Ama-brake pads angenye yezingxenye ezibaluleke kakhulu zokuphepha zesistimu yamabhuleki emoto.Ama-brake pads abamba iqhaza elikhulu ekubhulekeni, ngakho kuthiwa ama-brake pads avikela abantu nezimoto.
Isigubhu samabhuleki sifakwe izicathulo zamabhuleki, kodwa uma abantu bebiza ama-brake pads, babhekisela kuma-brake pads nezicathulo zamabhuleki ngokuvamile.
Igama elithi “ama-disc brake pads” libhekise ngqo kuma-brake pads afakwe kuma-disc brakes, hhayi ama-brake disc.
Ama-brake pads aqukethe izingxenye ezintathu eziyinhloko: i-steel backing (i-backing plate), i-adhesive, kanye ne-friction block.Ingxenye ebaluleke kakhulu i-friction block, okungukuthi ifomula ye-friction block.
Ifomula yempahla yokungqubuzana ngokuvamile yakhiwa izinhlobo eziyi-10-20 zezinto ezingavuthiwe.Ifomula iyahlukahluka kumkhiqizo kuye komunye, futhi ukuthuthukiswa kwefomula kusekelwe kumingcele ethile yezobuchwepheshe yemodeli.Abakhiqizi bezinto ezibonakalayo zefriction bagcina amafomula abo eyimfihlo emphakathini.
Ekuqaleni i-asbestos yayisebenza kahle kakhulu, kodwa ngemva kokuba sekwaziwa ukuthi imicu ye-asbestos iyingozi empilweni, le nto yathathelwa indawo eminye imicu.Namuhla, ama-brake pads ekhwalithi akufanele aqukathe i-asbestos, futhi hhayi lokho kuphela, kufanele futhi agweme insimbi ephezulu, imicu yokusebenza ebizayo futhi engaqinisekile kanye nama-sulfide ngangokunokwenzeka.Izinkampani ze-Friction materials umsebenzi wesikhathi eside ukuqhubeka nokuthuthukisa izinto ezintsha ukuze kuthuthukiswe ukusebenza kwezinto ezingqubuzanayo, ukuvikelwa kwemvelo kanye nomnotho.
Impahla ye-Friction iyinhlanganisela ekwakhiwa kwayo kokwakheka okuyisisekelo: i-adhesive: 5-25%;i-filler: 20-80% (kuhlanganise nesilungisi se-friction);i-fibre yokuqinisa: 5-60%
Iqhaza le-binder ukuhlanganisa izingxenye zezinto ezibonakalayo.Inokumelana nezinga lokushisa okuhle namandla.Ikhwalithi ye-binder inethonya elikhulu ekusebenzeni komkhiqizo.Izibophezelo ikakhulukazi zihlanganisa
ama-thermosetting resins: ama-phenolic resins, ama-phenolic resins ashintshiwe, ama-resins akhethekile amelana nokushisa.
Irabha: Irabha yokwenziwa yerabha yemvelo
Ama-resin nama-rubber asetshenziswa ndawonye.
Ama-Friction fillers ahlinzeka futhi azinzise izakhiwo zokungqubuzana futhi anciphise ukuguga.
I-Friction filler: i-barium sulfate, i-alumina, i-kaolin, i-iron oxide, i-feldspar, i-wollastonite, i-iron powder, ithusi (impuphu), i-aluminium powder…
Isilungisi sokusebenza kwe-friction: i-graphite, i-friction powder, i-rubber powder, i-coke powder
I-reinforcing fibers inikeza amandla ezinto ezibonakalayo, ikakhulukazi esimweni sokushisa okuphezulu.
Imicu ye-Asbestos
Imicu ye-non-asbestos: imicu yokwenziwa, imicu yemvelo, imicu okungewona amaminerali, imicu yensimbi, imicu yengilazi, imicu ye-carbon
I-Friction ukumelana nokunyakaza phakathi kwezindawo zokuthintana zezinto ezimbili ezinyakazayo.
Amandla okushayisana (F) alingana nomkhiqizo we-coefficient of friction (μ) kanye nengcindezi ephozithivu (N) endaweni eqondile endaweni yokushayisana, evezwa ifomula yefiziksi: F=μN.Ohlelweni lwamabhuleki, yi-coefficient of friction phakathi kwe-brake pad ne-brake disc, futhi uN ingamandla asetshenziswa i-caliper piston ku-pad.
Uma i-coefficient of friction iba nkulu, amandla okushayisana aba makhulu.Kodwa-ke, i-coefficient of friction phakathi kwe-brake pad kanye ne-disc izoshintsha ngenxa yokushisa okuphezulu okukhiqizwa ngemva kokungqubuzana, okusho ukuthi i-coefficient of friction iyashintsha ngokushintsha kwezinga lokushisa, futhi i-brake pad ngayinye ine-coefficient ehlukile yejika lokushintsha i-friction. ngenxa yezinto ezihlukahlukene, ama-brake pad ahlukene anamazinga okushisa ahlukene asebenza kahle kanye namazinga okushisa okusebenza asebenzayo.
Inkomba yokusebenza ebaluleke kakhulu yama-brake pads yi-coefficient of friction.I-coefficient kazwelonke yokushayisana kwamabhuleki iphakathi kuka-0.35 no-0.40.Uma i-coefficient ye-friction ingaphansi kuka-0.35, amabhuleki azodlula ibanga eliphephile lokubhuleka noma aze ahluleke, uma i-coefficient yokushayisana ingaphezu kuka-0.40, amabhuleki azothambekela ekubambeni kungazelelwe kanye nezingozi zokugingqika.
Ungakala kanjani ubuhle bama-brake pads

Mayelana nomsindo wamabhuleki
Umsindo wamabhuleki uyinkinga yesistimu yokubhuleka futhi ingase ihlobane nazo zonke izingxenye zesistimu yokubhuleka;akekho osatholile ukuthi iyiphi ingxenye yenqubo yokubhuleka ephusha umoya ukuze wenze umsindo wamabhuleki.
- Umsindo ungase uvele ekungqubuzaneni okungalingani phakathi kwama-brake pads nama-brake disc futhi ukhiqize ukudlidliza, amaza omsindo alokhu kudlidliza angabonakala umshayeli emotweni.Umsindo we-0-50Hz ophansi awubonwa emotweni, abashayeli bomsindo we-500-1500Hz ngeke bawubheke njengomsindo wamabhuleki, kodwa abashayeli bomsindo we-1500-15000Hz bazowubheka njengomsindo wamabhuleki.Okubalulekile okuwuphawu lomsindo wamabhuleki kubalwa ingcindezi yamabhuleki, izinga lokushisa lephedi yokushayisana, isivinini semoto kanye nesimo sezulu.
- Ukuxhumana kwe-friction phakathi kwama-brake pads nama-brake discs kuwukuthintana kwamaphuzu, enqubweni yokungqubuzana, indawo ngayinye yokuxhumana yokungqubuzana ayiqhubeki, kodwa ukushintshanisa phakathi kwamaphuzu, lokhu kushintshana kwenza inqubo yokungqubuzana ihambisane nokudlidliza okuncane, uma uhlelo lwe-braking lungakwazi amunca kahle ukudlidliza, ngeke kubangele umsindo wamabhuleki;Ngokuphambene nalokho, uma uhlelo lokubhuleka luzokhulisa ngempumelelo ukudlidliza, noma i-resonance, kungenzeka Ngokuphambene nalokho, uma isistimu yebhuleki ikhulisa ukudlidliza ngokuphumelelayo, noma ikhiphe ne-resonance, ingase ikhiqize umsindo wamabhuleki.
- Ukwenzeka komsindo wamabhuleki akwenzeki, futhi isisombululo samanje kungaba ukulungisa kabusha isistimu yamabhuleki noma ukushintsha ngokuhlelekile ukwakheka kwezingxenye ezifanele, okuhlanganisa, vele, ukwakheka kwamabhuleki.
- Kunezinhlobo eziningi zomsindo ngesikhathi sokubhuleka, ezingahlukaniswa ngokuthi: umsindo ukhiqizwa ngesikhathi sokubhuleka;umsindo uhambisana nayo yonke inqubo yokubhuleka;umsindo uvela lapho ibhuleki likhululwa.
I-Santa Brake, njengefekthri ekhiqiza amabhuleki ochwepheshe e-China, ingahlinzeka amakhasimende ngemikhiqizo esezingeni eliphezulu yokwenza amabhuleki njenge-semi-metallic, ceramic kanye nensimbi ephansi.
