Konke mayelana ne-vacuum brake booster VAZ 2107 - idivayisi, isimiso sokusebenza kanye nokuzenzela wena

I-vacuum booster yesistimu ye-brake ye-VAZ 2107 ibhekwa njengeyunithi ethembekile, njengoba ihluleka kancane. Ukungasebenzi kahle kwesici sokuqala ngemuva kwamakhilomitha ayizinkulungwane eziyi-150-200. Uma kwenzeka ukungasebenzi kahle, inkinga ixazululwa ngezindlela ezimbili - ukushintshwa okuphelele noma ukulungiswa kweyunithi. Ngemva kokufunda ukuklama kanye nesimiso sokusebenza kwe-amplifier, umnikazi ohlakaniphile we "eziyisikhombisa" angakwazi ukusebenzisa kokubili izinketho eyedwa.

Inhloso kanye nendawo yeyunithi

Amamodeli okuqala e-Zhiguli (VAZ 2101-2102), akhiqizwa ngaphandle kwama-amplifiers, ahlukaniswa ne-brake pedal "eqinile". Ukuze amise imoto kungazelelwe, umshayeli kwadingeka enze umzamo omkhulu. Ngama-70s wekhulu elidlule, umenzi waqala ukuhlomisa izimoto nge-vacuum booster (efushanisiwe njenge-VUT), okwandisa kakhulu ukusebenza kahle kwe-braking futhi kube lula umsebenzi womshayeli.

Iyunithi ngesimo sensimbi "umgqomo" efakwe ku-bulkhead phakathi kwegumbi lenjini ne-VAZ 2107 cabin, kusukela esihlalweni somshayeli. Amaphoyinti okunamathiselwe e-VUT:

• umzimba uboshwe ku-bulkhead ngamantongomane angu-4 M8;
• phambi kwe-amplifier kuma-studs angu-2 M8, isilinda esiyinhloko se-brake sinamathiselwe;
• i-pressure pusher ye-elementi ingena ngaphakathi kwendawo yabagibeli bese ihlangana ne-brake pedal lever.

I-vacuum booster yesistimu ye-brake itholakala odongeni lokuhlukanisa phakathi kwendawo yabagibeli kanye negumbi lenjini.

Umsebenzi we-booster ukusiza umshayeli ukuthi acindezele induku ye-master brake cylinder esebenzisa i-vacuum force. Lesi sakamuva senziwa kusetshenziswa i-vacuum ethathwe enjinini ngepayipi elikhethekile.

Ipayipi lesampula le-vacuum lixhunywe endaweni eningi yokuthatha kusukela ohlangothini lwesiteshi esiholela kusilinda III. Ukuphela kwesibili kwepayipi yegatsha kuxhunywe ekufakweni kwe-valve yokuhlola efakwe ngaphandle komzimba we-VUT.

Ipayipi legatsha le-Vacuum VUT (ngakwesokunxele esithombeni) lixhunywe ku-fitting ku-multifold suction

Eqinisweni, i-vacuum booster yenza umsebenzi womzimba womshayeli. Kwanele ukuthi laba bamuva bacindezele kancane ku-pedal ukuze imoto iqale ukwehla.

Idivayisi kanye nesimiso sokusebenza VUT

I-vacuum booster "umgqomo" wensimbi ohlanganisa izingxenye ezilandelayo (izinombolo ezisohlwini zihambisana nezindawo ezisemdwebeni):

1. Umzimba we-cylindrical.
2. I-pressure rod yesilinda esikhulu sebhuleki.
3. Ikhava exhunywe emzimbeni ngokugoqa ngephoyinti.
4. Piston.
5. I-Bypass valve.
6. I-brake pedal pusher.
7. Isihlungi somoya.
8. Faka isigcinalwazi.
9. Isikhwama sepulasitiki sangaphakathi.
10. ulwelwesi lwenjoloba.
11. Intwasahlobo yokubuya kwekesi langaphakathi ngolwelwesi.
12. Ukuhlanganisa ukulinganisa.
13. Hlola i-valve.
14. Vacuum tube.
    

    I-cavity yangaphakathi ye-amplifier ihlukaniswe nge-diaphragm yerabha ibe amakamelo okusebenza angu-2

Incwadi ethi "A" emdwebeni ikhombisa igumbi lokuhlinzeka nge-vacuum, izinhlamvu "B" no "C" - iziteshi zangaphakathi, "D" - imbobo exhumana nomoya. Isiqu pos. 2 incike engxenyeni yokukhwelana yesilinda esikhulu sebhuleki (efushanisiwe njenge-GTZ), i-pusher pos. 6 enamathiselwe ku-pedal.

Iyunithi iyakwazi ukusebenza ngezindlela ezi-3:

1. Injini iyagijima, kodwa umshayeli akawabambeli amabhuleki. I-vacuum evela kumqoqi inikezwa ngamashaneli "B" no "C" kuwo womabili amakamelo, i-valve ivaliwe futhi ayivumeli umoya womoya ukuba ungene. Intwasahlobo ibamba i-diaphragm endaweni yayo yokuqala.
2. Ukubhuleka njalo. I-pedal icindezelekile kancane, i-valve iqala umoya (ngesihlungi) ekamelweni elithi "G", yingakho amandla e-vacuum ku-cavity "A" asiza ukufaka ingcindezi kunduku ye-GTZ. Izindlu zepulasitiki zizoqhubekela phambili futhi ziphumule ngokumelene ne-piston, ukunyakaza kwenduku kuzoyeka.
3. Ukubhuleka okuphuthumayo. Kulokhu, umphumela we-vacuum ku-membrane nomzimba awunqunyelwe, induku yesilinda eyinhloko igxiliwe ukuze ime.

Ngenxa yomehluko wengcindezi emakamelweni amabili, ulwelwesi lusiza ukufaka ingcindezi ku-master cylinder rod.

Ngemva kokukhulula i-pedal, intwasahlobo iphonsa umzimba kanye nolwelwesi endaweni yalo yasekuqaleni, i-valve yasemkhathini iyavala. I-valve engabuyi endaweni yokufaka umlomo wombhobho isebenza njengesivikelo ekujovweni komoya kungazelelwe ukusuka ohlangothini oluningi.

Ukugqashuka kwamagesi ku-multifold intake futhi kuqhubeke, ku-booster yamabhuleki, kwenzeka ezinjinini eziguge kakhulu. Isizathu ukulingana okuxekethile kwe-valve yokungena esihlalweni sekhanda lesilinda. Ku-compress stroke, i-piston idala ukucindezela okungaba ngu-7-8 atm futhi iphushe ingxenye yamagesi ibuyele ku-manifold. Uma i-valve yokuhlola ingasebenzi, izongena ekamelweni le-vacuum, inciphise ukusebenza kahle kwe-VUT.

Amaphutha e-Brake Booster

Njengoba i-brake force ithathelwa indawo yi-vacuum, ukungasebenzi kahle kwe-VUT kuhlotshaniswa nokulahlekelwa kokuqina:

• ukuphulwa kwe-diaphragm yerabha ngenxa yokugqoka okubucayi;
• ukungena komoya onqenqemeni lwecala - lapho kuhlangana khona izembozo ezimbili;
• okufanayo, ngokusebenzisa ibhokisi lokugxusha phezu kwenduku ye-GTZ;
• izinkinga ngepayipi lokumunca - ukuqhekeka noma ukuvuza emalungeni.
  

  Ukungasebenzi kahle kwe-VUT i-diaphragm egugile ephuka futhi idedele umoya

Okungavamile kakhulu ukwehluleka kwe-valve ye-bypass yangaphakathi, ukuvala isihlungi somoya kanye nokuncipha kwentwasahlobo kusuka ekugqokeni kwemvelo. Ezimweni ezingavamile kakhulu, intwasahlobo ihlukana ibe izingxenye ezi-2.

Lapho umngane wami ehlangana nomphumela othakazelisayo - "eziyisikhombisa" zehliswa ngokuqinile ngemva kokuqala injini. Ukungasebenzi kahle kwandulelwe ukushisisa okungapheli kwama-brake discs nezigubhu kuwo wonke amasondo. Kwavela ukuthi ukuphuka kwe-2 kwenzeka ngokushesha ngaphakathi kwe-vacuum booster - i-valve yehlulekile futhi intwasahlobo yokubuya yaphuka. Lapho uzama ukuqalisa injini, i-VUT yavuswa ngokuzenzakalelayo i-vacuum, ngokuzenzakalelayo incindezela induku yesilinda esikhulu. Ngokwemvelo, wonke ama-brake pads abanjwe - kwakungenakwenzeka ukuhambisa imoto.

Kwesinye isikhathi ukuvuza kwe-brake fluid kubonwa phakathi kwe-flange ye-GTZ ne-vacuum booster. Kodwa le nkinga ayisebenzi ekuqhekekeni kwe-VUT, ngoba uketshezi luyavuza kusilinda esikhulu. Isizathu ukuguga nokulahlekelwa ukucinana kwezindandatho zokuvala (cuffs) ngaphakathi kwe-GTZ.

I-phlegm ezungeze i-flange ekhuphukayo ibonisa ukuvuza kwe-brake fluid evela ku-GTZ

Ukuxazulula inkinga

Uphawu lokuqala lokulahlekelwa ukuqina kwe-vacuum booster akukhona neze ukuwohloka kwamabhuleki, njengoba imithombo eminingi ye-inthanethi ichaza ukungasebenzi kahle. Lapho umoya uqala ukungena kulwelwesi oluvuzayo, i-VUT iyaqhubeka nokusebenza kahle, njengoba injini inesikhathi sokugcina i-vacuum ekamelweni elingaphambili. Uphawu lokuqala izinguquko ekusebenzeni kwenjini ngokwayo:

• ngenxa yokuvuza komoya ku-cylinder yesithathu, injini iqala "ukuhamba" ngokungenzi lutho;
• ijubane le-crankshaft “lintanta”, lapho ukuncela kunamandla, kuyanda nokuphakama kwama-oscillations;
• injini egijimayo isabela ku-pedal yebhuleki, izitebele lapho icindezelwe kakhulu;
• ukusetshenziswa kukaphethiloli kuyanda.

Ukuvuza komoya enjinini nge-VUT kubangela ukucisha isilinda yesithathu - injini iqala "ukuhamba"

Uma umshayeli engazinaki izimpawu eziyinhloko, isimo siba sibi kakhulu - i-pedal iba nzima futhi idinga umzamo owengeziwe womzimba ukunciphisa nokumisa imoto. Imoto ingasebenza ngokuqhubekayo, ukuwohloka kwe-VUT akuholeli ekuhlulekeni okuphelele kwamabhuleki, kodwa kuyinkimbinkimbi kakhulu yokugibela, ikakhulukazi uma ungayijwayele. I-Emergency braking izoba yinkinga.

Ungaqiniseka kanjani ukuthi i-vacuum booster iyavuza:

1. Khulula i-clamp bese ususa ishubhu ye-vacuum ekufakeni ku-manifold.
2. Xhuma okokufaka ngepulaki yasekhaya eqinile.
3. Qala injini. Uma i-revs iphuma ngaphandle, inkinga isobala ku-amplifier.
4. Susa intambo kagesi ephezulu bese uvala ipulaki ye-spark yesilinda III. Uma i-VUT ihluleka, ama-electrode azobhenywa ngomsizi omnyama.
   

   Uma umsizi ubonwa ku-spark plug ye-cylinder III, futhi amanye ama-spark plugs ahlanzekile, udinga ukuhlola isimo se-vacuum brake booster.

Noma nini lapho kungenzeka, ngisebenzisa indlela endala ethi "umkhulu" - ngimane ngincinze ipayipi lokukhetha i-vacuum ngodlawu ngenkathi injini isebenza. Uma i-cylinder yesithathu ifakiwe emsebenzini futhi idling ibuyiselwe, ngiqhubeka ngihlola i-booster ye-brake.

Ngokufanayo, inkinga ingalungiswa okwesikhashana kwezokuthutha. Nqamula ipayipi, xhuma i-fitting bese uhamba ngokuthula egalaji noma esiteshini sesevisi - iyunithi yamandla izosebenza kahle, ngaphandle kokusetshenziswa kukaphethiloli ngokweqile. Kodwa khumbula, i-pedal yebhuleki izoqina futhi iyeke ukuphendula ngokushesha ekucindezelweni okuncane.

Izindlela zokuxilonga ezengeziwe:

1. Cindezela ibhuleki izikhathi ezi-3-4 bese uqala injini ngenkathi ubambe i-pedal. Uma ingazange ihluleke, i-valve kufanele ihlulekile.
2. Uma injini icishiwe, nqamula ipayipi endaweni efakelwe, khipha ivalve yokuhlola bese ufaka ngokuqinile isibani senjoloba esicindezelwe ngaphambili embobeni. Ku-amplifier evaliwe, izogcina isimo sayo, kwelinye elinephutha, izogcwala umoya.
   

   Ukuze uhlole ukuqina kwe-amplifier nokusebenza kwe-valve yokuhlola, ungasebenzisa isibani senjoloba

Ngosizo lwepheya, ungakwazi ukucacisa ngokunembile indawo yesici, kodwa i-vacuum booster kuzodingeka isuswe. Lapho uphonsa umoya ekamelweni, geza imiphetho yamalunga kanye ne-stem seal - ama-bubbles azobonisa indawo yomonakalo.

Ividiyo: indlela yokuhlola i-vacuum brake booster ku-"seven"

Ungahlola kanjani i-vacuum brake booster.

Imiyalo yokufaka esikhundleni

Ezimweni eziningi, abanikazi be-"sevens" bashintsha umhlangano we-vacuum amplifier, ngoba ukulungiswa kweyunithi akunikezi umphumela omuhle ngaso sonke isikhathi. Isizathu esiyinhloko siwubunzima bokuhlangana, noma kunalokho, ukubuyiselwa kwe-hermetic factory rolling yecala.

Ukushintshwa akudingi izimo ezikhethekile namadivayisi akhethekile; umsebenzi wenziwa egaraji noma endaweni evulekile. Amathuluzi asetshenzisiwe:

• isethi yamakhanda anesandiso kanye ne-ratchet;
• ubukhulu be-spanner wrench 13 mm;
• i-wrench evulekile 7 mm kanye ne-caliper ene-gauge yokujula yokulungiswa;
• screwdriver flat kanye "phillips";
• impintshisi.
  

  Ngosizo lwe-caliper - "columbine" kulula kakhulu ukulungisa i-stem overhang ku-booster entsha ye-brake.

Kanye ne-booster ye-brake, kufanelekile ukushintsha i-vacuum hose nama-clamps - izingxenye ezindala zingabangela ukuvuza komoya.

I-VUT ishintshwa ngendlela elandelayo:

1. Khulula i-clamp bese unqamula i-vacuum hose endaweni yokuhlola ivalvu.
   

   Ishubhu levacuum lingakhishwa kanye nevalve engabuyi ngokuphenya ngobumnene ngesikulufu esiyisicaba
2. Usebenzisa isokhethi engu-13 mm nesikrini esinesandiso, khulula amantongomane uvikele isilinda esiyinhloko sebhuleki.
   

   Kungcono kakhulu ukukhulula amantongomane okulungisa ngekhanda kukhola ende
3. Khipha ngokucophelela i-GTZ kuma-studs bese uye eceleni njengoba amapayipi amabhuleki evuma.
   

   Akudingekile ukukhulula futhi unqamule amapayipi ama-brake, kwanele ukususa i-GTZ kusuka ku-studs bese uyihambisa eceleni.
4. Iya endaweni yabagibeli futhi ufinyelele mahhala kumantongomane angu-4 avikela iyunithi. Ukuze wenze lokhu, qaqa i-trim yokuhlobisa ephansi yekholomu yokuqondisa (ebanjwe ngezikulufo ezi-4).
5. Nqamula ingalo yokunyathela ku-pushrod ngokukhipha isiyingi nephinikhodi yensimbi.
6. Usebenzisa isipanela esingu-13 mm, qaqa amantongomane okulungisa bese ukhipha i-vacuum booster eceleni kwekhompathimenti yenjini.
   

   Umzimba weyunithi usongwe ohlangothini lwekhompathi yabagibeli ngamantongomane angu-4, aphezulu angu-2 afihlwe ngaphansi kwesikhumba.

Ukuhlanganisa kwenziwa ngendlela efanayo, kuphela ngokulandelana okuphambene. Ngaphambi kokufaka i-VUT entsha, qiniseka ukuthi ulungisa ubude bengxenye ephumayo yenduku ukuze unikeze i-pedal yebhuleki ngokudlala okuncane kwamahhala. Ukulungiswa kwenziwa kanjani:

1. Khipha okokufaka kwebhafa yepulasitiki ukusuka ohlangothini lweflange ye-GTZ, shonisa isiqu siye esitobhini.
2. Usebenzisa i-deep gauge (noma enye idivayisi yokulinganisa), kala ubude bekhanda lesiqu eliphuma endizeni yomzimba. Ububanzi obuvunyelwe - 1 ... 1,5 mm.
   

   Isilinganiso senziwa ngesiqu esihlehlisiwe; ukuze kube lula, kusetshenziswa i-caliper enerula
3. Uma isiqu siphuma ngaphansi noma ngaphezulu kwemingcele ecacisiwe, bamba ngokucophelela induku nge-pliers futhi ulungise ukufinyelela ngokuguqula ikhanda nge-wrench engu-7 mm.
   

   Induku ingalungiswa ngqo emotweni ngemuva kokufaka i-VUT

Futhi, ngaphambi kokufakwa, kunconywa ukuphatha izakhi zenjoloba ngamafutha angenalutho angenalutho - lokhu kuzokwandisa impilo yeyunithi.
