YaMZ-236 yog lub tshuab hluav taws xob qub uas tsim los ntawm JSC Avtodiesel, qub Yaroslavl Tsav Cog. Qhov no V-shaped "rau" tau nrov nyob rau hauv Soviet Union, thiab tom qab nws tawg - thoob plaws hauv lub CIS. Lub cav yog tam sim no siv rau cov tsheb thauj khoom, tsheb laij teb thiab kev sib xyaw ua ke. Nws tuaj yeem pom ntawm cov tsheb uas paub zoo xws li MAZ, KRAZ, URAL, ZIL, nrog rau ntawm K-700 tsheb laij teb.

Cov koom nrog ze tshaj plaws ntawm cov qauv no yog YaMZ-238 rau 8 lub tog raj kheej thiab YaMZ-240 - 12-lub tog raj kheej. YaMZ-236 muaj ntau yam kev hloov kho nrog ntau npaum li cas ntawm horsepower.

History of Creation

Hauv xyoo 1950, Yaroslavl cog tau txais lub xeev tshwj xeeb rau kev tsim cov tshuab hluav taws xob muaj zog dua, uas yuav tsum tau hloov cov YaAZ uas tsis siv lawm. Cov motors no yuav tsum muaj zog dua thiab pheej yig dua li lawv cov neeg ua ntej. Ntawm qhov tod tes, lub xeev xav kom tau txais lub tshuab universal internal combustion engine uas yuav siv tau rau ntau hom.tsheb.

Raws li kev coj noj coj ua ntawm tus tsim qauv zoo tshaj plaws ntawm USSR thiab qhuas tus kws tshawb fawb Chernyshev G. D., lub cav YaMZ-236 tau tsim, nrog rau tag nrho tsev neeg ntawm lub tshuab diesel ntawm lub sijhawm ntawd. Nws kuj tau tsim ib qho kev sib txig sib luag ntawm cov chav nyob rau KAMAZ.

Yog li no, ICE tau yug los, uas los txog niaj hnub no muaj koob npe rau ntau tus. Nws nta lub zog siab, kev ntseeg siab, kho yooj yim, kho yooj yim, thiab pheej yig spare qhov chaw. Cov peev txheej loj thiab kev tswj xyuas cia nws ua haujlwm ncaj ncees tau ntau xyoo.

Production now

Hnub no, kev tsim khoom ntawm YaMZ-236 txuas ntxiv mus, txawm hais tias nws cov neeg ua tiav YaMZ-530 twb muaj lawm. Cov ntim ntawm cov motors muag tsis poob, tab sis vim muaj kev sib ntaus sib tua hauv Ukraine, cov khoom siv rau Kremenchug tsheb sib dhos cog, uas tsim cov tsheb loj KRAZ, tau nres. Tau kawg, cov nroj tsuag Yaroslavl poob ib ntu rau kev muag cov motors, tab sis qhov no tsis txo qis ntau lawm.

Specifications and device

Lub cav YaMZ-236 muaj cov yam ntxwv ua haujlwm siab. Nws yog txawm peem rau nrog 6 lub tog raj kheej, uas yog teem nyob rau hauv parallel thiab muaj ib tug inclination lub kaum sab xis ntawm 90 degrees. Roj nkag ncaj qha rau hauv lub tog raj kheej, uas yog, kev txhaj tshuaj ncaj qha. Lub siab nyob rau hauv lub cav yog 16.5 atmospheres. Lub piston muaj ib txoj kab uas hla ntawm 130 hli nyob rau hauv lub hauv paus thiab 140 hli nyob rau hauv lub kho version, nrog rau nws stroke ntawm 140 hli.

Lub cav yog nruab nrog cov tshuab ua haujlwm siab siab roj twj tso kua mis thiab cov twj tso kua mis, uas ncaj qha thiabtxhaj rau hauv txhua lub tog raj kheej. Txhua lub taub hau thaiv muaj 6 li qub - 3 noj thiab 3 tso pa.

Coling system - kua nrog yuam kev, uas yog nqa tawm siv lub twj tso kua mis dej. Tus tsav yog ib txoj siv uas tig lub twj tso kua mis los ntawm lub crankshaft pulley.

YAMZ-236 lub cav muaj qhov ntim ntawm 11 liters, lub zog ntawm 150 txog 420 horsepower. Ntawm cov qauv tshiab, nws tau nce mus rau 500 hp. Nyob rau hauv kev twb kev txuas nrog rau kev nce nqi ntawm cov roj tariffs manufacturers ntawm YaMZ-236, uas nws noj yog 40 litres ib 100 km, txo tus nqi no rau 25 litres.

Lub tshuab hluav taws xob tseem ceeb tau ua los ntawm cov hlau cam kom txog thaum xyoo 2010, txog thaum nws txiav txim siab hloov mus rau txhuas, zoo li lub tog raj kheej taub hau. Qhov no ua rau nws ua tau kom yooj yim txoj kev kho thiab tho txawv lub tog raj kheej caj dab, thiab honing ua kom raug. Tib lub sijhawm, lub tsev thaiv tsis tau poob nws lub zog qub.

Cov yam ntxwv tseem ceeb ntawm YaMZ-236 qhia tias lub cav muaj qhov tsim qauv yooj yim, uas ua kom yooj yim kho thiab tu.

Kev kho

YaMZ-236, uas yog hloov kho manually, yuav tsum muaj lub cuab yeej tshwj xeeb. Nws suav nrog ntau yam haujlwm. Xav txog cov kev siv yooj yim uas yuav tsum tau ua:

• Kev hloov kho Valve, uas yog ua tiav los ntawm kev sojntsuam tshwj xeeb tsim rau lub cav YaMZ-236. Kev tsim lub cev muaj zog tso cai rau kev ua haujlwm no nrog lub hau npog tshem tawm.
• Kev hloov kho clutch, ntau dua qhov txheej txheem no yog hu ua ntsuas. Nws yog tuav raulub rooj muag zaub tshwj xeeb.
• Kho cov roj los ntawm lub twj tso kua mis.

Txhua yam kev hloov kho tsuas yog ua tiav hauv cov kev pabcuam tsheb, vim lawv xav tau cov cuab yeej tshwj xeeb uas nyuaj rau nrhiav hauv lub nkas-las.

Kev kho mob

Kev pabcuam lub cav YaMZ-236 diesel yog qhov yooj yim heev yog tias koj paub yuav ua li cas thiab yuav ua li cas. Xav txog cov haujlwm tseem ceeb uas suav nrog hauv kev pabcuam:

1. Roj hloov. Feem ntau, rau lub cav no, nws raug nquahu kom siv cov roj nplua nyeem rau cov tshuab diesel ntawm hom M10G2K.
2. Hloov cov khoom lim. Lub cev muaj zog muaj ob peb lub lim dej uas yuav tsum tau hloov txhua 15,000 km. Cov no yog cov lim roj, cov roj lim ntxhib thiab zoo zoo, kho cov khoom siv rau txhua qhov lim.
3. Kev hloov kho, ua lwm yam lus - tshuab txhaj tshuaj.
4. Hloov valve npog gaskets thiab lub tog raj kheej taub hau. Qee zaum, cov ntaub ntawv hauv ob sab phlu ntawm lub pallet raug hloov.
5. Tighten lossis hloov txoj siv sia.

Ntawm no, hauv paus ntsiab lus, yog tag nrho cov haujlwm saib xyuas uas tau ua ntawm YaMZ-236. Txhua yam hloov pauv hauv kev kho tam sim no thiab npaj kho.

Kho

Kev kho lub cav YaMZ-236 tsuas yog ua haujlwm hauv tsheb, vim nws xav tau cov cuab yeej tshwj xeeb thiab cov cuab yeej. Lawv suav nrog xws li cov sawv cev: rau kev tshem tawm thiab sib sau ua ke ntawm lub zog thiab nws cov khoom, sib npaug, kho thiab rau kev sim.

Koj tseem yuav xav tau cov cuab yeej tshwj xeeb:

• tho txawv thiab honing tshuab.
• khoom siv xuab zebthiab polishing lub crankshaft.
• Sab da dej crimping.
• Reamers rau kev sib tsoo valve lub rooj zaum.
• Valve Directional Installation Equipment.
• tshuab dhos thiab milling.
• Injector tu sawv.
• Nias rau nias bearings thiab seals.
• Argon vuam, qee zaum.
• Lwm yam tshwj xeeb lub hom phiaj diesel cav kho cov cuab yeej thiab khoom siv.

Raws li koj tuaj yeem pom los ntawm daim ntawv teev npe, koj yuav xav tau ntau qhov chaw thiab khoom siv uas tsis yog txhua lub tsheb pabcuam tuaj yeem them taus.

Kho lub cav YaMZ-236 yog ua nyob rau hauv ob peb theem. Tag nrho cov ntawm lawv yog heev complex, thiab nqaim-profile kws yog lub luag hauj lwm rau txhua tus. Xav txog txhua theem nyob rau hauv lem:

1. Kev sib tw. Tej zaum, nws twb paub meej tias lub cav combustion sab hauv yog disassembled siv cov cuab yeej txuas ntxiv niaj hnub thiab rab phom cua.
2. Tshuaj ntsuam xyuas qhov tsis raug thiab txiav txim siab cov npe ntawm cov khoom seem yuav hloov.
3. Sib tsoo lub crankshaft thiab npaj lub tog raj kheej thaiv.
4. Ntxuav tag nrho cov khoom seem thiab sib dhos. Nws feem ntau yog nqa nrog cov roj kub kub.
5. Thaum txhua yam npaj tau, kev sib dhos yuav tshwm sim.

Cov txheej txheem ntawm kev rhuav tshem YaMZ-236 yuav siv sijhawm li 6-8 teev. Nws yuav siv sijhawm li 16-20 teev los npaj cov khoom rau kev sib dhos, nyob ntawm qhov nyuaj ntawm kev tawg. Cov txheej txheem sib dhos yuav siv sijhawm txog 36 teev. Nws tag nrho yog nyob ntawm seb hnav tawm lub ntsiab units thiab cov khoom siv li cas thiab lawv npaj tau zoo npaum li cas rau theem kawg.ua haujlwm.

Npaj rau yav tom ntej

Nyob rau xyoo 2020, Yaroslavl cog npaj yuav tsum tsis txhob tsim cov tshuab YaMZ-236, raws li YaMZ-660 tshiab tab tom npaj los hloov nws, uas yuav dhau los ua 100 horsepower ntau zog, thiab lub ntim yuav nce mus rau 12.5 litres. Nyob rau tib lub sijhawm, cov txheej txheem classic ntawm lub tog raj kheej thiab cov li qub yuav nyob twj ywm. Ib qho kev tsim kho tshiab tau npaj los ua lub tshuab hluav taws xob siv hluav taws xob siab, uas yuav muaj tus qauv Euro-5, uas yuav tso cai rau cov cav nkag mus rau hauv lub ntiaj teb kev lag luam. Nws kuj tseem npaj yuav txuas ntxiv cov khoom siv hluav taws xob diesel raws li YaMZ-236.
