Ceramic brake pads imhando yemabhureki padhi inosanganisira mineral fiber, aramid faibha uye ceramic faibha (nekuti simbi faibha inogona kuita ngura, inoburitsa ruzha uye guruva, uye saka haigone kusangana nezvinodiwa zvedomi mhando maumbirwo).
Vatengi vazhinji vanozotanga kukanganisa ceramic seyakagadzirwa neceramic, asi kutaura zvazviri, ceramic brake pads inogadzirwa kubva pamusimboti wesimbi ceramics pane isiri-simbi ceramics.Pane iyi tembiricha yepamusoro, pamusoro pebhureki padhi ichave yakanyungudutswa simbi-ceramic yakafanana maitiro, kuitira kuti brake pad ine kugadzikana kwakanaka pakupisa uku.Traditional brake pads haaburitse sintering reaction pane iyi tembiricha, uye kuwedzera kwakanyanya kwekushisa kwepamusoro kunogona kukonzera kuti zvinhu zvepasi zvinyunguduke kana kuburitsa cushion yemhepo, izvo zvinogona kukonzera kudzikira kwakanyanya kwekuita mabhureki mushure mekuramba kubhureki kana kurasikirwa zvachose. ye braking.
Ceramic brake pads ine zvinotevera zvakanakira pane mamwe marudzi emabhureki pads.
(1) Musiyano mukuru pakati peceramic brake pads uye zvechinyakare brake pads kusavapo kwesimbi.Mune zvechinyakare mabhureki mapedhi, simbi ndicho chinhu chikuru chinoburitsa friction, iyo ine high braking force, asi inogara ichipfeka uye ruzha.Kana mabhureki eceramic akaiswa, hapazove nekukakavadzana (kureva kukwesha ruzha) panguva yekutyaira.Nekuda kwekuti mabrake pads eceramic haana zvinhu zvesimbi, ruzha rwemabhureke echinyakare rwesimbi runokweshana (kureva mabhureki nemabhureki disc) runodziviswa.
(2) Yakagadzikana friction coefficient.Friction coefficient ndiyo inonyanya kukosha yekuita chiratidzo chechero friction zvinhu, zvine hukama neiyo yakanaka kana yakaipa braking kugona kwebrake pads.Mukuita mabhureki nekuda kwekupisa kunoitwa nekukwesha, tembiricha yekushanda inowedzera, iyo general friction material yebrake pad nekupisa, coefficient of friction inotanga kuderera.Mukushandisa chaiko, inoderedza simba rekukwenya, nekudaro ichidzikisa mabhureki maitiro.Iyo yekukwesha zvinhu zveakajairwa mabhureki pads haina kukura, uye friction coefficient yakanyanyisa kukonzeresa zvinhu zvisina kuchengetedzeka sekurasikirwa kwenzira panguva yekubhureki, kutsva mapadhi uye kukwenya mabhureki disc.Kunyangwe tembiricha yebhureki disc yakakwira kusvika 650 madhigirii, iyo friction coefficient yeceramic brake pads ichiri kutenderera 0.45-0.55, iyo inogona kuve nechokwadi chekuti mota ine yakanaka braking performance.
(3) Ceramic ine zviri nani kupisa kugadzikana uye yakadzika yekupisa conductivity, uye yakanaka kupfeka kuramba.Tembiricha yenguva refu yekushandiswa mu1000 madhigirii, hunhu uhu hunoita kuti ceramic huve hwakakodzera kune dzakasiyana-siyana dzepamusoro-inoshanda mabhureki zvinhu, yakakwirira-inoshanda zvinodiwa, inogona kusangana nebhureki padhi yepamusoro-kumhanya, chengetedzo, yakakwirira kupfeka kuramba uye zvimwe zvinodiwa zvehunyanzvi.
(4) Iine simba rakanaka remagetsi uye zvinhu zvemuviri.Inogona kumira kumanikidzwa kukuru uye simba rekugera.Friction zvinhu zvigadzirwa mumusangano usati washandiswa, pane kudiwa kwekuchera, kusangana uye kumwe kugadzirisa kwemakanika, kuitira kugadzira iyo brake pad assembly.Naizvozvo, iyo friction zvinhu zvinofanirwa kunge zvine simba rakakwana remuchina kuti ive nechokwadi chekuti kugadzirisa kana kushandiswa kwemaitiro hakuratidzike kutyora nekupwanya.
(5) Iva nechinhu chakaderera chekuora kwemafuta.
(6) Wedzera mashandiro emabhureki pads.Nekuda kwekukurumidza kupisa kwekupisa kwezvinhu zveceramic, inoshandiswa mukugadzira mabhureki, uye iyo coefficient ye friction yakakwirira kupfuura yesimbi brake pads.
(7) Kuchengeteka.Mabhureki mabhureki anogadzira tembiricha yakakwira nekukasika kana uchibhureki, kunyanya pakumhanya zvakanyanya kana emergency braking.Mumamiriro ekupisa kwepamusoro, friction coefficient ye friction pads inodonha, inonzi thermal recession.Zvakajairwa mabhureki pads kupisa kwekudzikira kwepasi, tembiricha yakakwira uye yekukurumidzira braking kana tembiricha yebhureki yakawedzera kuitira kuti kunonoka kwebhureki, kana kunyange kurasikirwa kwebhureki mhedzisiro yekuchengetedza chinhu kwakadzikira.
(8) kunyaradza.Pakati pezviratidziro zvekunyaradza, varidzi vanowanzo nyanya kunetseka nezve ruzha rwemabhureki pads, kutaura zvazviri, ruzha idambudziko rakareba risingagone kugadziriswa neakajairwa mabhureki pads.Ruzha rwunogadzirwa nekukweshana kusingaite pakati pefiction pad uye friction disc, uye zvikonzero zvechizvarwa chayo zvakanyanya kuomarara, senge braking force, tembiricha yebrake disc, kumhanya kwemotokari uye mamiriro ekunze. zvese zvinobvira zvikonzero zveruzha.
(9) Hunhu hwakanaka hwezvinhu.Ceramic brake pads inoshandisa zvimedu zvakakura zve graphite/bras/advanced ceramic (isina-asbestos) uye semi-metal nezvimwe zvinhu zvepamusoro-tekinoroji zvine tembiricha inodzivirira, kusapfeka, kugadzikana kwemabhureki, kugadzirisa kukuvara kwebhureki disc, kuchengetedza kwezvakatipoteredza, pasina ruzha rurefu. hupenyu hwesevhisi uye zvimwe zvakanakira, kukurira yechinyakare brake pad zvinhu uye maitiro akaremara ndiyo yakanyanya kuomesesa yepasirese yepamusoro ceramic brake pads.Uye zvakare, iyo yakaderera yemukati yeceramic slag bhora uye yakanaka yekusimudzira inogona zvakare kudzikisa maviri kupfeka uye ruzha rwemabhureki pads.
(10) Hupenyu hurefu hwebasa.Upenyu hwebasa chiratidzo chekunetseka kukuru.Hupenyu hwesevhisi hweakajairwa mabhureki pads huri pazasi 60,000 km, nepo hupenyu hwesevhisi hweceramic brake pads huri pamusoro pe100,000 km.Izvi zvinodaro nekuti ceramic brake pads inoshandisa yakasarudzika formula ye1 kusvika ku2 mhando dze electrostatic poda, zvimwe zvinhu hazvisi-static zvinhu, zvekuti hupfu huchatorwa nemhepo nekufamba kwemota, uye haibatike. kune vhiri hub kukanganisa runako.Hupenyu hurefu hwezvinhu zveceramic hunodarika 50% yakakwirira kupfuura iyo yakajairwa semi-simbi.Mushure mekushandisa ceramic brake pads, hapazove nekukwenya grooves (kureva zvikweshwa) pamabhureki disc, zvichiwedzera hupenyu hwesevhisi hwemadhisiki ekutanga ne20%.
