Txhua lub tsheb yuav tsum tau nruab nrog lub braking system, cov actuators uas yog nres nres nyob rau hauv kev sib cuag nrog lub nres nruas los yog disc.Qhov tseem ceeb ntawm cov ntaub qhwv yog kev sib txhuam hauv ob sab phlu.Nyeem tag nrho txog cov khoom no, lawv hom, tsim thiab xaiv txoj cai hauv kab lus.
Dab tsi yog brake pad lining?
Lub brake ncoo hauv ob sab phlu (kev sib txhuam hauv ob sab phlu) yog ib feem ntawm cov actuators ntawm lub brakes ntawm lub tsheb, uas ua kom cov creation ntawm braking torque vim muaj kev sib txhuam quab yuam.
Kev sib txhuam hauv ob sab phlu yog qhov tseem ceeb ntawm lub nres nres, nws yog nyob rau hauv kev sib cuag ncaj qha nrog lub nruas nres lossis disc thaum nres tsheb.Vim muaj kev sib txhuam quab yuam tshwm sim los ntawm kev sib cuag nrog lub nruas / disc, lub hauv ob sab phlu absorbs lub kinetic zog ntawm lub tsheb, hloov mus rau hauv tshav kub thiab muab ib tug txo nyob rau hauv ceev los yog ib tug tag nrho nres.Cov hauv ob sab phlu muaj qhov sib ntxiv ntawm kev sib txhuam nrog cam khwb cia hlau thiab hlau (los ntawm cov nruas nres thiab discs), thiab tib lub sijhawm muaj kev tiv thaiv siab hnav thiab tiv thaiv kev hnav ntawm lub nruas / disc.
Niaj hnub no, muaj ntau yam ntawm cov brakes hauv ob sab phlu, thiab rau kev xaiv kom raug ntawm cov khoom no, nws yog ib qho tsim nyog yuav tsum nkag siab txog lawv cov kev faib tawm thiab kev tsim.
Hom thiab tsim ntawm brake pad linings
Kev sib txhuam ntawm cov ntaub thaiv npog tuaj yeem muab faib ua pawg raws li lub hom phiaj, tsim thiab teeb tsa, nrog rau cov muaj pes tsawg leeg los ntawm lawv tsim.
Raws li lub hom phiaj, cov ntaub qhwv tau muab faib ua ob hom:
• Rau lub nruas nres;
• Rau disc nres.
Lub nruas nres pads yog ib lub phaj arcuate nrog ib lub vojvoog sab nraud coj mus rau sab hauv ntawm lub nruas.Thaum braking, cov ntaub so ntswg tawm tsam sab hauv ntawm lub nruas, txo qhov ceev ntawm lub tsheb.Raws li txoj cai, nruas nres kev sib txhuam hauv ob sab phlu muaj qhov chaw ua haujlwm loj.Txhua lub log nres mechanism yog nruab nrog ob txoj hlua nyob rau sab nraud, uas ua kom muaj kev sib faib ntawm lub zog.
Disc nres hauv ob sab phlu yog cov pav ca ntawm crescent lossis lwm yam duab uas muab qhov chaw siab tshaj plaws nrog lub nres nres.Txhua lub log nres siv ob lub ncoo, nruab nrab ntawm lub disc yog clamped thaum braking.
Tsis tas li ntawd, cov hlua nres nres tau muab faib ua ob pawg raws li qhov chaw ntawm kev teeb tsa:
• Rau lub log nres - pem hauv ntej, nram qab thiab universal;
• Rau qhov chaw nres tsheb nres ntawm cov tsheb thauj khoom (nrog lub nruas ntawm lub kiv cua).
Raws li txoj cai, kev sib txhuam hauv ob sab phlu yog cov phaj molded los ntawm cov khoom siv polymer nrog cov khoom sib xyaw.Cov khoom muaj xws li ntau yam khoom - thav duab-forming, filling, heat dissipating, binders thiab lwm yam.Nyob rau tib lub sijhawm, tag nrho cov khoom siv los ntawm cov ntaub qhwv tuaj yeem muab faib ua ob pawg loj:
• Asbestos;
• Tsis muaj asbestos.
Lub hauv paus ntawm asbestos linings yog, raws li nws yog ib qho yooj yim to taub, asbestos fibers (hnub no nws yog ib tug kuj muaj kev ruaj ntseg chrysotile asbestos), uas ua raws li ib tug phaj ncej uas tuav tag nrho cov khoom.Cov ntaub ntawv zoo li no yog mos, tab sis tib lub sij hawm muaj kev sib txhuam coefficient siab, lawv tiv thaiv kev hnav ntawm lub nruas / disc ntau dhau thiab muaj suab nrov txo.Nyob rau hauv cov khoom tsis muaj asbestos, ntau yam polymer lossis cov ntxhia fibers ua lub luag haujlwm ntawm cov thav duab ntawm qhov muaj pes tsawg leeg, xws li overlays ua raws li ib puag ncig cov qauv, tab sis kim dua thiab qee qhov muaj cov yam ntxwv ua haujlwm tsis zoo (lawv nruj dua, feem ntau nrov, thiab lwm yam. .).Yog li niaj hnub no, asbestos kev sib txhuam hauv ob sab phlu tseem siv dav.
Ntau yam khoom siv polymeric yog siv los ua cov khoom siv hauv kev tsim cov khoom sib tshooj, polymers, resins, rubbers, thiab lwm yam. Tsis tas li ntawd, ceramics, hlau shavings (ua los ntawm tooj liab los yog lwm yam hlau mos) kom zoo dua tshav kub dissipation, thiab lwm yam tej zaum yuav muaj nyob rau hauv cov muaj pes tsawg leeg. .Yuav luag txhua tus neeg tsim khoom siv nws tus kheej (qee zaum tshwj xeeb) cov zaub mov txawv, yog li qhov sib xyaw ntawm cov ntaub ntawv sib txawv tuaj yeem sib txawv.
Friction linings yog tsim los ntawm ob lub ntsiab technologies:
• Txias nias;
• Kub nias.
Nyob rau hauv thawj rooj plaub, linings yog tsim los ntawm cov tiav lawm sib tov nyob rau hauv tshwj xeeb pwm yam tsis muaj cua sov ntxiv.Txawm li cas los xij, ntau lub tuam txhab tseem siv cov khoom siv hluav taws xob tom qab molding.Nyob rau hauv rooj plaub thib ob, qhov sib tov yog nias rau hauv rhuab (hluav taws xob) pwm.Raws li txoj cai, nrog rau kev nias txias, pheej yig dua, tab sis tsis tshua muaj cov hlua ruaj khov tau txais, nrog rau kev kub kub, cov khoom lag luam zoo dua, tab sis kuj kim dua.
Tsis hais txog ntawm txoj kev tsim khoom thiab muaj pes tsawg leeg, tom qab kev tsim khoom, cov hauv ob sab phlu yog polished thiab raug rau lwm yam kev ua haujlwm ntxiv.Friction linings mus muag nyob rau hauv ntau yam configurations:
• Overlays yam tsis muaj qhov mounting thiab fasteners;
• Overlays nrog drilled mounting qhov;
• Overlays nrog qhov thiab ib txheej ntawm fasteners;
• Ua kom tiav cov pawm nres - cov hlua khi rau ntawm lub hauv paus.
Kev sib txhuam ntawm cov ntaub thaiv npog tsis muaj qhov yog qhov chaw thoob ntiaj teb uas tuaj yeem hloov kho rau lub nres nres ntawm ntau lub tsheb, uas muaj qhov tsim nyog qhov ntev thiab lub vojvoog.Overlays nrog lub qhov yog tsim nyog rau qee lub tsheb qauv, nws tuaj yeem nruab rau ntawm cov ntaub qhwv nrog kev sib txawv ntawm qhov tsuas yog tom qab ntxiv qhov drilling, lossis nws tsis tuaj yeem ua tiav.Overlays ua tiav nrog cov fasteners pab txhawb txoj kev teeb tsa thiab pab ua kom cov txiaj ntsig zoo tshaj plaws.
Ua kom tiav cov pawm nres yog ib qho kev sib cais ntawm cov khoom seem, lawv tau siv los kho cov disc brakes, nruas mechanisms nrog cov ntaub qhwv rau cov ntaub qhwv, lossis cov nruas tsis zoo.Ntawm cov tsheb thauj khoom, cov khoom siv no tsis tshua siv.
Kev sib txhuam hauv ob sab phlu yog ntsia rau ntawm lub nres nres nrog rivets (khoom thiab hollow) los yog cov kua nplaum.Rivets yog siv nyob rau hauv nruas nres, kua nplaum feem ntau yog siv nyob rau hauv disc nres pads.Kev siv cov rivets muab lub peev xwm los hloov cov ntaub ntawv thaum lawv hnav.Txhawm rau tiv thaiv kev puas tsuaj rau lub nruas nres lossis disc, rivets yog ua los ntawm cov hlau mos - aluminium thiab nws cov alloys, tooj liab, tooj dag.
Cov khoom siv hluav taws xob thiab hluav taws xob hnav tuaj yeem ntsia tau rau ntawm cov ntaub thaiv npog niaj hnub.Mechanical sensor yog ib lub phaj nyob rau hauv lub cev ntawm lub hauv ob sab phlu, uas, thaum lub sij hawm ib feem ntawm lub cev tawm, pib rub tawm ntawm lub nruas los yog disc, ua ib tug yam ntxwv suab.Lub tshuab hluav taws xob kuj tseem muab zais rau hauv lub cev ntawm lub hauv ob sab phlu, thaum nws hnav, lub voj voog raug kaw (los ntawm lub disk lossis nruas) thiab cov teeb pom kev zoo sib xws ntawm lub dashboard.
Kev xaiv kom raug, hloov thiab ua haujlwm ntawm cov ntaub thaiv npog
Kev sib txhuam hauv ob sab phlu yog raug hnav thaum lub sijhawm ua haujlwm, lawv cov thickness maj mam txo qis, uas ua rau txo qis kev ntseeg siab ntawm cov brakes.Raws li txoj cai, ib txheej ua haujlwm 15-30 txhiab kilometers, tom qab ntawd nws yuav tsum tau hloov.Hauv kev ua haujlwm nyuaj (ntau dua plua plav, txav ntawm cov dej thiab av, thaum ua haujlwm hauv cov khoom hnyav), kev hloov cov ntaub yuav tsum tau ua ntau zaus.Cov hauv ob sab phlu yuav tsum tau hloov thaum lawv hnav mus rau qhov tsawg kawg nkaus pub thickness - feem ntau yog tsawg kawg yog 2-3 hli.
Rau kev hloov pauv, nws yog ib qho tsim nyog yuav tsum siv cov ntaub ntawv sib txhuam uas muaj qhov ntev haum rau lub tsheb tshwj xeeb - qhov dav, qhov ntev thiab tuab (tag nrho qhov tsim nyog tsis yog feem ntau qhia rau hauv ob sab phlu).Tsuas yog nyob rau hauv cov ntaub ntawv no, lub hauv ob sab phlu yuav tag nrho nias rau lub nruas los yog disc thiab txaus braking quab yuam yuav raug tsim.Rau mounting lub ncoo ntawm lub thaiv, koj tuaj yeem siv tsuas yog rivets ua los ntawm cov hlau mos, nws yog qhov zoo dua los muab kev nyiam rau fasteners hauv cov khoom siv.Cov rivets yuav tsum tau muab faus rau hauv lub cev ntawm cov ntaub hauv ob sab phlu kom tiv thaiv lawv los ntawm rub tawm ntawm lub nruas, txwv tsis pub cov khoom yuav raug mob hnyav thiab tsim kua muag thiab yuav ua tsis tiav.
Nws yog ib qho tsim nyog yuav tsum tau hloov cov ntaub ntawv ntawm lub nres nres hauv kev ua tiav, lossis, nyob rau hauv qhov xwm txheej hnyav, ob qho tib si ntawm tib lub log - qhov no yog tib txoj hauv kev los xyuas kom meej qhov kev ua haujlwm ntawm lub tshuab nres.Nws yog ib qho tsim nyog yuav tsum tau ua kom tiav qhov kev hloov pauv raws li cov lus qhia rau kev kho thiab kev saib xyuas ntawm ib lub tsheb tshwj xeeb, txwv tsis pub muaj qhov tshwm sim siab ntawm kev puas tsuaj ntawm cov brakes.
Thaum ua haujlwm ntawm lub tsheb, koj yuav tsum tsis txhob overheating ntawm cov ntaub hauv ob sab phlu, nrog rau lawv cov ntub dej thiab cov kab mob sib kis - tag nrho cov no txo lawv cov peev txheej thiab ua rau muaj feem cuam tshuam.Thaum tsav tsheb los ntawm dej, cov linings yuav tsum tau qhuav (nruab ob peb zaug thiab nias lub nres pedal), nrog rau qhov ntev qhovntsej thiaj tsis mob, nws raug nquahu kom siv lub cav braking, thiab lwm yam. Nrog rau kev ua haujlwm kom raug thiab hloov cov ntaub ntawv raws sijhawm, lub tsheb nres. yuav ua haujlwm ruaj khov thiab nyab xeeb.
