1, Kuongororwa kweTire uyekutaridzika kwemhando yekuongorora
Chitarisiko chemhando yetai hachifanirwe kuve nehurema hwekutaridzika hunokanganisa zvakanyanya hupenyu hwaro hwesevhisi, senge delamination pakati pezvinhu zvakasiyana-siyana, chipanje senge, waya yekutyoka mhete, mhete yewaya yakanyanya kukwevera kumusoro, tambo dzakawanda dzakadambuka, kuunyana kwetambo yemukati, uye. vhiri rekorona pamucheto netambo. Kana ukashandisa bhanhire rekuputira, chimiro chebhanhire rekushongedza hachifaniri kunge chisina kukwana kana bhanhire rebhanhire harifaniri kuputika.
2, Kuongorora kweTire, kutsika-tsika mavanga uye mavanga
Tai rega rega rekunze rinofanirwa kunge rakashongedzerwa neanosvika mana anooneka mapfekero ekutsika pazvinhambwe zvakaenzana padenderedzwa, uye kureba kwavo hakufanirwe kunge kuri pasi pe1.6 mm.
Tai rimwe nerimwe rinofanira kuva nemavara pamapfudzi kumativi ose zvichiratidza nzvimbo yechiratidzo chokutsika.
3, kuyerwa kwedata rekuongorora matai
1). Kuyerwa kwematairi makuru paramita
Izvo zvinotsanangurwa, mutoro wendege (kana nhanho), inokwana mitoro yekutakura uye inflation pressure, marimu akayerwa, saizi itsva yetayi, saizi yekushandiswa kwepamusoro, static load radius, rolling radius, uye kushandiswa kunobvumirwa kwematayi emotokari kunofanirwa kuenderana neGB/T2978 kana indasitiri yakakodzera. magwaro ehunyanzvi.
2). Tire kuongorora vhiri idzva rekunze kumucheto saizi
Hupamhi hwese uye dhayamita rekunze rechikamu chetairi rinoenderana nezviri muAppendix A,
3). Kunyorerana pakati pechiratidzo chekumhanya kwetai uye kumhanya kwakanyanya kwekutyaira
Kunyorerana pakati pezviratidzo zvekumhanya kwetai uye kumhanya kwakanyanya kwekutyaira kunofanirwa kuenderana nezviri muAppendix B
4). Kunyorerana pakati petayi mutoro wendekisi uye huwandu hwekutakura
Kunyorerana kuri pakati peindekisi yekuremerwa kwetai uye huwandu hwekutakura kunofanirwa kuenderana nezviri muAppendix C.
4, Kuongororwa kweTirekuchengetedzwa kwekuita kuongorora
Zvinoenderana nezvinodiwa, ita bvunzo yesimba rekuita, bead unseating resistance test, durability performance test, low-pressure performance test, uye high-speed performance test pamatairi akatorwa.
1). Kuita simba reTire
Inokodzera diagonal matayi, T-yakaita seyenguva pfupi matai ezvisara, uye matai eradial ane zita reshiyo reshiyo ye50 uye pamusoro. Muedzo wesimba rekuita retai unofanirwa kuve nekukundikana kwesimba risingasviki kukosha kwakatarwa patafura pazasi pane yega yega bvunzo poindi.
2). Tubeless tire bead isingagone kumira
Inokodzera diagonal tubeless matai, T-yakaumbwa kwechinguvana spare matai, uye radial tubeless matayi ane zita reshiyo reshiyo yemakumi mashanu uye pamusoro. Bhanga revhiri rekutangisa kuita bvunzo rinofanirwa kunge riine bhedhi isingagadzike pane imwe neimwe bvunzo nzvimbo isina kudzika pane zvinopihwa patafura iri pazasi.
3). Tire durability performance
Mushure mekusimba kwekuita bvunzo, kudzvanywa kwetayi hakufanirwe kunge kwakaderera pane 95% yeyakatsanangurwa yekutanga bvunzo kumanikidza; Mushure mekunge kuyedza kwapera, hapafanirwe kuve nekudonha, kuputika kweply, kubvisa tambo, tambo yekutyoka, kucheka (kunze kwePTBC matai echando), kutsemuka kwemajoini, kuputika, kana kukanganiswa kwemuviri wevhiri mukutariswa kwechitarisiko. Kana vhiri rakakuvadzwa, mhepo isina mhepo inofanirawo kuongororwa.
4). Low tire pressure performance
Inokodzera matai eradial, asi haisanganisi T-mhando yenguva pfupi yekusiya matai. Mushure meiyo yakaderera yekumanikidza kuita bvunzo yetai, kudzvanywa kwetayi hakufanirwe kunge kwakadzikira pane yakatarwa yekutanga bvunzo kumanikidza, 95%. Mushure mekunge bvunzo yapera, hapafanirwe kuve ne delamination (kutsika, sidewall, ply, airtight layer, bhandi kana buffer layer, tire), kuputika, kuputika, kuputsika, kuputika (kunze kwePTBC matai echando), kuputika kwekubatana, kuputika, uye kushanduka kusina kujairika kwemuviri wevhiri mukutarisa kwekuona.
5). High speed performance yematayi
Mushure mekumhanya-mhanya kwekuita bvunzo, kudzvanywa kwetayi hakufanirwe kunge kwakaderera pane 95% yeyakatsanangurwa yekutanga bvunzo yekumanikidza; Mushure mekuedza kwapera, hapafanirwe kuve ne delamination iri pachena (kutsika, madziro, ply layer, airtight layer, bhandi layer kana buffer layer, tire bead), ply layer cracks, ply stripping, new ply cracking, flower chipping, joint cracking, kuputika, kana kushanduka kusina kujairika kwevhiri panguva yekuongorora kwekuona. Matai ane kumhanya kukuru kwe300km/h kana pamusoro anotenderwa kuve nekuputika kwepamusoro kana kuputika kunokonzerwa nekuputika,
6). Tire rolling resistance performance inspection
Inoshanda kumatai eradial, asi haisanganisi matayi ane zita rekuti rim diayameter code ye<10 uye yezita rerim diayamita kodhi ye>25, pamwe chete neasina matai ekushandisa kwenguva pfupi chete, mavhiri ane chinangwa chakakosha, matai emijaho, uye matai akaiswa. Iyo rolling resistance coefficient yetai haifanire kudarika iyo yakanyanya muganhu kukosha inotsanangurwa mutafura iri pazasi.
7). Relative grip performance yematayi pamvura yemumugwagwa
Inoshanda kumatai eradial, asi haisanganisi matayi ane zita rekuti rim diayameter code ye<10 uye yezita rerim diayamita kodhi ye>25, pamwe chete neasina matai ekushandisa kwenguva pfupi chete, mavhiri ane chinangwa chakakosha, matai emijaho, uye matai akaiswa. Iyo hama yekubata indekisi yemugwagwa wakanyorova pamusoro pevhiri haifanire kunge iri pasi peiyo diki inogumira kukosha inotsanangurwa muTafura 4.
Aya ari pamusoro ndiwo zviyero uye nzira dzekuongorora mota matayi, kusanganisira kuongorora kwemhando yetayi, main parameter kuyerwa, kuchengetedzwa kwekuita ongororo, nezvimwe.
