Xariiqda dareemayaasha ABS ee hore
Dareemaha caloosha waxaa loo isticmaalaa ABS (Nidaamka Bireegga Ka-hortagga Qufulka) ee gaariga. Inta badan nidaamka ABS waxaa la socda dareemaha inductive si loola socdo xawaaraha gaariga. Dareemaha caloosha wuxuu soo saaraa tiro sax ah. Soo noqnoqoshada iyo baaxadda calaamadda hadda ee isbeddelka sinusoidal waxay la xiriirtaa xawaaraha giraangiraha. Calaamadda soo baxda waxaa loo gudbiyaa cutubka xakamaynta elektaroonigga ah ee ABS (ECU) si loo xaqiijiyo la socodka waqtiga-dhabta ah ee xawaaraha giraangiraha.
noocyada ugu muhiimsan
1. Dareemaha xawaaraha giraangiraha toosan
Dareemaha xawaaraha giraangiraha toosan wuxuu inta badan ka kooban yahay birlab joogto ah, usha tiirka, gariirad soo-jeedin iyo qalab giraan ah. Marka qalabka giraangiruhu wareego, dusha sare ee ilkaha iyo dib-u-dhaca waxay si is-beddel ah u wajahayaan dhidibka cidhifka. Inta lagu jiro wareegga qalabka giraangiraha, qulqulka birlabta ee ku jira gariiradda soo-jeedinta ayaa si is-beddel ah isu beddela si uu u soo saaro awood koronto oo la kiciyo, calaamaddanna waxaa la geliyaa qaybta xakamaynta elektaroonigga ah ee ABS iyada oo loo marayo fiilada dhammaadka gariiradda soo-jeedinta. Marka xawaaraha qalabka giraangiruhu isbeddelo, inta jeer ee xoogga koronto ee la kiciyo ayaa sidoo kale isbeddela.
2. Dareemaha xawaaraha giraanta
Dareemaha xawaaraha giraangiraha wareegsan wuxuu inta badan ka kooban yahay birlab joogto ah, gariirad soo-jiidasho iyo qalab giraan ah. Birlabka joogtada ah wuxuu ka kooban yahay dhowr lammaane oo birlab ah. Inta lagu jiro wareegga giraangiraha, qulqulka birlabka ee ku jira gariiradda soo-jiidasho ayaa si is beddel ah isu beddela si uu u soo saaro xoog koronto oo soo-jiidasho leh. Calaamaddan waxaa la gelinayaa qaybta xakamaynta elektaroonigga ah ee ABS iyada oo loo marayo fiilada dhammaadka gariiradda soo-jiidasho leh. Marka xawaaraha giraangiruhu isbeddelo, soo noqnoqoshada xoogga koronto ee la soo saaray ayaa sidoo kale isbeddela.
3. Dareemaha xawaaraha giraangiraha hoolka
Marka geerku joogo booska lagu muujiyey (a), khadadka xoogga birlabta ee dhex mara curiyaha Hall-ka ayaa kala firirsan, goobta birlabtana waa mid daciif ah; halka marka geerku joogo booska lagu muujiyey (b), khadadka xoogga birlabta ee dhex mara curiyaha Hall-ka ayaa xoogaysanaya, goobta birlabtana waa mid xooggan. Marka geerku wareego, cufnaanta qulqulka birlabta ee dhex mara curiyaha Hall-ka ayaa isbeddela, taasoo keenta isbeddel ku yimaada danabka Hall-ka, curiyaha Hall-na wuxuu soo saari doonaa danab hirar quasi-sine ah oo ah heerka millivolt (mV). Calaamaddan sidoo kale waxay u baahan tahay in loo beddelo danab garaac caadi ah oo lagu sameeyo wareeg elektaroonig ah.
Ku rakib Tafatir Baahinta
(1) Qalabka shaabadaynta giraanta
Qalabka giraanta iyo giraanta gudaha ama mandrel-ka cutubka xudunta ayaa ku habboon faragelin. Inta lagu jiro habka isu-imaatinka cutubka xudunta, qalabka giraanta iyo giraanta gudaha ama mandrel-ka waxaa isku daraa matoor hawo-mareenka ah;
(2) Ku rakib dareemaha
Waxaa jira laba nooc oo iskaashi ah oo u dhexeeya dareemaha iyo giraanta dibadda ee cutubka xudunta: ku habboonaanta faragelinta iyo qufulka lowska. Dareemaha xawaaraha giraanta toosan wuxuu inta badan ku jiraa qaabka qufulka lowska, dareemaha xawaaraha giraanta wareegsana wuxuu qaataa ku habboonaanta faragelinta;
Masaafada u dhaxaysa dusha sare ee gudaha ee birlabta joogtada ah iyo dusha sare ee ilkaha ee qalabka giraanta: 0.5±0.15mm (inta badan waxaa lagu hubiyaa iyadoo la xakameynayo dhexroorka dibadda ee qalabka giraanta, dhexroorka gudaha ee dareemaha iyo isku-xidhka)
(3) Tijaabi danabka Isticmaal danabka soo saarista xirfadeed iyo qaabka hirarka ee iskiis u sameeyay xawaare gaar ah, oo tijaabi in uu jiro wareeg gaaban oo loogu talagalay dareemaha toosan;
Xawaaraha: 900rpm
Baahida danab: 5. 3~7.9v
Shuruudaha qaab-dhismeedka hirarka: hirarka sine-ka ee deggan
ogaanshaha danab
ogaanshaha danab soo saarka
Shayada tijaabada ah:
1. Danabka soo baxaya: 650~850mv(1 20rpm)
2. Qaab-dhismeedka hirarka soo baxaya: hirarka sine-ka ee deggan
Marka labaad, tijaabada adkeysiga heerkulka hooseeya ee dareemayaasha caloosha
Dareemaha ku hay 40°C muddo 24 saacadood ah si aad u hubiso in dareemaha caloosha uu wali buuxin karo shuruudaha waxqabadka korontada iyo shaabadeynta si caadi ah loogu isticmaalo.
