Ceramic brake pads inopidigura pfungwa yechinyakare yeceramic brake pads, ceramic brake pads inoumbwa neceramic fibers, iron-isina filler zvinhu, adhesive uye shoma shoma simbi.
Ceramic brake pads imhando yemabrake pads, vatengi vazhinji vachange vakanganisa neceramic pakutanga, kutaura zvazviri, ceramic brake pads anobva pamusimboti wesimbi ceramics pane asiri-metallic ceramics, brake pads nekuda kwekumhanyisa braking, kupisa kwakanyanya. pane friction surface, maererano nechiyero, inogona kusvika 800 ~ 900 degrees, uye mamwe akatokwira. Pane iyi tembiricha yepamusoro, pamusoro pebhureki pad ichava nekuita kwakafanana kwecermet sintering, kuitira kuti brake pad ine kugadzikana kwakanaka pakupisa uku. Iwo echinyakare mabhureki mapedhi haaburitse sintering reaction pane ino tembiricha, nekuda kwekukwira kwakanyanya kwekushisa kwepamusoro kunonyungudutsa zvinhu zvepasi uye kuburitsa mhepo cushion, izvo zvinokonzeresa kudzikiswa kwakanyanya kwekuita mabhureki kana kurasikirwa kwemabhureki mushure mekuramba kubhureki.
Ceramic brake pad zvinhu:
Guruva shoma pamavhiri; Hupenyu hurefu hwendiro uye mapeya; Hapana ruzha / hapana kudedera / hapana kukuvara kwe disc. Iyo chaiyo performance ndeyekutevera:
(1) Musiyano mukuru pakati peceramic brake pads uye yechinyakare brake pads ndeyekuti hapana simbi. Simbi mumapedhi echinyakare mabhureki ndiyo inonyanya kukwesha zvinhu, simba rekubhureki rakakura, asi kupfeka kwakakura, uye ruzha rwuri nyore kuoneka. Mushure mekuiswa kweceramic brake pads, mukutyaira kwakajairwa, hapazovi neruzha rusina kujairika (kureva, kukwenya ruzha). Nekuti mapedhi eceramic mabhureki haana simbi, ruzha rwesimbi rwekukweshana pakati pechinyakare simbi mabhureki pads uye maviri mativi (kureva, mabhureki pads uye bhureki disc) inodziviswa.
(2) Yakagadzikana friction coefficient. Friction coefficient ndiyo inonyanya kukosha performance index yechero friction material, ine chekuita nekukwanisa kubhureki kwemabrake pads. Mukuita mabhureki nekuda kwekukwesha kwakagadzirwa kupisa, kuwedzera kwekushisa kwekushanda, iyo general brake pad friction material inokanganiswa nekupisa, friction coefficient inotanga kudzikira. Mumashandisirwo anoshanda, friction inodzikiswa, nekudaro ichidzikisa mabhureki maitiro. Iko friction yezvakajairwa mabhureki pads haina kukura, uye friction coefficient yakakwira zvakanyanya, zvichikonzera zvinhu zvisina kuchengetedzeka sekurasikirwa negwara, kupisa, uye kukwenya kwemabhureki disc panguva yekubhureki. Kunyangwe kana tembiricha yebhureki disc inosvika 650 madhigirii, iyo friction coefficient yeceramic brake pad ichiri ye 0.45-0.55, iyo inogona kuve nechokwadi chekuti mota ine yakanaka braking performance.
(3) Ceramics ine yakanaka yekudziya kugadzikana uye yakaderera yekupisa conductivity, yakanaka kupfeka kuramba. Iyo tembiricha yenguva refu yekushandisa ndeye 1000 madhigirii, inoita kuti ceramic ikwane kune yakakwira kuita zvinodiwa zveakasiyana siyana ekuita mabhureki zvinhu, uye inogona kusangana nehunyanzvi zvinodiwa zvekumhanya zvakanyanya, chengetedzo uye yakakwirira kupfeka kuramba kwemabrake pads.
(4) Iine simba rakanaka remagetsi uye zvinhu zvemuviri. Kugona kumirisana nekumanikidza kukuru uye simba rekugera. Friction zvinhu zvigadzirwa mumusangano usati washandiswa, pane kudikanwa kwekuboora, kusangana uye kumwe kugadziridzwa kwemuchina, kuitira kugadzira mabhureki pad musangano. Naizvozvo, zvinodikanwa kuti iyo friction zvinhu zvinofanirwa kuve neyakakwana mechani simba kuti ive nechokwadi chekuti hapana kukuvadzwa uye kupatsanurwa panguva yekugadzirisa kana kushandiswa.
(5) Iine kuderera kwakanyanya kwekushisa. Ingave iri chizvarwa chekutanga chezvigadzirwa zveceramic zveM09 kana chizvarwa chechina checeramic brake pads yeTD58, inogona kuramba ichive nechokwadi chekuti mota ine mabhureki akanaka kuti ive nechokwadi chekuchengetedza, uye chiitiko chekudziya kwekupisa kwemabhureki pads idiki kwazvo. .
(6) Kuvandudza mashandiro emabhureki pads. Nekuda kwekukurumidza kupisa kwekupisa kwezvinhu zveceramic, friction coefficient yayo yakakwirira kupfuura yesimbi brake pads mukugadzira mabhureki.
(7) Chengetedzo. Mabhureki mabhureki anoburitsa tembiricha yakakwira nekukasika kana uchibharaki, kunyanya pakumhanya zvakanyanya kana emergency braking. Pakupisa kwakanyanya, friction coefficient ye friction sheet ichaderera, iyo inonzi thermal decay. Iko kuderera kwemafuta ekuora kweakajairwa mabhureki pads, tembiricha yepamusoro uye tembiricha yemafuta ebhureki inokwira panguva yekukurumidzira mabhureki inoita kuti brake inonoke, uye kunyangwe kurasikirwa kwebhureki mhedzisiro yakaderera kuchengetedza chinhu.
(8) Nyaradzo. Mune zviratidzo zvekunyaradza, varidzi vanowanzonyanya kunetseka nezveruzha rwemabhureki pads, kutaura zvazviri, ruzha idambudziko iro rakajairwa mabhureki padhi rakatadza kugadzirisa kwenguva yakareba. Ruzha runogadzirwa nekukakavadzana kusingaite pakati peiyo friction plate uye friction disc, uye zvikonzero zvekugadzirwa kwayo zvakanyanya kuoma, braking force, brake disc tembiricha, kumhanya kwemotokari uye mamiriro ekunze anogona kunge ari chikonzero cheruzha.
Pamusoro pezvo, zvikonzero zveruzha mumatanho matatu akasiyana ekutanga mabhureki, kuita mabhureki uye kuburitswa kwebhureki zvakasiyana. Kana ruzha rweruzha rwuri pakati pe0 ne550Hz, mota haizonzwiki, asi kana inopfuura 800Hz, muridzi anogona kunzwa ruzha rwebhureki zviri pachena.
(9) Hunhu hwakanaka hwezvinhu. Ceramic brake pads uchishandisa zvimedu zvihombe zvegraphite/bras/advanced ceramics (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 echinyakare mabhureki pads pane zvinhu uye maitiro akaremara pari zvino ndiyo yakanyanya kuomesesa epamusoro ceramic brake pads. Uye zvakare, iyo ceramic slag bhora yemukati yakaderera, iyo inosimudzira yakanaka, uye maviri maviri kupfeka uye ruzha rwemabhureki pads anogona kuderedzwa.
(10) Hupenyu hurefu hwebasa. Hupenyu hwesevhisi chiratidzo chatiri kunetsekana nacho, hupenyu hwesevhisi hweakajairwa mabhureki padhi huri pasi pemakiromita makumi matanhatu, uye hupenyu hwesevhisi yeceramic brake pads inodarika 100,000 makiromita. Izvi zvinodaro nekuti iyo yakasarudzika formula material inoshandiswa muceramic brake pads ingori 1 kusvika ku2 mhando dze electrostatic poda, uye zvimwe zvinhu hazvisi-electrostatic materials, zvekuti hupfu huchatorwa nemhepo nekufamba kwemota, uye hazvizoomerera kune vhiri zvinokanganisa kunaka kwevhiri. Hupenyu hwezvinhu zveceramic hunodarika 50% yakakwirira kupfuura iyo yakajairwa semi-simbi. Mushure mekushandiswa kweceramic brake pads, hapazove nekukwenya (kureva kuti, kukwenya) pane bhureki disc, iyo inowedzera hupenyu hwebasa reiyo yekutanga mota brake disc ne20%.
