Shaqada dareemayaasha garaaca gaariga
Shaqada ugu weyn ee dareemaha garaaca baabuurta waa inuu ogaado dhacdada garaaca ee matoorka, iyo inuu ka hortago garaaca isagoo hagaajinaya Xagasha hore ee dab-shidka, si looga ilaaliyo matoorka waxyeello.
Dareemaha garaaca ayaa gariirka farsamada ee matoorka u beddela calaamado koronto oo loo gudbiyo cutubka xakamaynta elektaroonigga ah (ECU). ECU waxay u habeysaa xagasha hore ee dab-shidka iyadoo loo eegayo calaamadda la helay si looga fogaado dhacdada joogtada ah ee qaraxyada. Dareemaha garaaca badanaa waxay isticmaalaan tignoolajiyada dhoobada piezoelectric. Marka matoorku ruxo, dhoobada waa la cadaadiyaa oo way qalloocdaa si loo soo saaro calaamad koronto, taas oo loo gudbiyo ECU iyada oo loo marayo silig gaashaan ah si loo farsameeyo.
Mabda'a shaqada ee dareemaha garaaca wuxuu ku salaysan yahay saamaynta piezoelectric, marka matoorku garaaco, dhoobada piezoelectric ee ku jirta dareemaha ayaa la cadaadiyaa, taasoo soo saarta calaamad koronto. Calaamadahan waxaa loo diraa ECU, kaas oo hagaajiya xagasha hore ee dab-shidka iyadoo lagu saleynayo xogta la keydiyay si looga hortago garaaca. Intaa waxaa dheer, dareemayaasha garaaca waxay dareemi karaan xawaaraha iyo booska matoorka, iyagoo bixinaya macluumaad badan si ay gacan uga geystaan hagaajinta waxqabadka matoorka.
Dareemaha garaaca waxaa badanaa lagu rakibaa meel gaar ah oo ku taal baloogga matoorka, sida inta u dhaxaysa 2 iyo 3 dhululubo ee mashiinka afar dhululubo ama inta u dhaxaysa dhululubo 1 iyo 2 iyo dhululubo 3 ama 4 ah. Meesha uu ku xiran yahay waxay hubineysaa qabashada xasaasiga ah ee gariirka iyo garaaca yar yar ee matoorka.
Haddii dareemaha garaaca uu fashilmo, inkastoo uusan sababi doonin in matoorku uu shido, waxay sababi doontaa dhibaatooyin sida gariirka matoorka, luminta korontada, hoos u dhaca dhaqaalaha shidaalka, iyo nalalka cilladaysan. Sidaa darteed, shaqada saxda ah ee dareemaha garaaca ayaa muhiim u ah waxqabadka matoorka.
Dareemaha garaaca baabuurta waa aalad lagu rakibay baloogga matoorka, oo inta badan loo isticmaalo in lagu ogaado garaaca matoorka. Waxaa jira noocyo badan oo dareemayaal garaaca ah, kuwaas oo ugu badan oo ay ku jiraan magnetostrictive iyo piezoelectric ceramic.
Nooca iyo qaab-dhismeedka dareemaha garaaca
Magnetostrictive : wuxuu ka kooban yahay xudunta birlabta, birlabta joogtada ah iyo gariiradda soo-kicinta. Marka matoorku gariiro, xudunta birlabta ayaa isbeddela, taasoo keenta isbeddel ku yimaada qulqulka birlabta ee gariiradda soo-kicinta, taasoo keenta xoog koronto oo la kiciyo .
Dhoobada piezoelectric : Marka matoorku ruxo, gudaha dhoobada ayaa la cadaadiyaa si loo soo saaro calaamad koronto. Maadaama calaamaddu daciif tahay, fiilada isku xirka waxaa badanaa lagu duubaa silig gaashaanan.
resonance piezoelectric : oo lagu rakibay qaybta sare ee jirka matoorka, isticmaalka saamaynta piezoelectric si loogu beddelo gariirka farsamada calaamadaha korantada. Marka soo noqnoqoshada gariirka garaaca uu la jaanqaado soo noqnoqoshada dabiiciga ah ee dareemaha, ifafaale resonance ayaa dhici doona, danabka calaamadda garaaca sarena waxaa loo soo saari doonaa ECU, taasoo ECU ay hagaajin doonto waqtiga shidista si looga fogaado garaaca .
Sida dareemaha garaaca u shaqeeyo
Dareemaha garaaca ayaa dareema gariirka iyo dhawaqa matoorka wuxuuna u beddelaa calaamado koronto oo loo diro cutubka xakamaynta matoorka (ECU). ECU wuxuu hagaajiyaa xagasha hore ee shidista iyadoo loo eegayo calaamadda la helay si looga hortago in qarax dhaco. Mabda'a shaqada gaarka ah waa sidan soo socota:
Magnetostriktiv : gariirka matoorku wuxuu sababaa in xudunta birlabtu ay wareegto, taasoo beddesha qulqulka birlabka ee gariiradda induction, taasoo keenta xoog koronto oo la kiciyo .
Dhoobada piezoelectric : marka matoorku ruxo, dhoobada piezoelectric waa la cadaadiyaa si loo soo saaro calaamad koronto, ECU waxay hagaajisaa waqtiga shidista sida ku cad calaamadda.
Nooca falcelinta piezoelectric : marka soo noqnoqoshada gariirka garaaca uu la jaanqaado soo noqnoqoshada dabiiciga ah ee dareemaha, waxaa dhacda dhacdo resonance ah, danab sare oo calaamad garaaca ah ayaa loo soo saaraa ECU.
Doorka dareemayaasha garaaca ee baabuurta
Shaqada ugu weyn ee dareemaha garaaca waa inuu cabbiro heerka gariirka ee matoorka. Marka matoorku soo saaro garaac, calaamadda korontada waxaa loo gudbiyaa ECU, ECU-na waxay si waafaqsan u hagaajisaa xagasha hore ee dab-shidka si looga hortago garaac dheeraad ah. Garaacu wuxuu sababi karaa dhaawac matoorka, sidaa darteed dareemayaasha garaaca ayaa door muhiim ah ka ciyaara ilaalinta matoorka .
