Brake mapads ndiyo yakanyanya kuchengeteka zvikamu muBrake System, iyo inoita basa rekusarudza mumhando yeiyo brake maitiro, uye iyo yakanaka brake pad ndiyo Dziviriro yevanhu nemotokari (ndege).
Kutanga, iko kwakatangira mapuranga
Muna 1897, Herbertfrood akagadzira mapani ekutanga bhuroka Ipapo muna 1909, kambani yakagadzira yekutanga yenyika yakasimbiswa asbestos-yakavakirwa brake pad; Muna 1968, iyo yekutanga yenyika-yesimbi-simbi mabhureki mapads akagadzirwa, uye kubvira ipapo, zvigadzirwa zvekupokana zvakatanga kuvandudza kune asbestos-yemahara. Kumba uye kunze kwenyika kwakatanga kudzidza akasiyana-siyana eAsbestos kutsiva simbi simbi, girazi fiber, airamid fiber, kabhoni fiber uye zvimwe zvinoshandiswa muzvinyorwa zvekupokana.
Chechipiri, kugadziriswa kweBrake mapadhi
Pane nzira mbiri huru dzekutsikisa mabhureki. Imwe inogovaniswa nekushandiswa kwemasangano. Akaita semotokari brake zvinhu, chitima mabhureki midziyo uye zvekushandisa mabrake mabhureki. Iyo nzira yekufananidza iri nyore uye nyore kunzwisisa. Imwe yakakamurwa zvinoenderana nemhando yezvinhu. Iyi nzira yekufananidza inonyanya kufanana nesainzi. Zvishandiso zvemazuva ano zvinonyanya kusanganisira zvikamu zvitatu zvekutevera
Yetatu, mota inobhururuka
1, mhando yemotokari inokatyamadza zvinhu zvinoenderana nezvinhu zvekugadzira zvakasiyana. Inogona kukamurwa kuita asbestos pepa, semi-simbi sheet kana yakaderera simbi sheet, no (asbestos yemahara organic zvinhu) pepa, carbon carbon bepa uye caramic pepa.
1.1.asbestos pepa
Kubva pakutanga chaiko, asbestos yave ichishandiswa seyakasvibiswa seyakaisimbisa mapads, nekuti asbestos fiber ine simba rakanyanya, saka rinogona kuita zvinodiwa neBrake mapuru uye clutch discs uye magirazi. Iyi fiber ine simba rakasimba, rinogona kutora simbi yegiredhi refu, uye inogona kutsungirira tembiricha ye136 ° C. Chii chakawanda, asbestos iri yakachipa. Iyo inobviswa kubva pamshibole ore, iyo inowanikwa mune yakakura yakawanda munyika dzakawanda. ASBestos Frontification zvinhu zvinonyanya kushandisa ashestos fiber, iyo hydrate magnesium silteum (3mgo · 2sio2 · 2h2o) sekusimbisa fiber. Filer yekugadzirisa mafuro emwenje inowedzerwa. Iyo organic matrix composite inowanikwa nekudzvanya chinonamatira mune inopisa cholk.
Pamberi pa1970s. Asbestos mhando mashitsi ekupokana anoshandiswa zvakanyanya munyika. Uye kutongwa kwenguva yakareba. Nekudaro, nekuda kwekushambadzira kwekushisa kwekushambadzira kweAsbestos. Kupisa kwekupisa hakugone kunyimwa nekukurumidza. Izvo zvichaita kuti awedzerwe kuora kweiyo denderedzwa rekupokana kwekupokana kuti riite. Wedzera kupfeka zvinhu. Panguva iyoyo. Mvura yekristaro yeAsbestos fiber yakagadzirirwa pamusoro 400 ℃. Iyo pfuma yekupokana yakadzikira zvakanyanya uye kupfeka kunoshamisa kana kuchisvika 550 kana kupfuura. Mvura yekristaro yakarasika zvakanyanya. Kuwedzera kwakarasika zvachose. Zvinotonyanya kukosha. Zvinoratidzwa zvakaringana. Asbestos chinhu chine kukuvara kwakanyanya kune nhengo dzinoyevedza vanhu. Chikunguru 1989. Iyo US US Privity Dziviriro Agency (EPA) yakazivisa kuti yaizorambidza mari, yekugadzira, uye kugadzirisa kwezvinhu zvese zveAsbestos pakazosvika 1997.
1.2, semi-simbi sheet
Iyo mhando nyowani yezvinyorwa zvekupokana yakagadzirwa pane hwaro hwekupokana kwekupokana uye tsika yechinyakare powder metallurgy friction zvinyorwa. Inoshandisa mesimbi machira panzvimbo yeAsbestos Fibers. Iyo is is is is is is-asbestos friction yekukakavara yakagadzirwa neAmerican Bendis kambani kutanga kwa1970s.
"Semi-simbi" Hybrid brake mapads (semi-akasangana) anonyanya kugadzirwa neakashata simbi masimbi seinosimbisa fiber uye musanganiswa wakakosha. Asbestos uye isiri-asbestos organic brake mapads (no) inogona kusiyaniswa kubva pakuonekwa (fills fils uye zvimedu), uye ivo zvakare vane zvimwe zvinhu zvemagineti.
Semi-Metallic Friction Friction Eque ine inotevera huru maitiro:
(l) yakagadzikana kwazvo pazasi pehukama hwekupokana. Haaburitidzi kuora kwemvura. Yakanaka yekudzikisira;
(2) Kwakanaka kupfeka kurwisa. Hupenyu hwebasa ndeye 3-5 nguva dzevashandisi veAsbestos Frontion;
.
(4) yakanaka yekufambisa inonhuwirira. Tembiricha tembiricha idiki. Inonyanya kukodzera kune zvidiki disc brake zvigadzirwa;
(5) diki diki braking ruzha.
United States, Europe, Japan nedzimwe nyika vakatanga kusimudzira kushandiswa kwenzvimbo huru muma1960. Kupfeka kupokana kweseti-simbi pepa kunodarika 25% yakakwirira kupfuura iyo yeasbestos pepa. Parizvino, inogara chinzvimbo chakakurumbira mumusika wepamaki muhomwe muChina. Uye mota zhinji dzeAmerica. Kunyanya mota uye vatakuri uye mota dzinotakura mota. Semi-simbi brake lining yakavezwa kune anopfuura makumi masere muzana.
Nekudaro, chigadzirwa icho zvakare chine kutevera kutevera:
.
(2) Kukwikwidza kwakakwirira
.
(4) yakakura kwazvo.
Kunyangwe "simbi-simbi" haina zvidiki zvidiki, asi nekuda kwekutadza kwayo kwekugadzira, mutengo wakaderera, ichiri zvinhu zvinodikanwa zvemotokari dzevatambi.
1.3. Nao firimu
Mukutanga kwa1980, pakanga paine akasiyana-siyana emabria akasimbisa asbestos-yemahara mabhureki munyika, kureva kuti, chizvarwa chechitatu cheAsbestos-isina organic zvinhu Nao Type Brake Mapads. Chinangwa chayo ndechekuti urware hwesimbi simbi yakasimbiswa semi-metallic mabhureki, arers fiber fiber, girazi fiber, ceramic fiber, carbon fiber, minerali fiber, mineral fiber uye zvichingodaro. Nekuda kwekushandiswa kwemarobhoti akawanda, mafambiro ari muBrake lining expiner eyakafanana, uye zviri nyore kugadzira brake lining formula nekuita kwakazara kwakazara. Iko kukwezva kweNao pepa ndeyekuchengetedza zvakanaka braking maitiro kuderera kana kupisa kwakanyanya, kuderedza hupenyu hweBrake disc, zvinomiririra iyo iripo yekuvandudza nzira yezvishandiso zvekupokana. Zvinyorwa zvekupokana zvinoshandiswa nenyika dzese dzakakurumbira dzeBenz / Philodo brake mapads ndeye chechitatu-learos
1.4, kabhoni carbon bepa
Carbon Carbon Composite Chinyorwa Chinyorwa rudzi rwezvinyorwa zveCarbon fiber yakasimbiswa carbon matrix. Zvivakwa zvaro zvinokatyamadza zvakanaka. Low density (simbi chete); Yakakura kugona. Iyo ine yakakura kwazvo kupisa simba pane poda simbi yetsvina uye simbi; Kukwirira kwakanyanya kupisa; Hapana deformation, kuamatira phenomenon. Inoshandisa tembiricha inosvika mazana maviri ℃; Kupokana kwakanaka uye kupfeka kuita. Hupenyu hwebasa rebasa. Iyo yekunyepedzera ceefficient yakagadzikana uye ine mwero panguva yekubvaruka. Carbon-kabhoni carbon mashiti yakatanga kushandiswa mumarindi emauto. Yakazotorwa yakazotorwa neFomula 1 Mota dzemotokari, ndeipi chete application yeCarbon Carbon Zvigadzirwa mumatare emagetsi mabhureki mapepa.
Carbon Carbon carposite zvinyorwa zvekupokana chinhu chinokosha nekugadzikana kwekunyora, pfeka kurwisa, magetsi ekuita, simba rakananga, rakanangana nehunyanzvi uye humwe humwe hunhu. Nekudaro, kabhoni-kabhoni yekukwikwidza zvinyorwa zvekupokana zvine zvikanganiso zvinotevera: Iyo yekukakavara haina kugadzikana. Izvo zvinokanganisirwa kwazvo nekunyorova;
Varombo Oxidation Resistance (Zvakakomba oxidation inoitika pamusoro 50 ° C mumhepo). Zvakakwirira zvinodiwa nenzvimbo (yakaoma, yakachena); Zvinodhura zvakanyanya. Iko kushandiswa kunogumira kuminda yakakosha. Ichi ndechimwe chikonzero chikuru nei kudzikisira kabhoni kabhoni zvinhu zvakaoma kukurudzira zvakanyanya.
1.5, zvimedu zve ceramic
Sechigadzirwa chitsva muzvinyorwa zvekupokana. Ceramic Brake mapads ane zvakanakira hapana ruzha, hapana anodonha Ash, hapana Corosion yeVhiri Hub, hupenyu hwakareba hwebasa, kuchengetedza kwezvakatipoteredza uye zvichingodaro. Ceramic Brake mapads pakutanga akagadzirwa neJapan brake makambani emakambani muma1990. Zvishoma nezvishoma zvinova mudiwa mutsva weiyo brake pard musika.
Mumiriri wezvemumiriri weCeramir Vatsvagiri vanobva kuYunivhesiti yeStuttgart uye neGerisheni Aerospace Research Institute vakadzidza kuC / C-SIC Compositi Oak Ridge National Laboratory Cournanced Composite
2, kabhoni ceramic composite brake pad zvakanakira:
1, kana uchienzaniswa neiyo grey grey cast iron brake mapads, uremu hweCarbon Ceramic Mapads anoderedzwa neanenge 60%, uye iyo isingasviki misa yakaderedzwa neanenge 23 makirogiramu;
2, kupokana kwekunyepedzera kwakakura kune kuwedzera kwakanyanya, kumhanya kwekuita kwekuwedzera kunowedzera uye kufambisa kwekushambadzira kwakaderedzwa;
3, iyo tensile elongation yeCarbon Ceramic zvinhu kubva ku0,1% kusvika 0,3%, iyo iri kukosha kwakanyanya kwe ceramic zvinhu;
4.
5, kuitira kuti udzivise kupisa kwakanyanya, pane kupisa kupisa kwepamhepo pistoni yechipfuva uye chidimbu chebrake;
