Knuckle yowongolera, yomwe imadziwikanso kuti "ram Angle", ndi imodzi mwamagawo ofunikira a mlatho wowongolera magalimoto, yomwe imatha kupangitsa kuti galimotoyo iziyenda mokhazikika komanso kusamutsa mayendedwe movutikira. Ntchito ya chiwongolero chowongolera ndikusamutsa ndi kunyamula katundu wa kutsogolo kwa galimoto, kuthandizira ndikuyendetsa gudumu lakutsogolo kuti lizizungulira mozungulira kingpin ndikupanga galimotoyo kutembenuka. Poyendetsa galimotoyo, imakhala ndi katundu wosiyanasiyana, chifukwa chake, imafunika kukhala ndi mphamvu zambiri, chiwongolero chowongolera kupyolera muzitsulo zitatu ndi ma bolts awiri ndipo thupi limagwirizanitsidwa, ndikudutsa pamtunda wa dzenje lobowoleza ndi brake system. Galimoto ikamayenda pa liwiro lalikulu, kugwedezeka komwe kumayendetsedwa ndi msewu kupita ku chowongolero kudzera m'matayala ndiye chinthu chachikulu chomwe chiyenera kuganiziridwa pakuwunika kwathu. Powerengera, mtundu wagalimoto womwe ulipo umagwiritsidwa ntchito kugwiritsa ntchito kuthamanga kwamphamvu kwa 4G kugalimoto, ndipo mphamvu yothandizira magawo atatu apakati a bushing la chowongoleredwa ndi mfundo zapakati zamabowo awiri okwera mabawuti amawerengedwa ngati katundu wogwiritsidwa ntchito, komanso ufulu wa node zonse kumapeto kwa nkhope ya flange yolumikizana ndi brake system.
