Zamkatimu

Nthawi zambiri, oyendetsa okha sadziwa chimene madzimadzi wodzazidwa mu posungira dongosolo brake. Ndipo pamene kuli kofunikira kuwonjezera (pambuyo pa kukonzanso kapena kutaya mabuleki), funso lomveka limakhalapo: kodi kwenikweni, ndi chiyani mu thanki, ndipo chingasakanizidwe ndi chiyani? Pansipa tiyesa kuyankha mwachidule funsoli: ndizotheka kusakaniza brake fluid kuchokera kwa opanga osiyanasiyana.

Mitundu yamadzimadzi ma brake ndi mawonekedwe awo

Pakali pano, madzimadzi omwe amagwiritsidwa ntchito kwambiri mabuleki amagawidwa motsatira ndondomeko ya US Department of Transportation (Department of Transportation). Chidule cha DOT.

Malinga ndi gulu ili, magalimoto opitilira 95% masiku ano amagwiritsa ntchito chimodzi mwamadzimadzi awa:

  • DOT-3;
  • DOT-4 ndi zosintha zake;
  • DOT-5;
  • DOT-5.1.

Zakumwa zam'nyumba "Neva" (zofanana ndi DOT-3, nthawi zambiri zimasinthidwa ndi zowonjezera zomwe zimawonjezera kuzizira), "Rosa" (zofanana ndi DOT-4) ndi zina zotero zikukhala zochepa. Chifukwa chake chinali pafupifupi kusintha kwapadziko lonse kwa opanga aku Russia kuti alembe molingana ndi American standard.

Mwachidule lingalirani mawonekedwe akulu ndi kukula kwamadzimadzi a mabuleki pamwambapa.

  1. DOT-3. Glycol fluid yachikale. Amagwiritsidwa ntchito kwambiri m'magalimoto akunja azaka zapakati pa 15-20 komanso mu classics ya VAZ. Ali ndi high hygroscopicity (kutha kudziunjikira madzi mu kuchuluka kwake). Kuwira kwa madzi atsopano ndi pafupifupi 205 ° C. Pambuyo pakuwunjikana kwamadzi opitilira 3,5% amadzi onse amadzimadzi, malo otentha amatsika mpaka 140 ° C. Amachita mwaukali ku mapulasitiki ndi ma rubber.
  2. DOT-4. Amagwiritsidwa ntchito m'magalimoto atsopano. Pansi pake ndi polyglycol. Imakhala ndi kukana kwambiri kuyamwa kwa chinyezi kuchokera ku chilengedwe. Ndiko kuti, kumatenga nthawi yayitali (pafupifupi, kwa miyezi isanu ndi umodzi kapena chaka). Komabe, zowonjezera zomwe zimachepetsa hygroscopicity ndi kuchuluka kwamphamvu kwamankhwala zidakulitsa madzi awa. Pa -40 ° C, kukhuthala kwake kumakhala kokwera pang'ono kuposa madzi ena a DOT. Kuwira kwa madzi "ouma" ndi 230 ° C. Chinyezi (kuposa 3,5%) chimachepetsa kuwira mpaka 155 ° C.
  3. DOT-5. silicone madzi. Satenga chinyezi kuchokera ku chilengedwe. Ena kudzikundikira chinyezi ndi zotheka mu mawonekedwe a condensate. Komabe, madzi samasakanikirana ndi silicon base ndi precipitates (zomwe zingayambitsenso zovuta). DOT-5 madzimadzi salowerera ndale. Kuphika pa kutentha kosachepera 260 ° C. Ili ndi madzi abwino pa kutentha kochepa.

    1. DOT-5.1. Zosinthidwa pamagalimoto amasewera (kapena magalimoto atsopano) mawonekedwe a glycol. Madziwo amakhala otsika kwambiri mamasukidwe akayendedwe. Ingowira pambuyo podutsa 260 ° C (pa 3,5% chinyezi, kutentha kumatsika mpaka 180 ° C). Ili ndi kukana bwino kwa kutentha kochepa.

Madzi awiri omalizira amagwiritsidwa ntchito pokhapokha ngati izi zatsimikiziridwa ndendende ndi malangizo a galimoto. Zamadzimadzizi zimatha kusokoneza ma brake system akale, pomwe kuchepekera kumapangitsa kuti makinawo asamagwire bwino ntchito ndikupangitsa kuti ma brake caliper ndi piston atayike.

Kusakanikirana kwamadzimadzi amabuleki kuchokera kwa opanga osiyanasiyana

Nthawi yomweyo za chinthu chachikulu: zonse zomwe zimaganiziridwa kuti ma brake fluid, kupatula DOT-5, zitha kusakanikirana pang'ono, mosasamala kanthu za wopanga. Ndi kalasi yomwe ili yofunika, osati wopanga.

Zosintha zokhala ndi maziko osiyanasiyana ndizosemphana kwenikweni. Mukasakaniza zitsulo za silicone (DOT-5) ndi glycol (zosankha zina), kugawa kudzachitika ndi zotsatira zake zonse. Chifukwa cha kusiyanasiyana, madziwo adzachita mosiyana akatenthedwa ndi kukhazikika. Kuthekera kwa kupanga mapulagi am'deralo kumawonjezeka nthawi zambiri.

Zamadzimadzi DOT-3, DOT-4 ndi DOT-5.1 akhoza kusakanikirana kwakanthawi. Onetsetsani kuti muwone ngati madziwa adapangidwa kuti azigwira ntchito ndi ABS ngati muli ndi makinawa. Sipadzakhala zotsatira zovuta. Komabe, izi zitha kuchitika pokhapokha ngati pakufunika komanso kwakanthawi kochepa. Ndipo pokhapokha ngati madzi ofunidwa sapezeka pazifukwa zina. Koma ngati galimoto yanu imagwiritsa ntchito DOT-4 brake fluid kuchokera ku fakitale, ndipo n'zotheka kuigula, simuyenera kusunga ndi kutenga DOT-3 yotsika mtengo. M'kupita kwa nthawi, izi zidzatsogolera ku chiwonongeko chofulumira cha zisindikizo za dongosolo kapena mavuto mu dongosolo la ABS.

Komanso, simuyenera kugula DOT-5.1 yodula ngati dongosolo silinapangidwe. Sizomveka. Kupanga gasi ndi kulephera kwadzidzidzi kwa brake sikungachitike ngati dongosolo lili bwino. Komabe, kusiyana pafupifupi 2 nthawi otsika kutentha mamasukidwe akayendedwe kungayambitse depressurize dongosolo ananyema. Kodi izi zimachitika bwanji? Pakutentha koipa, zosindikizira za rabara zimataya mphamvu zake. Pamagalimoto opangira DOT-3 kapena DOT-4, madziwo amakhuthala molingana. Ndipo "brake" wandiweyani, ngati umayenda kudzera mu zisindikizo zoumitsidwa zoperekedwa, ndiye pang'ono. Ngati mumadzaza otsika mamasukidwe akayendedwe DOT-5.1, ndiye m'nyengo yozizira muyenera kukonzekera kutayikira kwake. Makamaka mu chisanu kwambiri.

Zosintha zosiyanasiyana za DOT-4 (DOT-4.5, DOT-4+, etc.) zitha kusakanikirana popanda zoletsa. Pankhani yofunika kwambiri ngati mapangidwe amadzimadzi a brake, opanga onse amatsatira miyezo. Ngati zalembedwa pa chitini kuti ndi DOT-4, ndiye, kupatulapo ang'onoang'ono, zolembazo zimakhala ndi zigawo zomwezo, mosasamala kanthu za wopanga. Ndipo kusiyana kwa mankhwala sikuyenera kukhudza kuyanjana mwanjira iliyonse.
