Ukulungiswa kwe-CCGT ezimotweni ze-MAZ

Iyunithi ye-CCGT ku-MAZ yakhelwe ukunciphisa amandla adingekayo ukuze kukhishwe i-clutch. Imishini inezingxenye zomklamo wayo, kanye nemikhiqizo ye-Wabco engenisiwe. Isibonelo, i-PGU Vabko 9700514370 (ye-MAZ 5516, 5336, 437041 (Zubrenok), 5551) noma i-PGU Volchansky AZ 11.1602410-40 (efanele i-MAZ-5440). Umgomo wokusebenza kwamadivayisi uyafana.

Idivayisi nenqubo yokusebenza

Ama-amplifiers we-Pneumohydraulic (PGU) akhiqizwa ngokuguqulwa okuhlukahlukene, ahluke endaweni yemigqa kanye nomklamo webha yokusebenza kanye ne-casing yokuzivikela.

Idivayisi ye-CCGT ihlanganisa izingxenye ezilandelayo:

• i-hydraulic cylinder efakwe ngaphansi kwe-clutch pedal, kanye nepiston nesiphethu sokubuya;
• ingxenye yomoya, kufaka phakathi i-piston, induku kanye nesiphethu sokubuya esivamile kuma-pneumatics nama-hydraulics;
• indlela yokulawula efakwe i-diaphragm ene-valve yokukhipha umoya kanye nesiphethu sokubuya;
• indlela ye-valve (i-inlet ne-outlet) enesiqu esivamile kanye nesici esinwebekayo sokubuyisela izingxenye endaweni engathathi hlangothi;
• induku yenkomba yokugqoka liner.

Ukuqeda izikhala ekwakhiweni kunemithombo yokucindezela. Azikho izikhala ekuxhumekeni nemfoloko yokulawula i-clutch, ekuvumela ukuthi ulawule izinga lokuguga kwemigqa yokushayisana. Njengoba ubukhulu bezinto kuncipha, i-piston ingena ijula ​​endlini ye-amplifier. I-piston isebenza kunkomba ekhethekile eyazisa umshayeli ngokuphila kwe-clutch esele. Ukushintshwa kwediski elishayelwayo noma amaphedi kuyadingeka lapho ubude be-probe bufinyelela ku-23 mm.

I-clutch booster ifakwe into efanelekile yokuxhuma ohlelweni oluvamile lwe-pneumatic yeloli. Ukusebenza okuvamile kweyunithi kungenzeka ngokucindezela emiseleni yomoya okungenani engu-8 kgf/cm². Kunezimbobo ezi-4 zamabhawodi e-M8 zokunamathisela i-CCGT ohlakeni lweloli.

Indlela idivayisi esebenza ngayo:

1. Uma ucindezela i-clutch pedal, amandla adluliselwa ku-piston ye-hydraulic cylinder. Kulokhu, umthwalo usetshenziswa eqenjini le-piston le-pusher.
2. Umlandeli uqala ukushintsha ngokuzenzakalelayo indawo yepiston kuyunithi yamandla womoya. I-piston isebenza ku-valve yokulawula ye-pusher, ivula ukunikezwa komoya emgodini we-cylinder ye-pneumatic.
3. Ukucindezela kwegesi kusebenza ngamandla kwimfoloko yokulawula i-clutch ngesiqu esihlukile. Iketango le-pushrod lilungisa ngokuzenzakalelayo ingcindezi ngokusekelwe ekutheni unyawo lwakho lucindezela kangakanani ku-clutch pedal.
4. Lapho i-pedal ikhishwa, umfutho we-fluid uyakhululwa bese i-valve yokuhambisa umoya ivala. I-piston yesigaba somoya ibuyela endaweni yayo yasekuqaleni.

Amaphutha

Ukungasebenzi kahle kwe-CCGT ezimotweni ze-MAZ kufaka phakathi:

1. Ukuhlanganiswa komhlangano ngenxa yokuvuvukala kwemikhono yokuvala.
2. Ukusabela kwe-actuator ebambezelekile ngenxa yokunamathela koketshezi olujiyile noma i-actuator pushrod piston.
3. Ukwandisa umzamo kumaphedali. Isizathu sokungasebenzi kahle kungase kube ukwehluleka kwe-valve yokuhambisa umoya ocindezelweyo. Ngokuvuvukala okunamandla kwezakhi zokuvala, i-pusher jams, ebangela ukwehla kokusebenza kahle kwedivayisi.
4. I-Clutch ayikhiphi ngokuphelele. Iphutha lenzeka ngenxa yokumiswa okungalungile kokudlala kwamahhala.
5. Ukwehlisa izinga loketshezi ethangini ngenxa yokuqhekeka noma ukuqina komkhono wokuvala.

Isevisi

Ukuze uhlelo lwe-clutch (i-disk eyodwa noma i-double-disk) yeloli ye-MAZ isebenze kahle, kuyadingeka ukugcinwa hhayi kuphela komshini oyinhloko, kodwa futhi nomsizi - i-pneumatic booster. Ukunakekelwa kwesayithi kuhlanganisa:

• okokuqala, i-CCGT kufanele ihlolelwe umonakalo wangaphandle ongaholela ekuvuzeni koketshezi noma umoya;
• qinisa zonke izikulufo zokulungisa;
• khipha i-condensate kusuka ku-booster ye-pneumatic;
• kuyadingeka futhi ukulungisa ukudlala kwamahhala kwe-pusher kanye ne-clutch ethwala ukukhululwa;
• wopha i-CCGT bese wengeza uketshezi lwamabhuleki endaweni yokugcina amanzi ezingeni elidingekayo (ungaxubi uketshezi lwezinhlobo ezahlukene).

Ungashintsha kanjani

Ukushintshwa kwe-CCGT MAZ kunikeza ukufakwa kwamapayipi amasha nemigqa. Wonke ama-node kufanele abe nobubanzi bangaphakathi okungenani obuyi-8 mm.

Inqubo yokushintsha iqukethe lezi zinyathelo ezilandelayo:

1. Nqamula imigqa kumhlangano wangaphambilini bese uqaqa amaphuzu okunamathiselwe.
2. Susa ukuhlanganisa emotweni.
3. Faka iyunithi entsha endaweni yayo yokuqala, buyisela imigqa eyonakele.
4. Qinisa amaphuzu okunamathiselwe ku-torque edingekayo. Izinto ezigugile noma ezigqwalile zinconywa ukuthi zishintshwe kufakwe ezintsha.
5. Ngemuva kokufaka i-CCGT, kuyadingeka ukuhlola ukungahambi kahle kwezinduku zokusebenza, okungafanele kudlule u-3 mm.

Indlela yokulungisa

Ukulungiswa kusho ukushintsha ukudlala kwamahhala kwe-clutch yokukhulula. Igebe lihlolwa ngokususa i-lever yemfologo kude nendawo eyindilinga yenothi le-booster pusher. Ukusebenza kwenziwa ngesandla, ukunciphisa umzamo, kuyadingeka ukuhlakaza i-lever spring. Ukuhamba okuvamile kungu-5 kuya ku-6 mm (kukalwa ngerediyasi engu-90 mm). Uma inani elilinganisiwe lingaphakathi kuka-3 mm, kufanele lilungiswe ngokuphendula i-ball nut.

Ngemuva kokulungiswa, kuyadingeka ukuhlola ukushaywa okugcwele kwe-pusher, okumele kube okungenani u-25 mm. Ukuhlolwa kwenziwa ngokucindezela ngokugcwele i-clutch pedal.

Ngamanani aphansi, i-booster ayiwakhiphi ngokugcwele ama-clutch disc.

Ukwengeza, ukudlala kwamahhala kwe-pedal kuyalungiswa, okuhambisana nokuqala kokusebenza kwe-master cylinder. Inani lincike igebe phakathi piston kanye pusher. Ukuhamba okungu-6-12mm okukalwa maphakathi ne-pedal kuthathwa njengokujwayelekile. Ukuvunyelwa phakathi kwepiston nepusher kulungiswa ngokuguqula iphinikhodi eccentric. Ukulungiswa kwenziwa nge-clutch pedal ekhululwe ngokugcwele (kuze kube yilapho ihlangana nesitobhi senjoloba). Iphinikhodi izungeza kuze kube yilapho kufinyelelwa khona ukudlala kwamahhala okufunayo. I-nati yokulungisa ibe isiqiniswa futhi iphinikhodi yokugunda iyafakwa.

Ungampompa kanjani

Kunezindlela ezimbili zokumpompa kahle i-CCGT. Eyokuqala ine-supercharger eyenziwe ekhaya. Ukupompa kwe-CCGT kwa-MAZ kwenziwa kanje:

1. Yenza idivayisi yokucindezela ekhaya kusuka ebhodleleni lepulasitiki elinomthamo wamalitha angu-0,5-1,0. Kubhojwa izimbobo esivalweni nangaphansi, lapho kufakwa khona izingono zamathayi angenamashubhu.
2. Kusukela engxenyeni efakwe phansi kwe-tank, kuyadingeka ukususa i-valve ye-spool.
3. Gcwalisa ibhodlela nge-brake fluid entsha ukuya ku-60-70%. Vala i-valve yokuvula lapho ugcwalisa.
4. Xhuma isitsha nge-hose ku-fitting efakwe ku-amplifier. I-valve engena-spoolless isetshenziselwa ukuxhuma. Ngaphambi kokufaka umugqa, kuyadingeka ukususa isici sokuzivikela futhi ukhulule ukufaneleka ngokuyiguqula 1-2.
5. Nikeza umoya ocindezelwe kusilinda ngevalvu efakwe kukepisi. Umthombo wegesi ungaba i-compressor ngesibhamu sokwehla kwamandla emali amathayi. I-gauge yokucindezela efakwe kuyunithi ikuvumela ukuthi ulawule ingcindezi ethangini, okufanele ibe phakathi kuka-3-4 kgf / cm².
6. Ngaphansi kwesenzo sokucindezela komoya, uketshezi lungena emgodini we-amplifier futhi lususe umoya ngaphakathi.
7. Inqubo iyaqhubeka kuze kunyamalale amabhamuza omoya ethangini lokunweba.
8. Ngemuva kokugcwalisa imigqa, kuyadingeka ukuqinisa ukufaneleka futhi ulethe izinga le-liquid ethangini ngenani elidingekayo. Izinga elitholakala ku-10-15 mm ngaphansi komkhawulo wentamo yokugcwalisa kubhekwa njengokujwayelekile.

Indlela yokuphampa i-reverse ivunyelwe, lapho uketshezi olungaphansi kwengcindezi kunikezwa ethangini. Ukugcwalisa kuyaqhubeka kuze kungabe kusaba khona amabhamuza egesi aphumayo ekufakeni (okwakukade kungasikulungi ngokujika okungu-1-2). Ngemuva kwe-refueling, i-valve iqiniswa futhi ivaliwe kusuka phezulu ngesici sokuzivikela senjoloba.

Ungakwazi ukuzijwayeza indlela yesibili ngokuningiliziwe ngokubuka ividiyo engezansi, futhi imiyalelo yokupompa ilula kakhulu:

1. Khulula isiqu bese ugcwalisa ithangi ngoketshezi olusebenzayo.
2. Khipha i-valve yokuphuma bese ulinda imizuzu eyi-10-15 ukuze uketshezi luphume ngamandla adonsela phansi. Faka ibhakede noma indishi ngaphansi kwejethi.
3. Susa induku ye-lever bese uyicindezela kanzima ize ime. Uketshezi luzogeleza luphume emgodini.
4. Ngaphandle kokukhulula isiqu, qinisa ukufakwa.
5. Dedela insiza ukuze uyibuyisele endaweni yayo yangempela.
6. Gcwalisa ithangi nge-brake fluid.

Ngemuva kokuphuma kwegazi ukuhlangana kwe-CCGT, kunconywa ukuthi uhlole isimo sezinduku zokuxhuma, okungafanele zikhubazeke. Ngaphezu kwalokho, isikhundla senzwa yokugqoka i-brake pad siyahlolwa, induku yayo akufanele iphume emzimbeni we-cylinder we-pneumatic ngaphezu kuka-23 mm.

Ngemuva kwalokho, udinga ukuhlola ukusebenza kwe-amplifier elolini elinenjini egijimayo. Uma kunengcindezi ohlelweni lwe-pneumatic yemoto, kuyadingeka ukucindezela i-pedal esitobhini futhi uhlole ukukhululeka kwamagiya aguqukayo. Amagiya kufanele asuke kalula futhi ngaphandle komsindo ongaphandle. Lapho ufaka ibhokisi elinesihlukanisi, kuyadingeka ukuhlola ukusebenza kweyunithi yomhlangano. Uma kwenzeka ukungasebenzi kahle, indawo yengalo yokulawula kufanele ilungiswe.

Iyiphi indlela yokopha kwe-hydraulic clutch oyisebenzisayo? Ukusebenza kwe-poll kunqunyelwe ngoba i-JavaScript ivaliwe esipheqululini sakho.
