Mhando dzakawanda dzemotokari dzeMAZ dzakashongedzerwa neclutch release actuator ine pneumatic booster, basa rakakosha mukushanda kwaro rinoitwa neactuator actuation valve.Dzidza zvese nezve MAZ clutch actuator mavharuvhu, marudzi avo uye magadzirirwo, pamwe nekusarudzwa, kutsiva uye kugadzirisa kwechikamu ichi kubva kuchinyorwa.
Chii chinonzi MAZ clutch actuator actuator valve
Iyo MAZ clutch actuator actuation valve (clutch booster valve, KUS) ivharuvhu yepneumatic inopa kupa uye kubuda ropa kwemweya wakadzvanywa kubva kupneumatic cylinder ye clutch booster kana clutch yabatikana uye yakabviswa.
MAZ marori emhando mazana mashanu emhuri (zvekutanga uye gare gare 5335, 5549), yemazuva ano MAZ-5336, 5337, 5551, uye yazvino MAZ-5432, 6303 uye vamwe vakashongedzerwa nekaviri-plate clutch, iyo inoda hukuru. kuedza.Kudzora kwakananga kweclutch yakadai kubva pachitsika kungave kunetesa kumutyairi uye kwaizokanganisa zvakanyanya kugona kutyaira mota, saka, imwe yekuwedzera unit inounzwa mu clutch kuburitsa drive (PVA) yeaya mamodheru emarori - pneumatic booster. .
Zvimiro, PVA ine pneumatic booster ine lever drive yakabatana kune pedal, pneumatic cylinder uye yepakati chikamu - iyo KUS.Iyo cylinder inogadziriswa pamhando yemotokari (kuburikidza nebhurakiti), tsvimbo yayo yakabatanidzwa kuburikidza nemaoko maviri-lever kune clutch release fork roller.Iyo KUS tsvimbo yakabatana kune yakatarisana ruoko rwerevheti, uye iyo KUS mutumbi wakabatana kune clutch pedal kuburikidza nehurongwa hwematanda uye marevhisi nenzira yetsvimbo.
Iyo LCU ndiyo yese chikamu chesimba chePVA lever uye chinonzwisiswa chikamu cheamplifier cylinder control.Chiratidzo chekupinza cheCRU inzvimbo uye kutungamira kwekufamba kwe clutch pedal: kana iwe uchiidzvanya, iyo LCU inopa mweya kune silinda, ichiva nechokwadi chekuti amplifier yakabatidzwa (kureva, inobvisa clutch), kana yavepo. inoburitswa, iyo LCU inoburitsa mhepo kubva muhumburumbira ichienda mumhepo, ichiva nechokwadi chekuti amplifier yakadzimwa (kureva kuti, clutch inobatwa).Naizvozvo, iyo KUS chikamu chakakosha chekushanda kweclutch, kana ikasashanda, inofanirwa kugadzirisa kana kuitsiva zvachose.Kuti ugadzirise nenzira kwayo, zvinodikanwa kuwana ruzivo rwekutanga pamusoro pemhando dziripo dzevhavha, chimiro chavo uye zvimwe zvinhu.
Iyo yakajairika chimiro uye musimboti wekushanda kweMAZ mavharuvhu ekuita clutch actuator
Pamotokari dzese dzeMAZ, KUS dzakafanana pakugadzira dzinoshandiswa.Nheyo yekugadzira ndeye cylindrical body yakaunganidzwa kubva kune matatu akakanda zvikamu - muviri pachawo uye maviri ekupedzisira mavhavha.Mavhavha anowanzo kuve ane flange dhizaini, anonamirwa kumuviri ane screws, gaskets inofanira kushandiswa kuvhara.Muchivharo chepamberi chechiitiko chacho, tsvimbo yehurefu hwakawedzerwa inoiswa zvakasimba, pakuguma kwayo kune forogo yekubatanidza kune yepakati maviri-maoko clutch drive lever.
Muviri wakakamurwa kuita mhango mbiri, imwe neimwe ine threaded channels dzekubatanidza hoses.Mugomba repamberi pane vharafu, munzvimbo yakajairika yechitubu yakatsikirirwa pachigaro chayo (mubasa rayo ikora pakati pemakomba).Iyo chiteshi mugomba repamberi ndiyo inopa - kuburikidza nayo mweya wakamanikidzwa unopiwa kune vharuvhu kubva kune inoenderana inogamuchira yemotokari pneumatic system.
Mugomba rekumashure rekesi kune tsvimbo ine gomo inobuda muvharo yekumashure, uye yakatakura forogo yekunamatira kune maviri-ruoko lever ye clutch fork roller.Tsvimbo ine mhango inotaurirana nemhepo.Tambo inochekwa patsvimbo, iyo iyo inogadzirisa nut inowanikwa pamwe chete ne locknut yayo.Iyo chiteshi mugomba rekumashure inobuda, hose yakasungirirwa pairi, iyo inopa mweya wakamanikidzwa kune amplifier cylinder, pamwe nekubuda kwemhepo kubva mucylinder kudzokera kuKUS kana pedal yaburitswa.
Kushanda kweKUS uye yese PVA ine pneumatic booster iri nyore.Apo clutch pedal inosunungurwa, valve yakavharwa, saka PVA haina kushanda - clutch inobatanidzwa.Kana iyo pedal yakatsikirirwa, KUS, pamwe chete nezvimwe zvikamu, zvinoshanduka kusvikira pakasiyana pakati pekugadzirisa nut pa stem uye chivharo chemashure cheimba inosarudzwa.Muchiitiko ichi, dzinde rinogara pavharuvhu uye rinoisimudza - semhedzisiro, mhepo kubva kumberi kwevhavha inoyerera ichipinda mugomba rekumashure uye inopinda mu clutch booster cylinder kuburikidza nehose.Pasi pesimba remhepo yakamanikidzwa, silinda piston inoshanduka uye inoita kuti kutenderera kwe clutch fork roller - inosimudza ndiro yekumanikidza uye inobvisa clutch.Kana iyo pedal yaburitswa, maitiro ari pamusoro anoitika mune reverse order, vharuvhu inovhara uye mhepo kubva kune amplifier cylinder kuburikidza neshure kumashure kweKUS uye mhango mutsvimbo yayo inopinzwa mumhepo, simba rinobva paforogo. yabviswa uye clutch inoitwa zvakare.

Zviyero zvevhavha uye chikamu-chepakati chemakomba ose zvinosarudzwa kuitira kuti mhepo inosvika kune cylinder yePVA amplifier iitwe nokukurumidza, uye mhepo inoputirwa mumhepo nekuderera kuduku.Izvi zvinowana kubatanidzwa kwakatsetseka kweclutch uye kuderedzwa kweyero yekupfeka kwese kukwesha zvikamu.
Nomenclature uye kushanda kweMAZ mavharuvhu e clutch actuator activation
akati wandei emhando dzeKUS anoshandiswa pamarori eMAZ:
- Katsi.nhamba 5335-1602741 - yeMAZ-5336, 5337, 54323, 5434, 5516, 5551, 6303, 64255. Inopiwa pasina hoses, kugadzirisa nzungu nemaforogo;
- Katsi.nhamba 5336-1602738 - nokuda kweMAZ-5336 uye 5337 motokari dzekuchinja kwakasiyana-siyana.Iine dzinde rakapfupikiswa re 145 mm, rinouya rakakwana nehosi;
- Katsi.nhamba 54323-1602738 - ine tsvimbo pfupi ye80 mm, inouya yakakwana nehose;
- Katsi.nhamba 5551-1602738 - nokuti MAZ-5337, 54323, 5551 motokari.Iine hunde ye 325 mm, inouya yakakwana nehosi;
- Katsi.Nhamba 63031-1602738 - ine hunde ye 235 mm, inouya yakakwana nehose.
Mavharuvhu anosiyana mukugadzirwa uye kukura kwemuviri, kureba kwemadzinde/tsvimbo uye kureba kwehosi.Zvikamu zvinopihwa kumusika mune akasiyana masisitimu - asina hose uye ane hose, mune yechipiri kesi, erabha hose ine dziviriro nenzira yechitubu chakamonyoroka uye neyakajairwa yekubatanidza fittings nemubatanidzwa nzungu inoshandiswa.
Nyaya dzekusarudza, kutsiva uye kugadzirisa kweMAZ valve yekubatanidzwa kweclutch actuator
KUS inzvimbo yepneumatic, iyo inowedzera pasi pemichina mitoro uye mhedzisiro yezvakaipa zvakatipoteredza zvinhu.Zvose izvi zvinotungamirira pakupfeka zvishoma nezvishoma kwevhavha uye zvinogona kukonzera kukanganisa kwakasiyana-siyana - kukuvadzwa kwevhavha, mhepo inoputika kuburikidza nezvisimbiso, deformation yetsvimbo uye tsvimbo, kukanganisa kwemuviri, "subsidence" yezvitubu, nezvimwewo.
Kuti utsive, zvakakosha kutora valve yemhando imwechete uye muenzaniso wakaiswa pamotokari kare, kana kuti inokurudzirwa seanalogue inogamuchirwa nemugadziri.Pano inofanira kurangarirwa kuti mavharuvhu emhando dzakasiyana-siyana ane maitiro akasiyana uye zviyero, saka chikamu che "chisiri chechizvarwa" chinogona kunge chisina kungowira panzvimbo, asiwo hachina chokwadi chekushanda kwe clutch drive.
Paunenge uchitenga valve, iwe unofanirwawo kufunga nezvemichina yayo, kana zvichidikanwa, ungangoda kutenga mamwe hose, mapulagi uye fasteners.Kuti udzivise mari isingakoshi uye kurasikirwa kwenguva, zvinodikanwa kuti utarise nekukurumidza mamiriro ezvikamu mudhiraivha, fasteners uye hoses.
Kutsiva vharafu kunofanira kuitwa maererano nemirayiridzo yekugadzirisa motokari, asi kazhinji kushanda uku kunosvika pakungobvisa chikamu chekare uye kuisa imwe itsva, asi mhepo inofanira kubuda ropa kubva kupneumatic system.Zvadaro zvakakosha kugadzirisa valve uchishandisa nut pahunde yayo - kureba pakati payo uye chivharo chemashure chemuviri weKUS inofanira kuva 3.5± 0.2 mm.Zvadaro, zvose zvinogara zvichigadziriswa zvevhavha inoderedzwa kusvika pakuongorora kwayo kwekunze uye kugadziriswa kwemvumo yakataurwa.
Kana iyo KUS yakasarudzwa uye yakaiswa zvakanaka, ipapo kushanda kweclutch drive yeMinsk rori ichave yakavimbika uye ine chivimbo mune chero mamiriro ekushanda.
