Ceramic brake pads amasokoneza lingaliro lachikhalidwe la ma brake pads, ma brake pads amapangidwa ndi ulusi wa ceramic, zinthu zopanda chitsulo, zomatira ndi chitsulo pang'ono.
Ceramic brake pads ndi mtundu wa ma brake pads, ogula ambiri amalakwitsa ngati ceramic poyamba, kwenikweni, ma brake pads a ceramic amachokera ku mfundo za ceramic m'malo mwa zitsulo zopangidwa ndi zitsulo, ma brake pads chifukwa cha kuthamanga kwambiri, kutentha kwambiri. Pamwamba pa mikangano, malinga ndi muyeso, imatha kufika madigiri 800 ~ 900, ndipo ena apamwamba kwambiri. Pa kutentha kwakukulu kumeneku, pamwamba pa brake pad idzakhala ndi zofanana zofanana ndi cermet sintering, kotero kuti brake pad imakhala yokhazikika pa kutentha uku. Ma brake pads achikhalidwe sangapangire sintering reaction pakutentha uku, chifukwa cha kukwera kwakukulu kwa kutentha kwapamwamba kumasungunula zinthu zapamtunda ndikutulutsa khushoni ya mpweya, zomwe zingayambitse kutsika kwambiri kwa ma brake kapena kutayika kwa mabuleki pambuyo pakuboola mosalekeza.
Zochita za Ceramic brake pad:
Fumbi lochepa pamagudumu; Moyo wautali wa mbale ndi awiriawiri; Palibe phokoso / palibe kugwedeza / palibe kuwonongeka kwa disc. Zochita zenizeni ndi izi:
(1) Kusiyana kwakukulu pakati pa ma brake pads ndi ma brake pads achikhalidwe ndikuti palibe chitsulo. Chitsulo muzitsulo zamtundu wa brake ndicho chinthu chachikulu chogwedeza, mphamvu ya braking ndi yayikulu, koma kuvala ndi kwakukulu, ndipo phokoso ndilosavuta kuwonekera. Pambuyo pa kukhazikitsa mapepala a ceramic brake pads mu kuyendetsa bwino, sipadzakhala phokoso lachilendo (ndiko kuti, kukanda phokoso). Chifukwa ma brake pads a ceramic alibe zida zachitsulo, phokoso lachitsulo pakati pa ma brake pads ndi magawo awiri (ndiko kuti, ma brake pads ndi brake disc) amapewa.
(2) Khola lokhazikika lokhazikika. Friction coefficient ndiye mlozera wofunikira kwambiri wazinthu zilizonse zogundana, zomwe zimagwirizana ndi mphamvu yama brake pads. M'kati mwa braking chifukwa cha kukangana komwe kumatulutsa kutentha, kuwonjezeka kwa kutentha kwa ntchito, ma brake pad friction amakhudzidwa ndi kutentha, kugunda kwapakati kumayamba kuchepa. Pochita ntchito, mikangano imachepetsedwa, motero kuchepetsa mphamvu ya braking. Kukangana kwa ma brake pads wamba sikukhwima, ndipo friction coefficient ndiyokwera kwambiri, zomwe zimapangitsa kuti pakhale zinthu zosatetezeka monga kutayika kwa mayendedwe, kuyaka, komanso kukwapula kwa ma brake discs panthawi ya braking. Ngakhale kutentha kwa chimbale cha brake kufika madigiri a 650, friction coefficient ya ceramic brake pad idakali pafupi ndi 0.45-0.55, yomwe ingatsimikizire kuti galimotoyo ili ndi ntchito yabwino ya braking.
(3) Ma Ceramics ali ndi kukhazikika kwamafuta abwino komanso kutsika kwamafuta otsika, kukana kwabwino. Kutentha kwanthawi yayitali ndi madigiri a 1000, zomwe zimapangitsa kuti ceramic ikhale yoyenera pakuchita bwino kwa zida zosiyanasiyana zama brake, ndipo imatha kukwaniritsa zofunikira za liwiro lalikulu, chitetezo ndi kukana kwamphamvu kwa ma brake pads.
(4) Lili ndi mphamvu zamakina abwino komanso zinthu zakuthupi. Wokhoza kupirira kukakamizidwa kwakukulu ndi kukameta ubweya. Zopangira zokhutiritsa mumsonkhano musanagwiritse ntchito, pamafunika kubowola, kusonkhana ndi kukonza makina, kuti mupange msonkhano wa brake pad. Choncho, pamafunika kuti zinthu zotsutsana ziyenera kukhala ndi mphamvu zokwanira zamakina kuti zitsimikizire kuti palibe kuwonongeka ndi kugawanika panthawi yokonza kapena kugwiritsa ntchito.
(5) Amakhala ndi kutentha kochepa kwambiri. Kaya ndi m'badwo woyamba wa zida za ceramic za M09 kapena m'badwo wachinayi wa ma brake pads a TD58, zitha kuwonetsetsa kuti galimotoyo ili ndi mabuleki abwino kuti zitsimikizire chitetezo, komanso kutsika kwamafuta kwa ma brake pads ndikochepa kwambiri. .
(6) Sinthani magwiridwe antchito a ma brake pads. Chifukwa cha kutentha kwachangu kwa zida za ceramic, friction coefficient yake ndi yapamwamba kuposa yazitsulo zopumira pakupanga mabuleki.
(7) Chitetezo. Ma brake pads amatulutsa kutentha kwambiri nthawi yomweyo akamakwera mabuleki, makamaka pa liwiro lalikulu kapena mabuleki mwadzidzidzi. Pa kutentha kwambiri, kugunda kwachitsulo kwa pepala la friction kudzachepa, komwe kumatchedwa kuwola kwa kutentha. Kuwola kochepa kwa ma brake pads wamba, kutentha kwambiri komanso kutentha kwamafuta a brake panthawi yoboola mwadzidzidzi kumapangitsa kuti mabuleki achedwe, komanso kutayika kwa mabuleki kutsika kwachitetezo.
(8) Chitonthozo. Muzizindikiro zotonthoza, eni ake nthawi zambiri amakhudzidwa kwambiri ndi phokoso la ma brake pads, kwenikweni, phokoso limakhalanso vuto lomwe ma brake pads wamba sanathe kulithetsa kwa nthawi yayitali. Phokoso limapangidwa ndi kukangana kwachilendo pakati pa mbale yokangana ndi chimbale cha friction, ndipo zifukwa zomwe zimapangidwira zimakhala zovuta kwambiri, mphamvu zowonongeka, kutentha kwa brake disc, liwiro la galimoto ndi nyengo zingakhale chifukwa cha phokoso.
Kuphatikiza apo, zomwe zimayambitsa phokoso m'magawo atatu osiyanasiyana oyambira mabuleki, kukhazikitsa mabuleki ndi kutulutsa mabuleki ndizosiyana. Ngati phokoso lafupipafupi lili pakati pa 0 ndi 550Hz, galimotoyo siimva, koma ngati iposa 800Hz, mwiniwakeyo akhoza kumva phokoso la brake.
(9) Makhalidwe abwino kwambiri azinthu. Ceramic brake pads pogwiritsa ntchito tinthu tating'ono ta graphite / mkuwa / zoumba zapamwamba (zopanda asibesitosi) ndi theka-zitsulo ndi zida zina zamakono zokhala ndi kutentha kwambiri, kukana kuvala, kukhazikika kwa brake, kukonza ma brake disc, kuteteza chilengedwe, popanda phokoso lalitali. moyo utumiki ndi ubwino zina, kuthana ziyangoyango ananyema ziyangoyango pa zinthu ndi ndondomeko zolakwika pakali pano zapamwamba kwambiri padziko lonse ceramic ananyema ziyangoyango. Kuphatikiza apo, mpira wa slag wa ceramic ndiwotsika, kuwongolera ndikwabwino, ndipo kuvala kwapawiri ndi phokoso la ma brake pads zitha kuchepetsedwa.
(10) Moyo wautali wautumiki. Moyo wautumiki ndi chizindikiro chomwe timakhudzidwa kwambiri nacho, moyo wautumiki wa ma brake pads uli pansi pa makilomita 60,000, ndipo moyo wautumiki wa ma brake pads ndi makilomita oposa 100,000. Ndi chifukwa chapadera chilinganizo zakuthupi ntchito ceramic ziyangoyango ananyema ndi 1 kwa 2 mitundu ya ufa electrostatic, ndi zipangizo zina ndi zipangizo sanali electrostatic, kuti ufa adzatengedwa ndi mphepo ndi kayendedwe ka galimoto, ndipo sadzatsatira gudumu zimakhudza kukongola kwa gudumu. Moyo wa zinthu za ceramic ndi woposa 50% kuposa wazitsulo wamba. Mukamagwiritsa ntchito ma brake pads, sipadzakhala kukanda (ndiko kuti, zokanda) pa brake disc, zomwe zimakulitsa moyo wautumiki wa chimbale choyambirira cha brake disc ndi 20%.
