Kodi Sensor ya ABS yakumbuyo ndi chiyani? Kodi pali mitundu yanji ndipo imayikidwa bwanji?
Sensa ya abs imagwiritsidwa ntchito mu ABS yagalimoto (Anti-lock Braking System). Mu dongosolo la ABS, liwiro limayang'aniridwa ndi sensa yoyambitsa. Sensa ya abs imatulutsa zizindikiro zamagetsi za AC zomwe zimakhala ngati sinusoidal kudzera mu ntchito ya mphete ya giya yomwe imazungulira mogwirizana ndi gudumu, ndipo mafupipafupi ake ndi kukula kwake zimagwirizana ndi liwiro la gudumu. Chizindikiro chotulutsa chimatumizidwa ku ABS electronic control unit (ECU) kuti chiziyang'anira liwiro la gudumu nthawi yeniyeni.
1, sensa yothamanga ya gudumu lolunjika
Sensa yothamanga ya mawilo a mzere imapangidwa makamaka ndi maginito okhazikika, pole axis, induction coil ndi tooth ring. Pamene giya likuzungulira, nsonga ya giya ndi backlash zimasinthasintha motsatizana ndi polar axis. Panthawi yozungulira giya, maginito mkati mwa induction coil amasintha motsatizana kuti apange induction electromotive force, ndipo chizindikirochi chimalowetsedwa ku electronic control unit ya ABS kudzera mu chingwe kumapeto kwa induction coil. Pamene liwiro la giya likusinthasintha, kuchuluka kwa mphamvu yoyendetsera electromotive yomwe yayambitsidwa kumasinthanso.
2, sensa ya liwiro la gudumu lozungulira
Sensa yothamanga ya mawilo angular imapangidwa makamaka ndi maginito okhazikika, cholumikizira cha induction ndi mphete ya dzino. Maginito okhazikika amapangidwa ndi mapeyala angapo a maginito. Pakuzungulira kwa mphete ya giya, mphamvu ya maginito mkati mwa cholumikizira cha induction imasintha mosinthana kuti ipange mphamvu ya induction electromotive. Chizindikiro ichi chimalowetsedwa ku chipangizo chowongolera zamagetsi cha ABS kudzera mu chingwe chomwe chili kumapeto kwa cholumikizira cha induction. Pamene liwiro la mphete ya giya lisintha, kuchuluka kwa mphamvu ya electromotive yomwe imayambitsa imasinthanso.
3, Sensor ya liwiro la gudumu la mtundu wa Hall
Giya ikapezeka pamalo omwe akuwonetsedwa mu (a), mizere ya maginito yomwe imadutsa mu Hall element imafalikira ndipo mphamvu ya maginito imakhala yofooka; Giya ikapezeka pamalo omwe akuwonetsedwa mu (b), mizere ya maginito yomwe imadutsa mu Hall element imakhala yokhazikika ndipo mphamvu ya maginito imakhala yamphamvu. Giya ikazungulira, kuchuluka kwa mphamvu ya maginito yomwe imadutsa mu Hall element kumasintha, zomwe zimapangitsa kuti mphamvu ya Hall isinthe, ndipo gawo la Hall limatulutsa mulingo wa millivolt (mV) wa quasi-sine wave voltage. Chizindikiro ichi chimafunikanso kusinthidwa ndi electronic circuit kukhala voltage yokhazikika ya pulse.
Ikani
(1) Mphete yopondera zida
Mphete ya dzino ndi mphete yamkati kapena mandrel ya hub unit zimakhala ndi kusakanikirana koyenera. Pogwirizanitsa hub unit, mphete ya dzino ndi mphete yamkati kapena mandrel zimagwirizanitsidwa pamodzi pogwiritsa ntchito mafuta.
(2) Ikani sensa
Kugwirizana pakati pa sensa ndi mphete yakunja ya hub unit ndi kulowererana pakati pa kulowererana ndi kutsekeka kwa nati. Sensa ya liwiro la gudumu lolunjika makamaka imakhala yofanana ndi loko la nati, ndipo sensa ya liwiro la gudumu lozungulira imagwiritsa ntchito kulowererana pakati pa kulowererana.
Mtunda pakati pa pamwamba pa maginito okhazikika ndi pamwamba pa dzino la mphete: 0.5 ± 0.15 mm (makamaka kudzera mu ulamuliro wa m'mimba mwake wakunja wa mphete, m'mimba mwake wamkati wa sensa ndi concentricity)
(3) Voltage yoyesera imagwiritsa ntchito voteji yotulutsa yaukadaulo yodzipangira yokha ndi mawonekedwe a waveform pa liwiro linalake, ndipo sensa yolunjika iyeneranso kuyesa ngati dera lalifupi ndi lolondola;
Liwiro: 900rpm
Kufunika kwa magetsi: 5.3 ~ 7.9 V
Zofunikira pa mawonekedwe a waveform: mafunde olimba a sine
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MGZigawo zamagalimoto za &MAUXS ndizolandiridwa kugula.
