Gukoresha knuckle, bizwi kandi ku izina rya "ihembe ry'intama", ni kimwe mu bice by'ingenzi bigize ibinyabiziga bigenda neza, bishobora gutuma ibinyabiziga bigenda neza kandi bigahindura icyerekezo cyo gutwara. Imikorere ya knuckle ni ugukwirakwiza no kwikorera umutwaro wimbere wimodoka, gushyigikira no gutwara ibiziga byimbere kugirango bizenguruke kuri kingpin kugirango uhindure imodoka. Iyo ikinyabiziga gikora, gifite umutwaro uhinduka, bityo birasabwa kugira imbaraga nyinshi.
Imashini yimodoka ihujwe numubiri wikinyabiziga binyuze mumashami atatu na bolts ebyiri, kandi ihujwe na sisitemu ya feri binyuze mumwobo wa feri ya flange. Iyo ikinyabiziga kigenda ku muvuduko mwinshi, kunyeganyega kwanduye kuva kumuhanda kugera kumuyoboro unyuze mu ipine nicyo kintu nyamukuru dusuzuma mu isesengura ryacu. Mu kubara, moderi yimodoka ihari ikoreshwa mugukoresha umuvuduko wa 4G yikurikiranya ryikinyabiziga, kubara imbaraga zokwitwara zingingo zitatu za bushing centre ya knuckle hamwe nu ngingo yo hagati yibyobo byombi byashizwemo nkumutwaro washyizweho, kandi bikagabanya dogere 123456 yubwisanzure bwimyanya yose kumpera yanyuma ya flange ihuza sisitemu ya feri.
