Mzere wa sensor wa ABS wakutsogolo
Sensa ya abs imagwiritsidwa ntchito mu ABS (Anti-lock Braking System) ya galimoto. Makina ambiri a ABS amayang'aniridwa ndi sensa yoyendetsera galimoto kuti iwunikire liwiro la galimoto. Sensa ya abs imatulutsa seti yolondola. Mafupipafupi ndi kutalika kwa chizindikiro cha sinusoidal alternating current zimagwirizana ndi liwiro la gudumu. Chizindikiro chotulutsa chimatumizidwa ku ABS electronic control unit (ECU) kuti chiziwunikire liwiro la gudumu nthawi yeniyeni.
mitundu yayikulu
1. Chojambulira liwiro la gudumu lolunjika
Sensa yothamanga ya mawilo olunjika imapangidwa makamaka ndi maginito okhazikika, chitsulo cha pole, cholumikizira cholumikizira ndi cholumikizira cholumikizira. Pamene cholumikizira cholumikizira chizungulira, pamwamba pa dzino ndi kumbuyo kwa zingwe zimayang'ana mbali ya polar motsatizana. Pakuzungulira kwa cholumikizira cholumikizira, mphamvu ya maginito mkati mwa cholumikizira cholumikizira imasintha motsatizana kuti ipange mphamvu yamagetsi yoyendetsedwa, ndipo chizindikirochi chimalowetsedwa ku gawo lowongolera zamagetsi la ABS kudzera mu chingwe kumapeto kwa cholumikizira cholumikizira. Pamene liwiro la cholumikizira cholumikizira lisintha, kuchuluka kwa mphamvu yamagetsi yoyendetsedwa yoyendetsedwa imasinthanso.
2. Sensa yothamanga ya gudumu la mphete
Sensa ya liwiro la mawilo a annular imapangidwa makamaka ndi maginito okhazikika, coil yolowetsa ndi giya yozungulira. Maginito okhazikika amapangidwa ndi mapeyala angapo a maginito. Pakuzungulira kwa giya yozungulira, mphamvu ya maginito mkati mwa coil yolowetsa imasintha mosinthana kuti ipange mphamvu yamagetsi yoyendetsedwa. Chizindikiro ichi chimalowetsedwa ku gawo lowongolera zamagetsi la ABS kudzera mu chingwe kumapeto kwa coil yolowera. Pamene liwiro la giya yozungulira lisintha, kuchuluka kwa mphamvu yamagetsi yoyendetsedwa nayonso kumasintha.
3. Chojambulira liwiro la gudumu la holo
Giya ikafika pamalo omwe akuwonetsedwa mu (a), mizere ya mphamvu ya maginito yomwe imadutsa mu Hall element imafalikira, ndipo mphamvu ya maginito imakhala yofooka; pomwe giya ikafika pamalo omwe akuwonetsedwa mu (b), mizere ya mphamvu 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 kusintha kwa mphamvu ya Hall, ndipo gawo la Hall limatulutsa mphamvu ya quasi-sine wave ya millivolt (mV) level. Chizindikiro ichi chiyeneranso kusinthidwa kukhala mphamvu ya pulse yokhazikika ndi electronic circuit.
Ikani Sinthani Broadcast
(1) Zida zopondera mphete
Chida chozungulira ndi mphete yamkati kapena mandrel ya hub unit zimakhala ndi kusakanikirana. Pa nthawi yopangira hub unit, giya yozungulira ndi mphete yamkati kapena mandrel zimagwirizanitsidwa pamodzi ndi makina osindikizira a hydraulic;
(2) Ikani sensa
Pali mitundu iwiri ya mgwirizano pakati pa sensa ndi mphete yakunja ya hub unit: kulowerera ndi kutseka kwa nati. Sensa ya liwiro la gudumu lolunjika makamaka imakhala mu mawonekedwe a kutseka kwa nati, ndipo sensa ya liwiro la gudumu lozungulira imagwiritsa ntchito kulowerera;
Mtunda pakati pa pamwamba pa maginito okhazikika ndi pamwamba pa dzino la zida zoimbira: 0.5±0.15mm (makamaka umatsimikiziridwa poyang'anira m'mimba mwake wakunja kwa zida zoimbira, m'mimba mwake wamkati wa sensa ndi concentricity)
(3) Yesani magetsi Gwiritsani ntchito magetsi otulutsa magetsi ndi mawonekedwe a mafunde opangidwa nokha pa liwiro linalake, ndipo yesani ngati pali dera lalifupi la sensa yolunjika;
Liwiro: 900rpm
Kufunika kwa magetsi: 5. 3 ～7. 9v
Zofunikira pa mawonekedwe a waveform: mafunde olimba a sine
kuzindikira magetsi
Kuzindikira kwa voteji yotuluka
Zinthu zoyesera:
1. Voliyumu yotulutsa: 650 ～850mv (1 20rpm)
2. Mawonekedwe a mafunde otuluka: mafunde okhazikika a sine
Chachiwiri, mayeso okhazikika a sensor ya abs
Sungani sensa pa 40°C kwa maola 24 kuti muwone ngati sensa ya abs ikukwaniritsa zofunikira zamagetsi ndi kutseka kuti igwiritsidwe ntchito mwachizolowezi.
