Inzwa ye-ABS.
Inzwa ye-Abs isetshenziswa ku-ABS yemoto (Uhlelo Lokubhuleka Olungakhiywa). Kuhlelo lwe-ABS, ijubane liqashwa yinzwa yokungenisa. Inzwa ye-abs ikhipha isethi yezimpawu zikagesi ze-AC ezingama-quasi-sinusoidal ngesenzo sendandatho yegiya ejikeleza ngokuvumelana nesondo, futhi imvamisa kanye nobukhulu bayo kuhlobene nesivinini sesondo. Isignali yokukhipha idluliselwa kuyunithi yokulawula kagesi ye-ABS (ECU) ukuze kuqashwe isivinini sesondo ngesikhathi sangempela.
1, inzwa yesivinini sesondo eliqondile
Inzwa yesivinini samasondo aqondile yakhiwe kakhulu ngemagnethi ehlala njalo, i-pole axis, i-induction coil kanye ne-tooth ring. Lapho indandatho yegiya ijikeleza, isihloko segiya kanye ne-backlash kuyashintshana ngokuphambene ne-polar axis. Ngesikhathi sokujikeleza kwendandatho yegiya, i-magnetic flux ngaphakathi kwe-induction coil iyashintsha ngokushintshana ukuze ikhiqize amandla e-electromotive e-induction, futhi lesi siginali singena kuyunithi yokulawula kagesi ye-ABS ngekhebula ekugcineni kwe-induction coil. Lapho ijubane lendandatho yegiya lishintsha, imvamisa yamandla e-electromotive ebangelwayo nayo iyashintsha.
2, inzwa yesivinini sesondo eliyindandatho
Inzwa yesivinini samasondo e-annular yakhiwe kakhulu yimagnethi ehlala njalo, ikhoyili yokungenisa kanye nendandatho yamazinyo. Imagnethi ehlala njalo yakhiwe ngamabhangqa amaningana ezigxobo zikagesi. Ngesikhathi sokujikeleza kwendandatho yegiya, i-magnetic flux ngaphakathi kwekhoyili yokungenisa iyashintsha ngokushintshana ukuze ikhiqize amandla e-electromotive okungenisa. Lesi siginali sifakwa kuyunithi yokulawula kagesi ye-ABS ngekhebula ekugcineni kwekhoyili yokungenisa. Lapho ijubane lendandatho yegiya lishintsha, imvamisa yamandla e-electromotive abangelwayo nayo iyashintsha.
3, inzwa yesivinini sesondo sohlobo lweHholo
Uma igiya lisendaweni eboniswe ku-(a), imigqa yensimu yamagnetic edlula ku-Hall element iyahlakazeka kanti insimu yamagnetic ibuthakathaka; Uma igiya lisendaweni eboniswe ku-(b), imigqa yensimu yamagnetic edlula ku-Hall element iyagxila futhi insimu yamagnetic inamandla kakhulu. Uma igiya lijikeleza, ubuningi bomugqa wamandla wamagnetic odlula ku-Hall element buyashintsha, okubangela ukuthi i-Hall voltage ishintshe, futhi i-Hall element izokhipha izinga le-millivolt (mV) le-quasi-sine wave voltage. Lesi siginali sidinga futhi ukuguqulwa yisekethe ye-elekthronikhi ibe yi-voltage ejwayelekile ye-pulse.
Ingabe inzwa yesisu ephukile yangemuva ithinta ama-drive angu-4
Kungenzeka
Ukulimala kwenzwa ye-ABS yangemuva kungathinta uhlelo lokushayela olunamasondo onke, ikakhulukazi uma uhlelo lokushayela olunamasondo onke lune-differential locking. Lokhu kungenxa yokuthi inzwa yesondo langemuva idlala indima ebalulekile ohlelweni lokushayela olulwa nokukhiya (i-ABS), uma selonakele, uhlelo lwe-ABS lungase lungaqondi kahle ijubane nesimo sesondo, okuthinta umphumela walo wokukhiya, futhi kungaholela nasekukhiyweni kwesondo ngesikhathi sokukhiya, okwandisa ingozi yokushayela. Ngaphezu kwalokho, uma uhlelo lokushayela olunamasondo amane lune-differential lock function, umonakalo wenzwa yesondo langemuva ungabangela ukuthi i-differential lock ingasebenzi kahle, okuzothinta ukusebenza kohlelo lokushayela olunamasondo amane. Ngakho-ke, yize umonakalo wenzwa yesondo langemuva ungase ungathinti ngqo umsebenzi oyisisekelo wohlelo lokushayela olunamasondo amane, ukuze kuqinisekiswe ukuphepha kokushayela, kunconywa ukulungisa noma ukushintsha inzwa eyonakele ngesikhathi.
Inzwa yesondo langemuva le-ABS ingase yehluleke ngenxa yokuguga.
Ukwehluleka kwenzwa ye-ABS kufaka phakathi ukukhanya kwe-ABS kudeshibhodi, i-ABS engasebenzi kahle, kanye nokukhanya kokulawula ukudonsa. Lokhu kwehluleka kungabangelwa ukuguga kwezinzwa, ukunqamula, noma ukushaywa yimfucumfucu. Ikakhulukazi inzwa ye-ABS yesondo langemuva, uma izingcezu zensimbi ezikhiqizwa ukugaywa kwediski yebhuleki kanye nephedi yebhuleki zidonswa yimagnethi, kungaholela ebangeni eliphakathi kwenzwa kanye nekhoyili yemagnethi libe lincane, noma liguge, ekugcineni kuholele ekulimaleni kwenzwa.
Ukuze kutholakale ukuthi inzwa ye-ABS yonakele yini, ingatholakala ngezindlela ezilandelayo:
Funda ikhodi yephutha yethuluzi lokuxilonga amaphutha: Uma kukhona ikhodi yephutha kukhompyutha ye-ABS, futhi isibani sephutha kuthuluzi sivuliwe, lokhu kungabonisa ukuthi inzwa yonakele.
Ukuhlolwa kwebhuleki yasensimini: ebusweni obuhle bomgwaqo, indawo ebanzi futhi engenamuntu, ijubane lifike ngaphezu kwama-60, bese ubeka ibhuleki ekugcineni. Uma isondo likhiyiwe futhi kungekho ukuphazamiseka kokubhuleka, lokhu kungabonisa ukwehluleka kwe-ABS, kuvame ukubangelwa ukulimala kwenzwa ye-ABS.
Sebenzisa i-multimeter ukukala i-voltage/ukumelana kwenzwa ye-ABS: Jikisa isondo ku-1r/s, i-voltage yokukhipha yesondo langaphambili kufanele ibe phakathi kuka-790 no-1140mv, isondo langemuva kufanele libe ngaphezu kuka-650mv. Ngaphezu kwalokho, inani lokumelana lama-ABS sensors ngokuvamile liphakathi kuka-1000 no-1300Ω. Uma la mabanga engahlangatshezwanga, ingabonisa inkinga ngenzwa ye-ABS 34.
Ngamafuphi, uma kunenkinga ngenzwa yesondo langemuva le-ABS, kufanele kuqala uhlole ukuthi kukhona yini umonakalo ongokwenyama, njengokuphuka noma ukuguguleka okusobala. Uma kungekho monakalo obonakalayo ongokwenyama ukuwohloka kokusebenza okubangelwa ukuguguleka noma ezinye izimbangela kungahlolwa kabanzi ngezindlela ezingenhla.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
