Ma brake pads ndi imodzi mwamagawo ofunikira kwambiri achitetezo pamabuleki agalimoto.Ma brake pads amatenga gawo lalikulu pakuchita mabuleki, motero akuti ma brake pads amateteza anthu ndi magalimoto.
Ng’oma ya mabuleki imakhala ndi nsapato za brake, koma anthu akamatchula ma brake pads, amatchulanso ma brake pads ndi nsapato za brake.
Mawu akuti "disc brake pads" amatanthauza ma brake pads omwe amaikidwa pa mabuleki a disk, osati ma brake disc.
Ma brake pads amakhala ndi zigawo zazikulu zitatu: zitsulo zotsamira (mbale yoyambira), zomatira, ndi chipika chomangira.Gawo lovuta kwambiri ndi friction block, mwachitsanzo, mawonekedwe a friction block.
Mapangidwe a zinthu zokangana nthawi zambiri amakhala ndi mitundu 10-20 yazinthu zopangira.Njirayi imasiyanasiyana kuchokera kuzinthu kupita kuzinthu, ndipo kamangidwe kake kamakhala kotengera luso lachitsanzo.Opanga zinthu za friction amasunga mafomu awo kukhala obisika kwa anthu.
Poyambirira asibesitosi adatsimikizira kuti ndizovala zogwira mtima kwambiri, koma zitadziwika kuti ulusi wa asibesitosi ndi wovulaza thanzi, zida izi zidasinthidwa ndi ulusi wina.Masiku ano, ma brake pads abwino sayenera kukhala ndi asibesitosi, osati zokhazo, ayeneranso kupewa zitsulo zamtengo wapatali, zodula komanso zosatsimikizika zogwira ntchito komanso sulfide momwe angathere.Makampani opanga zinthu zolimbana ndi ntchito yayitali ndikupitiliza kupanga zida zatsopano kuti apititse patsogolo magwiridwe antchito azinthu zokangana, kuteteza chilengedwe komanso chuma.
Friction zakuthupi ndi gulu lazinthu zomwe mapangidwe ake amapangidwa ndi: zomatira: 5-25%;filler: 20-80% (kuphatikiza chosinthira mikangano);Kulimbitsa CHIKWANGWANI: 5-60%
Ntchito ya binder ndi kulumikiza zigawo za zinthu pamodzi.Ili ndi kutentha kwabwino komanso mphamvu.Ubwino wa binder umakhudza kwambiri magwiridwe antchito.Zomangira makamaka zikuphatikizapo
Thermosetting resins: phenolic resins, modified phenolic resins, utomoni wapadera wosamva kutentha.
Mphira: mphira wachilengedwe wopangidwa ndi mphira
Resins ndi rubbers amagwiritsidwa ntchito palimodzi.
Ma friction fillers amapereka ndikukhazikika kwa mikangano ndikuchepetsa kuvala.
Friction filler: barium sulfate, alumina, kaolin, iron oxide, feldspar, wollastonite, ufa wachitsulo, mkuwa (ufa), aluminiyamu ufa…
Kuwongolera magwiridwe antchito: graphite, ufa wokangana, ufa wa rabara, ufa wa coke
Kulimbitsa ulusi kumapereka mphamvu zakuthupi, makamaka kutentha kwambiri.
Ulusi wa asibesitosi
Ulusi wa asibesitosi: ulusi wopangira, ulusi wachilengedwe, ulusi wopanda mchere, ulusi wachitsulo, ulusi wagalasi, ulusi wa kaboni
Mkangano ndi kukana kuyenda pakati pa zinthu ziwiri zomwe zikuyenda.
Mphamvu ya friction (F) imayenderana ndi zomwe zimapangidwa ndi coefficient of friction (μ) ndi kukakamiza kwabwino (N) molunjika pamalo ogundana, omwe amawonetsedwa ndi fomula ya fizikisi: F=μN.Kwa ma brake system, ndiye kugundana pakati pa brake pad ndi brake disc, ndipo N ndi mphamvu yomwe imagwiritsidwa ntchito ndi pistoni ya caliper ku pad.
Kuchuluka kwa coefficient of friction, mphamvu yolimbana kwambiri.Komabe, coefficient of friction pakati pa brake pad ndi disc idzasintha chifukwa cha kutentha kwakukulu komwe kumapangidwa pambuyo pa kukangana, zomwe zikutanthauza kuti coefficient of friction imasintha ndi kusintha kwa kutentha, ndipo pad iliyonse ya brake imakhala ndi coefficient yosiyana ya friction change curve. chifukwa cha zida zosiyanasiyana, zotengera zosiyanasiyana ananyema ndi osiyana mulingo woyenera kutentha kutentha ndi ntchito osiyanasiyana kutentha ntchito.
Chizindikiro chofunikira kwambiri cha ma brake pads ndi coefficient of friction.Mtundu wapadziko lonse wa brake friction coefficient uli pakati pa 0.35 ndi 0.40.Ngati friction coefficient ndi yotsika kuposa 0.35, mabuleki adzadutsa mtunda wotetezeka wa braking kapena kulephera, ngati friction coefficient ndi yoposa 0.40, mabuleki amatha kukhala ndi ngozi zadzidzidzi ndikugwedezeka.
Momwe mungayesere ubwino wa ma brake pads

- Kuyika
- Ma brake pads apamwamba kwambiri: kugundana kwakukulu kokwanira, magwiridwe antchito abwino, komanso kukhazikika pazizindikiro zonse za kutentha, kuthamanga ndi kupanikizika
Za phokoso la brake
Phokoso la brake ndi vuto la braking system ndipo lingakhale logwirizana ndi zigawo zonse za braking system;palibe amene adapeza kuti ndi mbali iti ya braking yomwe imakankhira mpweya kuti apange phokoso la brake.
- Phokoso likhoza kubwera kuchokera ku kukangana kosagwirizana pakati pa ma brake pads ndi ma brake discs ndikupanga kugwedezeka, mafunde a phokoso la kugwedezeka uku amatha kudziwika ndi dalaivala m'galimoto.Phokoso la 0-50Hz lotsika pafupipafupi silimadziwika m'galimoto, madalaivala a 500-1500Hz sangawaone ngati phokoso la brake, koma madalaivala a phokoso la 1500-15000Hz amaziwona ngati phokoso la brake.Zomwe zimayambitsa phokoso la brake ndi kuthamanga kwa brake, kutentha kwa friction pad, kuthamanga kwagalimoto ndi nyengo.
- Kulumikizana kwamphamvu pakati pa ma brake pads ndi ma brake discs ndikulumikizana kwa mfundo, mukamakangana, malo aliwonse okhudzana ndi kukangana sikupitilira, koma kusinthasintha pakati pa mfundo, kusinthasintha uku kumapangitsa kuti mikangano ikhale yotsatizana ndi kugwedezeka kwazing'ono, ngati dongosolo la braking lingathe. bwino kuyamwa kugwedezeka, sikudzachititsa phokoso lanyema;M'malo mwake, ngati dongosolo braking bwino kukulitsa kugwedera, kapena ngakhale resonance, mwina M'malo mwake, ngati dongosolo ananyema amakulitsa kugwedera bwino, kapena ngakhale umatulutsa resonance, izo zingabweretse ananyema phokoso.
- Kuchitika kwa phokoso la brake ndikwachisawawa, ndipo yankho lomwe lilipo pano ndikusinthanso ma brake system kapena kusintha mwadongosolo kapangidwe kazinthu zofunikira, kuphatikiza, komwe, kapangidwe ka ma brake pads.
- Pali mitundu yambiri yaphokoso pa nthawi ya braking, yomwe imatha kusiyanitsa: phokoso limapangidwa panthawi ya braking;phokoso limodzi ndi ndondomeko yonse ya braking;phokoso limapangidwa pamene brake imatulutsidwa.
Santa Brake, monga fakitale yopanga ma brake pad ku China, imatha kupatsa makasitomala zinthu zapamwamba kwambiri zopangira ma brake pad monga semi-metallic, ceramic ndi low zitsulo.
Zogulitsa za Semi-metallic brake pads.
Kuchita kwakukulu
Zapamwamba lalikulu tinthu chiphunzitso
Kuthamanga kwakukulu komanso kokhazikika, kuonetsetsa chitetezo chanu cha brake ngakhale pa liwiro lalikulu kapena mabuleki mwadzidzidzi
Phokoso lochepa
Kuyenda momasuka komanso kuyankha
Low abrasion, woyera ndi wolondola
Fomula yopanda asbestos yopanda chitsulo, yathanzi komanso chitetezo cha chilengedwe

Zogulitsa za Ceramic formula brake pad.
Ubwino woyambirira wa fakitale.Phunzirani njira zapadziko lonse lapansi zopanda zitsulo komanso zitsulo zotsika kuti mukwaniritse zomwe fakitale imafunikira pamtunda wamabuleki
Anti-vibration ndi anti-stirring attachments kuteteza phokoso ndi jitter pamlingo waukulu
Kumanani ndi European ECE R90 standard
Kumverera bwino kwa braking, kumvera, kumakwaniritsa zofunikira zamagalimoto apakati komanso apamwamba kwambiri
Kuyendetsa mabuleki osalala ndi otetezeka ngakhale m'mizinda yodzaza ndi anthu komanso madera amapiri
Pang'ono akupera ndi woyera
