Ib tiam tshiab ntawm Michelin log tsheb.

Thaum kawg ntawm 2011, qhov kev txhawj xeeb ntawm Michelin log tsheb tau tuav ib qho kev nthuav qhia nyob sab Europe ntawm ib tiam tshiab ntawm lub caij ntuj sov log tsheb, uas yuav mus muag rau lub Ob Hlis 2012 xwb. Qhov tseem ceeb hauv kev tsim lub log tsheb tshiab yog tsav kev nyab xeeb thiab, tau kawg, kev phooj ywg ib puag ncig. ecology, thiab tag nrho cov no ntawm tus nqi uas tsis txawv ntawm cov log tsheb ntawm cov tiam dhau los.

Lub log tsheb cim Primacy 3 yuav hloov qhov nrov heev thiab paub zoo. cov khoom yog Primacy HP log tsheb. Lub Primacy log tsheb series yog qhov tseem ceeb tshaj plaws ntawm Michelin lub caij ntuj sov neeg caij tsheb muab, yam tsawg kawg ntawm tus naj npawb ntawm qhov ntau thiab tsawg muaj thiab cov kev xav tau ntawm automakers thiab cov neeg siv.

Lawv yog tsim los rau nruab nrab thiab high-chav kawm ntawv cov neeg nrog caij, xws li los ntawm tsev neeg lub tsheb mus rau cov tsheb uas muaj zog engine siab. Michelin Primacy - tseem raug xaiv Primacy 3 - yog tsim los kom txaus siab rau cov neeg nyiam tshaj plaws ntawm kev nyiam thiab kev tsav tsheb.

Txawm li cas los xij, Primacy 3 yog lub log tsheb tshwj xeeb rau tsawg kawg yog ob qho laj thawj. Thawj thawj zaug, cov log tsheb yog tsom rau kev lag luam loj, thiab cov chaw tsim khoom qhib tau hais tias lawv tau raug coj los ntawm kev tshawb fawb txog kev sib tsoo tsheb hauv lawv txoj kev loj hlob. Nws yog qhov pom tseeb tias txhua lub tuam txhab log tsheb loj muaj cov kev daws teeb meem uas zoo tshaj plaws thiab, qhov tseem ceeb tshaj, kev nyab xeeb tshaj plaws. Txawm li cas los xij, lub log tsheb tsim thiab kev ua tau zoo yog qhov tsis sib xws, thiab tshwj xeeb tshaj yog lub neej tread tuaj yeem ua rau muaj kev sib txawv nrog kev sib tw, thiab kev tuav ntub dej tuaj yeem ua rau muaj qhov tsis sib xws nrog kev ua haujlwm dov, uas yog qhov tseem ceeb tam sim no (qhov qis dua qhov kev tawm tsam, qhov nyuaj dua. yog kom tau txais txiaj ntsig zoo). tuav ntawm qhov chaw ntub dej). Yog li, lub sij hawm no, ib txwm cuam tshuam cov khoom ntawm cov log tsheb tshiab, cov chaw tsim khoom siv cov kev tshawb fawb tshawb fawb txog qhov ua rau thiab cov xwm txheej ntawm cov tsheb sib tsoo hauv cov xwm txheej European feem ntau.

NYEEM DAWB

Lub caij ntuj sov log tsheb nyob rau lub caij ntuj no?

Yam koj yuav tsum paub txog lub caij ntuj no log tsheb

Qhov no yog kev tshawb fawb los ntawm Lub Tsev Haujlwm Saib Xyuas Avariology ntawm University of Dresden, thaum lub sijhawm kwv yees li 20 qhov xwm txheej uas tau tshwm sim nyob rau xyoo tas los no nyob rau hauv ib lub vojvoog ntawm ntau kaum mais ntawm Dresden tau txheeb xyuas. Raws li cov kws tshawb fawb, qhov xwm txheej ntawm txoj kev raug xwm txheej yog qhia txog qhov xwm txheej tsheb khiav hauv Tebchaws Europe. Peb tsuas tuaj yeem cia siab tias qhov no muaj qee yam ua rau txoj kev "nruab nrab" hauv tebchaws Poland. Txawm li cas los xij, cov txiaj ntsig tau nyuaj heev:

- 70% ntawm cov tsheb sib tsoo tiag tiag tshwm sim ntawm txoj kev qhuav. Tsuas yog ib nrab ntawm lawv tau ntsib txhua yam kev sib tsoo (piv txwv li lub log tsheb cuam tshuam rau qhov kev tshwm sim)

- 60% ntawm cov xwm txheej tshwm sim hauv nroog thiab hauv qhov ceev ceev.

- 75% ntawm cov xwm txheej tshwm sim ntawm txoj kev ncaj (ntawm qhov tsuas yog 20% ​​tshwm sim ntawm txoj kev ntub dej).

- Tsuas yog 25% ntawm kev sib tsoo yog kev sib tsoo (tab sis ntau npaum li 50% yog kev sib tsoo ntub dej). Cov xwm txheej no tuaj yeem yog qhov loj tshaj plaws.

- 99% ntawm kev sib tsoo ntawm qhov chaw ntub dej yog kev sib tsoo nrog ib txheej me me ntawm cov dej npog txoj kev, tab sis tsis muaj hydroplaning.

Yog li cov zis yuav tsum yog:

- kev tiv thaiv ntawm cov log tsheb rau hydroplaning (yog li feem ntau tsa txog tam sim no, piv txwv li, hauv kev tshaj tawm) tsis muaj kev cuam tshuam loj rau kev tsav tsheb, vim qhov tshwm sim no tsis tshwm sim hauv kev xyaum.

- Hauv kev xyaum, kev ruaj ntseg thiab kev sib tsoo luv luv ntawm qhov chaw qhuav yog qhov tseem ceeb tshaj plaws rau kev nyab xeeb.

- Tsis tas li ntawd tseem ceeb yog qhov kev ncua deb ntawm lub tsheb thiab tuav lub tsheb ntawm qhov chaw ntub dej (ntub).

Nws yog qhov kev paub no uas tau siv los txheeb xyuas cov khoom ntawm Michelin Primacy 3 lub log tsheb tshiab, uas tau tsim nyob rau hauv peb lub xyoos dhau los, tau them txog 20 lab mais ntawm cov qauv.

Qhov thib ob yog vim li cas vim li cas Primacy 3 yog lub log tsheb tshwj xeeb yog tias nws nyob ze rau kev ua raws li European txoj cai tshiab uas yuav tsum muaj cov chaw tsim khoom log tsheb los kuaj nws thiab muag nws nrog daim ntawv nplaum uas qhia txog peb qhov tseem ceeb: dov tsis kam, ntub braking nrug thiab suab nrov. theem thaum tsav tsheb. Kev muaj peev xwm nyeem thiab nkag siab cov ntawv nplaum no yuav tsum muaj cov khoom sib cais, tab sis nws tsim nyog hais tias Michelin yog ib tus neeg txhawb nqa tseem ceeb ntawm txoj cai no. Dab tsi ntxiv, Michelin thov tias cov ntawv nplaum no, tsim los pab cov neeg yuav khoom xaiv cov log tsheb tsim nyog rau lawv, yuav tsum muaj cov ntaub ntawv hais txog qhov kev cia siab ntawm cov log tsheb ntawm kev muab, vim tias nws yog kev sib haum xeeb ntawm kev ua haujlwm ntev nrog kev sib tw uas nyuaj thiab txhais tau zoo. log tsheb.

Koj tuaj yeem twv tau tias Primacy 3 tshiab tau tsim los ua kom pom qhov ua tau zoo tshaj plaws hauv peb pawg hais txog cov ntawv nplaum uas yuav siv tau hauv ib xyoos.

Tsis zoo li ntau ntawm nws cov neeg sib tw, Primacy 3 lub log tsheb muaj cov qauv zoo sib xws, uas lub tuam txhab hais tias yog ib qho ntawm cov kev lag luam tawm ntawm kev sib tw thiab txoj kab ncaj nraim thiab nres. Tus Primacy 3's tread qauv xav tias tsis zoo, thaum lub channel-rau-rubber deg cheeb tsam piv qhia tias cov kua dej tsis yog qhov tseem ceeb tshaj plaws. Txawm li cas los xij, lub ntsiab lus tseem ceeb tau them rau kev xaiv cov khoom sib xyaw ua ke hauv ib txoj hauv kev kom tau txais qhov siab tshaj plaws tuav ntawm qhov chaw ntub dej. Cov chaw tsim tshuaj paus tau hais tias, hauv paus ntsiab lus, qhov no tsis yog hais txog cov khoom siv thev naus laus zis tshiab, tab sis hais txog kev tau txais tus cwj pwm tshwj xeeb ntawm cov log tsheb hauv ntau yam xwm txheej.

Transverse thiab longitudinal txhav ntawm tread thiab nyiam hnav Txawm li cas los xij, qhov no nyob ntawm qhov tsis kam rau deformity ntawm tus neeg pob taws. Ntawm no Michelin siv cov kev daws teeb meem tshiab nyob rau hauv daim ntawv ntawm kev thaiv tus kheej tread blocks tiv thaiv ib leeg, uas tsuas yog ua tau nrog qhov dav tsawg kawg nkaus ntawm cov channel cais lawv. Yog li ntawd, rau lub log tsheb no, cov cuab yeej ntawm kev tsim cov sipes sib sib zog nqus (qhov khoob hauv cov khoom siv log), ob peb feem kaum ntawm ib millimeter dav, tig los ua qhov tseem ceeb. Michelin cov kws tshaj lij hais tias Primacy 3 tshiab ua haujlwm yuav luag zoo ib yam hauv kev thauj khoom raws li nws ua nyob rau hauv hnyav hnyav, thiab nws tus cwj pwm hauv ntub dej kuj hloov me ntsis.

Kev sib piv cov kev tshawb fawb ywj pheej ntawm Primacy 3 thiab lwm cov log tsheb zoo yuav tsum tau qhia tias nws qhov kev ncua deb ntawm 100 km / h rau xoom yog 2,2 m luv dua plaub lub log tsheb sib tw, ntub dej ntawm 80 km / h thiab 1,5 m luv dua. , ntawm lub ces kaum ntub dej ntawm kwv yees li 90 km / h, qhov nruab nrab ceev ntawm Primacy 3 yuav tsum yog kwv yees li 3 km / h siab tshaj qhov nruab nrab ceev ntawm cov tsheb nrog cov log tsheb sib tw. Ntawm qhov tod tes, dov tsis kam ntawm Primacy 3 (daim ntawv lo "ntsuab" log) yuav tsum qis dua li qhov kev sib tw dov ntawm nws cov neeg sib tw uas nws yuav txuag tau txog li 45 litres roj ib 000-70 km (qhov nruab nrab lub log tsheb me me. ).

Tau kawg, nws yuav tsum nco ntsoov tias cov txiaj ntsig no yuav txawv nyob ntawm, piv txwv li, qhov loj thiab qhov profile ntawm cov log tsheb tau sim. Los ntawm kev ua lag luam, Promacy 3 yuav muaj nyob rau hauv 38 qhov ntau thiab tsawg nrog lub rooj diameters ntawm 15 "mus rau 18", profiles los ntawm 65 mus rau 45%, thiab cov cim ceev H, V, W, thiab Y. Lawv cov qauv tshiab.
