Kodi Rear ABS Sensor ndi chiyani?Ndi mitundu yanji yomwe ilipo ndipo imayikidwa bwanji?
abs sensor imagwiritsidwa ntchito mugalimoto ya ABS (Anti-lock Braking System).Mu dongosolo la ABS, liwiro limayang'aniridwa ndi sensor inductive.Sensa ya abs imatulutsa ma siginecha amagetsi a quasi-sinusoidal AC kudzera mukuchita kwa mphete ya giya yomwe imazungulira molumikizana ndi gudumu, ndipo ma frequency ake ndi matalikidwe ake amagwirizana ndi liwiro la gudumu.Chizindikiro chotuluka chimatumizidwa ku ABS electronic control unit (ECU) kuti muzindikire kuwunika kwenikweni kwa liwiro la gudumu.
1, liniya gudumu liwiro sensa
Linear wheel speed sensor imapangidwa makamaka ndi maginito osatha, pole axis, coil induction ndi mphete ya mano.Pamene mphete ya giya imazungulira, nsonga ya giya ndi backlash imasinthana ndi polar axis.Pakuzungulira kwa mphete ya giya, 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 mphete ya giya likasintha, ma frequency a induced electromotive force amasinthanso.
2, ring wheel speed sensor
Annular wheel speed sensor imapangidwa makamaka ndi maginito osatha, coil induction ndi mphete ya mano.Maginito okhazikika amapangidwa ndi mapeyala angapo amitengo yamaginito.Pakuzungulira kwa mphete ya giya, kusinthasintha kwa maginito mkati mwa coil induction kumasintha mosinthana kuti apange induction electromotive force.Chizindikirochi chimalowetsedwa ku gawo lowongolera zamagetsi la ABS kudzera pa chingwe kumapeto kwa coil induction.Liwiro la mphete ya giya likasintha, ma frequency a induced electromotive force amasinthanso.
3, Hall mtundu gudumu liwiro sensa
Pamene giya ili pamalo omwe akuwonetsedwa mu (a), mizere ya maginito yodutsa mu Hall element imamwazika ndipo mphamvu ya maginito imakhala yofooka;Pamene giya ili pamalo omwe akuwonetsedwa mu (b), mizere ya maginito yodutsa mu Hall element imakhazikika ndipo mphamvu ya maginito imakhala yamphamvu.Magiya akamazungulira, kachulukidwe ka maginito amphamvu odutsa mu Hall amasintha, zomwe zimapangitsa kuti magetsi a Hall asinthe, ndipo chinthu cha Hall chimatulutsa millivolt (mV) ya quasi-sine wave voltage.Chizindikirochi chiyeneranso kusinthidwa ndi dera lamagetsi kuti likhale voteji yokhazikika.
Ikani
(1) Chidindo cha mphete
Mng'oma ya dzino ndi mphete yamkati kapena mandrel a unit hub amatengera kusokoneza.Posonkhanitsira kagawo kakang'ono, mphete ya dzino ndi mphete yamkati kapena mandrel amaphatikizidwa pamodzi ndi makina osindikizira mafuta.
(2) Ikani sensa
Kukwanira pakati pa sensa ndi mphete yakunja ya hub unit ndikusokoneza kokwanira ndi loko ya nati.Sensa yothamanga yama wheel wheel ndi mawonekedwe a nut loko, ndipo sensa ya ring wheel imatengera kusokoneza.
Mtunda pakati pa mkati mwa maginito okhazikika ndi dzino pamwamba pa mphete: 0.5 ± 0.15 mm (makamaka kudzera mu kulamulira kwa m'mimba mwake kunja kwa mphete, m'mimba mwake mkati mwa sensa ndi concentricity)
(3) Magetsi oyeserera amagwiritsa ntchito voliyumu yodzipangira yokhayokha ndi ma waveform pa liwiro linalake, ndipo sensa ya mzere iyeneranso kuyesa ngati dera lalifupi;
Liwiro: 900rpm
Mphamvu yamagetsi: 5.3 ~ 7.9 V
Zofunikira za Waveform: stable sine wave
