Tyre coj index table - tswvyim, kev txiav txim siab ntawm cov cim
Txheem
Txhua tus neeg tsim khoom tam sim no yuav tsum ua tus qauv ntsuas lub zog. Tyre hnav tsis kam kos cim yog qhov yuav tsum tau ua ua ntej rau kev lees paub ntawm cov khoom siv tsheb. Thaum lub sij hawm tsim khoom, tshwj xeeb sib tov ntawm plasticizers thiab lubricants yog nkag mus rau hauv cov roj hmab muaj pes tsawg leeg kom muaj zog thiab hnav tsis kam. Qhov no ua rau kom cov coefficient ntawm hnav, ua rau kom cov khoom tiv thaiv kom deformation. Thiab nws yog reflected nyob rau hauv daim ntawv ntawm ib tug tradewear coefficient nyob rau hauv lub ntsiab lus ntawm lub log hnav tsis kam muab rau txhua tus qauv.
Qhov xwm txheej ntawm lub tsheb ramps txiav txim siab txoj kev nyab xeeb. Lub log tsheb coj qhov ntsuas yog qhov cim tshwj xeeb uas siv rau saum npoo ntawm cov khoom kom tus neeg yuav khoom tuaj yeem txiav txim siab tam sim ntawm qhov kev xaiv ntawm qhov tsis muaj.
Nkag siab Treadwear Tire Wear Index
Nrhiav kom paub qhov hnav tsis kam ntawm lub log tsheb yog qhov yooj yim heev. Qhov no yog qhov zoo ntawm treadwear, uas yog txhais los ntawm lus Askiv lo lus treadwear, thiab siv rau saum lub log tsheb.
Lub tswv yim tau qhia los ntawm American test engineers. Nyob rau hauv cov xwm txheej ntawm qhov chaw xeem, cov roj hmab tau sim thiab ib pawg tau muab rau txhua tus qauv. Kev xyaum ua pov thawj ua tiav thiab nthuav dav thoob plaws ntiaj teb.
Treadwear
Kev kho cov khoom ntawm cov roj hmab tread tsis tsuas yog pab cov neeg nyiam tsheb thiab cov neeg muag tsheb, tab sis kuj tso cai rau cov neeg tswj xyuas kom tau txais cov ntaub ntawv ntau ntxiv txog lub tsheb thaum lub caij tshuaj xyuas.
Txhua tus neeg tsim khoom tam sim no yuav tsum ua tus qauv ntsuas lub zog. Tyre hnav tsis kam kos cim yog qhov yuav tsum tau ua ua ntej rau kev lees paub ntawm cov khoom siv tsheb. Thaum lub sij hawm tsim khoom, tshwj xeeb sib tov ntawm plasticizers thiab lubricants yog nkag mus rau hauv cov roj hmab muaj pes tsawg leeg kom muaj zog thiab hnav tsis kam. Qhov no ua rau kom cov coefficient ntawm hnav, ua rau kom cov khoom tiv thaiv kom deformation. Thiab nws yog reflected nyob rau hauv daim ntawv ntawm ib tug tradewear coefficient nyob rau hauv lub ntsiab lus ntawm lub log hnav tsis kam muab rau txhua tus qauv.
Treadwear cuam tshuam dab tsi
Qhov pib hnav tus nqi yog 100 units. Cov coefficient, uas tau qhia rau ntawm lub log tsheb, qhia txog qhov zoo ntawm kev tuav ntawm lub log tsheb thiab txoj kev nto. Roj hmab, qhov twg cov treadwear ntau tshaj 100, qhia tau hais tias zoo maneuverability, muab siab log stability.
Yuav ua li cas yog qhov hnav tsis kam Performance index qhia (kos npe)
Lub npe ntawm qhov ntsuas kev hnav tsis kam ib txwm mus rau ntawm lo lus treadwear. Lub log tsheb coj Performance index yog deciphered piv rau tus qauv. Piv txwv li, treadwear ntawm 300 yog siab, thiab 80 txhais tau hais tias lub log tsheb pov thawj poob zoo hauv qab tus nqi pib.
Dab tsi cuam tshuam rau lub log tsheb
Kev ntsuas roj hmab txiav txim siab qhov deformation tsis kam ntawm cov log tsheb hauv txoj kev xav. Thiab nws koom nrog kev tsav tsheb ntawm cov qauv thiab cov kev ua haujlwm zoo, uas tsis yog ib txwm muaj tseeb hauv lub neej tiag tiag.
Nyob rau hauv kev xyaum, roj hmab aging yog txhawb los ntawm ntau yam concomitant yam:
- Kev nrawm nrawm. zawv zawg thiab nyuaj braking ua rau muaj zog compression. Qhov no provokes poob ntawm elasticity, uas cuam tshuam rau cov xwm txheej ntawm qhov chaw siab tshaj.
- Cov khoom cua sov ntawm txoj kev. Kub asphalt accelerates kev laus ntawm cov roj hmab ob zaug kom sai.
- Ntau dhau load. Tsav tsheb thauj khoom dhau qhov txwv feem ntau cuam tshuam rau lub log tsheb. Cov roj hmab sags, lub thiaj li hu ua flaking hnav tshwm: cov kab nrib pleb tshwm nyob rau hauv sab sauv vim lub load.
- Tsav tsheb hla lub qhov dej thiab qhov chaw tsis sib xws. Kev ntaus lub log hauv lub qhov yog ib qho tshwm sim. Kev ua haujlwm tsis tu ncua ntawm lub tshuab ua haujlwm ntawm txoj kev tsis zoo ua rau o los yog hernia ntawm qhov chaw siab tshaj. Qhov no yog yuav ua li cas cov tswv tsheb hu qhov tshwm sim thaum tus qauv ntawm lub tread hloov los yog tag nrho hnav.
Tire Performance index txhais li cas
Ntxiv nrog rau cov npe no, "hloov khau" tsis tu ncua feem ntau ua rau hnav. Ntawd yog, kev mus ncig hauv lub caij ntuj no nrog cov khoom siv tsim rau lub caij ntuj sov, thiab rov ua dua.
Tyre coj index rooj los ntawm cov chaw tsim khoom
Rau txhua qhov chaw tsim khoom, qhov ntsuas qhov hnyav hnyav yog qhov yuav tsum tau ua kom ntseeg tau tias yuav tsum ua raws li GOST, uas yog, tus qauv zoo.
Tyre coj Performance index rooj nrog qhov nruab nrab qhov tseem ceeb rau cov tuam txhab ua lag luam.

Lub tuam txhab tsim log tsheb Pirelli tso cov log tsheb ruaj khov rau hauv kev ua lag luam nrog qhov ntsuas ntawm 60, tab sis qhov no tsis tau txhais hais tias cov log tsheb siv tsis tau. Koj tsuas yog yuav tsum nco ntsoov tias lawv tsis haum rau kev siv hauv nroog. Lub hom phiaj tseem ceeb ntawm cov khoom siv no yog tsav tsheb nyob rau hauv ntsiag to, huab cua nyob ntsiag to ntawm txoj kev hauv lub tebchaws.
Cov ntawv xov xwm ceev thiab load indices
Thaum muas, koj yuav tsum tsom mus rau kev sib xyaw ua ke ntawm cov khoom zoo. Kev yuav cov log tsheb nrog ntau dua 450 treadwear, tab sis tib lub sij hawm ua txhaum txoj cai ntawm kev siv, yog kev siv nyiaj pov tseg.
Tsis tas li ntawd, nws yuav tsum tau borne nyob rau hauv lub siab hais tias lub pib unit, uas yog sib npaug zos rau ib puas, yog tsim rau ib tug khiav ntawm 48 txhiab kilometers. Qhov no txhais tau hais tias tom qab kov yeej lub cim no, cov roj hmab yuav ploj tag. Koj yuav tau hloov cov nqes hav ua ntej, tsis tas tos kom tiav kev laus.
Cov log tsheb zoo nrog lub ntsiab lus hnav zoo yuav pab koj muaj kev ntseeg siab ntawm txoj kev thiab tiv thaiv kev sib tsoo tsheb.
