Cov qauv thiab kev ua haujlwm ntawm bulldozer

Bulldozer yog hom tseem ceeb ntawm lub ntiaj teb txav tshuab, uas tau muab faib ua hom crawler thiab hom log tsheb raws li txoj kev taug kev. Vim cov log tsheb bulldozers tsawg dua. Kab lus no feem ntau piav qhia txog cov qauv thiab txoj hauv kev ua haujlwm ntawm crawler bulldozers. Cov haujlwm tseem ceeb ntawm bulldozer excavation yog: shoveling, thauj thiab unloading.
Feem ntau ntawm cov bulldozers nrog lub zog ntau dua 120KW siv hydraulic-mechanical kis tau tus mob. Hom bulldozer no los ntawm kev tsim tshuab ntawm peb lub tsheb bulldozers, D155, D85 thiab D65, qhia los ntawm Komatsu Manufacturing ntawm Nyiv. Tom qab localization, nws tau ua tiav raws li TY320, TY220 thiab TY160 yooj yim bulldozers. Txhawm rau ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom hauv ntau yam kev ua haujlwm, kuv lub teb chaws cov tsheb bulldozer tau nthuav dav lawv cov khoom lag luam raws li cov saum toj no peb qhov yooj yim bulldozers, tsim peb series ntawm bulldozers. TY220 bulldozer series muaj xws li TSY220 wetland bulldozer, TMY220 suab puam bulldozer, TYG220 toj siab bulldozer, TY220F hav zoov logging bulldozer, TSY220H huv bulldozer thiab DG45 pipelayer. TY320 thiab TY160 bulldozers kuj nthuav dav cov khoom zoo sib xws. TY160 series kuj suav nrog TSY160L super wetland bulldozer thiab TBY160 bulldozer.
Kev txhim kho thiab nthuav dav ntawm cov khoom siv bulldozer yuav tsum tsis yog tsuas yog ua tau raws li qhov kev hloov pauv ntawm kev ua haujlwm nyob rau hauv kev ua haujlwm sib txawv, tab sis kuj tseem muaj kev sib koom ua ke ntau tshaj plaws (lossis hloov pauv) ntawm qhov chaw nrog cov qauv yooj yim, uas ua rau muaj kev yooj yim zoo rau cov neeg siv hauv kev siv thiab tu. Txhawm rau pab txhawb cov neeg siv los yuav cov khoom siv, cov chaw tsim khoom tau khaws cov lej ntawm Komatsu ntawm Nyiv. Tsuas yog cov khoom tsim los ntawm lawv tus kheej hauv kev hloov kho yog muab tus naj npawb ntawm lawv tus kheej cov chaw tsim khoom.
Crawler bulldozers yog tsim los ntawm cov cav, kis tau tus mob, cov khoom siv ua haujlwm, cov khoom siv hluav taws xob, cab thiab hoods. Ntawm lawv, cov neeg kho tshuab thiab hydraulic kis tau tus mob muaj xws li torque converters, coupling los ua ke, planetary iav fais fab hloov kis tau tus mob, central transmissions, steering clutches thiab steering brakes, zaum kawg drives thiab mus ncig teb chaws systems.
Lub zog tso tawm mechanism tsav lub twj tso kua mis ua haujlwm nyob rau hauv hydraulic system ntawm cov cuab yeej ua haujlwm, lub twj tso kua mis hloov ceev hauv qhov ceev hloov torque hydraulic system, thiab lub twj tso kua mis lub twj tso kua mis hauv lub kauj nres hydraulic system los ntawm cov iav kis tau tus mob thiab spline txuas; lub sprocket sawv cev rau qhov kawg tsav mechanism ntawm qhov thib ob spur iav tsav (nrog rau sab laug thiab sab xis zaum kawg tsav sib dhos); cov khau taug qab muaj xws li kev mus ncig nrog rau kev sib dhos, lub trolley ncej thiab lub rooj sib txoos.
