Kufotokozera ndi mitundu ya brake fluid

Maziko a dongosolo brake galimoto ndi volumetric hayidiroliki pagalimoto kuti kusamutsa kukakamizidwa mu yamphamvu yamphamvu kwa masilindala ntchito mabuleki magudumu.

Zipangizo zina, vacuum boosters kapena hydraulic accumulators, zomwe zimawonjezera khama la dalaivala kukanikiza chopondapo, zowongolera kuthamanga ndi zida zina sizinasinthe mfundo yama hydraulics.

Pistoni ya master cylinder imatulutsa madzimadzi, zomwe zimakakamiza ma pistoni a actuator kuti asunthe ndikukankhira mapepalawo poyang'ana pa ma brake discs kapena ng'oma.

Ma brake system ndi imodzi-akuchita hydraulic drive, mbali zake zimasunthidwa pamalo oyamba pansi pa akasupe obwerera.

Cholinga cha madzimadzi ananyema ndi zofunika kwa izo

Cholingacho ndi chomveka kuchokera ku dzina - kukhala ngati madzimadzi ogwiritsira ntchito ma hydraulic drive a mabuleki ndikuwonetsetsa kuti akugwira ntchito yodalirika pamitundu yosiyanasiyana ya kutentha ndi zochitika zilizonse zogwirira ntchito.

Malinga ndi malamulo a physics, kukangana kulikonse kumasanduka kutentha.

Ma brake pads, amatenthedwa ndi kukangana pamwamba pa diski (ng'oma), kutentha mbali zowazungulira, kuphatikizapo masilindala ogwira ntchito ndi zomwe zili mkati mwake. Ngati chithupsa cha brake chithupsa, nthunzi zake zimafinyira ma cuffs ndi mphete, ndipo madziwo amatulutsidwa m'dongosolo ndi kuthamanga kwambiri. Chopondapo pansi pa phazi lakumanja chidzagwa pansi, ndipo sipangakhale nthawi yokwanira yachiwiri "kupopera".

Njira ina - mu chisanu kwambiri, mamasukidwe akayendedwe amatha kuchulukirachulukira kotero kuti ngakhale vacuum booster singathandize chopondapo kukankha kupyola mu "brake" wandiweyani.

Kuphatikiza apo, TJ iyenera kukwaniritsa izi:

• Khalani ndi malo otentha kwambiri.
• Khalani ndi luso lopopera pa kutentha kochepa.
• Kukhala ndi hygroscopicity yochepa, i.e. kutha kuyamwa chinyezi kuchokera mumlengalenga.
• Khalani ndi mafuta opangira mafuta kuti mupewe kuvala kwamakina pama pistoni ndi masilinda adongosolo.

Mapangidwe a mapaipi a dongosolo lamakono la brake amathetsa kugwiritsa ntchito ma gaskets ndi zisindikizo zilizonse. Mapaipi a brake, ma cuffs ndi mphete amapangidwa ndi zida zapadera zopangira zomwe zimatsutsana ndi magiredi a TJ operekedwa ndi wopanga.

Chenjerani! Zida zosindikizira sizingagwirizane ndi mafuta ndi mafuta, choncho ndizoletsedwa kugwiritsa ntchito mafuta ndi zosungunulira zilizonse poyendetsa mabuleki kapena zinthu zawo. Gwiritsani ntchito brake fluid yokhayo pa izi.

Ananyema zikuchokera madzimadzi

M'magalimoto azaka zapitazi, mchere wa TJ unagwiritsidwa ntchito (osakaniza mafuta a castor ndi mowa mu chiŵerengero cha 1: 1).

Kugwiritsa ntchito mankhwalawa m'magalimoto amakono sikuvomerezeka chifukwa cha kukhuthala kwawo kwakukulu (kukhuthala pa -20 °) ndi malo otsika otentha (osakwana 100 °).

Maziko a TF yamakono ndi polyglycol (mpaka 98%), nthawi zambiri silikoni (mpaka 93%) ndi kuwonjezera zowonjezera zomwe zimasintha khalidwe la maziko, kuteteza pamwamba pa njira zogwirira ntchito kuti zisawonongeke ndikupewa makutidwe ndi okosijeni. TF yokha.

N'zotheka kusakaniza ma TJ osiyanasiyana pokhapokha atapangidwa mofanana. Apo ayi, mapangidwe a emulsions omwe amasokoneza ntchito ndizotheka.

Kulemba

Gululi limatengera miyezo yapadziko lonse ya DOT yotengera kutentha kwa FMVSS ndi gulu la SAEJ viscosity.

Mogwirizana ndi iwo, madzi ananyema amakhala ndi magawo awiri: kinematic mamasukidwe akayendedwe ndi kuwira mfundo.

Yoyamba ndi yomwe imapangitsa kuti madzi azitha kuyendayenda m'mizere yotentha kuchokera -40 ° mpaka +100 madigiri.

Chachiwiri - kupewa nthunzi maloko zomwe zimachitika pa otentha TJ ndi kuchititsa ananyema kulephera.

Kutengera izi, kukhuthala kwa TF iliyonse pa 100 ° C kuyenera kukhala osachepera 1,5 mm²/s ndi -40 ° C - osapitirira 1800 mm²/s.

Mapangidwe onse opangidwa ndi glycol ndi polyglycol ndi a hygroscopic, i. amakonda kuyamwa chinyezi kuchokera ku chilengedwe.

Ngakhale galimoto yanu siimachoka pamalo oimikapo magalimoto, chinyezi chimalowabe m'dongosolo. Kumbukirani bowo "lopuma" mu chivindikiro cha thanki.

Mitundu yonse ya TJ ndi yapoizoni !!!

Malinga ndi muyezo wa FMVSS, kutengera chinyezi, ma TJs amagawidwa kukhala:

• "Dry", mu fakitale ndipo mulibe chinyezi.
• "Wonyowa", atamwa mpaka 3,5% yamadzi panthawi yautumiki.

Malinga ndi miyezo ya DOT, mitundu yayikulu ya TA imasiyanitsidwa:

1. DOT 3. Mabuleki amadzimadzi otengera ma glycol osavuta.

Kutentha kwamphamvu, ^оC:

• "zouma" - osachepera 205;
• "wonyowa" - osachepera 140.

Kukhuthala, mm²/ndi:

• "yonyowa" pa +100⁰C - osachepera 1,5;
• "wonyowa" pa -40⁰C - osapitirira 1800.

Amatenga msanga chinyezi ndipo chifukwa cha izi, malo otentha amakhala ochepa pakapita nthawi yochepa.

Madzi a DOT 3 amagwiritsidwa ntchito m'magalimoto okhala ndi mabuleki a ng'oma kapena ma disc brakes pamawilo akutsogolo.

Avereji ya moyo wautumiki ndi wosakwana zaka ziwiri. Zamadzimadzi za m'kalasili ndizotsika mtengo ndipo zimatchuka.

2. DOT 4. Kutengera ntchito yapamwamba ya polyglycol. Zowonjezera zimaphatikizapo boric acid, yomwe imachepetsa madzi ochulukirapo.

Kutentha kwamphamvu, ^оC:

• "zouma" - osachepera 230;
• "wonyowa" - osachepera 150.

Kukhuthala, mm²/ndi:

• "yonyowa" pa +100⁰C - osachepera 1,5;
• "wonyowa" pa -40⁰C - osapitirira 1500.

 

Mtundu wodziwika kwambiri wa TJ pamagalimoto amakono okhala ndi mabuleki a disk "mu bwalo."

Chenjezo. Ma TJ onse opangidwa ndi glycol ndi polyglycol amakhala aukali kupenta.

3. DOT 5. Zopangidwa pamaziko a silikoni. Zosagwirizana ndi mitundu ina. Kuphika pa madigiri 260 ^оC. Sizingawononge utoto kapena kuyamwa madzi.

Pamagalimoto ambiri, monga lamulo, sichimagwiritsidwa ntchito. TJ DOT 5 imagwiritsidwa ntchito pamitundu yapadera yamagalimoto omwe amagwira ntchito kutentha kwambiri.

4. DOT 5.1. Kutengera ma glycols ndi ma polyesters. Malo otentha amadzimadzi "ouma" 260 ^оC, "wothira" madigiri 180. Kinematic mamasukidwe akayendedwe ndi otsika kwambiri, 900 mm2/s pa -40 ^оC.

Amagwiritsidwa ntchito pamagalimoto amasewera, magalimoto apamwamba komanso njinga zamoto.

5. DOT 5.1/ABS. Zapangidwira magalimoto okhala ndi anti-lock braking system. Amapangidwa pamaziko osakanikirana omwe ali ndi glycols ndi silikoni okhala ndi phukusi la anti-corrosion additives. Imakhala ndi mafuta abwino, otentha kwambiri. Glycol m'munsi imapangitsa gulu ili la TJ hygroscopic, choncho moyo wawo wautumiki umangokhala zaka ziwiri kapena zitatu.

Nthawi zina mumatha kupeza madzi am'nyumba a brake okhala ndi mayina a DOT 4.5 ndi DOT 4+. Makhalidwe amadzimadziwa ali mu malangizo, koma chizindikiro choterocho sichinaperekedwe ndi machitidwe apadziko lonse.

Posankha brake fluid, muyenera kutsatira malangizo a wopanga galimoto.

Mwachitsanzo, muzinthu zamakono za "AvtoVAZ" zimagwiritsidwa ntchito "kudzaza koyamba", mtundu wa TJ DOT4, SAEJ 1703, FMSS 116 wa mtundu wa ROSDOT ("Tosol-Sintez", Dzerzhinsk) amagwiritsidwa ntchito.

Kusamalira ndi kubwezeretsa ma brake fluid

Mulingo wa brake fluid ndi wosavuta kuwongolera ndi max ndi min marks pamakoma a chosungira chomwe chili pa silinda yayikulu ya brake.

Pamene mlingo wa TJ ukuchepa, uyenera kuwonjezeredwa.

Ambiri amatsutsa kuti madzi aliwonse amatha kusakanikirana. Izi sizowona. DOT 3 class TF iyenera kuwonjezeredwa ndi zomwezo, kapena DOT 4. Zosakaniza zina zilizonse sizovomerezeka, ndipo ndizoletsedwa ndi madzi a DOT 5.

Mawu olowa m'malo mwa TJ amatsimikiziridwa ndi wopanga ndipo akuwonetsedwa mu malangizo oyendetsera galimoto.

"Kupulumuka" kwa zakumwa zochokera ku glycol ndi polyglycol kumafika zaka ziwiri kapena zitatu, zokhazokha za silicone zimatha mpaka khumi ndi zisanu.

Poyamba, TJs iliyonse imakhala yowonekera komanso yopanda mtundu. Kudetsa kwamadzimadzi, kutayika kwa kuwonekera, mawonekedwe a matope m'malo osungira ndi chizindikiro chotsimikizika kuti brake fluid iyenera kusinthidwa.

Muutumiki wamagalimoto okonzeka bwino, kuchuluka kwa hydration ya brake fluid kudzatsimikiziridwa ndi chipangizo chapadera.

Pomaliza

A serviceable brake system nthawi zina ndi chinthu chokhacho chomwe chingakupulumutseni ku zotsatira zoyipa kwambiri.

Ngati ndi kotheka, yang'anirani mtundu wamadzimadzi mu mabuleki agalimoto yanu, yang'anani nthawi yake ndikuyikanso ngati kuli kofunikira.
