Momwe mungayang'anire sensor yothamanga - 3 njira zosavuta
Zamkatimu
Liwiro la galimoto liyenera kudziwika osati kungodziwitsa dalaivala. Makina ambiri amagetsi amagwiritsa ntchito liwiro ngati gawo lolowera pakuwongolera koyenera kwa magawo omwe ali pansi. Pali njira zingapo zodziwira mtengowu, nthawi zambiri sensa yosiyana imagwiritsidwa ntchito pakufalitsa.
Cholinga ndi malo a DS
Galimoto yothamanga sensor (DS) imagwira ntchito zingapo zamakina:
- amapereka chizindikiro kwa dashboard kuti adziwitse dalaivala mumtundu wowerengeka wosavuta wa digito kapena muvi;
- lipoti liwiro ku gawo lowongolera injini;
- imapereka mtengo wothamanga ku basi yazidziwitso zonse zagalimoto kuti zigwiritsidwe ntchito ndi makina othandizira oyendetsa.
Mofananamo, chidziwitso cha liwiro chikhoza kutengedwa kuchokera ku masensa othamanga a ABS, deta idzafaniziridwa ndi mayunitsi amagetsi.
DS ili pa imodzi mwazinthu zotumizira, ikhoza kukhala bokosi la gear kapena posamutsa. Nthawi zina kuyendetsa mwachindunji kuchokera kumodzi mwa mawilo kunkagwiritsidwa ntchito.
Mfundo ya ntchito ya liwiro sensa
M'malo mwake, DS imayesa osati liwiro, koma liwiro lozungulira la gawo lomwe lili ndi mphete. Mtengo uwu ukhoza kusinthidwa kukhala liwiro pamakina kapena pakompyuta, popeza kufalitsa kuli ndi ubale wosadziwika komanso wodziwika pakati pa pafupipafupi ndi liwiro ndi kukula kwa gudumu.
Kuyika matayala kapena mawilo a kukula kosiyana kumabweretsa cholakwika pakuyeza liwiro. Komanso kukonzanso kwa kufalitsa ndi kusintha kwa magiya pambuyo pa DS.
Zomverera zimatha kukhala zamakina kapena zamagetsi. Makina a DS sagwiritsidwanso ntchito; m'mbuyomu anali ndi chipangizo chamtundu wa giya chomwe chimakhala ndi chingwe chotchinga. Kuzungulira kwa chingwecho kunatumizidwa ku dashboard, kumene maginito amalumikizana nawo.
Kusinthasintha kwa maginito kunapangitsa mafunde a makoyilo, omwe amayezedwa ndi pointer milliammeter yosinthidwa malinga ndi liwiro.
Mawotchi othamanga omwe amatsatira nthawi zambiri amaphatikizidwa ndi makina a rev counter - odometer yomwe imalemba mtunda wa tsiku ndi tsiku wa galimotoyo.
Masensa amagetsi amatha kugwiritsa ntchito mfundo zosiyanasiyana pantchito yawo:
- kuwala, pamene mtengowo ukudutsa mipata mu diski yozungulira;
- magnetoresistive, maginito ozungulira ma multipole amachititsa kusintha kwa magetsi a chinthu chomva;
- kupatsidwa ulemu, zitsulo mbali cyclically kusintha munda wa maginito okhazikika, zomwe zimayambitsa alternating panopa mu koyilo kuyeza;
- pa Hall effect, malo osinthira maginito amakhazikika ndi kristalo yowoneka bwino ya semiconductor, pambuyo pake shaper imapanga njira yolandirira ma pulse blocks omwe ndi oyenera kugwira ntchito.
Nthawi zambiri muukadaulo wamakono, zida zokhala ndi Hall effect ndi maginito omangika zimagwiritsidwa ntchito, zomwe zimatha "kuwerengera" mano a korona aliyense wachitsulo akudutsa.
Zizindikiro
Ngati DS ikulephera, zamagetsi zidzazindikira izi nthawi yomweyo, nkhaniyi siidzangokhala chabe kusowa kwa zizindikiro pa chida. Cholakwika chidzawonetsedwa ndi kuperekedwa kwa code yofanana, unit idzalowa muzochitika zadzidzidzi, zomwe zidzakhudza ntchitoyo nthawi yomweyo.
Injini imayamba kuyimilira osalowerera ndale ndikuyendetsa, kugwiritsa ntchito kumawonjezeka ndipo mphamvu idzachepa. Chiwongolero champhamvu chamagetsi chomwe chimagwiritsa ntchito chidziwitso cha liwiro chidzalephera. Kompyuta yapaulendo idzasiya kugwira ntchito.
Njira za 3 zowonera sensor yothamanga
Choyamba, ndi bwino kuyang'ana magetsi ndi mawilo a chizindikiro. Apa, ambiri ndi makutidwe ndi okosijeni wa kulankhula, kuphwanya kuthetsa mawaya mu zolumikizira, dzimbiri ndi mawotchi kuwonongeka kwa mawaya. Kenako pitilizani kuyang'ana sensor yokha.
Muyeneranso kulumikiza chipangizo choyezera matenda ku ECU ndikuzindikira zolakwika. Mwachitsanzo, izi zitha kuchitika pogwiritsa ntchito Rokodil ScanX universal autoscanner.
Ngati palibe zolakwika pa sensa yothamanga, ndikofunikira kufananiza kuwerengera kwa liwiro la liwiro ndi sensor mukugwiritsa ntchito ndi scanner mukuyendetsa. Ngati zotsatira zikugwirizana, ndiye kuti sensoryo imakhala mwadongosolo.
Kugwiritsa ntchito tester (multimeter)
Chizindikiro pakutulutsa kwa DS molingana ndi mfundo ya Holo iyenera kusintha ndi kuzungulira kwa zida zoyendetsa za sensor. Ngati mulumikiza multimeter mu voltmeter mode ndikuzungulira giya, mutha kuwona kusintha kwamawerengedwe (chizindikiro cha pulse) pamayendedwe a sensor inayake.
- chotsani sensa m'galimoto;
- gwirizanitsani cholumikizira ndikuyang'ana kukhalapo kwa magetsi abwino ndikukhudzana ndi nthaka;
- gwirizanitsani voltmeter ku waya wa chizindikiro ndikuyendetsa galimoto kuti muwone kusintha kwa kuwerenga.
Zonse zomwezo zitha kufufuzidwa pa cholumikizira cha gulu la zida kapena chowongolera injini, kotero mawayawo adzayang'aniridwa.
popanda kuchotsa wowongolera
Simungathe kuchotsa DS, pobweretsa kuyendetsa kwake mozungulira mwachilengedwe. Kuti muchite izi, mawilo oyendetsa galimoto amapachikidwa, injini imayamba, pambuyo pake pa liwiro lotsika ndizotheka kudziwa kukhalapo kapena kusapezeka kwa chizindikiro malinga ndi kuwerenga kwa voltmeter yolumikizidwa.
Kuyang'ana ndi chowongolera kapena babu
Kutulutsa kwa sensa nthawi zambiri kumakhala dera lotseguka. Ngati mulumikiza chizindikiro chowongolera ndi LED kapena babu yamphamvu yotsika pakati pa mphamvu yowonjezera ndi kukhudzana ndi chizindikiro cha sensa, ndiye mutatha kupota, monga tafotokozera pamwambapa, mukhoza kuyang'ana kuphethira kwa chizindikiro chowongolera.
Momwe mungayang'anire drive DS
Nthawi zambiri, zida zoyendetsera DS zimapangidwa ndi pulasitiki, zomwe zimapangitsa kuti mano awonongeke. Ngati sensa ikumveka bwino, ndiye kuti ndikofunikira kuyang'ana chinkhoswe.
Izi zitha kuwonedwa poyang'ana mano, kapena kupukuta gudumu loyendetsa, kuti muwone kupezeka kwa kuzungulira kwa sensor rotor.
Malangizo obwezeretsa
Kusintha sensa sikovuta; nthawi zambiri imakhazikika m'nyumba ya gearbox yokhala ndi screw ya flange. Mwa kumasula screw iyi ndikuchotsa cholumikizira, sensa imatha kuchotsedwa ndikuyika yatsopano.
Kusindikiza, gasket wokhazikika kapena sealant amagwiritsidwa ntchito. Pambuyo m'malo, ndikofunikira kukonzanso zolakwika zomwe zilipo ndi scanner kapena kuchotsa mwachidule terminal mu batri.
Musanayambe ntchitoyo, ndikofunikira kuyeretsa bwino bokosi la bokosi mozungulira sensor kuti mupewe ma abrasives kulowa mu crankcase. Malo oyandikana nawo amapukutidwa ndi dothi, mafuta ndi ma oxides.
