Iyini i-Rear ABS Sensor? Yiziphi izinhlobo ezikhona futhi zifakwa kanjani?
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.
Faka
(1) Indandatho yegiya lokunyathela
Indandatho yamazinyo kanye nendandatho yangaphakathi noma i-mandrel yeyunithi ye-hub kuhambisana nokuphazamiseka. Enqubweni yokuhlanganiswa kweyunithi ye-hub, indandatho yamazinyo kanye nendandatho yangaphakathi noma i-mandrel kuhlanganiswa ndawonye ngomshini wokunyathelisa uwoyela.
(2) Faka inzwa
Ukulingana phakathi kwenzwa nendandatho yangaphandle yeyunithi yehabhu kuhambisana nokuphazamiseka kanye nokukhiya kwe-nut. Inzwa yesivinini sesondo eliqondile ngokuyinhloko iwuhlobo lokukhiya kwe-nut, kanti inzwa yesivinini sesondo eliyindandatho isebenzisa ukulingana kokuphazamiseka.
Ibanga phakathi kobuso bangaphakathi bemagnethi ehlala njalo kanye nobuso bezinyo bendandatho: 0.5 ± 0.15 mm (ikakhulukazi ngokulawula ububanzi bangaphandle bendandatho, ububanzi bangaphakathi benzwa kanye nokugxila)
(3) I-voltage yokuhlola isebenzisa i-voltage yokuphuma yobungcweti eyenziwe ngokwayo kanye ne-waveform ngesivinini esithile, futhi inzwa eqondile kufanele futhi ihlole ukuthi ngabe i-short circuit iyasebenza yini;
Isivinini: 900rpm
Imfuneko ye-voltage: 5.3 ~ 7.9 V
Izidingo ze-Waveform: igagasi le-sine elizinzile
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni i-MGIzingxenye zezimoto ze-&MAUXS zamukelekile ukuzithenga.
