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 backlash imasinthana ndi polar axis. Pakuzungulira kwa mphete ya giya, kusinthasintha kwa maginito mkati mwa koyilo yolowera 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.
Kodi chosweka chakumbuyo kwa abs sensor chimakhudza 4-drive
Mwina
Kuwonongeka kwa sensa yakumbuyo ya ABS kungakhudze makina oyendetsa magudumu onse, makamaka ngati makina oyendetsa magudumu onse ali ndi kutseka kosiyana. Izi ndichifukwa choti sensa yam'mbuyo yam'mbuyo imakhala ndi gawo lofunikira mu anti-lock braking system (ABS), ikawonongeka, dongosolo la ABS silingazindikire molondola kuthamanga ndi mawonekedwe a gudumu, zomwe zimakhudza kuphulika kwake, ndipo zimatha kutsogolera. pa gudumu loko pa mabuleki, kuonjezera ngozi yoyendetsa. Kuonjezera apo, ngati makina oyendetsa magudumu anayi ali ndi ntchito yosiyana ndi loko, kuwonongeka kwa sensa yam'mbuyo yam'mbuyo kungapangitse kuti kutsekeka kosiyana kusagwire ntchito bwino, zomwe zingakhudze machitidwe a magudumu anayi. Choncho, ngakhale kuwonongeka kwa sensa ya gudumu lakumbuyo sikungakhudze mwachindunji ntchito yofunikira ya makina oyendetsa magudumu anayi, pofuna kuonetsetsa kuti chitetezo chikuyenda bwino, tikulimbikitsidwa kukonzanso kapena kusintha sensa yowonongeka mu nthawi.
ABS kumbuyo gudumu sensa akhoza kulephera chifukwa kuvala. pa
Kulephera kwa sensa ya ABS kumaphatikizapo kuwala kwa ABS pa dashboard, ABS yosagwira ntchito bwino, ndi kuwala kowongolera mphamvu. Kulephera uku kungayambitsidwe ndi masensa akutha, kuchotsedwa, kapena kugundidwa ndi zinyalala. Makamaka gudumu lakumbuyo la ABS sensa, ngati zitsulo zachitsulo zopangidwa ndi kugaya kwa disc brake ndi brake pad zimakongoletsedwa ndi maginito, zingayambitse mtunda pakati pa sensa ndi maginito koyilo kukhala yaying'ono, kapena kuvala. , pamapeto pake kumabweretsa kuwonongeka kwa sensor. pa
Kuti muwone ngati sensa ya ABS yawonongeka, mutha kudziwika ndi njira zotsatirazi:
Werengani cholakwika cha chida chozindikira cholakwika: Ngati pali cholakwika mu kompyuta ya ABS, ndipo chowunikira pa chipangizocho chayatsidwa, izi zitha kuwonetsa kuti sensa yawonongeka. pa
Kuyesa kwa brake kumunda: mumsewu wabwino, malo otakata komanso osayendetsedwa, mwachangu mpaka kupitilira 60, kenako ikani brake mpaka kumapeto. Ngati gudumu latsekedwa ndipo palibe kukhumudwa kwa braking, izi zingasonyeze kulephera kwa ABS, nthawi zambiri zimayambitsidwa ndi kuwonongeka kwa sensa ya ABS. pa
Gwiritsani ntchito ma multimeter kuti muyese voteji / kukana kwa sensor ya ABS: Sinthani gudumu pa 1r / s, mphamvu yotulutsa gudumu lakutsogolo iyenera kukhala pakati pa 790 ndi 1140mv, gudumu lakumbuyo liyenera kukhala lalitali kuposa 650mv. Kuphatikiza apo, kukana kwa masensa a ABS nthawi zambiri kumakhala pakati pa 1000 ndi 1300Ω. Ngati mindandanda iyi sinakwaniritsidwe, zitha kuwonetsa vuto ndi sensor 34 ya ABS
Mwachidule, ngati pali vuto ndi sensa yakumbuyo ya ABS, muyenera kuyang'ana kaye ngati pali kuwonongeka kwakuthupi, monga kusweka kapena kuvala koonekeratu. Ngati palibe kuwonongeka kwa thupi komwe kukuwonekera chifukwa cha kuvala kapena zifukwa zina zitha kudziwikanso ndi njira zomwe zili pamwambazi. pa
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.
