Tairi inopfeka index tafura - pfungwa, decoding yemakaki
Zviri mukati
Wese mugadziri anofanira kuita chiyero chesimba bvunzo. Matare kupfeka kuramba kumaka chinhu chinodiwa kuti chitupa certification yezvigadzirwa zvemotokari. Munguva yekugadzira, musanganiswa wakakosha weplasticizers uye lubricant inounzwa murubber kuumbwa kuti iwedzere simba uye kupfeka kuramba. Izvi zvinowedzera kupfeka coefficient, kunowedzera kushorwa kwezvinhu kune deformation. Uye inoratidzwa muchimiro cheiyo tradewear coefficient mune pfupiso tafura yekupfeka matai kuramba yakapihwa kune yega yega modhi.
Mamiriro emigwagwa yemotokari inotarisa kuchengetedzwa kwemugwagwa. Indekisi yekupfeka matairi chiratidzo chakakosha chinoshandiswa pamusoro pechigadzirwa kuitira kuti mutengi agone kusarudza nekukurumidza pamusoro pesarudzo yeparamita.
Kunzwisisa Treadwear Tire Wear Index
Kutsvaga kusamira kwevhiri kuri nyore. Uhwu ndihwo hunhu hwekutsika, hunotsanangurwa nezwi rechirungu rekuti treadwear, uye rinoiswa pamusoro pevhiri.
Pfungwa iyi yakaunzwa neAmerican test engineers. Mune mamiriro eiyo saiti yekuyedza, rabha yakaedzwa uye imwe chikamu chakapihwa kune yega yega mhando renji. Muitiro wacho wakabudirira uye wakapararira munyika yose.
Treadwear
Kugadzirisa zvimiro zverubha kutsika hakungobatsiri vanofarira mota uye vanotengesa matayi, asi zvakare kunobvumira zviremera zvekutonga kuwana rumwe ruzivo nezve mota panguva yekuongorora mwaka.
Wese mugadziri anofanira kuita chiyero chesimba bvunzo. Matare kupfeka kuramba kumaka chinhu chinodiwa kuti chitupa certification yezvigadzirwa zvemotokari. Munguva yekugadzira, musanganiswa wakakosha weplasticizers uye lubricant inounzwa murubber kuumbwa kuti iwedzere simba uye kupfeka kuramba. Izvi zvinowedzera kupfeka coefficient, kunowedzera kushorwa kwezvinhu kune deformation. Uye inoratidzwa muchimiro cheiyo tradewear coefficient mune pfupiso tafura yekupfeka matai kuramba yakapihwa kune yega yega modhi.
Chii chinokanganisa Treadwear
Kutanga kupfeka chiyero ndeye 100 units. Iyo coefficient, iyo inoratidzwa pane tira, inoratidza kunaka kwekubata kwevhiri uye nzira yemugwagwa. Rubha, uko iyo treadwear inopfuura zana, inoratidza zvirinani maneuverability, inopa yakakwirira vhiri kugadzikana.
Iyo wear resistance index inoratidzwa sei (kumaka)
Kudomwa kweiyo kupfeka kuramba chiratidzo chetsika inoenda padivi peshoko rekuti treadwear. Indekisi yekupfeka matayi inodudzirwa maererano neyakajairwa. Semuenzaniso, treadwear ye300 yakakwira, uye 80 inoreva kuti vhiri rinoratidza kudonhedza kuramba zvakanaka pazasi pekutanga kukosha.
Chii chinokanganisa kupera kwematayi
Kuongororwa kwerabha kunoteya deformation kuramba matai mudzidziso. Uye zvinosanganisira kutyaira mumigwagwa yakajairwa uye yemhando yepamusoro, izvo zvisiri zvechokwadi muhupenyu chaihwo.
Mukuita, kuchembera kwerabha kunosimudzirwa nezvakawanda zvinosangana zvinhu:
- Kumhanya-mhanya. Kutsvedza uye kuomesa mabhureki kunokonzeresa kuwedzera kudzvanywa. Izvi zvinomutsa kurasikirwa kwe elasticity, iyo inokanganisa mamiriro ezvinhu emateru.
- Thermal properties yemugwagwa. Asphalt inopisa inomhanyisa kuchembera kwerabha kaviri nekukurumidza.
- Mutoro wakawandisa. Kutyaira motokari dzakaremerwa kupfuura muganhu kazhinji kunokanganisa mamiriro ematairi. Iyo rubber sags, iyo inonzi flaking kupfeka inooneka: kuputika kunoonekwa muchikamu chepamusoro nekuda kwekuremerwa.
- Kutyaira pamusoro pemakomba uye migwagwa isina kuenzana. Kurova vhiri mugomba chinhu chinowanzoitika. Muitiro wenguva dzose wekushandisa muchina mumugwagwa wakashata unotungamira mukuzvimba kana hernia pamateru. Iyi ndiyo nzira iyo varidzi vemotokari vanodana chiitiko ichi kana pateni iri patsika ichichinja kana kupera zvachose.
Ko tire index zvinorevei
Mukuwedzera kune zvakanyorwa, "shangu dzekuchinja" dzisati dzasvika nguva dzose dzinotungamirira kupfeka. Kureva, nzendo munguva yechando nekiti yakagadzirirwa zhizha, uye zvinopesana.
Matayi anopfeka index tafura nemugadziri
Kune mumwe nemumwe mugadziri, iyo yekupfeka kuramba indekisi ndeye inotenderwa yakavimbika kupatsanura iyo inofanirwa kuenderana neGOST, kureva, chiyero chemhando.
Tire inopfeka index tafura ine avhareji kukosha kune vanotungamira vanogadzira.

Mugadziri weTire Pirelli anoisa matai akasimba pamusika ane index ye60, asi izvi hazvireve kuti matai haagone kushandiswa. Iwe unongoda kuyeuka kuti hazvina kukodzera kushandiswa kwemaguta. Chinangwa chikuru chekiti dzakadaro ndechekutyaira mumamiriro ekunze akanyarara, akadzikama mumigwagwa yenyika.
Tafura yetsamba yekumhanyisa uye mutoro indices
Paunenge uchitenga, iwe unofanirwa kutarisa pane kusanganiswa kwehunhu. Kutenga matairi ane anopfuura 450 treadwear, asi panguva imwechete kutyora mitemo yekushandiswa, kutambisa mari.
Mukuwedzera, inofanira kurangarirwa kuti chikwata chekutanga, icho chakaenzana nezana, chakagadzirirwa kumhanya kwemakiromita 48 zviuru. Izvi zvinoreva kuti mushure mekukunda chiratidzo ichi, rabha ichave yakasakara zvachose. Iwe uchafanirwa kutsiva materu kare, pasina kumirira kuchembera kwakakwana.
Matai emhando yepamusoro ane yakanaka yekupfeka kuramba dudziro inokubatsira kuti unzwe uine chivimbo munzira uye kudzivirira tsaona yemotokari.
