Front ABS sensor mzere
Sensa ya abs imagwiritsidwa ntchito mu ABS (Anti-lock Braking System) yagalimoto.Makina ambiri a ABS amayang'aniridwa ndi sensor inductive kuti iwonetse kuthamanga kwagalimoto.The abs sensor imatulutsa zolondola Mafupipafupi ndi matalikidwe a sinusoidal alternating signal panopa amagwirizana ndi liwiro la gudumu.Chizindikiro chotulutsa chimatumizidwa ku ABS electronic control unit (ECU) kuti muzindikire kuwunika kwenikweni kwa liwiro la gudumu.
mitundu yayikulu
1. Liniya gudumu liwiro kachipangizo
Liniya wheel speed sensor imapangidwa makamaka ndi maginito okhazikika, shaft yamtengo, coil induction ndi giya la mphete.Pamene mphete imazungulira, nsonga za dzino ndi zobwerera kumbuyo zimayang'ana polar axis mosinthana.Panthawi yozungulira giya la mphete, kusinthasintha kwa maginito mkati mwa coil induction kumasintha mosinthana kuti apange mphamvu yamagetsi yamagetsi, ndipo chizindikirochi chimalowetsedwa kugawo lamagetsi la ABS kudzera pa chingwe kumapeto kwa koyilo yolowera.Liwiro la giya la mphete likasintha, ma frequency a induced electromotive force amasinthanso.
2. mphete gudumu liwiro sensa
The annular wheel speed sensor imapangidwa makamaka ndi maginito osatha, coil induction and ring gear.Maginito okhazikika amapangidwa ndi mapeyala angapo amitengo yamaginito.Pozungulira giya la mphete, kusinthasintha kwa maginito mkati mwa coil induction kumasintha mosinthana kuti apange mphamvu ya electromotive.Chizindikirochi chimalowetsedwa ku gawo lowongolera zamagetsi la ABS kudzera pa chingwe kumapeto kwa koyilo yolowera.Liwiro la giya la mphete likasintha, ma frequency a induced electromotive force amasinthanso.
3. Hall gudumu liwiro sensa
Pamene giya ili pamalo omwe akuwonetsedwa mu (a), mizere yamphamvu ya maginito yodutsa mu Hall element imamwazika, ndipo mphamvu ya maginito imakhala yofooka;pamene giya ili pamalo omwe akuwonetsedwa mu (b), mizere yamphamvu ya maginito yodutsa mu Hall element imakhazikika, ndipo mphamvu ya maginito imakhala yamphamvu kwambiri .Magiya akamazungulira, kachulukidwe ka maginito odutsa mu Hall amasintha, zomwe zimapangitsa kusintha kwamagetsi aku Hall, ndipo gawo la Hall limatulutsa mulingo wa quasi-sine wave wa millivolt (mV).Chizindikirochi chimafunikanso kusinthidwa kukhala voteji yokhazikika ndi dera lamagetsi.
Ikani Sinthani Broadcast
(1) Chidindo cha mphete
Zida za mphete ndi mphete yamkati kapena mandrel a unit hub zimatengera kusokoneza.Panthawi ya msonkhano wa unit hub, giya la mphete ndi mphete yamkati kapena mandrel amaphatikizidwa pamodzi ndi makina osindikizira a hydraulic;
(2) Ikani sensa
Pali mitundu iwiri ya mgwirizano pakati pa sensa ndi mphete yakunja ya hub unit: kusokoneza kokwanira ndi kutseka mtedza.Liniya gudumu liwiro sensa makamaka mu mawonekedwe a mtedza kutseka, ndi annular gudumu liwiro sensa utenga kusokoneza zoyenera;
Mtunda pakati pa pamwamba pa maginito okhazikika ndi dzino pamwamba pa mphete giya: 0.5 ± 0.15mm (makamaka kuonetsetsa ndi kulamulira awiri akunja a mphete giya, m'mimba mwake wamkati wa sensa ndi concentricity)
(3) Magetsi oyesera Gwiritsani ntchito mphamvu yodzipangira yokhayokha ndi ma waveform pa liwiro linalake, ndikuyesa ngati pali kagawo kakang'ono ka sensa ya mzere;
Liwiro: 900rpm
Kufunika kwa magetsi: 5. 3 ~ 7.9v ndi
Zofunikira za Waveform: stable sine wave
kuzindikira voteji
Kuzindikira mphamvu yamagetsi
Zinthu zoyeserera:
1. Mphamvu yamagetsi: 650 ~ 850mv (1 20rpm)
2. Kutulutsa mawonekedwe: mawonekedwe okhazikika a sine
Chachiwiri, abs sensor otsika kutentha durability mayeso
Sungani sensor pa 40 ° C kwa maola 24 kuti muwone ngati abs sensor imatha kukwaniritsa zofunikira zamagetsi ndi kusindikiza kuti mugwiritse ntchito bwino.
