Iimodeli ezininzi zeemoto ze-MAZ zixhotyiswe nge-clutch release actuator ene-pneumatic booster, indima ebalulekileyo ekusebenzeni kwayo edlalwa yi-actuator actuation valve.Funda konke malunga ne-MAZ clutch actuator valves, iintlobo zazo kunye noyilo, kunye nokukhetha, ukutshintshwa kunye nokugcinwa kwale nxalenye kwinqaku.
Yintoni ivalve ye-actuator ye-MAZ yeclutch
Ivalve ye-clutch actuator actuation ye-MAZ (ivalve ye-clutch booster, KUS) yivalve ye-pneumatic ebonelela ngobonelelo kunye nokopha komoya ocinezelweyo ukusuka kwi-cylinder ye-pneumatic ye-clutch booster xa i-clutch ibambene kwaye ikhutshwe.
Iilori ze-MAZ zeemodeli zeentsapho ezingama-500 (zombini kwangaphambili kwaye kamva 5335, 5549), i-MAZ-5336, 5337, 5551 yangoku, kunye ne-MAZ-5432, 6303 yangoku kunye nabanye baxhotyiswe nge-clutch ephindwe kabini, efuna kakhulu. umzamo.Ukulawulwa ngokuthe ngqo kwe-clutch enjalo ukusuka kwi-pedal kuya kuba nzima kakhulu kumqhubi kwaye kuya kuphazamisa kakhulu amandla okuqhuba imoto, ngoko ke, iyunithi eyongezelelweyo ifakwe kwi-clutch release drive (PVA) yale mifuziselo yelori - i-booster ye-pneumatic. .
Ngokwesakhiwo, i-PVA ene-booster ye-pneumatic iqukethe i-lever drive exhunywe kwi-pedal, i-cylinder ye-pneumatic kunye necandelo eliphakathi - i-KUS.I-cylinder igxininiswe kwisakhelo semoto (nge-bracket), intonga yayo ixhunyiwe nge-lever-arm lever kwi-clutch release fork roller.Intonga ye-KUS idibaniswe nengalo echaseneyo ye-lever, kwaye umzimba we-KUS uqhagamshelwe kwi-clutch pedal ngokusebenzisa inkqubo yeentonga kunye ne-levers ngokusebenzisa intonga.
I-LCU yomibini icandelo lamandla le-PVA ye-lever kunye necandelo elibucayi lolawulo lwe-cylinder ye-amplifier.Isibonakaliso segalelo le-CRU yindawo kunye nolwalathiso lokuhamba kwe-clutch pedal: xa uyicinezela, i-LCU inikezela umoya kwi-cylinder, iqinisekisa ukuba i-amplifier ivuliwe (oko kukuthi, ikhupha i-clutch), xa ikhutshwa, i-LCU yopha umoya kwi-cylinder ukuya emoyeni, iqinisekisa ukuba i-amplifier icinyiwe (oko kukuthi, i-clutch ibandakanyeka).Ngoko ke, i-KUS iyinxalenye ebalulekileyo yokusebenza kwe-clutch, ukuba ingasebenzi kakuhle, kuyimfuneko ukuyilungisa okanye ukuyibuyisela ngokupheleleyo.Ukwenza ukulungiswa ngokuchanekileyo, kuyimfuneko ukufumana ulwazi olusisiseko malunga neentlobo ezikhoyo zeevalve, isakhiwo sabo kunye nezinye iimpawu.
Ubume ngokubanzi kunye nomgaqo wokusebenza kweevalve ze-MAZ zokubandakanya i-clutch actuator
Kuzo zonke iimoto ze-MAZ, i-KUS efana ngokusisiseko kuyilo iyasetyenziswa.Isiseko soyilo ngumzimba we-cylindrical ohlanganiswe kwiindawo ezintathu zokuphonswa - umzimba ngokwawo kunye nezibophelelo ezimbini zokuphela.Izigqubuthelo zihlala zine-design ye-flange, zifakwe emzimbeni kunye nezikrufu, ii-gaskets kufuneka zisetyenziswe ukutywinwa.Kwisigubungelo sangaphambili secala, intonga yobude obongeziweyo ifakwe ngokungqongqo, ekupheleni kwayo kukho ifoloko yokudibanisa kwi-lever ye-clutch drive ephakathi kweengalo ezimbini.
Umzimba wohlulwe ube yimingxuma emibini, nganye inemibhobho edityanisiweyo yokuqhagamshela imibhobho.Kwi-cavity yangaphambili kukho i-valve, kwindawo eqhelekileyo yentwasahlobo icinezelwe kwisihlalo sayo (kwindima yayo ikhola phakathi kwemigodi).Umjelo okwindawo engaphambili ukubonelela - ngawo umoya ocinezelweyo unikezelwa kwivalve evela kummkeli ohambelana nenkqubo ye-pneumatic yemoto.
Kumqolo ongemva wecala kukho intonga engenanto ephuma kwisigqubuthelo sangasemva, kwaye ithwele ifolokhwe yokuncamathela kwi-lever yeengalo ezimbini ze-clutch fork roller.Intonga inomngxuma onxibelelana nomoya.Intambo inqunywe kwintonga, apho i-nut yokulungelelanisa ifumaneka kunye ne-locknut yayo.Umjelo kwindawo yangasemva ukukhutshwa, i-hose ifakwe kuyo, enika umoya oxinyiweyo kwi-cylinder ye-amplifier, kunye nokukhutshwa komoya ophuma kwi-cylinder ukubuyisela kwi-KUS xa i-pedal ikhutshwa.
Ukusebenza kwe-KUS kunye ne-PVA yonke ene-booster ye-pneumatic ilula kakhulu.Xa i-pedal ye-clutch ikhutshwe, i-valve ivaliwe, ngoko i-PVA ayisebenzi - i-clutch idibene.Xa i-pedal icinezelwe, i-KUS, kunye namanye amacandelo, ijika kude kube isithuba phakathi kwe-nut yokulungelelanisa kwi-stem kunye nekhava yangasemva yendlu ikhethiweyo.Kule meko, isiqu sihlala kwivalve kwaye siyiphakamise - ngenxa yoko, umoya ovela kumqolo ongaphambili wevalve uqukuqela ungene kumqolo ongasemva kwaye ungene kwi-clutch booster cylinder ngombhobho.Ngaphantsi kwempembelelo yomoya ocinezelweyo, i-cylinder piston iyatshintsha kwaye iqinisekise ukujikeleza kwe-clutch fork roller - iphakamisa iplate yoxinzelelo kwaye ikhuphe i-clutch.Xa i-pedal ikhululiwe, ezi nkqubo zingasentla zenzeka ngokulandelelana, ivalve iyavala kwaye umoya ovela kwi-cylinder ye-amplifier ngokusebenzisa umngxuma ongemva we-KUS kwaye umngxuma kwintonga yayo uphumele emoyeni, amandla avela kwifoloko. isusiwe kwaye i-clutch iphinda ibandakanyeke.
Isixhobo sokukhupha i-Clutch ye-MAZ
Uyilo lwe-MAZ clutch release booster valve
Imilinganiselo ye-valve kunye ne-cross-section yazo zonke izimbobo zikhethiweyo ukwenzela ukuba ukunikezelwa komoya kwi-cylinder ye-PVA amplifier kuqhutywe ngokukhawuleza, kwaye umoya uphuma emoyeni kunye nokunciphisa kancinci.Oku kuphumeza ukubandakanyeka okugudileyo kwe-clutch kunye nokunciphisa izinga lokunxiba kuzo zonke iindawo zokuhlikihla.
I-Nomenclature kunye nokusebenza kweevalvu ze-MAZ zokuvula i-clutch actuator
Iimodeli ezininzi ezisisiseko ze-KUS zisetyenziswa kwiilori ze-MAZ:
- Ikati.inombolo 5335-1602741 - ye-MAZ-5336, 5337, 54323, 5434, 5516, 5551, 6303, 64255. Ubonelelwa ngaphandle kwe-hoses, ukulungisa amantongomane kunye neefolokhwe;
- Ikati.inombolo 5336-1602738 - ye-MAZ-5336 kunye ne-5337 yezithuthi zokuguqulwa ezahlukeneyo.Inesiqu esifutshane se-145 mm, iza ngokupheleleyo kunye nemibhobho;
- Ikati.inombolo 54323-1602738 - inentonga emfutshane ye-80 mm, iza igcwele kunye ne-hoses;
- Ikati.inombolo 5551-1602738 - for MAZ-5337, 54323, 5551 izithuthi.Inesiqu esingama-325 mm, iza ngokupheleleyo kunye nemibhobho;
- Ikati.Inombolo ye-63031-1602738 - ine-stem ye-235 mm, iza ngokupheleleyo kunye ne-hoses.
Iivalvu ziyahluka kuyilo kunye nobukhulu bomzimba, ubude beziqu / iintonga kunye nobude bemibhobho.Amacandelo anikezelwa kwiimarike kwiindlela ezahlukeneyo zokucwangciswa - ngaphandle kwee-hoses kunye ne-hoses, kwimeko yesibini, i-hoses ye-rubber ekhuselweyo ngendlela yentwasahlobo ephothiweyo kunye nemigangatho yokudibanisa edibeneyo kunye namantongomane omanyano asetyenziswa.
Imiba yokukhetha, ukutshintshwa kunye nokugcinwa kwevalve ye-MAZ ukuze kufakwe i-clutch actuator
I-KUS iyunithi ye-pneumatic, eyongezelelweyo ixhomekeke kwimithwalo yemishini kunye nemiphumo yezinto ezimbi zokusingqongileyo.Konke oku kukhokelela ekugqokeni ngokuthe ngcembe kwevalve kwaye kunokubangela ukungasebenzi kakuhle - umonakalo kwivalve, ukuvuza komoya ngamatywina, ukuguqulwa kwentonga kunye nentonga, umonakalo emzimbeni, "ukuthotywa" kwemithombo, njl.
Ukutshintshwa, kuyimfuneko ukuthatha i-valve yohlobo olufanayo kunye nemodeli efakwe kwimoto ngaphambili, okanye icetyiswa njenge-analogue eyamkelekileyo ngumenzi.Apha kufuneka kukhunjulwe ukuba iivalve zeentlobo ezahlukeneyo zineempawu ezahlukeneyo kunye nobukhulu, ngoko ke inxalenye "engeyiyo inzalelwane" ayinakuwela nje kuphela, kodwa ayiqinisekisi ukusebenza okuqhelekileyo kwe-clutch drive.
Xa uthenga i-valve, kufuneka kwakhona uthathele ingqalelo izixhobo zayo, ukuba kuyimfuneko, unokufuna ukuthenga i-hoses eyongezelelweyo, iiplagi kunye ne-fasteners.Ukuze ugweme iindleko ezingeyomfuneko kunye nokulahlekelwa kwexesha, kuyimfuneko ukujonga ngokukhawuleza imeko yamacandelo kwi-drive, i-fasteners kunye ne-hoses.
Ukutshintshwa kwevalve kufuneka kuqhutywe ngokuhambelana nemiyalelo yokulungiswa kwemoto, kodwa ngokuqhelekileyo lo msebenzi uhla ngokukhawuleza ukukrazula inxalenye endala kunye nokufakela entsha, ngelixa umoya kufuneka uphume kwi-pneumatic system.Emva koko kuyimfuneko ukulungelelanisa i-valve usebenzisa i-nut kwisiqu sayo - umgama phakathi kwayo kunye nesigqubuthelo sangasemva somzimba we-KUS kufuneka ube yi-3.5±0.2 mm.Emva koko, konke ukugcinwa kwesiqhelo kwevalve kuncitshiswe ekuhlolweni kwayo kwangaphandle kunye nokulungelelaniswa kwemvume echaziweyo.
Ukuba i-KUS ikhethwe kwaye ifakwe ngokuchanekileyo, ngoko ukusebenza kwe-clutch drive yeloli yaseMinsk kuya kuthembeka kwaye kuqiniseke kuyo nayiphi na imeko yokusebenza.
