Lub tsheb nres camshafts tuaj yeem ntsib ntau yam tsis raug thaum lawv lub neej ua haujlwm, uas tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev nyab xeeb ntawm lub braking system.
Ib qho ntawm cov teeb meem tshwm sim yog hnav. Lub cam nto ntawm lub camshaft tiv thaiv kev sib txhuam tsis tu ncua nrog cov khau nres thaum ua haujlwm braking. Nyob rau tib lub sijhawm, qhov no ua rau maj mam hnav tawm ntawm lub cam nto. Raws li kev hnav mus ntxiv, cam's profile hloov pauv, hloov txoj kev txav mus los thiab qhib qib ntawm cov khau nres. Piv txwv li, kev hnav hnyav tuaj yeem tiv thaiv cov khau nres los ntawm kev sib cuag nrog lub nruas nres, ua rau muaj kev sib tsoo ntxiv thiab txo qis kev ua haujlwm ntawm braking.
Fatigue fracture yog lwm qhov ua txhaum loj. Lub camshaft yog raug rau alternating stresses thaum lub sij hawm nquag braking. Yog tias cov khoom siv camshaft muaj qhov tsis zoo los yog yog tias nws ua haujlwm nyob rau hauv cov khoom siv tsis tu ncua, kev qaug zog tuaj yeem pib thiab thaum kawg ua rau tawg. Nyob rau hauv cov xwm txheej ntawm lub camshaft breakage, tag nrho lub braking system tsis ua hauj lwm, ua rau muaj kev nyab xeeb loj.
Qhov saum npoo corrosion kuj tshwm sim. Thaum cov tsheb tau tsav nyob rau hauv cov av noo, ntsev, los yog lwm yam hnyav ib puag ncig, qhov chaw ntawm lub brake camshaft yog qhov ua rau corrosion. Corrosion tsis tsuas yog ua rau lub cev muaj zog ntawm lub camshaft tab sis kuj ua rau cov khoom siv corrosion nkag mus rau lwm cov khoom ntawm lub braking system, exacerbating hnav thiab impeding ib txwm ua hauj lwm ntawm lub brakes.
Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm tus nres camshaft yog qhov tseem ceeb txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
