Matai echando emamiriro ekunze ese
Iwo azvino maitiro emuchando dhizaini dhizaini anoramba akafanana - anofanirwa kupa mapfupi mabhureki madaro, yakavimbika kubata uye kubata - kunyangwe imhando yemamiriro ekunze atinosangana nawo panjanji. Munguva pfupi yapfuura takava nemukana wekuziva vhiri richangoburwa reGoodyear.
Chando munyika yedu hachina kuenzana chete, saka vhiri remazuva ano rechando rinofanirwa kuita zvakanaka kwete chete pane nyowani kana yakazara sinou, ice uye slush, asiwo pane yakanyorova uye yakaoma nzvimbo. Handizvo zvoga, vatyairi vanotarisira matayi aya kuti ape mwero wepamusoro wekunyaradza unoenderana nemaitiro avo ekutyaira. Iro vhiri rinofanirawo kunyarara uye kuderedza kushandiswa kwemafuta. Kutenda kuti matai makuru haafaniri kushandiswa munguva yechando chinhu chekare. Matai akapamhama ane akawanda mabhenefiti: zvirinani kusangana nemugwagwa, mapfupi ekumira madaro, ane chivimbo uye akagadzikana kubata uye nani kubata. Naizvozvo, kusikwa kwetai rakadaro ibasa rehunyanzvi rehunyanzvi, iro, pakati pezvimwe zvinhu, vanotsika vagadziri uye mainjiniya uye nyanzvi mukutsika makomisheni.
Hofori yematayi ekuAmerica, Goodyear, yaparura chizvarwa chechipfumbamwe che UltraGrip9 yechando vhiri muLuxembourg kune vatengi vekuEurope vari kutsvaga matai emumugwagwa akaomarara. Fabien Cesarcon, uyo anoona nezvezvigadzirwa zvekambani iyi muEurope, Middle East neAfrica, akafadzwa nemayedzo ematai panjanji yeko. Inokwevera kutarisa kune sipes uye kumucheto kwemaitiro matsva akagadzirwa neUltraGrip9 kuti ienderane nechimiro chebhanhire retairi, i.e. nzvimbo yekubatanidza yevhiri nemugwagwa, zvakanyanya sezvinobvira. Izvi zvinoreva kuti pasinei nemafambisirwo akaitwa, tai rinopindura nechivimbo parichatyaira rakananga, parinokona, uyewo parinotsika mabhureki uye richimhanya.
Iyo inoshanduka geometry yemabhuraki anoshandiswa inopa yakavimbika kubata munzira. Huwandu hukuru hwembabvu uye sipes akakwira pamapfudzi anovimbisa kuita zvirinani pachando, nepo iyo yakakwira sipe density uye squarer yekubata kumeso inovandudza ice grip, ukuwo hydrodynamic grooves inowedzera hydroplaning kuramba uye inovandudza traction. pachando chiri kunyunguduka. Kune rimwe divi, compact pamapfudzi mabhuroki ane 3D BIS tekinoroji inovandudza mabhureki mashandiro mumwaka wekunaya.
Makwikwi arikuenderera mberi, zvisinei, uye Michelin akafumura iyo Alpin 5 semhinduro yekushanduka kwemamiriro ekunze muEurope, uko, nekuda kwekuderera kwechando, matai echando anofanirwa kuve akachengeteka kwete chete pane yakavharwa nechando, asiwo pamvura, yakaoma. kana migwagwa ine chando. Iyo Alpin 5 yakagadziridzwa ichishandisa advanced tread pattern uye rubber compound tekinoroji nekuchengetedzwa kwechando seyakanyanya kukosha. Nokuti panguva ino yegore, njodzi dzakawanda dzinokonzerwa nekurasikirwa kwekudhonza dzinonyorwa. Nhamba dzinoratidza kuti kubva muna Gumiguru kusvika Kubvumbi, 4% chete yetsaona inonyorwa kana uchityaira pachando, uye kupfuura zvese, kusvika 57%, pamugwagwa wakaoma. Uyu ndiwo mugumisiro weongororo yeTraffic Accident Research Department yeTechnical University of Dresden.Kubva pane zvakabuda muongororo iyi, vagadziri veMichelin vakagadzira vhiri rinopa kukwenya mumamiriro ese echando. MuAlpin 5 iwe unowana akawanda ehunyanzvi matekinoroji, anosanganisira. Iyo yekutsika komisheni inoshandisa inoshanda elastomers kupa zvirinani kubata panzvimbo yakanyorova uye ine sinou uchichengetedza kushomeka kwekutenderera. Iyo nyowani yekuumbwa yakavakirwa pachizvarwa chechina Helio Compound tekinoroji uye ine sunflower mafuta, iyo inobvumira kuchengetedza zvimiro zverabha uye elasticity yayo pakudzika kwakadzika.
Chimwe chitsva ndechekushandiswa kweStabili Grip tekinoroji, iyo yakavakirwa pane yekuzvivharira sipes uye kudzoka kunoshanda kweiyo tread pattern kune yayo yekutanga chimiro. Zvivharo zvekuzvivharira zvinopa optimum tire-to-ground kubata uye yakanyanya kurongeka (inozivikanwa se "trail" athari).
Alpin 5 inoratidzira yakadzika grooves uye yakanyatso gadzirwa mabhuroko ekutsika kuti agadzire katsi-uye-kukambaira mhedzisiro munzvimbo yechando inosangana. Kana zvidhinha zvadzokera kuchimiro chazvo chepakutanga, ma lateral grooves anonyatso bvisa mvura, nekudaro achidzikisa njodzi ye hydroplaning. Sipes ari mumavhiri anotsika anoita sezvuru zvedikidiki kuti awedzere kubata uye kubata. Kuenzaniswa nechizvarwa chakapfuura, iyo Alpin 5 inotsika ine 12% imwe mbabvu, 16% yakawanda notches uye 17% yakawanda rubber maererano nemagrooves nemachaneli.
Continental yakapawo zano rayo reZomowa. Iyi iWinterContactTM TS 850 P. Tayi iri rakagadzirirwa mota dzevatyairi dzepamusoro uye maSUV. Kutenda kune itsva asymmetric kutsika pateni uye 
yakashandiswa tekinoroji mhinduro, vhiri rinovimbisa kuita kwakanyanya kana uchityaira panzvimbo yakaoma uye ine sinou, kubata kwakanaka uye kuderedzwa kwemabhureki madaro. Iro vhiri idzva rinoratidzira akakwira camber angles uye yakakwirira sipe density kupfuura yakatangira. Iyo WinterContact TM TS 850 P inotsika zvakare ine mabhuroko akawanda pane inotsika inokonzeresa mbabvu dzakachinjika. Sipesi dziri pakati pekutsika uye nechomukati mevhiri dzakazadzwa nechando chakawanda, izvo zvinowedzera kukwesha uye kunonatsiridza kukwenya.
TOP chiratidzo
Mutengi anogona kutarisa dhigirii rekupfeka matai, nekuti UltraGrip 9 ine yakakosha chiratidzo "TOP" (Tread Optimal Performance) muchimiro chechando. Iyo yakavakirwa mukati mekutsika uye kana iyo yekutsika ukobvu inodonha kusvika 4mm, chiratidzo chinonyangarika, inonyevera vatyairi kuti tira haachakurudzirwe kushandiswa kwechando uye inoda kutsiviwa.
Zvakanaka panzvimbo dzakaoma
Kunyaradzwa uye kuchengetedzeka mumigwagwa yakaoma kunonyanya kuenderana nekuoma kwemavhiri. Kuti ivandudze parameter iyi, Continental yakagadzira chimiro chekunze chepfudzi reitsva WinterContactTM TS 850 P. Matai ekunze kwebhuroko sipes akagadzirwa kuti awedzere kusimba kwebhuroko. Izvi zvinobvumira kunyanya kunyatsoita kufamba kwetai panguva yekutsanya kona. Panguva imwecheteyo, sipes uye zvivharo zviri padivi remukati revhiri uye pakati pekutsika zvinowedzera kuwedzera kubata.
