Nws tuaj yeem hloov cov kab lus tawm ntawm lub piston mus rau hauv cov lus tsa suab, thiab hloov cov roj siab los ntawm lub piston thiab txuas tus pas nrig rau hauv lub zog thiab tawm mus rau sab nraud. Nyob rau tib lub sijhawm, nws tsav cov kab ke sib kis ntawm lub tsheb thiab lub cav. Valve tsheb ciav hlau thiab lwm yam khoom siv pabcuam.

Lub zog ntawm AJ200 Crankshaft yog qhov nyuaj heev. Nws ua haujlwm nyob rau hauv kev sib koom tes ntawm kev hloov pauv roj siab, reciprocating inertial quab yuam thiab nws lub sijhawm, thiab bears loj alternating loads ntawm dabtsi yog khoov thiab torsion. Nyob rau tib lub sijhawm, nws yog qhov sib luag thiab kev sib hloov ceev, yog li yuav tsum muaj qhov sib npaug ntawm qhov sib npaug, thiab khoov thiab sib tw tsis pub dhau ib qho nqi.

Yog li ntawd, 204DTD crankshaft yuav tsum tau ua los ntawm cov ntaub ntawv zoo heev thiab ua raws li txheej txheem kev kho deg nruj. Feem ntau, 45, 40Cr, 35Mn2 thiab lwm yam nruab nrab carbon steel thiab nruab nrab carbon alloy steel yog siv rau tuag forging. Nyob rau hauv xyoo tas los no, ntau cov hlau nplaum tau siv. Tom qab forging lossis casting, txhawm rau txhim kho lub zog qaug zog ntawm G4D3CA diesel cav crankshaft thiab tshem tawm kev ntxhov siab, nws tseem yuav tsum tau nqa tawm kev txhaj tshuaj peening rau saum npoo ntawm phau ntawv xov xwm, thiab cov ces kaum sib npaug yuav tsum tau dov; txhawm rau txhim kho qhov tawv tawv ntawm cov ntawv xov xwm, nws tseem yuav tsum tau ua kom muaj kev kub ntxhov los yog kev kho nitriding rau saum npoo ntawm phau ntawv xov xwm, thiab thaum kawg ua tiav machining. Cam khwb cia Crankshaft Rau Land Rover Discovery kho nyob rau hauv txoj kev no muaj txaus qaug zog lub zog thiab rigidity tiv thaiv dabtsi yog khoov thiab torsion, thiab nyob rau tib lub sij hawm, cov phau ntawv journal muaj ib tug txaus loj txaus siab-bearing nto thiab hnav tsis kam.
