Ceramic brake pads ndi mtundu wa brake pad yomwe imaphatikizapo mineral fiber, aramid fiber ndi ceramic fiber (chifukwa zitsulo zachitsulo zimatha dzimbiri, kutulutsa phokoso ndi fumbi, choncho sizingakwaniritse zofunikira za mapangidwe amtundu wa ceramic).
Ogula ambiri poyamba amalakwitsa ngati ceramic ngati yopangidwa ndi ceramic, koma kwenikweni, ma brake pads amapangidwa kuchokera ku mfundo zazitsulo za ceramic m'malo mopanda zitsulo.Pakutentha kwambiri uku, pamwamba pa brake pad pamakhala sintered zitsulo-ceramic zofanana, kotero kuti brake pad imakhala yokhazikika pakutentha uku.Ma brake pads achikhalidwe samatulutsa kutentha uku, ndipo kuwonjezereka kwakukulu kwa kutentha kwapamwamba kumatha kupangitsa kuti zinthu zapamtunda zisungunuke kapena kutulutsa mpweya, zomwe zingayambitse kutsika kwakukulu kwa ma brake pambuyo pakuboola mosalekeza kapena kutaya kwathunthu. ya braking.
Ma ceramic brake pads ali ndi maubwino otsatirawa kuposa mitundu ina ya ma brake pads.
(1) Kusiyana kwakukulu pakati pa ma brake pads a ceramic ndi ma brake pads achikhalidwe ndikuti palibe chitsulo.M'mabotolo achikhalidwe, chitsulo ndicho chinthu chachikulu chomwe chimapanga mikangano, yomwe imakhala ndi mphamvu yothamanga kwambiri, koma imakonda kuvala komanso phokoso.Ma brake pads akaikidwa, sipadzakhala kukangana kwachilendo (mwachitsanzo, kukwapula) panthawi yoyendetsa bwino.Chifukwa ma brake pads a ceramic alibe zigawo zachitsulo, phokoso la ma brake pads achikhalidwe akusisita pakati pawo (ie ma brake pads ndi ma brake discs) amapewa.
(2) Khola lokhazikika lokhazikika.Friction coefficient ndiye chizindikiro chofunikira kwambiri pazambiri zilizonse zokangana, zomwe zimakhudzana ndi kuthekera kwabwino kapena koyipa kwa brake pads.M'kati mwa braking chifukwa cha kutentha komwe kumabwera chifukwa cha kukangana, kutentha kwa ntchito kumawonjezeka, kugwedezeka kwazitsulo za brake pad ndi kutentha, coefficient of friction imayamba kuchepa.Pogwiritsira ntchito kwenikweni, zidzachepetsa mphamvu yotsutsana, motero kuchepetsa mphamvu ya braking.Kukangana kwa ma brake pads wamba sikukhwima, ndipo kugundana kwamphamvu ndikokwera kwambiri kumayambitsa zinthu zosatetezeka monga kutayika kwa njira panthawi yoboola mabuleki, zowotcha zomata komanso ma brake discs.Ngakhale kutentha kwa diski ya brake ndipamwamba kwambiri mpaka madigiri a 650, friction coefficient of ceramic brake pads idakali pafupi ndi 0.45-0.55, yomwe ingathe kuonetsetsa kuti galimotoyo ili ndi braking yabwino.
(3) Ceramic imakhala ndi kukhazikika kwamafuta komanso kutsika kwamafuta, komanso kukana kwabwino.Kutentha kwa nthawi yayitali mu madigiri a 1000, khalidwe ili limapangitsa kuti ceramic ikhale yoyenera kwa zipangizo zosiyanasiyana zoboola, zomwe zimagwiritsidwa ntchito kwambiri, zimatha kukumana ndi brake pad high-liwiro, chitetezo, kukana kuvala kwakukulu ndi zofunikira zina zamakono.
(4) Lili ndi mphamvu zamakina abwino komanso zinthu zakuthupi.Imatha kupirira kukakamizidwa kwakukulu ndi kukameta ubweya.Zopangira zokhutiritsa mumsonkhano musanagwiritse ntchito, pamafunika kubowola, kusonkhana ndi kukonza makina ena, kuti mupange msonkhano wa brake pad.Chifukwa chake, zinthu zokangana ziyenera kukhala ndi mphamvu zokwanira zamakina kuti zitsimikizire kuti kukonza kapena kugwiritsa ntchito njirayo sikukuwoneka kusweka ndi kusweka.
(5) Kukhala ndi katundu wochepa kwambiri wowola ndi kutentha.
(6) Kupititsa patsogolo magwiridwe antchito a ma brake pads.Chifukwa cha kutentha kwachangu kwa zida za ceramic, zimagwiritsidwa ntchito popanga mabuleki, ndipo coefficient of friction yake ndi yapamwamba kuposa yazitsulo zopumira.
(7) Chitetezo.Ma brake pads amatulutsa kutentha kwambiri nthawi yomweyo akamaboola, makamaka pa liwiro lalikulu kapena pakatsika mwadzidzidzi.M'malo otentha kwambiri, friction coefficient ya friction pads imatsika, yotchedwa thermal recession.Wamba mabuleki ziyangoyango matenthedwe kuwonongeka otsika, kutentha kwambiri ndi mabuleki mwadzidzidzi pamene ananyema madzimadzi kutentha kumawonjezera kuti mabuleki kuchedwa, kapena imfa ya mabuleki zotsatira chitetezo chinthu ndi otsika.
(8) chitonthozo.Pakati pazizindikiro zotonthoza, eni ake nthawi zambiri amakhudzidwa kwambiri ndi phokoso la ma brake pads, kwenikweni, phokoso limakhalanso vuto lanthawi yayitali lomwe silingathetsedwe ndi ma brake pads wamba.Phokoso limapangidwa ndi kukangana kwachilendo pakati pa friction pad ndi friction disc, ndipo zifukwa za mbadwo wake ndizovuta kwambiri, monga mphamvu ya braking, kutentha kwa brake disc, liwiro lagalimoto ndi nyengo ndi zifukwa zonse zotheka phokoso.
(9) Makhalidwe abwino kwambiri azinthu.Ceramic brake pads amagwiritsa ntchito tinthu tating'ono ta graphite/mkuwa/advanced ceramic (non-asibesitosi) ndi theka-zitsulo ndi zida zina zapamwamba zokhala ndi kutentha kwambiri, kukana kuvala, kukhazikika kwa brake, kukonza ma brake disc, kuteteza chilengedwe, popanda phokoso lalitali. moyo wautumiki ndi zabwino zina, kuti mugonjetse zida zama brake pad ndi zolakwika zamachitidwe ndizovuta kwambiri padziko lonse lapansi zotsogola zapamwamba za ceramic brake pads.Kuphatikiza apo, kutsika kwa mpira wa ceramic slag ndi kuwongolera bwino kungathenso kuchepetsa kuvala kwa awiri ndi phokoso la ma brake pads.
(10) Moyo wautali wautumiki.Moyo wautumiki ndi chizindikiro cha nkhawa kwambiri.Moyo wautumiki wa ma brake pads wamba uli pansi pa 60,000 km, pomwe moyo wautumiki wa ma brake pads uli pamwamba pa 100,000 km.Ndicho chifukwa ceramic ananyema ziyango ntchito chilinganizo chapadera cha 1 kwa 2 mitundu ya electrostatic ufa, zipangizo zina ndi sanali malo amodzi zipangizo, kotero kuti ufa adzatengedwa ndi mphepo ndi kayendedwe ka galimoto, ndipo sadzamamatira. kwa gudumu likulu kuti zikhudze kukongola.Kutalika kwa moyo wa zida za ceramic ndizoposa 50% kuposa zazitsulo wamba.Mukatha kugwiritsa ntchito ma brake pads, sipadzakhalanso mipope (mwachitsanzo zokanda) pa ma brake discs, kukulitsa moyo wautumiki wa ma disc oyambilira ndi 20%.
