Inzwa ye-ABS.
Inzwa ye-Abs isetyenziswe kwi-ABS yemoto (i-Anti-lock Braking System). Kwinkqubo ye-ABS, isantya sijongwa yi-sensor inductive. I-abs sensor ikhupha isethi yeempawu zombane ze-quasi-sinusoidal AC ngokusebenzisa intshukumo yeringi yegiya ejikeleza ngolungelelwaniso kunye nevili, kunye ne-frequency yayo kunye ne-amplitude ihambelana nesantya sevili. Isiginali yemveliso igqithiselwa kwiyunithi yolawulo lwe-elektroniki ye-ABS (ECU) ukuqonda ukubekwa esweni kwexesha lokwenyani lesantya sevili.
1, isivamvo sesantya sevili esinomgca
Isivamvo sesantya sevili somgca siqulunqwe ikakhulu yimagnethi esisigxina, i-axis yepali, icoil yokungeniswa kunye neringi yezinyo. Xa umsesane wegiya ujikeleza, incam yegiya kunye ne-backlash echasene ne-axis yepolar. Ngexesha lokujikeleza kwendandatho yegiya, i-flux yamagnetic ngaphakathi kwekhoyili ye-induction iyatshintsha ngokuhlukileyo ukuvelisa amandla e-electromotive induction, kwaye lo mqondiso ufakwa kwiyunithi yokulawula i-elektroniki ye-ABS ngentambo ekupheleni kwekhoyili ye-induction. Xa isantya seringi yegiya sitshintsha, ukuphindaphindwa kwamandla e-electromotive okwenziwayo nawo ayatshintsha.
2, isivamvo sesantya sevili leringi
Isivamvo sesantya sevili seAnnular ikakhulu siqulunqwe yimagnethi esisigxina, icoil yokwenziwa kunye neringi yezinyo. Umazibuthe osisigxina wenziwa ziiperi ezininzi zeepali zemagnethi. Ngexesha lokujikeleza kweringi yegiya, i-flux yamagnetic ngaphakathi kwekhoyili ye-induction iyatshintsha ngenye indlela ukuvelisa amandla e-electromotive induction. Lo mqondiso ufaka igalelo kwiyunithi yokulawula i-elektroniki ye-ABS ngekhebula ekupheleni kwe-coil induction. Xa isantya seringi yegiya sitshintsha, ukuphindaphindwa kwamandla e-electromotive okwenziwayo nawo ayatshintsha.
3, Iholo uhlobo ivili isantya isivamvo
Xa igiya ikwindawo eboniswe ku-(a), imigca yemagnethi edlula kwindawo yeHolo iyahlakazwa kwaye imagnethi ibuthathaka; Xa igiya ikwindawo eboniswe ku-(b), imigca yemagnethi edlula kwindawo yeHolo igxininiswe kwaye imagnethi yomelele. Xa igiya ijikeleza, ukuxinana komgca wemagnethi wamandla odlula kwindawo yeHolo iyatshintsha, nto leyo ebangela ukuba umbane weHolo utshintshe, kwaye into yeHolo iya kukhupha inqanaba le-millivolt (mV) le-quasi-sine wave voltage. Lo mqondiso kwakhona kufuneka uguqulwe yisekethe ye-elektroniki ibe ngumbane oqhelekileyo we-pulse.
Ngaba i-abs sensor yangasemva eyaphukileyo ichaphazela i-4-drive
Ingayiyo
Umonakalo kwi-sensor ye-ABS yangasemva inokuchaphazela inkqubo ye-wheel drive yonke, ngakumbi ukuba i-all-wheel drive system ixhotyiswe ngokutshixa ngokwahlukileyo. Oku kungenxa yokuba isivamvo sevili langasemva sidlala indima ebalulekileyo kwinkqubo yokunqanda ukutshixa (ABS), xa yonakele, inkqubo ye-ABS isenokungasiboni ngokuchanekileyo isantya kunye nobume bevili, nto leyo echaphazela isiphumo sayo sokuqhawuka, kwaye inokukhokelela ekubeni ibambe. kwisitshixo sevili ngexesha lokuqhobosha, kwandisa umngcipheko wokuqhuba. Ukongeza, ukuba inkqubo yokuqhuba amavili amane ixhotyiswe ngomsebenzi wokutshixa umahluko, umonakalo kwinzwa yesondo yangasemva inokubangela ukuba isitshixo sokwahlukana singasebenzi kakuhle, nto leyo eya kuchaphazela ukusebenza kwenkqubo yokuqhuba ngamavili amane. Ngoko ke, nangona umonakalo wenzwa yesondo yangasemva awunakuchaphazela ngokuthe ngqo umsebenzi osisiseko wenkqubo yokuqhuba amavili amane, ukwenzela ukuba kuqinisekiswe ukhuseleko lokuqhuba, kuyacetyiswa ukuba ulungise okanye utshintshe inzwa eyonakalisiweyo ngexesha.
Inzwa yevili yangasemva ye-ABS inokusilela ngenxa yokunxiba. ...
Ukungaphumeleli kwe-sensor ye-ABS kubandakanya ukukhanya kwe-ABS kwideshibhodi, i-ABS engasebenzi kakuhle, kunye nokulawula ukukhanya kokukhanya. Oku kusilela kunokubangelwa kukuphelelwa ngamandla, ukuqhawuka konxibelelwano, okanye ukubethwa bubutyobo. Ngokukodwa inzwa yesondo yangasemva ye-ABS, ukuba iintsimbi zentsimbi ezenziwe kukusila idiski yebhuleki kunye nephedi yebhuleki zibhengezwa yimagnethi, kunokukhokelela kumgama phakathi kwenzwa kunye nekhoyili yemagnethi ibe ncinci, okanye inxibe. , ekugqibeleni kukhokelela kumonakalo wenzwa. ...
Ukuqinisekisa ukuba i-sensor ye-ABS yonakele, inokubonwa ngezi ndlela zilandelayo:
Funda ikhowudi yempazamo yesixhobo sokuxilongwa: Ukuba kukho ikhowudi yempazamo kwikhompyuter ye-ABS, kwaye ukukhanya kwempazamo kwisixhobo kuvuliwe, oku kungabonisa ukuba inzwa yonakele. ...
Uvavanyo lwebrake ebaleni: kwindlela elungileyo, indawo ebanzi nengenamntu, isantya ukuya kuthi ga ngaphezulu kwama-60, emva koko ubeke ibhuleki kude kube sekupheleni. Ukuba ivili litshixiwe kwaye akukho kuphazamiseka kwe-braking, oku kungabonisa ukusilela kwe-ABS, kudla ngokubangelwa ngumonakalo kwinzwa ye-ABS. ...
Sebenzisa i-multimeter ukulinganisa i-voltage / ukuchasana kwe-sensor ye-ABS: Jika isondo kwi-1r / s, i-voltage ephumayo yevili langaphambili kufuneka ibe phakathi kwe-790 kunye ne-1140mv, isondo elingasemva kufuneka libe phezulu kune-650mv. Ukongeza, ixabiso lokumelana ne-ABS sensors liphakathi kwe-1000 kunye ne-1300Ω. Ukuba olu luhlu aluhlangabezwanga, kunokubonisa ingxaki ngesixhobo soluvo se-ABS 34.
Isishwankathelo, ukuba kukho ingxaki nge-ABS yoluvo lwamavili angasemva, kufuneka kuqala kujongwe ukuba kukho umonakalo obonakalayo, njengokuqhekeka okanye ukunxitywa okucacileyo. Ukuba akukho monakalo ucacileyo wokuthotywa kwentsebenzo ngenxa yokunxiba okanye ezinye izizathu zinokufunyaniswa ngakumbi ngezi ndlela zingasentla. ...
