Motokari yega yega ichave ine braking system, ma actuators ayo ari mabrake pads akabatana nedhiramu remabhureki kana disc.Chikamu chikuru chemapadhi ndeye friction linings.Verenga zvese nezvezvikamu izvi, marudzi azvo, dhizaini uye sarudzo yakanaka mune chinyorwa.
Chii chinonzi brake pad lining?
Iyo brake pad lining (friction lining) chikamu chezvinobatisa zvemabhureki emotokari, iyo inovimbisa kusikwa kwebhureki torque nekuda kwekupokana kwemasimba.
Iyo friction lining ndicho chikamu chikuru chebhureki pad, iri kutarisana zvakananga nedhiramu remabhureki kana dhisiki kana uchibhureki mota.Nekuda kwesimba rekupokana rinobva mukusangana nedhiramu / dhisiki, iyo lining inotora kinetic simba remotokari, ichiishandura kuita kupisa uye kupa kudzikira kwekumhanya kana kumira kwakazara.Iyo linings ine yakawedzera coefficient yekupokana nesimbi yakakandwa uye simbi (kubva kune iyo mabhureki madhiramu uye madhisiki anogadzirwa), uye panguva imwechete ane yakakwirira kuramba kupfeka uye kudzivirira kunyanyisa kupfeka kwedhiramu / disc.
Nhasi, kune dzakasiyana siyana dzemabhureki pad linings, uye nekuda kwesarudzo chaiyo yezvikamu izvi, zvinodikanwa kuti unzwisise kurongeka kwavo uye dhizaini.
Mhando uye dhizaini yebrake pad linings
Friction linings yebrake pads inogona kukamurwa kuita mapoka zvichienderana nechinangwa, dhizaini uye kumisikidzwa, pamwe nekuumbwa kwavanoitwa.
Zvinoenderana nechinangwa, mapads akakamurwa kuva marudzi maviri:
• Zvemabhureki engoma;
• Nezve disc mabhureki.
Drum brake pads iplate ye arcuate ine radius yekunze inoenderana nemukati medhiramu.Kana mabhureki, maramba anozorora akatarisana nemukati medhiramu, achidzikisa kumhanya kwemotokari.Sezvo mutemo, dhiramu brake friction linings ine nzvimbo yakakura yekushanda.Imwe neimwe vhiri brake mechanism ine maviri linings ari pakatarisana, ayo anovimbisa kugovaniswa kwemasimba.
Disc brake linings mahwendefa akatsetseka ekrescent kana mamwe maumbirwo anopa iyo yakanyanya kusangana nzvimbo ine brake disc.Imwe neimwe vhiri brake michina inoshandisa maviri mapadhi, pakati peiyo disc inosungirirwa panguva yekubhureki.
Zvakare, brake pad linings yakakamurwa kuita mapoka maviri zvichienderana nenzvimbo yekuisa:
• Kune mabhureki evhiri - pamberi, kumashure uye pasi rose;
• Pamabhureki ekupaka mabhureki emarori (ane dhiramu pane propeller shaft).
Zvimiro, friction linings mahwendefa akaumbwa kubva kumhando dzepolymer ane yakaoma kuumbwa.Kuumbwa kunosanganisira zvikamu zvakasiyana-siyana - furemu-kuumba, kuzadza, kupisa kupisa, binders nezvimwe.Panguva imwecheteyo, zvinhu zvese zvinogadzirwa kubva kune linings zvinogona kukamurwa kuita mapoka maviri makuru:
•Asbestos;
• Asbestos-isina.
Nheyo yeasbestos linings ndeye, sezvazviri nyore kunzwisisa, asbestos fibers (nhasi inenge yakachengeteka chrysotile asbestos), iyo inoshanda seplate frame inobata zvimwe zvikamu.Mapadhi akadaro akapfava, asi panguva imwechete ane yakakwira coefficient yekupokana, anodzivirira kupfeka zvakanyanya kwedhiramu / dhisiki uye vane ruzha rwakaderedzwa.Muzvigadzirwa zvisina asbestos, akasiyana mapolymer kana mineral fibers anoita basa rechimiro chechimiro, zvakafukidzwa zvakadaro zvinoenderana nemaitiro ezvakatipoteredza, asi zvinodhura uye mune dzimwe nguva zvine maitiro akashata (akanyanya kuomarara, anowanzo kuita ruzha, nezvimwe, nezvimwe, .).Naizvozvo, nhasi asbestos friction linings achiri kushandiswa zvakanyanya.
Zvinhu zvakasiyana-siyana zvepolymeric zvinoshandiswa semafirita mukugadzira zvakavharika, mapolymer, resin, rubber, etc. Uyezve, ceramics, simbi shavings (yakagadzirwa nemhangura kana imwe simbi yakapfava) yekubvisa kupisa kuri nani, uye zvimwe zvikamu zvinogona kunge zviripo mukuumbwa. .Anenge ese anogadzira anoshandisa ayo (dzimwe nguva akasiyana) mabikirwo, saka kuumbwa kwe friction linings kunogona kusiyanisa zvakanyanya.
Friction linings inogadzirwa uchishandisa maviri makuru matekinoroji:
• Kutsikirira kunotonhora;
• Kudzvanya kunopisa.
Muchiitiko chekutanga, linings inoumbwa kubva musanganiswa wakapedzwa mumhando dzakakosha pasina kuwedzera kupisa.Nekudaro, vagadziri vazhinji vanowedzera kushandisa kupisa kurapwa kwezvigadzirwa mushure mekuumbwa.Muchiitiko chechipiri, musanganiswa unomanikidzwa mukupisa (magetsi) molds.Sezvo mutemo, nekutsikirira kunotonhora, zvakachipa, asi zvisingasviki linings zvinowanikwa, nekupisa kupisa, zvigadzirwa zvemhando yepamusoro, asiwo zvinodhura.
Pasinei neiyo nzira yekugadzira uye kuumbwa, mushure mekugadzira, iyo linings inokwenenzverwa uye inoiswa kune mamwe ekuwedzera kugadzirisa.Friction linings inoenderera kutengeswa mune akasiyana masisitimu:
• Kufukidzira pasina maburi ekukwira uye fasteners;
• Kufukidzwa nemakomba anosungirirwa;
• Kufukidzira nemakomba uye seti yezvisungo;
• Complete brake pads - linings akaiswa pachigadziko.
Friction linings yemabhureki pads asina maburi zvikamu zvepasi rose zvinogona kugadziridzwa kune mabhureki mapedhi emota dzakasiyana siyana, dzine zviyero zvakakodzera uye radius.Kufukidzira nemakomba kwakakodzera kune mamwe mamodheru emota, zvinokwanisika kuaisa pamapadhi ane akasiyana marongero emakomba chete mushure mekuwedzera kudhirowa, kana hazvigoneke zvachose.Kufukidzira kuzere nemafasteners kunofambisa maitiro ekuisa uye kubatsira kuve nechokwadi chemhando yepamusoro mhedzisiro.
Complete brake pads atove akaparadzana mhando yezvisara, anoshandiswa mukugadzirisa dhisiki mabhureki, madhiramu madhiramu ane mapedhi anonamirwa kumapedhi, kana yakasakara madhiramu madhiramu.Pamarori, zvinhu zvakadaro hazviwanzoshandiswa.
Friction linings akaiswa pamabhureki pads ane rivets (yakasimba uye isina hollow) kana pane glue.Rivets anoshandiswa mumadhiramu mabhureki, glue inonyanya kushandiswa mumadhisiki mabhureki pads.Iko kushandiswa kwerivets kunopa kugona kutsiva linings sezvavanosakara.Kuti udzivise kukuvadzwa kwedhiramu yebhureki kana disc, rivets inogadzirwa nesimbi dzakapfava - aluminium uye alloys ayo, mhangura, ndarira.
Mechanical uye electronic wear sensors inogona kuiswa pane yemazuva ano brake pad linings.A mechanical sensor iplate iri mumuviri we lining, iyo, kana chikamu chacho chapera, chinotanga kukwesha pamusoro pedhiramu kana dhisiki, zvichiita ruzha rwechimiro.Iyo sensor yemagetsi yakavanzwawo mumuviri weiyo lining, kana yakapfekwa, dunhu rakavharwa (kuburikidza nedhisiki kana dhiramu) uye chiratidzo chinoenderana chinovhenekera pane dashboard.
Sarudzo chaiyo, kutsiva uye kushanda kwebrake pad linings
Friction linings inotarisirwa kupfeka panguva yekushanda, ukobvu hwavo hunoderera zvishoma nezvishoma, izvo zvinotungamirira kuderera kwekuvimbika kwemabhureki.Sezvo mutemo, rimwe lining rinoshumira 15-30 zviuru zvemakiromita, mushure mokunge rinofanira kutsiviwa.Mumamiriro ezvinhu akaoma ekushanda (kuwedzerwa guruva, kufamba pamvura uye tsvina, kana uchishanda pasi pemitoro yakakwirira), kuchinjwa kwezvipfeko kunofanira kuitwa kakawanda.Iyo linings inofanira kuchinjwa kana yakapfekwa kusvika kudiki inotenderwa ukobvu - kazhinji inenge 2-3 mm.
Kuti utsive, zvinodikanwa kushandisa friction linings ine zviyero zvakakodzera kune imwe mota - hupamhi, kureba uye ukobvu (ese maparameter anodiwa anowanzo kuratidzwa pane linings).Chete mune iyi kesi, iyo lining ichave yakanyatso kudzvanywa kurwisa chigubhu kana disc uye yakakwana braking simba ichagadzirwa.Pakukwirisa padhi pa block, unogona kushandisa chete rivets akagadzirwa nesimbi dzakapfava, zviri nani kupa zvakafarirwa kune fasteners mukiti.Ma rivets anofanirwa kuvigwa mumuviri wemaraini kuti asakweshera pachigubhu, zvikasadaro zvikamu zvacho zvichabva zvanyanya kubvaruka uye zvinogona kukundikana.
Izvo zvinodikanwa kuti uchinje linings pamabhureki mapedhi mumaseti akazara, kana, muzviitiko zvakanyanyisa, ese ari pavhiri rimwechete - iyi ndiyo chete nzira yekuve nechokwadi chekushanda kwakajairika kwemabhureki masisitimu.Izvo zvinodikanwa kuita kutsiva kwakazara maererano nemirayiridzo yekugadzirisa nekuchengetedza imwe mota, kana zvisina kudaro pane mukana wakakura wekuparara kwemabhureki.
Paunenge uchishanda nemotokari, iwe unofanirwa kudzivirira kupisa kwemarambi, pamwe nekunyorova uye kusvibiswa kwavo - zvese izvi zvinoderedza hupfumi hwavo uye zvinowedzera mukana wekuputsika.Paunenge uchityaira nemumvura, machira anofanirwa kuomeswa (kumhanyisa kakawanda uye wodzvanya brake pedal), nekudzika kwakareba, zvinokurudzirwa kushandisa injini braking, nezvimwewo. Nekushanda kwakakodzera uye nekutsiviwa nenguva kweiyo linings, mabhureki emota. richashanda zvakavimbika uye zvakachengeteka.
