Doorka dareemaha booska kamaradda.
Doorka dareemaha booska camshaft-ka baabuurta:
1, dareemaha booska camshaft waa inuu ururiyo calaamadda xagasha firfircoon ee camshaft, oo uu geliyo cutubka xakamaynta elektaroonigga ah (ECU), si loo go'aamiyo wakhtiga shidista iyo wakhtiga duritaanka, si loo helo qaadashada iyo qiiqa;
2, si loo fuliyo xakamaynta duritaanka shidaalka ee isku xiga, xakamaynta waqtiga shidista iyo xakamaynta dab-shidka. Intaa waxaa dheer, calaamadda booska shafka ayaa loo isticmaalaa in lagu aqoonsado daqiiqadda ugu horreysa ee shidista marka matoorku bilaabo. Sababtoo ah dareemaha booska shafka ayaa aqoonsan kara piston-ka silinda ee ku dhow inuu gaaro TDC, waxaa loo yaqaan dareemaha aqoonsiga silinda;
3, qaab-dhismeedka iyo mabda'a shaqada ee dareemaha booska camshaft iyo dareemaha booska crankshaft asal ahaan waa isku mid, badanaana waa la isku rakibaa, laakiin booska rakibidda ee nooc kasta waa ka duwan yahay, laakiin waa in lagu rakibaa booska xiriirka gudbinta saxda ah ee crankshaft, sida crankshaft, camshaft, flywheel ama qaybiyaha;
4, si fudud u isticmaal nidaamka dareemayaasha crankshaft-ka ee ECU wuxuu leeyahay hab gaar ah oo lagu kala saaro dab-shidka, si loo kala saaro taxanaha dab-shidka dhululubada, way ka duwan tahay habka loo isticmaalo laba dareemayaal taas oo ah, barta caanka ah waa "tirinta", crankshaft-ku wuxuu ku shaqeeyaa "1-3-4-2" tiro go'an oo wareegyo ah. Markaa barnaamijku wuxuu "tirin karaa" dhululubada rasaasta ee kala duwan ee ku yaal isla xagasha crankshaft-ka, markaa hal dareemayaal ayaa ku filan.
Dareemaha booska Camshaft waxaa sidoo kale loo yaqaan dareemaha aqoonsiga dhululubada, si loo kala saaro dareemaha booska crankshaft (CPS), dareemaha booska camshaft waxaa guud ahaan matala CIS. Shaqada dareemaha booska camshaft waa inuu ururiyo calaamadda booska ee shafka waalka oo uu geliyo ECU, si ECU ay u aqoonsato bartamaha sare ee cadaadiska dhululubada 1, si loo sameeyo xakamaynta duritaanka shidaalka ee isku xiga, xakamaynta waqtiga shidista iyo xakamaynta deflagging. Intaa waxaa dheer, calaamadda booska camshaft waxaa loo isticmaalaa in lagu aqoonsado daqiiqadda ugu horreysa ee shidista marka matoorku bilaabo. Sababtoo ah dareemaha booska camshaft wuxuu aqoonsan karaa piston-ka dhululubada ee ku dhow inuu gaaro TDC, waxaa loo yaqaan dareemaha aqoonsiga dhululubada.
Waxqabadka xun ee dareemaha camshaft
01 Dhibaato ku ah bilaabista gaariga
Dhibaatada ka jirta bilaabista gaariga waa muujin cad oo muujinaysa cilladda dareemaha camshaft. Dareemaha booska camshaft wuxuu go'aamiyaa taxanaha dab-shidka ee matoorka. Marka uu fashilmo, taxanaha dab-shidku wuu baaba'aa, taasoo keenta in matoorku uu ku bilaabo dhib mararka qaarna uusan haba yaraatee bilaabin. Xaaladdani ma saamayso oo keliya waxqabadka bilowga gaariga, laakiin waxay sidoo kale sababi kartaa dhaawac dheeraad ah oo soo gaara matoorka. Sidaa darteed, marka la ogaado in gaarigu uu adag yahay in la bilaabo, waa inaad hubisaa in dareemaha camshaft uu si sax ah u shaqeynayo sida ugu dhakhsaha badan.
02 Daciifnimo dardargelin
Awood la'aanta gaariga inuu dardargeliyo waa muujin cad oo muujinaysa dhaawaca dareemayaasha camshaft. Marka dareemaha camshaft uu xumaado, ECU si sax ah uma ogaan karo isbeddelka booska camshaft. Tani waxay saameyn doontaa nidaamyada qaadashada iyo qiiqa ee matoorka, taasoo keentay in la yareeyo qaadashada iyo qiiqa nidaamka qiiqa u dhow. Maadaama qaybahan muhiimka ah aysan si sax ah u shaqeyn, gaarigu wuxuu la kulmi doonaa daal marka la dardar gelinayo, gaar ahaan marka xawaaruhu ka yar yahay 2500 RPM.
03 Isticmaalka shidaalka oo kordhay
Isticmaalka shidaalka oo kordha waa calaamad muujinaysa cilladda dareemayaasha camshaft. Marka dareemaha camshaft-ka uu cilladaysan yahay, nidaamka shidaalka ee kombiyuutarka ku shaqeeya ee gaariga wuxuu noqon karaa mid fowdo ah, taasoo keenta in afka ama irbadda lagu buufiyo shidaalka uu ka baxo nidaamka. Xaaladda duritaanka ee aan habboonayn kaliya ma kordhinayso isticmaalka shidaalka ee gaariga, laakiin waxay sidoo kale sababi kartaa in xawaaraha matoorku uusan horumari karin, gaariguna uu u muuqdo mid daciif ah. Sidaa darteed, haddii la helo koror aan caadi ahayn oo ku yimaada isticmaalka shidaalka ee gaariga, waxay noqon kartaa calaamad muujinaysa in dareemaha camshaft-ka uu cilladaysan yahay.
04 Nalalka cilladaha gaariga
Nalalka cilladaha gaariga badanaa waxay la macno yihiin in dareemayaal badan ay cillado sameyn karaan. Gaar ahaan marka dareemaha booska camshaft uu dhaawacmo, dhacdadani si gaar ah ayay u caddahay. Dareemayaasha Camshaft badanaa waa dareemayaal Hall oo saddex-silig leh, oo ay ku jiraan fiilooyinka korontada ee 12v ama 5v, fiilooyinka calaamadda iyo fiilooyinka laalaabka. Marka fiilada la soo saaro oo matoorka la shido, haddii aysan jirin wax soo saar danab calaamad ah oo u dhexeeya xariiqda calaamadda iyo xariiqda salka, tani badanaa waxay la macno tahay in dareemaha uu dhaawacmay. Xaaladdan, nalka cilladaha gaariga ayaa u badan tahay inuu shido si uu darawalka u xasuusiyo inuu sameeyo kormeer faahfaahsan.
05 Jidhku si aan caadi ahayn ayuu u ruxmaa
Ruxitaanka jirka ee aan caadiga ahayn waa muujin cad oo muujinaysa cilladda dareemaha camshaft. Marka ay dhibaato ka timaado dareemaha camshaft, qaybta xakamaynta matoorka ee gaariga waxaa laga yaabaa inaysan si sax ah u akhrin xaaladda shaqada ee matoorka, taasoo keenta shaqada matoorka oo aan degganayn iyo gariirka jirka oo aan caadi ahayn. Gariirkan badanaa wuu sii muuqdaa marka gaarigu uu xawaareynayo ama uu gaabinayo. Si loo hubiyo badbaadada wadista, marka dhibaatooyinka noocaas ah la helo, waa in la sameeyaa kormeer xirfadeed iyo dayactir waqtigeeda.
