Mphamvu ya Hydraulic MAZ

Kusintha kwa chilolezo cha mgwirizano wa mpira wa hydraulic booster MAZ.

Maonekedwe a mipata pazikhomo za mpira amakhudza kwambiri masewero onse a headset. Nthawi zambiri, kusiyana kwa pini ya mpira 9 kumawonjezeka (onani mkuyu 94), kumene ndodo yotalikirapo imagwirizanitsidwa, popeza mphamvu zambiri zimafalitsidwa kudzera mu pini ya mpira kusiyana ndi pini ya mpira wa chiwongolero chowongolera.

Kuti musinthe mipata ya zikhomo za mpira, chowonjezera cha hydraulic chimaphwanyidwa pang'ono. Choncho, ndi bwino kuchita kusintha pa hydraulic booster kuchotsedwa galimoto.

Njira yokhazikitsira ili motere.

Kokani kusintha kwa gap:

• chotsani mapaipi;
• ikani chowonjezera cha hydraulic mu vise ndikumasula nati wa loko pa silinda;
• masulani thupi la hinge kuchokera pa silinda;
• konzani matupi a hinge mu vice, kumasula zotsekera zotsekera pa nati 7 (onani mkuyu 94);
• limbitsani nati 7 mpaka itayima, ndiye limbitsani loko wononga mwamphamvu;
• Sonkhanitsani thupi la mipira ndi silinda. Limbikitsani momwe zidzapitirire ndikumasula kumalo omwe amalola kuti mapaipi agwirizane.

Kusintha kophatikizana kwa pivot:

• konzani hydraulic booster mu vice;
• chotsani chivundikiro 12 kuchokera kwa wogawa, masulani ndi kuchotsa mtedza;
• masulani zomangira zokhala ndi koyilo ndikuchotsa nyumbayo pamodzi ndi koyilo;
• masulani zotsekera zotsekera 29;
• kulunga kapu 29 njira yonse ndikuitembenuza mpaka bowo la zotsekera ligwirizane ndi kapolo wapafupi wa chikho 36;
• limbitsani zotsekera zotsekera mpaka zitasiya;
• kukhazikitsa ndi kuteteza thupi koyilo;
• ikani spool mu manja a thupi, kuvala kapu 32, sungani nati kuti muyime, tsegulani ndi 1/12 kutembenuka ndikudula ulusi;
• kukhazikitsa ndi kuteteza chivundikiro 12 ndi mapaipi;
• kukhazikitsa hydraulic booster pagalimoto.

zotheka kulamulira malfunctions ndi njira kuthetsa iwo amaperekedwa pa khumi tabu.

MAZ hydraulic booster kukonza

Kuchotsa hydraulic booster m'galimoto. Kuti muchotse muyenera:

• kulumikiza kupanikizika ndi kukhetsa ma hoses kuchokera ku hydraulic booster;
• masulani nati wa bawuti yolumikizira mutagwira pini pamutu wa ndodo ya hydraulic servomotor, ndikugwetsa bawutiyo kuchokera m'bulaketi;
• kugunda pamutu wa ndodo ya hydraulic booster;
• masulani ndi kumasula mtedza woteteza hydraulic booster ku chowongoleredwa ndi mkono wotsatira;
• pogwiritsa ntchito nkhonya, kanikizani zala zanu kuchokera kumabowo a mkono wowongolera ndi ulalo wotsatira. Chotsani chowonjezera cha hydraulic. Njira yochotsera ma hydraulic booster ndi motere: chotsani mapaipi ndi zida;
• kumasula ulusi wolumikiza mutu wa tsinde ndi tsinde ndikumasula mutu. Chotsani chochapira chakunja; chivindikiro;
• pamene chitsamba cha rabara chatha, sungunulani mutu, womwe umamasula mtedza ndikusindikiza zitsulo zachitsulo, ndiyeno phula la rabara;
• chotsani chotchinga chogwira chivundikiro, chivundikiro ndi makina ochapira amkati kuchokera paphiri;
• masulani zomangira zomwe zikugwira chivundikiro cha silinda yowongolera, chotsani chochapira, chotsani mphete yosungira potsitsa chivundikiro cha silinda kumbuyo, chotsani chivundikirocho;
• chotsani pisitoni ndi ndodo ndikuyiphwanya;
• masulani nati wa loko wa silinda ndikutulutsa silinda;
• chotsani zingwe zomangirira zopangitsa za mpira ndi zotupa zokha;
• masulani zotsekera zotsekera, masulani nati yosinthira 7 (onani mkuyu 94), chotsani chopukusira 8, kasupe, crackers ndi pini ya mpira 9;
• masulani zomangira zomangira chivundikiro 12 ndikuchotsa chivundikirocho; masulani nati yomangira koyilo ndikuimasula, chotsani kapu 32;
• masulani zomangira zomwe zimagwira thupi la koyilo, tulutsani thupi, tulutsani koyilo;
• masulani zotsekera zotsekera, masulani pulagi 29, chotsani bawuti, chopondera 8, kasupe, ma crackers ndi pini 10;
• chotsani galasi 36;
• masulani kapu ya cheki valavu 35 ndikuchotsa kasupe wa mpira i.

Pambuyo pa disassembly, yang'anani mosamala mbali za hydraulic booster.

Zolemba ndi ma nick siziloledwa pamtunda wa spool, galasi la pini yowongolera ndi matupi awo. Malo othamangirapo pazitsulo za mpira ndi rocker ayenera kukhala opanda mano ndi kuvala mopitirira muyeso, ndipo mphete za mphira ziyenera kusonyeza kuwonongeka ndi kuwonongeka.

Ngati kuwonongeka kwapezeka, sinthani zigawozi ndi zatsopano.

Ikani chowonjezera cha hydraulic mu dongosolo lakumbuyo lakuchotsa. Pamaso msonkhano, akusisita pamalo a koyilo, galasi ndi zala; mafuta ndi woonda wosanjikiza wa lubricant ndi kuonetsetsa kuti koyilo ndi kapu kuyenda momasuka mu housings awo, popanda kusokonezedwa.

Sinthani chilolezo cholumikizira mpira monga tafotokozera pamwambapa.

Mukatha kusonkhana, thirirani mayendedwe a mpira ndi mafuta kudzera mu oiler 18.

Ikani chowonjezera cha hydraulic pagalimoto munjira yochotsamo.

Mukayika chowonjezera cha hydraulic, sungani mtedza woteteza mapini mwamphamvu ndikumapukuta mosamala.

Kukonzekera kwa hydraulic booster MAZ

Panthawi yogwira ntchito yagalimoto, yang'anani mwadongosolo kukhazikika kwa hydraulic booster ku bulaketi ya chimango chagalimoto, kumangirira kwa pulley ya hydraulic booster pump, nthawi ndi nthawi kumangitsa mtedza wa zida za mpira wogawa.

Yang'anani kuthamanga kwa lamba woyendetsa pampu pakukonza kulikonse. Kuthamanga kwa lamba kumasinthidwa ndi screw 15 (mkuyu 96, b). Ndi zovuta zolondola, kupatuka pakati pa lamba pansi pa mphamvu ya 4 kg kuyenera kukhala mkati mwa 10-15 mm. Mukakonza, tsekani wononga ndi nati 16.

Werenganinso 8350 ndi 9370 kukonza kalavani

Nthawi ndi nthawi, pa nthawi yomwe yasonyezedwa pa tchati chopaka mafuta, yang'anani kuchuluka kwa mafuta mu hydraulic booster pump reservoir, sinthani mafuta mu hydraulic booster system, ndikutsuka sefa yosungiramo madzi.

Tsiku ndi tsiku fufuzani kulimba kwa maulumikizidwe ndi zisindikizo za hydraulic booster, pampu, mapaipi ndi ma hoses a dongosolo.

Pachiwongolero cha mphamvu, gwiritsani ntchito mafuta oyera okha, osefedwa monga momwe zafotokozedwera pa tchati chopaka mafuta. Thirani mafuta mu mpope posungira 10-15 mamilimita m'munsimu chapamwamba m'mphepete mwa nkhokwe kudzera mu mphako ndi awiri mauna abwino. Mukathira mafuta, musagwedeze kapena kugwedeza mumtsuko.

Kugwiritsiridwa ntchito kwa mafuta oipitsidwa kumabweretsa kuvala kofulumira kwa silinda yowongolera mphamvu, magawo ogawa ndi mapampu.

Poyang'ana mlingo wa mafuta mu posungira posungira pa kukonza kulikonse (TO-1), mawilo akutsogolo a galimoto ayenera kuikidwa molunjika.

Pa TO-2 iliyonse, chotsani fyuluta mu thanki ndikutsuka. Ngati fyulutayo yatsekedwa kwambiri ndi ma depositi owumitsidwa, yambani ndi chochepetsera utoto wagalimoto. Musanachotse fyulutayo, yeretsani bwinobwino chivindikiro cha thanki ya zinyalala.

Mukamasintha mafuta, omwe amachitidwa 2 pa chaka (ndi kukonza nyengo), kwezani chitsulo chamoto kutsogolo kuti mawilo asakhudze pansi.

Kuti muchotse mafuta mu dongosolo, muyenera:

• tsegulani thanki ndipo, mutachotsa chivundikirocho, tsitsani mafuta;
• kulumikiza nozzles kuchokera kumaliseche ndi kukhetsa mapaipi a distribuerar ndi kukhetsa mafuta mpope kudzera mwa iwo;
• pang'onopang'ono kutembenuza flywheel kumanzere ndi kumanja mpaka itayima, tsitsani mafuta mu silinda yamphamvu.

Mukathira mafuta, yatsani chowongolera mphamvu:

• chotsani fyuluta mu thanki, yambani monga tafotokozera pamwambapa;
• yeretsani bwino thanki kuchokera mkati, kuchotsa zotsalira za mafuta oipitsidwa;
• khazikitsani fyuluta yotsuka mu thanki;
• Thirani mafuta atsopano mu thanki kudzera mumphaniyo wokhala ndi mauna awiri abwino ndikudikirira mpaka atuluke mu nozzles.

Mukadzaza mafuta atsopano, onetsetsani kuti mwachotsa mpweya ku dongosolo. Kwa ichi muyenera:

• onjezani mafuta ku thanki pamlingo womwe mukufuna ndipo musakhudze dongosolo kwa mphindi ziwiri;
• yambitsani injini ndikuilola kuti ipite mofulumira kwa mphindi ziwiri;
• Pang'onopang'ono tembenuzirani chiwongolero 2 nthawi zonse kupita kumanja ndi kumanzere mpaka mpweya utuluke pamalo osungiramo madzi. Ngati ndi kotheka, onjezerani mafuta pamlingo womwe uli pamwambapa; kubwezeretsanso chivundikiro cha thanki ndi zomangira zake;
• tembenuzirani mawilo kumanja ndi kumanzere, kuyang'ana ngati chiwongolero chili chosavuta komanso ngati mafuta akuchucha.

Yang'anani kuloledwa kwa zikhomo za mpira ndi injini yomwe ikuyenda pa TO-1 iliyonse, ndikutembenuza chiwongolero molunjika komanso mozungulira.

Sipayenera kukhala sewero pamgwirizano wa tayi. Mu hinge ya chiwongolero ndi injini kuyimitsidwa, sewero sayenera upambana 4 mm, ndi injini kuthamanga - mpaka 2 mm.
