Qhov sib xyaw ntawm lub brake ncoo txiav txim siab qhov kev ua haujlwm ntawm lub nres nres
Lub nres nres yog tsim los ntawm peb ntu: steel phaj, nplaum txheej txheej thiab kev sib txhuam thaiv
Kev sib txhuam thaiv feem ntau yog tsim los ntawm cov khoom sib txhuam. Muaj ob peb lossis ntau tshaj li kaum ob cov ntaub ntawv raw hauv ib lub nres nres. Cov khoom sib txhuam uas tau hais niaj hnub no tsuas yog cov khoom tseem ceeb, tseem hu ua aggregate.
Asbestos nres nres
Lub ntsiab tseem ceeb ntawm cov pawm thaum ntxov yog asbestos. Xyoo 1972, Lub Ntiaj Teb Kev Kho Mob Symposium tau lees paub tias asbestos fibers yuav cuam tshuam kev noj qab haus huv. Nyob rau hauv tib lub xyoo, tsoom fwv ntawm ntau lub teb chaws tau txwv cov qauv kev txwv rau asbestos plua plav.
Qhov zoo: tus nqi qis;
Disadvantages: teeb meem rau tib neeg lub cev, qeeb cua sov dissipation;
(Hauv Suav teb, ntau lub tuam txhab tsis raug cai siv asbestos los tsim cov khoom siv nres)
semi hlau nres pads
Rough steel fibers yog siv los ua ib qho tseem ceeb sib tov, thiab muaj qee qhov kev sib nqus
Disadvantages: yooj yim rau xeb, yooj yim los tsim suab nrov, tsis tshua muaj kub yuav ua rau ntau dua hnav thiab tsim kua muag ntawm tus nres disc, thiab ntau dua braking quab yuam;
Qhov zoo: zoo thermal conduction nyhuv, haum rau braking nyob rau hauv high kub;
hlau-tsawg brakes
Cov khoom siv hlau raug txo qis, thiab cov hmoov tooj liab thiab cov ntaub plaub yog siv los ua ib feem
Disadvantage: me ntsis hnav-resistant
Qhov zoo: zoo thermal conduction thiab kub dissipation, tsis tshua muaj suab nrov, zoo xis nyob thaum braking, thiab ruaj khov coefficient kev sib txhuam;
NAO-ceramic brake pads
Asbestos-dawb organic nres cov ntaub ntawv feem ntau yog siv cov iav fiber ntau, polyester fiber ntau los yog lwm yam fibers (carbon, ceramics, thiab lwm yam) raws li cov ntaub ntawv txhawb zog, uas feem ntau hu ua ceramic brake pads.
Nws qhov kev ua tau zoo yog nyob ntawm hom fiber ntau thiab lwm yam sib xyaw ntxiv;
Tus nqi ntawm ceramic brakes yog siab heev. Muaj yeej tsis muaj ntshiab ceramic nres ncoo hauv Suav tom qab muag. Ntshiab ceramic nres ncoo yog siv rau kev sib tw tsheb;
Hmoov metallurgy nres ncoo thiab carbon-carbon nres pads yog tsuas yog siv nyob rau hauv high-ceev tsheb ciav hlau thiab aircraft;
Qhov zoo thiab qhov tsis zoo ntawm cov ntaub ntawv kev sib txhuam yog feem ntau pom nyob rau hauv: kev sib txhuam kev ua haujlwm, kev tiv thaiv kev qaug zog, rhiab heev rau qhov kub thiab txias, siab thiab ceev, tiv thaiv hnav muaj peev xwm thiab suab nrov. Qhov zoo ntawm cov khoom sib txhuam, qhov zoo dua nws cov khoom sib txhuam tuaj yeem tswj tau ntawm qhov sib txawv ntawm qhov kub thiab txias, siab thiab ceev. Hauv lwm lo lus, nws cov khoom yuav tsum tsis txhob hloov pauv ntau ntawm qhov qis lossis siab kub. Qhov zoo dua ntawm cov khoom sib txhuam, qhov tsawg dua yuav muaj kev nres nres tom qab rov ua dua, uas ua rau "nres pedal" zoo. Cov ntaub ntawv zoo dua kuj txo qhov hnav thiab txo suab nrov.
Xaiv ib nkawm khau ntawm kev ua haujlwm siab tuaj yeem ua kom muaj txiaj ntsig ntawm kev sib tsoo hauv qhov chaw sib txawv thiab ua kom muaj kev nyab xeeb ntawm kev tsav tsheb! ! !
