Mabhureki mapedhi ndeimwe yeakanyanya kuchengetedzwa zvikamu zvemota mabhureki system.Mabhureki mapedhi anoita basa rakasimba mukubhureki, saka zvinonzi mabrake pads akanaka anodzivirira vanhu nemota.
Chigubhu chebhureki chine bhutsu dzemabhureki, asi kana vanhu vachidaidza mabhureki pads, vanotaura nezvemabhureki mabhureki nebhutsu dzemabhureki kazhinji.
Izwi rekuti "disc brake pads" rinonyanya kureva mabhureki akaiswa pamabhureki edhisiki, kwete mabhureki disc.
Mabhureki mapedhi ane zvikamu zvitatu zvikuru: simbi inotsigira (backing plate), inonamira, uye friction block.Chikamu chinonyanya kukosha ndeye friction block, kureva formula ye friction block.
Iyo fomula yeiyo friction material inowanzo umbwa 10-20 marudzi ezvigadzirwa.Iyo fomula inosiyana kubva kune chigadzirwa kuenda kune chigadzirwa, uye kuvandudzwa kweformula kunoenderana neiyo chaiyo tekinoroji paramita yemuenzaniso.Vagadziri veFriction zvinhu vanochengeta mafomula avo akavanzika kubva kuruzhinji.
Pakutanga asbestos yakaratidza kuti ndiyo inonyanya kushandiswa kupfeka zvinhu, asi mushure mokunge yazivikanwa kuti asbestos fibers yaikuvadza kuhutano, chinhu ichi chakatsiviwa nemamwe mafiber.Mazuva ano, mabhureki emhando yepamusoro haafaniri kunge ane asbestos, uye kwete izvozvo chete, anofanirwawo kudzivirira simbi yakakwira, inodhura uye isina chokwadi mashandiro efiber uye sulfides zvakanyanya sezvinobvira.Makambani eFriction zvinhu makambani basa renguva refu nderekuenderera mberi nekugadzira zvinhu zvitsva zvekuvandudza mashandiro ezvekukwenya, kuchengetedza kwezvakatipoteredza uye hupfumi.
Friction material chinhu chakaumbwa chine kuumbwa kwechimiro chekutanga: adhesive: 5-25%;filler: 20-80% (kusanganisira friction modifier);kusimbisa fiber: 5-60%
Basa rebhainda nderekubatanidza zvikamu zvezvinhu pamwechete.Iine kunaka kwekushisa kwekudzivirira uye simba.Hunhu hwebinder hune simba guru pakushanda kwechigadzirwa.Binders kunyanya zvinosanganisira
thermosetting resins: phenolic resins, modified phenolic resins, yakakosha-inodzivirira kupisa resins.
Rubber: natural rubber synthetic rubber
Resins uye rubbers zvinoshandiswa pamwe chete.
Friction fillers inopa uye inodzikamisa friction zvivakwa uye kuderedza kupera.
Friction filler: barium sulfate, alumina, kaolin, iron oxide, feldspar, wollastonite, iron poda, mhangura (hupfu), aluminium poda…
Friction performance modifier: graphite, friction poda, rabha poda, coke poda
Kusimbisa fiber kunopa simba rezvinhu, kunyanya mumamiriro ekupisa.
Asbestos fibers
Mafiibha asiri-asbestos: mafibhi ekugadzira, shinda dzechisikigo, shinda dzisiri dzemaminerari, simbi dzesimbi, girazi fibers, kabhoni fibers.
Fruction (Friction) kureva kuramba kufamba pakati pezviso zviviri zvinenge zviri kufamba.
Simba rekukwesha (F) rinoenderana nechigadzirwa cheiyo coefficient ye friction (μ) uye kudzvanywa kwakanaka (N) munzira yakatwasuka pamhepo inokwesha, inoburitswa nefizikisi formula: F = μN.Kune iyo brake system, ndiyo coefficient yekupokana pakati pebrake pad uye brake disc, uye N ndiyo simba rinoshandiswa necaliper piston kune padhi.
Iyo yakakura coefficient of friction, iyo yakakura simba rekukwesha.Nekudaro, iyo coefficient of friction pakati pe brake pad ne disc ichachinja nekuda kwekupisa kwakanyanya kunoitwa mushure mekukwesha, zvinoreva kuti coefficient of friction inoshanduka nekuchinja kwekushisa, uye imwe neimwe brake pad ine akasiyana coefficient of friction change curve. nekuda kwezvinhu zvakasiyana, saka akasiyana mabhureki mapedhi ane akasiyana optimal tembiricha yekushanda uye inoshanda tembiricha yekushanda.
Iyo inonyanya kukosha yekuita chiratidzo chebrake pads ndiyo coefficient yefriction.Iyo yenyika standard brake friction coefficient iri pakati pe0.35 ne0.40.Kana iyo friction coefficient yakadzikira pane 0.35, mabhureki anodarika yakachengeteka mabhureki chinhambwe kana kutotadza, kana iyo friction coefficient yakakwira kupfuura 0.40, mabhureki anozongoita tsaona yekukamhina uye rollover tsaona.
Maitiro ekuyera kunaka kwemabrake pads
Safety
- Yakagadzikana Friction Coefficient
(Yakajairwa tembiricha braking simba, kupisa kunyatsoshanda
Wading kunyatsoita, kumhanya kwakanyanya kuita)
- Kudzoreredza kuita
Kupokana nekukuvara nekuora
Nyaradzo
- Pedal kunzwa
-Mutsindo wakaderera / kuzununguka kwakaderera
- Kuchena
Kurarama kwenguva refu
- Low kupfeka mwero
-Kupfeka mwero pakupisa kwakanyanya ambient
Fit
- Mounting saizi
-Friction pamusoro paste uye mamiriro
Zvishandiso uye Chitarisiko
- Kutsemuka, kuputika, delamination
-Alarm waya uye kuvhunduka pads
- Packaging
- Yemhando yepamusoro mabhureki pads: yakakwira zvakakwana coefficient of friction, yakanaka kunyaradza kuita, uye yakagadzikana mune zvese zviratidzo zvekushisa, kumhanya uye kudzvanywa.
Nezve mabhureki noise
Ruzha rwebhureki idambudziko reiyo braking system uye inogona kunge yakabatana kune ese ezvikamu zveiyo braking system;hapana ati awana kuti ndeipi chikamu chebhureki chinosunda mhepo kuita ruzha rwebhureki.
- Ruzha runogona kubva mukukakavadzana kusingaenzaniswi pakati pemabhureki pads uye mabhureki discs uye kuburitsa vibration, mafungu eruzha ekudengenyeka uku anogona kuzivikanwa nemutyairi mumotokari.0-50Hz yakaderera frequency ruzha haionekwe mumotokari, 500-1500Hz ruzha madhiraivha haazvione seruzha rwebhureki, asi 1500-15000Hz yakakwirira frequency ruzha vatyairi vanoiona seruzha rwebhureki.Iwo makuru anotaridza ruzha rwebhureki anosanganisira kudzvanywa kwebhureki, friction pad tembiricha, kumhanya kwemotokari uye mamiriro ekunze.
-Kudhumhana kwekubatana pakati pemabhureki pads uye mabhureki discs ndeyekusangana, mukuita friction, imwe neimwe yekubata nzvimbo yekukwesha haisi kuenderera, asi kuchinjana pakati pemapoinzi, kuchinjika uku kunoita kuti kukwesha kuperekedzwe nediki vibration, kana iyo braking system inogona. inonyatso tora vibration, haizokonzeri ruzha rwebhureki;pane zvinopesana, kana iyo braking system ichanyatso wedzera vibration, kana kunyange resonance, inogona Asi, kana bhureki system ikawedzera vibration zvinobudirira, kana kutoburitsa resonance, inogona kuburitsa ruzha rwebhureki.
- Kuitika kweruzha rwemabhureki hakuna kurongeka, uye mhinduro iripo ndeyekugadzirisa zvakare mabhureki system kana kushandura zvakarongeka chimiro chezvikamu zvakakosha, kusanganisira, hongu, chimiro chemabrake pads.
- Kune akawanda marudzi eruzha panguva yekubhureki, iyo inogona kusiyaniswa ne: ruzha runogadzirwa panguva yekubhureki;ruzha runoperekedzwa nehurongwa hwese hwebhureki;ruzha runogadzirwa kana bhureki raburitswa.
