Iiphedi ze-Ceramic brake zibhukuqa ingqikelelo yesiqhelo yee-ceramic brake pads, ii-ceramic brake pads zenziwe nge-ceramic fibers, izinto zokuzalisa ezingenazintsimbi, izinto zokuncamathelisa kunye nexabiso elincinci lesinyithi.
Iipedi ze-ceramic brake luhlobo lwe-brake pads, abathengi abaninzi baya kuphosakela nge-ceramic ekuqaleni, enyanisweni, iipads ze-ceramic brake ziphuma kumgaqo we-ceramics we-ceramics kune-non-metallic ceramics, ii-brake pads ngenxa yesantya esiphezulu, ubushushu obuphezulu. kumphezulu wokukhuhlana, ngokomlinganiselo, unokufikelela kwi-800 ~ 900 degrees, kwaye enye nangaphezulu. Kulo bushushu obuphezulu, umphezulu we-brake pad uya kuba nempendulo efanayo ye-cermet sintering, ukwenzela ukuba i-brake pad ibe nokuzinza okulungileyo kule bushushu. Iipads zesiqhelo aziyi kuvelisa ukusabela kwe-sintering kobu bushushu, ngenxa yokunyuka okubukhali kobushushu bomphezulu kuya kunyibilika izinto ezingaphezulu kunye nokuvelisa umqamelo womoya, nto leyo eya kubangela ukuncipha okubukhali ekusebenzeni kwebhuleki okanye ilahleko yebhuleki emva kokunyathela ngokuqhubekayo.
Iimpawu ze-Ceramic brake pad:
Uthuli oluncinci kumavili; Ubomi obude beepleyiti kunye neeperi; Akukho ngxolo/akukho kungcangcazela/akukho monakalo wediski. Ukusebenza okuthe ngqo kolu hlobo lulandelayo:
(1) Owona mahluko mkhulu phakathi kwee-ceramic brake pads kunye ne-traditional brake pads kukuba akukho ntsimbi. Isinyithi kwimibhobho yesiqhelo iyona nto iphambili yokukhuhlana, i-braking force inkulu, kodwa ukunxiba kukhulu, kwaye ingxolo ilula ukubonakala. Emva kokufakwa kwee-ceramic brake pads, ekuqhubeni ngokuqhelekileyo, akuyi kuba nomsindo ongaqhelekanga (oko kukuthi, ukukrazula isandi). Ngenxa yokuba i-ceramic brake pads ayinayo izakhi zetsimbi, ingxolo yentsimbi yokungqubuzana phakathi kweentsimbi eziqhelekileyo zentsimbi kunye neengxenye ezimbini (oko kukuthi, i-brake pads kunye ne-disc ye-brake) iyagwenywa.
(2) I-coefficient ye-friction ezinzileyo. I-friction coefficient yeyona nto ibalulekileyo yesalathiso sokusebenza kwayo nayiphi na imathiriyeli yokukhuhlana, enxulumene nesakhono sokuqhobosha se-brake pads. Kwinkqubo ye-braking ngenxa yobushushu obuveliswayo, ukunyuka kobushushu bokusebenza, i-brake general pad friction material ichaphazeleka bubushushu, i-coefficient ye-friction iqala ukuhla. Kwizicelo eziphathekayo, ukukhuhlana kuya kuncitshiswa, ngaloo ndlela kuncitshiswe umphumo wokuqhawula. Izinto zokukhuhlana kweepads zebrake eziqhelekileyo azikavuthwa, kwaye i-friction coefficient iphezulu kakhulu, ikhokelela kwizinto ezingakhuselekanga ezifana nelahleko yendlela, ukutshisa, kunye nokukrwela iidiski ze-brake ngexesha loqhoqhoqho. Nangona iqondo lokushisa le-disc ye-brake lifikelela kuma-degrees angama-650, i-coefficient ye-friction ye-ceramic brake pad isekho malunga ne-0.45-0.55, enokuqinisekisa ukuba isithuthi sinokusebenza kakuhle kwe-braking.
(3) I-Ceramics inozinzo oluhle lwe-thermal kunye ne-conductivity ephantsi ye-thermal, ukumelana nokunxiba kakuhle. Ukushisa kwexesha elide lokusetyenziswa yi-1000 degrees, eyenza i-ceramic ifaneleke kwiimfuno eziphezulu zokusebenza kwezixhobo ezahlukeneyo ze-brake yokusebenza, kwaye inokuhlangabezana neemfuno zobugcisa besantya esiphezulu, ukhuseleko kunye nokumelana nokunxiba okuphezulu kweepakethi zokuqhawula.
(4) Inamandla omatshini kunye neempawu zomzimba ezilungileyo. Ukwazi ukumelana noxinzelelo olukhulu kunye namandla okucheba. Iimveliso zezinto zefriction kwindibano ngaphambi kokusetyenziswa, kukho imfuneko yokugaya, indibano kunye nolunye uhlengahlengiso lomatshini, ukwenzela ukuba kwenziwe indibano yebrake pad. Ngoko ke, kuyimfuneko ukuba izinto ezixutywayo kufuneka zibe namandla aneleyo omatshini ukuze kuqinisekiswe ukuba akukho monakalo kunye nokuhlukana ngexesha lokucubungula okanye ukusetyenziswa.
(5) Inokunciphisa kakhulu i-thermal. Ingaba sisizukulwana sokuqala seemveliso ze-ceramic ze-M09 okanye isizukulwana sesine se-ceramic brake pads ye-TD58, isenokuqinisekisa ukuba isithuthi sinokusebenza kakuhle kwe-braking ukuqinisekisa ukhuseleko, kwaye i-phenomenon ye-thermal attenuation ye-brake pads incinci kakhulu. .
(6) Ukuphucula ukusebenza kweebrake pads. Ngenxa yokutshatyalaliswa kobushushu obukhawulezayo bezinto ze-ceramic, i-coefficient yayo ye-friction iphezulu kuneyentsimbi ye-brake pads ekwenzeni iibhuleki.
(7) Ukhuseleko. Iibhreke pads ziya kuvelisa ubushushu obuphezulu ngoko nangoko xa uqhobosha, ingakumbi ngesantya esiphezulu okanye xa uqhobosheka olungxamisekileyo. Kwiqondo lokushisa eliphezulu, i-coefficient ye-friction ye-friction sheet iya kuncipha, ebizwa ngokuba yi-thermal decay. Ukubola okuphantsi kwe-thermal ye-brake pads eziqhelekileyo, iqondo lobushushu eliphezulu kunye nokunyuka kwe-oyile ye-oyile ngexesha likaxakeka kwenza ukulibaziseka kwe-brake, kunye nokulahlekelwa kwempembelelo ye-braking ephantsi.
(8) Ukuthuthuzelwa. Kwiimpawu zokuthuthuzela, abanini bahlala bexhalabele kakhulu ngengxolo ye-brake pads, eneneni, ingxolo nayo yingxaki apho iipads eziqhelekileyo ze-brake azikwazanga ukuyicombulula ixesha elide. Ingxolo iveliswa yintlupheko engaqhelekanga phakathi kwepleyiti ye-friction kunye ne-friction disc, kwaye izizathu zokuveliswa kwayo ziyinkimbinkimbi kakhulu, i-braking force, ukushisa kwe-brake disc, isantya semoto kunye neemeko zemozulu zinokuba yimbangela yengxolo.
Ukongeza, izizathu zengxolo kwizigaba ezintathu ezahlukeneyo zokuqaliswa kwe-braking, ukuphunyezwa kwe-braking kunye nokukhululwa kwe-braking ziyahluka. Ukuba i-frequency yengxolo iphakathi kwe-0 kunye ne-550Hz, imoto ayiyi kuvakala, kodwa ukuba ingaphezulu kwe-800Hz, umnini unokuva ngokucacileyo ingxolo ye-brake.
(9) Iimpawu zezinto eziphathekayo ezigqwesileyo. Iziqhoboshi zeCeramic pads zisebenzisa amasuntswana amakhulu egraphite / ubhedu / iikeramics eziphambili (ezingeyi-asbestos) kunye nesemi-metal kunye nezinye izinto ezikumgangatho ophezulu ezinokumelana nobushushu obuphezulu, ukumelana nokunxiba, ukuzinza kwebrake, ukulungisa umonakalo webrake disc, ukukhuselwa kwendalo, akukho ngxolo ende. ubomi benkonzo kunye nezinye iingenelo, ukoyisa iiphedi zebrake zemveli kwizinto eziphathekayo kunye neziphene zenkqubo okwangoku zezona ziphucukileyo zehlabathi ze-ceramic brake pads. Ukongeza, umxholo webhola le-ceramic slag uphantsi, uphuculo lulungile, kwaye ukunxitywa kabini kunye nengxolo yeebhuleki ze-brake zingancitshiswa.
(10) Ubomi benkonzo ende. Ubomi benkonzo buyisalathisi esisixhalabele kakhulu, ubomi benkonzo yee-brake pads eziqhelekileyo bungaphantsi kweekhilomitha ezingama-60,000, kwaye ubomi benkonzo ye-ceramic brake pads bungaphezulu kweekhilomitha ezili-100,000. Kungenxa yokuba izinto ezisetyenzisiweyo kwi-ceramic brake pads ziluhlobo olu-1 ukuya kwezi-2 kuphela zomgubo we-electrostatic, kwaye ezinye izinto aziyiyo i-electrostatic materials, ukwenzela ukuba umgubo uya kuthatyathwa ngumoya kunye nokuhamba kwesithuthi, kwaye ayiyi kubambelela kwivili ichaphazela ubuhle bevili. Ubomi bezinto ze-ceramic bungaphezulu kwe-50% ephezulu kunobo be-semi-metal eqhelekileyo. Emva kokusetyenziswa kwe-ceramic brake pads, akuyi kubakho ukukrazula (oko kukuthi, ukukrazula) kwi-disc ye-brake, eyandisa ubomi benkonzo ye-original car brake disc ngama-20%.
