Kwiinjini zeDaewoo zaseKorea, njengakuyo nayiphi na enye, kukho izinto zokutywina ze-crankshaft - izitywina zeoyile zangaphambili nangasemva.Funda konke malunga namatywina e-oyile ye-Daewoo, iintlobo zazo, ukuyila, iimpawu kunye nokusebenziseka, kunye nokukhetha okuchanekileyo kunye nokutshintshwa kweoli yeoli kwiinjini ezahlukeneyo kwinqaku.
Yintoni iDaewoo crankshaft oil seal?
I-Daewoo crankshaft oil seal yinxalenye yecrank mechanism yeenjini eziveliswe liqumrhu laseMzantsi Korea iDaewoo Motors;Into yokutywina ye-O-ring (i-gland seal), ukutywina ibhloko yesilinda ye-injini kwindawo yokuphuma yezwane kunye ne-crankshaft shank.
I-crankshaft ye-injini ifakwe kwibloko ye-injini ngendlela yokuba zombini iincam zayo zidlulele ngaphaya kwebloko yesilinda - i-pulley yezixhobo zokuqhuba kunye ne-timing gear zivame ukufakwa ngaphambili kwi-shaft (izwane), kunye ne-flywheel. ifakwe ngasemva kweshaft (shank).Nangona kunjalo, ekusebenzeni okuqhelekileyo kwe-injini, ibhloko yayo kufuneka itywinwe, ngoko i-crankshaft ephuma kuyo itywinwe ngamatywina akhethekileyo-izitywina zeoyile.
Itywina leoli ye-crankshaft inemisebenzi emibini ephambili:
● Ukutywina ibhloko ye-injini ukuze kuthintelwe ukuvuza kwe-oyile kumngxuma wokukhupha i-crankshaft;
● Ukuthintela ukungcola koomatshini, amanzi neegesi ukuba zingangeni kumqobo wenjini.
Ukusebenza okuqhelekileyo kwe-injini yonke kuxhomekeke kwimeko ye-oil seal, ngoko ke xa kwenzeka umonakalo okanye ukuguga, le nxalenye kufuneka itshintshwe ngokukhawuleza.Ukwenza ukuthengwa ngokufanelekileyo kunye nokutshintshwa kwetywina elitsha le-gland, kuyimfuneko ukuqonda iintlobo, iimpawu kunye nokusetyenziswa kwe-oyile ye-Daewoo.
Uyilo, iintlobo kunye nokusetyenziswa kwe-Daewoo crankshaft oil seals
Ngokwesakhiwo, onke amatywina e-oyile ye-crankshaft yeemoto ze-Daewoo ziyafana - le yirabha (irabha) ikhonkco yeprofayili e-U, ngaphakathi apho kunokubakho umsesane wasentwasahlobo (intwasahlobo encinci ephothiweyo egqitywe kwindandatho) ukufaneleka okuthembekileyo kwi-shaft.Ngaphakathi kwesitywina se-oyile (kunye neringi yokudibanisa kunye ne-crankshaft), iinotshi zokutywina ziyafakwa ukuqinisekisa ukuba umngxuma wokuphuma kwe-shaft uvalwe ngexesha lokusebenza kwe-injini.
Isitywina seoli sifakwe emngxunyeni webhloko yesilinda ukwenzela ukuba i-groove yayo ijonge ngaphakathi.Kule meko, indandatho yayo yangaphandle idibene nodonga lwebhloko (okanye isigqubuthelo esikhethekileyo, njengakwimeko ye-oyile yangasemva), kwaye i-ring yangaphakathi ixhomekeke ngqo kwi-shaft.Ngethuba lokusebenza kwe-injini, uxinzelelo olwandisiweyo lwenziwa kwibhloko, ecinezela amakhonkco e-oyile yokutywina kwibhloko kunye ne-shaft - oku kuqinisekisa ukuqina koqhagamshelwano, okuthintela ukuvuza kweoli.
Isitywina se-oyile yangasemva kwindlela ye-crank yeenjini ze-Daewoo
Iitywina zeoyile yeDaewoo crankshaft zahlulwe zaba ziindidi ezininzi ngokwezinto ezenziweyo, ubukho bebhuthi kunye noyilo lwayo, isalathiso sokujikeleza kwe-crankshaft, kunye nenjongo, ubungakanani kunye nokusebenza.
Izitywina zeoyile zenziwe ngamabakala akhethekileyo erabha (elastomers), kwiimoto zeDaewoo kukho iinxalenye ezenziwe ngezi zinto zilandelayo:
● FKM (FPM) - fluororubber;
● I-MVG (VWQ) - i-organosilicon (i-silicone) irabha;
● I-NBR - irabha ye-nitrile butadiene;
● I-ACM yirubha ye-acrylate (polyacrylate).
Iindidi ezahlukeneyo zerabha zinokuxhathisa ubushushu okwahlukileyo, kodwa ngokwamandla omatshini kunye neempawu zokuchasana ne-antifriction, azifani.Izinto eziphathekayo zokwenziwa kwetywina leoli zidla ngokuboniswa ekumakishweni kwicala langaphambili, likwaboniswa kwileyibhile yenxalenye.
Iimpawu zeoyile zinokuba ne-anthers yoyilo olwahlukeneyo:
● Ipetali (ingqameko elingangenwa luthuli) ngaphakathi kwitywina leoli (ejongene necrankshaft);
● I-anther eyongezelelweyo ngohlobo lweringi eqinileyo.
Ngokwesiqhelo, uninzi lwezitywina zeoyile ye-Daewoo crankshaft zine-petal-shaped anther, kodwa kukho iindawo emarikeni ezineebhutsi eziveziweyo ezibonelela ngokhuseleko oluthembekileyo eluthulini nakwezinye izinto ezingcolisa oomatshini.
Ngokolwalathiso lokujikeleza kwe-crankshaft, izitywina zeoyile zohlulwe zibe ziindidi ezimbini:
● Ukushukuma ngasekunene (ngokuhamba kwewotshi);
● Ngokujikeleza ngasekhohlo (ngokuchasene newotshi).
Umahluko ophambili phakathi kwezi zitywina zeoyile lulwalathiso lweenotshi ukusuka ngaphakathi, zibekwe ngediagonally ukuya ngasekunene okanye ngasekhohlo.
Ngokwenjongo, kukho iindidi ezimbini zeoli ye-oyile:
● Ngaphambili - ukutywina indawo yokuphuma kweshaft ukusuka kwicala lenzwane;
● Ngasemva - ukutywina indawo yokuphuma kweshaft ukusuka kwicala le-shank.
Iimpawu zeoli zangaphambili zincinci, kuba zitywina kuphela inzwane ye-shaft, apho i-gear timeing kunye ne-drive pulley yeeyunithi zifakwe khona.Amatywina e-oyile angasemva anedayamitha eyongeziweyo, njengoko zixhonywe kwiflange ebekwe kwi-crankshaft shank ebambe i-flywheel.Kwangaxeshanye, uyilo lwezitywina zeoyile zazo zonke iintlobo ziyafana.
Ngokubhekiselele kwimilinganiselo, iintlobo ezininzi zeetywina zeoyile zisetyenziswa kwiimoto ze-Daewoo kunye nezinye iimveliso ezineenjini zeDaewoo, kodwa ezona zixhaphakileyo zezi zilandelayo:
● 26x42x8 mm (ngaphambili);
● 30x42x8 mm (ngaphambili);
● 80x98x10 mm (ngasemva);
● 98x114x8 mm (ngasemva).
Ukutywinwa kweoli kubonakaliswe ngemilinganiselo emithathu: ububanzi bangaphakathi (ububanzi be-shaft, bubonakaliswe kuqala), ububanzi bangaphandle (ububanzi bomngxuma onyukayo, obonakaliswe ngowesibini) kunye nokuphakama (kuboniswe ngowesithathu).

Ngasemva Crankshaft Oyile SealImboniselo ye-Oli yeCrankshaft yangaphambili
Uninzi lwezitywina zeoyile ye-Daewoo zizonke - zifakwe kwiimodeli ezininzi kunye nemigca yeeyunithi zamandla, ezixhotyiswe ngeemodeli ezahlukeneyo zeemoto.Ngokufanelekileyo, kwimodeli yemoto efanayo kunye neeyunithi zamandla ahlukeneyo, izitywina zeoyile ezingalinganiyo zisetyenziswa.Ngokomzekelo, kwi-Daewoo Nexia ene-injini ye-1.5-litre, i-oyile yangaphambili yotywina kunye nobubanzi obungaphakathi be-26 mm isetyenzisiweyo, kunye ne-injini ye-1.6-litre, i-oil seal kunye ne-30 mm yangaphakathi isetyenziswa.
Ekugqibeleni, kufuneka kuthiwe malunga nokusebenza kweoli ye-Daewoo kwiimoto ezahlukeneyo.Ukuza kuthi ga ngo-2011, i-Daewoo Motors Corporation ivelise iimodeli ezininzi zeemoto, kuquka ezona zidumileyo kwilizwe lethu iMatiz kunye neNexia.Kwangaxeshanye, inkampani yavelisa iimodeli ze-Chevrolet Lacetti ezingaziwayo, kwaye iinjini ze-Daewoo zaye (kwaye zi) zifakwe kwezinye iimodeli zeGeneral Motors (le nkampani yafumana icandelo leDaewoo Motors ngo-2011) - iChevrolet Aveo, iCaptiva kunye ne-Epica.Ke ngoko, namhlanje i-Daewoo crankshaft izitywini zeoyile zeentlobo ezahlukeneyo zisetyenziswa zombini kwiimodeli ze "classic" zolu hlobo lwaseKorea, kwaye kwiimodeli ezininzi zakudala kunye nezangoku zeChevrolet - konke oku kufuneka kuthathelwe ingqalelo xa ukhetha iinxalenye ezintsha zemoto.
Radial (L-shaped) PXX malunga nesicelo esifanayo, kodwa inokusebenza ngeenjini ezinamandla ngakumbi.Zikwasekelwe kwi-motor stepper, kodwa kwi-axis ye-rotor yayo (i-armature) kukho imbungu, leyo, kunye ne-counter gear, ijikeleza ukuhamba kwe-torque ngama-90 degrees.I-stem drive ixhunyiwe kwi-gear, eqinisekisa ukwandiswa okanye ukuchithwa kwevalve.Esi sakhiwo siphela sifumaneka kwizindlu ezibunjwe ngu-L kunye nezinto ezikhulayo kunye nekhonkco lombane eliqhelekileyo lokuxhuma kwi-ECU.
I-PXX enevalve yecandelo (i-damper) isetyenziswa kwiinjini zomthamo omkhulu weemoto, ii-SUV kunye neelori zorhwebo.Isiseko sesixhobo yinjini ye-stepper ene-armature esisigxina, apho i-stator enemagnethi esisigxina inokujikeleza.I-stator yenziwe ngendlela yeglasi, ifakwe kwi-bearing kwaye idibaniswe ngokuthe ngqo kwi-flap yecandelo - iplate evimba ifestile phakathi kweepayipi zokungena kunye nokuphuma.I-RHX yolu qulunqo lwenziwe kwimeko efanayo kunye nemibhobho, edityaniswe kwindibano ye-throttle kunye nommkeli ngokusebenzisa i-hoses.Kwakhona kwimeko kukho ikhonkco lombane eliqhelekileyo.
Ukhetho olufanelekileyo kunye nokutshintshwa kwe-Daewoo crankshaft oil seal
Ngexesha lokusebenza kwe-injini, izitywina zeoyile ye-crankshaft ziphantsi komthwalo obalulekileyo oomatshini kunye ne-thermal, ethi ngokuthe ngcembe ikhokelele ekunxityweni nasekuphulukaneni namandla.Ngexesha elithile, inxalenye iyayeka ukwenza imisebenzi yayo ngokuqhelekileyo - ukunyanzeliswa komngxuma wokuphuma kwe-shaft kuphukile kwaye kubonakala ukuvuza kweoli, okuchaphazela kakubi ukusebenza kwe-injini.Kule meko, i-Daewoo crankshaft oil seal kufuneka itshintshwe.
Ukutshintshwa, kufuneka ukhethe izitywina zeoli ezifanelekileyo ngobukhulu kunye nokusebenza - apha imodeli ye-injini kunye nonyaka wokwenziwa kwemoto ithathelwa ingqalelo.Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwizinto zokwenziwa kwetywina leoli.Ngokomzekelo, kwiimoto ezisebenza kwimozulu epholileyo, i-FKM yokuqala (i-FPM) i-fluororubber parts ifanelekile-isebenza ngokuzithemba ukuya kuthi ga kwi-20 ° C nangaphantsi, ngelixa igcina i-elasticity kunye nokumelana nokugqoka.Nangona kunjalo, kwimimandla esemantla kunye nemimandla enobusika obubandayo, kungcono ukhethe i-MVG silicone oil seals (VWQ) - igcina i-elasticity ukuya kwi -40 ° C nangaphantsi, eqinisekisa ukuqala ngokuzithemba kwe-injini ngaphandle kwemiphumo yokuthembeka amatywina oyile.Kwiinjini ezilayishwe kancinci, i-oil seal eyenziwe ngerubha ye-nitrile butadiene (NBR) nayo iya kuba sisisombululo esihle - zigcina ukuqina ukuya kuthi ga -30 ... -40 ° C, kodwa azikwazi ukusebenza kumaqondo obushushu angaphezu kwe-100 ° C.
Ukumelana nokushisa kwe-crankshaft oil seals eyenziwe ngezinto ezahlukeneyo
Ukuba imoto iqhutywe kwiimeko ezinothuli, ngoko kunengqiqo ukukhetha izitywina zeoli kunye ne-boot eyongezelelweyo evakalelwa.Nangona kunjalo, kufuneka uqonde ukuba akukho Daewoo okanye ababoneleli be-OEM bezo zitywina zeoyile baveliswayo, ezi ziindawo ezingezizo ezoqobo ngoku ezibonelelwa ngabavelisi basekhaya nabangaphandle beemveliso zerabha.
Ukutshintshwa kwetywina leoli ye-crankshaft kuqhutyelwa ngokuhambelana nemiyalelo yokulungiswa kunye nokusebenza kweenjini ezihambelanayo kunye neemoto zeDaewoo kunye neChevrolet.Ngokuqhelekileyo, lo msebenzi awufuni ukuchithwa kwe-injini - kwanele ukukhupha i-drive yeeyunithi kunye nexesha (kwimeko yokutshintsha itywina langaphambili le-oyile), kunye ne-flywheel kunye ne-clutch (kwimeko yokutshintsha ioli yangasemva. itywina).Ukususwa kwetywina elidala le-oyile kwenziwa ngokulula nge-screwdriver okanye esinye isixhobo esichongiweyo, kwaye kungcono ukufakela esitsha usebenzisa isixhobo esikhethekileyo ngendlela yomsesane, apho isitywina se-oyile sifakwe ngokulinganayo esihlalweni (izinto ezifakwayo. ibhokisi).Kwezinye iimodeli ze-injini, ukubuyisela isitywina se-oyile yangasemva kunokufuna ukudilizwa kwesigqubuthelo sonke (ikhaka), esibanjwa kwibhloko ngeebholiti.Ngexesha elifanayo, kucetyiswa ukuba uhlambulule kwangaphambili indawo yokufakela isitywina seoli kwioli kunye nokungcola, ngaphandle koko ukuvuza okutsha kunye nomonakalo unokubonakala ngokukhawuleza.
Ngokukhetha okufanelekileyo kunye nokutshintshwa kwe-oyile ye-Daewoo crankshaft seal, injini iya kusebenza ngokuthembekileyo ngaphandle kokulahlekelwa yioli kunye nokugcina iimpawu zayo kuzo zonke iimeko.
