Brakes yuav tsum ib txwm ntseeg tau. Kev nyab xeeb ntawm tus neeg tsav tsheb thiab cov neeg caij tsheb yog nyob ntawm lawv tus mob. Lub tshuab yuav tsum tiv taus qhov siab tshaj plaws, kev nres tsheb yuav tsum ua haujlwm zoo hauv txhua qhov xwm txheej. Txawm li cas los xij, txawm tias niaj hnub disk nodes tsis tuaj yeem khav theeb ntawm cov khoom zoo no. Txawm hais tias lawv cov kev ua haujlwm siab, qee zaum lawv ua lawv txoj haujlwm thiab kev ua haujlwm tsis zoo hauv cov xwm txheej tseem ceeb. Txhawm rau them nyiaj rau qhov tsis txaus, cov khoom siv ceramic thiab cov ntaub qhwv tau siv hauv cov tsheb niaj hnub. Ceramic brakes muaj peev xwm ua haujlwm tau zoo nyob rau hauv txhua qhov xwm txheej, thiab qhov tseem ceeb tshaj plaws - ntawm qhov kub thiab txias.

Yog vim li cas thiaj pom

Cov khoom no tau pib tshwm sim hauv khw rau ob lub laj thawj tseem ceeb. Thawj qhov laj thawj yog asbestos, los ntawm cov khoom uas tau tsim, thiab nws qhov kev puas tsuaj rau tib neeg. Qhov thib ob yog ncaj qha braking. Cia peb saib cov ntsiab lus no.

Kev phom sij asbestos

kab ntev tau uacov khoom xws li asbestos (nws yog ib qho khoom siv ntxiv). Cov kws tshaj lij paub zoo txog qhov tsis zoo ntawm cov tshuaj rau tib neeg kev noj qab haus huv thiab tsis yog xwb. Qhov tseem ceeb tshaj plaws yog asbestos yog ib qho muaj zog carcinogen. Yog, thiab kev ua haujlwm braking ntawm cov khoom cuam tshuam tsis zoo. Cov ntaub qhwv no tsis tshua muaj txiaj ntsig.

Vim li no, nyob rau xyoo 80s hauv North America, nrog rau hauv Tebchaws Europe, kev sib tw nquag tau ua haujlwm hu rau kev tso tseg ntawm asbestos. Automotive nres ncoo yog thawj tus raug ntaus nrog cov tshuaj asbestos.

Zoo braking

theem kev tuav tau nce, lub tsheb tau muaj zog dua. Cov neeg tsav tsheb muaj kev vibration me ntsis thiab tsis xis nyob los ntawm kev ua haujlwm ntawm lub tshuab nres. Tom qab qhov nce ntawm kev tsav tsheb, cov kauj ruam tom ntej yog los ua kom cov kev xav tau ntawm kev ua haujlwm nres. Qhov no tau coj cov tuam txhab tsheb pib tshawb fawb cov ntaub ntawv tshiab.

Qhov sib txawv ntawm cov ceramics

Lub tshuab nres tsheb muaj peb lub ntsiab lus. Qhov no yog disc, caliper, ncoo. Hauv cov tsoos disc nres, lub caliper thiab disc yog hlau. Cov ntaub qhwv yog tsim los ntawm cov hlau tshwj xeeb-asbestos sib tov. Thaum braking, kev sib txhuam tshwm sim ntawm cov ntaub qhwv thiab cov hlau ntawm cov disc, uas ua rau muaj cua sov. Cov cua sov no ua rau ob qho tib si cov ntaub qhwv thiab cov disc nws tus kheej heev. Thaum tshav kub kub muaj qhov cuam tshuam tsis zoo rau kev ua haujlwm braking. Txhawm rau txo qhov kub thiab txias, cov neeg tsim khoom tsim cov ventilated discs. Kev siv cov asbestos kuj tso cai rau cov ntaub qhwvua haujlwm nyob rau hauv qhov kub thiab txias.

Tab sis nyob rau hauv cov xwm txheej nyuaj, tag nrho cov kev ntsuas no tsis txaus. Yog tias koj xav tau kom qeeb qeeb, qhov kub thiab txias yuav ntau dua li qhov tso cai. Cov neeg tsim khoom tau nthuav tawm cov ntaub ntawv tshiab tshaj plaws uas tuaj yeem sib npaug ntawm qhov kub thiab txias, nrog rau kev muab cov kev sib txhuam tsim nyog. Qhov no yog li cas ceramic brakes tau yug los. Cov no yog cov ntaub qhwv rau cov ntaub qhwv thiab cov khoom siv ceramic.

Tsev tsim khoom

Cov khoom no yog ua raws li hauv qab no. Nyob rau hauv ib lub siab, ib tug sib tov ntawm hlau chips nrog ib tug ceramic puag yog tsim. Tom ntej no, lub resulting loj yog ci nyob rau hauv high kub. Qhov tshwm sim yog cov khoom siv hluav taws xob ceramic nrog kub ua haujlwm thiab lwm yam khoom siv tau zoo.

Ntawm cov yam ntxwv tseem ceeb ntawm ceramic brakes, ib qho tuaj yeem tawm ib theem qis ntawm lub suab nrov thiab kev co piv rau cov khoom siv hlau tsoos. Lwm qhov ntxiv yog kev muab cov coefficient tsis tu ncua ntawm kev sib txhuam hauv txhua qhov kub thiab txias. Tsis tas li ntawd, cov ntaub qhwv ceramic yog maj mam rau ntawm cov discs vim tsis muaj cov khoom hlau. Hloov cov hlau uas muaj hlau, cov chaw tsim khoom siv lub hauv paus tooj liab.

Kev hloov kho

Tam sim no ntau yam kev hloov kho ntawm cov tshuab nres ceramic tau tsim. Lawv txawv nyob rau hauv kev tsav tsheb style - cov no yog brakes rau txhoj puab heev nroog tsav tsheb, kev ua si nawv, raws li zoo raws li rau nws pib huab. Thawj qhov zoo tagnrho rau kev tsav tsheb hauv nroog thiab kev tsav tsheb txhua hnub. Qhov thib ob yog tsim raukev teeb tsa ntawm lub tsheb muaj zog, lwm tus muaj tus nqi siab thiab yog tsim los rau cov tsheb sib tw. Ceramic brakes tsis yog siv rau hauv kev lag luam tsheb.

Qhov zoo thiab qhov tsis zoo

Pib nrog cov txiaj ntsig meej. Kev tshuaj xyuas hais tias vim yog cov khoom siv tshiab, cov ntaub qhwv thiab cov discs tuaj yeem txo qhov hnyav thiab ncua kev ncua. Qhov tseeb yog tias ceramic nres disc yog qhov sib zog dua li cov hlau. Nyob rau hauv tus txheej txheem ntawm kev txo kev ceev nrog carbon-ceramic brakes, yog xyaum tsis muaj plua plav emission, tshuaj xyuas hais. Ua kom cov coefficient ntawm kev sib txhuam thiab efficiency thaum rhuab. Ceramic discs muaj lub neej ua haujlwm ntev, vim tias tsis muaj hlau hauv cov khoom xyaw.

Tsis muaj cons. Lub ntsiab tsis zoo tau sau tseg los ntawm kev tshuaj xyuas yog tus nqi siab piv rau cov khoom siv hlau tsoos thiab cov khoom siv. Yuav kom tau txais txiaj ntsig zoo tshaj plaws ntawm ceramic brakes, lawv yuav tsum tau ua kom sov. Lub creak yuav tshwm sim thaum ua haujlwm.

Myths and reality

Muaj ntau cov lus dab neeg ntawm cov neeg tsav tsheb txog cov nres no. Cia peb sim tshem lawv. Muaj kev ntseeg ruaj khov tias ceramic disc nres tsuas yog ua tau zoo tshaj plaws ntawm cov tsheb ua si, vim tias lawv yuav tsum tau sov so. Nws tseem ntseeg tau tias cov ntaub qhwv ntsej muag nruj heev rau cov discs. Qhov no tsis muaj tseeb. Muaj sab nraum zoov ceramics. Nws muaj kev sib txhuam zoo heev txawm tias qhov kub thiab txias braking. Cov ntaub qhwv no tuaj yeem siv tau txhua hnub.

Cov lus dab neeg tom ntej yog tias cov ceramics tsuas yog ntsia tau rau hauv tandem nrog tib lub ceramics. Thiab qhov no kuj yog qhov tsis ncaj ncees lawm. Ceramic brakes "Audi" nyob rau hauv daim ntawv ntawm cov ntaub qhwv tau tshwm sim sai dua li cov discs. Cov ntaub qhwv ua haujlwm zoo nrog cov ntaub qhwv hlau, thiab kev ua haujlwm tau zoo heev.

Tom ntej no, qee tus tswv yws tias cov ntaub qhwv no tua cov disc. Niaj hnub no nws yog ib qho nyuaj rau taug qab qhov twg raws nraim cov prejudices los ntawm. Tab sis tom qab ntau txhiab qhov kev sim, cov kws tshaj lij tau pom tias BMW ceramic brakes hnav lub disc sib npaug.
