mhedziso

Hwaro hweiyo brake system yemotokari ndeye volumetric hydraulic drive inotamisa kudzvanywa mu master cylinder kumasilinda anoshanda emabhureki mavhiri.

Zvishandiso zvekuwedzera, vacuum boosters kana hydraulic accumulators, izvo zvinoramba zvichiwedzera kuedza kwemutyairi kudzvanya brake pedal, zvinodzvinyirira zvigadziriso uye zvimwe zvishandiso hazvina kuchinja musimboti wehydraulics.

Iyo master cylinder piston inoburitsa fluid, iyo inomanikidza actuator pistons kufamba uye kudzvanya mapedhi pakatarisana nepamusoro pemabhureki disc kana zvigubhu.

Iyo brake system ndeye-inobata hydraulic drive, zvikamu zvaro zvinotamirwa kunzvimbo yekutanga pasi pechiito chekudzoka zvitubu.

Chinangwa chebhureki fluid uye zvinodiwa pairi

Icho chinangwa chakajeka kubva kune zita - kushanda semvura inoshanda ye hydraulic drive yemabhureki uye kuve nechokwadi chekushanda kwavo kwakavimbika mumhando dzakasiyana dzekushisa uye chero mamiriro ekushanda.

Zvinoenderana nemirairo yefizikisi, chero kupokana kunopedzisira kwave kupisa.

Mabhureki mapedhi, anopisa nekukweshera pamusoro peiyo disc (dhiramu), kupisa zvikamu zvakapoteredza, kusanganisira macylinders anoshanda uye zviri mukati mawo. Kana iyo brake fluid yakafashaira, mhute dzayo dzinosvina ma cuffs uye zvindori, uye mvura yacho inoburitswa kubva muhurongwa nekuwedzerwa kwakanyanya. Iyo pedal pasi petsoka yerudyi ichawira pasi, uye panogona kunge pasina nguva yakakwana yechipiri "kupomba".

Imwe sarudzo ndeyokuti muchando chakanyanya, viscosity inogona kuwedzera zvakanyanya zvekuti kunyange vacuum booster haizobatsiri pedal kusundira mukati me "brake" yakakora.

Mukuwedzera, iyo TJ inofanirwa kusangana nemamiriro anotevera:

Iva nepamusoro pekubikira.
Chengetedza kugona kupomba pane tembiricha yakaderera.
Possess low hygroscopicity, i.e. kukwanisa kutora unyoro kubva mumhepo.
Iva nemafuta ekuzora kudzivirira kupfekedzwa kwemakanika kwenzvimbo dzepiston uye masilinda eiyo system.

Dhizaini yemapaipi emazuva ano brake system inobvisa kushandiswa kwechero gaskets uye zvisimbiso. Mabhureki hoses, cuffs uye zvindori zvinogadzirwa neakakosha zvinhu zvekugadzira izvo zvinopesana nemagiredhi eTJ anopihwa nemugadziri.

Attention! Zvisimbiso hazvisi mafuta uye peturu inodzivirira, saka zvinorambidzwa kushandisa peturu uye chero zvinonyungudutsa zvekutsvaira mabhureki masisitimu kana zvinhu zvavo zvega. Shandisa brake fluid yakachena chete pane izvi.

Akamedura Urume sezvamunoita

Mumotokari dzezana remakore rapfuura, mineral TJ yakashandiswa (musanganiswa wemafuta e-castor uye doro muchiyero che1: 1).

Kushandiswa kwemakemikari akadaro mumotokari dzemazuva ano hakugamuchirwi nekuda kwepamusoro kinetic viscosity (yakakora pa -20 °) uye yakaderera kuvira (pasi pe100 °).

Hwaro hweTF yemazuva ano ndeye polyglycol (inosvika 98%), isingawanzo silicon (kusvika 93%) pamwe nekuwedzera kwezvinowedzera zvinovandudza hunhu hwechigadziko, kuchengetedza nzvimbo dzemashandisirwo ekushanda kubva mukuora uye kudzivirira oxidation ye. TF pachayo.

Zvinokwanisika kusanganisa maTJ akasiyana chete kana akaitwa panheyo imwechete. Kana zvisina kudaro, kuumbwa kwe emulsions iyo inokanganisa kushanda kunogoneka.

Kurongwa

Iyo kupatsanurwa kwakavakirwa papasi rose DOT zviyero zvinoenderana neFMVSS tembiricha chiyero uye iyo SAEJ viscosity classification.

Maererano navo, mabhureki emvura anoratidzirwa nezvikamu zviviri zvikuru: kinematic viscosity uye poindi yekubikira.

Yekutanga inobata kugona kwemvura kutenderera mumitsetse pakushanda tembiricha kubva -40 ° kusvika +100 madhigirii.

Chechipiri - yekudzivirira kwemhute yekuvhara inoitika panguva yekuvira kweTJ uye kutungamirira kukundikana kwemabhureki.

Zvichienderana neizvi, viscosity yechero TF pa100°C inofanira kunge iri 1,5 mm²/s uye pa -40°C - isingapfuuri 1800 mm²/s.

Yese magadzirirwo akavakirwa pa glycol uye polyglycol yakanyanya hygroscopic, i. vanowanzotora hunyoro kubva kune zvakatipoteredza.

Kunyangwe mota yako ikasasiya nzvimbo yekupaka, hunyoro huchiri kupinda muhurongwa. Rangarira buri re "kufema" muvharo yetangi.

Mhando dzese dzeTJ dzine chepfu !!!

Zvinoenderana neiyo FMVSS standard, zvichienderana nehunyoro hwemukati, TJs dzakakamurwa kuita:

"Dry", mufekitari mamiriro uye isina unyoro.
"Yakanyoroveswa", yatora kusvika 3,5% yemvura panguva yebasa.

Zvinoenderana neDOT zviyero, iwo makuru marudzi eTA anosiyaniswa:

DOT 3. Mabhureki emvura anobva pane zviri nyore glycol compounds.

Kupisa kupisa,^оKubva:

"yakaoma" - kwete pasi pe205;
"yakanyoroveswa" - kwete pasi pe140.

Viscosity, mm²/pamwe:

"yakanyoroveswa" pa +100⁰C - kwete pasi pe1,5;
"yakanyoroveswa" pa -40⁰C - kwete kupfuura 1800.

Vanokurumidza kutora unyoro uye nekuda kweizvi, nzvimbo yekubikira yakaderera mushure menguva pfupi.

DOT 3 zvinwiwa zvinoshandiswa mumotokari dzine dhiramu mabhureki kana disc mabhureki pamavhiri epamberi.

Hupenyu hwesevhisi huri pasi pemakore maviri. Zvinwiwa zvekirasi iyi hazvidhure uye saka zvakakurumbira.

DOT 4. High performance polyglycol based. Izvo zvinowedzera zvinosanganisira boric acid, iyo inoderedza mvura yakawandisa.

Kupisa kupisa,^оKubva:

"yakaoma" - kwete pasi pe230;
"yakanyoroveswa" - kwete pasi pe150.

Viscosity, mm²/pamwe:

"yakanyoroveswa" pa +100⁰C - kwete pasi pe1,5;
"yakanyoroveswa" pa -40⁰C - kwete kupfuura 1500.

Mhando yakajairika yeTJ pamotokari dzemazuva ano dzine disc mabhureki "mudenderedzwa."

Yambiro. Yese glycols uye polyglycol yakavakirwa maTFs ane hukasha kune pendi.

DOT 5. Yakagadzirwa pahwaro hwesilicone. Hazvienderani nemamwe marudzi. Inosvika pa260^оC. Haizoparadze pendi kana kusveta mvura.

Pama serial mota, sekutonga, haina kushandiswa. TJ DOT 5 inoshandiswa mumhando dzakasiyana dzemotokari dzinoshanda pakupisa kwakanyanya.

DOT 5.1. Kubva pane glycols uye polyesters. Kubikira kwemvura "yakaoma" mvura 260^оC, "yakanyoroveswa" 180 madhigirii. Kinematic viscosity ndiyo yakaderera, 900 mm2/s pa -40^оC.

Inoshandiswa mumotokari dzemitambo, mota dzemhando yepamusoro uye midhudhudhu.

DOT 5.1/ABS. Yakagadzirirwa mota dzine anti-lock braking system. Yakagadzirwa pane yakasanganiswa nheyo ine glycols uye silicone ine pasuru ye anti-corrosion additives. Iine yakanaka lubricating properties, high boiling point. Iyo glycol mubhesi inoita iyi kirasi yeTJ hygroscopic, saka hupenyu hwavo hwesevhisi hunogumira makore maviri kusvika matatu.

Dzimwe nguva unogona kuwana mabhureki emvura epamba ane mazita ekuti DOT 4.5 uye DOT 4+. Hunhu hwemvura iyi huri mumirayiridzo, asi chiratidzo chakadaro hachipiwe nehurongwa hwepasi rose.

Paunosarudza brake fluid, unofanirwa kutungamirirwa nemirairo yemugadziri wemotokari.

Semuenzaniso, mune zvigadzirwa zvemazuva ano zveAvtoVAZ, zve "kutanga kuzadza", TJ brands DOT4, SAEJ 1703, FMSS 116 yemhando ROSDOT ("Tosol-Sintez", Dzerzhinsk) inoshandiswa.

Maintenance uye kutsiva brake fluid

Iyo brake fluid level iri nyore kudzora neiyo max uye min mamaki pamadziro ereservoir iri pane main brake cylinder.

Kana iyo TJ yakaderera, inofanira kuiswa kumusoro.

Vakawanda vanopikisa kuti chero mvura inogona kusanganiswa. Ichi hachisi chokwadi. MuDOT 3 class liquids, zvakakosha kuwedzera zvakafanana, kana DOT 4. Chero mimwe misanganiswa haina kukurudzirwa, uye neDOT 5 mvura inorambidzwa.

Matemu ekutsiva TJ anotemerwa nemugadziri uye anoratidzwa mumirayiridzo yekushandisa mota.

Iyo "kupona" kwezvinwiwa zvinoenderana neglycol uye polyglycol inosvika makore maviri kusvika matatu, iwo akachena silicone anogara kusvika gumi nemashanu.

Pakutanga, chero maTJs akajeka uye asina ruvara. Kusviba kwemvura, kurasikirwa kwekujeka, kutaridzika kwe sediment mune reservoir chiratidzo chechokwadi chekuti brake fluid inoda kutsiviwa.

Mune sevhisi yemotokari yakanyatsoshongedzerwa, dhigirii ye hydration ye brake fluid inozotemwa neakakosha mudziyo.
