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.
Faka
(1) Iringi yesitampu
Umsesane izinyo kunye ring yangaphakathi okanye mandrel hub iyunithi amkele ukuphazanyiswa fit. Kwinkqubo yokuhlanganiswa kweyunithi ye-hub, ikhonkco lezinyo kunye nendandatho yangaphakathi okanye i-mandrel idityaniswe kunye ne-oyile.
(2) Faka isivamvo
Ukulingana phakathi kwenzwa kunye neringi yangaphandle yeyunithi ye-hub yi-interference fit kunye ne-nut lock. Isivamvo sesantya sesondo esisemgceni siluhlobo lwesitshixo se-nut, kwaye isantya sevili leringi samkela uphazamiseko olufanelekileyo.
Umgama phakathi kwendawo yangaphakathi yemagnethi esisigxina kunye nomgangatho wezinyo lwendandatho: 0.5 ± 0.15 mm (ikakhulukazi ngolawulo lwe-diameter yangaphandle yeringi, i-diameter yangaphakathi ye-sensor kunye ne-concentricity)
(3) Amandla ombane ovavanyo asebenzisa ivoltheji yemveliso eyenziwe ngokwayo kunye ne-waveform ngesantya esithile, kwaye isivamvo somgca kufuneka sivavanye ukuba isekethe emfutshane;
Isantya: 900rpm
Imfuneko yombane: 5.3 ~ 7.9 V
Iimfuno ze-Waveform: i-sine wave ezinzileyo
Ukufunyanwa kwamandla ombane
Ukufunyanwa kombane ophumayo
Izinto zokuhlola:
1, imveliso yombane: 650 ~ 850mv (1 20rpm)
I-2, i-wave waveform: i-sine wave ezinzileyo
Okwesibini, uvavanyo lwe-abs sensor yobushushu obuphantsi
Gcina i-sensor kwi-40 ° C kwiiyure ezingama-24 ukuvavanya ukuba i-abs sensor isenakho ukuhlangabezana neemfuno zombane kunye nokutywinwa kokusetyenziswa okuqhelekileyo.
Kutheni le nto i-abs sensor ilula kakhulu ukuphuka
Izizathu zokuba i-sensor ye-ABS ilula ukuyonakalisa ikakhulu ibandakanya inxalenye ye-induction ihlanganiswe, umgca ukhululekile kunye nomgangatho wenzwa ngokwayo. Iinkcukacha zezi zilandelayo:
Inxalenye yokuva igutyungelwe: xa i-sensor ye-ABS igutyungelwe bumdaka, uthuli okanye ezinye imizimba yangaphandle, iya kuphazamisa ukuphuma kwesignali ye-sensor, okubangela ukuba ikhomputha ingakwazi ukugweba ngokuchanekileyo isantya. kuchaphazela ukusebenza okuqhelekileyo kwenkqubo yebrake.
Umgca okhululekileyo: Uxhumo lomgca we-sensor alunamandla okanye umdibaniso ukhululekile, okuya kubangela ukuhanjiswa kwesignali embi, okubangelwa iimpazamo zenkqubo. Impazamo eqhelekileyo kukuba isibane sempazamo sivuliwe.
Umgangatho we-sensor ngokwayo: ukuba umgangatho we-sensor ye-ABS umpofu, unokuchaphazela ukuzinza kwesignali yayo yokuphuma, kwaye emva koko kuchaphazela uvakalelo lwenkqubo ye-ABS kunye nokhuseleko lokuqhuba.
Ezi zinto zinokubangela ukuba i-sensor ye-ABS yonakaliswe ngokulula, ngoko ngexesha lokusetyenziswa kunye nokugcinwa, ingqalelo kufuneka ihlawulwe ekugcineni i-sensor icocekile kwaye ihlolisise imeko yokudibanisa yomgca ukuqinisekisa ukhuseleko lokuqhuba.
