Incazelo kanye nezinhlobo ze-brake fluid

Isisekelo sesistimu ye-brake yemoto yi-volumetric hydraulic drive edlulisela ingcindezi kusilinda esiyinhloko kumasilinda asebenzayo wezinqubo zokubhuleka zamasondo.

Imishini eyengeziwe, ama-vacuum booster noma ama-hydraulic accumulators, akhulisa ngokuphindaphindiwe umzamo womshayeli ocindezela i-brake pedal, izilawuli zokucindezela nezinye izinto azizange ziguqule isimiso se-hydraulics.

I-master cylinder piston ikhipha uketshezi, okuphoqa ama-actuator pistons ukuthi anyakaze futhi acindezele amaphedi endaweni yama-brake discs noma izigubhu.

Isistimu ye-brake iyidrayivu ye-hydraulic eyodwa-acting, izingxenye zayo zihanjiswa endaweni yokuqala ngaphansi kwesenzo semithombo yokubuya.

Inhloso ye-brake fluid kanye nezidingo zayo

Inhloso icacile egameni - ukusebenza njengoketshezi olusebenzayo lwedrayivu ye-hydraulic yamabhuleki futhi uqinisekise ukusebenza kwawo okuthembekile ezinhlobonhlobo zamazinga okushisa nanoma yiziphi izimo zokusebenza.

Ngokwemithetho ye-physics, noma yikuphi ukungqubuzana ekugcineni kuphenduka ukushisa.

Amabhuleki amabhuleki, ashiswa ukungqubuzana ebusweni bediski (isigubhu), ashise izingxenye eziwazungezile, okuhlanganisa amasilinda asebenzayo kanye nokuqukethwe kwawo. Uma i-brake fluid ibilisa, umhwamuko wayo uzokhama ama-cuffs namasongo, futhi uketshezi luzokhishwa ohlelweni ngokucindezela okukhulu kakhulu. I-pedal ngaphansi konyawo lwesokudla izowela phansi, futhi kungase kungabi nesikhathi esanele sesibili "ipompo".

Enye inketho - eqhweni elinzima, i-viscosity ingakhula kangangokuthi ngisho ne-vacuum booster ngeke kusize i-pedal ukuthi iqhube "ibhuleki" eliqinisiwe.

Ngaphezu kwalokho, i-TJ kufanele ihlangabezane nalezi zimo ezilandelayo:

• Yiba nephuzu lokubilisa eliphezulu.
• Gcina ikhono lokupompa emazingeni okushisa aphansi.
• Ukuba ne-hygroscopicity ephansi, i.e. ikhono lokumunca umswakama ovela emoyeni.
• Iba nezindawo zokugcoba ukuvimbela ukuguga kwemishini kwezindawo zamaphistoni namasilinda ohlelo.

Ukuklanywa kwamapayipi esistimu yamabhuleki yesimanje kuqeda ukusetshenziswa kwanoma yimaphi ama-gaskets nama-seal. Amapayipi amabhuleki, ama-cuffs namaringi enziwe ngezinto zokwenziwa ezikhethekile ezimelana nezigaba ze-TJ ezinikezwe umenzi.

Qaphela! Izinto zokuvala izinsimbi azikwazi ukumelana nowoyela nophethiloli, ngakho-ke kwenqatshelwe ukusebenzisa uphethiloli nanoma yiziphi izincibilikisi ekushayeleni amasistimu amabhuleki noma izakhi zawo ngazinye. Sebenzisa i-brake fluid ehlanzekile kuphela kulokhu.

Brake uketshezi ukwakheka

Ezimotweni zekhulu leminyaka elidlule, i-mineral TJ yasetshenziswa (inhlanganisela yamafutha e-castor notshwala ngesilinganiso se-1: 1).

Ukusetshenziswa kwalezi zinhlanganisela ezimotweni zanamuhla akwamukeleki ngenxa ye-kinetic viscosity ephezulu (ukujiya ku--20 °) kanye nephuzu eliphansi lokubilisa (ngaphansi kuka-100 °).

Isisekelo se-TF yesimanje i-polyglycol (kufika ku-98%), i-silicone engavamile (kufika ku-93%) ngokungezwa kwezithasiselo ezithuthukisa izici zekhwalithi yesisekelo, ivikela ubuso bezindlela zokusebenza ekugqwaleni futhi ivimbele i-oxidation ye-oxidation. I-TF ngokwayo.

Kungenzeka ukuhlanganisa ama-TJ ahlukene kuphela uma enziwe ngendlela efanayo. Uma kungenjalo, ukwakheka kwama-emulsions okuphazamisa ukusebenza kungenzeka.

Ukuhlukaniswa

Ukuhlukaniswa kusekelwe kumazinga we-DOT wamazwe ngamazwe asekelwe ezingeni lokushisa le-FMVSS kanye nokuhlukaniswa kwe-viscosity ye-SAEJ.

Ngokuvumelana nabo, uketshezi lwamabhuleki lubonakala ngemingcele emibili eyinhloko: i-kinematic viscosity kanye nephuzu elibilayo.

Owokuqala unesibopho sokukwazi uketshezi ukujikeleza emigqeni emazingeni okushisa okusebenza kusuka ku--40 ° kuya ku-+100 degrees.

Okwesibili - ukuvimbela izingidi ze-vapor ezenzeka ngesikhathi sokubilisa kwe-TJ futhi kuholele ekuhlulekeni kwamabhuleki.

Ngokusekelwe kulokhu, i-viscosity yanoma iyiphi i-TF ku-100°C kufanele okungenani ibe ngu-1,5 mm²/s futhi ku- -40°C - ingabi ngaphezu kuka-1800 mm²/s.

Konke ukwakheka okusekelwe ku-glycol ne-polyglycol kune-hygroscopic kakhulu, i. kuvame ukumunca umswakama endaweni.

Ngisho noma imoto yakho ingashiyi indawo yokupaka, umswakama usangena ohlelweni. Khumbula imbobo "yokuphefumula" esivalweni sethangi.

Zonke izinhlobo ze-TJ zinobuthi!!!

Ngokwezinga le-FMVSS, kuye ngokuqukethwe komswakama, ama-TJs ahlukaniswe abe:

• "Yomile", esimweni sefekthri futhi ayiqukethe umswakama.
• "Oswakanyiswe", emunce amanzi afinyelela ku-3,5% ngesikhathi senkonzo.

Ngokwamazinga e-DOT, izinhlobo eziyinhloko ze-TA ziyahlukaniswa:

1. I-DOT 3. Ama-brake fluids asekelwe kuma-glycol compounds alula.

Izinga lokushisa elibilayo, ^оC:

• "eyomile" - hhayi ngaphansi kuka-205;
• "oswakanyiswe" - hhayi ngaphansi kuka-140.

I-viscosity, mm²/kanye:

• "oswakanyiswe" ngo +100⁰C - hhayi ngaphansi kuka-1,5;
• "oswakanyiswe" ngo -40⁰C - akukho ngaphezu kwe-1800.

Ngokushesha bamunca umswakama futhi ngenxa yalokhu, iphuzu lokubilisa liphansi ngemva kwesikhashana.

I-DOT 3 fluids isetshenziswa ezimotweni ezinamabhuleki ezigubhu noma ama-disc brakes emasondweni angaphambili.

Isilinganiso sempilo yesevisi ingaphansi kweminyaka emi-2. Uketshezi lwaleli klasi alubizi ngakho-ke luyathandwa.

2. I-DOT 4. Ngokusekelwe ekusebenzeni okuphezulu kwe-polyglycol. Izithasiselo zihlanganisa i-boric acid, eyenza amanzi amaningi angasebenzi.

Izinga lokushisa elibilayo, ^оC:

• "eyomile" - hhayi ngaphansi kuka-230;
• "oswakanyiswe" - hhayi ngaphansi kuka-150.

I-viscosity, mm²/kanye:

• "oswakanyiswe" ngo +100⁰C - hhayi ngaphansi kuka-1,5;
• "oswakanyiswe" ngo -40⁰C - akukho ngaphezu kwe-1500.

 

Uhlobo oluvame kakhulu lwe-TJ ezimotweni zanamuhla ezinamabhuleki e-disc "embuthanweni."

Isexwayiso. Wonke ama-glycols nama-TF asuselwa ku-polyglycol anolaka maqondana nomsebenzi wokupenda.

3. I-DOT 5. Ikhiqizwe ngesisekelo se-silicone. Akuhambisani nezinye izinhlobo. Kubilisa ngo-260 ^оC. Ngeke idle upende noma imunce amanzi.

Ezimotweni ze-serial, njengomthetho, ayisetshenziswa. I-TJ DOT 5 isetshenziswa ezinhlotsheni ezikhethekile zezimoto ezisebenza emazingeni okushisa aphezulu.

4. I-DOT 5.1. Ngokusekelwe kuma-glycols nama-polyester. Indawo yokubilisa ye-liquid "eyomile" engu-260 ^оC, "oswakanyiswe" 180 degrees. I-kinematic viscosity iphansi kakhulu, 900 mm2/s at -40 ^оC.

Isetshenziswa ezimotweni zezemidlalo, izimoto ezisezingeni eliphezulu nezithuthuthu.

5. I-DOT 5.1/ABS. Yakhelwe izimoto ezine-anti-lock braking system. Kwenziwe ngokuxubile okuqukethe i-glycols ne-silicone enephakheji yezithako zokulwa nokugqwala. Inezinto ezinhle zokugcoba, indawo yokubilisa ephezulu. I-glycol esisekelweni yenza lesi sigaba se-TF sibe ne-hygroscopic, ngakho-ke impilo yabo yesevisi ikhawulelwe eminyakeni emibili kuya kwemithathu.

Kwesinye isikhathi ungathola uketshezi lwamabhuleki lwasekhaya olunegama elithi DOT 4.5 kanye ne-DOT 4+. Izimpawu zalezi zinto eziwuketshezi ziqukethwe emiyalweni, kodwa ukumakwa okunjalo akuhlinzekwa yisistimu yamazwe ngamazwe.

Lapho ukhetha uketshezi lwamabhuleki, kufanele ulandele imiyalelo yomkhiqizi wemoto.

Isibonelo, emikhiqizweni yesimanje ye-AvtoVAZ, "yokugcwalisa kuqala", izinhlobo ze-TJ DOT4, SAEJ 1703, FMSS 116 zomkhiqizo we-ROSDOT zisetshenziswa ("Tosol-Synthesis", Dzerzhinsk) zisetshenziswa.

Ukugcinwa nokushintshwa kwe-brake fluid

Ileveli ye-brake fluid kulula ukuyilawula nge-max marks encane ezindongeni ze-reservoir etholakala kusilinda esikhulu sebhuleki.

Uma izinga le-TJ lehla, kufanele lifakwe phezulu.

Abaningi baphikisa ngokuthi noma yiluphi uketshezi lungaxutshwa. Lokhu akulona iqiniso. I-DOT 3 yekilasi le-TF kufanele igcwaliswe ngokufanayo, noma i-DOT 4. Noma yiziphi ezinye izingxube azinconywa, futhi zivinjelwe ngoketshezi lwe-DOT 5.

Imigomo yokushintsha i-TJ inqunywa umenzi futhi ikhonjiswe emiyalweni yokusebenza kwemoto.

"Ukusinda" koketshezi olusekelwe ku-glycol ne-polyglycol kufinyelela eminyakeni emibili kuya kwemithathu, ama-silicone kuphela ahlala kufika eshumini nanhlanu.

Ekuqaleni, noma yimaphi ama-TJ asobala futhi awanambala. Ukuba mnyama koketshezi, ukulahlekelwa obala, ukuvela kwenhlabathi echibini kuwuphawu oluqinisekile lokuthi uketshezi lwebhuleki ludinga ukushintshwa.

Enkonzweni yemoto ehlomele kahle, izinga le-hydration ye-brake fluid lizonqunywa idivayisi ekhethekile.

isiphetho

Isistimu yamabhuleki esebenzisekayo kwesinye isikhathi iyona kuphela into engakusindisa emiphumeleni engathandeki kakhulu.

Uma kungenzeka, qapha izinga loketshezi olusemabhulekini emoto yakho, luhlole kusenesikhathi bese ulushintsha uma kunesidingo.
