Amabhuleki e-Ceramic awuhlobo lwe-brake pad ehlanganisa i-mineral fibre, i-aramid fibre kanye ne-ceramic fiber (ngoba i-fiber yensimbi ingagqwala, ikhiqize umsindo nothuli, ngakho-ke ayikwazi ukuhlangabezana nezidingo zokwakheka kohlobo lwe-ceramic).
Abathengi abaningi bazoqale benze iphutha le-ceramic ngokuthi yenziwe nge-ceramic, kodwa empeleni, amabhuleki e-ceramic enziwe ngomgomo wezinsimbi zobumba kunezinsimbi ezingezona ezensimbi.Kuleli zinga lokushisa eliphakeme, ingaphezulu lephedi yebhuleki lizokwenziwa ngendlela efanayo yensimbi-ceramic, ukuze iphedi yebhuleki ibe nokuzinza okuhle kulokhu kushisa.Amabhuleki endabuko awakhiqizi ukusabela kwe-sintering kuleli zinga lokushisa, futhi ukwanda okubukhali kwezinga lokushisa elingaphezulu kungabangela ukuthi impahla engaphezulu incibilike noma ikhiphe umcamelo womoya, okungabangela ukwehla okukhulu kokusebenza kwamabhuleki ngemva kokubhuleka okuqhubekayo noma ukulahlekelwa okuphelele. wokubhuleka.
Amabhuleki e-Ceramic anezinzuzo ezilandelayo ngaphezu kwezinye izinhlobo zamabhuleki.
(1) Umehluko omkhulu phakathi kwamabhuleki e-ceramic nama-brake pads ukungabikho kwensimbi.Kumabhuleki endabuko, insimbi iyimpahla eyinhloko eyenza ukungqubuzana, okunamandla amakhulu okubhuleka, kodwa ejwayele ukuguga nomsindo.Uma kufakwa amabhuleki e-ceramic, ngeke kube khona ukuxabana okungavamile (okungukuthi umsindo wokuklwebha) ngesikhathi sokushayela okuvamile.Ngenxa yokuthi amabhuleki e-ceramic awanazo izingxenye zensimbi, umsindo ohlabayo wamabhuleki ensimbi agudlanayo (okungukuthi amabhuleki nama-brake disc) uyagwenywa.
(2) I-coefficient eqinile yokungqubuzana.I-friction coefficient iyinkomba yokusebenza ebaluleke kakhulu yanoma iyiphi impahla yokushayisana, ehlobene nekhono elihle noma elibi lokubhuleka lama-brake pads.Enqubweni yokubhuleka ngenxa yokushisa okukhiqizwe ukungqubuzana, izinga lokushisa elisebenzayo liyakhula, izinto ezivamile zokungqubuzana kwe-brake pad ngezinga lokushisa, i-coefficient of friction iqala ukwehla.Ekusetshenzisweni kwangempela, kuzonciphisa amandla okushayisana, ngaleyo ndlela kunciphise umphumela wokubhuleka.Impahla yokushayisana yamaphedi amabhuleki ajwayelekile ayivuthiwe, futhi i-coefficient yokushayisana iphezulu kakhulu okubangela izici ezingaphephile ezifana nokulahlekelwa indlela ngesikhathi sokubhuleka, amaphedi ashile nama-brake discs aklwebhekile.Ngisho noma izinga lokushisa le-brake disc liphezulu kakhulu njenge-degrees angu-650, i-coefficient ye-friction ye-ceramic brake pads isazungeze u-0.45-0.55, engaqinisekisa ukuthi imoto inokusebenza kahle kokubhuleka.
(3) I-Ceramic inokuzinza okungcono kwe-thermal kanye ne-conductivity ephansi yokushisa, nokumelana okuhle kokugqoka.Izinga lokushisa lokusebenzisa isikhathi eside ngamadigri ayi-1000, lesi sici senza i-ceramic ingafaneleka ezinhlobonhlobo zezinto ezisebenza kahle zokubhuleka, izidingo zokusebenza okuphezulu, zingahlangabezana ne-brake pad high-speed, ukuphepha, ukumelana nokugqoka okuphezulu nezinye izidingo zobuchwepheshe.
(4) Inamandla amahle emishini nezinto ezibonakalayo.Ingakwazi ukumelana nokucindezela okukhulu namandla okugunda.Imikhiqizo yezinto ezibonakalayo ze-Friction emhlanganweni ngaphambi kokusetshenziswa, kunesidingo sokumba, ukuhlanganisa nokunye ukucutshungulwa komshini, ukuze wenze umhlangano we-brake pad.Ngakho-ke, izinto zokungqubuzana kufanele zibe namandla anele okusebenza ukuze kuqinisekiswe ukuthi ukucubungula noma ukusetshenziswa kwenqubo akubonakali kuphuka futhi kuhlakazeke.
(5) Yiba nempahla ebolile ephansi kakhulu.
(6) Thuthukisa ukusebenza kwamabhuleki pads.Ngenxa yokushabalaliswa kokushisa okusheshayo kwezinto zobumba, isetshenziswa ekwenzeni amabhuleki, futhi i-coefficient yayo yokushayisana iphakeme kunaleyo yama-brake pads ensimbi.
(7) Ukuphepha.Amabhuleki ama-brake pad akhiqiza izinga lokushisa eliphezulu ngokushesha uma ubhuleka, ikakhulukazi uma uhamba ngesivinini esiphezulu noma uma ubhuleka ezimeni eziphuthumayo.Esimweni sokushisa okuphezulu, i-coefficient ye-friction yamaphedi okukhuhlana izokwehla, okubizwa ngokuthi i-thermal recession.Amabhuleki avamile ukuwohloka okushisayo kwezinga lokushisa eliphansi, eliphezulu kanye nokubhuleka okuphuthumayo lapho izinga lokushisa le-brake fluid likhuphuka ukuze ukubambezeleka kwebhuleki, noma ngisho nokulahlekelwa yisici sokuphepha somphumela wokubhuleka kube phansi.
(8) induduzo.Phakathi kwezinkomba zokunethezeka, abanikazi bavame ukukhathazeka kakhulu ngomsindo wama-brake pads, empeleni, umsindo uyinkinga yesikhathi eside engakwazi ukuxazululwa ngama-brake pads ajwayelekile.Umsindo udalwa ukungqubuzana okungavamile phakathi kwe-friction pad kanye ne-friction disc, futhi izizathu zokukhiqiza kwayo ziyinkimbinkimbi kakhulu, njenge-braking force, izinga lokushisa le-brake disc, isivinini semoto kanye nezimo zezulu. zonke izizathu ezingenzeka zomsindo.
(9) Izici zezinto ezibonakalayo ezinhle kakhulu.Amabhuleki e-Ceramic asebenzisa izinhlayiya ezinkulu ze-graphite/ithusi/i-ceramic ethuthukisiwe (okungeyona i-asbestos) kanye ne-semi-metal nezinye izinto zobuchwepheshe obuphezulu ezinokumelana nokushisa okuphezulu, ukumelana nokugqokwa, ukuzinza kwamabhuleki, ukulungisa i-brake disc yokulimala, ukuvikelwa kwemvelo, akukho msindo omude. impilo yesevisi kanye nezinye izinzuzo, ukunqoba impahla ye-brake pad yendabuko kanye nokukhubazeka kwenqubo kuyinkimbinkimbi kunazo zonke yamabhuleki e-ceramic yamazwe ngamazwe athuthuke kakhulu.Ngaphezu kwalokho, okuqukethwe okuphansi kwebhola le-ceramic slag kanye nokuthuthukiswa okuhle nakho kunganciphisa ukuguga kwamapheya nomsindo wama-brake pads.
(10) Impilo ende yesevisi.Impilo yesevisi iyinkomba yokukhathazeka okukhulu.Impilo yesevisi yamabhuleki ajwayelekile ingaphansi kuka-60,000 km, kanti impilo yesevisi yamabhuleki e-ceramic ingaphezu kuka-100,000 km.Lokhu kungenxa yokuthi amabhuleki e-ceramic asebenzisa ifomula eyingqayizivele yezinhlobo ezi-1 kuye kwezi-2 kuphela ze-electrostatic powder, ezinye izinto zokwakha izinto ezingezona ezimile, ukuze impushana izothathwa umoya ngokuhamba kwemoto, futhi ngeke inamathele. kwihabhu lamasondo ukuze kuthinte ubuhle.Isikhathi sokuphila se-ceramic singaphezulu kuka-50% ngaphezu kwalezo ezijwayelekile ze-semi-metal.Ngemuva kokusebenzisa amabhuleki e-ceramic, angeke kube khona izisele zokuklwebha (okungukuthi, ukuklwebheka) kuma-brake discs, okunweba impilo yesevisi yamadiski okuqala ngo-20%.
