Xariiqda dareenka hore ee ABS
Dareemaha abs waxa loo isticmaalaa ABS (Nidaamka Braking Anti-lock) ee gaadhiga. Inta badan nidaamka ABS waxa la socda dareeraha inductive si uu ula socdo xawaaraha gaadhiga. Dareemaha abs-ku waxa uu soo saaraa tiro sax ah Inta jeer ee iyo baaxadda calaamada beddelka ee sinusoidal waxay la xidhiidhaan xawaaraha giraangiraha. Digniinta wax-soo-saarka waxaa loo gudbiyaa qeybta kontoroolka elektiroonigga ah ee ABS (ECU) si loo xaqiijiyo la socodka waqtiga-dhabta ah ee xawaaraha giraangiraha.
noocyada ugu muhiimsan
1. Dareemaha xawaaraha taayirrada toosan
Dareemaha xawaaraha giraangiraha toosan wuxuu inta badan ka kooban yahay magnet joogto ah, shafka tiirka, gariiradda induction iyo giraanta giraanta. Marka giraanta giraantu wareegto, iligga dushooda iyo dib u laabashada waxay la kulmaan dhidibka cirifka si beddel ah. Inta lagu jiro wareegtada giraanta giraanta, qulqulka magnetic ee gudaha gariiradda induction ayaa is beddeleysa si ay u dhaliso xoog koronto oo la kiciyay, calaamadanina waxay gelisaa unugga kantaroolka elektiroonigga ah ee ABS iyada oo loo sii marayo fiilada dhammaadka gariiradda induction. Marka xawaaraha giraanta giraantu is beddesho, inta jeer ee xoogga korantada ee la kiciyay ayaa sidoo kale isbeddela.
2. Dareemaha xawaaraha giraangiraha giraanta
Dareemaha xawaaraha giraangiraha annular wuxuu inta badan ka kooban yahay magnet joogto ah, gariiradda induction iyo giraanta giraanta. Magnet-ka joogtada ahi waxa uu ka kooban yahay dhawr lammaane oo bir birlab ah. Inta lagu jiro wareegtada giraanta giraanta, qulqulka magnetic ee gudaha gariiradda induction ayaa is beddeleysa si uu u dhaliyo xoog koronto oo la kiciyay. Digniintu waxa ay gelisaa unugga kantaroolka elektarooniga ah ee ABS iyada oo loo sii marayo fiilada dhammaadka gariiradda induction. Marka xawaaraha giraanta giraantu is beddesho, inta jeer ee xoogga korantada ee la kiciyay ayaa sidoo kale isbeddela.
3. Dareemaha xawaaraha taayirrada Hall
Marka gearku ku yaal meesha lagu muujiyey (a), xadhkaha xoogga birlabeedka ee dhex mara qaybta Hoolka waa la kala firdhiyaa, goobta magnetic waa mid daciif ah; halka marka gearku uu yaallo meesha lagu muujiyey (b), xadhkaha xoogga magnetic ee dhex mara qaybta Hoolka ayaa xoogaysan, goobta magnetic-ku waa mid xoog badan. Marka gearku wareego, cufnaanta qulqulka magnetic ee dhex mara qaybta Hall-ka ayaa isbeddelaysa, sidaas awgeed isbeddel ku yimaadda tamarta Hall-ka, iyo element Hall-ku waxa uu soo saari doonaa danab mawjad quasi-sine ah oo ah heerka millivolt (mV). Digniintani waxay sidoo kale u baahan tahay in loo beddelo korantada garaaca wadnaha ee caadiga ah iyadoo loo marayo wareegga elektaroonigga ah.
Ku rakib Beddelka Tafatirka
(1) Qalabka giraanta shaabadda
Gear-ga giraanta iyo giraanta gudaha ama mander-ka unugga xuddunta waxay qaataan ku habboonaanta faragelinta. Inta lagu jiro habka isku xirka unugga xuddunta, giraanta giraanta iyo giraanta gudaha ama mandrel ayaa la isku daraa iyada oo la raacayo qalabka korontada;
(2) Ku rakib dareeraha
Waxa jira laba nooc oo wada shaqayneed oo u dhexeeya dareemaha iyo giraanta dibadda ee unugga xuddunta: ku habboonaanta faragelinta iyo xidhitaanka lowska. Dareemka xawaaraha giraangiraha toosan ayaa inta badan qaabaysan qaabka looska, iyo dareemaha xawaaraha giraangiraha ee anular wuxuu qaataa ku haboonaanta faragelinta;
Masaafada u dhaxaysa dusha gudaha ee magnetka joogtada ah iyo dusha iliga ee giraanta giraanta: 0.5 ± 0.15mm (inta badan waxaa lagu hubiyaa iyada oo la xakameynayo dhexroorka dibedda ee giraanta giraanta, dhexroorka gudaha ee dareemayaasha iyo diiradda)
(3) Tijaabi danabka Isticmaal koronto-soo-saarka xirfad-yaqaanka ah ee is-ku-sameeyey iyo qaab mawjada xawaare gaar ah, oo tijaabi haddii uu jiro wareeg gaaban oo loogu talagalay dareemayaasha toosan;
Xawaaraha: 900rpm
Shuruudaha Voltage: 5. 3～7. 9v
Shuruudaha Waveform: Hirarka seeraha oo deggan
ogaanshaha danab
Ogaanshaha danabka soo baxay
Tijaabi walxaha:
1. Korontada soo baxda: 650～850mv(1 20rpm)
2. Qaabka mowjadda wax soo saarka: hirka seefta oo deggan
Marka labaad, tijaabada adkeysiga heerkulka hoose ee abs sensor
Dareemaha ku hay 40°C 24 saacadood si aad u hubiso in dareemaha absku uu wali buuxin karo shuruudaha waxqabadka korantada iyo xidhida isticmaalka caadiga ah
