Mitundu yambiri yamagalimoto a MAZ imakhala ndi chowongolera chotulutsa chowongolera ndi pneumatic booster, gawo lofunikira pakugwirira ntchito komwe kumaseweredwa ndi valavu ya actuator actuator.Phunzirani zonse za ma valve a MAZ clutch actuator, mitundu yawo ndi mapangidwe ake, komanso kusankha, kusintha ndi kukonza gawoli kuchokera m'nkhaniyi.
Kodi valavu ya MAZ clutch actuator actuator ndi chiyani?
The MAZ clutch actuator actuator valve (clutch booster valve, KUS) ndi valavu ya pneumatic yomwe imapereka mpweya wabwino komanso kukhetsa magazi kuchokera ku silinda ya pneumatic ya clutch booster pamene clutch ikugwira ntchito ndikuchotsedwa.
Magalimoto a MAZ a mitundu 500 ya banja (onse oyambirira komanso kenako 5335, 5549), MAZ-5336, 5337, 5551, ndi MAZ-5432, 6303 ndi ena omwe ali ndi zida ziwiri, zomwe zimafunika kwambiri. khama.Kuwongolera mwachindunji kwa clutch yotere kuchokera pa pedal kungakhale kotopetsa kwambiri kwa dalaivala ndipo kungasokoneze kwambiri kuyendetsa galimoto, chifukwa chake, gawo lowonjezera limalowetsedwa mu clutch release drive (PVA) yamagalimoto awa - chowonjezera pneumatic. .
Mwadongosolo, PVA yokhala ndi chowonjezera cha pneumatic imakhala ndi lever drive yolumikizidwa ndi pedal, silinda ya pneumatic ndi gawo lapakati - KUS.Silinda imakhazikika pa chimango chagalimoto (kupyolera mu bulaketi), ndodo yake imalumikizidwa kudzera pa lever ya manja awiri kupita ku clutch kumasula foloko.Ndodo ya KUS imalumikizidwa ndi mkono wotsutsana ndi lever, ndipo thupi la KUS limalumikizidwa ndi chopondapo cholumikizira kudzera munjira ya ndodo ndi ndodo pogwiritsa ntchito ndodo.
LCU ndi gawo lamphamvu la PVA la lever komanso gawo lodziwika bwino la amplifier cylinder control.Chizindikiro cholowera cha CRU ndi malo ndi njira yoyendetsera chopondapo cholumikizira: mukachikankhira, LCU imapereka mpweya ku silinda, kuwonetsetsa kuti amplifier imayatsidwa (ndiko kuti, imachotsa clutch), ikatero. imatulutsidwa, LCU imatulutsa mpweya kuchokera ku silinda kupita kumlengalenga, kuonetsetsa kuti amplifier yazimitsidwa (ndiko kuti, clutch ikugwira ntchito).Choncho, KUS ndi gawo lofunika kwambiri pa ntchito ya clutch, ngati itasokonekera, m'pofunika kukonzanso kapena kubwezeretsanso.Kuti mukonze bwino, ndikofunikira kudziwa zambiri zamitundu yomwe ilipo ya mavavu, kapangidwe kawo ndi zina.
Kapangidwe kake ndi mfundo yogwiritsira ntchito mavavu a MAZ potengera makina opangira clutch
Pamagalimoto onse a MAZ, KUS omwe ali ofanana pamapangidwe amagwiritsidwa ntchito.Maziko a mapangidwewo ndi thupi la cylindrical losonkhanitsidwa kuchokera ku zigawo zitatu zoponyedwa - thupi lokha ndi zophimba ziwiri.Zophimba nthawi zambiri zimakhala ndi mawonekedwe a flange, zimamangiriridwa ku thupi ndi zomangira, ma gaskets ayenera kugwiritsidwa ntchito kusindikiza.Pachivundikiro chakutsogolo cha mlanduwo, ndodo yotalikirapo imayikidwa mokhazikika, kumapeto kwake komwe kumakhala mphanda womangirira pa lever yapakatikati ya mikono iwiri clutch drive.
Thupi lagawidwa m'mabowo awiri, omwe ali ndi njira zolumikizira zolumikizira.Kutsogolo patsekeke pali valavu, mu malo yachibadwa kasupe mbamuikha mpando wake (mu udindo wake ndi kolala pakati pa mphanga).Njira yomwe ili kutsogolo ndikuperekera - kupyolera mu mpweya wopanikizika umaperekedwa ku valavu kuchokera kwa wolandila wofanana wa makina a pneumatic a galimoto.
Kumbuyo kwa khola pali ndodo yomwe imatuluka pachivundikiro chakumbuyo, ndikunyamula mphanda kuti imangirire ku lever ya mikono iwiri ya clutch foloko roller.Ndodoyo ili ndi kabowo komwe kamalumikizana ndi mlengalenga.Ulusi umadulidwa pa ndodo, pomwe mtedza wosinthira umakhala pamodzi ndi locknut yake.Njira yomwe ili kumbuyo kwake imatuluka, payipi imamangiriridwa pamenepo, yomwe imapereka mpweya woponderezedwa ku silinda ya amplifier, komanso kutuluka kwa mpweya kuchokera ku silinda kubwerera ku KUS pamene pedal imatulutsidwa.
Kugwira ntchito kwa KUS ndi PVA yonse yokhala ndi pneumatic booster ndikosavuta.Pamene chopondapo chowongolera chikutulutsidwa, valavu imatsekedwa, kotero PVA sichigwira ntchito - clutch ikugwira ntchito.Pamene pedal ikuphwanyidwa, KUS, pamodzi ndi zigawo zina zonse, zimasuntha mpaka kusiyana pakati pa mtedza wokonza pa tsinde ndi chivundikiro chakumbuyo cha nyumbacho chimasankhidwa.Pachifukwa ichi, tsinde limakhala pa valavu ndikulikweza - chifukwa chake, mpweya wochokera kutsogolo kwa valavu umalowa muzitsulo zam'mbuyo ndikulowa muzitsulo za clutch booster kudzera mu payipi.Mothandizidwa ndi mpweya woponderezedwa, pisitoni ya silinda imasuntha ndikuwonetsetsa kuzungulira kwa clutch foloko roller - imakweza mbale yokakamiza ndikuchotsa clutch.Pamene pedal imatulutsidwa, njira zomwe zili pamwambazi zimachitika motsatira dongosolo, valavu imatseka ndipo mpweya wochokera ku amplifier cylinder kudutsa kumbuyo kwa KUS ndipo phokoso la ndodo yake limalowa mumlengalenga, mphamvu yochokera ku foloko imatuluka. kuchotsedwa ndipo clutch ikugwiridwanso.

Mapangidwe a MAZ clutch release booster valve
Miyeso ya valavu ndi gawo lalikulu la mabowo onse amasankhidwa kuti mpweya wopita ku silinda ya PVA amplifier uchitike mofulumira, ndipo mpweya umalowetsedwa mumlengalenga ndikutsika pang'ono.Izi zimakwaniritsa kuyanjana kosalala kwa clutch ndikuchepetsa kuchuluka kwa kuvala kwa magawo onse akusisita.
Nomenclature ndi kugwiritsidwa ntchito kwa mavavu a MAZ poyambitsa clutch actiator
Mitundu ingapo yoyambira ya KUS imagwiritsidwa ntchito pamagalimoto a MAZ:
- Mphaka.nambala 5335-1602741 - kwa MAZ-5336, 5337, 54323, 5434, 5516, 5551, 6303, 64255. Amaperekedwa popanda hoses, kukonza mtedza ndi mafoloko;
- Mphaka.nambala 5336-1602738 - kwa MAZ-5336 ndi 5337 magalimoto zosintha zosiyanasiyana.Ili ndi tsinde lofupikitsidwa la 145 mm, limabwera ndi mapaipi;
- Mphaka.nambala 54323-1602738 - ili ndi ndodo yaifupi ya 80 mm, imabwera ndi hoses;
- Mphaka.nambala 5551-1602738 - kwa MAZ-5337, 54323, 5551 magalimoto.Ili ndi tsinde la 325 mm, imabwera ndi ma hoses;
- Mphaka.Nambala 63031-1602738 - ili ndi tsinde la 235 mm, imabwera ndi hoses.
Ma valve amasiyana ndi mapangidwe ndi miyeso ya thupi, kutalika kwa tsinde / ndodo ndi kutalika kwa payipi.Magawo amaperekedwa kumsika mumasinthidwe osiyanasiyana - opanda ma hoses ndi ma hoses, kachiwiri, ma hoses a rabara okhala ndi chitetezo ngati kasupe wopotoka komanso zolumikizira zokhazikika ndi mtedza wa mgwirizano zimagwiritsidwa ntchito.
Nkhani zakusankha, kusintha ndi kukonza valavu ya MAZ kuti ikhale ndi clutch actuator
KUS ndi gawo la pneumatic, lomwe limaphatikizidwanso ndi katundu wamakina komanso zotsatira za zinthu zoyipa zachilengedwe.Zonsezi zimayambitsa kuvala kwapang'onopang'ono kwa valavu ndipo zingayambitse zovuta zosiyanasiyana - kuwonongeka kwa valve, kutuluka kwa mpweya kupyolera mu zisindikizo, kusinthika kwa ndodo ndi ndodo, kuwonongeka kwa thupi, "kutsika" kwa akasupe, ndi zina zotero.
Kuti mulowe m'malo, m'pofunika kutenga valavu yamtundu womwewo ndi chitsanzo chomwe chinayikidwa pa galimoto kale, kapena tikulimbikitsidwa ngati analogue yovomerezeka ndi wopanga.Apa ziyenera kukumbukiridwa kuti ma valve amitundu yosiyanasiyana ali ndi mawonekedwe ndi miyeso yosiyana, kotero kuti gawo la "osakhala mbadwa" silingangogwera m'malo, komanso silingatsimikizire kuti kuyendetsa bwino kwa clutch drive.
Pogula valavu, muyenera kuganiziranso zipangizo zake, ngati n'koyenera, mungafunike kugula hoses zina, mapulagi ndi fasteners.Kupewa zosafunika ndalama ndi kutaya nthawi, m`pofunika yomweyo onani mmene mbali pa galimoto, fasteners ndi hoses.
Kusintha valavu kuyenera kuchitidwa motsatira malangizo okonzera galimoto, koma kawirikawiri opaleshoniyi imatsika ndikungochotsa gawo lakale ndikuyika latsopano, pamene mpweya uyenera kutuluka magazi kuchokera ku pneumatic system.Ndiye m'pofunika kusintha valavu pogwiritsa ntchito nati pa tsinde lake - mtunda pakati pa izo ndi kumbuyo chivundikiro cha KUS thupi ayenera kukhala 3.5 ± 0.2 mm.Pambuyo pake, kukonzanso kwachizoloŵezi kwa valve kumachepetsedwa kuti ayang'ane kunja ndi kusintha kwa chilolezo chodziwika.
Ngati KUS yasankhidwa ndikuyika molondola, ndiye kuti ntchito ya clutch drive ya galimoto ya Minsk idzakhala yodalirika komanso yodalirika pazochitika zilizonse.
