Moderi nyinshi yimodoka ya MAZ ifite ibyuma bisohora ibyuma bifata ibyuma bifata pneumatike, uruhare rukomeye mumikorere yabyo ikinishwa na valve ikora.Wige byose kubyerekeranye na MAZ clutch actuator valve, ubwoko bwabo nibishushanyo, kimwe no guhitamo, gusimbuza no gufata neza iki gice uhereye ku ngingo.
Nibiki bya MAZ clutch actuator ikora ya valve
MAZ clutch actuator actuator actuator (clutch booster valve, KUS) numuyoboro wa pneumatike utanga isoko hamwe namaraso yumuyaga uhumeka uturutse kuri silindiri ya pneumatike ya booster iyo clutch isezeranye kandi igacika.
Amakamyo ya MAZ ya moderi 500 yumuryango (haba hakiri kare na nyuma ya 5335, 5549), MAZ-5336 igezweho, 5337, 5551, hamwe na MAZ-5432, 6303 hamwe nizindi zimwe zifite ibyuma bifata ibyapa bibiri, bisaba byinshi imbaraga.Kugenzura mu buryo butaziguye ibice nk'ibi biva kuri pedal birarambira cyane umushoferi kandi byangiza cyane ubushobozi bwo gutwara imodoka, kubwibyo, ikindi gice cyinjijwe mumashanyarazi arekura (PVA) yiyi modoka yikamyo - itera pneumatike .
Mu buryo bwubaka, PVA hamwe na pneumatic booster igizwe na disiki ya leveri ihujwe na pedal, silinderi ya pneumatike hamwe nigice cyo hagati - KUS.Silinderi yashizwe kumurongo wimodoka (unyuze mumutwe), inkoni yayo ihujwe binyuze mumaboko abiri kugeza kumurongo wo kurekura.Inkoni ya KUS ihujwe n'ukuboko gutandukanye kwa lever, naho umubiri wa KUS uhujwe na pedal clutch binyuze muri sisitemu y'inkoni na leveri hakoreshejwe inkoni.
LCU byombi bigize imbaraga za lever PVA hamwe nibintu byoroshye byo kugenzura silinderi ya amplifier.Ikimenyetso cyinjiza cya CRU nikibanza nicyerekezo cyimikorere ya pedal pedal: iyo ukanze, LCU itanga umwuka kuri silinderi, ikemeza ko amplifier ifunguye (ni ukuvuga, ihagarika clutch), iyo ari irekuwe, LCU imena umwuka uva muri silinderi mukirere, ikemeza ko amplifier yazimye (ni ukuvuga, clutch irasezerana).Kubwibyo, KUS nigice cyingenzi kumikorere ya clutch, niba idakora neza, birakenewe gusanwa cyangwa kuyisimbuza rwose.Kugirango usane neza, birakenewe kubona amakuru yibanze yerekeranye nubwoko buriho bwa valve, imiterere yabyo nibiranga bimwe.
Imiterere rusange nihame ryimikorere ya MAZ ya valve yo kwishora mubikorwa
Ku modoka zose za MAZ, KUS zisa cyane mubishushanyo zikoreshwa.Ishimikiro ryigishushanyo ni umubiri wa silindrike ukusanyirijwe mubice bitatu - umubiri ubwawo hamwe nibipfukisho bibiri byanyuma.Igifuniko ubusanzwe gifite igishushanyo cya flange, gifatanye kumubiri hamwe na screw, gasketi igomba gukoreshwa mugushiraho ikimenyetso.Mu gifuniko cy'imbere cy'urubanza, hashyizweho inkoni y'uburebure bwiyongereye, ku musozo wacyo hari agafuni ko kwizirika hagati y'amaboko abiri yo hagati.
Umubiri ugabanyijemo ibice bibiri, kimwekimwe cyose kikaba gifite imirongo ihuza imirongo.Mu cyuho cy'imbere hari valve, mumwanya usanzwe wamasoko ukanda kuntebe yayo (muruhare rwayo ni umukufi uri hagati yu mwobo).Umuyoboro uri mu cyuho cy'imbere ni ugutanga - binyuze muri yo umwuka ucanye uhabwa valve uva mu cyuma gikwiranye na sisitemu ya pneumatike.
Mu cyuho cy'inyuma cy'urubanza hari inkoni itoboye isohoka mu gifuniko cy'inyuma, kandi itwaye agafuni ko kwizirika ku maboko abiri y'amaboko y'uruziga.Inkoni ifite umwobo uvugana nikirere.Urudodo rwaciwe ku nkoni, aho umutobe uhindura uherereye hamwe na locknut yacyo.Umuyoboro uri mu cyuho cy'inyuma urasohoka, shitingi irawufatanije, itanga umwuka ucometse kuri silinderi ya amplifier, kimwe n'umwuka uva mu kirere uva muri silinderi ugaruka kuri KUS iyo pedal irekuwe.
Imikorere ya KUS na PVA yose hamwe na pneumatic booster iroroshye.Iyo pedal pedal irekuwe, valve ifunze, nuko PVA idakora - clutch irasezerana.Iyo pedal ikandagiye, KUS, hamwe nibindi bice bigize ibice, ihinduka kugeza igihe itandukaniro riri hagati yimyunyungugu ihindagurika kuruti nigifuniko cyinyuma cyamazu cyatoranijwe.Muri iki gihe, uruti ruhagarara kuri valve ikaruterura - nkigisubizo, umwuka uva mu cyuho cyimbere cya valve winjira mu cyuho cyinyuma hanyuma ukinjira muri silinderi ya booster ikoresheje hose.Bitewe numwuka uhumanye, piston ya silinderi irahinduka kandi ikemeza ko izunguruka ryikariso - izamura icyapa cyumuvuduko kandi ikuraho clutch.Iyo pedal irekuwe, inzira zavuzwe haruguru zibaho muburyo butandukanye, valve irafunga kandi umwuka uva muri silinderi ya amplifier unyuze mu cyuho cyinyuma cya KUS kandi umwobo uri mu nkoni yawo winjizwa mu kirere, imbaraga ziva mu gihuru ni yakuweho kandi clutch irongera gusezerana.
Igikoresho cyo gusohora imashini ya MAZ
Igishushanyo cya MAZ clutch irekura booster valve
Ibipimo bya valve na cross-igice cyibyobo byose byatoranijwe kugirango itangwa ryumwuka kuri silinderi ya PVA amplifier ikorwa vuba, kandi umwuka uhumeka mukirere hamwe no kwihuta gato.Ibi bigera ku gusezerana neza kwa clutch no kugabanya igipimo cyo kwambara cyibice byose byikaraga.
Nomenclature hamwe nibisabwa bya MAZ ya valve kubikorwa bya clutch
Moderi nyinshi zibanze za KUS zikoreshwa ku makamyo ya MAZ:
- Injangwe.nimero 5335-1602741 - kuri MAZ-5336, 5337, 54323, 5434, 5516, 5551, 6303, 64255. Yatanzwe nta shitingi, ihindura imbuto n'imbuto;
- Injangwe.nimero 5336-1602738 - kuri MAZ-5336 na 5337 yimodoka zitandukanye.Ifite uruti rugufi rwa mm 145, iza yuzuye hamwe na hose;
- Injangwe.nimero 54323-1602738 - ifite inkoni ngufi ya mm 80, iza yuzuye hamwe na hose;
- Injangwe.nimero 5551-1602738 - kuri MAZ-5337, 54323, 5551.Ifite uruti rwa mm 325, iza yuzuye hamwe na hose;
- Injangwe.Umubare 63031-1602738 - ufite uruti rwa mm 235, uza wuzuye hamwe na hose.
Imyonga iratandukanye mubishushanyo nubunini bwumubiri, uburebure bwibiti / inkoni n'uburebure bwa hose.Ibice bitangwa ku isoko muburyo butandukanye - nta shitingi hamwe na hose, mugihe cya kabiri, amabuye ya reberi arinzwe muburyo bwamasoko yagoramye kandi hamwe nibikoresho bisanzwe bihuza hamwe nimbuto zubumwe.
Ibibazo byo gutoranya, gusimbuza no gufata neza valve ya MAZ kugirango ushiremo ibikorwa bya clutch
KUS ni pneumatic unit, yongeyeho gukorerwa imizigo ningaruka ziterwa nibidukikije.Ibi byose biganisha ku kwambara gahoro gahoro kandi bishobora gutera imikorere mibi - kwangirika kuri valve, umwuka uva mukidodo, guhindura inkoni ninkoni, kwangiza umubiri, "kugabanuka" kwamasoko, nibindi.
Kubisimbuza, birakenewe gufata valve yubwoko bumwe nicyitegererezo cyashyizwe kumodoka mbere, cyangwa birasabwa nka analogue yemewe nuwabikoze.Hano hakwiye kuzirikanwa ko indangagaciro zubwoko butandukanye zifite imiterere nubunini butandukanye, bityo igice "kavukire" ntigishobora kugwa gusa, ariko kandi ntigishobora no gukora imikorere isanzwe ya disiki ya clutch.
Mugihe ugura valve, ugomba kandi kuzirikana ibikoresho byayo, nibiba ngombwa, urashobora kugura andi mazu, amacomeka na feri.Kugira ngo wirinde ibiciro bitari ngombwa no gutakaza umwanya, birakenewe guhita ugenzura imiterere yibice biri muri disiki, ibifunga hamwe na hose.
Gusimbuza valve bigomba gukorwa hakurikijwe amabwiriza yo gusana imodoka, ariko mubisanzwe iki gikorwa kiza kumanuka gusa gusenya igice gishaje no gushiraho ikindi gishya, mugihe umwuka ugomba kuva amaraso muri sisitemu yumusonga.Noneho birakenewe guhindura valve ukoresheje ibinyomoro kuruti rwayo - intera iri hagati yacyo nigifuniko cyinyuma cyumubiri wa KUS igomba kuba 3.5 ± 0.2 mm.Ibikurikiraho, uburyo busanzwe bwo gufata neza valve bugabanuka kubigenzurwa hanze no guhindura imikorere yabigenewe.
Niba KUS yaratoranijwe kandi igashyirwaho neza, noneho imikorere yimodoka ya clutch yimodoka ya Minsk izaba yizewe kandi yizeye mubikorwa byose.
Clutch irekura ibikorwa bya MAZ
