Yintoni i-sensor ye-ABS engaphambili yemoto?
I-ABS sensor yangaphambili, eyaziwa ngokuba yi-ABS speed sensor yevili elingaphambili, yinxalenye ebalulekileyo yenkqubo ye-anti-lock braking (ABS) yesithuthi, eyenzelwe ngokukodwa ukujonga isantya sevili elingaphambili ngexesha langempela.
Umsebenzi wayo oyintloko kukubonelela iyunithi yolawulo lwe-elektroniki ye-ABS (ECU) ngedatha echanekileyo malunga nesantya samavili angaphambili. Xa imoto ibhuleka ngokukhawuleza, ukuba ivili elingaphambili liza kutshixeka (ngokwehla kwesantya ngequbuliso), inkqubo ye-ABS, ngokusekelwe kumqondiso othunyelwe ngulo senzwa, iya kulungisa ngokukhawuleza amandla okubhuleka kwevili ukuze ithintele ukutshixeka ngokupheleleyo, ngaloo ndlela iqinisekisa ukuba isithuthi sinokugcina ulawulo lokuqhuba kunye nozinzo ngexesha lokubhuleka kwaye siphephe ukutyibilika okanye ukulahleka kolawulo.
Iimpawu eziphambili kunye nomgaqo wokusebenza
Indawo yokufakelwa: Ihlala inamathele kwi-steering shaft okanye kwi-suspension components yamavili angaphambili, kufutshane ne-hub bearing, apho isiphelo sayo sokuva sigcina umsantsa omncinci kakhulu kwi-ring gear (okanye i-magnetic-coded ring) efakwe kwi-hub okanye kwi-brake disc.
Umgaqo wokusebenza: Uninzi lweemoto zanamhlanje zisebenzisa ii-sensors ze-magnetic-electric. Xa ivili lijikeleza, amazinyo kunye nemingxunya yegiya yeringi ziya kutshintsha rhoqo intsimi ye-magnetic kufutshane ne-sensor, ngaloo ndlela zibangela isignali ye-sinusoidal alternating current ene-frequency kunye ne-amplitude ehambelana nesantya sevili kwi-coil. Esi signali sidluliselwa kwiyunithi yolawulo lwe-ABS.
Iimpawu zeSignali: Ngexesha lokusebenza okuqhelekileyo, kunokubonwa nge-oscilloscope ukuba imveliso yayo yi-sine wave ene-amplitude eyandayo njengoko isantya sinyuka. Ixabiso layo lokumelana lidla ngokuba phakathi kwe-800Ω kunye ne-2kΩ. Ukuba isiphumo sokulinganisa yi-0Ω (i-short circuit) okanye i-infinity (i-open circuit), oko kubonisa ukuba i-sensor yonakele.
Impembelelo kunye nokugcinwa kwempazamo
Impembelelo yempazamo: Ukuba isenzi se-ABS esingaphambili siyasilela (njengokuphazamiseka kwesignali okanye idatha engaqhelekanga), inkqubo ye-ABS ayizukukwazi ukumisela ngokuchanekileyo umkhwa wokutshixa kwamavili angaphambili ngexesha lokuqhobosha ngexesha longxamiseko, nto leyo enokubangela ukuba amavili angaphambili aqhobosheke ngexesha lokuqhobosha ngexesha longxamiseko, nto leyo enciphisa kakhulu ukuphathwa kwesithuthi kunye nokhuseleko lwaso. Ngeli xesha, isibane sesilumkiso se-ABS kwideshibhodi siya kukhanyisa.
Izizathu eziqhelekileyo zokungasebenzi kakuhle: Intloko yesensa igqunywe ziingceba zentsimbi okanye ukungcola; umsantsa phakathi kwesensa kunye negiya yeringi mkhulu kakhulu okanye mncinci kakhulu; intambo yonakele, okanye iplagi igqwalile; ikhoyili yangaphakathi yesensa yisekethe evulekileyo okanye isekethe emfutshane.
Iingcebiso zokulungisa: Xa isibane se-ABS sivuliwe, kufuneka kusetyenziswe isixhobo sobuchwephesha sokuxilonga i-OBD ukufunda ikhowudi yempazamo (efana ne-C0115-C0120) ukuze kufunyanwe ukuba yeyiphi inzwa yevili engasebenzi kakuhle. Jonga rhoqo ukuba ufakelo lwenzwa luqinile na, kwaye ukuba kukho umonakalo kwiintambo, kwaye ugcine indawo yokuva inzwa icocekile. Emva kokutshintsha amatayara okanye ukwenza ulungelelwaniso lwamavili amane, kunokufuneka ukuba uhlengahlengise kwakhona inzwa.
I-ABS sensor yevili elingaphambili emotweni yinxalenye ebalulekileyo yenkqubo yokhuseleko lwesithuthi. Umsebenzi wayo ophambili kukujonga isantya sevili elingaphambili ngexesha langempela nokuthumela imiqondiso yesantya sevili echanekileyo kwiyunithi yolawulo lwe-elektroniki yesithuthi (ECU), ukubonelela ngenkxaso yedatha esisiseko kwiinkqubo ezininzi zokhuseleko.
Imisebenzi ethile ingashwankathelwa ngolu hlobo lulandelayo:
Umsebenzi oyintloko: Qinisekisa ukhuseleko lokubhuleka
Ukuthintela ukutshixwa kwevili: Ngexesha lokuqhobosheka okungxamisekileyo, i-ABS sensor yevili elingaphambili inokubona utshintsho kwisantya sevili kwinqanaba le-millisecond. Nje ukuba ifumanise ukuba ivili elingaphambili liza kuqhobosheka (ngokwehla kwesantya ngequbuliso), imodyuli yolawulo lwe-ABS iya kunciphisa okanye inqumle ngoko nangoko amandla okuqhobosheka kwevili ngevalvu ye-electromagnetic, ivumele ivili ukuba liphinde lijikeleze, ize isebenzise amandla okuqhobosheka kwakhona, yenze umjikelo "wokukhulula ukuqhobosheka". Le nkqubo igcina ivili elingaphambili likwimeko efanelekileyo "yokuqengqeleka-ukutyibilika", ikhulisa ukungqubana okungaguqukiyo phakathi kwetayara nomhlaba, inciphisa kakhulu umgama wokuqhobosheka kwaye iphephe ukulahleka kolawulo lwesithuthi, ukutyibilika, okanye ukubaleka.
Ukuphucula ukusebenza kakuhle kokuqhobosha: Ngokuphendula ngokuchanekileyo isantya sevili, inkqubo ye-ABS inokutshintsha amandla okuqhobosha, iqinisekise ukuba amavili angaphambili afumana amandla okuqhobosha afanelekileyo phantsi kwayo nayiphi na imeko yendlela (ingakumbi kwiindlela ezimanzi nezityibilikayo), iphucula ukusebenza kokuqhobosha ngokubanzi.
Imisebenzi ebalulekileyo yokuncedisa Ukuchonga isantya sesithuthi: Idatha yesantya sesithuthi kunye neekhilomitha eziboniswa kwideshibhodi ibalwa kakhulu ngokusekelwe kwimiqondiso yesantya sevili evela kwiisensa ze-ABS zamavili angaphambili (nangasemva). Ngomnye wemithombo ephambili yolwazi lwesantya sesithuthi.
Ukujonga Uxinzelelo Lwamatayara Ngokungathanga Ngqo: Kwizithuthi ezixhotyiswe ngenkqubo yokujonga uxinzelelo lwamatayara ngokungathanga ngqo (TPMS), i-ABS sensor ithelekisa umahluko wesantya sokujikeleza kwamavili amane ukuze ibone ukuba uxinzelelo lwamatayara aluqhelekanga na. Xa uxinzelelo lomoya lwetayara ethile (njengetayara yangaphambili) lunganele, i-radius yayo eqengqelekayo iba ncinci, kwaye isantya sayo sokujikeleza siya kuba phezulu kunezinye iitayara eziqhelekileyo. Inkqubo emva koko ivula i-alamu yoxinzelelo lwamatayara ngokufanelekileyo.
Inkqubo Yokuzinza Komzimba Oncedisayo (ESP/ESC): Izinzwa zamavili angaphambili zingumthombo wedatha obalulekileyo kwinkqubo ye-ESP. Ngexesha lokuqhuba okanye ukuqhuba kwiindlela ezityibilikayo, inkqubo ikhawuleza ichonge ukuba imoto inengxaki yokutyibilika ecaleni okanye ukujika okunganelanga/ukujika ngaphezulu ngokuthelekisa umahluko wesantya sokujikeleza phakathi kwamavili angaphambili nangasemva, kwaye ifake ngokuzenzekelayo ukuqhobosha kumavili ngamanye okanye ilungise amandla enjini ukuze izinzise ukuma kwesithuthi.
Ukubeka esweni iiBolts zamaTayi ezikhululekileyo (kwezinye iimodeli): Kwezinye iimpawu (ezifana neVolkswagen, Audi, BYD), i-ABS sensor inokunceda ekuqinisekiseni ukuba iibolts zamatayara angaphambili zikhululekile na ngokubeka esweni ukuguquguquka okuncinci kwisantya sevili, kwaye iqalise isilumkiso sokhuseleko esifanelekileyo.
Impembelelo yeempazamo
Ukuba i-ABS sensor yevili langaphambili ayisebenzi (njengokugqunywa luthuli, ukuba ne-wiring harness eyonakeleyo, okanye ukuba yonakele ngaphakathi), kuya kubangela oku kulandelayo:
Isibane se-ABS esikwideshibhodi siyakhanya, kwaye kwezinye izithuthi, izibane ze-ESP/ESC okanye zokujonga uxinzelelo lwamatayara nazo ziyakhanya ngaxeshanye.
Ukusilela kwenkqubo ye-ABS: Ngexesha lokubhuleka okungxamisekileyo, amavili anokutshixeka ngokupheleleyo, alahlekelwe kukwazi ukulawula icala.
Ukwehla kwenkqubo ye-ESP: Uzinzo lwesithuthi luyancipha kwiindlela ezityibilikayo okanye ngexesha lokuphepha ungxamiseko.
Umboniso wesantya sesithuthi ongaqhelekanga: Ezinye izithuthi zinokuba ne-speedometer engasebenzi kakuhle okanye ubalo lwemayile olungachanekanga.
Ngoko ke, nangona isenzi se-ABS esikwivili elingaphambili singavelisi ngqo amandla okuqhobosha, "ziziphelo zemithambo-luvo" eziqinisekisa ukhuseleko lokuqhobosha, uzinzo lwesithuthi, kunye nokusebenza okuqhelekileyo kwemisebenzi emininzi ekrelekrele. Ukuthembeka kwayo kuchaphazela ngqo ukhuseleko lokuqhuba.
