Steering Knuckle, izwi kandi ku izina rya "ram Angle", ni kimwe mu bice by'ingenzi bigize ikiraro kiyobora imodoka, gishobora gutuma imodoka ikora neza kandi ikohereza icyerekezo cy'urugendo rwitondewe. Imikorere ya knuckle ni kwimura no kwikorera umutwaro wimbere yimodoka, gushyigikira no gutwara ibiziga byimbere kugirango bizenguruke kuri kingpin hanyuma imodoka ihinduke. Mu buryo bwo gutwara imodoka, ifite umutwaro uhindagurika, kubwibyo rero, birasabwa kugira imbaraga nyinshi, ipikipiki iyobora binyuze mumashamba atatu na bolts ebyiri kandi umubiri urahujwe, kandi unyuze mumurongo wumwobo wa feri na sisitemu ya feri. Iyo ikinyabiziga kigenda ku muvuduko mwinshi, kunyeganyega byanyujijwe hejuru yumuhanda kugera kuri ruline binyuze mumapine nicyo kintu cyingenzi kigomba gusuzumwa mu isesengura ryacu. Mu kubara, ikinyabiziga gihari gikoreshwa mugukoresha umuvuduko wa 4G yikurikiranya ryikinyabiziga, kandi imbaraga zunganira ingingo eshatu zo hagati zihuru zomugozi hamwe nu ngingo yo hagati yibyobo byombi byashizwemo ibarwa nkumutwaro washyizweho, kandi ubwisanzure bwimyanya yose kumaso yanyuma ya flange ihuza sisitemu ya feri irabujijwe.
