ABS sensor.
Sensa ya Abs 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 nsonga zobwerera zimasinthana 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
Kuzindikira kwamagetsi
Kuzindikira mphamvu yamagetsi
Zoyendera:
1, linanena bungwe voteji: 650 ~ 850mv (1 20rpm)
2, mawonekedwe otuluka: khola sine wave
Chachiwiri, abs sensor otsika kutentha durability mayeso
Sungani kachipangizo pa 40 ° C kwa maola 24 kuti muwone ngati abs sensor imatha kukwaniritsa zofunikira zamagetsi ndi kusindikiza zomwe zimagwiritsidwa ntchito bwino.
Chifukwa chiyani sensor ya abs ndiyosavuta kusweka
Zifukwa zomwe sensor ya ABS ndiyosavuta kuwononga makamaka imaphatikizapo gawo la induction lomwe limaphimbidwa, mzerewu ndi wotayirira komanso mtundu wa sensor womwewo. Zambiri ndi izi:
Gawo lozindikira limaphimbidwa: gawo la sensor ya ABS litaphimbidwa ndi dothi, fumbi kapena matupi ena akunja, zimasokoneza kutulutsa kwa sensor, zomwe zimapangitsa kuti kompyuta isathe kuweruza molondola liwiro, zimakhudza magwiridwe antchito a brake system.
Mzere wotayirira: Kulumikizana kwa mzere wa sensa sikuli kolimba kapena cholumikizira ndi chotayirira, zomwe zingayambitse kusayenda bwino kwa ma sign, zomwe zimapangitsa kuti pakhale zolakwika. Cholakwika chofala ndichakuti nyali yoyipa imayaka.
Ubwino wa sensa palokha: ngati khalidwe la ABS sensa ndi osauka, zingakhudze kukhazikika kwa chizindikiro chake linanena bungwe, ndiyeno zimakhudza tilinazo ABS dongosolo ndi galimoto chitetezo.
Zinthu izi zingapangitse kuti sensa ya ABS iwonongeke mosavuta, choncho panthawi yogwiritsira ntchito ndi kukonza, chisamaliro chiyenera kulipidwa kuti chikhale choyera komanso kuyang'ana momwe mzere wolumikizira mzerewu ukuyendera.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
