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, ikinyabiziga gihari gikoreshwa mugukoresha umuvuduko wa 4G wihuta kubinyabiziga, kubara imbaraga zifatika zifatika za bushing centre ya bushing ya point ya knuckle hamwe na point de centre yibice bibiri byuzuza umwobo nkumutwaro washyizweho, kandi gabanya dogere 123456 yubwisanzure bwumutwe wose kumpera yanyuma ya flange ihuza sisitemu yo gufata feri.
