Iyini inzwa ye-ABS engaphambili yemoto?
Inzwa ye-ABS engaphambili, eyaziwa nangokuthi inzwa yesivinini se-ABS evili langaphambili, iyisici esibalulekile sohlelo lokubhuleka lwemoto oluvimbela ukukhiya (i-ABS), oluklanyelwe ngqo ukuqapha isivinini sangempela samasondo angaphambili.
Umsebenzi wayo oyinhloko ukunikeza iyunithi yokulawula kagesi ye-ABS (ECU) idatha enembile ngesivinini samasondo angaphambili. Uma imoto ibhuleka ngokushesha, uma isondo langaphambili selizovala (ngokwehla kwesivinini ngokuzumayo), uhlelo lwe-ABS, ngokusekelwe esignalini ethunyelwe emuva yile sensor, luzolungisa ngokushesha amandla okubhuleka kwalelo sondo ukuze luvimbele ukukhiya ngokuphelele, ngaleyo ndlela luqinisekise ukuthi imoto ingagcina ukulawula kokuqondisa nokuzinza ngesikhathi sokubhuleka futhi igweme ukushelela noma ukulahlekelwa ukulawula.
Izici eziyinhloko kanye nomgomo wokusebenza
Indawo yokufaka: Ngokuvamile inamathele ku-steering shaft noma izingxenye zokumiswa kwamasondo angaphambili, eduze kwe-hub bearing, kanti i-sensing ephetheyo igcina isikhala esincane kakhulu kusuka ku-ring gear (noma i-magnetic-coded ring) efakwe ku-hub noma i-brake disc.
Isimiso sokusebenza: Izimoto eziningi zesimanje zisebenzisa izinzwa zikagesi-magnetic. Lapho isondo lijikeleza, amazinyo nemifantu yegiya lendandatho kuzoshintsha njalo insimu kamagnetic eduze kwenzwa, ngaleyo ndlela kubangele isignali yamanje eshintshanayo ye-sinusoidal enemvamisa kanye ne-amplitude ehambisana nesivinini sesondo kukhoyili. Lesi signali sidluliselwa kuyunithi yokulawula ye-ABS.
Izici zesignali: Ngesikhathi sokusebenza okuvamile, kungabonakala nge-oscilloscope ukuthi umphumela wayo uyigagasi le-sine eline-amplitude eyanda njengoba ijubane likhuphuka. Inani layo lokumelana livame ukuba phakathi kuka-800Ω no-2kΩ. Uma umphumela wokulinganisa u-0Ω (i-short circuit) noma u-infinity (i-open circuit), kubonisa ukuthi inzwa yonakele.
Umthelela wephutha kanye nokugcinwa kwalo
Umthelela wephutha: Uma inzwa ye-ABS yangaphambili yehluleka (njengokuphazamiseka kwesignali noma idatha engajwayelekile), uhlelo lwe-ABS ngeke lukwazi ukunquma ngokunembile umkhuba wokukhiya kwamasondo angaphambili ngesikhathi sokubhuleka okuphuthumayo, okungabangela amasondo angaphambili ukuthi avale ngesikhathi sokubhuleka okuphuthumayo, okunciphisa kakhulu ukuphathwa nokuphepha kwemoto. Ngalesi sikhathi, isibani sesixwayiso se-ABS kudeshibhodi sizokhanya.
Izimbangela ezivamile zephutha: Ikhanda lenzwa limbozwe ngemicu yensimbi noma ukungcola; igebe eliphakathi kwenzwa negiya lendandatho likhulu kakhulu noma lincane kakhulu; ikhebula lonakele, noma ipulaki liyagqwala; ikhoyili yangaphakathi yenzwa iyisekethe evulekile noma isethephu esifushane.
Iziphakamiso zokulungisa: Uma isibani se-ABS sivuliwe, ithuluzi lokuxilonga le-OBD lochwepheshe kufanele lisetshenziswe ukufunda ikhodi yephutha (njenge-C0115-C0120) ukuthola ukuthi iyiphi inzwa yesondo engasebenzi kahle. Hlola njalo ukuthi ukufakwa kwenzwa kuqinile yini, nokuthi kukhona yini umonakalo ezintanjeni, futhi ugcine indawo yokuzwa kwenzwa ihlanzekile. Ngemva kokushintsha amathayi noma ukwenza ukulungiswa kwamasondo amane, kungadingeka ukuthi uphinde ulinganise inzwa.
Inzwa ye-ABS yesondo langaphambili emotweni iyisici esibalulekile sohlelo lokuphepha lwemoto. Umsebenzi wayo oyinhloko ukuqapha isivinini sangempela samasondo angaphambili nokudlulisa izimpawu zesivinini sesondo eziqondile kuyunithi yokulawula kagesi yemoto (i-ECU), ihlinzeka ngokusekelwa kwedatha eyisisekelo kwezinhlelo eziningi zokuphepha.
Imisebenzi ethile ingafingqwa kanje:
Umsebenzi oyinhloko: Qinisekisa ukuphepha kokubhuleka
Vimbela ukukhiywa kwesondo: Ngesikhathi sokubhuleka okuphuthumayo, inzwa ye-ABS yesondo langaphambili ingathola izinguquko esivinini sesondo ezingeni le-millisecond. Uma isithola ukuthi isondo langaphambili selizokhiywa (ngokwehla kwesivinini ngokuzumayo), i-module yokulawula i-ABS izonciphisa noma inqume ngokushesha amandla okubhuleka alelo sondo nge-valve kagesi, ivumele isondo ukuthi liphinde lijikeleze, bese lisebenzisa amandla okubhuleka futhi, lenze umjikelezo "wokukhulula ukukhiywa". Le nqubo igcina isondo langaphambili lisesimweni esihle "sokugingqika", ikhulisa ukungqubuzana okungaguquki phakathi kwethayi nomhlabathi, inciphise kakhulu ibanga lokubhuleka futhi igweme ukulahlekelwa ukulawula kwemoto, ukushelela, noma ukubaleka.
Thuthukisa ukusebenza kahle kokubhuleka: Ngokuphendula isivinini sesondo ngokunembile, uhlelo lwe-ABS lungalungisa amandla okubhuleka ngokuguquguqukayo, luqinisekise ukuthi amasondo angaphambili athola amandla okubhuleka afanele ngaphansi kwanoma yiziphi izimo zomgwaqo (ikakhulukazi emigwaqweni emanzi neshelelayo), okuthuthukisa ukusebenza kokubhuleka okuphelele.
Imisebenzi ebalulekile yokusiza Ukutholwa Kwesivinini Semoto: Isivinini semoto kanye nedatha yamamayela aboniswa kudeshibhodi kubalwa kakhulu ngokusekelwe kuzimpawu zesivinini sesondo ezivela kuzinzwa ze-ABS zamasondo angaphambili (nangemuva). Ingenye yemithombo eyinhloko yolwazi lwesivinini semoto.
Ukuqapha Ukucindezeleka Kwamathayi Okungaqondile: Ezimotweni ezifakwe uhlelo lokuqapha ukucindezeleka kwamathayi olungaqondile (i-TPMS), inzwa ye-ABS iqhathanisa umehluko wesivinini sokujikeleza kwamasondo amane ukuze inqume ukuthi ukucindezeleka kwamathayi akujwayelekile yini. Uma ukucindezeleka komoya kwethayi elithile (njengethayi langaphambili) kunganele, irediyasi yalo yokugoqa iba ncane, futhi isivinini salo sokujikeleza sizoba phezulu kunesamanye amathayi avamile. Uhlelo lube seluqala i-alamu yokucindezeleka kwamathayi ngokufanele.
Uhlelo Lokuzinza Komzimba Olusizayo (ESP/ESC): Izinzwa zamasondo angaphambili ziwumthombo wedatha obalulekile wohlelo lwe-ESP. Ngesikhathi sokuqondisa noma ukushayela emigwaqweni eshelelayo, uhlelo lubona ngokushesha ukuthi imoto inenkinga yokushelela eceleni noma ayiqondi ngokwanele/idlula ngokuqhathanisa umehluko wejubane lokujikeleza phakathi kwamasondo angaphambili nangemuva, bese lufaka ngokuzenzakalelayo ukubhuleka kumasondo ngamanye noma lulungise ukuphuma kwenjini ukuze kuqiniswe ukuma kwemoto.
Ukuqapha Amabhothi Amathayi Akhululekile (kwamanye amamodeli): Kwamanye amabhrendi (njengeVolkswagen, Audi, BYD), inzwa ye-ABS ingasiza ekunqumeni ukuthi amabhothi ethayi langaphambili akhululekile yini ngokuqapha ukushintshashintsha okuncane kwesivinini sesondo, bese iqalisa isixwayiso sokuphepha esifanele.
Umphumela Wamaphutha
Uma inzwa ye-ABS yesondo langaphambili ihluleka (njengokumbozwa uthuli, ukuba ne-wiring harness eyonakele, noma ukulimala ngaphakathi), kuzoholela ku:
Isibani se-ABS esisedeshibhodini siyakhanya, kanti kwezinye izimoto, izibani zokuqapha umfutho wamathayi ze-ESP/ESC nazo ziyakhanya ngasikhathi sinye.
Ukwehluleka kwesistimu ye-ABS: Ngesikhathi sokubhuleka okuphuthumayo, amasondo angase avale ngokuphelele, alahlekelwe ikhono lokulawula isiqondiso.
Ukwehla kwesistimu ye-ESP: Ukuqina kwemoto kwehla emigwaqweni eshelelayo noma ngesikhathi sokugwema okuphuthumayo.
Isibonisi sejubane lemoto esingajwayelekile: Ezinye izimoto zingase zibe ne-speedometer engasebenzi kahle noma ukubalwa kwamamayela okungalungile.
Ngakho-ke, yize inzwa ye-ABS yesondo langaphambili ingakhiqizi ngqo amandla okubhuleka, "iziphetho zemizwa" eziqinisekisa ukuphepha kokubhuleka, ukuzinza kwemoto, kanye nokusebenza okuvamile kwemisebenzi eminingi ehlakaniphile. Ukuthembeka kwayo kuthinta ngqo ukuphepha kokushayela.
