Amamodeli amaningi wezimoto ze-MAZ afakwe i-clutch release actuator ene-pneumatic booster, indima ebalulekile ekusebenzeni kwayo edlalwa yi-actuator actuation valve.Funda konke mayelana nama-valve we-clutch actuator ye-MAZ, izinhlobo zawo kanye nemiklamo, kanye nokukhetha, ukushintshwa nokugcinwa kwalesi sihloko esihlokweni.
Iyini ivalvu ye-actuator ye-clutch ye-MAZ
I-MAZ clutch actuator actuator valve (i-clutch booster valve, KUS) iyivalvu yomoya ehlinzeka ngokuhlinzekwa nokopha komoya ocindezelwe ovela kusilinda somoya we-clutch booster lapho i-clutch ibanjiwe futhi inqanyulwa.
Amaloli we-MAZ wezinhlobo ezingu-500 zomndeni (kokubili ekuqaleni nakamuva 5335, 5549), i-MAZ-5336, 5337, 5551 yamanje, kanye ne-MAZ-5432, 6303 yamanje kanye nabanye ifakwe i-clutch double-plate, edinga kakhulu. umzamo.Ukulawula okuqondile kwe-clutch enjalo ukusuka ku-pedal kungaba isicefe kakhulu kumshayeli futhi kuzokhinyabeza kakhulu ikhono lokushayela imoto, ngakho-ke, iyunithi eyengeziwe yethulwa ku-clutch release drive (PVA) yalezi zinhlobo zamaloli - i-pneumatic booster. .
Ngokwesakhiwo, i-PVA ene-pneumatic booster iqukethe i-lever drive exhunywe ku-pedal, isilinda somoya kanye nengxenye ephakathi - i-KUS.I-cylinder igxiliwe kuhlaka lwemoto (ngobakaki), induku yayo ixhunywe nge-lever yezingalo ezimbili ku-clutch release fork roller.Induku ye-KUS ixhunywe kwenye ingalo ye-lever, futhi umzimba we-KUS uxhunywe ku-clutch pedal ngohlelo lwezinduku namalever ngokusebenzisa induku.
I-LCU iyingxenye yamandla yesigaxa se-PVA kanye nengxenye ebucayi yokulawula isilinda se-amplifier.Isiginali yokufaka ye-CRU indawo kanye nesiqondiso sokunyakaza kwe-clutch pedal: uma uyicindezela, i-LCU inikeza umoya ku-cylinder, iqinisekisa ukuthi i-amplifier ivuliwe (okungukuthi, ikhipha i-clutch), uma kukhishwa, i-LCU yopha umoya ovela kusilinda emkhathini, iqinisekisa ukuthi i-amplifier ivaliwe (okungukuthi, i-clutch ihileleke).Ngakho-ke, i-KUS iyingxenye ebalulekile yokusebenza kwe-clutch, uma ingasebenzi kahle, kuyadingeka ukuyilungisa noma ukuyishintsha ngokuphelele.Ukuze ulungise kahle, kuyadingeka ukuthola ulwazi oluyisisekelo mayelana nezinhlobo ezikhona zama-valve, ukwakheka kwazo nezinye izici.
Isakhiwo esijwayelekile kanye nomgomo wokusebenza kwamavalvu e-MAZ wokubandakanya i-clutch actuator
Kuzo zonke izimoto ze-MAZ, i-KUS efana ngokuyisisekelo isetshenziswa.Isisekelo sokuklama singumzimba we-cylindrical ohlanganiswe ezingxenyeni ezintathu eziphonsiwe - umzimba ngokwawo kanye nesembozo ezimbili zokugcina.Amakhava ngokuvamile anomklamo we-flange, anamathele emzimbeni ngezikulufu, ama-gaskets kumele asetshenziselwe ukuvala.Esembozweni sangaphambili secala, induku yobude obude ifakwe ngokuqinile, ekugcineni lapho kukhona imfoloko yokunamathisela ku-lever ye-clutch drive yezingalo ezimbili.
Umzimba uhlukaniswe waba imigodi emibili, ngayinye enemigudu ecushiwe yokuxhuma amapayipi.Emgodleni wangaphambili kukhona i-valve, endaweni evamile yentwasahlobo ecindezelwe esihlalweni sayo (endimeni yayo kukhola phakathi kwemigodi).Isiteshi esisemgodini wangaphambili siwukuhlinzeka - ngawo umoya ocindezelwe unikezwa i-valve kusuka kumamukeli ohambisanayo wesistimu ye-pneumatic yemoto.
Emkhakheni ongemuva wekesi kukhona induku engenalutho ephuma kukhava yangemuva, futhi iphethe imfoloko yokunamathisela ku-lever yezingalo ezimbili ye-clutch fork roller.Induku inomgodi oxhumana nomkhathi.Kusikwa intambo phezu kwenduku, lapho i-nati yokulungisa itholakala khona kanye ne-locknut yayo.Isiteshi esisemgodini ongemuva siyaphuma, i-hose inamathiselwe kuso, enikeza umoya ocindezelwe ku-cylinder ye-amplifier, kanye nokuphuma komoya ovela kusilinda ubuyela ku-KUS lapho kukhishwa i-pedal.
Ukusebenza kwe-KUS kanye ne-PVA yonke ene-pneumatic booster kulula kakhulu.Lapho i-clutch pedal ikhishwa, i-valve ivaliwe, ngakho-ke i-PVA ayisebenzi - i-clutch ihileleke.Lapho i-pedal icindezelwa, i-KUS, kanye nazo zonke ezinye izingxenye, ishintsha kuze kube yilapho igebe phakathi kwentongomane yokulungisa esiqwini kanye nesembozo sangemuva sezindlu sikhethiwe.Kulesi simo, isiqu sihlala ku-valve futhi siyiphakamise - ngenxa yalokho, umoya ovela emgodini ongaphambili we-valve ugeleza ungene emgodini ongemuva futhi ungene ku-clutch booster cylinder ngokusebenzisa ipayipi.Ngaphansi kwethonya lomoya ocindezelwe, i-cylinder piston iyashintsha futhi iqinisekise ukujikeleza kwe-clutch fork roller - iphakamisa ipuleti lokucindezela futhi ikhiphe i-clutch.Lapho i-pedal ikhishwa, lezi zinqubo ezingenhla zenzeka ngokulandelana okuphambene, i-valve iyavaleka futhi umoya ovela kusilinda se-amplifier ngokusebenzisa umgodi ongemuva we-KUS futhi imbobo yenduku yayo ingena emkhathini, amandla avela kumfoloko isusiwe futhi i-clutch iphinde ihileleke.
Idivayisi yokukhishwa kwe-Clutch ye-MAZ
Idizayini ye-MAZ clutch release booster valve
Ubukhulu be-valve kanye ne-cross-section yazo zonke izimbobo kukhethwa ukuze ukunikezwa komoya kusilinda se-PVA amplifier kwenziwe ngokushesha, futhi umoya uphumele emkhathini ngokuhlehlisa kancane.Lokhu kufeza ukubandakanyeka okushelelayo kwe-clutch kanye nokunciphisa izinga lokuguga lazo zonke izingxenye zokuhlikihla.
I-Nomenclature kanye nokusebenza kwamavalvu e-MAZ ukuze kusebenze i-clutch actuator
Kusetshenziswa amamodeli ambalwa ayisisekelo e-KUS emalolini e-MAZ:
- Ikati.inombolo 5335-1602741 - ye-MAZ-5336, 5337, 54323, 5434, 5516, 5551, 6303, 64255. Ihlinzekwa ngaphandle kwamapayipi, ukulungisa amantongomane namafoloko;
- Ikati.inombolo 5336-1602738 - ngoba MAZ-5336 futhi 5337 izimoto ukuguqulwa okuhlukahlukene.Inesiqu esifushanisiwe esingu-145 mm, ifika iphelele namapayipi;
- Ikati.inombolo 54323-1602738 - inenduku emfushane engu-80 mm, ifika iphelele ngamapayipi;
- Ikati.inombolo 5551-1602738 - ngoba MAZ-5337, 54323, 5551 izimoto.Inesiqu esingu-325 mm, ifika iphelele namapayipi;
- Ikati.Inombolo 63031-1602738 - inesiqu esingu-235 mm, ifika iphelele ngamapayipi.
Amavalvu ayahluka ngokwakhiwa kanye nobukhulu bomzimba, ubude beziqu/izinduku kanye nobude bamapayipi.Izingxenye zinikezwa emakethe ngokuhlelwa okuhlukahlukene - ngaphandle kwamapayipi kanye namapayipi, esimweni sesibili, amapayipi enjoloba anokuvikelwa ngendlela yesiphethu esontekile kanye nokufakwa okujwayelekile okuxhumayo namantongomane enyunyana asetshenziswa.
Izinkinga zokukhethwa, ukushintshwa kanye nokugcinwa kwe-valve ye-MAZ ukuze kufakwe i-clutch actuator
I-KUS iyunithi ye-pneumatic, ngaphezu kwalokho engaphansi kwemithwalo yemishini kanye nemiphumela yezici ezingezinhle zemvelo.Konke lokhu kuholela ekugqokeni kancane kancane kwe-valve futhi kungabangela ukukhubazeka okuhlukahlukene - ukulimala kwe-valve, ukuvuza komoya ngokusebenzisa izimpawu, ukuguqulwa kwenduku nenduku, ukulimala komzimba, "ukwehla" kwemithombo, njll.
Ukuze kushintshwe, kuyadingeka ukuthatha i-valve yohlobo olufanayo kanye nemodeli efakwe emotweni ngaphambili, noma kunconywa njenge-analogue eyamukelekayo ngumenzi.Lapha kufanele kukhunjulwe ukuthi ama-valve ezinhlobo ezihlukahlukene anezici ezihlukene nobukhulu, ngakho-ke ingxenye "engeyona yomdabu" ingase ingangeni nje kuphela, kodwa futhi ingaqinisekisi ukusebenza okuvamile kwe-clutch drive.
Uma uthenga i-valve, udinga futhi ukucabangela imishini yayo, uma kunesidingo, kungase kudingeke uthenge ama-hoses engeziwe, ama-plugs nama-fasteners.Ukuze ugweme izindleko ezingadingekile kanye nokulahlekelwa isikhathi, kuyadingeka ukuhlola ngokushesha isimo sezingxenye ku-drive, ama-fasteners nama-hoses.
Ukushintsha i-valve kufanele kwenziwe ngokuhambisana nemiyalelo yokulungisa imoto, kodwa ngokuvamile lokhu kusebenza kwehla ukuze kuvele kuhlakazwe ingxenye endala bese ufaka entsha, kuyilapho umoya kufanele uphume ohlelweni lwe-pneumatic.Khona-ke kuyadingeka ukulungisa i-valve usebenzisa i-nati esiqwini sayo - ibanga phakathi kwayo nesembozo sangemuva somzimba we-KUS kufanele sibe ngu-3.5±0.2 mm.Kamuva, konke ukugcinwa okujwayelekile kwe-valve kuncishiswa ekuhlolweni kwayo kwangaphandle kanye nokulungiswa kwemvume ecacisiwe.
Uma i-KUS ikhethiwe futhi ifakwe ngendlela efanele, khona-ke ukusebenza kwe-clutch drive yeloli ye-Minsk kuyoba okuthembekile nokuzethemba kunoma yiziphi izimo zokusebenza.
