Imvamisa, i-coefficient ye-friction yama-brake pads ajwayelekile icishe ibe ngu-0.3 kuya ku-0.4, kuyilapho i-coefficient yokushayisana yama-brake pads asebenza kahle icishe ibe ngu-0.4 kuya ku-0.5.Nge-coefficient ephezulu yokushayisana, ungakha amandla amaningi okubhuleka ngamandla amancane okugwedla, futhi uzuze umphumela ongcono wokubhuleka.Kodwa uma i-friction coefficient iphezulu kakhulu, izoma kungazelelwe ngaphandle kokugoba lapho unyathela amabhuleki, nakho okungesona isimo esihle.
Ngakho-ke into ebalulekile ukuthi kuthatha isikhathi esingakanani ukufinyelela inani elifanele le-coefficient ye-brake pad ngokwayo ngemva kokufaka amabhuleki kwasekuqaleni.Isibonelo, amabhuleki amabhuleki angasebenzi kahle anzima ukuthola umphumela wokubhuleka ngisho nangemva kokunyathela amabhuleki, okuvame ukubizwa ngokuthi ukungasebenzi kahle kokuqala kokubhuleka.Okwesibili ukuthi ukusebenza kwe-brake pad akuthintwa izinga lokushisa.Lokhu nakho kubaluleke kakhulu.Ngokuvamile, kumazinga okushisa aphansi kanye ne-ultra-high temperature friction coefficient izoba nokuthambekela kokunciphisa.Isibonelo, i-coefficient of friction iyancipha lapho imoto yomjaho ifinyelela izinga lokushisa eliphakeme kakhulu, elinemiphumela emibi.Ngamanye amazwi, lapho ukhetha ama-brake pads omjaho, kubalulekile ukubheka ukusebenza emazingeni okushisa aphezulu futhi ukwazi ukugcina ukusebenza kahle kwamabhuleki kusukela ekuqaleni kuze kube sekupheleni komjaho.Iphuzu lesithathu yikhono lokugcina uzinzo uma kwenzeka izinguquko zejubane.
I-coefficient ye-brake pad friction iphezulu kakhulu noma iphansi kakhulu izophazamisa ukusebenza kokubhuleka.Isibonelo, uma imoto ibhuleka ngesivinini esikhulu, i-coefficient ye-friction iphansi kakhulu futhi amabhuleki ngeke azwele;i-coefficient ye-friction iphezulu kakhulu futhi amathayi azobambelela, okwenza imoto imsila futhi itshibilike.Lesi simo esingenhla sizobeka ingozi enkulu ekuphepheni kokushayela.Ngokusho kwamazinga kazwelonke, izinga lokushisa elifanele le-brake friction pads ngu-100 ~ 350 ℃.Izinga eliphansi lama-brake friction pads ezingeni lokushisa lifinyelela ku-250 ℃, i-coefficient yayo ye-friction izokwehla kakhulu, lapho ibhuleki izobe ingasebenzi ngokuphelele.Ngokwezinga le-SAE, abakhiqizi bephedi yokushayisana kwamabhuleki bazokhetha i-coefficient yesilinganiso se-FF, okungukuthi, i-coefficient yesilinganiso sokungqubuzana esingu-0.35-0.45.
Ngokuvamile, ukucaciswa kobuchwepheshe bamabhuleki ajwayelekile asethwe cishe ku-300°C kuya ku-350°C ukuze kuqale ukwehla kokushisa;kuyilapho ama-brake pads asebenza kahle ecishe abe ngu-400°C kuya ku-700°C.Ngaphezu kwalokho, izinga lokwehla kokushisa kwamabhuleki ezimotweni zomjaho lisethwe phezulu ngangokunokwenzeka ukuze kugcinwe i-coefficient ethile yokungqubuzana ngisho noma ukwehla kokushisa kuqala.Imvamisa, izinga lokwehla kokushisa kwama-brake pads lingama-40% kuya ku-50%;izinga lokwehla kokushisa kwama-brake pads asebenza kahle kakhulu lingu-60% kuya ku-80%, okusho ukuthi i-coefficient yokushayisana yama-brake pads ngaphambi kokwehla kokushisa ingagcinwa ngisho nangemva kokwehla kokushisa.Abakhiqizi bephedi lamabhuleki bebesebenza ocwaningweni nasekuthuthukisweni kokwakheka kwe-resin, okuqukethwe kwayo, nezinye izinto ze-fibrous ukuze kuthuthukiswe indawo yokwehla kokushisa nezinga lokwehla kokushisa.
I-Santa Brake itshale imali eningi ocwaningweni nasekuthuthukisweni kokwakhiwa kwamabhuleki eminyakeni edlule, futhi manje isisungule uhlelo oluphelele lokuhlanganisa i-semi-metallic, ceramic, ne-low-metallic, engakwazi ukuzivumelanisa nezidingo ezahlukene amakhasimende kanye nezindawo ezahlukene.Siyakwamukela ukuthi ubuze ngemikhiqizo yethu noma uvakashele imboni yethu.
