Umlando wokuvela kwezinto zokushayisana kwamabhuleki emoto

Ukuthuthukiswa kwezinto zokushayisana kwamabhuleki ezimoto kuhlukaniswe izigaba ezintathu ezilandelayo: isigaba sokuqala yisiteji sokuthuthukiswa kwezinto zamabhuleki, ikakhulukazi amabhuleki ezigubhu;isigaba sesibili yisigaba sokuthuthukiswa okusheshayo kwezinto zokubopha , Izinto eziningi ezintsha zaqala ukuzalwa.Lesi sigaba yibhuleki elisebenzisa kakhulu ama-disc brakes;Isigaba sesithathu yisiteji lapho i-brake material ikhula ifinyelela phezulu, futhi lesi sigaba yibhuleki elisebenzisa kakhulu amabhuleki e-disc, kuvela izinhlobonhlobo zezinto ezintsha ngomfudlana ongapheli.

Izinga lobuchwepheshe nokwakheka kwezinto zokushayisana kwamabhuleki emoto

1.1 Amazinga Obuchwepheshe

Okokuqala, izakhiwo ezifanele futhi ezibushelelezi zokulwa ne-friction.Izakhiwo ezifanelekile nezizinzile zokulwa nokungqubuzana zingaqinisekisa ukungqubuzana “okuthambile”.Okwesibili, amandla amahle kakhulu wemishini kanye nezakhiwo zomzimba.Amandla omshini angaqinisekisa ukuthi okokusebenza akujwayele ukuphuka futhi kugweme imiphumela engathi sína engase ibe umphumela wokwehluleka kwamabhuleki.Okwesithathu, umsindo ophansi wamabhuleki.Ukuze kuvikelwe imvelo, umsindo wokubhuleka imoto akufanele udlule ku-85dB.Okwesine, nciphisa ukuguga ku-chassis.Inqubo yokubhuleka kufanele igweme ukuguga kanye nokuklwebheka kudiski yokushayisana.

1.2 Ukwakheka kwezinto zokushayisana kwamabhuleki

Okokuqala, ama-organic binders.Ama-phenolic resins nama-phenolic resins ashintshiwe yizinhlobo ezimbili ezibaluleke kakhulu.Okwesibili, i-fiber reinforced materials.Imicu yensimbi ithatha indawo ye-asbestos njengento eyinhloko, futhi izingxenye zokugcoba, izigcwalisi nezilungisi zokushayisana kushunyekwa ensimbi futhi kufakwe i-sintered ukuze kwakheke izinto zokushayisana kwamabhuleki.Okwesithathu, i-filler.Ama-reagents ahlobene akhiwe kanye nama-reagents alawula izakhiwo zokungqubuzana enza le ngxenye.

1.3 Ukuhlelwa Kwezinto Ezisetshenziswa Ngamabhuleki Ezimoto

(1) Impahla yokushayisana kwamabhuleki e-Asbestos: ukusebenza kahle okuphelele kokungqubuzana, indawo ephezulu yokuncibilika, amandla okusebenza aphezulu namandla okukhangisa aqinile enza imicu ye-asbestos igqame.Kusukela ngo-1970, ukuthuthukiswa kwayo kuye kwavinjelwa ukusebenza kabi kokudlulisa ukushisa nokwenyuka kokugqoka kwezinto ezibonakalayo.
(2) Insimbi-based non-asbestos friction material: I-brake friction material eyenziwe ngensimbi eshisiwe kanye nensimbi ehlukaniseke kahle yakhiwe ngale nto.I-iron calcined nethusi nezinye izinsimbi kunzima ukuhlukanisa futhi kulula ukuhlanganisa.ukungasebenzisi.Ngokuphambene nalokho, insimbi ehlukaniseke kahle yokushayisana kwamabhuleki eyenziwe ngethusi nensimbi ayisetshenziswa kabanzi ngenxa yezindleko zayo eziphakeme, izinyathelo zokukhiqiza ngokweqile, kanye nokwenza lula umsindo.
(3) I-semi-metal-based non-asbestos brake friction material: imicu ehlukahlukene engeyona eyensimbi nemicu yensimbi ithuthukisa kakhulu ukumelana nokungqubuzana kwezinto zamabhuleki, ngakho-ke zisetshenziswa kabanzi.Kodwa-ke, imicu yayo yensimbi kulula ukugqwala futhi iholela ekugugeni okungathi sína futhi ezinye izinkinga zisagxile ocwaningweni lochwepheshe bazo zonke izigaba zokuphila.
(4) Izinto zokungqubuzana kwamabhuleki ezingezona ezensimbi ezingasekelwe ensimbi: izinto ezihlukene zekhabhoni/ikhabhoni zinqoba ngamandla azo amahle kakhulu wokungqubuzana kanye nokumelana nokugoba okuphezulu.Kodwa intengo ephezulu futhi ikhawulela ukukhuthazwa kwayo.Emazweni ngamazwe, izwe lami lisesimeni esihamba phambili ekulungiseni izinto ezihlukahlukene ze-carbon/carbon brake.
(5) Izinto ezihlukahlukene zokushayisana kwamabhuleki emkhakheni wobunjiniyela be-ceramics: izici zezinga eliphansi lokuguga, amandla aphezulu okushisa kanye ne-anti-friction kuye kwaholela abacwaningi abaningi ukuba basebenzise le nto ye-inorganic non-metallic ukwakha izinto zamabhuleki, futhi inqubekelaphambili isiyenziwe. .Kodwa-ke, ukungalungi kwayo kokuphulwa kalula nakho kukhawulela isikhala sayo sohlelo.

Ukuthuthukiswa komkhuba wezinto ezifuywayo zamabhuleki ezimoto

Njengamanje, idizayini yokwakheka kwezinto kuseyisiqalo socwaningo lwezinto zokushayisana kwamabhuleki ezimoto.Nakuba izindlela zihluka emazweni ngamazwe, ukuthuthukisa ukusebenza kwezinto ezintsha zokungqubuzana nokuhlangabezana nezidingo zokuvikelwa kwemvelo kusewumgomo omkhulu.Ngaphansi kokuqondisa kwethiyori yentuthuko esimeme, ukugxila ekuthuthukisweni kwezinto zokushayisana kwamabhuleki bekulokhu kuthuthukela enkambisweni yomsindo ophansi futhi akukho kungcola.Lokhu kuthuthukiswa kuhambisana nokuthambekela kwamanje kanye nezidingo zomphakathi.Ngokuthuthuka okusheshayo kobuchwepheshe bokukhiqiza, Ukuthuthukiswa kwezinto zokubopha imoto kuzokhombisa izici ezihlukene.Izinto zamabhuleki ezihlukene zingakhethelwa izimoto ezinesimo sezulu esihlukene, izifunda kanye nemisebenzi.Ngale ndlela, ukusebenza kwe-braking yemoto kungadlala ukusebenza okuphezulu nokusebenza kahle kakhulu kwe-braking effect.

Ngaphansi kwezimo ezijwayelekile, ukuthuthuka kwesayensi nobuchwepheshe kuyisiqinisekiso sokwenziwa kahle kanye nokuhlukahluka kwezinto zokushayisana kwamabhuleki, futhi kungahlangabezana nezidingo zemboni yezimoto.Ukushiyeka kwe-fiber eyodwa eqinisiwe akunakugwenywa, indawo ebushelelezi ye-glass fiber inzima ukungena nge-resin;impahla yensimbi kunzima ukugwema inkinga yokugqwala;I-carbon material iyinkimbinkimbi ekusebenzeni, intengo ephezulu, futhi kunzima ukuyikhuthaza.Ngakho-ke, imicu ye-hybrid isiphenduke into egxile kakhulu ocwaningweni emazweni ahlukahlukene.Imicu yensimbi, imicu ye-carbon, imicu yekhabhoni nemicu yethusi ingasebenzisa izinzuzo ezihlukahlukene, inikeze ukudlala ngokugcwele izinzuzo zemicu, yehlise izindleko, futhi ithuthukise ukusebenza.Ukuze kuxazululwe inkinga ye-phenolic resin ngaphansi kwesenzo sokushisa okuphezulu, amabhizinisi amaningi nezikhungo zocwaningo lwesayensi zisebenzisa ezinye izinto zokusetshenziswa ezinhle kakhulu ezifana ne-butylbenzene ukwenza i-phenolic resin ihluke kunangaphambili ngocwaningo lwazo olusebenzayo kanye nentuthuko.Ngakho-ke, i-phenolic resin ebuyekeziwe enjalo iphinde ibe isiqondiso esisha socwaningo nokuthuthukiswa kwezinto zokushayisana kwamabhuleki ezimoto.

Fingqa

Ukufingqa, ukuthuthukiswa kwezinto zokushayisana kwamabhuleki ezimoto kuvela ngokulandelana ekuthuthukisweni kwezimoto, okubambe iqhaza ekuthuthukiseni ukusebenza kwamabhuleki ezimoto.Ngokuthuthukiswa kobuchwepheshe obusha nezinto ezintsha, umkhuba wokuthuthukiswa kwezinto zokushayisana kwamabhuleki ezimoto uzokhombisa ukuhlukahluka kanye nokusetshenziswa okuphansi, futhi ukuthuthukiswa kobuchwepheshe bezinto ezibonakalayo kuzothuthukisa kakhulu ukuthuthukiswa kwezinto zokushayisana kwamabhuleki ezimoto.
