CCGT kugadzirisa pamotokari dzeMAZ

Iyo CCGT unit paMAZ yakagadzirirwa kuderedza simba rinodiwa kubvisa clutch. Michina iyi ine zvikamu zvekugadzira kwayo, pamwe nezvigadzirwa zveWabco zvinotengeswa kunze kwenyika. Somuenzaniso, PGU Vabko 9700514370 (ye MAZ 5516, 5336, 437041 (Zubrenok), 5551) kana PGU Volchansky AZ 11.1602410-40 (yakakodzera MAZ-5440). Nheyo yekushanda kwemidziyo yakafanana.

Mudziyo uye musimboti wekushanda

Pneumohydraulic amplifiers (PGU) inogadzirwa mukugadzirisa kwakasiyana-siyana, yakasiyana munzvimbo yemitsara uye dhizaini yebasa rekushanda uye casing inodzivirira.

Chimiro cheCCGT mudziyo unosanganisira zvinotevera zvikamu:

• hydraulic cylinder yakaiswa pasi pe clutch pedal, pamwe nepiston uye chitubu chekudzoka;
• chikamu chepneumatic, chinosanganisira piston, tsvimbo uye chitubu chekudzoka chakajairika kune pneumatics uye hydraulics;
• dhizaini yekudzora yakashongedzerwa diaphragm ine vharafu yekupedza uye chitubu chekudzoka;
• valve mechanism (inopinza uye yekubuda) ine hunde yakajairika uye elastic element yekudzosera zvikamu kunzvimbo isina kwayakarerekera;
• liner kupfeka chiratidzo tsvimbo.

Kubvisa mapeji mukugadzira kune zvitubu zvekumanikidza. Iko hakuna mapundu mukubatana neiyo clutch control fork, iyo inobvumidza iwe kudzora dhigirii rekupfeka kweiyo friction linings. Sezvo ukobvu hwezvinhu huchiderera, piston inonyura mukati meimba yeamplifier. Iyo piston inoshanda pane yakakosha chiratidzo chinozivisa mutyairi nezve yasara clutch hupenyu. Kutsiviwa kwedhisiki rinofambiswa kana mapadhi kunodiwa kana kureba kweprobe kunosvika 23 mm.

Iyo clutch booster yakashongedzerwa yakakodzera yekubatanidza kune yakajairwa pneumatic system yerori. Kushanda kwakajairika kweyuniti kunogoneka pakumanikidza mumhepo ducts inosvika 8 kgf/cm². Kune 4 maburi eM8 mabhaudhi ekubatanidza iyo CCGT kune rori furemu.

Mashandiro anoita mudziyo:

1. Paunodzvanya clutch pedal, simba rinoendeswa kune piston yehydraulic cylinder. Muchiitiko ichi, mutoro unoshandiswa kune boka repiston repusher.
2. Muteveri anobva atanga kushandura chinzvimbo chepiston mune pneumatic power unit. Iyo piston inoshanda pavharuvhu yekudzora yepusher, ichivhura iyo mhepo inopa kune gongo reiyo pneumatic cylinder.
3. Kumanikidza kwegasi kunoshandisa simba kune clutch control fork kuburikidza nedzinde rakasiyana. Iyo pushrod chain inogadzirisa kudzvanya zvichienderana nekuoma kwakaita tsoka yako pane clutch pedal.
4. Kana iyo pedal yaburitswa, kudzvanywa kwemvura kunoburitswa uye ipapo vheji yemhepo inovhara. Iyo piston yechikamu chepneumatic inodzokera kunzvimbo yayo yepakutanga.

Kukanganisa

CCGT kusashanda pamotokari dzeMAZ kunosanganisira:

1. Jamming yegungano nekuda kwekuzvimba kwechisimbiso chemaoko.
2. Kunonoka kupindurwa kweactuator nekuda kwemvura yakakora kana actuator pushrod piston inonamira.
3. Kuwedzera kuedza pamapedals. Chikonzero chekusashanda chinogona kunge chiri kukanganisa kwevhavha yemhepo yakamanikidzwa. Nekuputika kwakasimba kwezvinhu zvekuvhara, iyo pusher jams, iyo inokonzera kuderera kwekushanda kwechigadzirwa.
4. Clutch haina kubvisa zvachose. Iko kukanganisa kunoitika nekuda kwekusarongeka kwekutamba kwemahara.
5. Kuderera kwehuwandu hwemvura mutangi nekuda kwekutsemuka kana kuoma kwechisimbiso sleeve.

Обслуживание

Kuti iyo clutch system (imwe-disk kana kaviri-disk) yeMAZ rori ishande nemazvo, zvinodikanwa kuita kuchengetedza kwete chete kweiyo main mechanism, asiwo yeanobatsira - iyo pneumatic booster. Kugadziriswa kwesaiti kunosanganisira:

• chekutanga, iyo CCGT inofanirwa kuongororwa kukuvara kwekunze kunogona kukonzera kubuda kwemvura kana mweya;
• simbisa zvigadziriso zvose zvekugadzirisa;
• bvisa iyo condensate kubva kune pneumatic booster;
• iyo inofanirwawo kugadzirisa kusununguka kutamba kwepusher uye kusunungurwa kunotakura clutch;
• buritsa ropa iyo CCGT uye wowedzera brake fluid kune system reservoir kusvika padanho rinodiwa (usasanganise zvinwiwa zvemhando dzakasiyana).

Maitiro ekutsiva

Kutsiviwa kweCCGT MAZ kunopa kuiswa kwemahosi matsva nemitsetse. Manodhi ese anofanira kunge aine dhayamita yemukati inosvika 8 mm.

Iyo yekutsiva maitiro ine anotevera matanho:

1. Bvisa mitsara kubva pagungano rapfuura uye sunungura mapoinzi ekunamatira.
2. Bvisa gungano kubva mumotokari.
3. Isa iyo nyowani nyowani munzvimbo yayo yepakutanga, tsiva iyo yakakuvadzwa mitsetse.
4. Simbisa mapoinzi ekunamatira kune torque inodiwa. Zvipfeko zvakasakara kana kuti zvine ngura zvinokurudzirwa kutsiviwa nezvitsva.
5. Mushure mekuisa CCGT, zvakakosha kutarisa kukanganisa kwematanda ekushanda, izvo zvisingafaniri kudarika 3 mm.

Maitiro ekugadzirisa

Kugadzirisa kunoreva kushandura kutamba kwemahara kwe clutch yekuburitsa. Iyo gapu inotariswa nekufambisa forogo lever kure nespherical surface ye booster pusher nut. Kuvhiyiwa kunoitwa nemaoko, kuderedza kuedza, zvakakosha kuparadzanisa chitubu chelever. Kufamba kwakajairika 5 kusvika 6 mm (yakayerwa pamusoro pe90 mm radius). Kana iyo yakayerwa kukosha iri mukati me3 mm, inofanirwa kugadziriswa nekushandura bhora nut.

Mushure mekugadzirisa, zvinodiwa kuti utarise kuzara kwepusher, iyo inofanira kunge inenge 25 mm. Muedzo unoitwa nekudzvanya zvizere clutch pedal.

Pamitengo yakaderera, iyo booster haibvisi zvizere ma clutch discs.

Uyezve, kutamba kwemahara kwepedal kunogadziriswa, kunoenderana nekutanga kwekushanda kwe master cylinder. Kukosha kunoenderana nemukaha pakati pepiston uye pusher. Kufamba kwe6-12 mm, kuyerwa pakati pedhidhi, inoonekwa seyakajairika. Iyo clearance pakati pepiston uye pusher inogadziriswa nekushandura eccentric pini. Kugadziriswa kunoitwa ne clutch pedal yakaburitswa zvizere (kusvikira yasangana nerabha kumira). Pini inotenderera kusvika iyo yaunoda kutamba yemahara yasvika. Iyo nzungu inogadzirisa inobva yasimbiswa uye pini yeshear inoiswa.

Kupomba sei

Pane nzira mbiri dzekupomba zvakanaka CCGT. Yekutanga ine supercharger yekumba. CCGT kupomba paMAZ inoitwa sezvinotevera:

1. Gadzira mudziyo wekumanikidza wepamba kubva mubhodhoro repurasitiki rine huwandu hwe 0,5-1,0 litita. Makomba anoboorwa muvharo nepasi, umo mazamu ematoyi asina chubhu anozoiswa.
2. Kubva pane chikamu chakaiswa pasi pe tangi, inodiwa kubvisa spool valve.
3. Zadza bhodhoro neitsva brake fluid kusvika 60-70%. Vhara kuvhura kwevharuvhu paunenge uchizadza.
4. Batanidza mudziyo ne hose kune yakasungirirwa yakaiswa pane amplifier. A spoolless valve inoshandiswa pakubatanidza. Usati waisa mutsara, inodiwa kubvisa chinhu chekudzivirira uye kusunungura iyo yakakodzera nekuishandura 1-2 inotendeuka.
5. Ipa mweya wakamanikidzwa kune silinda kuburikidza nevharuvhu yakaiswa pane cap. Iyo gasi sosi inogona kuve compressor ine tire inflation pfuti. Iyo yekumanikidza geji yakaiswa muyuniti inobvumidza iwe kudzora kudzvanywa mutangi, iyo inofanirwa kunge iri mukati me3-4 kgf / cm².
6. Pasi pekuita kwemhepo, mvura inopinda mugomba reamplifier uye inobvisa mhepo mukati.
7. Maitiro acho anoenderera mberi kusvika anyangarika mabhuru emhepo mutangi yekuwedzera.
8. Mushure mekuzadza mitsara, zvakakosha kuomesa kusungirira uye kuunza chiyero chemvura mutangi kune inodiwa kukosha. Chiyero chiri 10-15 mm pazasi pemucheto wemitsipa yekuzadza chinoonekwa seyakajairika.

A reverse pumping method inobvumirwa, kana mvura iri pasi pekumanikidzwa ichipihwa kutangi. Kuzadza kunoenderera mberi kusvika pasisina gasi mabubbles abuda kubva pakukodzera (yaimbova isina kuvharwa ne 1-2 kutendeuka). Mushure mekuwedzera, valve inosimbiswa uye yakavharwa kubva kumusoro nerubber protective element.

Iwe unogona kuzvijaira iwe nenzira yechipiri zvakadzama nekuona vhidhiyo pazasi, uye iyo yekupomba mirairo iri nyore:

1. Sunungura dzinde uye uzadze tangi nemvura inoshanda.
2. Vhura vharafu uye mirira maminitsi gumi kusvika gumi nemashanu kuti mvura ibude negiravhiti. Tsiva bhaketi kana bheseni pasi pejeti.
3. Bvisa tsvimbo uye uisimbise zvakasimba kusvikira yamira. Fluid ichayerera ichibuda mugomba.
4. Pasina kusunungura tsinde, simbisa kukodzera.
5. Sunungura mudziyo kuti uidzorere panzvimbo yayo yepakutanga.
6. Zadza tangi nebrake fluid.

Mushure mekubuda ropa kweCCGT coupling, zvinokurudzirwa kutarisa mamiriro ekubatanidza tsvimbo, izvo zvisingafanirwe kukanganiswa. Uye zvakare, chinzvimbo cheiyo brake pad kupfeka sensor inotariswa, iyo tsvimbo haifanirwe kubuda kubva kune pneumatic cylinder muviri neanopfuura 23 mm.

Mushure meizvozvo, iwe unofanirwa kutarisa kushanda kweamplifier parori ine injini inomhanya. Kana paine kumanikidzwa mune pneumatic system yemotokari, zvinodikanwa kudzvinyirira pedal kusvika pakumira uye kutarisa kureruka kwekuchinja kwegiya. Magiya anofanirwa kushandura zviri nyore uye pasina ruzha rwekunze. Paunenge uchiisa bhokisi rine divider, inotarisirwa kutarisa kushanda kwechikwata chegungano. Muchiitiko chekushaya simba, nzvimbo yeruoko rwekutonga inofanira kugadziriswa.
