Kwiinjini zokutsha zangaphakathi kunye nebhanti yokuqhuba indlela yokusabalalisa igesi, kuyimfuneko ukuqinisekisa indawo echanekileyo yebhanti kunye nokuzinza kwayo ngexesha lokusebenza.Le misebenzi isonjululwe ngoncedo lwe-roller edlulayo, injongo, ukuyila kunye nokutshintshwa kwayo kuchazwe ngokucacileyo kweli nqaku.
Yintoni irola yokudlula ixesha?
I-bypass (inkxaso, i-intermediate, i-parasitic) i-roller yinto encedisayo ye-belt drive ye-gas distribution mechanism (ixesha), i-pulley ejikelezayo ejikelezayo ye-diameter encinci, apho ibhanti lexesha lijikelezwe kwindawo ethile (okanye amanqaku). ).
Irola yokudlula ixesha isombulula iingxaki ezininzi:
• Ukutshintsha ukuhamba kwebhanti (ukujika kwi-angle efunekayo) ngokuhambelana nendawo yeepuli zecamshaft kunye nezinamathiselo;
• Ukupheliswa kwee-vibrations zamagatsha ebhanti kunye nobude bawo obuninzi;
• Ukuzinziswa kwebhanti lexesha ngexesha lokusebenza, ukuthintela i-resonance phenomena, i-slippage, njl.;
• Ukuncitshiswa kwengxolo kukonke kwindlela yokuhambisa irhasi.
Kwibhanti lexesha lokuqhuba, i-roller enye yodlulayo idla ngokusetyenziswa, kaninzi kancinci, kodwa iinjini ezininzi zale mihla ezinomthamo omncinci azinawo kwaphela la malungu.Ngelo xesha, umntu akufanele adibanise i-roller edlulayo kunye nenye indlela efanayo - i-roller yoxinzelelo.I-tension roller ibonelela ngoxinzelelo oluyimfuneko lwebhanti, luyithintele ekutyibilikeni kunye nokuqhekeka kwe-injini ehambelana nayo, kwaye yenza imisebenzi ye-bypass roller endleleni.Kwixesha elizayo, siza kuthetha nge-bypass rollers.
Iintlobo kunye noyilo lwe-roller yokudlula ixesha
Kungakhathaliseki ukuba luhlobo luni, zonke ii-roller ze-bypass zihlelwe ngendlela efanayo.Isiseko se-roller sithwala, kwindandatho yangaphandle apho i-pulley icinezelwe.I-bearing is radial (ibona kuphela imithwalo ejoliswe kwi-radius), ibhola okanye i-roller, ingaba yinto eqhelekileyo yomqolo omnye okanye ububanzi obuphindwe kabini.Ubuso bokugqibela bokuthwala bunokuvalwa ngentsimbi yentsimbi okanye umkhono ukukhusela ukungcola, uthuli, amanzi kunye nolwelo lobugcisa.I-pulley inesitampu sesinyithi okanye iplastiki eqinile, engenakuhlukaniswa, ngokuxhomekeke kuhlobo lwe-injini, inobubanzi obuhlukeneyo kunye nobubanzi.
Iirola ze-Bypass zinokuba ne-pulley eyenziwe ngezinto ezahlukeneyo:
• Isinyithi - i-aluminium alloy okanye intsimbi;
•Iplastiki.
Umzekelo wokuhamba kwexesha kunye neeroli ezimbini zokudlula ezinobubanzi obuhlukeneyo
Okwangoku, ii-roller zeplastiki zisetyenziswa ngokubanzi, zinexabiso eliphantsi kunezinyithi, ngelixa zibonelela ngengxolo encinci kunye nokunciphisa ubunzima obupheleleyo benkqubo.Iplastiki ixhomekeke ekunxityweni, kodwa isibonelelo seerola zeplastiki zanamhlanje zikhulu, zikholisa ukusebenza lonke ixesha lenkonzo (phakathi kokutshintshwa kwebhanti).
Iirola zensimbi zisetyenziselwa iinjini ezinamandla kunye nezilayishwe kakhulu, apho kubalulekile ukuqinisekisa ukuthembeka kwexesha lokuqhuba kuzo zonke iindlela.
Iirola zinokuba neepuli ezineentlobo ezahlukeneyo zeendawo zokusebenza (iindlela zomdyarho):
• Igudile – indawo yokusebenza igudile, ayinazo naziphi na izitenxo;
• I-Corrugated - indawo esebenzayo ine-longitudinal grooves yobunzulu obunzulu, olu yilo lunciphisa indawo yokudibanisa ye-pulley kunye nebhanti;
• Unamazinyo - indawo esebenzayo inamazinyo anqamlezileyo, le yipulley enamazinyo yokujikeleza okukhululekileyo.
Ngelo xesha, ii-roller ezine-pulley ezigudileyo kunye ne-corrugated zingenziwa zombini zeplastiki kunye nesinyithi, kwaye i-roller enamazinyo ayintsimbi kuphela - intsimbi okanye i-aluminium alloys.
Irola yokudlula enamazinyo
Ii-roller ezigudileyo kunye ne-grooved zifakwe ngendlela yokuba ibhande libagubungele ngasemva (eligudileyo).Ii-roller ezinamazinyo zicwangciswe ngendlela yokuba ibhanti liwagubungele ngokusebenza kwayo (i-toothed) icala.Ukutshintsha i-roller yolunye uhlobo kunye nolunye akuvumelekanga, njengoko oku kutshintsha iimpawu zenkqubo yonke kwaye igcwele ukuphuka kweenjini.
Ekugqibeleni, iipuli ze-roller, kungakhathaliseki ukuba luhlobo luni na, zinokuba neenguqulelo ezimbini:
• Ngaphandle kweekhola zokutyhala;
• Ngeekhola zokutyhala.
Kwimeko yesibini, i-pulley kwelinye okanye kumacala omabini aneekhola zokuphakama ezincinci ezithintela ibhande ukuba lingatyi.Kwiplastiki kunye ne-metal rollers, i-collar, njengomthetho, yenza iyunithi enye kunye ne-pulley, isitampu, iphoswe okanye iguqulwe.Kwi-roller enamazinyo, ikhola kwelinye okanye kumacala omabini angenziwa ngendlela yeendandatho ezikhutshwayo, ezifakwe xa i-roller ifakwe kwi-injini.
Ukufakwa kwe-roller ye-bypass kwi-injini yenziwa ngeendlela ezimbini:
• Ngqo kwibhloko yenjini;
• Ukusebenzisa isibiyeli esahlukileyo.
Kwimeko yokuqala, i-roller kunye nokuthwala kwayo ixhomekeke kwiqonga elinikezelwe ngokukodwa kwi-injini ye-injini kwaye igxininiswe nge-bolt enye (ngokusebenzisa i-washer yokwandisa ububanzi).Kwimeko yesibini, i-roller igxininiswe kwi-bracket, leyo, nayo, ifakwe kwi-injini ye-injini kunye neebholiti ezimbini okanye ngaphezulu.
Ukukhethwa, ukutshintshwa kunye nokusebenza kweerola zokudlula ixesha
I-Bypass rollers igugile ngexesha lokusebenza kwaye idinga ukutshintshwa - lo msebenzi uqhutyelwa ngaxeshanye kunye nokutshintshwa kwebhanti lexesha kunye ne-tension roller.Zonke ezi nxalenye, njengomthetho, zithengiswa kwikiti, ngoko akukho mfuneko yokujonga ngokwahlukileyo kwi-roller kunye ne-fasteners kuyo.Xa uthenga ibhande kunye ne-roller, kufuneka uthathele ingqalelo iingcebiso zomenzi we-injini kwaye ukhethe iinxalenye zeentlobo ezifanelekileyo kunye namanani ekhathalogu.
Kwezinye iimeko, i-roller inokuwohloka okanye ingaphumeleli ngokupheleleyo.Ngokuqhelekileyo, iingxaki zivela kwi-bearing, apho ingxolo engaphandle ibonakala ngexesha lokusebenza kwe-injini.I-roller pulley ibangela iingxaki kancinci kakhulu.Kwimeko nayiphi na into, i-roller kufuneka ithathelwe indawo, kuba oku kufuneka uthenge inxalenye entsha ngokwemiyalelo yomenzi kwaye wenze umsebenzi ngokuhambelana nemiyalelo yokulungiswa nokugcinwa kwale moto.
Ngethuba lokusebenza, i-roller ye-bypass ayifuni ukugcinwa okukhethekileyo, ngokuqhelekileyo le nxalenye isebenza ngokuqhelekileyo kulo lonke ixesha lenkonzo kwaye ayibangeli iingxaki.
Umzimba kunye ne-lens ye-headlamp iphawulwe ngeempawu zayo eziphambili kunye neentlobo zezibane ezinokuthi zifakwe.Ukufakwa kweminye imithombo yokukhanya akuvumelekanga (ngaphandle kwezinto ezinqabileyo), oku kunokutshintsha iimpawu zokukhanya, kwaye ngenxa yoko, isithuthi asiyi kudlula ukuhlolwa.
Imiba yokukhetha, ukutshintshwa kunye nokusebenza kwezibane zemoto
Ukukhetha i-optics entsha, kuyimfuneko ukuqwalasela ukuyila, iimpawu kunye neempawu zeemveliso ezindala, ngokufanelekileyo kufuneka uthenge ukukhanya kwentloko yemodeli efanayo.Ukuba sithetha ngezibane zenkungu okanye izibane zokukhangela kunye nezibane ezazingekho emotweni, ke apha kufuneka uthathele ingqalelo ukuba kunokwenzeka ukufaka ezi zixhobo kwimoto (ubukho beebakaki ezifanelekileyo, njl.) kunye neempawu zabo.
Ingqwalasela ekhethekileyo kufuneka ihlawulwe ekukhethweni kwezibane.Namhlanje, zidla ngokunikezelwa kwiinguqulelo ezimbini - kunye nenxalenye ecacileyo (emhlophe) kunye nephuzi yesignali yokujika.Xa ukhetha i-headlight kunye ne-yellow turn sign segment, kufuneka uthenge isibane ngebhalbhu ecacileyo, xa ukhetha isibane esinecandelo elimhlophe elijikayo, kufuneka uthenge isibane ngebhalbhu ephuzi (amber).
Ukutshintshwa kwezibane zentloko kuqhutyelwa ngokwemiyalelo yokusebenza kunye nokulungiswa kwemoto.Emva kokutshintshwa, kuyimfuneko ukulungelelanisa izibane zentloko ngokwemiyalelo efanayo.Kwimeko elula, lo msebenzi wenziwa usebenzisa isikrini - indiza ethe nkqo eneempawu apho izibane ziqondiswe khona, udonga, umnyango wegaraji, ucingo, njl njl. unokusebenza njengesikrini.
Kwi-European-style beam low (kunye ne-asymmetric beam), kuyimfuneko ukuqinisekisa ukuba umda ophezulu wecala elithe tye lendawo yokukhanya ibekwe ngaphantsi nje kombindi wezibane.Ukumisela lo mgama, ungasebenzisa le fomula ilandelayo:
h = H–(14×L×H)/1000000
apho h ngumgama ukusuka kwi-axis yezibane ukuya kumda ophezulu wendawo, H ngumgama ukusuka kwindawo yendlela ukuya kumbindi wezibane, L ngumgama ukusuka kwimoto ukuya kwisikrini, iyunithi yokulinganisa mm.
Ukulungelelaniswa, kuyimfuneko ukubeka imoto kumgama weemitha ezi-5-8 ukusuka kwisikrini, ixabiso h kufuneka lilale kuluhlu lwe-35-100 mm, kuxhomekeke kubude bemoto kunye nendawo yezibane zayo.
Kwi-beam ephezulu, kuyimfuneko ukuqinisekisa ukuba iziko leendawo zokukhanya zilele malunga nesiqingatha somgama ukusuka kwi-axis ye-optical ye-headlamp kunye nomda wendawo yokukhanya ephantsi.Kwakhona, i-axes optical of the headlights kufuneka iqondiswe ngokuthe ngqo phambili, ngaphandle kokuphambuka emacaleni.
Ngokukhetha okufanelekileyo kunye nokulungiswa kwezibane, imoto iya kufumana izixhobo zokukhanyisa ezikumgangatho ophezulu ezihlangabezana neemfuno zemigangatho kwaye ziqinisekise ukhuseleko endleleni xa uqhuba ebumnyameni.
