Iyini i-accelerator pedal assembly
I-automobile accelerator pedal assembly iyingxenye ebalulekile yemoto, esetshenziswa kakhulu ukulawula ukuvuleka kwenjini, ukuze kulungiswe amandla enjini. I-accelerator pedal assembly ngokuvamile iqukethe izingxenye eziyinhloko ezilandelayo:
I-Accelerator pedal body : Lena ingxenye engokoqobo efana ne-gas pedal yendabuko, ngokuvamile eyenziwa ngensimbi noma ezinye izinto ezihlala isikhathi eside. Umshayeli angakwazi ukulawula ukusheshisa kwemoto ngokucindezela phansi noma ngokudedela i-pedal .
inzwa : Inzwa encane efakwe kumzimba we-accelerator pedal ukuze kutholwe inani nesiqondiso samandla asetshenziswa umshayeli ku-pedal. Lolu lwazi luthunyelwa ophikweni lokulawula ngogesi lwemoto.
I-Electronic Control Unit : Lobu ubuchopho bemoto, obunomthwalo wemfanelo wokuhumusha idatha yokufaka evela ezinzwa nokuyiguqula ibe imiyalo yokulawula injini. I-ECU ingaphinda icubungule idatha evela kwezinye izinzwa njengezinzwa zesivinini, izinzwa ze-oxygen, njll., ukuze inike amandla izindlela zokushayela eziyinkimbinkimbi nemisebenzi yokulawula.
i-actuator/umshayeli : injini encane noma idivayisi yomoya ethola imiyalelo evela ku-ECU futhi ilungise ukuvuleka kwe-throttle njengoba kudingeka. Lokhu kungenziwa ngokushintsha amandla okulayisha kuqala e-throttle spring noma ngokusebenzisa idivayisi ye-pneumatic.
i-throttle : insimbi encane encane etholakala endaweni yokungena injini okuvuleka kwayo kungalungiswa ngokuvumelana nemiyalelo ye-ECU. Lapho i-throttle ivulekile, kungena umoya omningi enjinini, okwenza injini ishise uphethiloli owengeziwe futhi ikhiqize amandla engeziwe.
Lezi zingxenye zisebenza ndawonye ukuze zinike amandla i-accelerator pedal ye-elekthronikhi ukuthi ilawule ngokunembile ukusheshisa kwemoto ngenkathi inikeza ukusebenza kahle kukaphethiloli nokusebenza kokushayela.
Umgomo wokusebenza wokuhlanganisa i-automobile accelerator pedal assembly ikakhulukazi uhlanganisa izindlela ezimbili zokusebenza zemishini yesimanje neyesimanje.
Isimiso sokusebenza somhlangano we-accelerator we-Mechanical pedal
Emotweni yendabuko, i-accelerator pedal ixhunywe ku-throttle valve yenjini ngentambo yokudonsa noma induku yokudonsa. Lapho umshayeli enyathela i-accelerator pedal, ukuvuleka kwe-throttle kulawulwa ngokuqondile, ngaleyo ndlela kulawula ukuphuma kwamandla enjini. Lokhu kuxhuma kwemishini kulula futhi kuqondile, kodwa isimo sekhebula le-throttle noma induku kudingeka sihlolwe futhi sigcinwe njalo ukuze kuqinisekiswe ukusebenza kwayo okuvamile.
Isimiso sokusebenza somhlangano wesimanje we-electronic accelerator pedal
Izimoto zesimanje ziya ngokuya zisebenzisa ama-electronic throttle systems. Inzwa yokufuduka ifakwe ku-accelerator pedal ye-accelerator kagesi. Lapho umshayeli enyathela i-accelerator pedal, inzwa yokufuduka izoqoqa ushintsho lokuvula lwe-pedal kanye nolwazi lokusheshisa. Le datha idluliselwa enjini yokulawula i-electronic unit, ehlulela inhloso yokushayela yomshayeli ngokusho kwe-algorithm eyakhelwe ngaphakathi, bese ithumela isignali yokulawula ehambisanayo ku-motor control ye-throttle injini, ngaleyo ndlela ilawula ukuphuma kwamandla enjini. Uhlelo lwe-electronic throttle aluthuthukisi nje ukunemba kokulawula amandla, kodwa futhi lwandisa ukwethembeka kwesistimu nokunethezeka kokushayela.
Indlela inzwa yokuma kwe-accelerator pedal isebenza ngayo
Inzwa ye-accelerator pedal position ezimotweni zesimanje ivamise ukusebenzisa into yeHholo engathinteki ebekwe engalweni ye-accelerator pedal. Lapho i-accelerator pedal ihamba, inzwa ithola ukuhamba kwe-pedal bese ikhipha isignali ye-voltage ehambisana nokuhamba kwe-pedal. Ngokusekelwe kule siginali ye-voltage, i-ECU ibala inani likaphethiloli elijovwe, ngaleyo ndlela izuze ukulawulwa okunembile kwenjini. Le nzwa engathinteki ibonakala ngokwethembeka okuphezulu nempilo ende ukuze kuqinisekiswe ukusebenza okuzinzile kwesistimu.
