Ukwenza iipakethi ezikumgangatho ophezulu, kukho iindawo ezimbini ezibalulekileyo: ipleyiti yangasemva kunye nemathiriyeli ekrwada.Ekubeni imathiriyeli ekrwada (ibhloko yefriction) yinxalenye echaphazela ngokuthe ngqo i-disc ye-brake, luhlobo kunye nomgangatho udlala indima ebalulekileyo ekusebenzeni kwe-brake.Ngapha koko, kukho amakhulu eentlobo zezinto ezikrwada kwimarike, kwaye asinakukwazi ukuxelela uhlobo lwemathiriyeli ekrwada ngokwenkangeleko yeebrake pads.Ngoko ke sikhetha njani izixhobo ezifanelekileyo zokuvelisa?Masiqale sazi ulwahlulo olurhabaxa lwemathiriyeli ekrwada:
Ipakethe yemathiriyeli ekrwada
Iimathiriyeli ekrwada zingohlulwa zibe ziindidi ezi-4:
1.Udidi lweAsbestos:Izinto zokuqala ezikrwada ezazisetyenziswa kwi-brake pads zadlala indima ekuphuculeni amandla.Ngenxa yexabiso eliphantsi kunye nokumelana nobushushu obuphezulu, isetyenziswa ngokubanzi.Nangona kunjalo, izinto ze-asbestos zibonakaliswe njengeCarcinogen luluntu lwezonyango kwaye ngoku aluvumelekanga kumazwe amaninzi.Uninzi lweemarike azivumeli ukuthengiswa kwee-brake pads eziqukethe i-asbestos, ngoko ke kungcono ukukuphepha oku xa kuthengwa izinto eziluhlaza.
2.Udidi lweSemi-metallic:Ukusuka kwimbonakalo, inemicu emihle kunye neengqungquthela, ezinokuthi zihluke ngokulula kwiintlobo ze-asbestos kunye ne-NAO.Xa kuthelekiswa nezixhobo ze-brake zemveli, ikakhulu isebenzisa izinto zetsimbi ukunyusa amandla eepakethi zebrake.Ngelo xesha, ukuxhathisa ubushushu obuphezulu kunye nokukwazi ukutshatyalaliswa kobushushu kuphezulu kwizinto zemveli.Nangona kunjalo, ngenxa yomxholo ophezulu wesinyithi we-brake pad material, ngokukodwa kwiindawo eziphantsi kweqondo lokushisa, kunokubangela ukugqoka okuphezulu kunye nengxolo phakathi kwe-disc ye-brake kunye ne-brake pad ngenxa yoxinzelelo olugqithisileyo.
3.Udidi lwentsimbi ephantsi:Ukusuka kwinkangeleko, i-metallic brake pads ephantsi ifana ne-semi-metallic brake pads, enemicu emihle kunye namasuntswana.Umahluko kukuba olu hlobo lunomxholo ophantsi wetsimbi kune-semi-metal, esombulula ingxaki yokugqoka i-brake disc kunye nokunciphisa ingxolo.Nangona kunjalo, ubomi beepakeki zebrake bungaphantsi kancinane kunobo be-semimetallic brake pads.
4.Udidi lweCeramic:Iipakeki zale fomyula zisebenzisa uhlobo olutsha lwemathiriyeli ye-ceramic enoxinano oluphantsi, ukumelana nobushushu obuphezulu, kunye nokumelana nokunxiba, okunezibonelelo zokungangxoli, kungabikho luthuli, akukho mhlwa kwihabhu yevili, ubomi benkonzo ende, kunye nokusingqongileyo. ukhuselo.Okwangoku, ixhaphakile kwiimarike zaseMntla Melika, eYurophu naseJapan.Ukudodobala kobushushu bayo kubhetele kunoko kwe-semimetallic brake pads, kwaye eyona nto iphambili kukuba iphucula ubomi obuqhelekileyo benkonzo yeebrake pads kwaye ayingcolisekanga.Olu hlobo lwe-brake pad lunokhuphiswano oluqinileyo lwemarike kwiminyaka yakutshanje, kodwa ixabiso liya kuba phezulu kunezinye izinto.
Indlela yokukhetha izinto eziphathekayo?
Uhlobo ngalunye lwemathiriyeli ekrwada lunezinto ezininzi ezahlukeneyo, ezinje ngeresin, umgubo wokukhuhlana, ifayibha yentsimbi, ifayibha yearamid, ivermiculite njalo njalo.Ezi zixhobo ziya kuxutywa ngomlinganiselo osisigxina kwaye zifumane imathiriyeli ekrwada yokugqibela esiyidingayo.Sele sazise izinto ezine eziluhlaza ezahlukeneyo kwisicatshulwa sangaphambili, kodwa zeziphi izinto eziluhlaza ekufuneka abavelisi bazikhethe kwimveliso?Ngapha koko, abavelisi kufuneka babe nokuqonda ngokupheleleyo imarike abafuna ukuyithengisa phambi kokuveliswa kobuninzi.Kufuneka sazi ukuba zeziphi iiphedi zebrake zezinto ezikrwada zithandwa kakhulu kwimarike yendawo, zeziphi iimeko zendlela zalapha, nokuba zijolise ngakumbi ekuxhathiseni ubushushu okanye ingxaki yengxolo.Zonke ezi zinto kufuneka zithathelwe ingqalelo.
Inxalenye yemathiriyeli ekrwada
Ngokuphathelele abavelisi abaqolileyo, baya kuthi ngokuqhubekayo baphuhlise iifomula ezintsha, bongeze imathiriyeli entsha ephucukileyo kwifomula okanye batshintshe ubungakanani bemathiriyeli nganye ukwenza iibhreke pads zisebenze ngcono.Kule mihla, imakethi iphinda ibonakale imathiriyeli ye-carbon-ceramic esebenza ngcono kunohlobo lweceramic.Abavelisi kufuneka bakhethe imathiriyeli ekrwada ngokweemfuno zokwenyani.
