Kawirikawiri, pakachitika kachipangizo kapena kulephera kwathunthu kwa sensa, kukonza kwake sikungatheke, popeza thupi lake limasindikizidwa komanso losagawanika. Chifukwa chake, ndizosatheka kuti m'malo mwa waya (kumulowetsa) ndi / kapena pachimake pa maginito. Pachifukwa ichi, sensa yosagwiritsidwa ntchito imachotsedwa, ndipo yatsopano imagulidwa ndikuyika m'malo mwake, popeza mtengo wake ndi wotsika, ndipo malo ogulitsira amapereka mitundu yosiyanasiyana yamagalimoto osiyanasiyana.

Momwe mungadziwire sensor yosweka ya crankshaft

Pali njira yosavuta yodziwira ngati sensa yathyoka ndipo aliyense angathe kuchita ndi multimeter imodzi. Pamagalimoto ambiri amakono, ndi ma induction crankshaft position sensors omwe amaikidwa, kotero tikhala mwachidule pazowunikira zida zamtunduwu.

Choncho, DPKV akhoza kufufuzidwa m'njira zitatu - ohmmeter, kuona kufunika kwa inductance wa koyilo, komanso ntchito oscilloscope. Kuphatikiza apo, chinthu chofunikira pakuwunika kuti ndi ziti zomwe zikuwonetsa kuwonongeka kwa sensa ya crankshaft ndikukhazikitsa kusiyana koyenera pakati pa chinthu chovuta cha sensor, komanso disk synchronization (mtunda uyenera kufotokozedwa muzolemba, zili mkati. kutalika kwa 0,5 ... 1,5 mm).

Momwe mungayang'anire sensor ya crankshaft?

Есть три способа проверки ДПКВ – мультиметром (проверяется сопротивление обмотки), тестером (проверяется сопротивления изоляции и индуктивности) и осциллографом. Подробнее

 

Njira yosavuta komanso yofikirika kwambiri kwa pafupifupi mwini galimoto iliyonse ndiyowona kukana kwamkati kwa sensa. Kuti muchite izi, ndikwanira kugwiritsa ntchito multimeter yamagetsi yosinthidwa kukhala njira yoyezera kukana kwa dera lamagetsi. Kwa masensa ambiri amakono, mtengo wa kukana kwamagetsi kwa koyilo yamkati ndi pafupifupi 500 ... 700 Ohm (nthawi zina, mtengo uwu ukhoza kusiyana, choncho ndi bwino kudziwiratu ndi magawo aukadaulo a sensa padera). m'pofunikanso kuyang'ana mtengo wa insulation ya mawaya. Iyenera kukhala yosachepera 0,5 MΩ.

Kuti muyese inductance, mwini galimotoyo adzafunika multimeter (megaohmmeter), transformer network, inductance mita, ndi voltmeter. Kusiya ma aligorivimu otsimikizira, ndikofunikira kuzindikira nthawi yomweyo kuti mtengo wa inductance wa koyilo yamkati ya sensa yogwira ntchito uyenera kukhala pafupifupi 200 ... 400 mH (zitha kukhala zosiyana ndi masensa osiyanasiyana, koma pang'ono). Ngati inductance ndi yotsika kwambiri (kawirikawiri yokwera), ndiye kuti sensa ndiyotheka kwambiri, ndipo kufufuza kwina kuyenera kuchitidwa, kuphatikizapo kuyeza kukana kwa koyilo ndi kutsekemera.

Njira yovuta kwambiri, koma yothandiza kwambiri komanso yodalirika yowonera sensa ya crankshaft ili ndi oscilloscope, nthawi zambiri zamagetsi (mapulogalamu emulator). Kuti muchite izi, oscilloscope imalumikizidwa ndi zotuluka za sensa ndi injini yoyaka mkati mwagalimoto yomwe ikuyenda ndipo pulogalamuyo imakhazikitsidwa kuti itenge oscillogram. Chojambula chake chidzapereka kumvetsetsa bwino ngati sensor ikugwira ntchito, komanso ngati pali mipata iliyonse panthawi yomwe ikugwira ntchito. Kuphatikiza apo, mutha kutulutsa sensa kuchokera pampando wake, kulumikiza oscilloscope ndi kungosuntha chinthu chachitsulo pafupi ndi chinthu chake chovuta (mwachitsanzo, screwdriver). Ngati imazindikira kusuntha, ndipo oscillogram imapangidwa pazenera, mwina sensa ikugwira ntchito.

Panthawi yotsimikizira, sikungakhale kofunikira kuyang'ana zolakwika kuchokera pamtima pakompyuta pogwiritsa ntchito makina apadera. Izi zidzathandiza onse kudziwa cholakwika cha DPKV ndi zinthu zina za injini kuyaka mkati.

Momwe mungapusitsire sensor ndikuyambitsa galimoto

Pogwiritsa ntchito chitsanzo cha Vaz 2110, ganizirani njira yabwino yoyambira injini pamene sensa ya crankshaft sikugwira ntchito.

Kuti muchite izi, muyenera kupukusa waya wochepa thupi wamkuwa pa sensa thupi, kupanga mtundu wa mafunde. Waya akhoza kutengedwa kuchokera ku relay iliyonse. Kuzungulira thupi, muyenera kupanga ma skein 150, ndikutengera zotsalazo ku chip chomwe chimalumikizana ndi DPKV ndikumatira malekezero mu cholumikizira m'malo mwa sensa ya crankshaft.

Kuzungulira waya wamkuwa kuzungulira thupi la sensa

Kukonza mawaya pa chip

Musanayambe kupotoza waya wamkuwa, mapepala awiri kapena makatoni owonda amatha kupangidwa mozungulira thupi la sensor.

Waya amakulungidwa pamwamba pa pepala, kenako amachotsedwa, kotero kuti mapiringidzo opangidwa kunyumba nthawi zambiri amakwanira pathupi.

Ngati injini yoyaka mkati siyamba, ndiye kuti padzakhala kofunikira kusinthana ndi waya wolumikizidwa ndi kulumikizana kwa chip. kuti mawayawa asagwe, akhazikitsidwe kwakanthawi ndi machesi. Simuyenera kukwera ndi mapangidwe otere kwa nthawi yayitali, pambuyo pake, DPKV yolephera iyenera kusinthidwa!

Ntchito yonseyo idzatenga zosaposa mphindi 5 ndi waya mita imodzi.

Chofunikira cha njira yomwe yaperekedwa ndikubwezeretsa pang'ono njira ya electromagnetic induction. Ndiko kuti, pakagwa kuwonongeka kwa koyilo yokhazikika (yodzaza m'nyumba), ndizotheka kupanga koyilo yoyambira yomwe imatha kugwira ntchito limodzi ndi crankshaft centering pulley. Zotsatira zake, chizindikirocho chidzafika ku ECU ndipo injini yoyaka mkati idzayamba. Onani kanema pansipa kuti mudziwe zambiri.
