E-Korean Daewoo izinjini, njengakunoma iyiphi enye, kunezici zokuvala ze-crankshaft - izimpawu zamafutha zangaphambili nangemuva.Funda konke mayelana nezimpawu zikawoyela ze-Daewoo, izinhlobo zazo, ukwakheka, izici nokusebenziseka kwazo, kanye nokukhetha okulungile nokushintshwa kwezimpawu zikawoyela kumamotho ahlukahlukene esihlokweni.
Iyini i-Daewoo crankshaft oil seal?
I-Daewoo crankshaft oil seal iyingxenye ye-crank mechanism yezinjini ezikhiqizwe yinhlangano yaseNingizimu Korea i-Daewoo Motors;I-O-ring sealing element (i-gland seal), ivala isilinda senjini endaweni yokuphuma yozwane kanye ne-crankshaft shank.
I-crankshaft yenjini ifakwe ebhulokhini lenjini ngendlela yokuthi amathiphu ayo womabili adlulele ngale kwe-cylinder block - i-pulley yamayunithi okushayela kanye negiya lesikhathi kuvame ukufakwa ngaphambili ku-shaft (uzwane), kanti i-flywheel ifakwe ngemuva kwe-shaft (shank).Kodwa-ke, ekusebenzeni okujwayelekile kwenjini, ibhulokhi yayo kufanele ivalwe, ngakho-ke ukuphuma kwe-crankshaft kuyo kuvalwe ngezimpawu ezikhethekile - izimpawu zamafutha.
I-crankshaft oil seal inemisebenzi emibili esemqoka:
● Ukuvala ibhulokhi yenjini ukuze kuvinjwe ukuvuza kukawoyela ngembobo yokukhipha i-crankshaft;
● Ukuvimbela ukungcola kwemishini, amanzi namagesi ukuthi angangeni enjinini.
Ukusebenza okuvamile kwayo yonke injini kuncike esimweni sophawu lwamafutha, ngakho-ke uma kwenzeka umonakalo noma ukuguga, le ngxenye kufanele ishintshwe ngokushesha ngangokunokwenzeka.Ukuze uthenge okulungile nokushintshwa kwe-gland seal entsha, kuyadingeka ukuqonda izinhlobo, izici kanye nokusebenziseka kwezimpawu zamafutha e-Daewoo.
Idizayini, izinhlobo kanye nokusebenziseka kwama-Daewoo crankshaft oil seals
Ngokwesakhiwo, zonke izimpawu zikawoyela ze-crankshaft yezimoto ze-Daewoo ziyefana - lena indandatho yerabha (irabha) yephrofayili emise okwe-U, ngaphakathi kwayo okungase kube khona indandatho yasentwasahlobo (isiphethu esisontekile esincanyana esigoqwe esiyindandatho) ukuze uthole ukulingana okuthembekile ku-shaft.Ngaphakathi kwesigxivizo sikawoyela (eceleni kwendandatho yokuxhumana ne-crankshaft), amanotshi okuvala asetshenziswa ukuze kuqinisekiswe ukuthi imbobo yokuphuma ku-shaft ivaliwe ngesikhathi sokusebenza kwenjini.
I-oil seal ifakwe emgodini we-cylinder block ukuze i-groove yayo ibheke ngaphakathi.Kulesi simo, indandatho yayo yangaphandle ithintana nodonga lwebhulokhi (noma isembozo esikhethekile, njengalapho kufakwe uphawu lwamafutha angemuva), futhi indandatho yangaphakathi ihlezi ngqo ku-shaft.Ngesikhathi sokusebenza kwenjini, ingcindezi eyengeziwe idalwe ku-block, ecindezela izindandatho zophawu lwamafutha ku-block kanye ne-shaft - lokhu kuqinisekisa ukuqina kokuxhumeka, okuvimbela ukuvuza kwamafutha.
Isigxivizo samafutha sangemuva kumshini we-crank wezinjini ze-Daewoo
Izigxivizo zamafutha e-Daewoo crankshaft zihlukaniswe zaba izinhlobo eziningana ngokuya ngezinto zokwenziwa, ukuba khona kwebhuthi kanye nomklamo wayo, isiqondiso sokujikeleza kwe-crankshaft, kanye nenjongo, ubukhulu kanye nokusebenza.
Izimpawu zikawoyela zenziwe ngamamaki akhethekile enjoloba (ama-elastomers), ezimotweni ze-Daewoo kunezingxenye ezenziwe ngezinto ezilandelayo:
● I-FKM (FPM) - i-fluororubber;
● I-MVG (VWQ) - irabha ye-organosilicon (silicone);
● I-NBR - irabha ye-nitrile butadiene;
● I-ACM iyirabha ye-acrylate (polyacrylate).
Izinhlobo ezehlukene zenjoloba zinokumelana okuhlukile kwezinga lokushisa, kodwa ngokwamandla emishini nezimfanelo zokungakhuni, azihlukile neze.Izinto zokwenziwa kophawu lwamafutha zivame ukukhonjiswa ekuphawuleni ohlangothini lwayo olungaphambili, futhi kuboniswe kulebula yengxenye.
Izigxivizo zikawoyela zingaba nama-anther emiklamo ehlukahlukene:
● I-Petal (unqenqema olungangenwa uthuli) ngaphakathi kwesivalo sikawoyela (ebheke ku-crankshaft);
● I-anther eyengeziwe ngendlela yeringi ezwakalayo eqinile.
Imvamisa, ama-seal amaningi kawoyela e-Daewoo crankshaft ane-anther emise okwepethali, kodwa kunezingxenye emakethe ezinamabhuzu azizwayo anikeza ukuvikeleka okuthembekile othulini nokunye ukungcola kwemishini.
Ngokwesiqondiso sokujikeleza kwe-crankshaft, izimpawu zikawoyela zihlukaniswe izinhlobo ezimbili:
● Ukuzulazula kwesokudla (ngokwewashi);
● Ngokuzungeza kwesokunxele (ngokuphambene newashi).
Umehluko omkhulu phakathi kwalezi zimpawu zikawoyela isiqondiso samanotshi avela ngaphakathi, atholakala nge-diagonally kwesokudla noma kwesobunxele.
Ngokusho kwenhloso, kunezinhlobo ezimbili zezimpawu zikawoyela:
● Ngaphambili - ukuvala indawo yokuphuma ku-shaft kusukela ohlangothini lozwane;
● Ngemuva - ukuvala indawo yokuphuma ku-shaft ohlangothini lwe-shank.
Izimpawu zangaphambili zikawoyela zincane, ngoba zivala uzwane lwe-shaft kuphela, lapho kufakwe khona igiya lesikhathi kanye ne-drive pulley yamayunithi.Izigxivizo zikawoyela zangemuva zine-diameter ekhuphukile, njengoba zifakwe ku-flange etholakala ku-crankshaft shank ebamba i-flywheel.Ngesikhathi esifanayo, ukuklama kwezimpawu zamafutha azo zonke izinhlobo kufana ngokuyisisekelo.
Ngokuqondene nobukhulu, izinhlobonhlobo eziningi zamafutha zisetshenziswa ezimotweni ze-Daewoo nezinye izinhlobo ezinezinjini ze-Daewoo, kodwa ezivame kakhulu yilezi ezilandelayo:
● 26x42x8 mm (ngaphambili);
● 30x42x8 mm (ngaphambili);
● 80x98x10 mm (ngemuva);
● 98x114x8 mm (ngemuva).
Uphawu lwamafutha lubonakala ngezilinganiso ezintathu: ububanzi bangaphakathi (ububanzi be-shaft, buboniswe kuqala), ububanzi obungaphandle (ububanzi bomgodi ofakayo, oboniswa okwesibili) nokuphakama (okuboniswa okwesithathu).

I-Rear Crankshaft Oil SealUkubuka kwe-Front Crankshaft Oil Seal
Iningi lamafutha e-Daewoo seal akhona emhlabeni wonke - afakwe kumamodeli amaningana nemigqa yamayunithi wamandla, afakwe amamodeli ezimoto ahlukahlukene.Ngakho-ke, kumodeli efanayo yemoto enamayunithi amandla ahlukene, kusetshenziswa izimpawu zamafutha ezingalingani.Isibonelo, ku-Daewoo Nexia enenjini engu-1.5-litre, i-front oil seal ene-diameter yangaphakathi engu-26 mm isetshenziswa, futhi ngezinjini ezingu-1.6-litre zisebenzisa uphawu lwamafutha olunobubanzi obungama-30 mm.
Ekuphetheni, kufanele kushiwo mayelana nokusetshenziswa kwezimpawu zamafutha e-Daewoo ezimotweni ezihlukahlukene.Kuze kube ngu-2011, i-Daewoo Motors Corporation yakhiqiza amamodeli emoto amaningana, kuhlanganise nedume kakhulu ezweni lakithi iMatiz neNexia.Ngesikhathi esifanayo, inkampani yakhiqiza amamodeli e-Chevrolet Lacetti angavamile, futhi izinjini ze-Daewoo (futhi zi) zifakwe kwezinye izinhlobo ze-General Motors (le nkampani yathola isigaba se-Daewoo Motors ngo-2011) - i-Chevrolet Aveo, i-Captiva ne-Epica.Ngakho-ke, namuhla i-Daewoo crankshaft oil seals yezinhlobo ezahlukene isetshenziswa kokubili kumamodeli "akudala" alolu hlobo lwaseKorea, futhi kumamodeli amaningi ama-Chevrolet amadala namanje - konke lokhu kufanele kucatshangelwe lapho ukhetha izingxenye ezintsha zemoto.
I-Radial (emise okwe-L) i-PXX cishe inohlelo olufanayo, kodwa ingasebenza nezinjini ezinamandla kakhulu.Zibuye zisekelwe ku-stepper motor, kodwa ku-axis ye-rotor yayo (armature) kukhona isibungu, esihlanganisa i-counter gear, sizungeza ukugeleza kwe-torque ngama-degree angu-90.I-stem drive ixhunywe egiyeni, okuqinisekisa ukunwetshwa noma ukuhoxiswa kwe-valve.Sonke lesi sakhiwo sitholakala endlini emise okwe-L enezinto ezikhwezayo kanye nesixhumi esijwayelekile sikagesi sokuxhuma ku-ECU.
I-PXX ene-valve yomkhakha (damper) isetshenziswa ezinjinini ezinomthamo omkhulu wezimoto, ama-SUV namaloli okuhweba.Isisekelo sedivayisi yi-stepper motor ene-armature engaguquki, lapho i-stator enamazibuthe angapheli ingajikeleza.I-stator yenziwe ngendlela yengilazi, ifakwe ekuthwaleni futhi ixhunywe ngokuqondile ku-flap yomkhakha - ipuleti evimbela iwindi phakathi kwamapayipi okungena nokuphuma.I-RHX yalo mklamo yenziwa esimweni esifanayo namapayipi, axhunywe kumhlangano we-throttle kanye nomamukeli ngokusebenzisa ama-hoses.Futhi ecaleni kukhona isixhumi esijwayelekile sikagesi.
Ukukhetha okulungile nokushintshwa kwe-Daewoo crankshaft oil seal
Ngesikhathi sokusebenza kwenjini, izigxivizo zamafutha e-crankshaft zingaphansi kwemithwalo ebalulekile yemishini neyokushisa, okuholela kancane kancane ekugqokeni nasekulahlekelweni kwamandla.Esikhathini esithile, ingxenye iyayeka ukwenza imisebenzi yayo ngokujwayelekile - ukuqina komgodi wokuphuma kwe-shaft kuphukile futhi kuvela ukuvuza kwamafutha, okuthinta kabi ukusebenza kwenjini.Kulokhu, i-Daewoo crankshaft oil seal kumele ishintshwe.
Ukuze ushintshe, kufanele ukhethe izimpawu zamafutha ezifanele ngobukhulu nokusebenza - lapha imodeli yenjini kanye nonyaka wokwakhiwa kwemoto kuyacatshangelwa.Ukunakwa okukhethekile kufanele kukhokhwe ezintweni zokwenziwa kophawu lwamafutha.Isibonelo, ezimotweni ezisebenza endaweni epholile, izingxenye zangempela ze-FKM (FPM) ze-fluororubber zifanelekile - zisebenza ngokuzethemba kufika ku--20 ° C nangaphansi, kuyilapho zigcina ukuqina nokumelana nokugqoka.Kodwa-ke, ezifundeni ezisenyakatho nezifunda ezinobusika obubandayo, kungcono ukukhetha i-MVG silicone oil seals (VWQ) - igcina ukunwebeka kuze kufike ku--40 ° C nangaphansi, okuqinisekisa ukuqala ngokuzethemba kwenjini ngaphandle kwemiphumela yokuthembeka. izigxivizo zamafutha.Ezinjinini ezilayishwe kancane, uphawu lukawoyela olwenziwe ngerabha ye-nitrile butadiene (NBR) nalo luzoba yisixazululo esihle - lugcina ukunwebeka kuze kufike ku--30 ... -40 ° C, kodwa alukwazi ukusebenza emazingeni okushisa angaphezu kuka-100 ° C.
Ukumelana nokushisa kwezimpawu zamafutha e-crankshaft ezenziwe ngezinto ezihlukahlukene
Uma imoto iqhutshwa ezimweni ezinothuli, khona-ke kunengqondo ukukhetha ama-seals kawoyela nge-boot eyengeziwe ezwayo.Kodwa-ke, udinga ukuqonda ukuthi abakhiqizi be-Daewoo noma i-OEM balezi zimpawu zamafutha akhiqizwayo, lezi izingxenye ezingezona ezangempela manje ezinikezwa abakhiqizi basekhaya nabangaphandle bemikhiqizo yenjoloba.
Ukushintshwa kwe-crankshaft oil seal kwenziwa ngokuhambisana nemiyalelo yokulungisa nokusebenza kwezinjini ezihambisanayo nezimoto iDaewoo neChevrolet.Imvamisa, lokhu kusebenza akudingi ukuhlakazwa kwenjini - kwanele ukudiliza idrayivu yamayunithi kanye nesikhathi (uma kushintsha uphawu lwamafutha angaphambili), kanye ne-flywheel nge-clutch (uma kwenzeka kushintshwa uwoyela ongemuva. uphawu).Ukususwa kophawu lwamafutha oludala kwenziwa kalula nge-screwdriver noma elinye ithuluzi elikhonjiwe, futhi kungcono ukufaka entsha usebenzisa ithuluzi elikhethekile elisesimweni sendandatho, lapho uphawu lwamafutha lufakwa ngalo ngokulinganayo esihlalweni (ukugcwalisa). ibhokisi).Kwamanye amamodeli enjini, ukubuyisela uphawu lwamafutha angemuva kungase kudinge ukuqaqa sonke isembozo (isihlangu), esibanjwe ebhulokhini ngamabhawodi.Ngesikhathi esifanayo, kunconywa ukuhlanza kuqala indawo yokufaka uphawu lwamafutha kumafutha nokungcola, ngaphandle kwalokho ukuvuza okusha nokulimala kungase kuvele ngokushesha.
Ngokukhetha okulungile nokushintshwa kwe-Daewoo crankshaft oil seal, injini izosebenza ngokwethembeka ngaphandle kokulahlekelwa uwoyela nokugcina izici zayo kuzo zonke izimo.
