Muaj ntau hom log tsheb hauv khw. Thaum koj xav hloov cov log tsheb, koj puas tsis muaj lub tswv yim pib qhov twg thiab yuav xaiv lub log tsheb li cas? Qhov tseeb, "zoo" ntawm cov log tsheb yog "pob" hauv cov log tsheb.
1. Hnav tsis kam, saib "3T" index
Thaum peb xaiv cov log tsheb, peb thawj zaug xav txog cov uas muaj zog, uas yog, cov uas muaj zog hnav tsis kam. Sab ntawm lub log yog cim nrog Treadwear, Traction, thiab Temperature, uas sawv cev rau qhov ntsuas qhov hnyav, traction Performance index, thiab qhov ntsuas kub raws li qhov ntsuas 3T. Ntawm lawv, qhov coj ntsuas ntsuas yog ntsuas ntawm lub log tsheb tread coj kev ua tau zoo thiab kev pabcuam lub neej.
Qhov ntsuas "3T" los ntawm US Department of Transportation. Tsoomfwv Meskas xav kom txhua lub log tsheb uas tuaj rau hauv Tebchaws Meskas yuav tsum tau cim nrog cov kev ntsuas uas sawv cev rau kev ua haujlwm tseem ceeb ntawm lub log tsheb. Qhov no yog tus qauv yuav tsum tau ua rau kev sib koom ua ke ntawm cov log tsheb zoo.
Qhov hnav qhov ntsuas yog sawv cev los ntawm tus lej tshwj xeeb. Tus lej loj dua, qhov zoo dua qhov hnav tsis kam. Qhov kev coj cwj pwm tsuas yog tus nqi siv xam raws li tus qauv log tsheb zoo thiab tsis sawv cev rau qhov kev pabcuam tiag tiag ntawm lub log tsheb.
Piv txwv li, yog tias lub log tsheb muaj qhov hnyav ntawm 400, nws txhais tau hais tias nws hnav tsis kam yog plaub npaug ntawm cov qauv log tsheb nrog tus lej ntawm 100. Nws tsis txhais tau tias lub log tsheb tuaj yeem mus txog plaub npaug ntawm qhov kev ncua deb ntawm tus qauv. log tsheb.
2.Quetness, nyob ntawm tus qauv
Kev ntsiag to kuj yog ib qho tseem ceeb thaum peb xaiv cov log tsheb. Cov log tsheb uas muaj kev ntsiag to zoo tuaj yeem muab peb qhov chaw tsav tsheb zoo.
Lub hauv paus ntsiab lus ntawm cov suab nrov log tsheb yog lub suab nrov tsim thaum lub tread qauv tsoo hauv av, thiab cov suab nrov ntawm cov log tsheb thiab cov log tsheb los ntawm qhov roughness ntawm av.
Tam sim no, cov log tsheb ntsiag to tread blocks ntawm kev ua lag luam feem ntau tau teeb tsa tsis tu ncua, vim tias cov tread blocks feem ntau yog nrog lub suab nrov dua. Tsis tas li ntawd, ntau lub log tsheb muaj qhov sib txawv-pitch tsim ntawm tread blocks, uas kuj yog ib qho qauv tsim uas txo cov suab nrov ntawm lub log.
3. Cov dej ntws tawm, saib cov grooves
Cov grooves thiab cov qauv ntawm lub log tsheb ua haujlwm ua ke los txhim kho cov kua dej, uas yog, cov dej ntws tawm ntawm cov grooves los ntawm cov qauv ntawm lub log tsheb.
Lub ntsiab trench (longitudinal trench) muaj lub peev xwm ua kom muaj zog tshaj plaws. Qhov tob thiab dav dua qhov trench, qhov ua tau zoo ntawm cov dej ntws. Tab sis raws li qhov dav nce, lub log tsheb tuav kuj yuav txo qis, yog li yuav tsum pom qhov sib npaug ntawm qhov taw tes.
Kab rov tav qauv grooves yog rau auxiliary drainage. Qee lub log tsheb yog tsim los nrog cov sipes ntawm cov kwj deg, uas tuaj yeem txiav los ntawm cov yeeb yaj kiab dej thaum lub tsheb tsav tsheb ntawm kev kub ceev, tso cai rau lub tsheb tsav ntawm kev ceev dua ntawm txoj kev uas muaj dej.
4.Tire kev ua tau zoo nyob ntawm cov khoom siv
Cov khoom siv log tsheb txiav txim siab qhov kev ua tau zoo ntawm lub log tsheb thiab yog qhov tseem ceeb ntawm kev thauj khoom thiab kev thauj khoom ntawm lub log tsheb. Nws txoj haujlwm yog los txhawb lub log tsheb, dais lub tsheb thauj khoom, xyuas kom lub zog, cua siab, ruaj khov thiab kev nyab xeeb ntawm lub log tsheb, thiab tiv thaiv lub log deformation.
Cov khoom siv log tsheb kuj tseem tso tawm rau ntawm phab ntsa, thiab cov ntaub ntawv ntawm cov yas thiab cov phab ntsa yog tso tawm cais. Cov khoom siv log tsheb muaj xws li nylon, polyester, polyamide, thiab hlau.
Tau kawg, ntxiv rau cov saum toj no, hom, tus nqi, thiab qauv ntawm lub log tsheb kuj yog qhov tseem ceeb uas peb yuav tsum xav txog thaum xaiv cov log tsheb. Yog li ntawd, peb yuav tsum xaiv cov log tsheb los ntawm ntau qhov ntev raws li peb tus kheej xav tau.
