Intlakohlaza yebhaluni.
Iwotshi yasentwasahlobo isetyenziselwa ukudibanisa i-airbag engundoqo (leyo ikwivili lokuqhuba) kwi-harness ye-airbag, eyona nto iyiqhekeza lentambo yokubopha. Ngenxa yokuba ibhegi yomoya ephambili kufuneka ijikeleze kunye nevili lokuqhuba, (inokuthi icingelwe njengentambo yocingo enobude obuthile, ijikelezwe kwi-shaft yokuqhuba isondo, xa ujikeleza kunye nevili lokuqhuba, inokubuyiselwa umva okanye ilimale ngokuqinileyo, kodwa nayo inomda, ukuqinisekisa ukuba ivili lokuqhuba ukuya ngakwesobunxele okanye ngasekunene, intambo yocingo ayikwazi ukutsalwa), ngoko ke intambo yokudibanisa intambo kufuneka ishiye umda. Qinisekisa ukuba ivili lokuqhuba lijikela kwicala ukuya kwindawo elinganiselweyo ngaphandle kokutsalwa. Le ngongoma ekufakeni ingqalelo ekhethekileyo, ngokusemandleni ukuqinisekisa ukuba ikwindawo ephakathi.
Intshayelelo yemveliso
Xa imoto ibetha, inkqubo ye-airbag iyasebenza kakhulu ekukhuseleni ukhuseleko lomqhubi kunye nomkhweli.
Okwangoku, inkqubo ye-airbag ngokubanzi yinkqubo enye ye-airbag yevili lokuqhuba, okanye inkqubo ye-airbag ephindwe kabini. Xa isithuthi esine-airbags ezimbini kunye ne-pretensioner ye-seat belt system iphahlazeka, kungakhathaliseki ukuba isantya sithini, ii-airbags kunye ne-seat belt pretensioner zisebenza ngaxeshanye, okukhokelela kwinkcitho yeengxowa zomoya ngexesha leengozi zesantya esiphantsi, nto leyo eyandisa iindleko zolondolozo kakhulu. .
Inkqubo ye-airbag ephindwe kabini, xa kukho ingozi, inokukhetha ngokuzenzekelayo ukusebenzisa i-pretensioner yebhanti lesihlalo okanye i-pretensioner yebhanti lesihlalo kunye ne-airbag ezimbini ngaxeshanye ngokwesantya kunye nokukhawuleza kwemoto. Ngale ndlela, xa kwenzeka ingozi ngesantya esiphantsi, inkqubo ingasebenzisa kuphela amabhanti ezihlalo ukukhusela umqhubi kunye nokhuseleko lomkhweli, ngaphandle kokuchitha iingxowa zomoya. Ukuba isantya sikhulu kune-30km/h kwingozi, ibhanti lesihlalo kunye nesenzo sebhegi yomoya ngaxeshanye, ukwenzela ukukhusela ukhuseleko lomqhubi kunye nomkhweli.
Umgaqo wokusebenza
Xa imoto ikwingozi yentloko, inkqubo yokulawula i-airbag ibona amandla empembelelo
(i-deceleration) idlula ixabiso elibekiweyo, i-airbag yekhompyuter iqhagamshele kwangoko isekethe yetyhubhu yokuqhuma kombane kwi-inflator, ilumeke indawo yokutshisa kwityhubhu yokudubula yombane, kwaye ilangatye litshisa umgubo wokutshisa kunye nejenereyitha yegesi, ivelisa isixa esikhulu segesi. kwi-0. Ngemizuzwana ye-03, i-air bag ifakwe umoya, isikhwama somoya sandisa ngokukhawuleza, siphuka. ngokusebenzisa igubu lokugquma lokuhombisa kwivili lokuqhuba ukuya kumqhubi kunye nomntu ongaphakathi, ukuze intloko yomqhubi kunye nesifuba somqhubi zicinezelwe kwingxowa yomoya ezaliswe yigesi, ithintele impembelelo kumqhubi kunye nomhlali, kwaye emva koko ikhuphe igesi kwi-gas. ibhegi yomoya.
I-airbag inokusasaza ngokulinganayo amandla empembelelo entloko nasesifubeni, ukukhusela umzimba womkhweli obuthathaka ukuba ube nokungqubana ngqo nomzimba, ukunciphisa kakhulu ukwenzakala. Iingxowa zomoya ziyabakhusela abakhweli xa kukho impembelelo engaphambili, nokuba ibhanti lesihlalo alinxitywanga, ii-airbags ezichasene nokungqubana zisasebenza ngokwaneleyo ukunciphisa ukulimala. Ngokweenkcukacha-manani, xa kukho ukungqubana kwangaphambili nemoto exhotywe ngeengxowa zomoya, izinga lokulimala kwabagibeli lingancitshiswa ukuya kuthi ga kwi-64%, nakwi-80% yalabo bagibeli abanxibanga amabhanti ezihlalo. Ukungqubana kwezihlalo ezisecaleni nezingasemva kusaxhomekeke ekusebenzeni kwebhanti lesitulo.
Ukongezelela, umthamo wokuqhuma kwesikhwama somoya malunga ne-130 decibels kuphela, ephakathi kwendawo enyamezelekayo yomzimba womntu; I-78% yegesi kwi-air bag i-nitrogen, ezinzileyo kwaye ingenabungozi, engenabungozi kumzimba womntu; Umgubo okhutshwe xa uqhushumbo luyipowder yokuthambisa egcina isikhwama somoya kwisimo esongiweyo kwaye singabambeleli kunye, kwaye singenabungozi kumzimba womntu.
Yonke into ilikrele elintlangothi-mbini, kwaye i-airbag nayo inecala layo elingakhuselekanga. Ngokwezibalo, ukuba imoto ihamba nge-60km / h, impembelelo ngokukhawuleza iya kwenza ukuba isithuthi simise ngaphakathi kwemizuzwana ye-0.2, kwaye isikhwama somoya siya kuphuma ngesantya esimalunga ne-300km / h, kwaye umphumo wempembelelo malunga ne-180 kg, okunzima ukuthwala intloko, intamo kunye nezinye iindawo ezisengozini emzimbeni womntu. Ke ngoko, ukuba i-engile kunye namandla e-airbag aphumayo ayilunganga kancinci, inokubangela "intlekele".
Emotweni, ii-sensor ezintathu zihlala zifakela ulwazi lokutshintsha kwesantya kumlawuli we-elektroniki, umlawuli we-elektroniki uhlala ebala, uhlalutya, uthelekisa kunye nabagwebi, kwaye ulungele ukukhupha imiyalelo nangaliphi na ixesha. Xa isantya singaphantsi kwe-30km/h, i-sensor yangaphambili kunye ne-sensor yayo yokhuseleko edibeneyo ngexesha elifanayo ifaka umqondiso wokuphahlazeka kwisilawuli se-elektroniki, kwaye uthumele umyalelo wokukhupha i-detonator yombane ye-pretensioner yesihlalo sesihlalo, ngelixa umqondiso othunyelwe ngumbindi. Uluvo alukwazi ukwenza isilawuli sombane sithumele umyalelo wokuqhumisa isiqhushumbisi sombane sengxowa yomoya. Ngoko ke, kwimeko ye-speed-speed (i-deceleration encinci) ukungqubuzana, nje ukuba i-pre-tensioner idonsa ibhanti lesihlalo ngasemva, kwanele ukukhusela umqhubi kunye nomgibeli ukuba ahlasele ngaphambili.
Kwimeko ye-speed-speed (i-deceleration enkulu), i-sensor yangaphambili kunye ne-sensor ephakathi ngexesha elifanayo ifaka umqondiso wokungqubuzana kumlawuli we-elektroniki, umlawuli we-elektroniki ukhupha umyalelo emva komgwebo okhawulezayo, kwaye uhlambulula i-detonators yombane ngakwesobunxele kwaye i-pretension yasekunene kunye neengxowa zomoya eziphindwe kabini ngaxeshanye. Xa ibhanti lesihlalo litsalwa umva ngokuqinileyo, iingxowa zomoya ezimbini zivula ngaxeshanye ukuze zifunxe amandla empembelelo eyenziwe ngumqhubi kunye nomkhweli ngenxa yokunciphisa isantya esikhulu, ukukhusela ngokufanelekileyo ukhuseleko lwabo.
Xa imoto ingqubana nento emiselweyo phambi kwayo, isantya esihamba ngayo imoto, kokukhona sincipha kakhulu, kwaye kokukhona sifumana amandla ngakumbi inzwa. Ukuba i-pre-set force ye-sensor yangaphambili kunye ne-sensor ephakathi ihlulwe ibe yimida ephezulu kunye nesezantsi, oko kukuthi, isantya sempembelelo echazwe kwangaphambili ye-sensor yangaphambili ingaphantsi kwexabiso eliphantsi lomda we-30km / h, kunye nexabiso elihambelanayo lokuseta. yesivamvo sokhuseleko ikwalixabiso elisezantsi lomda, ngoko isilawuli se-elektroniki sibangela ukuba i-pretensioner yebhanti lesihlalo iqhume xa imoto ibetha ngesantya esiphantsi. Ukuba ixabiso elisetyenzisiweyo le-sensor ephakathi ngumda ophezulu, xa imoto ibetha ngesantya esiphezulu, i-sensor yangaphambili, i-sensor ephakathi kunye ne-sensor yokhuseleko ngaxeshanye ikhupha isignali yokungqubuzana kumlawuli we-elektroniki, kwaye umlawuli we-elektroniki ukhupha wonke umbane. ii-detonator, emva koko ibhanti lesihlalo liyahluzwa kwaye ibhegi yomoya iyavulwa.
Ukususela kungquzulwano, inzwa ithumela umqondiso kumlawuli unquma ukukhupha i-detonator yombane, malunga ne-10ms ixesha. Emva kokuqhawuka, i-generator yegesi ivelisa inani elikhulu le-nitrogen, elikhawuleza lifake isikhwama somoya. Ukususela ekungqubaneni ukuya ekubunjweni kwe-airbag, kwaye emva koko ukuqiniswa kwebhanti yokuhlala, yonke inkqubo ithatha i-30-35ms, ngoko ke umphumo wokukhusela we-airbag system ulungile kakhulu.
Xa i-airbag igqabhuka, ngenxa yesixa esikhulu segesi eveliswa kwi-airbag, uxinzelelo lwe-airbag luyenyuka, olungancedi ukufunxa amandla empembelelo, ngenxa yoko kukho imingxunya emibini yokukhupha igesi ngasemva kwi-airbag yokukhupha umoya. uxinzelelo, olufanelekileyo ekukhuseleni ukhuseleko lomqhubi kunye nomkhweli.
Njengolungiselelo oluncedisayo lokhuseleko lomzimba, abantu bahlawula ingqalelo ngakumbi nangakumbi kuyo. Xa imoto kunye nezithintelo zingqubana, kubizwa ngokuba kukungqubana, umhlali kunye nezixhobo zemoto zingqubuzana, ezibizwa ngokuba yintlupheko yesibini, ibhegi yomoya ekungqubekeni, ungquzulwano lwesibini ngaphambi kokuvulwa ngokukhawuleza kwe-cushion yomoya ogcwele igesi, ngoko ke. ukuba umhlali ngenxa ye-inertia kwaye ahambe "kwi-cushion yomoya" ukunciphisa impembelelo yomhlali kunye nokufunxa amandla empembelelo, ukunciphisa iqondo lokwenzakala umhlali.
Iingxowa zomoya ziye zaphuhliswa ngokukhawuleza kwiminyaka yakutshanje, ixabiso liye lehla kakhulu, kwaye imoto exhotyiswe ngeengxowa zomoya iye yaphuhliswa ukusuka kwixesha elidlulileyo kunye neemoto eziphezulu ukuya kwiimoto eziphakathi kunye neziphantsi. Kwangaxeshanye, ezinye iimoto zixhotyiswe ngeengxowa zomoya zabakhweli kumqolo ongaphambili (oko kukuthi, iinkcukacha ezimbini zeengxowa zomoya), kwaye iingxowa zomoya zabahambi ziyafana nezo zisetyenziswa ngabaqhubi, kodwa umthamo wengxowa yomoya mkhulu kwaye igesi efunekayo Kaninzi. Ukususela ngo-1990, ukusebenza kokhuseleko lwe-airbag kuye kwamkelwa ngokubanzi, kwaye kuthathwa njengesixhobo sokhuseleko lwanamhlanje kunye nomgangatho ophezulu. Ukuqonda umgaqo wokusebenza we-airbag kunye nemicimbi efuna ingqalelo ibaluleke kakhulu kuthi ukuze sizikhusele kangcono, kodwa kumqhubi, ukuqhuba ngokukhuselekileyo ngowokuqala, okungekho sixhobo sokhuseleko oluphezulu sinokutshintshwa.
