Ukwenza ii-brake pads ezikumgangatho ophezulu, kukho iindawo ezimbini ezibalulekileyo: ipleyiti yangasemva kunye nezinto eziluhlaza. Ekubeni izinto eziluhlaza (i-friction block) ziyinxalenye echukunyiswa ngqo yidiski yebrake, uhlobo lwayo kunye nomgangatho wayo zidlala indima ebalulekileyo ekusebenzeni kwee-brake. Enyanisweni, kukho amakhulu eentlobo zezinto eziluhlaza kwimarike, kwaye asinakukwazi ukubona uhlobo lwezinto eziluhlaza ngokwembonakalo yee-brake pads. Ngoko ke sizikhetha njani izinto eziluhlaza ezifanelekileyo zokuvelisa? Masiqale sazi udidi oluqhelekileyo lwezinto eziluhlaza:
Iphakheji yezinto eziluhlaza
Izinto ezisetyenziswayo zingahlulwa zibe ziintlobo ezine:
1. Uhlobo lwe-asbestos:Izinto zokuqala ezisetyenzisiweyo kwiibrake pads zidlale indima ekuphuculeni amandla. Ngenxa yexabiso lazo eliphantsi kunye nokumelana nobushushu obuphezulu, zisetyenziswa kakhulu. Nangona kunjalo, izinto ze-asbestos zibonakaliswe njengeCarcinogen luluntu lwezonyango kwaye ngoku azivumelekanga kumazwe amaninzi. Uninzi lweemarike azivumeli ukuthengiswa kweebrake pads ezine-asbestos, ngoko ke kungcono ukukuphepha oku xa uthenga izinto eziluhlaza.
2. Uhlobo lwe-semi-metallic:Ngokwembonakalo yayo, inemicu emincinci kunye namasuntswana amancinci, anokwahlulwa ngokulula kwiintlobo ze-asbestos kunye ne-NAO. Xa kuthelekiswa nezinto zebrake zemveli, isebenzisa kakhulu izinto zesinyithi ukwandisa amandla eebrake pads. Kwangaxeshanye, ukumelana nobushushu obuphezulu kunye nokukwazi ukusasaza ubushushu nako kungaphezulu kunezixhobo zemveli. Nangona kunjalo, ngenxa yomxholo ophezulu wesinyithi wezinto zebrake pad, ingakumbi kwiindawo ezinobushushu obuphantsi, inokubangela ukuguguleka komphezulu kunye nengxolo phakathi kwebrake disc kunye nebrake pad ngenxa yoxinzelelo olukhulu lwebrake.
3. Uhlobo oluphantsi lwesinyithi:Ngokwembonakalo, ii-brake pads zentsimbi ephantsi zifana kancinci nee-brake pads zentsimbi encinci, ezineefayibha ezincinci kunye namasuntswana. Umahluko kukuba olu hlobo lunomxholo wentsimbi ophantsi kune-semi metal, nto leyo esombulula ingxaki yokuguguleka kwediski yebrake kwaye inciphisa ingxolo. Nangona kunjalo, ixesha lokuphila kwee-brake pads liphantsi kancinci kunelee-brake pads zentsimbi encinci.
4. Uhlobo lwe-ceramic:Iibrake pads zale fomula zisebenzisa uhlobo olutsha lwezinto zeseramikhi ezinobunzima obuphantsi, ukumelana nobushushu obuphezulu, kunye nokumelana nokuguguleka, ezineenzuzo zokungabi nangxolo, uthuli oluphumayo, ukungagqwali kwehabhu yamavili, ubomi obude benkonzo, kunye nokukhuselwa kwendalo. Okwangoku, ixhaphake kakhulu kwiimarike zaseMntla Melika, eYurophu naseJapan. Ukwehla kobushushu bayo kungcono kuneebrake pads ze-semi metallic, kwaye into ephambili kukuba iphucula ubomi obuqhelekileyo benkonzo yeebrake pads kwaye ayinangcoliseko. Olu hlobo lwebrake pad lunamandla okukhuphisana kwimarike kwiminyaka yakutshanje, kodwa ixabiso liza kuba phezulu nakwezinye izinto.
Ungakhetha njani izinto ezisetyenzisiweyo?
Uhlobo ngalunye lwezinto eziluhlaza lunezinto ezininzi ezahlukeneyo, ezifana ne-resin, umgubo wokungqubana, i-fiber yentsimbi, i-aramid fiber, i-vermiculite njalo njalo. Ezi zinto ziya kuxutywa ngokulinganayo kwaye zifumane izinto eziluhlaza zokugqibela esizifunayo. Sele singenise izinto eziluhlaza ezine ezahlukeneyo kwisicatshulwa esidlulileyo, kodwa zeziphi izinto eziluhlaza ekufuneka abavelisi bazikhethe kwimveliso? Enyanisweni, abavelisi kufuneka babe nokuqonda okucokisekileyo kwimarike abafuna ukuyithengisa ngaphambi kokuba bavelise ngobuninzi. Kufuneka sazi ukuba zeziphi ii-brake pads zezinto eziluhlaza ezidumileyo kwimarike yasekuhlaleni, zithini iimeko zendlela zasekuhlaleni, kwaye nokuba zigxila ngakumbi kwingxaki yokumelana nobushushu okanye yengxolo. Zonke ezi zinto kufuneka ziqwalaselwe.
Inxalenye yezinto eziluhlaza
Ngokuphathelele abavelisi abakhulileyo, baya kuhlala bephuhlisa iifomyula ezintsha, bongeze izixhobo ezintsha eziphambili kwifomyula okanye batshintshe umlinganiselo wento nganye ukuze ii-brake pads zisebenze ngcono. Kule mihla, imakethi ikwabonakala nezinto ze-carbon-ceramic ezisebenza ngcono kunohlobo lwe-ceramic. Abavelisi kufuneka bakhethe izinto eziluhlaza ngokweemfuno zokwenyani.
