Ukuze kwenziwe ama-brake pad asezingeni eliphezulu, kunezingxenye ezimbili ezibalulekile: ipuleti langemuva kanye nezinto zokusetshenziswa. Njengoba izinto zokusetshenziswa (i-friction block) ziyingxenye ethinta ngqo i-brake disc, uhlobo lwayo kanye nekhwalithi yayo kudlala indima ebalulekile ekusebenzeni kwama-brake. Eqinisweni, kunezinhlobo eziningi zezinto zokusetshenziswa emakethe, futhi asikwazi ukutshela uhlobo lwezinto zokusetshenziswa ngokuya ngokubukeka kwama-brake pad. Ngakho-ke sizikhetha kanjani izinto zokusetshenziswa ezifanele ukukhiqizwa? Ake siqale sazi ukuhlukaniswa kwezinto zokusetshenziswa:
Iphakheji yezinto zokusetshenziswa
Izinto zokusetshenziswa zingahlukaniswa zibe izinhlobo ezine:
1. Uhlobo lwe-asbestos:Izinto zokuqala ezisetshenziswa kuma-brake pad zidlale indima ekuthuthukiseni amandla. Ngenxa yentengo yazo ephansi kanye nokumelana nokushisa okuphezulu, isetshenziswa kabanzi. Kodwa-ke, izinto ze-asbestos ziye zafakazelwa ukuthi ziyingozi kumdlavuza ngumphakathi wezokwelapha futhi manje sezivinjelwe emazweni amaningi. Izimakethe eziningi azivumeli ukuthengiswa kwama-brake pad aqukethe i-asbestos, ngakho-ke kungcono ukugwema lokhu lapho uthenga izinto zokusetshenziswa.
2. Uhlobo lwe-semi-metallic:Ngokubukeka kwayo, inemicu emincane nezinhlayiya ezincane, ezingahlukaniswa kalula nezinhlobo ze-asbestos ne-NAO. Uma kuqhathaniswa nezinto zendabuko zamabhuleki, isebenzisa kakhulu izinto zensimbi ukwandisa amandla amabhuleki. Ngesikhathi esifanayo, ukumelana nokushisa okuphezulu kanye nekhono lokushabalalisa ukushisa nakho kuphakeme kunezinto zendabuko. Kodwa-ke, ngenxa yokuqukethwe kwensimbi okuphezulu kwezinto zebhuleki, ikakhulukazi ezindaweni eziphansi kwezinga lokushisa, kungabangela ukuguguleka kwendawo nomsindo phakathi kwediski yebhuleki kanye nebhuleki ngenxa yokucindezela okukhulu kwamabhuleki.
3. Uhlobo lwensimbi ephansi:Uma sibheka, ama-brake pad aphansi ensimbi afana kancane nama-brake pad aphansi ensimbi, anemicu emincane nezinhlayiya ezincane. Umehluko ukuthi lolu hlobo lunenani eliphansi lensimbi kune-semi metal, okuxazulula inkinga yokuguguleka kwediski yamabhuleki futhi kunciphisa umsindo. Kodwa-ke, isikhathi sokuphila sama-brake pad siphansi kancane kunesama-brake pad aphansi ensimbi.
4. Uhlobo lwe-Ceramic:Ama-brake pad ale fomula asebenzisa uhlobo olusha lwezinto ze-ceramic ezinobukhulu obuphansi, ukumelana nokushisa okuphezulu, kanye nokumelana nokuguguleka, ezinezinzuzo zokungabi nomsindo, uthuli oluwayo, ukungagqwali kwehabhu lamasondo, impilo yesevisi ende, kanye nokuvikelwa kwemvelo. Njengamanje, kuvame kakhulu ezimakethe zaseNyakatho Melika, eYurophu, naseJapan. Ukwehla kokushisa kwayo kungcono kunokwama-brake pad ensimbi, futhi into eyinhloko ukuthi ithuthukisa impilo yesevisi evamile yama-brake pad futhi ayinakho ukungcola. Lolu hlobo lwe-brake pad lunokuncintisana okukhulu emakethe eminyakeni yamuva nje, kodwa intengo nayo ibizoba phezulu kunezinye izinto.
Ungakhetha kanjani izinto zokusetshenziswa?
Uhlobo ngalunye lwezinto zokusetshenziswa lunezinto eziningi ezahlukene, njenge-resin, i-friction powder, i-fibre yensimbi, i-aramid fiber, i-vermiculite njalo njalo. Lezi zinto zizoxutshwa ngesilinganiso esinqunyiwe futhi zithole izinto zokusetshenziswa zokugcina esizidingayo. Sesivele sethule izinto zokusetshenziswa ezine ezahlukene embhalweni odlule, kodwa yiziphi izinto zokusetshenziswa okufanele abakhiqizi bazikhethe ekukhiqizeni? Eqinisweni, abakhiqizi kufanele babe nokuqonda okujulile ngemakethe abafuna ukuyithengisa ngaphambi kokukhiqizwa ngobuningi. Sidinga ukwazi ukuthi yimaphi ama-brake pad ezinto zokusetshenziswa athandwa kakhulu emakethe yendawo, yiziphi izimo zomgwaqo wendawo, nokuthi ngabe agxila kakhulu enkingeni yokumelana nokushisa noma yomsindo. Zonke lezi zici kufanele zicatshangelwe.
Ingxenye yezinto zokusetshenziswa
Ngokuqondene nabakhiqizi abavuthiwe, bazoqhubeka nokuthuthukisa amafomula amasha, bangeze izinto ezintsha ezithuthukisiwe kufomula noma bashintshe isilinganiso sezinto ngayinye ukuze benze ama-brake pad asebenze kangcono. Namuhla, imakethe ibuye ivele nezinto ze-carbon-ceramic ezisebenza kangcono kunohlobo lwe-ceramic. Abakhiqizi badinga ukukhetha izinto zokusetshenziswa ngokwezidingo zangempela.
