Mbiri yachisinthiko ya zida zama brake zamagalimoto

Kukula kwa zida zama brake zamagalimoto kumagawidwa m'magawo atatu otsatirawa: gawo loyamba ndi gawo la chitukuko cha zida zama brake, zomwe makamaka mabuleki a ng'oma;siteji yachiwiri ndi siteji ya chitukuko mofulumira ananyema zipangizo , Zida zambiri zatsopano zinayamba kubadwa.Gawo ili ndi brake yomwe imagwiritsa ntchito mabuleki a disc;siteji yachitatu ndi siteji pamene chuma ananyema akufotokozera kuti pachimake, ndipo siteji iyi ndi ananyema kuti makamaka amagwiritsa chimbale mabuleki, zosiyanasiyana zipangizo zatsopano zikutuluka mu mtsinje wosatha.

Muyezo waukadaulo komanso kapangidwe kazinthu zama brake friction

1.1 Miyezo Yaumisiri

Choyamba, zoyenera komanso zosalala zotsutsana ndi mikangano.Zoyenera komanso zokhazikika zotsutsana ndi mikangano zimatha kutsimikizira kukangana "kofewa".Chachiwiri, kwambiri mawotchi mphamvu ndi thupi katundu.Mphamvu zamakina zimatha kuwonetsetsa kuti zinthuzo sizingawonongeke ndikupewa zovuta zomwe zingabwere chifukwa cha kulephera kwa braking.Chachitatu, phokoso lochepa la braking.Pofuna kuteteza chilengedwe, phokoso la braking galimoto siliyenera kupitirira 85dB.Chachinayi, kuchepetsa kuvala pa chassis.Njira yopangira braking iyenera kupewa kuvala ndi kukwapula pa disk friction.

1.2 Kuphatikizika kwa zida za brake friction

Choyamba, organic binders.Phenolic resins ndi modified phenolic resins ndi mitundu iwiri yofunika kwambiri.Chachiwiri, zida zowonjezeredwa ndi CHIKWANGWANI.Zitsulo zachitsulo m'malo mwa asibesitosi monga chinthu chachikulu, ndipo zopangira mafuta, zodzaza ndi zosinthira mikangano zimayikidwa muzitsulo ndikusungunulidwa kuti apange zida zomangira ma sintered brake.Chachitatu, filler.Ma reagents ogwirizana omwe amapangidwa ndi ma reagents omwe amawongolera zinthu zokangana amapanga gawo ili.

1.3 Gulu la Zida Zabuleki Zagalimoto

(1) Asbestos brake friction material: kugundana kwabwino kokwanira, malo osungunuka kwambiri, mphamvu zamakina apamwamba komanso mphamvu yamphamvu yotsatsira imapangitsa kuti ulusi wa asibesitosi uwonekere.Kuyambira 1970, chitukuko chake chalephereka chifukwa cha kusamutsa kwa kutentha komanso kuchuluka kwa mavalidwe azinthu.
(2) Chitsulo chopanda asbestos cholimbana ndi ma brake friction: Chitsulo chophwanyika chopangidwa ndi chitsulo choyaka moto ndi chitsulo chogawanika bwino chimapangidwa ndi izi.Chitsulo chachitsulo ndi mkuwa ndi zitsulo zina zimakhala zovuta kuzilekanitsa komanso zosavuta kuziphatikiza.osagwiritsa ntchito.M'malo mwake, zitsulo zogawanika bwino zomangira zitsulo zopangidwa ndi mkuwa ndi chitsulo sizigwiritsidwa ntchito kwambiri chifukwa cha kukwera mtengo kwake, masitepe opangira kwambiri, komanso kupanga phokoso kosavuta.
(3) Semi-metal-based non-asbestos brake friction material: ulusi wosiyanasiyana wopanda zitsulo ndi ulusi wachitsulo umathandizira kwambiri kukana kwamphamvu kwa zida zoboola, motero zimagwiritsidwa ntchito kwambiri.Komabe, ulusi wake wachitsulo ndi wosavuta kuchita dzimbiri ndipo umapangitsa kuti munthu avulale kwambiri komanso mavuto ena akadali cholinga cha kafukufuku wa akatswiri amitundu yonse.
(4) Zopanda zitsulo zopangidwa ndi zitsulo zopanda asibesito zomwe zimawombana ndi mabuleki: zida zosiyanasiyana za carbon/carbon friction zimapambana ndi kuthekera kwawo kopambana komanso kukana kupindika kwambiri.Koma mtengo wapamwamba umachepetsanso kukwezedwa kwake.Padziko lonse lapansi, dziko langa lili pachiwonetsero chotsogola pantchito yokonza zida zosiyanasiyana za carbon/carbon brake.
(5) Zida zosiyanasiyana zolimbana ndi ma brake pagawo la zomangamanga zaumisiri: mawonekedwe a kutsika otsika, kutentha kwakukulu komanso kusagwirizana kwapangitsa ofufuza ambiri kugwiritsa ntchito zinthu zopanda chitsulo izi kupanga zida zoboola, ndipo kupita patsogolo kwachitika. .Komabe, kuipa kwake kosweka mosavuta kumachepetsanso malo ake ogwiritsira ntchito.

Kukula mchitidwe wa zipangizo zapakhomo magalimoto ananyema

Pakadali pano, kapangidwe kazinthu kakadakhala koyambira pakufufuza za zida zama brake zamagalimoto.Ngakhale kuti njirazi zimasiyana m’mayiko osiyanasiyana, kupititsa patsogolo kagwiritsidwe ntchito ka zinthu zatsopano zokangana ndi kukwaniritsa zofunikira zachitetezo cha chilengedwe ndicho cholinga chachikulu.Motsogozedwa ndi chiphunzitso chachitukuko chokhazikika, kutukuka kwa zida za brake friction kwakhala kukukulirakulira kutsata phokoso lotsika komanso lopanda kuyipitsa.Chitukukochi chikugwirizananso ndi zomwe zikuchitika panopa komanso zofunikira za anthu.Ndi chitukuko chofulumira chaukadaulo wopanga, Kukula kwa zida zama brake zamagalimoto kudzawonetsanso mawonekedwe osiyanasiyana.Zida zosiyanasiyana zama brake zimatha kusankhidwa pamagalimoto okhala ndi nyengo, zigawo ndi ntchito zosiyanasiyana.Mwanjira imeneyi, kuyendetsa galimoto kwagalimoto kumatha kuchita bwino kwambiri komanso kuchita bwino kwambiri.

Nthawi zonse, kupita patsogolo kwa sayansi ndi ukadaulo ndi chitsimikizo cha kukhathamiritsa ndi kusiyanasiyana kwa zida zomangira ma brake, komanso kutha kukwaniritsa zosowa zamagalimoto.Zofooka za fiber imodzi yokhayokha sizingalephereke, pamwamba pa galasi la galasi ndizovuta kulowa ndi utomoni;zinthu zachitsulo n'zovuta kupewa vuto la dzimbiri;zinthu za kaboni ndizovuta kwambiri, zokwera mtengo, komanso zovuta kuzilimbikitsa.Chifukwa chake, ma hybrid fibers akhala gawo lofufuza zamayiko osiyanasiyana.Ulusi wachitsulo, ulusi wa kaboni, ulusi wa kaboni ndi ulusi wamkuwa zimatha kutengera zabwino zosiyanasiyana, kupereka masewera olimbitsa thupi pazabwino za ulusi, kuchepetsa ndalama, ndikuwongolera magwiridwe antchito.Pofuna kuthetsa vuto la utomoni wa phenolic pansi pa kutentha kwakukulu, mabizinesi ambiri ndi mabungwe ofufuza asayansi amagwiritsa ntchito zida zina zabwino kwambiri monga butylbenzene kupanga utomoni wa phenolic wosiyana ndi wakale kudzera mu kafukufuku wawo komanso chitukuko.Chifukwa chake, utomoni wosinthidwa wa phenolic resin ulinso njira yatsopano yopangira kafukufuku ndi chitukuko cha zida zamagalimoto zama brake.

Fotokozerani mwachidule

Mwachidule, kakulidwe ka zida zama brake friction pamagalimoto zimawonekera motsatizana pakupanga magalimoto, zomwe zathandiza kwambiri pakuwongolera ma braking agalimoto.Ndi chitukuko cha matekinoloje atsopano ndi zida zatsopano, kakulidwe kazinthu zamagalimoto zama brake friction kuwonetsa kusiyanasiyana komanso kugwiritsa ntchito pang'ono, komanso kupititsa patsogolo ukadaulo wazinthu kumalimbikitsanso kwambiri chitukuko cha zida zama brake zamagalimoto.
