Ezinjini ezivuthayo zangaphakathi ezine-belt drive yomshini wokusabalalisa igesi, kuyadingeka ukuqinisekisa isikhundla esifanele sebhande kanye nokuzinza kwalo ngesikhathi sokusebenza.Le misebenzi ixazululwa ngosizo lwama-bypass rollers, inhloso, ukuklama nokushintshwa okuchazwe ngokuningiliziwe kulesi sihloko.
Iyini i-time bypass roller?
I-bypass (ukusekelwa, okuphakathi, i-parasitic) i-roller iyisici esisizayo se-belt drive ye-gas distribution mechanism (isikhathi), i-pulley ejikelezayo yamahhala ye-diameter encane, lapho ibhande lesikhathi lizungezwe endaweni ethile (noma amaphuzu. ).
Irola yokudlula isikhathi ixazulula izinkinga ezimbalwa:
• Ukushintsha ukuhamba kwebhande (ukuphendukela ku-angle edingekayo) ngokuhambisana nendawo ye-camshaft pulleys kanye nezinamathiselo;
• Ukuqedwa kokudlidliza kwamagatsha ebhande ngobude bawo obukhulu;
• Ukuqiniswa kwebhande lesikhathi ngesikhathi sokusebenza, ukuvimbela izenzakalo ze-resonance, i-slippage, njll.;
• Ukwehliswa okuphelele komsindo wendlela yokusabalalisa igesi.
Esikhathini sokushayela ibhande lesikhathi, i-bypass roller eyodwa ivame ukusetshenziswa, kancane kancane, kodwa izinjini eziningi zesimanje ezinevolumu encane azinazo nhlobo lezi zingxenye.Ngesikhathi esifanayo, umuntu akufanele adidanise i-bypass roller nenye indlela efanayo - i-tension roller.I-tension roller inikeza ukungezwani okudingekayo kwebhande, ivimbele ukuthi lingasheleli kanye nokuphulwa kwenjini okuhlobene, futhi yenza nemisebenzi ye-bypass roller endleleni.Ngokuzayo, sizokhuluma ngama-bypass rollers.
Izinhlobo nokuklama kwamarola we-bypass wesikhathi
Kungakhathaliseki ukuthi hlobo luni, wonke ama-bypass rollers ahlelwe ngendlela efanayo.Isisekelo se-roller siyi-bearing, endandeni yangaphandle lapho i-pulley icindezelwa khona.I-bearing i-radial (ibona kuphela imithwalo eqondiswe eduze kwe-radius), ibhola noma i-roller, ingaba umugqa owodwa ojwayelekile noma umugqa okabili obanzi.Ubuso bokugcina be-bearing bungavalwa ngesembozo sensimbi noma umkhono ukuze kuvikelwe ukungcola, uthuli, amanzi kanye noketshezi lobuchwepheshe.I-pulley iyinsimbi egxiviziwe noma ipulasitiki eqinile, engahlukaniseki, kuye ngohlobo lwenjini, inobubanzi nobubanzi obuhlukile.
Ama-Bypass rollers angaba ne-pulley eyenziwe ngezinto ezihlukahlukene:
• Insimbi - i-aluminium alloy noma insimbi;
•Ipulasitiki.
Isibonelo sedrayivu yesikhathi enama-bypass roller amabili amadayamitha ahlukene
Njengamanje, ama-roller epulasitiki asetshenziswa kabanzi, ashibhile kunezinsimbi, kuyilapho enikeza umsindo omncane futhi enciphisa isisindo sonke sesistimu.Ipulasitiki ingaphansi kokuguga, kodwa insiza yama-bypass roller epulasitiki yesimanje muhle, ngokuvamile asebenzisa sonke isikhathi sesevisi (phakathi kokushintshwa kwebhande).
Ama-Roller Metal asetshenziswa ezinjinini ezinamandla futhi ezilayishwe kakhulu, lapho kubalulekile ukuqinisekisa ukwethembeka kwedrayivu yesikhathi kuzo zonke izindlela.
Ama-Roller angaba nama-pulley anezinhlobo ezahlukene zezindawo zokusebenza (imigwaqo yomjaho):
• Bushelelezi - indawo yokusebenza ibushelelezi, ayinakho okungahambi kahle;
• I-Corrugated - indawo yokusebenza inemigodi emide yokujula okungajulile, lo mklamo unciphisa indawo yokuxhumana ye-pulley ngebhande;
• Kunamazinyo - indawo esebenzayo inamazinyo anqamulayo, lena i-pulley enamazinyo ejikelezayo mahhala.
Ngesikhathi esifanayo, ama-roller ane-pulley ebushelelezi ne-corrugated angenziwa kokubili kwepulasitiki nensimbi, futhi ama-roller anamazinyo ayinsimbi kuphela - insimbi noma i-aluminium alloys.
Irola yokudlula enamazinyo
Ama-roller abushelelezi futhi ane-grooved afakwe ngendlela yokuthi ibhande liwamboze ngohlangothi lwawo lwangemuva (obushelelezi).Ama-roller anamazinyo ahlelwe ngendlela yokuthi ibhande libamboze ngohlangothi lwalo lokusebenza (olunamazinyo).Ukushintsha ama-roller ohlobo olulodwa nolunye akwamukelekile, njengoba lokhu kushintsha izici zohlelo lonke futhi kugcwele ukuwohloka kwenjini.
Okokugcina, ama-bypass roller pulleys, kungakhathaliseki ukuthi hlobo luni, angaba nezinguqulo ezimbili:
• Ngaphandle kwama-thrust collars;
• Ngama-thrust collars.
Esimweni sesibili, i-pulley ohlangothini olulodwa noma zombili izinhlangothi inamakholomu okuphakama okuncane okuvimbela ibhande ukuthi lingasheleli.Kuma-roller abushelelezi epulasitiki nensimbi, ikhola, njengomthetho, yenza iyunithi eyodwa nge-pulley, igxivizwe, iphonswe noma iguqulwe.Kuma-roller anamazinyo, ikhola ohlangothini olulodwa noma zombili izinhlangothi ingenziwa ngendlela yamasongo akhishwayo, afakwa lapho i-roller ifakwe enjinini.
Ukufakwa kwe-bypass roller enjinini kwenziwa ngezindlela ezimbili:
• Ngqo kwibhulokhi yenjini;
• Ukusebenzisa ubakaki ohlukile.
Esimweni sokuqala, i-roller ne-bearing yayo ihlezi endaweni yesikhulumi esihlinzekwe ngokukhethekile ku-injini ye-injini futhi ihlanganiswe ne-bolt eyodwa (ngokusebenzisa i-washer ye-diameter eyengeziwe).Esimweni sesibili, i-roller igxiliwe kubakaki, yona, ifakwe ku-injini yenjini ngama-bolts amabili noma ngaphezulu.
Ukukhethwa, ukushintshwa kanye nokusebenza kwama-roller odlula isikhathi
Ama-Bypass rollers ayaguga ngesikhathi sokusebenza futhi adinga ukushintshwa - lokhu kusebenza kwenziwa kanyekanye nokushintshwa kwebhande lesikhathi kanye ne-tension roller.Zonke lezi zingxenye, njengomthetho, zithengiswa kukhithi, ngakho-ke asikho isidingo sokubheka ngokwehlukana i-roller ne-fasteners yayo.Uma uthenga ibhande nama-roller, kufanele ucabangele izincomo zomkhiqizi wenjini bese ukhetha izingxenye zezinhlobo ezifanele nezinombolo zekhathalogi.
Kwezinye izimo, i-roller ingawohloka noma yehluleke ngokuphelele.Ngokuvamile, izinkinga ziphakama ekuthwaleni, lapho kwenzeka umsindo ongaphandle ngesikhathi sokusebenza kwenjini.I-roller pulley ibangela izinkinga kancane kakhulu.Kunoma yikuphi, i-roller kufanele ishintshwe, ngoba lokhu udinga ukuthenga ingxenye entsha ngokuvumelana nemiyalelo yomkhiqizi futhi wenze umsebenzi ngokuhambisana nemiyalelo yokulungisa nokugcinwa kwale moto ethile.
Ngesikhathi sokusebenza, i-bypass roller ayidingi ukunakekelwa okukhethekile, ngokuvamile le ngxenye isebenza ngokujwayelekile phakathi nenkathi yesevisi futhi ayibangeli izinkinga.
Umzimba kanye ne-lens ye-headlamp imakwe ngezici zayo eziyinhloko kanye nezinhlobo zezibani ezingafakwa.Ukufakwa kweminye imithombo yokukhanya akwamukelekile (ngaphandle kokungavamile), lokhu kungashintsha izici zokukhanya, futhi ngenxa yalokho, imoto ngeke idlule ukuhlolwa.
Izinkinga zokukhetha, ukushintshwa kanye nokusebenza kwezibani zemoto
Ukukhetha ama-optics amasha, kuyadingeka ukucabangela ukuklama, izici nezici zemikhiqizo emidala, ngokufanelekile kufanele uthenge i-headlight yemodeli efanayo.Uma sikhuluma ngezibani zenkungu noma izibani zokusesha kanye nezibani zokusesha ezazingekho emotweni, khona-ke lapha kufanele ucabangele ukuthi kungenzeka yini ukufaka lawa madivaysi emotweni (ukuba khona kwabakaki abafanelekile, njll.) nezici zabo.
Ukunakwa okukhethekile kufanele kukhokhwe ekukhethweni kwezibani zangaphambili.Namuhla, zivame ukwethulwa ngezinguqulo ezimbili - ngengxenye esobala (emhlophe) nephuzi yesiginali yokujika.Lapho ukhetha isibani esinengxenye yesignali ephuzi ephuzi, udinga ukuthenga isibani esinesibani esikhanyayo, lapho ukhetha isibani esinengxenye yesignali emhlophe, udinga ukuthenga isibani esine-yellow (amber) bulb.
Ukushintshwa kwezibani zemoto kwenziwa ngokulandela imiyalelo yokusebenza nokulungiswa kwemoto.Ngemuva kokushintshwa, kuyadingeka ukulungisa izibani ngokuya ngemiyalelo efanayo.Esimweni esilula, lo msebenzi wenziwa kusetshenziswa isikrini - indiza eqondile enezimpawu lapho izibani ziqondiswa khona, udonga, umnyango wegaraji, ucingo, njll.
Nge-European-style low beam (ene-asymmetric beam), kuyadingeka ukuqinisekisa ukuthi umkhawulo ophezulu wengxenye evundlile yendawo yokukhanya utholakala ngaphansi nje kwesikhungo sezibani.Ukunquma leli banga, ungasebenzisa ifomula elandelayo:
h = H–(14×L×H)/1000000
lapho h okuyibanga ukusuka eksisi yezibani zangaphambili ukuya emngceleni ongenhla wendawo, H ibanga ukusuka endaweni yomgwaqo ukuya phakathi nendawo yezibani, L ibanga ukusuka emotweni ukuya esikrinini, iyunithi yokulinganisa mm.
Ukuze ulungise, kuyadingeka ukubeka imoto ebangeni elingamamitha angu-5-8 ukusuka esikrinini, inani h kufanele lilale ebangeni lika-35-100 mm, kuye ngokuthi ukuphakama kwemoto kanye nendawo yezibani zayo.
Ukuze uthole i-beam ephakeme, kuyadingeka ukuqinisekisa ukuthi isikhungo sezindawo zokukhanya silele cishe isigamu sebanga ukusuka ku-axis optical ye-headlamp kanye nomngcele wendawo yokukhanya ye-low beam.Futhi, izimbazo ze-optical zezibani kufanele ziqondiswe phambili ngokuqinile, ngaphandle kokuphambuka ezinhlangothini.
Ngokukhetha okulungile nokulungiswa kwamalambu, imoto izothola izisetshenziswa zokukhanyisa zekhwalithi ephezulu ezihlangabezana nezidingo zezindinganiso futhi ziqinisekise ukuphepha emgwaqeni uma ushayela ebumnyameni.
