Zonse zokhudza vacuum brake booster VAZ 2107 - chipangizo, mfundo yogwiritsira ntchito ndikusintha nokha.

Vacuum booster ya VAZ 2107 brake system imatengedwa ngati gawo lodalirika, chifukwa sililephera. The malfunctions woyamba wa chinthu zimachitika pambuyo 150-200 makilomita zikwi. Pakachitika vuto, vutoli limathetsedwa m'njira ziwiri - kukonzanso kwathunthu kapena kukonza unit. Ataphunzira mapangidwe ndi mfundo ya ntchito ya amplifier, mwiniwake wa "zisanu ndi ziwiri" akhoza kugwiritsa ntchito njira zonse payekha.

Cholinga ndi malo a unit

Mitundu yoyambirira ya Zhiguli (VAZ 2101-2102), yopangidwa popanda amplifiers, idasiyanitsidwa ndi chopondapo "cholimba". Kuti aimitse galimotoyo mwadzidzidzi, woyendetsa galimotoyo anafunika kuyesetsa kwambiri. M'zaka za m'ma 70 m'zaka za m'ma XNUMXs, wopanga anayamba kukonzekeretsa magalimoto ndi vacuum boosters (chidule monga VUT), amene kwambiri kuonjezera mabuleki Mwachangu ndi kutsogolera ntchito dalaivala.

unit mu mawonekedwe a zitsulo "mbiya" waikidwa pa bulkhead pakati pa injini chipinda ndi kanyumba Vaz 2107, pa mpando woyendetsa. Zowonjezera za VUT:

• thupi ndi screwhead ku bulkhead ndi 4 M8 mtedza;
• kutsogolo kwa amplifier pa 2 M8 studs, silinda yaikulu ya brake imamangiriridwa;
• chopondereza cha chinthucho chimalowa mkati mwa chipinda chokwera anthu ndikulumikizana ndi lever ya brake pedal.

The vacuum booster of the brake system ili pakhoma la magawo omwe ali pakati pa chipinda chapaulendo ndi chipinda cha injini.

Ntchito ya chilimbikitso ndi kuthandiza dalaivala kukanikiza ndodo ya master brake silinda pogwiritsa ntchito vacuum force. Chotsiriziracho chimapangidwa pogwiritsa ntchito vacuum yotengedwa kuchokera ku injini kudzera pa chitoliro chapadera.

Chitsulo cha vacuum sampling chimalumikizidwa ndi njira yolowera kuchokera kumbali ya njira yopita ku silinda ya III. Mapeto achiwiri a chitoliro cha nthambi amagwirizanitsidwa ndi kuyenerera kwa valve yowunikira yomwe imayikidwa kunja kwa thupi la VUT.

Vacuum nthambi chitoliro VUT (kumanzere pa chithunzi) cholumikizidwa ndi koyenera pa zochulukira zochulukira.

Ndipotu, vacuum booster imagwira ntchito kwa dalaivala. Ndikokwanira kuti wotsirizirayo asindikize mopepuka pa pedal kuti galimoto iyambe kutsika.

Chipangizo ndi mfundo yogwiritsira ntchito VUT

Chowonjezera cha vacuum ndi "mbiya" yachitsulo yopangidwa ndi zigawo zotsatirazi (manambala omwe ali pamndandandawo akugwirizana ndi malo omwe ali pachithunzichi):

1. Cylindrical thupi.
2. The kuthamanga ndodo ya waukulu brake yamphamvu.
3. Chivundikiro cholumikizidwa ndi thupi ndi nsonga yopindika.
4. Pisitoni.
5. Cholowera vavu.
6. Brake pedal pusher.
7. Zosefera mpweya.
8. lowetsani buffer.
9. Chovala chapulasitiki chamkati.
10. mphira membrane.
11. Kasupe wobwereranso kwa mkati ndi nembanemba.
12. Kugwirizana kokwanira.
13. Onani valavu.
14. Vacuum chubu.
    

    Pakatikati pa amplifier amagawidwa ndi mphira diaphragm mu zipinda 2 ntchito

Chilembo "A" mu chithunzi chimasonyeza chipinda choperekera vacuum, zilembo "B" ndi "C" - njira zamkati, "D" - mlengalenga wolankhulana ndi mlengalenga. Tsinde pos. 2 imatsagana ndi gawo lokwerera la silinda yayikulu ya brake (yofupikitsidwa ngati GTZ), pusher pos. 6 yolumikizidwa ndi pedal.

Chipangizochi chimatha kugwira ntchito m'njira zitatu:

1. Galimoto imathamanga, koma dalaivala samamanga mabuleki. Kupuma kuchokera kwa osonkhanitsa kumaperekedwa kudzera muzitsulo "B" ndi "C" kuzipinda zonse ziwiri, valve imatsekedwa ndipo salola kuti mpweya wa mumlengalenga ulowe. Masimpe ngakuti ncikozyanyo cibotu kapati.
2. Mabuleki okhazikika. Chopondapo chimakhala chokhumudwa pang'ono, valavu imayamba mpweya (kupyolera mu fyuluta) mu chipinda cha "G", chifukwa chake mphamvu yopuma mu "A" imathandizira kukakamiza ndodo ya GTZ. Nyumba zapulasitiki zidzapita patsogolo ndikupumula motsutsana ndi pisitoni, kuyenda kwa ndodo kumayima.
3. Mabuleki mwadzidzidzi. Pamenepa, zotsatira za vacuum pa nembanemba ndi thupi si malire, ndodo ya silinda waukulu kufinyidwa kuti ayime.

Chifukwa cha kupsinjika kwa zipinda ziwirizi, nembanemba imathandiza kuyika mphamvu pa ndodo ya silinda.

Pambuyo pomasula pedal, kasupe amaponya thupi ndi nembanemba kubwerera kumalo awo oyambirira, valavu ya mumlengalenga imatseka. Valavu yosabwerera m'malo olowera m'mphuno imakhala ngati chitetezo ku jekeseni wadzidzidzi wa mpweya kuchokera kumbali zambiri.

Kupitilira kwa mpweya muzochulukira zomwe amadya ndikupitilira, kulowa mu brake booster, kumachitika pamainjini owonongeka kwambiri. Chifukwa chake ndi kutayika kwa valve yolowera kumpando wamutu wa silinda. Pa kukanikiza sitiroko, pisitoni imapanga kuthamanga kwa pafupifupi 7-8 atm ndikukankhira gawo la mpweya kubwerera muzobweza zambiri. Ngati valavu yoyang'ana sikugwira ntchito, idzalowa m'chipinda chopanda mpweya, kuchepetsa mphamvu ya VUT.

Zolakwika za Brake Booster

Popeza mphamvu ya brake imasinthidwa ndi vacuum, zovuta zambiri za VUT zimalumikizidwa ndi kutayika kwamphamvu:

• kuwonongeka kwa mphira diaphragm chifukwa cha kuvala kwambiri;
• mpweya m'mphepete mwa mlandu - pa mphambano pakati pa zivundikiro ziwiri;
• chimodzimodzi, kupyolera mu bokosi lodzaza pa ndodo ya GTZ;
• mavuto ndi payipi yoyamwa - ming'alu kapena kutayikira pamfundo.
  

  Vuto lachilendo la VUT ndi diaphragm yomwe imathyoka ndikulowetsa mpweya

Zochepa kwambiri ndizolephera kwa valve yodutsa mkati, kutsekeka kwa fyuluta ya mpweya ndi kuchepa kwa kasupe kuchokera kuvala kwachilengedwe. Nthawi zambiri, kasupe amasweka mu 2 mbali.

Mnzanga wina atakumana ndi chidwi - "zisanu ndi ziwiri" zidachepetsedwa mwamphamvu pambuyo poyambitsa injini. Kuwonongekaku kudayamba ndi kutenthedwa kosalekeza kwa ma brake discs ndi ng'oma pamawilo onse. Zinapezeka kuti kusweka kwa 2 kunachitika nthawi yomweyo mkati mwa vacuum booster - valavu idalephera ndipo masika obwerera adasweka. Poyesa kuyambitsa injini, VUT idangoyambitsidwa ndi vacuum, ndikufinya ndodo ya silinda yayikulu. Mwachilengedwe, ma brake pads onse adagwira - kunali kosatheka kusuntha galimotoyo.

Nthawi zina kutayikira kwamadzimadzi kumawonedwa pakati pa flange ya GTZ ndi vacuum booster. Koma vutoli silikhudza kuwonongeka kwa VUT, chifukwa madzi akutuluka mu silinda yayikulu. Chifukwa chake ndi kuvala ndi kutayika kwa zolimba za mphete zosindikizira (makapu) mkati mwa GTZ.

Kusaka zolakwika

Chizindikiro choyamba cha kutayika kwa kulimba kwa vacuum booster sikungowonongeka kwa mabuleki, monga momwe magwero ambiri pa intaneti amafotokozera kulephera kwake. Mpweya ukangoyamba kulowa mkati mwa nembanemba yotayikira, VUT imapitilira kugwira ntchito bwino, popeza injiniyo imakhala ndi nthawi yoti ikhale ndi vacuum m'chipinda cham'mbuyo. Chizindikiro choyamba ndi kusintha kwa ntchito ya injini yokha:

• chifukwa cha kutayikira mpweya mu yamphamvu yachitatu, injini akuyamba "kuthamanga" opanda ntchito;
• Kuthamanga kwa crankshaft "kuyandama", kuyamwa kwamphamvu, ndikokulirapo kwa matalikidwe a oscillation;
• injini yothamanga imakhudzidwa ndi chopondapo cha brake, masitepe akakanikizidwa mwamphamvu;
• kumawonjezera kumwa mafuta.

Kutuluka kwa mpweya mu injini kudzera mu VUT kumapangitsa kuti silinda yachitatu izimitsidwe - injini imayamba "kuthamanga"

Ngati woyendetsa galimoto amanyalanyaza zizindikiro zoyambirira, zinthu zimaipiraipira - chopondapo chimakhala cholimba ndipo chimafuna kuyesetsa kwambiri kuti muchepetse ndikuyimitsa galimoto. Galimotoyo imatha kuyendetsedwa mopitilira, kuwonongeka kwa VUT sikubweretsa kulephera kwathunthu kwa mabuleki, koma kumasokoneza kwambiri kukwera, makamaka ngati simunazolowere. Mabuleki angozi adzakhala vuto.

Momwe mungawonetsetse kuti vacuum booster ikutha:
