Yuav ua li cas yog nres kua? Qhov no yog ib tug tshwj xeeb neeg sawv cev rau lub tsheb nres. Nws yog nyob rau hauv lub kua hauv lub xeev thiab presses lub brakes thaum lub pedal yog pressed. Nyob rau hauv lwm yam lus, nws muab ib qhov txuas ntawm lub commands ntawm tus neeg tsav tsheb thiab cov nres mechanism. Yog hais tias muaj yog ib tug ua txhaum ntawm no kev twb kev txuas, lub tsheb cia li tsis nres. Qhov no yuav tshwm sim nyob rau hauv cov kev tshwm sim ntawm ntau cua sov ntawm lub kua, tom qab uas lub chav hauv lub nres mechanism tshwm. Nws ua rau ib tug compressible system thiab lub substance yuav tsis tau nyob qib qub nias lub pedal nrog ib tug ntse slowdown thiab slammed rau tus brakes. Qhov no yog vim li cas nres kua - yog ib tug me me, tab sis tseem ceeb heev kev nthuav dav ntawm lub tsheb. Yog tsis muaj nws, tus neeg tsav tsheb yuav tsis tau tsiv mus nyob yam xyuam xim nyob rau hauv tus kwj. Nyob rau hauv lwm yam lus, muaj yog tsis muaj cov nres kua - tsis muaj brakes.
Nres kua yog muab faib ua ob peb hom, uas txawv nyob rau hauv qhov kub ntawm nws cov cua kub. Yog li ntawd, cov thawj kev faib cais lub substance rau "ntub" thiab "qhuav" kua. Lawm, lub "qhuav" kua muaj xws li dej tsawg, thiab "hydrated" nws kev faib ua feem yog 3-4%. Ntxiv mus, ob tug nres kua tseem muab faib ua plaub pawg: DOT 3, DOT 4, DOT 5 thiab DOT 5.1. Tus thawj hom mas tus nqi qis tshaj kub: 205 degrees Celsius rau "qhuav" thiab 140 - rau "noo". Raws li los ntawm cov DOT 4 (rau cov tsheb nrog disc brakes). Loj loads yuav tsum tau ntau dua kub, thiab yog li ntawd, ob hom ntawm nres kua yog xam los ntawm 155 thiab 230 degrees Celsius. Nrog kev xav txog kua DOT 5.1, nws muaj peev xwm yuav nrhiav tau nyob rau hauv cov kev ua si tsheb, xws li cov M6 rau lub BMW, lub Ferrari F458, lub Porsche 911 , thiab lwm tus neeg. Tab sis lub penultimate views ntawm lub ntau lawm tshuab tsis siv. Feem ntau cov yuav, DOT 5 yog muab tso rau hauv kev sib tw tsheb thiab kev ua si tsheb hloov kev hloov kho. Los ntawm txoj kev, nws yog tau hais tias nyob rau hauv lub Bugatti Veyron tsim nyog lub zoo meej tshaj plaws kua. Koj ua tau zoo yog paub tseeb hais tias.
Yog li ntawd, peb tau kawm cov views, tab sis cov nqe lus nug seem "dab tsi nres kua yog zoo dua?". Yuav ua li cas los teb nws? Ntawm cov hoob kawm, muab zoo dua braking DOT 5. Nrog kev xav txog cov ntau lawm tsheb, nws yog DOT 5,1. Lwm yam kev kua muaj ntau haum rau tej yam kev mob thiab txheem ntawm lub tsheb yog tsis tsim kev zoo ceev thiab huab teeb meem.
Summing li, kuv xav them sai sai mus rau lub Cheebtsam hais tias ua li tus nres kua. Muaj pes tsawg leeg ntawm no cov ntaub ntawv uas yog tag nrho ntawm ntau yam. Piv txwv li, silicone polymers muaj nres kua, thiab muaj glikogelevye polyglycols. Tab sis lawv muaj ib tug tshaj plaws nyob rau hauv ntau - ib tug additive. Lawv yog cov corrosion resistant thiab lubricants.
Yuav ua li cas yog lub ntsiab muaj nuj nqi ntawm tus nres kua? Ntawm cov hoob kawm, nws yog kev nyab xeeb thaum tsav tsheb. Raws li hais saum toj no, tsis muaj qhov no tshuaj tsis muaj brakes. Yog li ntawd, nws yog ib qho tseem ceeb los kho nws nrog tshwj xeeb mloog vim hais tias ib tug los yuav ua tau kom yus txim. Yuav kom ib yam dab tsi zoo yuav tsis tau, thiab siv DOT 3 kua nyob rau hauv kev ua si tsheb, vim hais tias loj overloads ua rau ntev li cua sov.
Nws yuav tsum tau muab sau tseg hais tias koj yuav ntse sib txawv kua, tshwj tsis yog tias lawv yog cov nyob rau tib lub hauv paus. Yog hais tias cov ntaub ntawv nyob rau hauv lub daim ntawv lo yog tsis tam sim no, nws tsis yog muaj nqis rau tus uas muaj feem yuav!
