Yintoni i-Rear ABS Sensor? Zeziphi iintlobo ezikhoyo kwaye zifakelwa njani?
I-abs sensor isetyenziswa kwi-ABS yesithuthi (iNkqubo yokuQoqa iBraking). Kwinkqubo ye-ABS, isantya sijongwa yi-inductive sensor. I-abs sensor ikhupha iseti yemiqondiso yombane ye-AC e-quasi-sinusoidal ngesenzo seringi yegiya ejikeleza ngokulinganayo nevili, kwaye ubuninzi bayo kunye nobukhulu bayo bunxulumene nesantya sevili. Isignali yokuphuma idluliselwa kwiyunithi yolawulo lwe-elektroniki ye-ABS (ECU) ukuze kujongwe isantya sevili ngexesha langempela.
1, inzwa yesantya sevili elithe tye
I-sensor yesantya sevili elinomgca yenziwe ikakhulu yimagnethi esisigxina, i-pole axis, i-induction coil kunye ne-tooth ring. Xa iringi yegiya ijikeleza, incam yegiya kunye ne-backlash zitshintshana ngokuchasene ne-polar axis. Ngexesha lokujikeleza kweringi yegiya, i-magnetic flux ngaphakathi kwe-induction coil iyatshintshana ukuze ivelise i-induction electromotive force, kwaye esi siginali singena kwiyunithi yolawulo lwe-elektroniki ye-ABS ngentambo ekupheleni kwe-induction coil. Xa isantya seringi yegiya sitshintsha, i-frequency ye-induced electromotive force nayo iyatshintsha.
2, inzwa yesantya sevili elijikelezayo
I-Annular speed sensor yenziwe kakhulu yimagnethi esisigxina, i-induction coil kunye ne-tooth ring. Imagnethi esisigxina yenziwe ngeepali ezininzi ze-magnetic poles. Ngexesha lokujikeleza kweringi yegiya, i-magnetic flux ngaphakathi kwe-induction coil iyatshintsha ngokutshintshana ukuze ivelise i-induction electromotive force. Le signal ifakwa kwiyunithi yolawulo lwe-elektroniki ye-ABS ngentambo ekupheleni kwe-induction coil. Xa isantya seringi yegiya sitshintsha, i-frequency ye-induced electromotive force nayo iyatshintsha.
3, Inzwa yesantya sevili yohlobo lweHolo
Xa igiya ikwindawo eboniswe ku-(a), imigca yemagnethi edlula kwi-Hall element iyasasazeka kwaye i-magnetic field ibuthathaka; Xa igiya ikwindawo eboniswe ku-(b), imigca yemagnethi edlula kwi-Hall element ixinene kwaye i-magnetic field inamandla kakhulu. Xa igiya ijikeleza, uxinano lomgca wamandla wemagnethi odlula kwi-Hall element luyatshintsha, nto leyo ebangela ukuba i-Hall voltage itshintshe, kwaye i-Hall element iya kukhupha i-millivolt (mV) level ye-quasi-sine wave voltage. Esi siginali kufuneka siguqulwe yi-electronic circuit ibe yi-standard pulse voltage.
Faka
(1) Indandatho yegiya yokunyathela
Indandatho yamazinyo kunye nendandatho yangaphakathi okanye i-mandrel yeyunithi ye-hub zihambelana kakuhle. Kwinkqubo yokuhlanganisa iyunithi ye-hub, indandatho yamazinyo kunye nendandatho yangaphakathi okanye i-mandrel zidityaniswe kunye nge-oyile press.
(2) Faka i-sensor
Ukulingana phakathi kwesensor kunye neringi engaphandle yeyunithi yehabhu kukulingana kokuphazamiseka kunye nokutshixwa kwenati. Isensor yesantya sevili elithe tyaba ikakhulu ikwimo yokutshixwa kwenati, kwaye isensor yesantya sevili elithe tyaba isebenzisa ukulingana kokuphazamiseka.
Umgama phakathi komphezulu wangaphakathi wemagnethi esisigxina kunye nomphezulu wezinyo weringi: 0.5 ± 0.15 mm (ngokuyintloko ngolawulo lobubanzi bangaphandle beringi, ububanzi bangaphakathi benzwa kunye nobunzulu)
(3) I-voltage yovavanyo isebenzisa i-voltage yokuvelisa yobungcali eyenziwe ngokwayo kunye ne-waveform ngesantya esithile, kwaye i-sensor ethe tye kufuneka ivavanye ukuba ingaba i-short circuit iyasebenza na;
Isantya: 900rpm
Imfuneko yeVoltage: 5.3 ~ 7.9 V
Iimfuno zefomu yamaza: i-sine wave ezinzileyo
I-Zhuo Meng Shanghai Auto Co., Ltd. izimisele ukuthengisa i-MGIinxalenye zeemoto ze-&MAUXS zamkelekile ukuba uzithenge.
