Ngokuqhelekileyo, i-coefficient ye-friction ye-brake pads eqhelekileyo imalunga ne-0.3 ukuya kwi-0.4, ngelixa i-coefficient ye-friction ye-high-performance coefficient ye-brake pads i malunga ne-0.4 ukuya kwi-0.5.Ngomlinganiso ophezulu wokukhuhlana, unokuvelisa amandla amaninzi okuqhobosha ngamandla amancinci okunyovwa, kwaye ufezekise isiphumo esingcono sokunyathela.Kodwa ukuba i-coefficient ye-friction iphezulu kakhulu, iya kuyeka ngokukhawuleza ngaphandle kokunciphisa xa unyathela iibhuleki, engeyiyo imeko efanelekileyo.
Ke into ebalulekileyo kukuba kuthatha ixesha elingakanani ukufikelela kwixabiso elifanelekileyo leentsimbi ze-brake pad emva kokufaka iziqhoboshi kwasekuqaleni.Umzekelo, iipakethi zeebhuleki ezinomsebenzi olambathayo kunzima ukuphumeza isiphumo sokunyathela iziqhoboshi nasemva kokunyathela iziqhoboshi, nto leyo ebizwa ngokuba yintsebenzo engalunganga yokuqala.Okwesibini kukuba ukusebenza kwe-brake pad akuchaphazeli ukushisa.Oku nako kubaluleke kakhulu.Ngokubanzi, kwiqondo lobushushu eliphantsi kunye ne-ultra-high i-friction coefficient iya kuba nomkhwa wokunciphisa.Ngokomzekelo, i-coefficient of friction iyancipha xa imoto yogqatso ifikelela kwiqondo lokushisa eliphezulu kakhulu, elinemiphumo emibi.Ngamanye amazwi, xa ukhetha i-brake pads for racing, kubalulekile ukujonga ukusebenza kumaqondo okushisa aphezulu kunye nokukwazi ukugcina ukusebenza kwe-braking ezinzileyo ukususela ekuqaleni ukuya ekupheleni kogqatso.Inqaku lesithathu kukukwazi ukugcina uzinzo xa kwenzeka utshintsho lwesantya.
I-coefficient ye-brake pad friction iphezulu kakhulu okanye iphantsi kakhulu iya kuchaphazela ukusebenza kwe-braking.Ngokomzekelo, xa imoto ibhobhoza ngesantya esiphezulu, i-coefficient ye-friction iphantsi kakhulu kwaye iibhuleki aziyi kuba buthathaka;i-friction coefficient iphezulu kakhulu kwaye amatayara aya kubambelela, ebangela ukuba isithuthi sibe nomsila kunye nokutyibilika.Lo mbuso ungasentla uza kubangela ingozi enkulu kukhuseleko lokuqhuba.Ngokwemigangatho kazwelonke, ubushushu obufanelekileyo bokusebenza kweephedi zokukhuhlana kweebhuleki ze-100 ~ 350 ℃.Umgangatho ophantsi we-friction pads kwiqondo lobushushu lifikelela kuma-250 ℃, i-coefficient yayo ye-friction iya kuhla ngokukhawuleza, xa i-brake iya kuphuma ngokupheleleyo.Ngokomgangatho we-SAE, abavelisi be-brake friction pad baya kukhetha i-coefficient yokulinganisa i-FF, oko kukuthi, i-coefficient yokulinganisa i-0.35-0.45.
Ngokubanzi, iinkcukacha zobuchwephesha zeebhuleki eziqhelekileyo zibekwe malunga ne-300 ° C ukuya kuma-350 ° C ukuqalisa ukuhla kobushushu;ngelixa iiphedi zokuqhobosha ziphezulu malunga nama-400°C ukuya kuma-700°C.Ukongeza, izinga lokudodobala kobushushu kwiibhuleki zeemoto zomdyarho libekwe phezulu kangangoko ukugcina i-coefficient ethile yokukhuhlana nokuba ukudodobala kobushushu kuyaqala.Ngokuqhelekileyo, izinga lokudodobala kobushushu kwiipakethi zebrake eziqhelekileyo yi-40% ukuya kuma-50%;izinga lokudodobala kobushushu bokusebenza okuphezulu kweepakedi zebrake yi-60% ukuya kuma-80%, nto leyo ethetha ukuba i-coefficient yokukhuhlana kweepakeki eziqhelekileyo phambi kokuhla kobushushu kunokugcinwa nasemva kokwehla kobushushu.Abavelisi be-Brake pad bebesebenza kuphando kunye nophuhliso lokwakheka kweresin, umxholo wayo, kunye nezinye izixhobo zefibrous ukuze kuphuculwe indawo yokudodobala kobushushu kunye nesantya sokwehla kobushushu.
I-Santa Brake ityale imali eninzi kuphando kunye nophuhliso lwe-brake pad formulations kule minyaka idlulileyo, kwaye ngoku yenze inkqubo epheleleyo yokuqulunqa i-semi-metallic, i-ceramic, kunye ne-low-metallic, enokuthi ivumelane neemfuno ezahlukeneyo ezahlukeneyo. abathengi kunye neendawo ezahlukeneyo.Siyakwamkela ukuba ubuze malunga neemveliso zethu okanye undwendwele umzi-mveliso wethu.
