Ithebula lokucindezela osayizi bamathayi

Uma ufaka amathayi kwanoma iyiphi imoto, kuyadingeka njalo ukugcina ingcindezi ebekwe umenzi, ngoba ukwehluleka ukuhambisana nalo mthetho obalulekile kuthinta kabi ukusebenza kwamathayi, futhi kuthinta nokuphepha komgwaqo. Yini okufanele ibe ingcindezi efanele amathayi emoto (itafula). Ake sikhulume ngokuncika kwezinga lokupompa esimweni sezulu, izimo zomgwaqo nezindlela zokuhlola.

Kwenzekani uma umfutho wesondo ungabonwa

Izimoto eziningi ezidonsa ngamasondo angaphambili (ezasekhaya nakwamanye amazwe) zikwazi ukuhlonyiswa ngamasondo ane-radius engu-R13 - R16. Nokho, imishini eyisisekelo cishe njalo ihlanganisa R13 futhi R14 amasondo. Inani lengcindezi efanelekile emathayini emoto likhethwa ngokusekelwe kobukhulu bawo ekulayisheni okugcwele. Kulesi simo, kuyadingeka ukucabangela isimo sezulu kanye nezimo zomgwaqo lapho imoto isebenza khona.

Uma amasondo efakwe umoya ngendlela engafanele

• Ukushayela imoto kuzoba nzima, kuzodingeka wenze imizamo eyengeziwe yokuvula isondo lokuqondisa;
• ukugqokwa kwezinyawo kuzokwanda;
• ukwanda kokusetshenziswa kukaphethiloli lapho ushayela ngamathayi aphantshile;
• imoto izoshibilika kaningi, okuyingozi kakhulu uma ushayela eqhweni noma emgwaqeni omanzi;
• kuyoba nokwehla kwamandla ashukumisayo emoto ngenxa yokwanda okuqhubekayo kwamandla okumelana nokunyakaza.

Uma amasondo ephushwe ngokweqile

• Ukwenyuka kokuguga ezingxenyeni ze-chassis. Ngesikhathi esifanayo, yonke imigodi nemigodi emgwaqeni izwakala ngenkathi ushayela. Ukulahlekelwa ukunethezeka kokushayela;
• njengoba amathayi emoto egcwala ngokweqile, indawo yokuxhumana phakathi kwesondo lesondo nendawo yomgwaqo iyancipha ngenxa yalokho. Ngenxa yalokhu, ibanga lokubhuleka landa kakhulu futhi ukuphepha kokusebenza kwemoto kuncishisiwe;
• ukunyathela kuguga ngokushesha, okunciphisa kakhulu isikhathi sokusebenza kwamasondo ezimoto;
• Ukucindezela okwedlulele emathayini lapho ehlangana nesithiyo ngesivinini esikhulu kungabangela i-hernia, ngisho nokuphuka kwesondo. Lesi simo siyingozi kakhulu futhi singaba nemiphumela ebuhlungu.

Iningi labanikazi bezimoto ezinamasondo angu-R13 no-R14 (okuvamile kakhulu ngama-spokes) banesithakazelo kulokhu: kufanele kube yini ingcindezi enkulu emathayi emoto? Ngokwezincomo zomkhiqizi, amathayi we-radius yeshumi nantathu kufanele afakwe umoya kuze kufike ku-1,9 kgf / cm2, namasondo anobukhulu obungu-R14 - kufika ku-2,0 kgf / cm2. Lawa mapharamitha asebenza kuwo womabili amasondo angaphambili nangemuva.

Ukuncika kwengcindezi yamasondo ezimeni zezulu nezomgwaqo

Eqinisweni, kokubili ihlobo nobusika kuyadingeka ukugcina ukucindezela okufanayo kwesondo. Kodwa-ke, akukhuthazwa ukufuthela kancane amathayi ebusika. Lokhu kuyadingeka ukuze:

1. Khulisa ukuzinza kwezimoto emigwaqweni eshelelayo. Ebusika, ukushayela kuba lula futhi kunethezekile ngamathayi athe phantshi.
2. Ukuphepha emgwaqeni kuyathuthukiswa njengoba ibanga lokuma lemoto lincipha kakhulu.
3. Amathayi asebusika anamandla athambisa ukumiswa, okwenza izimo zomgwaqo ezimbi zingabonakali. Ukwanda kokunethezeka kokushayela.

Kumele futhi ukwazi ukuthi ngokushintsha okubukhali kokushisa (isibonelo, ngemva kokuba imoto ishiye ibhokisi elishisayo emakhazeni), ngenxa yezakhiwo ezithile zomzimba, ukwehla kwengcindezi yesondo kwenzeka.

Ngakho-ke, ngaphambi kokushiya igaraji ebusika, kuyadingeka ukuhlola ukucindezela kwamathayi futhi, uma kunesidingo, ukuwafaka umoya. Ungakhohlwa mayelana nokuqapha okuqhubekayo kokucindezela, ikakhulukazi ngesikhathi sokushintsha kwezinga lokushisa nangaphandle kwenkathi.

Umfutho wesondo onconywayo u-R13 ngokufika kwehlobo ngu-1,9 atm.Leli nani libalwa ngokusekelwe eqinisweni lokuthi imoto izolayishwa uhhafu (umshayeli nomgibeli oyedwa noma ababili). Lapho imoto igcwele ngokugcwele, ingcindezi ye-wheelset yangaphambili kufanele ikhuphuke ibe ngu-2,0-2,1 atm, futhi ngemuva - kufika ku-2,3-2,4 atm. Isondo eliyisipele kufanele livuthelwe libe ngu-2,3 atm.

Ngeshwa, indawo yomgwaqo ayilungile, ngakho-ke abashayeli bezimoto abaningi bakhetha ukungawafaki umoya kancane amathayi abo. Ngoba ngenxa yalokhu, wonke ama-bumps nama-bumps emgwaqeni akuzwakali kakhulu uma ushayela. Ngokuvamile ehlobo, umfutho wesondo wehla ngo-5-10%, futhi lapho kufika ubusika, lesi sibalo sikhuphuka kancane futhi sibe ngu-10-15%. Uma ushayela emigwaqweni ebushelelezi, kungcono ukugcina umfutho wesondo otuswe umenzi.

Ngokucabangela zonke izici, itafula lokucindezela amathayi liyahlanganiswa.

Usayizi wediski kanye nerediyasi	Ukucindezela kwesondo, kgf/cm2
175/70 P13	1,9
175 / 65R13	1,9
175/65 P14	2.0
185 / 60R14	2.0

Yini okufanele ibe ingcindezi efanele yamasondo amakhulu

Naphezu kokuthi izimoto eziningi zakuleli nezangaphandle zinamasondo anobubanzi obungu-R14, abanikazi abaningi basafaka amasondo anobubanzi obukhudlwana (R15 no-R16) ukuze bathuthukise ukubukeka kwemoto yabo nokuthuthukisa izici zayo. Ngakho-ke, kuyadingeka ukwazi ukuthi iyini ingcindezi efanele yamathayi alo sayizi?

Lapha, futhi, konke kuncike ezingeni lomsebenzi womshini. Uma ulayisha uhhafu, umkhawulo wengcindezi yesondo akufanele udlule u-2,0 kgf / cm2, lapho ulayisha ngokugcwele leli nani selivele liyi-2,2 kgf / cm2. Uma umthamo omkhulu wemithwalo esindayo uthwalwa esiqwini, ingcindezi ku-wheelset yangemuva kufanele ikhuliswe ngomunye u-0,2 kgf / cm2. Njengoba ubona, ingcindezi emathayini esikhulumi seshumi nane icishe ilingane nomfutho ka-R15 no-R16.

Indlela yokulinganisa ingcindezi: ukulandelana okufanele

Ngeshwa, ngisho nabashayeli abanolwazi kakhulu abayinaki ngokuphelele inqubo yokuhlola ingcindezi yesondo lemoto, bebheka le nqubo njengento engenamsebenzi. Ukucindezelwa kwethayi kuhlolwa kusetshenziswa i-gauge yokucindezela, engakhelwa kupompo noma into ehlukile. Ungakhohlwa ukuthi iphutha lanoma iyiphi igeji yokucindezela ngokuvamile liyi-0,2 kgf / cm2.

Ukulandelana kokulinganisa ingcindezi:

1. Kufanele usethe kabusha igeji yokucindezela.
2. Khumula ikepisi lokuvikela (uma likhona) engonweni yesondo.
3. Namathisela igeji yokucindezela ku-nozzle bese ucindezela kancane ukuze ukhiphe umoya egumbini.
4. Linda kuze kube yilapho isikhombi sensimbi siyama.

Le nqubo kufanele yenziwe nyanga zonke uma imoto isetshenziswa njalo. Isilinganiso kufanele sithathwe ngaphambi kokuhamba, lapho irabha ingakafudumala. Lokhu kuyadingeka ukuze unqume ngokunembile ukufundwa, ngoba njengoba amathayi efudumala, ukucindezela komoya ngaphakathi kwawo kuyanda. Ngokuvamile lokhu kubangelwa ukushayela okuguquguqukayo nokushintsha njalo kwesivinini kanye nokubhuleka kungazelelwe. Ngenxa yalesi sizathu, kuhle ukuthatha izilinganiso ngaphambi kohambo, lapho amathayi emoto esafudumele.

Ukuthi uzofutha amathayi nge-nitrogen noma cha

Muva nje, cishe zonke iziteshi zokushintsha amathayi zinesevisi ebizayo yokugcwalisa amathayi nge-nitrogen. Ukuthandwa kwayo kungenxa yemibono embalwa elandelayo:

1. Ngenxa ye-nitrogen, ukucindezela kumathayi kuhlala kufana lapho eshiswa.
2. Impilo yesevisi yenjoloba iyanda (cishe "ayigugi", ngoba i-nitrogen ihlanzeke kakhulu kunomoya).
3. Amarimu amasondo ensimbi awagqwali.
4. Amathuba okuphuka kwamasondo awabaliwe ngokuphelele, njengoba i-nitrogen iyigesi engashi.

Kodwa-ke, lezi zitatimende zingenye nje i-hype yokuthengisa. Phela, okuqukethwe kwe-nitrogen emoyeni cishe ku-80%, futhi akunakwenzeka ukuba ngcono uma okuqukethwe kwe-nitrogen emathayi kukhuphuka ku-10-15%.

Ngesikhathi esifanayo, akufanele usebenzise imali eyengeziwe bese uphonsa amasondo nge-nitrogen ebizayo, ngoba ngeke kube nenzuzo eyengeziwe kanye nokulimala kule nqubo.
