Zvamunoda kuziva pamusoro pematairi echando

Nguva yechando inokurumidza kusvika. Kupisa kuri kuwedzera kutonhora uye saka unogona kuve nechokwadi chekuti mavulcanizers achange akabatikana munguva pfupi iri kutevera. Paunenge uchichinja matayi, zvakakosha kuyeuka iwo akakosha, asi akanyanya kukosha matipi.

S nguva yechando yava kusvika zvisingaite. Kupisa kuri kuwedzera kutonhora uye saka unogona kuve nechokwadi chekuti mavulcanizers achange akabatikana munguva pfupi iri kutevera. Paunenge uchichinja matayi, zvakakosha kuyeuka iwo akakosha, asi akanyanya kukosha matipi.

Vatyairi vematayi emwaka wese nevaya vakaatsiva ivo pakutanga, havafanirwe kushanyira miti inorapa kwechinguva. Avo vachiri kushandisa mavhiri ezhizha, kana vasati vava nemavhiri echando, vanofanira kuatsvaga kare. Ukuwo, avo vanokwanisa kuchovha matayi emwaka wapera wenguva yechando vave kutoronga kushanya kuchitoro chinotengeswa matayi.

Nguva yekushandisa matairi echando?

Nguva yechando yetai

Zvinowanzobvumwa kuti matai echirimo anofanira kuchinjwa kuva matai echando apo tembiricha yekunze inodzika pasi pe7 degrees Celsius uye yogara iri pasi pe zero usiku. Ichokwadi ndechokuti kana mercury column iri pasi pemuganhu uyu, matairi ezhizha anorasikirwa nezvinhu zvavo zvakanaka. Matairi echando, kusiyana nematairi ezhizha, ane rudzi rwakasiyana uye maitiro ekutsika, contour uye anogadzirwa kubva kune yakasiyana-siyana yerubha. Izvo zvinoratidzirwa nekunyorova, kushanduka uye kubata zvakanaka pachando uye nzvimbo dzakanyorova, incl. tichitenda kune mamwe sipes (madiki sipes akagadzirwa muna 1987 naMichelin anowedzera kusangana kwevhiri nevhu). Tai remunguva yechando rinoramba richiita zvakanaka patembiricha inodzika kusvika -20 degrees Celsius.

Matai echando haafanire kushandiswa kana mamiriro avo asingaenderane nemaitiro azvino. Hazvisi zvekudzivirira chete. Tichifunga seti kubva mumwaka wapfuura, inofanira kunyatsotariswa. Wese munhu anogona kuzvimiririra kutarisa mamiriro ekutsika nekutarisa TWI (Tread Wear Indicator), inova 1,6 mm yakakwirira tire kupfeka chiratidzo. Inowanikwa pamatairi munzvimbo dzakawanda. Kana kutsika kwakadzika kwakaenzana kana kudarika kukosha uku, saka matairi akadaro haana kukodzera kushandiswa zvakare. Panyaya ye "matairi echando", inofanira kurangarirwa kuti haizadzisi basa ravo nehupamhi hwekutsika kwepasi pe4 mm. Mvura, slush uye chando hazvizobudiswi zvinobudirira uye hazvizoiti inovimbisa kunamatira kwakakodzera. Rimwe dambudziko ringave mutsauko mukudzika kwekurerutsira kwematayi akaiswa paekisero imwe chete. Kana yakakura kupfuura 5 mm, izvi zvinogona kukonzera, pakati pezvimwe zvinhu, kutakurwa kwemotokari. Iwe unofanirwawo kutarisisa kune ese marudzi ekukuvadza kune tayi, senge deformation, "bubbles", kucheka. Gumbo iri rinoda kuchinjwa.

Matayi echando ane marudzi matatu ekutsika: kutungamira, asymmetric uye symmetrical. Iwo matai anonyanya kufarirwa ane gwara rekutsika anofanira kutevedza rolling direction vector. Panyaya yematairi asymmetrical, kunyorwa kwe "kunze" kunofanira kunge kune rumwe rutivi rwakatarisana nemotokari yemotokari, uye "mukati" - padivi remakumbo emakumbo.

Semuenzaniso, haugone kuisa imwe peya yechando matai pamberi, uye wosiya matai ezhizha kumashure. Zvakanakisa kushandura iyo yese seti uchishandisa matairi emhando imwechete, chimiro uye kutsika mhando. Mota ine mhando dzakasiyana dzemavhiri ichange isingatarisike zvishoma. Kana ari matai akashandiswa, tinoisa mavhiri maviri asingasakara paekisero yekumashure, zvisinei nekuti mota yedu iri pamberi kana kumashure. Izvi zvinovimbisa kubata zviri nani uye kugadzikana mumakona uye panzvimbo dzakanyorova.

Kuti ubvise kuzununguka, zvinodikanwa kuenzanisa mavhiri pane imwe neimwe shanduko yevhiri, ndiko kuti, kuenzanisa ruzhinji rwakatenderedza axis yekutenderera kwevhiri. Chiyero chavo chinodzivirira kupera nguva isati yakwana kwete chete matayi, asiwo kumiswa, kutungamira uye chassis zvikamu. Professional vulcanizers vanokwanisa kukurumidza kuona zvipfeko zvisina kujairika zvematayi. Chikonzero chinogona kunge chisina kunyatsogadziriswa parallelism yegiya uye geometry yayo. Kugadzirisa kwayo kwakarurama kuchawedzera hupenyu hwerabha pamavhiri.

- Haasi munhu wose anoziva kuti pakuchinja matairi, vulcanizer inofanirawo kutsiva valve muvhiri rimwe nerimwe, i.e. mhepo vharafu. Mavharuvhu anochengeta matai akasimba uye zvakare anobvumidza iwe kuti ufure uye utarise kudzvanywa. Nokuatsiva, tichadzivisa kupera simba kwetai patinenge tichityaira. Nechepfungwa, sevhisi yakadaro yatove "inosanganisirwa" mumutengo wekushanyira kune imwe nzvimbo yekuchinja matairi, asi zvakakosha kuve nechokwadi kuti mavharuvhu zvakare matsva, anodaro Justina Kachor anobva kuNetCar sc.

Bhutsu dzechando dzemotokari

Chando mumugwagwa

Vanhu vazhinji vanochinja matayi echando ega. Haisi pfungwa yakaipa kana tiine seti yechipiri yemarimu atove nematayi akaiswa. Zvisinei, inofanira kuyeukwa kuti mavhiri anofanira kuongororwa uye, kana zvichidiwa, akaenzana. Panguva yekushanda, zvinowanzoitika kuti isu tinokuvadza rimu kana kuderedza uremu, saka zvakanaka kuratidza pane vulcanizer uye kuitarisira tisati tapfeka. Ehe, isu hatifanire kukanganwa nezve kwakaringana kumanikidzwa kwetai, nekuti kuchengetedzwa kwedu kunoenderana nazvo. Kudzvinyirirwa kwakakodzera kunowedzerawo hupenyu hwematoyi ako uye kumira kwemotokari. Vagadziri vemotokari vanowanzopa ruzivo rwekumanikidzwa kwakanyanya kunokodzera muenzaniso wakapihwa mukati memafuta ekuzadza mafuta, pamucheto wegonhi, kana paB-pillar parutivi rwemutyairi.
