Nhanganyaya: Parizvino, muindasitiri yemotokari mumamiriro ekugadzirisa magetsi, hungwaru uye kugadzirwa kwemotokari, mabhureki system kuita zvinodiwa zviri kuwedzera zvishoma nezvishoma, uye kabhoni ceramic brake discs ine zvimwe zvakanakira zviri pachena, chinyorwa ichi chichataura nezve carbon ceramic brake disc. industry.
I. Chiitiko Background
Munguva pfupi yapfuura, Azera yakaburitsa yekutanga hombe yezvigaro zvishanu SUV, iyo ES7, iyo inoshandisa yakasanganiswa yakakandwa ese-aluminium kumashure furemu, kechipiri Azera anoshandisa yakabatanidzwa die-casting tekinoroji muzvigadzirwa zvayo.Nekuvandudzwa kwehuremu uye magetsi, iyo yakasanganiswa die-casting tekinoroji iri kutsvakwa nevagadziri vemota nyowani uye makambani emotokari echinyakare, uye kureruka kwechimiro chemotokari pasina mubvunzo chave chikamu chakakosha chemazuva ano dhizaini dhizaini.Iko kushandiswa kwekabhoni ceramic brake discs kuchasimudzira zvine simba maitiro emotokari lightweighting, zvinotevera kutaura nezve indasitiri iyi.
Vaviri, kunzwisisa kabhoni ceramic brake discs
Parizvino, mabhureki emidziyo anoshandiswa zvakanyanya muzvitima zvinomhanya, mota nendege zvinonyanya kuve nehupfu simbi uye kabhoni-kabhoni composite zvinhu.Nekudaro, poda metallurgy brake zvinhu zvine zvikanganiso senge tembiricha yakanyanya nyore bonding, friction performance iri nyore kudzikira, tembiricha yesimba inoderera zvakanyanya, kushomeka kwekushisa kwekushisa, hupenyu hupfupi hwebasa, nezvimwewo;nepo kabhoni kabhoni brake zvinhu zvine yakaderera static uye yakanyorova nyika friction coefficient, yakakura vhoriyamu yekuchengetedza kupisa, kureba kwekugadzira kutenderera uye yakakwirira yekugadzira mutengo, iyo inotadzisa kuenderera mberi kwayo uye kushandiswa.
Carbon ceramic brake discs inosanganisa hunhu hwezvose kabhoni fiber uye polycrystalline silicon carbide.Zvichakadaro, uremu huremu, kuomarara kwakanaka, kugadzikana pasi pekumanikidzwa kwakanyanya uye tembiricha yakakwira, kupisa kutyisa kupikisa uye kucheka kweshear hunhu hwekuoma kwakafanana kwete kungowedzera hupenyu hwebasa rebhureki disc, asiwo kudzivirira matambudziko ese anobva pamutoro.
Chechitatu, mamiriro azvino eindasitiri
1. Carbon ceramic brake disc performance iri nani zvakanyanya pane yakajairwa grey cast iron brake disc, asi mutengo ndiko kukanganisa kwayo.
Parizvino, mabhureki edhisiki anoshandiswa zvakanyanya anowanzo simbi simbi, yakaderera-alloy cast iron, yakajairwa simbi yakakandwa, yakakosha alloy cast simbi, yakaderera-alloy simbi yekunyepedzera uye simbi yakakandwa simbi yakakandwa (simbi yakaumbwa) inoumbwa zvinhu, simbi yakakandwa. zvinhu zvinoshandiswa zvakanyanya.Zvigadzirwa zvesimbi zvine kutenderera kwenguva refu kwekugadzira, kushata kwemafuta ekupisa uye nyore kugadzira matsemu ekupisa uye zvimwe zvinoshomeka, saka kabhoni uye kabhoni ceramic composite zvinhu zvekugadzira mabhureki zvinhu.
Nekuda kwemutengo wakakwira wecarbon-carbon composite zvinhu, zvinonyanya kushandiswa mabhureki endege, nekuvandudzwa kwenjanji dzinomhanya kwazvo mumakore achangopfuura, masayendisiti epamba nekunze akatanga kusimudzira kugadzirwa kwenjanji dzinomhanya dzekabhoni ceramic composite friction vice. , carbon ceramic composite materials inotarisa pasi rose pakugadzirwa kwezvinhu zvinokweshana, China yave iri mudanho rekutanga, kabhoni ceramic brake discs mune ramangwana kuderedza mutengo wenzvimbo yakakura, inotarisirwa kuve iyo huru yekusimudzira mabhureki. zvigadzirwa Inotarisirwa kuve iyo huru yekuvandudza nzira yezvigadzirwa zvebrake.
2. Iyo yakananga zvinhu mutengo wekabhoni ceramic brake discs yakaderera, uye kune nzvimbo yakakura yekudzikisa mutengo muhunyanzvi uye chiyero.
Muna 2021, mutengo wetoni imwe chete yezvigadzirwa zvekambani zvinopisa zvakatevedzana i370,000 yuan/tani, zvichidzika ne20% kubva pa460,000 yuan/tani muna 2017, uye mutengo wekugadzira tani imwe chete i11.4 miriyoni yuan muna 2021, pasi ne53.8% kubva 246,800 yuan muna 2017, inova yakakosha kudzikisa mutengo wehunyanzvi.Muna 2021, iyo mbishi mutengo wechiyero ndeye 52%.Nekuwedzera kwechiyero, kusimudzira tekinoroji, otomatiki nhanho yekuvandudza uye kabhoni fiber kuderera kwemutengo, kune nzvimbo hombe yekudzikisa mutengo wechigadzirwa.Ikozvino kabhoni ceramic brake pad imwe chidimbu mutengo ingangoita 2500-3500 yuan, nekuti neC kirasi uye pamusoro pemusika wemotokari dzevatyairi, zvinotarisirwa kuti muna 2025 kukosha kwechidimbu chimwe chete kunotarisirwa kudonha kusvika pa1000-1200 yuan, ichave pasi. kuB kirasi uye pamusoro pemusika wemotokari dzevafambi.
Chechina, tarisiro yeindasitiri
1. Carbon Ceramic brake discs vane nzvimbo yakawanda yekutsiva mudzimba
Nekuda kwekuoma kwemaitiro, kuoma kwekugadzira, kutenderera kwenguva refu kwekugadzira uye zvimwe zvikumbaridzo, mabhizinesi epamba anogona kuburitsa kabhoni ceramic discs mashoma.Vatengesi vakuru ve carbon ceramic composite brake discs vanosanganisira Brembo (Italy), Surface Transforms Plc (UK), Fusionbrakes (USA), nezvimwewo inzvimbo yakakura yekutsiva imba.
Vatengi vakuru vekumhiri kwemakungwa kabhoni ceramic brake disc vagadziri vagadziri vemotokari dzemitambo yepamusoro, uye mutengo weyuniti yezvigadzirwa wakakwira.Tora mhiri kwemakungwa kambani Brembo semuenzaniso, mutengo wechigadzirwa chekabhoni imwe kabhoni ceramic disc inodarika 100,000 RMB, nepo kukosha kwekabhoni kabhoni zvedongo dhisiki kuri kuita 0.8-12,000 RMB, ine mutengo wakanyanya kwazvo.Nekuenderera mberi kwetekinoroji kubudirira kwemabhizinesi epamba munharaunda iyi, uye kuenderera mberi kwekuchinja kwemaitiro e "yakawedzerwa, yakakwira, yakangwara" mota nyowani dzesimba, mwero wekupinda kwekabhoni ceramic discs emotokari nyowani dzemagetsi inotarisirwa kuramba ichiwedzera.
2. Carbon ceramic brake discs inosangana nemaitiro emotokari lightweighting
Uchapupu hwekuedza hunoratidza kuti kuderedzwa kwe10% muhuremu hwemotokari kunogona kuwedzera kushanda kwemafuta ne6% -8%;kune yega yega kuderedzwa kwe100 kg muhuremu hwemotokari, kushandiswa kwemafuta kunogona kudzikiswa ne0.3 - -0.6 litita pa100 km, saka tekinoroji yakareruka ndiyo nzira yakakosha yekuvandudza mota dzemangwana.
Deredza huremu pazasi pekumiswa sisitimu nehafu yekuedza, kabhoni ceramic brake disc ndicho chinhu chakakosha kudzikisa huremu.Yese 1kg kuderedzwa pasi peiyo suspension system yakaenzana ne5kg kuderedzwa pamusoro peiyo suspension system.A peya ye380mm saizi kabhoni ceramic discs ingangoita 20kg yakareruka pane grey cast iron discs, iyo yakaenzana ne100kg uremu kuderedzwa mukumiswa system yemota.Pamusoro pezvo, mota yeToyota yepamusoro-soro yeLexus RCF yave kuburikidza neCFRP zvinhu uye kabhoni ceramic brake discs kuderedza huremu hwe70kg mune zvakawanda zvinhu, iyo 22kg inopihwa nekabhoni ceramic brake discs, saka kabhoni ceramic brake discs ye zvikamu zvakakosha zvekudzikisa uremu hwemotokari.

Kutsiva iyo yepakutanga poda metallurgy brake disc ndiyo isingadzivisike maitiro eindastiri iyi: kutanga, mutengo wecarbon fiber uchaderera zvishoma nezvishoma kutyaira pasi mutengo wakananga wechigadzirwa pachako;chechipiri, nekukwira kwekugadzirwa uye kutengesa chiyero, iyo optimization yegadziriro yekubatanidza, hupfumi hwekuyera huchaunza pasi mutengo we carbon ceramic brake disc;chechitatu, ruzivo rwekutyaira rwakachengeteka runosimudzira kukwidziridzwa kwezvigadzirwa muindasitiri yemotokari.2023 inotarisirwa kuve gore rekutanga rekusimudzira kabhoni ceramic brake disc.Gore rekutanga rekusimudzira mabhureki disc, musika wepamusha unotarisirwa kusvika 7.8 bhiriyoni yuan muna 2025, uye saizi yemusika wepamba inotarisirwa kudarika mabhiriyoni makumi maviri emayuan muna 2030.
Panosvika gore ra2025, kukura kwemusika kwechinyakare simbi mabhureki mabhureki discs anenge 90 bhiriyoni yuan zvichienderana nemutengo we1000 yuan pamotokari imwe chete uye 90 miriyoni mota dzinotengeswa pasi rose, uye musika wepamba uchave pedyo ne30 bhiriyoni yuan.Nekukwidziridzwa kwemagetsi, mwero wekupinda kwekabhoni ceramic brake discs ungangopfuura zvatinotarisira.Uyu musika mutsva unoenderana neyakajairwa maitiro emagetsi ehungwaru kuvandudza uye kubudirira kwe0-1.Uye nezvekuchengetedzwa kwemotokari kufunga, kana budiriro ichinge yave nzvimbo yekutengesa kuchengetedza kwemotokari, mwero wekusimudzira unotarisirwa kudarika zvinotarisirwa, uye remangwana remari rekutengesa remusika rinotarisirwa kusvika pa200-300 bhiriyoni yuan.
