Puas yog ceramic brakes zoo dua hlaunres tsheb?
Nrog rau txoj kev loj hlob ntawm kev siv tshuab tsheb, cov ntaub ntawv ntawm cov ntaub ntawv sib txhuam kuj hloov zuj zus, uas feem ntau muab faib ua ntau pawg:
Hom brake pads
Ua ntej xyoo 1970, lub nres nres muaj ntau cov asbestos, uas yog tus cwj pwm los ntawm kev kub siab, tiv thaiv hluav taws, thiab kev sib txhuam muaj zog. Txawm li cas los xij, vim yog cov hmoov ua los ntawm asbestos hauv cov txheej txheem ntawm kev tsim thiab siv, nws tuaj yeem ua rau ntau yam kev puas tsuaj rau tib neeg lub cev, uas yooj yim ua rau ua pa puas. Cov kab mob tuaj yeem ua rau mob qog noj ntshav, yog li tam sim no asbestos nres nres tau raug txwv thoob ntiaj teb.
Tom qab ntawd tam sim no cov organic nres pads feem ntau kuj hu ua NAO hom nres ncoo (Non-Asbestos Organic, non-asbestos organic brake pads), uas feem ntau muaj 10 feem pua -30 feem pua hlau cov ntaub ntawv, ntxiv rau cov nroj tsuag fibers, iav Fiber. , carbon, roj hmab, iav thiab lwm yam ntaub ntawv.
Los ntawm ntau xyoo ntawm kev txhim kho thiab kev txhim kho cov khoom siv, cov khoom siv hluav taws xob muaj kev ua haujlwm zoo hauv kev hnav tsis kam thiab tswj suab nrov, thiab tseem tsim nyog rau kev tsav tsheb txhua hnub. Kuj tseem muaj cov plua plav tsawg tsim thiab kev puas tsuaj tsawg rau cov brakes. Txawm li cas los xij, vim yog cov nqi khoom siv thiab lwm yam laj thawj, cov khoom siv hluav taws xob feem ntau kim dua me ntsis, thiab feem ntau yog siv rau cov qauv nruab nrab-rau-siab-kawg thaum lub Hoobkas qub thauj khoom.
semi-hlau nres pads
Lub npe hu ua semi-hlau yog feem ntau yog kwv yees li 30 feem pua -65 feem pua ntawm cov khoom siv sib txhuam siv hauv lub tshuab nres tsheb no yog cov khoom siv hlau - suav nrog tooj liab, hlau thiab lwm yam. Cov yam ntxwv tseem ceeb ntawm hom nres nres yog ceev cua sov dissipation, zoo kub tsis kam, thiab tus nqi qis. Qhov tsis zoo yog vim yog cov khoom siv, lub suab nrov thaum lub sijhawm braking yuav loj, thiab cov khoom siv hlau tseem yuav hnav ntau dua rau lub nres nres.
Txij li thaum semi-hlau nres pads muaj cov yam ntxwv uas tau hais los saum no, muaj ob lub ntsiab lus tseem ceeb ntawm daim ntawv thov tam sim no. Ib qho yog thawj qhov sib txuam ntawm cov nres nres ntawm cov qauv qis kawg thiab nruab nrab-kawg - qhov no yog ib txwm muaj cov yam ntxwv ntawm tus nqi qis. Lwm qhov kev taw qhia yog tsuas yog nyob rau hauv lub tshav pob ntawm kev hloov tsheb nres - vim qhov kub tsis kam ntawm cov hlau nres, nws yog qhov tsim nyog rau cov tsheb ua haujlwm siab lossis siv ntau yam xwm txheej. Tom qab tag nrho, nyob rau hauv qhov kev siv scenario, qhov siab tshaj plaws kub ntawm lub nres nres yuav ncav cuag los yog txawm tshaj 800 degrees Celsius nyob rau hauv feeb. Yog li ntawd, peb tuaj yeem pom tias ntau lub npe hloov kho muaj feem ntau ntawm cov khoom siv hlau rau cov khoom siv nres rau kev tsav tsheb hnyav thiab kev sib tw.
Ceramic brakes
Ceramic nres ncoo tuaj yeem hais tias ua rau tsis muaj hom thiab ib nrab hlau nres nres. Nws cov khoom yog tsim los ntawm cov ntxhia fibers, aramid fibers thiab ceramic fibers thiab lwm yam ntaub ntawv. Ntawm qhov tod tes, vim tias tsis muaj cov khoom siv hlau, lub suab nrov yuav txo qis thaum lub brakes rub tawm ntawm cov brakes. Nyob rau tib lub sijhawm, kev puas tsuaj rau lub nres nres thaum lub sijhawm kev sib txhuam yuav raug txo kom tsawg.
Tsis tas li ntawd, kev sib txhuam coefficient ntawm ceramic nres ncoo tuaj yeem nyob ruaj khov nyob rau hauv qhov kub thiab txias, uas tsis txhob cuam tshuam lub zog ntawm kev sib tsoo los ntawm melting ntawm cov ntaub ntawv ntawm cov organic los yog hlau nres pads thaum lub sij hawm ntev los yog high-speed braking, uas zoo heev txhim kho. kev nyab xeeb. Kuj tseem siv tau ntau dua.
Tau kawg, ceramic nres ncoo tsis yog yam tsis muaj lawv qhov tsis txaus. Qhov loj tshaj qhov tsis zoo yog qhov uas lawv kim heev. Ib txheej ntawm carbon-ceramic brakes yog kaum tawm txhiab daus las ib feeb. Tsis tas li ntawd, nyob rau hauv qhov kub thiab txias ib puag ncig, kev ua tau zoo ntawm ceramic nres ncoo yuav ua rau me ntsis phem dua li ntawm cov hlau nres.
