Iirimu zamavili emigodiukusebenza phantsi kweemeko zokusebenza ezimandundu ngokugqithisileyo: umthwalo ongashukumiyo onzima, impembelelo eqhubekayo esuka kumphezulu wendlela engalinganiyo yomgodi, ukukhuhlana okunamaqhekeza amatye kunye noxinzelelo lwebhayisekile rhoqo. Ngaphandle konyango olululo lobushushu, iirim zentsimbi ezenziweyo kulula ukuba zisokole, ukudinwa kukuqhekeka, ukonakala okusisigxina kunye nokwaphuka ngequbuliso, nto leyo ebanga ixesha elibizileyo kunye neengozi zokhuseleko kwizixhobo zokuthutha imigodi.

Unyango lobushushu yeyona ndlela isebenzayo yentsimbi yokunyenyisa i-microstructure yangaphakathi ye-wheel-rim steel, kunokutshintsha nje imilinganiselo yangaphandle. Inyathelo ngalinye lokufudumeza kunye nokupholisa lijolise kwiindawo ezithile ezibuthathaka kwiirimu zemigodi.
Ukulungisa kususa iinkozo ezingalinganiyo ezibangelwa kukubunjwa okushushu. Emva kokubunjwa, iinkozo zentsimbi zikhula ngokungaqhelekanga. Ngokufudumeza kwiqondo lobushushu elibekiweyo kunye nokupholisa okucothayo, iinkozo zijika zibe ntle kwaye zifane, ngoko ke uxinzelelo aluyi kugxila kwiindawo ezibuthathaka xa umphetho unobunzima obukhulu bemigodi.
Ukucima ngokukhawuleza kwandisa ubunzima. Inkqubo yokupholisa ngokukhawuleza itshixa ubume bekristale eqinileyo ngaphakathi kwentsimbi, isenza ungqameko lukwazi ukumelana nokukhuhla kwentsimbi ekrwada kunye nobutyobo obubukhali basemgodini.
Ubushushu obuphezulu emva kokucima kubalulekile. Intsimbi ecinyiweyo iba lukhuni kodwa ibe brittle. Ubushushu bukhupha uxinzelelo lwangaphakathi kwaye urhwebe ngobulukhuni obungaphelelanga bokuqina okubalaseleyo. Lo mhlaba ugcina ungqameko lomphetho ungagqabhuki xa ubetha imingxuma kwiitonela ezingaphantsi komhlaba okanye imigodi evulekileyo.
Ukuqina komphezulu wendawo yokungeniswa kwendawo kunika isisombululo esijoliswe kuyo. Kuphela indawo yoqhagamshelwano enxitywayo ephezulu iba lukhuni, ngelixa i-rim eyona nto ihlala iqinile. Olu yilo luthintela isiphene esixhaphakileyo: iirim eziqinileyo ezigcwele umzimba wonke ziqhekeka ngokulula phantsi komothuko onzima.
Ngokusebenza okupheleleyo konyango lobushushu, kugqityiweiirimu zevili lemigodiukufumana ubomi obude benkonzo, ukuthoba izinga lokungaphumeleli ngokungalindelekanga kunye nokuziqhelanisa ngcono nothutho lwexesha elide lomthwalo onzima wemigodi.
