3 kOhm a cikin na biyu.

Bidiyo "ABS Sensor Diagnostics"

Yadda ake dubawa da oscilloscope (tare da zane mai wayoyi)

Bugu da ƙari, bincikar kai na firikwensin tare da mai gwadawa (multimeter), ana iya bincika shi tare da na'urar da ta fi rikitarwa - oscilloscope.

Na'urar tana bincika girman girman da sigogin lokacin siginar firikwensin

Oscilloscope na'ura ce da ke nazarin girma da sigogin lokaci na sigina, wanda aka ƙera don tantance daidaitattun hanyoyin bugun jini a cikin da'irori na lantarki. Wannan na'urar tana gano munanan masu haɗawa, kurakuran ƙasa da karyawar waya. Ana yin rajistan ne ta hanyar kallon gani na girgizar da ke kan allon na'urar.

Don tantance firikwensin ABS tare da oscilloscope, dole ne ku:

1. Yi cajin baturi cikakke don lura da raguwar ƙarfin lantarki (spikes) akan masu haɗawa ko jagora yayin aunawa.
2. Nemo firikwensin taɓawa kuma cire haɗin babban haɗin kai daga ɓangaren.
3. Haɗa oscilloscope zuwa tashar wuta.

Haɗa na'urar zuwa mai haɗin firikwensin ABS (1 - diski-rotor mai haƙori; 2 - firikwensin)

Matsayin firikwensin ABS yana nuna ta:

• girman girman siginar sigina yayin jujjuyawar ƙafafun gatari ɗaya;
• rashin girman bugun jini lokacin da aka gano tare da siginar sinusoidal na ƙananan mitar;
• rike da tsayin daka da daidaito na jujjuyawar siginar, baya wuce 0,5 V, lokacin da dabaran ke juyawa a mitar 2 rpm.

Lura cewa oscilloscope na'ura ce mai rikitarwa da tsada. Fasahar kwamfuta ta zamani ta ba da damar maye gurbin wannan na'urar tare da wani shiri na musamman da aka zazzage daga Intanet kuma aka sanya shi a kwamfutar tafi-da-gidanka na yau da kullun.

Duba wani sashi ba tare da kayan aiki ba

Hanya mafi sauƙi don gano na'urar maras hardware ita ce bincika bawul ɗin solenoid akan firikwensin shigar. Ana amfani da duk wani samfurin ƙarfe (screwdriver, wrench) zuwa ɓangaren da aka shigar da maganadisu. Idan firikwensin bai jawo shi ba, yana da lahani.

Yawancin na'urorin hana kulle birki na motoci na zamani suna da aikin tantance kansu tare da fitowar kuskure (a cikin lambobin haruffa) akan allon kwamfutar kan allo. Kuna iya tantance waɗannan alamomin ta amfani da Intanet ko littafin koyarwa na inji.

Abin da za a yi idan an gano lalacewa

Me za a yi da firikwensin ABS idan an sami matsala? Idan matsalar ita ce na'urar kanta, to dole ne a canza ta, amma a yanayin sadarwar lantarki, zaka iya gyara matsalar da kanka. Don mayar da mutuncinsa, muna amfani da hanyar "welding", a hankali kunsa haɗin gwiwa tare da tef ɗin lantarki.

Idan hasken ABS ya zo a kan dashboard, wannan alama ce bayyananne na matsalar firikwensin. Ayyukan da aka bayyana za su taimaka wajen gano dalilin lalacewa; duk da haka, idan ilimi da kwarewa ba su isa ba, yana da kyau a tuntuɓi ma'aikatan sabis na mota. In ba haka ba, bincikar rashin iya karatu na yanayin, haɗe tare da gyara na'urar ba daidai ba, zai rage tasirin tsarin hana kulle birki kuma yana iya haifar da haɗari.
