Yintoni umsebenzi wesipringi se-airbag?
I-airbag spring isetyenziselwa ukudibanisa i-airbag ephambili (ekwisiteringi) kunye ne-airbag wiring harness. Ngokuyintloko yinxalenye ye-wire harness. Umsebenzi wayo kukusebenza kakuhle ekukhuseleni ukhuseleko lwabakhweli xa kukho ingozi emotweni.
Xa imoto idibana nengozi, inkqubo ye-airbag yokhuseleko isebenza kakuhle kakhulu ekukhuseleni ukhuseleko lwabakhweli.
Inkqubo ye-airbag yokhuseleko ngokubanzi yinkqubo enye ye-airbag yesiteringi okanye inkqubo ye-airbag ezimbini. Izithuthi ezine-airbag ezimbini kunye nenkqubo ye-pre-tensioner yebhanti yesihlalo ziya kuba nee-airbag kunye nee-pre-tensioner zebhanti yesihlalo zisebenza ngaxeshanye xa kukho ingozi, nokuba isantya sithini na. Oku kubangela ukuchithwa kwe-airbag kwiimpembelelo zesantya esiphantsi, okunyusa kakhulu iindleko zokulungisa.
Inkqubo yeengxowa zomoya ezimbini ezinezenzo ezimbini inokukhetha ngokuzenzekelayo ukusebenzisa i-pre-tensioner yebhanti yesihlalo yodwa, okanye zombini i-pre-tensioner yebhanti yesihlalo kunye neengxowa zomoya ezimbini ngaxeshanye xa imoto ifumana impembelelo. Ke ngoko, kwiimpembelelo zesantya esiphantsi, inkqubo ingasebenzisa ibhande lesihlalo yodwa ukukhusela ngokwaneleyo ukhuseleko lwabakhweli, ngaphandle kokuchitha ibhegi yomoya. Ukuba imoto ifumana impembelelo ngesantya esingaphezulu kwe-30 km/h, ibhanti lesihlalo kunye nebhegi yomoya ziya kusebenza ngaxeshanye ukukhusela ukhuseleko lwabakhweli. Xa imoto ifumana ingxabano yangaphambili, inkqubo yolawulo lweengxowa zomoya zokhuseleko ibona amandla empembelelo (ukwehla kwesantya).
Xa ikhompyutha ye-airbag yokhuseleko ibona ukuba amandla ombane adlula ixabiso elimiselweyo, iqhagamshela ngoko nangoko isekethe ye-detonator yombane kwicandelo lokunyuka kwamaxabiso kwaye ivuthele i-ignition medium ngaphakathi kwe-electrical detonator. Ilangatye livuthela i-ignition powder kunye ne-gas generator, ivelisa inani elikhulu legesi, elivuthela i-airbag kwimizuzwana eyi-0.03, nto leyo ebangela ukuba i-airbag yande ngokukhawuleza kwaye igqabhuke kwisiciko sokuhombisa kwivili lokuqhuba kwaye ityhale umqhubi kunye nabakhweli, nto leyo ebangela ukuba iintloko zabo kunye nezifuba zabo zicinezelwe kwi-airbag egcweleyo ukuze ithintele impembelelo. Emva koko, igesi ekwi-airbag iyakhululwa.
I-airbag inokusasaza amandla okubetha ngokulinganayo entloko nasesifubeni, ithintele umzimba wabakhweli obuthathaka ukuba ungangqubani ngqo nomzimba wesithuthi, nto leyo enciphisa kakhulu amathuba okwenzakala. I-airbag yokhuseleko iyasebenza ngokwenene ekukhuseleni abakhweli kwiingozi zangaphambili. Nokuba ibhande lesihlalo alibotshelelwanga, i-airbag yokhuseleko yokulwa nokungqubana isanele ukunciphisa ngempumelelo ukwenzakala. Ngokwezibalo, xa imoto idibana nokungqubana ngaphambili, i-airbag yokhuseleko inokunciphisa izinga lokulimala kwabakhweli ukuya kuthi ga kwi-64%, kwaye kwanama-80% abakhweli abanxibi iibhande zesihlalo. Ngokuphathelele iingozi ezivela ecaleni nakwisihlalo esingasemva, umsebenzi webhande lesihlalo usaxhomekeke ekusebenzeni kwalo.
Ukongeza, umthamo wokuqhuma kwe-airbag umalunga ne-130 decibels, ngaphakathi koluhlu olunokunyanyezelwa ngumzimba womntu; i-78% yegesi ekwi-airbag yi-nitrogen, ezinzileyo kwaye engenabungozi, kwaye ayinabungozi emzimbeni womntu; umgubo okhutshwa ngexesha lokuqhuma ngumgubo wokuthambisa ogcina i-airbag inganamatheli kunye kwimeko egobileyo, kwaye ayinabungozi emzimbeni womntu.
Yonke into inamacala amabini. I-airbag yokhuseleko nayo inecala layo elingakhuselekanga. Ngokwezibalo, ukuba imoto ihamba ngesantya se-60 km/h ize ingqubane ngequbuliso, imoto iya kuma kwimizuzwana eyi-0.2, ngelixa i-airbag iya kuphuma malunga ne-300 km/h, kwaye amandla okubetha avelisiweyo amalunga ne-180 kg, nto leyo enzima kwiindawo zomzimba womntu ezisengozini njengentloko nentamo ukuyithwala. Ke ngoko, ukuba i-engile kunye namandla okukhupha i-airbag aphantsi kancinci, kunokukhokelela "kwintlekele".
Ngexesha lokuqhuba, ii-sensor ezintathu ziqhubeka nokufaka ulwazi malunga notshintsho lwesantya kwi-electronic controller, ebala rhoqo, ihlalutya, ithelekisa, kwaye igwebe, kwaye ikulungele ukukhupha imiyalelo nangaliphi na ixesha. Xa imoto ingqubana ngesantya esingaphantsi kwe-30 km/h, i-sensor yangaphambili kunye ne-sensor yayo yokhuseleko eqhagamshelweyo ngaxeshanye ifaka isignali yokungqubana kwi-electronic controller kwaye ikhuphe umyalelo wokuqhumisa i-seat belt pre-tensioner electric detonator, ngelixa isignali ye-sensor ephakathi ingenakubangela ukuba i-electronic controller ikhuphe umyalelo wokuqhumisa i-airbag electric detonator. Ke ngoko, kwiingqubano zesantya esiphantsi (ezinokunciphisa isantya), lo gama nje i-pre-tensioner itsala i-seat belt ngasemva, kwanele ukukhusela abakhweli ekungqubaneni phambili.
Kwimiba yokungqubana ngesantya esiphezulu (enesantya esikhulu), izinzwa zangaphambili kunye nezinzwa eziphakathi zifaka imiqondiso yokungqubana ngaxeshanye kumlawuli we-elektroniki. Umlawuli we-elektroniki wenza isigqibo ngokukhawuleza aze akhuphe umyalelo, ngaxeshanye eqhumisa ii-pre-tensioners zasekhohlo nasekunene kunye neziqhushumbisi zombane zee-airbags ezimbini. Ngelixa ibhanti yesihlalo itsalwa ngasemva, ezi airbags zimbini zivuleka ngaxeshanye, zifunxa amandla okungqubana aveliswa kukuqunjelwa okukhulu kwabakhweli, zikhusela ngempumelelo ukhuseleko lwabo.
Xa imoto ingqubana nento esisigxina ngaphambili, kokukhona isantya semoto sikhawuleza, kokukhona isantya sincipha, kwaye kokukhona amandla afunyanwa zii-sensors anda. Ukuba amandla amiselweyo ezi-sensors zangaphambili kunye nee-sensors eziphakathi ahlulwe abe yimida ephezulu nesezantsi, oko kukuthi, isantya sokungqubana esimiselweyo sezi-sensors zangaphambili singaphantsi kwexabiso eliphantsi lomda we-30 km/h, kwaye ixabiso elimiselweyo le-sensor yokhuseleko elihambelanayo nalo lixabiso eliphantsi lomda, ngoko kwimeko yokungqubana ngesantya esiphantsi, i-electronic controller isebenzisa kuphela i-pre-tensioner yebhanti yesihlalo. Ixabiso elimiselweyo le-sensor ephakathi ngumda ophezulu, emva koko kwi-high-speed collision, ii-front sensors, ii-central sensors kunye nee-safety sensors ngaxeshanye zikhupha imiqondiso yokungqubana kwi-electronic controller, kwaye i-electronic controller iqhumisa zonke ii-electrical detonators, nto leyo ebangela ukuba ii-seat belts ziqine kwaye ii-airbags zivuleke.
Ukususela ekwenzekeni kwengozi, ii-sensors ezithumela imiqondiso kumlawuli ukuya kwixesha lokugweba kunye nokuqhushumba kwee-detonators zombane, kuthatha malunga ne-10 ms. Emva kokuqhushumba, ijenereyitha yegesi ivelisa inani elikhulu legesi ye-nitrogen, ifutha ngokukhawuleza i-airbag. Ukususela ekwenzekeni kwengozi ukuya ekwakhiweni kwe-airbag, kwaye emva koko iqiniswe ibhanti yesihlalo, yonke inkqubo ithatha i-30-35 ms. Ke ngoko, isiphumo sokukhusela senkqubo ye-airbag silungile kakhulu.
Emva kokuba i-airbag iqhumile, ngenxa yobuninzi begesi ephuma kwi-airbag, uxinzelelo lwe-airbag luyanda, nto leyo engayi kukwazi ukufunxa amandla okungqubana. Ke ngoko, emva kwe-airbag, kukho imingxunya emibini yokukhupha igesi yokunciphisa uxinzelelo, nto leyo eluncedo ekukhuseleni ukhuseleko lwabakhweli.
Njengendlela yokuncedisa ukhuseleko lwesithuthi esingasebenziyo, ifumana ingqalelo yabantu ngakumbi. Xa imoto ingqubana nomqobo, ibizwa ngokuba yi-single collision, kwaye abagibeli bangqubana nezinto zangaphakathi, ezibizwa ngokuba yi-secondary collision. Emva kwe-single collision, i-airbag ivula ngokukhawuleza i-cushion egcwele igesi, ivumela abagibeli ukuba "baphumle kwi-cushion" ngenxa ye-inertia, ngaloo ndlela inciphisa impembelelo kubagibeli kwaye ifunxe amandla okungqubana, inciphisa ubungakanani bokwenzakala kubagibeli.
Ii-airbag zokhuseleko ziphuhlile ngokukhawuleza, kwaye amaxabiso ehla kakhulu. Iimoto ezixhotyiswe ngee-airbag nazo zitshintshe ukusuka kwiimoto eziphakathi ukuya kweziphezulu ukuya kweziphantsi. Kwangaxeshanye, ezinye iimoto zifake ii-airbag zokhuseleko lwabakhweli (oko kukuthi, iinkcukacha ze-airbag zokhuseleko ezimbini), ezifana nee-airbag zokhuseleko lomqhubi, kodwa kuphela ngomthamo omkhulu kunye negesi efunekayo. Ukususela ngeminyaka yoo-1990, ukusebenza kokhuseleko kwee-airbag zokhuseleko kuye kwamkelwa ngokubanzi kwaye kuthathwa njengesixhobo sokhuseleko sanamhlanje nesikumgangatho ophezulu. Ukuqonda umgaqo osebenzayo kunye namanyathelo okhuseleko ee-airbag zokhuseleko kubaluleke kakhulu kuthi ukuze sizikhusele ngcono, kodwa kubaqhubi, ukuqhuba ngokukhuselekileyo yeyona nto iphambili, ekungekho sixhobo sokhuseleko siphambili esinokuyithatha indawo.
