Umugqa wesenzwa ye-ABS engaphambili
Inzwa ye-abs isetshenziswa ku-ABS (Anti-lock Braking System) yemoto. Iningi lesistimu ye-ABS liqashwa yinzwa yokungenisa ukuze iqaphe isivinini semoto. Inzwa ye-abs ikhipha isethi yokunemba. Imvamisa kanye nobukhulu besiginali yamanje eshintshashintshayo ye-sinusoidal kuhlobene nesivinini sesondo. Isignali yokukhipha idluliselwa kuyunithi yokulawula kagesi ye-ABS (ECU) ukuze kuqashwe isivinini sesondo ngesikhathi sangempela.
izinhlobo eziyinhloko
1. Inzwa yesivinini samasondo aqondile
Inzwa yesivinini samasondo eqondile yakhiwe kakhulu yimagnethi ehlala njalo, umgodi wepole, ikhoyili yokungenisa kanye negiya lendandatho. Lapho igiya lendandatho lijikeleza, iziqongo zamazinyo kanye nama-backlashes abhekene ne-polar axis ngokushintshana. Ngesikhathi sokujikeleza kwegiya lendandatho, i-magnetic flux ngaphakathi kwekhoyili yokungenisa iyashintshana ukuze ikhiqize amandla e-electromotive ashukunyiswayo, futhi lesi siginali singena kuyunithi yokulawula kagesi ye-ABS ngekhebula ekugcineni kwekhoyili yokungenisa. Lapho ijubane legiya lendandatho lishintsha, imvamisa yamandla e-electromotive ashukunyiswayo nayo iyashintsha.
2. Inzwa yesivinini sesondo eliyindandatho
Inzwa yesivinini samasondo ajikelezayo yakhiwe kakhulu yimagnethi ehlala njalo, ikhoyili yokungenisa kanye negiya lendandatho. Imagnethi ehlala njalo yakhiwe ngamabhangqa amaningana ezigxobo zikagesi. Ngesikhathi sokujikeleza kwegiya lendandatho, i-magnetic flux ngaphakathi kwekhoyili yokungenisa iyashintsha ngokushintshana ukuze ikhiqize amandla e-electromotive ashukunyiswayo. Lesi siginali sifakwa kuyunithi yokulawula kagesi ye-ABS ngekhebula ekugcineni kwekhoyili yokungenisa. Lapho ijubane legiya lendandatho lishintsha, imvamisa yamandla e-electromotive ashukunyiswayo nayo iyashintsha.
3. Inzwa yesivinini sesondo lehholo
Uma igiya lisendaweni eboniswe ku-(a), imigqa yamandla kazibuthe edlula ku-Hall element iyahlakazeka, kanti insimu kazibuthe ibuthakathaka; kuyilapho lapho igiya lisendaweni eboniswe ku-(b), imigqa yamandla kazibuthe edlula ku-Hall element igxilile, kanti insimu kazibuthe inamandla kakhulu. Lapho igiya lijikeleza, ubuningi bomsinga kazibuthe odlula ku-Hall element buyashintsha, ngaleyo ndlela kubangele ushintsho ku-Hall voltage, futhi i-Hall element izokhipha i-quasi-sine wave voltage yezinga le-millivolt (mV). Lesi siginali sidinga futhi ukuguqulwa sibe yi-pulse voltage ejwayelekile yi-electronic circuit.
Faka Ukusakazwa Kokuhlela
(1) Izingubo zokufaka indandatho yokunyathela
Igiya lendandatho kanye nendandatho yangaphakathi noma i-mandrel yeyunithi ye-hub kuhambisana nokuphazamiseka. Ngesikhathi senqubo yokuhlanganisa iyunithi ye-hub, igiya lendandatho kanye nendandatho yangaphakathi noma i-mandrel kuhlanganiswa ndawonye ngomshini wokucindezela we-hydraulic;
(2) Faka inzwa
Kunezinhlobo ezimbili zokubambisana phakathi kwenzwa kanye nendandatho yangaphandle yeyunithi yehabhu: ukulingana kokuphazamiseka kanye nokukhiya kwe-nut. Inzwa yesivinini sesondo eliqondile isesimweni sokukhiya kwe-nut, kanti inzwa yesivinini sesondo elijikelezayo isebenzisa ukulingana kokuphazamiseka;
Ibanga phakathi kobuso bangaphakathi bemagnethi ehlala njalo kanye nobuso bezinyo begiya lendandatho: 0.5±0.15mm (ikakhulukazi kuqinisekiswa ngokulawula ububanzi bangaphandle begiya lendandatho, ububanzi bangaphakathi benzwa kanye nokugxila kwayo)
(3) Hlola i-voltage Sebenzisa i-voltage yokukhipha yobungcweti kanye ne-waveform eyenziwe ngokwakho ngesivinini esithile, bese uhlola ukuthi ikhona yini i-short circuit ye-linear sensor;
Isivinini: 900rpm
Isidingo se-voltage: 5. 3～7. 9v
Izidingo ze-Waveform: igagasi le-sine elizinzile
ukutholwa kwe-voltage
Ukutholwa kwe-voltage yokukhipha
Izinto zokuhlola:
1. I-voltage yokuphuma: 650 ～850mv (1 20rpm)
2. Ifomu lokuphuma kwegagasi: igagasi le-sine elizinzile
Okwesibili, ukuhlolwa kokuqina kokushisa okuphansi kwenzwa ye-abs
Gcina inzwa ku-40°C amahora angama-24 ukuze uhlole ukuthi inzwa yesisu isakwazi yini ukuhlangabezana nezidingo zokusebenza kagesi kanye nokuvala ukuze isetshenziswe ngendlela evamile.
