Dab tsi yog brake pad kev sib txhuam khoom
Nres pads kuj hu ua brake pads. Lub luag haujlwm tseem ceeb ntawm cov khoom siv sib txhuam yog rub tawm ntawm qhov chaw ntawm lub nres nres thaum lub tsheb nres kom ua tiav cov nyhuv braking. Yog li ntawd, nws tsim nyog yuav tsum yog qhov tseem ceeb tshaj plaws ntawm cov qauv nres tsheb.
Feem ntau hais lus, cov khoom siv sib txhuam ntawm lub nres nres yog tsim los ntawm 4 qhov chaw, cov khoom siv yooj yim, cov khoom ntim, cov khoom sib tsoo thiab cov fiber ntau. Qhov kev faib ua feem ntawm cov ntaub ntawv no txawv ntawm cov khoom mus rau cov khoom, nyob ntawm daim ntawv thov thiab coefficient ntawm kev sib txhuam. Tsis tas li ntawd, cov ntaub ntawv sib txhuam uas siv nyob rau hauv ntau qib ntawm lub tsheb thiab disc nres ncoo thiab nruas nres ncoo kuj txawv. Rau cov brakes, qhov tseem ceeb tshaj plaws yog kev tsim cov khoom sib txhuam. Qhov kawg braking nyhuv, hnav tsis kam, kub tsis kam thiab lwm yam khoom ntawm lub nres nres yuav nyob ntawm seb tus txheeb ze proportions ntawm cov khoom sib txawv.
Tam sim no, cov ntaub ntawv sib txhuam ntawm kev ua lag luam tuaj yeem muab faib ua plaub hom los ntawm cov ntaub ntawv yooj yim: asbestos, semi-hlau, qis hlau, thiab NAO ceramic formula (uas yog, asbestos-dawb organic hom). Cia peb saib ze dua ntawm cov brakes ntawm cov khoom sib txawv no.
01 Asbestos formula: Nws tau raug txwv vim ib puag ncig.
02 Semi-metal mix material formula: "Semi-metal" mix brake pads mas siv 30-50 feem pua "dub hlau" raws li kev txhawb fiber ntau thiab tseem ceeb sib tov. Lub ntsiab kom zoo dua yog nyob rau hauv nws zoo heev tshav kub dissipation muaj peev xwm, thiab nws thermal decay kev ua tau zoo. Tab sis vim hais tias lub hardness kuj siab, nws yog ib qho yooj yim los tsim suab nrov.
03 Tsawg hlau sib xyaw hom nres pads: "Low hlau" sib tov hom nres nres feem ntau yog siv cov hlau ferrous thiab cov hlau tsis muaj hlau tsis pub dhau 10 feem pua ntawm cov fibers. Lub ntsiab zoo: nruab nrab hardness, zoo braking kev nplij siab, siab braking rhiab heev thiab tsis tshua muaj suab nrov braking.
04 Ceramic formula: NAO/ceramic formula yog txoj kev loj hlob tam sim no hauv kev tshawb fawb thiab kev loj hlob ntawm kev sib txhuam cov khoom siv mis rau cov brakes. Kev tshawb fawb thaum ntxov thiab kev txhim kho ntawm NAO cov mis yog siv los hloov cov khoom siv asbestos ib txwm siv, uas yog siv cov iav fiber ntau, aramid fiber lossis lwm cov fibers (carbon, ceramics, thiab lwm yam) ua cov khoom siv ntxiv.
Qhov zoo ntawm NAO / ceramic mis yog zoo braking kev nplij siab, tsis tshua muaj suab nrov braking, lub neej ntev kev pab cuam, huv si thiab ntau environmentally phooj ywg. Txawm li cas los xij, vim yog cov yam ntxwv ntawm cov khoom siv nws tus kheej, lub zog nres yog qhov tsawg, thiab nws feem ntau yog siv hauv Japanese thiab Korean qauv; qee cov qauv hnyav hnyav xws li European thiab Asmeskas lub tsheb tsis haum rau cov mis mos ceramic.
