Nhoroondo yekushanduka kwemota brake friction materials

Kuvandudzwa kwemotokari mabhureki friction zvinhu zvakakamurwa kuita matanho matatu anotevera: nhanho yekutanga idanho rekugadzirwa kwezvinhu zvemabhureki, ayo anonyanya kuve mabhureki engoma;danho rechipiri ndiyo nhanho yekukurumidza kukura kwezvinhu zvebhureki , Zvizhinji zvezvinhu zvitsva zvakatanga kuberekwa.Danho iri ndiro bhureki rinonyanya kushandisa mabhureki edhisiki;danho rechitatu ndiyo nhanho apo bhureki zvinhu zvinokura kusvika panhongonya, uye danho iri bhureki rinonyanya kushandisa dhisiki mabhureki, zvakasiyana-siyana itsva zvinhu zviri kubuda murukova kusingaperi.

Tekinoroji mwero uye kuumbwa kwemota brake friction material

1.1 Technical Standards

Kutanga, yakakodzera uye yakatsetseka anti-friction properties.Yakakodzera uye yakagadzikana anti-friction zvivakwa zvinogona kuvimbisa "nyoro" kukwesha.Chechipiri, yakanakisa mechanical simba uye muviri zvinhu.Simba reMechanical rinogona kuve nechokwadi chekuti zvinhu zvacho hazvitani kuputsika uye kudzivirira mhedzisiro yakakomba inogona kukonzerwa nekutadza kwebhureki.Chechitatu, kuderera kwebhureki ruzha.Kuti uchengetedze nharaunda, ruzha rwemota braking harufanire kudarika 85dB.Chechina, kuderedza kupfeka pane chassis.Iyo braking process inofanirwa kudzivirira kupera uye kukwenya pane friction disc.

1.2 Kuumbwa kwezvinhu zvebrake friction

Kutanga, organic binders.Phenolic resins uye modified phenolic resins mhando mbiri dzakanyanya kukosha.Chechipiri, fiber yakasimbiswa zvinhu.Metal fibers inotsiva asbestos sechinhu chikuru, uye zvinhu zvekuzora, mafirita uye friction modifiers akaiswa musimbi uye akasiiwa kugadzira sintered brake friction materials.Chechitatu, filler.Iwo ane hukama reagents akagadzirwa uye mareagents anodzora friction zvivakwa zvinoumba chikamu ichi.

1.3 Kurongwa kweMotokari Brake Materials

(1) Asbestos brake friction material: yakanaka yakazara friction performance, high melting point, high mechanical simba uye yakasimba adsorption simba inoita kuti asbestos fibers ibude pachena.Kubva 1970, kusimukira kwayo kwave kudziviswa nekusaita kupisa kwekutamisa kuita uye kuwedzera kupfeka kwezvinhu.
(2) Metal-based non-asbestos brake friction material: Iyo brake friction material yakagadzirwa nemoto-calcined simbi uye yakanyatsokamurwa simbi inoumbwa nechinhu ichi.Iyo calcined iron nemhangura nedzimwe simbi dzakaoma kupatsanura uye nyore kusanganisa.kusashandisa.Mukupesana, iyo yakakamurwa zvakatsetseka simbi brake friction material inoumbwa nemhangura nesimbi haishandiswe zvakanyanya nekuda kwekudhura kwayo, matanho ekugadzira akawandisa, uye nyore kugadzirwa kweruzha.
(3) Semi-metal-based non-asbestos brake friction material: dzakasiyana-siyana dzisiri dzesimbi fiber uye simbi fibers dzinovandudza zvikuru kupesana kwekuputika kwezvinhu zvebhureki, saka zvinoshandiswa zvakanyanya.Nekudaro, simbi dzayo dzesimbi dziri nyore kuita ngura uye dzinotungamira mukupfeka kwakakomba uye mamwe matambudziko achiri kutarisisa kwetsvakiridzo nenyanzvi kubva kumativi ese ehupenyu.
(4) Non-metallic-based non-asbestos brake friction materials: zvakasiyana-siyana kabhoni/carbon friction zvinhu zvinokunda nekugona kwazvo kukweshana uye kukwirira kubhenda kuramba.Asi mutengo wepamusoro unoganhurirawo kusimudzirwa kwayo.Pasi rose, nyika yangu iri pachinzvimbo chekutungamira mukugadzirira kwakasiyana kabhoni / kabhoni brake zvinhu.
(5) Yakasiyana-siyana mabhureki friction zvinhu mumunda weinjiniya ceramics: hunhu hwekupfeka kwakaderera, huwandu hwekupisa uye anti-friction zvakaita kuti vaongorori vazhinji vashandise iyi inorganic isiri-simbi zvinhu kugadzira mabhureki zvinhu, uye kufambira mberi kwaitwa. .Nekudaro, iyo yakashata yekuputswa nyore nyore zvakare inodzikamisa nzvimbo yayo yekushandisa.

Kuvandudza maitiro edzimba dzemotokari brake zvinhu

Parizvino, iyo dhizaini yekuumbwa ichiri nzvimbo yekutanga yekutsvagisa yemotokari brake friction materials.Kunyange zvazvo nzira dzacho dzichisiyana munyika nenyika, kuvandudza kushanda kwezvinhu zvitsva zvinokweshana uye kusangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza zvichiri chinangwa chekupedzisira.Pasi pehutungamiriri hwedzidziso yekusimudzira, kusimudzira kutariswa kwezvinhu zvebrake friction kwave kusimukira kune maitiro eruzha rwakaderera uye pasina kusvibiswa.Kusimukira uku kunopindiranawo nemaitiro azvino uye zvinodiwa nemagariro.Nekukurumidza kusimudzira kwehunyanzvi hwekugadzira, Iko kuvandudza kwemotokari mabhureki zvinhu kucharatidzawo akasiyana maitiro.Diversified brake zvinhu zvinogona kusarudzirwa mota dzine mamiriro ekunze akasiyana, matunhu uye mabasa.Nenzira iyi, iyo braking performance yemotokari inogona kutamba yakakwirira-yekuita uye yakakwirira-inoshanda braking maitiro.

Mumamiriro ezvinhu akajairwa, kufambira mberi kwesainzi uye tekinoroji ndiyo vimbiso yekugadzirisa uye kusiyanisa kwezvinhu zvebrake friction, uye zvakare inogona kusangana nezvinodiwa zveindasitiri yemotokari.Izvo zvinokanganisa zvefiber imwe yakasimbiswa hazvidziviriki, iyo yakatsetseka pamusoro pegirazi fiber inonetsa kupinda neresin;simbi zvinhu zvakaoma kudzivisa dambudziko ngura;carbon material yakaoma mukuita, yakakwirira mumutengo, uye yakaoma kusimudzira.Naizvozvo, mahybrid fibers ave kutarisisa kwekutsvaga kwenyika dzakasiyana.Simbi fibers, kabhoni faibha, kabhoni faibha uye mhangura faibha zvinogona kukwevera pane akasiyana mabhenefiti, kupa kutamba kwakazara kune zvakanakira faibha, kuderedza mitengo, nekuvandudza mashandiro.Kugadzirisa dambudziko re phenolic resin pasi pekuita kwekushisa kwakanyanya, mabhizinesi mazhinji uye masangano ekutsvagisa kwesainzi anoshandisa zvimwe zvakanakisa zvigadzirwa zvakaita sebutylbenzene kugadzira phenolic resin yakasiyana neyekare kuburikidza nekutsvaga kwavo nekusimudzira.Naizvozvo, yakadai yakagadziridzwa phenolic resin Resin zvakare igwara idzva rekutsvagisa nekuvandudza kwemotokari mabhureki friction zvinhu.

Pfupisa

Kupfupisa, kuvandudzwa kwemotokari mabhureki friction zvinhu zvinobuda imwe mushure meimwe mukugadzirwa kwemotokari, iyo yakaita basa rekutyaira mukuvandudza mashandiro emota braking.Nekuvandudzwa kwetekinoroji nyowani uye zvinhu zvitsva, maitiro ekusimudzira emotokari mabhureki friction zvinhu acharatidza kusiyanisa uye kuderera kwekushandisa, uye kuvandudzwa kwehunyanzvi hwezvinhu kuchasimudzirawo kuvandudzwa kwemotokari mabhureki friction zvinhu.
