Inzwa ye-ABS.
I-ABS sensor isetyenziswa kwi-ABS yemoto (i-Anti-lock Braking System). Kwinkqubo ye-ABS, isantya sijongwa yi-inductive sensor. I-abs sensor ikhupha iseti yemiqondiso yombane ye-AC ejikelezayo nge-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.
Ngaba isenzi se-abs esingasemva esaphukileyo sichaphazela ii-4-drive
Ingayiyo
Ukonakala kwe-ABS sensor yangasemva kunokuchaphazela inkqubo yokuqhuba amavili onke, ingakumbi ukuba inkqubo yokuqhuba amavili onke ixhotyiswe nge-differential locking. Oku kungenxa yokuba i-rear wheel sensor idlala indima ebalulekileyo kwinkqubo yokubopha i-anti-lock (ABS), yakuba yonakele, inkqubo ye-ABS isenokungayiqondi ngokuchanekileyo isantya kunye nemeko yevili, nto leyo echaphazela impembelelo yayo yokuqhobosha, kwaye inokukhokelela ekutshixeni ivili ngexesha lokuqhobosha, okwandisa umngcipheko wokuqhuba. Ukongeza, ukuba inkqubo yokuqhuba amavili amane ixhotyiswe ngomsebenzi wokutshixa ohlukeneyo, umonakalo kwi-rear wheel sensor unokubangela ukuba i-differential lock ingasebenzi kakuhle, nto leyo eya kuchaphazela ukusebenza kwenkqubo yokuqhuba amavili amane. Ke ngoko, nangona umonakalo we-rear wheel sensor ungenakuyichaphazela ngqo umsebenzi osisiseko wenkqubo yokuqhuba amavili amane, ukuqinisekisa ukhuseleko lokuqhuba, kucetyiswa ukuba kulungiswe okanye kutshintshwe i-sensor eyonakeleyo ngexesha.
I-ABS wheel sensor isenokungasebenzi ngenxa yokuguguleka.
Ukusilela kwe-sensor ye-ABS kubandakanya isibane se-ABS kwideshibhodi, i-ABS engasebenzi kakuhle, kunye nesibane sokulawula ukutsalwa kwesandi. Oku kusilela kunokubangelwa kukuguga kwe-sensors, ukunqanyulwa, okanye ukubethwa yinkunkuma. Ingakumbi i-sensor ye-ABS yevili elingasemva, ukuba iziqwenga zesinyithi eziveliswa kukugaywa kwediski yebrake kunye ne-brake pad zifunxwa yimagnethi, kunokukhokelela ekubeni umgama phakathi kwe-sensor kunye ne-magnet coil ube mncinci, okanye ude uguge, ekugqibeleni kukhokelele ekonakaleni kwe-sensor.
Ukuze kuchongwe ukuba i-sensor ye-ABS yonakele na, inokubonwa ngezi ndlela zilandelayo:
Funda ikhowudi yempazamo yesixhobo sokuxilongwa kwempazamo: Ukuba kukho ikhowudi yempazamo kwikhompyutha ye-ABS, kwaye isibane sempazamo kwisixhobo sivuliwe, oku kunokubonisa ukuba isensor yonakele.
Uvavanyo lweebhuleki zasentsimini: kwindawo elungileyo yendlela, ebanzi nengenamntu, isantya ukuya kuthi ga kwi-60, uze ubeke ibhuleki esiphelweni. Ukuba ivili litshixiwe kwaye akukho ngxaki yokubhuleka, oku kunokubonisa ukusilela kwe-ABS, kubangelwa kukonakala kwe-sensor ye-ABS.
Sebenzisa i-multimeter ukulinganisa i-voltage/ukuxhathisa kwe-sensor ye-ABS: Jikisa ivili kwi-1r/s, i-voltage yokuphuma kwevili langaphambili kufuneka ibe phakathi kwe-790 kunye ne-1140mv, ivili langasemva kufuneka libe ngaphezulu kwe-650mv. Ukongeza, ixabiso lokuxhathisa le-sensors ze-ABS ngokubanzi liphakathi kwe-1000 kunye ne-1300Ω. Ukuba ezi zigaba azifikelelwa, ingabonisa ingxaki nge-sensor ye-ABS 34.
Ngamafutshane, ukuba kukho ingxaki nge-sensor yevili langasemva le-ABS, kufuneka kuqala ujonge ukuba kukho umonakalo emzimbeni, njengokuqhekeka okanye ukuguguleka okubonakalayo. Ukuba akukho monakalo emzimbeni ocacileyo, ukuguguleka kokusebenza ngenxa yokuguguleka okanye ezinye izizathu kunokuxilongwa ngakumbi ngeendlela ezingasentla.
