Qhov kev pom zoo ntawm cov dej hloov pauv hloov lub sijhawm nyob ntawm hom kis tau tus mob thiab cov xwm txheej ntawm kev tsav tsheb tiag tiag. Feem ntau, tsis siv neeg kis tau tus mob yuav tsum tau hloov txhua txhua 40,000 mus rau 80,000 kilometers los yog 2 mus rau 3 xyoo, thaum phau ntawv kis tau tus mob yuav hloov mus rau 60,000 mus rau 100,000 kilometers los yog txog 3 xyoo. Lub sijhawm no tsis kho; nquag pib- nres tsav tsheb hauv nroog thiab ntev ntev - kev caij nkoj nrawm tuaj yeem ua kom cov kua dej oxidation. Yog tias lub tsheb muaj kev hloov pauv, cov kua dej muaj ntxhiab tsw, lossis nws cov xim tig dub, nws yuav tsum tau hloov tam sim ntawd txawm tias qhov txwv tsis pub dhau mus. Tsis tu ncua hloov mus rau qhov tsim nyog cov dej sib kis tau zoo tswj lub lubrication thiab txias efficiency ntawm lub kis tau tus mob, tiv thaiv kev txawv txav ntawm cov khoom siv sab hauv, thiab yog ib qho tseem ceeb ntawm kev saib xyuas cov kauj ruam hauv kev ua kom lub tsheb tsav tsheb zoo thiab kis tau tus mob lifespan.
Cov yam ntxwv ntawm cov qauv sib txawv ntawm kev sib kis tau txiav txim siab qhov sib txawv ntawm lawv cov dej hloov logic. Los ntawm txhais tes kis tau tus mob yooj yim sab hauv iav qauv thiab tsuas yog cia siab rau cov iav roj rau cov yooj yim lubrication. Nyob rau hauv ib txwm paved txoj kev thiab tus cwj pwm tsav tsheb ruaj khov, qhov hloov pauv ntawm 60,000 txog 100,000 mais yog qhov tsim nyog. Txawm li cas los xij, yog tias koj nquag tsav tsheb hauv nroog loj, lub clutch feem ntau yog nyob rau hauv ib nrab- koom nrog lub xeev, ua rau lub zog ntawm lub zog thiab ua kom muaj cua sov ntau dua. Qhov no tseem ceeb accelerates qhov degradation ntawm cov kua kis tau tus mob. Hauv qhov no, kev hloov cov kua dej nyob ib ncig ntawm 60,000 mais tuaj yeem tiv thaiv tau cov teeb meem xws li kev hloov pauv thiab cov iav tsis zoo.
Tsis siv neeg kis tau tus mob yog qhov nyuaj tshaj li phau ntawv kis tau tus mob, tshwj xeeb tshaj yog hom AT thiab CVT. Lawv muaj ntau lub phaj clutch, lub cev valve, thiab cov tswj tswj. Cov kua dej tsis yog tsuas yog yuav tsum tau lubricate tab sis kuj tseem ua lub zog xa hluav taws xob nruab nrab thiab cov khoom siv hluav taws xob. Nyob rau hauv kev pib nquag- nres, qhov kub ntawm cov dej sib kis tseem nyob siab, ua rau cov khoom siv ntxiv hauv cov kua dej tau noj sai dua. Hloov cov kua dej txhua txhua 40,000 txog 60,000 mais tuaj yeem tswj tau qhov kev hloov pauv thiab txo qis jerking thiab shocks. CVT kis tau tus mob txawm tias yuav tsum nruj dua rau hom kua dej, yuav tsum tau siv cov CVT kis tau tus mob siab. Kev siv lwm hom kua dej tuaj yeem ua rau txoj siv hlau ua kom plam thiab ua rau kev sib kis tsis ua haujlwm. Lub sijhawm hloov pauv rau CVT kis tau tus mob feem ntau tswj ntawm 60,000 thiab 80,000 mais.
