Indibano ye-Automobile Vacuum Booster: I-Core Defender kunye ne-Fault Response kwi-Brake System
"Kwintsapho" yenkqubo yeebhuleki zeemoto, i-vacuum booster assembly ithathwa njengelungu eliphantsi kodwa elibalulekileyo. Ifana nomntu onamandla ofihliweyo ngasemva kwemifanekiso, ekhusela ngokuzolileyo yonke imisebenzi yeebhuleki zomqhubi. Ayinciphisi nje kuphela umthwalo womzimba kumqhubi kodwa ikwakha umgca wokhuselo obalulekileyo wokhuseleko lokuqhuba.
Umsebenzi oyintloko wendibano ye-vacuum booster
Ukuqhobosha okusebenzayo, umthwalo wokusebenza ophantsi Umsebenzi ocacileyo we-vacuum booster assembly kukufezekisa ukuqhobosha okusebenzayo. Isebenzisa i-50 - 80 kPa yoxinzelelo olune-vacuum oluvela kwi-manifold ye-intake yenjini okanye ipompo ye-vacuum yombane. Xa umqhubi enyathela i-brake pedal, i-diaphragm yegumbi le-servo yenza umahluko woxinzelelo kumacala omabini, ngaloo ndlela ivelisa i-600 - 1200 N thrust, ebekwe phezu koxinzelelo lweenyawo zomqhubi, inciphisa amandla e-pedal ngama-40% - 70%. Umzekelo, umqhubi ufuna kuphela i-10 kg yamandla eenyawo ukuze afezekise i-30 kg yempembelelo yokwenyani yokuqhobosha, enokuba luncedo ngakumbi kubaqhubi abangabasetyhini okanye ababuthathaka ngokwasemzimbeni, nto leyo enciphisa ngokufanelekileyo ukudinwa ngokwasemzimbeni ngexesha lokuqhuba ixesha elide.
Isiqinisekiso sokhuseleko lokungaphumeleli, ukusinda kwiimeko ezinzima kakhulu. Kwimeko yokusilela kwenkqubo ye-vacuum, umsebenzi wesiqinisekiso sokhuseleko lokungaphumeleli kwendibano ye-vacuum booster uya kusebenza. Ngeli xesha, intonga yokutyhala yevalvu yokulawula iya kutyhala ngqo intonga yokutyhala yesilinda ephambili kwisakhiwo soomatshini. Nangona amandla afunekayo kwi-brake pedal aya kwanda kakhulu ukusuka kwi-80 - 150 N eqhelekileyo ukuya kwi-300 - 500 N, amandla okuqhobosha asisiseko asagciniwe, ngokuhambelana nomgangatho wokhuseleko wesizwe onyanzelekileyo (GB 21670 - 2008). Olu yilo luqinisekisa ukuba isithuthi sinokugcina amandla okuqhobosha asisiseko kwiimeko ezinzima, okunika abaqhubi ixesha elibalulekileyo lokuphatha ngokukhawuleza.
Ulawulo lokuphendula ngexesha langempela, ukuchaneka okuphuculweyo kokubhuleka. Isebenzisa isakhiwo seevalvu ezimbini, esinokugqiba ukutshintsha kwendlela yokubhuleka ngaphakathi kwemizuzwana eyi-0.1 - 0.3. Ukulibaziseka koncedo lokubhuleka kuphantsi kunomda oqhelekileyo wamazwe ngamazwe we-200 ms, ukuqinisekisa impendulo ekhawulezileyo yokusebenza kokubhuleka. Idiski yangaphakathi yerabha yokuthintela ingadlulisela i-85% - 95% yamandla e-servo kwaye ngaxeshanye inike umqhubi ingxelo yamandla okuphehla, inceda umqhubi ukuba aqonde ngokuchanekileyo amandla okubhuleka, iphucule ukuchaneka kokusebenza kokubhuleka. Kwiimodeli zezithuthi zombane, ipompo yokufunxa yombane efakiweyo ikwanokuhlangabezana neemfuno ezimbini zenkqubo yokubuyisela amandla kunye nenkqubo yokubhuleka yendabuko, iphucula ukusebenza kokubhuleka kwesithuthi kunye nokusebenza kakuhle kwamandla.
Iimpazamo eziqhelekileyo kunye nezisombululo zendibano ye-vacuum booster
Ipedali yebhuleki iba lukhuni, ukumelana nokubhuleka kwanda Oku kukubonakaliswa kwempazamo eqhelekileyo, okuhlala kubonisa ingxaki yokutywina kwinkqubo yokutywina, mhlawumbi ebangelwa kukuvuza kombhobho wevacuum, ukuguga kunye nomsesane wokutywina wepompo yevacuum owonakeleyo, njl. Xa oku kusenzeka, umqhubi uya kuziva ukuba ukuqhobosha kufana nokunyathela "amatye aqinileyo", afuna umgudu ongakumbi. Isisombululo kukuya ngokukhawuleza kwiziko lokulungisa eliyingcali ukuze kujongwe ukutywinwa kombhobho wevacuum, umpompo wevacuum, kunye ne-booster ngokwayo, kwaye kutshintshwe umsesane wokutywina owonakeleyo okanye kulungiswe umbhobho ovuzayo.
Ukubuya okungaqhelekanga kwepedali yebrake Ukuba ipedali yebrake ibuya kancinci okanye ayibuyi emva kokuba icinezelwe, kusenokwenzeka ukuba kukho ukungasebenzi kakuhle koomatshini kwisakhiwo sangaphakathi se-booster, njengokuxinana kwecandelo okanye umonakalo. Oku kuya kuchaphazela ukuseta kwakhona okuqhelekileyo kwenkqubo yebrake kwaye kwandise umngcipheko wokuqhuba. Ngexesha lokulungiswa, i-booster assembly kufuneka ihlulwe ukuze kuhlolwe iindawo zangaphakathi ze-mechanical, kuthanjiswe izinto ezixineneyo okanye kutshintshwe iindawo ezonakeleyo.
Umgama owandisiweyo wokubhuleka, ukusebenza okunciphileyo kokubhuleka Xa indibano ye-vacuum booster ingaphumeleli ukunika uncedo olwaneleyo, isiphumo sokubhuleka siya kuncipha kakhulu, kwaye umgama wokubhuleka uya kwanda kakhulu. Impazamo inokubangelwa kukusilela kwe-motor ye-vacuum pump okanye i-electronic delay module, ukungaphumeleli kwe-pressure switch okanye umgca we-pressure switch, njl. Abasebenzi bokulungisa banokufunda ikhowudi yempazamo kunye nokuhamba kwedatha ngokudibanisa isixhobo sokuxilonga ukujonga imeko yokusebenza, ixabiso loxinzelelo lwangoku olusebenzayo kunye nenkqubo ye-vacuum ye-vacuum pump, bamisele indawo ethile yempazamo kwaye batshintshe izinto ezihambelanayo. Ingxolo ye-brake kunye nokushukuma kwesithuthi Ngexesha lenkqubo yokubhuleka, ukuba kukho ingxolo engaqhelekanga okanye ukushukuma kwesithuthi, kusenokuba kungenxa yokuguguleka kwezixhobo zangaphakathi ze-booster okanye ukungasebenzi kakuhle kwe-vacuum booster, okubangela amandla okubhuleka angalinganiyo. Ngeli xesha, kuyimfuneko ukujonga ngokukhawuleza ukuguguleka kweendawo zangaphakathi ze-booster, ukutshintsha iindawo eziguguleke kakhulu, kunye nokujonga ukuba kukho ukuvuza komoya kwinkqubo ye-vacuum ukuqinisekisa amandla okubhuleka afanayo nazinzileyo.
Nangona i-vacuum booster assembly ifihliwe ngaphakathi kwisithuthi, inxulumene ngokuthe ngqo nokhuseleko lokuqhuba kunye namava okuqhuba. Xa abaqhubi besebenzisa imoto yonke imihla, kufuneka banikele ingqalelo kwiimpawu ezingaqhelekanga zenkqubo yokuqhobosha kwaye bahlole rhoqo kwaye bagcine i-vacuum booster assembly. Ukuba kukho naziphi na iingxaki ezifunyenweyo, kufuneka zijongwane nazo ngokukhawuleza, ukuze le "backing guard" ihlale isebenza kakuhle kwaye iqinisekise ukhuseleko lohambo ngalunye.
