Ceramic brake pads yog ib hom nres nres uas suav nrog cov ntxhia fiber ntau, aramid fiber ntau thiab ceramic fiber (vim steel fiber ntau tuaj yeem xeb, ua suab nrov thiab plua plav, thiab yog li tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ceramic hom formulations).
Ntau tus neeg siv khoom yuav pib ua yuam kev ceramic li ua los ntawm ceramics, tab sis qhov tseeb, ceramic nres pads yog tsim los ntawm lub hauv paus ntsiab lus ntawm cov hlau ceramics es tsis yog hlau ceramics.Nyob rau ntawm qhov kub siab no, qhov chaw ntawm lub nres nres yuav raug sintered hlau-ceramic cov tshuaj tiv thaiv zoo sib xws, kom lub brake ncoo muaj kev ruaj ntseg zoo ntawm qhov kub thiab txias.Cov tsoos nres nres tsis tsim sintering tshwm sim ntawm qhov kub thiab txias, thiab qhov kub ntawm qhov saum npoo tuaj yeem ua rau cov khoom ntog los yog ua rau lub cushion ntawm huab cua, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm kev ua haujlwm nres tom qab nres nres lossis tag nrho poob. ntawm braking.
Ceramic brake pads muaj qhov zoo hauv qab no dua li lwm hom nres nres.
(1) Qhov sib txawv loj tshaj plaws ntawm ceramic nres ncoo thiab tsoos nres nres yog qhov tsis muaj hlau.Hauv cov tsoos nres nres, hlau yog cov khoom tseem ceeb uas ua rau muaj kev sib txhuam, uas muaj lub zog siab braking, tab sis nws nyiam hnav thiab suab nrov.Thaum cov pads ceramic tau teeb tsa, yuav tsis muaj kev sib cav sib txawv (piv txwv li lub suab nrov) thaum tsav tsheb.Vim hais tias ceramic nres ncoo tsis muaj cov khoom siv hlau, lub suab nrov ntawm cov tsoos hlau nres cov ntaub qhwv ib leeg (piv txwv li nres nres thiab nres discs) raug zam.
(2) Kev sib txhuam coefficient.Kev sib txhuam coefficient yog qhov tseem ceeb tshaj plaws ntawm kev ua tau zoo ntawm cov khoom siv sib txhuam, uas muaj feem cuam tshuam rau qhov zoo lossis qhov tsis zoo ntawm lub braking muaj peev xwm ntawm tus nres nres.Nyob rau hauv lub braking txheej txheem vim lub tshav kub generated los ntawm kev sib txhuam, kev ua hauj lwm kub nce, cov kev sib txhuam cov khoom siv ntawm lub nres nres los ntawm qhov kub thiab txias, coefficient ntawm kev sib txhuam pib poob.Hauv kev siv tiag tiag, nws yuav txo qhov kev sib txhuam quab yuam, yog li txo cov nyhuv braking.Cov khoom sib txhuam ntawm cov pawm tsis zoo no tsis paub tab, thiab kev sib txhuam coefficient siab dhau ua rau tsis muaj kev nyab xeeb xws li poob ntawm kev taw qhia thaum lub sij hawm braking, hlawv pads thiab khawb discs.Txawm hais tias qhov kub ntawm lub nres nres yog siab li 650 degrees, kev sib txhuam coefficient ntawm ceramic nres ncoo tseem nyob ib ncig ntawm 0.45-0.55, uas tuaj yeem ua kom lub tsheb muaj kev ua haujlwm zoo.
(3) Ceramic muaj thermal stability zoo dua thiab qis thermal conductivity, thiab zoo hnav tsis kam.Kev siv lub sijhawm ntev kub hauv 1000 degrees, tus yam ntxwv no ua rau ceramic tuaj yeem tsim nyog rau ntau yam khoom siv ua haujlwm siab, kev ua haujlwm siab, tuaj yeem ua tau raws li tus brake ncoo high-speed, kev nyab xeeb, hnav tsis kam thiab lwm yam kev cai.
(4) Nws muaj lub zog zoo txhua yam thiab lub cev muaj zog.Muaj peev xwm tiv taus siab loj thiab shear quab yuam.Kev sib txhuam cov khoom siv hauv kev sib dhos ua ntej siv, yuav tsum muaj kev sib dhos, sib dhos thiab lwm yam kev ua haujlwm, thiaj li ua kom lub brake pad sib dhos.Yog li ntawd, cov khoom siv sib txhuam yuav tsum muaj lub zog siv hluav taws xob txaus los xyuas kom meej tias kev ua haujlwm lossis kev siv cov txheej txheem tsis tshwm sim tawg thiab tawg.
(5) Muaj cov khoom siv hluav taws xob tsawg heev.
(6) Txhim khu kev ua haujlwm ntawm cov pawm nres.Vim tias cov khoom siv hluav taws xob sai sai ntawm cov khoom siv ceramic, nws yog siv los tsim cov brakes, thiab nws cov coefficient ntawm kev sib txhuam yog siab dua li ntawm cov hlau nres.
(7) Kev nyab xeeb.Nres pads ua kom kub kub sai sai thaum nres, tshwj xeeb tshaj yog thaum muaj kev kub ceev lossis thaum muaj xwm txheej ceev.Nyob rau hauv lub xeev kub, qhov sib txhuam coefficient ntawm kev sib txhuam cov ntaub qhwv yuav poob, hu ua thermal recession.Ordinary brake pads thermal degradation ntawm qis, kub siab thiab thaum muaj xwm ceev braking thaum lub nres dej kub nce kom lub nres nres nres, los yog txawm tias qhov poob ntawm braking nyhuv kev nyab xeeb yog tsawg.
(8) kev nplij siab.Ntawm qhov ntsuas kev nplij siab, cov tswv tsev feem ntau txhawj xeeb txog lub suab nrov ntawm lub nres nres, qhov tseeb, lub suab nrov kuj yog qhov teeb meem ntev uas tsis tuaj yeem daws tau los ntawm cov nres nres zoo li qub.Lub suab nrov yog tsim los ntawm qhov txawv txav ntawm kev sib txhuam ntawm qhov sib txhuam thiab cov kev sib txhuam disc, thiab cov laj thawj ntawm nws cov tiam muaj kev nyuaj heev, xws li lub zog ntawm lub braking, qhov kub thiab txias ntawm lub brake disc, qhov ceev ntawm lub tsheb thiab cov huab cua yog. txhua yam ua tau rau lub suab nrov.
(9) Cov khoom zoo heev.Ceramic brake pads siv cov khoom loj ntawm graphite / tooj dag / advanced ceramic (non-asbestos) thiab semi-hlau thiab lwm yam khoom siv high-tech nrog kub tsis kam, hnav tsis kam, nres ruaj khov, kho kev raug mob nres disc, kev tiv thaiv ib puag ncig, tsis muaj suab nrov ntev. kev pab cuam lub neej thiab lwm yam zoo, kom kov yeej cov tsoos brake ncoo cov khoom thiab cov txheej txheem tsis xws luag yog cov sophisticated thoob ntiaj teb advanced ceramic nres pads.Tsis tas li ntawd, cov ntsiab lus qis ntawm ceramic slag pob thiab kev txhim kho zoo kuj tuaj yeem txo tus khub hnav thiab lub suab nrov ntawm cov pawm nres.
(10) Lub neej ua haujlwm ntev.Kev pabcuam lub neej yog qhov qhia txog kev txhawj xeeb loj.Lub neej kev pab cuam ntawm cov pawm zoo tib yam yog qis dua 60,000 km, thaum lub neej kev pab cuam ntawm cov pawm ceramic yog siab dua 100,000 km.Tias yog vim li cas cov khoom siv hluav taws xob siv lub cim tshwj xeeb ntawm tsuas yog 1 mus rau 2 hom electrostatic hmoov, lwm cov ntaub ntawv yog cov khoom siv tsis zoo, yog li cov hmoov yuav raug tshem tawm los ntawm cua nrog lub zog ntawm lub tsheb, thiab yuav tsis lo. mus rau lub log hub kom cuam tshuam rau kev zoo nkauj.Lub neej ntev ntawm cov ntaub ntawv ceramic yog ntau dua 50% siab dua li cov khoom siv hlau zoo tib yam.Tom qab siv cov ntaub thaiv npog ceramic, yuav tsis muaj qhov khawb (piv txwv li khawb) ntawm cov nres discs, ncua kev pab cuam lub neej ntawm cov qub discs los ntawm 20%.
