Kev sib txhuam hauv ob sab phlu yog cov khoom sib dhos uas muaj kev sib txhuam hauv ob sab phlu thiab cov khaubncaws sab nraud povtseg ntawm cov khoom siv sib txhuam, feem ntau yog siv hauv kev tsim kho tshuab, lub cev muaj zog nres thiab clutches. Ntxiv nrog rau kev ua kom tiav rau pem hauv ntej thiab rov qab hloov ntawm lub ntsiab ncej, kev sib txhuam clutch kuj tseem siv tau los ua tus nres.
Peb cov phaj sib txhuam feem ntau yog siv rau braking. Piv txwv li, deceleration thiab nres yuav tsum tau siv lub braking muaj nuj nqi. Nws yog lub luag haujlwm ntawm cov ntawv sib txhuam kom ua rau peb cov khoom siv nres thiab decelerate, thiab hloov lub zog kinetic rau hauv lub zog cua sov thiab dissipate nws mus rau hauv qhov chaw. ua kom nws nres.
Thiab ntev npaum li cas peb cov ntaub ntawv sib txhuam yuav kav ntev npaum li cas? Qhov zoo ntawm cov phaj sib txhuam ncaj qha cuam tshuam rau peb tus kheej kev nyab xeeb, yog li peb yuav tsum tau kuaj xyuas kev siv cov phaj sib txhuam tsis tu ncua. Kev hnav ntawm cov phaj kev sib txhuam rau cov kab lus ceeb toom thiab lub suab nrov thaum siv ceeb toom peb tias peb yuav tsum tau hloov cov phaj sib txhuam. Raws li ib txwm muaj, lub neej ntawm tus nres nres yog 30, 000 mais. Yog tias cov khoom siv feem ntau braked, cov ntaub thaiv kev sib txhuam yuav hnav sai dua vim kev sib txhuam mus ntev. Thaum cov phaj kev sib txhuam yog hnav hnyav, cov nyhuv braking yuav ua rau mob hnyav dua. Yog tias nws tsis hloov raws sijhawm, cov nyhuv braking yuav ploj mus thiab kev nyab xeeb ntawm kev ua haujlwm yuav raug cuam tshuam. Txhawm rau kom tsis txhob muaj teeb meem kev nyab xeeb tsis tsim nyog, thov xyuas thiab hloov cov ntaub ntawv sib txhuam tsis tu ncua.
