Waa maxay dareemaha crankshaft-ka baabuurta?
Dareemaha crankshaft (oo sidoo kale loo yaqaan dareemaha booska crankshaft) waa qayb muhiim ah oo ka mid ah nidaamka xakamaynta elektaroonigga ah ee matoorka. Inta badan waxaa loo isticmaalaa in lagu ogaado booska wareegga (xagasha) ee crankshaft iyo xawaaraha matoorka, ka dibna macluumaadkan waqtiga dhabta ah loogu gudbiyo cutubka xakamaynta matoorka (ECU) si sax ah loogu xakameeyo waqtiga shidista, waqtiga duritaanka shidaalka, iyo taxanaha shidista.
Hawlaha ugu muhiimsan
Go'aami xagasha crankshaft: Go'aami booska saxda ah ee piston-ka ee ku jira dhululubada (sida bartamaha sare ee dhintay).
La soco xawaaraha matoorka: Xisaabi RPM (kacaankii daqiiqaddii) iyadoo loo eegayo inta jeer ee wareegga crankshaft-ka.
La shaqee dareemaha booska camshaft: Wadajir, aqoonso xaaladda shaqada ee dhululubo kasta (sida riixitaanka), oo ku guuleysta duritaanka iyo shidista shidaalka ee isku xiga.
Noocyada caadiga ah iyo mabaadi'da shaqada
Nooca soo-kicinta birlabta-korontada (nooca garaaca birlabta)
Waxay ka kooban tahay birlab joogto ah, gariirad soo-saarid ah, iyo saxan calaamadeed oo leh ilko/gees.
Marka shafka crankshaft uu wareego, saxanka calaamaduhu wuxuu beddelaa goobta birlabta, isagoo soo saaraya calaamad danab beddelan oo ku jirta gariiradda.
Qaab-dhismeedku waa mid fudud oo la isku halleyn karo, si weyn ayaa loogu isticmaalaa moodooyinka hore iyo qaar ka mid ah gawaarida casriga ah.
Nooca saameynta hoolka
Wuxuu adeegsadaa curiye Hall ah si uu u dareemo isbeddellada ku yimaada goobta birlabta wuxuuna soo saaraa calaamad garaaca hirarka laba jibbaaran.
Waxay u baahan tahay koronto 5V ah oo dibadda ah waxayna leedahay awood xooggan oo ka hortagga faragelinta iyo saxnaan sare.
Waxaa badanaa laga helaa noocyada sida General Motors (GM), Chrysler, iwm.
Nooca sawir-qaadista
Waxay ka kooban tahay LED, photodiode, iyo saxan calaamadeed oo leh godad iftiin leh.
Is-beddelka iftiinka/hadhka ayaa soo saara calaamadaha garaaca wadnaha, kuwaas oo loo isticmaalay Nissan iyo moodooyinka kale.
Maadaama ay u nugul tahay saliidda iyo boodhka, waxaa si weyn looga saaray.
Goobta rakibidda
Dhammaadka hore ee shafka crankshaft (meel u dhow suunka pulley-ga)
Dhamaadka dambe ee shafka crankshaft (oo u dhow giraangiraha duulaya ama guriga gudbinta)
Bartamaha shafka crankshaft
Qaybiyaha (noocyadii hore)
Muujinta cilladaha caadiga ah
Matoorku ma bilaaban karo
Xasillooni la'aan shaqo la'aan ah, dardargelin daciif ah
Nalalka cilladda matoorka ayaa shidan
Koodhadhka cilladaha ee la keydiyay (sida P0335, P0336, iwm.)
Habka ogaanshaha (tusaale: nooca birlabta-korontada)
Hubinta iska caabbinta: Iska caabbinta gariiradda badanaa waa 125–250Ω (iyadoo ku xiran nooca).
Hubinta danabka calaamadda: Markaad shideyso matoorka, isticmaal multimeter si aad u cabbirto terminal-ka soo baxaya, kaas oo leh danabka garaaca AC ee 0.2–2V.
Hubinta farqiga: Farqiga u dhexeeya saxanka calaamadda iyo madaxa birlabta dareemaha guud ahaan waa 0.2–0.4mm.
Haddii dareemaha uu dhaawacmo, ECU ma heli doonto macluumaadka muhiimka ah ee waqtiga, taasoo keenta in nidaamka shidaalka lagu shubo iyo dab-shidku uu xumaado, gaariguna ma shaqeyn doono.
Dareemaha crankshaft (oo sidoo kale loo yaqaan dareemaha booska crankshaft) waa qayb muhiim ah oo ka mid ah nidaamka xakamaynta elektaroonigga ah ee matoorka. Shaqadeeda ugu weyn waa inay ogaato xagasha crankshaft, xawaaraha matoorka, iyo booska dhexe ee ugu sarreeya ee bistoolada, ka dibna macluumaadkan u gudbiso qaab calaamad koronto cutubka xakamaynta matoorka (ECU) si loo xakameeyo waqtiga dab-shidka iyo waqtiga duritaanka shidaalka.
Shaqada asaasiga ah
Go'aami booska shafka crankshaft: Aqoonso xagasha shafka crankshaft ee hadda jirta.
Cabbirka xawaaraha matoorka: Xisaabi xawaaraha (RPM) iyadoo loo eegayo tirada garaaca halbeeg kasta.
Aqoonso xarunta ugu sarreysa ee bistooladda: Bixi tixraac ku saabsan shidista iyo duritaanka shidaalka ee silinda kasta.
La shaqee dareemaha booska camshaft: Wadajir, go'aamiya dhululubada ku taal dhammaadka riixitaanka, oo ku guuleysta dab-shidid isku xigxiga iyo duritaanka shidaalka.
Mabda'a shaqada (nooca kala soocidda)
Dareemaha crankshaft wuxuu leeyahay saddex nooc oo waaweyn, mabaadi'dooda shaqaduna waa sidan soo socota:
Nooca soo-kicinta birlabta-korontada (nooca garaaca birlabta)
Waxay ka kooban tahay birlab joogto ah, gariirad soo-saarid ah, iyo saxan calaamadeed oo leh ilko/gees.
Marka shafka crankshaft uu wareego, saxanka calaamaduhu wuxuu beddelaa goobta birlabta, taasoo keenta isbeddel ku yimaada goobta birlabta, waxayna soo saartaa xoog koronto oo beddelan (calaamadda hirarka sine) ee gariiradda.
ECU-gu wuxuu calaamaddan u beddelaa garaacisyo wuxuuna xisaabiyaa xawaaraha iyo booska.
Tusaale ahaan: Moodalkii hore ee Nissan iyo Toyota waxay isticmaaleen habkan, saxanka calaamaduhuna badanaa wuxuu lahaa ilko maqan oo loogu talagalay isku-dubaridka.
Nooca saameynta hoolka Qaybta hoolka waxaa loo isticmaalaa in lagu dareemo isbeddellada ku yimaada goobta birlabta.
Qalabka riixa (oo leh daabyo iyo daloolo) ayaa la kiciyaa si uu ugu wareego shaftka crankshaft. Marka qaybta la jaanqaado curiyaha Hall, goobta birlabta ayaa dhex marta oo soo saarta garaac heer sare ah; marka daabku xannibo, goobta birlabta ayaa dhaafta oo soo saarta heer hoose.
Wax soo saarku waa calaamad hirar laba jibbaaran ah, taas oo u baahan koronto 5V oo dibadda ah waxayna leedahay awood xooggan oo ka hortagga faragelinta.
Aragti ahaan
Waxay ka kooban tahay isha iftiinka LED, photodiode, iyo saxan calaamadeed oo leh god iftiin leh.
Marka saxanka calaamaduhu wareego, godka iftiinku wuxuu si kale u oggolaanayaa in iftiinku gudbo oo uu xannibo, taasoo keenta in photodiode-ku uu soo saaro danab garaaca wadnaha ah.
Waxay soo saari kartaa calaamad xagal shaft ah oo sax ah oo 1° ah, laakiin waxay u nugul tahay wasakhaynta saliidda iyo boodhka, waxaana badanaa lagu arkaa qaab-dhismeedka qaybiyaha duugga ah.
Calaamadaha cilladaha caadiga ah
Matoorku ma bilaabi karo ama kuma bilaabi karo dhib la'aan
Awood la'aan, gariir, iyo hakad
Iftiinka cilladdu wuu shidan yahay (sida P0335, P0336, iwm., koodhadhka cilladaha la xiriira ee dareemayaasha booska crankshaft)
Sababaha caadiga ah: fiilooyinka duugoobay, dareemayaasha wasakhaysan, nadiifinta aan habboonayn (sida nadiifinta nooca birlabta-korontada waa inay noqotaa 0.2-0.4mm)
Goobta rakibidda
Dhammaadka hore ee crankshaft (meel u dhow pulley-ga)
Guryaha Flywheel ama clutch-ka
Dhammaadka hore ee shafka camshaft
Gudaha qaybiyaha (noocyadii hore)
Moodooyinka ugu caansan ee hadda jira waxay isticmaalaan dareemayaal birlab-koronto ama nooca Hall-ka, maadaama qaab-dhismeedkoodu yahay mid la isku halleyn karo oo la qabsan karo. Nooca indhaha si dhif ah ayaa loogu isticmaalaa matoorada casriga ah sababtoo ah xasaasiyaddiisa deegaanka.
