Iisetyenzisi zedrafti zendabuko azange zitshintshe yonke into ekhulwini lokugqibela, ngoko i-teknoloji ye-brake-wire-wire igxininisa utshintsho olwandle olwenziwa ngabakwa-automakers kunye noluntu ngokubanzi baye banqwenela ukuwamkela. Nangona iinkqubo zemveli zemizila yamanzi zineengxaki zabo, kukho into eqinisekisayo ekunxibelelweni ngokuthe ngqo, emzimbeni phakathi kweenyawo zakho kunye neenqwelo zokuqhawula okanye izicathulo ezisezikhoneni ezine zesithuthi sakho. Ikhefu le-brake-by-wire edibeneyo, oko kutheni iteknoloji ibonakala ngathi iyingozi kakhulu kunokuba ilawulwe yi-electronic throttle control okanye i- steer-wire-wire .
Uhlobo olududuzayo lwee-Brake Drivers
Indlela yokusetyenziswa kwezixhobo zomdabu eziqhelekileyo ezisebenzele amashumi eminyaka kukuba ukunyathela kwi-pedal pedal kudala uxinzelelo lwama-hydraulic olusetyenziselwa ukuvula izicathulo zetrake okanye ipads. Kwiinkqubo ezindala, i-pedal yenza ngokuthe ngqo kwi-hydraulic component eyaziwa njenge-cylinder master. Kwiinkqubo zanamhlanje, i-booster bhesterster, ngokuqhelekileyo ixhaswe nge-vacuum, iphakamisa amandla e-pedal kwaye yenza kube lula ukuwaphula.
Xa i-cylinder inkosi isebenze, ivelisa uxinzelelo lwama-hydraulic kwimigca yokunqakraza. Olu xinzelelo lwenziwa emva koko kwiingcongolo zekhoboka ezikhoyo kwivili ngalinye, elithintela i-rotor phakathi kweepakeli ze-brake okanye ucinezele izicathulo zokuwazisa ngaphandle ukuya kwingqungquthela.
Iinkqubo zamanqwanqwa zokuhlambulula amanzi zanamhlanje ziyinkimbinkimbi kunokuba, kodwa zisasebenza kumgaqo oqhelekileyo. I-hydraulic okanye i-vacuum boosters iyanciphisa umlinganiselo wamandla umqhubi kufuneka asebenzise, kwaye ubuchwepheshe ezifana ne- anti-lock lock kunye neenkqubo zokulawula ukulandelelana ziyakwazi ukuvula ngokuzenzekelayo okanye ukukhulula iibhuleki.
Amabhuleki kagesi kunye ne-electro-hydraulic asetyenziswa ngokuqhelekileyo kwiendlela. Ekubeni ama-trailers sele sele anxibelelwano lwamagetsi okukhanyisa izibane kwaye aguqule umqondiso, yinto elula ukucoca kwi-electro-hydraulic master cylinder okanye i-actuators kagesi. Ubuchwephesha obufanayo bufumaneka kwii-OEMs ezimbalwa, kodwa uhlobo olukhuselekile lokukhusela lweebhuleki luye lwaphumela kwisibambiso sezimoto ezihlala zinganqikazi ukufumana iteknoloji ye-brake-wire-naliphi na amandla okwenene.
I-Brake-Hydraulic Brakes Stop Mfutshane
Isiqhamo sangoku sesebenzisiweyo se-brake-wire-usetyenziso lwe-electro-hydraulic model engacwangciswanga ngokupheleleyo. Ezi nkqubo zineendlela zokusetyenziswa kwamanzi, kodwa umqhubi akayi kusebenza ngokuthe ngqo kwi-cylinder ye-master ngokucinezela kwi-pedal pedake. Endaweni yoko, i-master cylinder isebenze ngumbane okanye umpompo olawulwa yunithi yokulawula.
Xa i-pedake-pedal ixinzelelwe kwinkqubo ye-electro-hydraulic system, i-unit control isebenzisa ulwazi ukusuka kwininzi yeenjini ukucacisa ukuba i-braking ishukumisa kangakanani ivili ngalinye. Inkqubo inokusetyenzisa umlinganiselo ofanelekileyo wokunyanzeliswa kwe-hydraulic kwi-caliper nganye.
Olunye uqobo oluphambili phakathi kwee-electro-hydraulic kunye nemveli yendlela yokuhlamba i-hydraulic system (freraulic freake system systems). Iinkqubo zokuxoka kwee-electro-hydraulic ziqhuba ngokuphantsi kweengcinezelo eziphezulu kakhulu kuneenkqubo zendabuko. Iibhululo ze-Hydraulic zisebenza malunga ne-800 PSI phantsi kweemeko eziqhelekileyo zokuqhuba, ngelixa i-Sensotronic i-electro-hydraulic systems igcina iingcinezelo phakathi kwe-2,000 ne-2,300 i-PSI.
Iinkqubo ze-Electromechanical Systems Ngokuqinisekileyo u-Brake-Wire-Wire
Nangona imifanekiso yokuvelisa isasebenzisa iinkqubo ze-electro-hydraulic systems, iteknoloji ye-brake-wire-wire igxininise imithombo yamanzi. Le teknoloji ayizange iboniswe kuyo nayiphina imodeli yokuvelisa ngenxa yohlobo olukhuselekile lokukhusela, kodwa luye lwafumana uphando olunzulu kunye novavanyo.
Ngokungafani namabhuleki e-electro-hydraulic, zonke iinqununu kwi-electro-mechanical system zisekhompyutheni. Abaqhankqalazi baneendawo zokusebenzisa iikhomputha zecomputer, kwaye zonke izinto zilawulwa ngqo ngunithi yokulawula endaweni ye-cylinder enkulu. Ezi nkqubo zifuna nenani leehadi eziziongezelelweyo, kuquka ukushisa, amandla okuphosa, kunye neenjini zesikhombisi se-actuator kwi-caliper nganye.
Iibhuleki ze-Electromechanical nazo ziquka amanxibelelwano anzima anxibelelwano ukususela kwinqanaba ngalinye lokufumana izixhobo ezininzi zeedatha ukwenzela ukuvelisa umlinganiselo ofanelekileyo wokuxhatshazwa kwamandla. Kwaye ngenxa yohlobo olukhuselekile lwezo nkqubo, kufuneka kubekho ibhasi elincinci, elisekondari ukuhambisa idatha eluhlaza kubalindi.
I-Sticky yoKhuseleko lwe-Brake-by-Wire Technology
Nangona i-hydro-electric kunye ne-electromechanical systems brake zikwazi ukukhuseleka kuneenkqubo zendabuko, ngenxa yokunxibelelana okukhulu kunye ne-ABS, ESC kunye nezinye ezobuchwepheshe obufanayo, ukuxhalaba kwezokukhusela kubakho. Iisetyenziselwano zentsimbi ze-brake ziyakwazi kwaye ziyahluleka, kodwa ukulahlekelwa ngengozi yomsindo wokuxinzelela kwamanzi kuya kutshabalalisa ngokupheleleyo umqhubi wekhono lokuyeka okanye ukucotha, ngelixa iinkqubo ezinokwakheka kwe-electromechanical zincinci zininzi ezininzi zokungaphumeleli.
Izidingo zeFailovers, kunye nezinye izikhokelo zokuphuhliswa kweenkqubo ezikhuselekile zokukhusela ezifana ne-brake-by-wire, zilawulwa yimigangatho yokhuseleko yomsebenzi njenge-ISO 26262
Ngubani ohambisa i-Brake-by-Wire Technology?
I-Redundancy kunye neenkqubo ezikwazi ukusebenza kunye nexabiso elincinci lwedatha ekugqibeleni liza kugcina ukwenziwa kweteknoloji ye-electromechanical i-brake-wire-ekhuselekileyo ngokwaneleyo ukwenzela ukwamkelwa komntu wonke, kodwa kweli nqanaba kuphela ii-OEMs ziye zazama iindlela ze-electro-hydraulic systems.
IToyota yaqala ukufaka inkqubo yokuqhuma i-electro-hydraulic system ngonyaka ka-2001 kwi-Estima Hybrid yayo, kwaye ukuhluka kobuchwepheshe be-Brake (Controls Brake) (ECB) buye lwafumaneka ukususela ngoko. I-teknoloji yokuqala yabonakala e-US ngonyaka we-2005 ngomzekelo weLexus RX 400h.
Umzekelo apho ubuchwepheshe bentambo-yecingo obubhekene nokungaphumeleli ukuqaliswa xa uMercedes-Benz atshayile inkqubo yayo yeSensotronic Brake Control (SBC), eyayisetyenziswe ngonyaka we-2001. Le nkqubo yachithwa ngokusemthethweni ngo-2006 emva kokukhumbula okuxabayo ngo-2004, kunye no-Mercedes besithi iya kunika ukusebenza okufanayo kwenkqubo ye-SBC nge-system ye-brake hydraulic system.
