Kakawanda sei iyo brake fluid inoshandurwa?

Sei uchichinja brake fluid?

Ngatitangei nezvinokosha. Brake fluid inoshanda sedhizaini inofambisa kubva kune master brake cylinder (GTE) kune vashandi. Mutyairi anotsikirira pedal, GTE (piston iri nyore kwazvo mudzimba ine valve system) inotumira kudzvanywa kwemvura nemumitsetse. Iyo mvura inotamisa kudzvanywa kumasilinda anoshanda (calipers), mapistoni anowedzera uye anoparadzira mapadhi. Mapadhi anodzvinyirirwa nesimba kune nzvimbo yekushanda yemadhisiki kana madhiramu. Uye nekuda kwekukakavadzana pakati pezvinhu izvi, mota inomira.

Izvo zvakakosha zveiyo brake fluid zvinosanganisira:

• incompressibility;
• kuramba tembiricha yakaderera uye yakakwira;
• kusarerekera maitiro kune epurasitiki, rabha uye simbi zvikamu zvehurongwa;
• yakanaka lubricating properties.

Chenjerera: pfuma ye incompressibility yakanyorwa kutanga. Izvi zvinoreva kuti, mvura inofanira kujeka, pasina kunonoka uye kunyatsoendesa kumanikidziro kumasilinda anoshanda kana calipers.

Brake fluid ine chinhu chimwe chisingafadzi: hygroscopicity. Hygroscopicity ndiko kugona kuunganidza hunyoro kubva kunharaunda.

Mvura muhuwandu hwebhureki fluid inoderedza kupikisa kwayo kuvira. Semuenzaniso, mvura yeDOT-4, inonyanya kuzivikanwa nhasi, haifashaidzi kusvika yasvika patembiricha ye230°C. Uye ichi ndicho chidimbu chinodiwa cheUS Dhipatimendi rekutakura chiyero. Iko kuvira chaiko kwemvura yakanaka yebhureki inosvika 290°C. Nekuwedzera chete 3,5% yehuwandu hwehuwandu hwemvura kubhureki fluid, nzvimbo yekubikira inodonha kusvika +155 °C. Iyo inenge 30%.

Iyo braking system inoburitsa yakawanda yekupisa simba panguva yekushanda kwayo. Izvi zvine musoro, nekuti simba rekumisa rinobva mukukweshana nechisimba chakakura chekusunga pakati pemapedhi nedhisiki (drum). Zvinhu izvi dzimwe nguva zvinopisa kusvika 600 ° C muchikamu chekusangana. Iyo tembiricha kubva kumadhisiki nemapadhi inotamirwa kune macalipers nemasilinda, ayo anopisa mvura.

Uye kana nzvimbo yekuvira yasvika, mvura inofashaira. Iyo gasi plug mafomu muhurongwa, iyo mvura inorasikirwa neiyo incompressibility pfuma, iyo pedal ichatadza uye mabhureki anotadza.

Zvikamu zvekutsiva

Kangani bhureki fluid inofanira kuchinjwa? Paavhareji, hupenyu hwesevhisi yeiyi tekinoroji fluid isati yaunganidzwa yemvura yakaoma ndeye makore matatu. Izvi ndezvechokwadi kune zvakasiyana-siyana zveglycol zvakadai seDOT-3, DOT-4 uye kusiyana kwayo, pamwe neDOT-5.1. DOT-5 uye DOT-5.1/ABS zvinwiwa, izvo zvinoshandisa silicone base sehwaro, zvakanyanya kupikisa kuunganidzwa kwemvura, zvinogona kuchinjwa kwemakore mashanu.

Kana motokari ichishandiswa zuva rega rega, uye mamiriro ekunze munharaunda anonyanya kunyorova, zvinokurudzirwa kuderedza nguva pakati pezvinotevera zvinotsiva zvebhureki fluid ne30-50%. Glycolic fluids pasi pemamiriro akaoma ekushanda kwegadziriro inoda kuchinjwa makore ose 1,5-2, silicone fluids - 1 nguva mumakore 2,5-4.

Unoziva sei kana yave nguva yekuchinja brake fluid yako?

Kana iwe usingazivi nguva iyo brake fluid yakagadziridzwa pakupedzisira (kukanganwa kana kungotenga motokari), pane nzira mbiri dzekuona kana inguva yekuchinja.

1. Shandisa brake fluid analyzer. Ichi ndicho chigadziri chakareruka chinofungidzira chikamu chehunyoro muvhoriyamu nemagetsi kuramba ethylene glycol kana silicone. Kune akati wandei mavhezheni eiyi brake fluid tester. Kune zvinodiwa zvemumba, iyo iri nyore ndiyo yakakodzera. Sezvakaratidzwa nemaitiro, kunyange mudziyo wakachipa une chikanganiso chisina basa, uye unogona kuvimbwa nawo.
2. Ongorora nemeso mabhureki fluid. Isu tinosunungura plug uye tinotarisa mutangi rekuwedzera. Kana iyo mvura ine makore, yarasa kujeka, yakasviba, kana yakanaka inclusions inooneka muhuwandu hwayo, isu tinoishandura.

Rangarira! Zviri nani kukanganwa kuchinja oiri yeinjini wopinda mukugadzirisa injini pane kukanganwa nezve brake fluid woita tsaona. Pakati pese mvura yetekinoroji mumotokari, inonyanya kukosha ndeye brake fluid.
