Overheating ntawmnres tsheb
Thaum siv lub tshuab nres tsheb, thaum siv tas li, yuav muaj qhov tshwm sim ntawm "tso cua sov", thiab yuav muaj qhov tshwm sim hnyav heev. Yog li ntawd, lub tshuab nres nres tam sim no yuav txhim kho cov cua sov ua haujlwm ntawm lub nres nres.
Qhov tshwm sim ntawm "thermal decay" yog hais txog qhov tshwm sim uas cov nyhuv braking ntawm lub brakes txo qis los yog ua tsis tiav tom qab qhov kub ntawm lub nres nres tau nce mus rau qee yam thaum lub sij hawm nres nres. Qhov no yog qhov txaus ntshai heev. Yog li ntawd, qhov ntsuas kub tseem ceeb ntawm "thermal lwj" yog qhov tseem ceeb heev. Qhov kev xav pom tseeb yog tias tus nres nres yog mos, txawm tias koj nqis los ntawm tus nres ntau npaum li cas, cov nyhuv tsis pom tseeb, thiab qhov kev ncua deb ntawm lub braking yog elongated. Nrog rau cov txheej txheem sib txawv thiab cov qauv tsim, cov thermal decay kub ntawm cov brake pads txawv heev. Thaum lub ntsuas kub ntawm lub nres nres poob, cov nyhuv braking yuav rov pib dua. Tus thawj brakes yog feem ntau ntawm 250degree-280degree, thiab cov pawm zoo yuav tsum muaj tsawg kawg yog siab tshaj 350degree, yog li peb yuav tsum xaiv qhov zoo hauv kev xaiv, uas cuam tshuam rau peb tus kheej kev nyab xeeb.
Ib qho tshwm sim hnyav dua yog hlawv. Thaum qhov kub ntawm lub nres nres txuas ntxiv nce, cov qauv sab hauv ntawm lub nres nres tau hloov pauv tshuaj, ua rau muaj kev hloov pauv hauv cov qauv molecular. Nws cov tsos mob yog hais txog qhov kub thiab txias thiab kub crystallizing nyob rau saum npoo ntawm lub brakes. Thaum qhov kub hnyiab tsis hnyav, cov khoom ntawm qhov chaw tuaj yeem polished thiab tuaj yeem siv tau ib txwm, tab sis yog tias nws hnyav, nws yuav tsum tau hloov cov pawm tshiab.
