Duritaanada casriga ah iyo matoorada naaftada ayaa isticmaala nidaamyada xakamaynta leh dareemeyaal badan oo kormeera daraasiin cabbirro ah.Dareemayaasha dhexdooda, meel gaar ah waxaa ku jira dareeme wajiga, ama dareemaha booska camshaft.Ka akhriso shaqooyinka, naqshadaynta iyo hawlgalka dareemahan maqaalka.
Waa maxay dareenka wajiga
Dareemka wajiga (DF) ama camshaft position sensor (DPRV) waa dareemayaasha nidaamka xakamaynta ee gaaska la isku duro iyo matoorada naaftada ee kormeera booska habka qaybinta gaaska.Iyada oo la kaashanayo DF, bilowga wareegga matoorka waxaa lagu go'aamiyaa dhululubada ugu horreysa (marka TDC la gaaro) iyo habka cirbadaha wajiga ah ayaa la hirgeliyaa.Dareemkan waxa uu si shaqaynaya ugu xidhan yahay dareemaha booska crankshaft (DPKV) - nidaamka maaraynta mishiinada elektarooniga ah waxa uu isticmaalaa akhrinta labada dareemayaal, taas oo ku salaysan tan, waxay abuurtaa garaaca garaaca duritaanka shidaalka iyo shididda dhululubo kasta.
DF-yada waxaa loo isticmaalaa kaliya matoorada shidaalka ee leh irbado qaybsan iyo qaar ka mid ah matoorada naaftada.Waxayna u mahad naqaysaa dareemaha in mabda'a aad u fudud ee duritaanka wejiga ah si fudud loo hirgeliyo, taas oo ah, duritaanka shidaalka iyo shidda dhululubo kasta, iyadoo ku xidhan habka hawlgalka engine.Looma baahna DF ee matoorada carburetor-ka, tan iyo isku darka shidaalka-hawada waxaa la siiyaa dhululubada iyada oo loo marayo kala duwanaansho caadi ah, iyo shidda waxaa lagu xakameynayaa iyadoo la isticmaalayo qaybiyaha ama dareeraha booska crankshaft.
DF waxa kale oo loo adeegsadaa matoorada leh nidaamka wakhtiga waalka doorsooma.Xaaladdan oo kale, dareemayaasha kala duwan ayaa loo isticmaalaa kamaradaha kaamirooyinka ee xakameynaya qaadashada iyo qiiqa qiiqa, iyo sidoo kale nidaamyada xakamaynta kakan iyo algorithmskooda hawlgalka.
Naqshadeynta dareemayaasha wajiga
Waqtigan xaadirka ah, DF oo ku saleysan saameynta Hall-ka ayaa la isticmaalaa - dhacdada kala duwanaanshaha suurtagalka ah ee wafer semiconductor kaas oo hadda si toos ah u socdo marka la dhigo goobta magnetic.Dareemayaasha saamaynta hoolka si fudud ayaa loo hirgeliyaa.Waxay ku salaysan tahay wafer afar gees ah ama afargees ah, afar geesood oo xiriiriyayaal ah ayaa ku xiran - laba qalab, oo loogu talagalay bixinta hadda si toos ah, iyo laba wax soo saar, si loo saaro calaamadda.Si loo fududeeyo, nashqadan waxaa lagu sameeyay qaab jajab ah, kaas oo lagu rakibay guryaha dareemayaasha oo ay weheliyaan magnet iyo qaybo kale.
Waxaa jira laba nooc oo naqshadeynta dareemayaasha wajiga:
-Sloted;
- Dhammaad (ul).
Dareemaha dillaacsan
Dareemka dhamaadka
Dareemka wajiga la jeexjeexay wuxuu leeyahay qaab U-qaab ah, qaybtiisa waxaa ku yaal barta tixraaca (calaamadeeyaha) ee kamarada.Jidhka dareemaha wuxuu u qaybsan yahay laba qaybood, mid ka mid ah waxaa jira magnet joogto ah, kan labaadna waxaa jira element xasaasi ah, labada qayboodba waxaa jira koofiyado magnet ah oo qaab gaar ah, kuwaas oo bixiya isbeddel ku yimaada magnetic field inta lagu jiro marinka bartilmaameedka.
Dareemka dhamaadka wuxuu leeyahay qaab cylindrical ah, barta tixraaca camshaft waxay u gudubtaa xagga hore ee dhamaadka.Dareemkan, cunsurka dareenku wuxuu ku yaalaa dhamaadka, korkiisa waa magnet joogto ah iyo koofiyadaha magnetic.
Waa in halkan lagu ogaadaa in dareemaha booska camshaft uu yahay mid isku mid ah, taas oo ah, waxay isku daraysaa qaybta dareenka calaamadaha ee kor lagu sharraxay iyo beddelaha signalka labaad ee kor u qaadaya signalka oo u beddelaya qaab ku habboon habaynta nidaamka xakamaynta elektaroonigga ah.Transducer waxaa sida caadiga ah si toos ah loogu dhisay dareemaha, taas oo si weyn u fududaynaysa rakibidda iyo habaynta nidaamka oo dhan.
Mabda'a Shaqada ee Dareemka Wajiga
Dareemka wajiga waxa lagu lamaanaa saxan master ah oo ku dul rakiban kamaradaSaxankani waxa uu leeyahay barta tixraaca ee hal nakhshad ama mid kale, kaas oo u gudba dareemaha hortiisa ama farqiga u dhexeeya inta lagu jiro hawlgalka mishiinka.Markaad ka gudubto dareemaha hortiisa, barta tixraacku waxay xidhaysaa xadhkaha magnetic ee ka soo baxaya, taas oo horseedaysa isbeddel ku yimaada goobta magnetic ee ka gudbaya walxaha xasaasiga ah.Natiijo ahaan, dareen koronto ayaa ka dhex abuurma dareeraha Hall-ka, kaas oo la xoojiyay oo beddelay beddelaha, oo lagu quudiyay qaybta kontoroolka mishiinnada elektaroonigga ah.
Dareemayaasha la jeexjeexay iyo kuwa dhammaadka ah, saxanadaha master-ka ee nashqadaha kala duwan ayaa loo isticmaalaa.Isku-dubbarididda dareemayaasha godadsan, saxan leh farqiga hawo ayaa shaqeeya - garaaca garaaca wadnaha ayaa la sameeyaa marka farqigaan dhaafo.Marka lagu xidho dareeraha dhamaadka, saxan ilko leh ama bar-tilmaameedyo gaagaaban ayaa shaqeeya - dareenka xakamaynta ayaa la sameeyaa marka bartilmaameedku dhaafo.
