Knuckle yowongolera, yomwe imadziwikanso kuti "nyanga ya nkhosa", ndi imodzi mwamagawo ofunikira a chiwongolero chagalimoto, chomwe chimatha kupangitsa kuti galimoto iyendetse bwino ndikusamutsa komwe kumayendera. Ntchito ya chiwongolero chowongolera ndikutumiza ndikunyamula katundu wakutsogolo kwagalimoto, kuthandizira ndikuyendetsa gudumu lakutsogolo kuti lizizungulira mozungulira kingpin kutembenuza galimotoyo. Galimoto ikamayenda, imakhala ndi katundu wosinthika, chifukwa chake imafunika kukhala ndi mphamvu zambiri.
Chiwongolero chowongolera chimalumikizidwa ndi thupi lagalimoto kudzera m'mabawu atatu ndi mabawuti awiri, ndipo chimalumikizidwa ndi ma brake system kudzera pabowo lokwera pamabowo a flange. Galimotoyo ikamayenda pa liwiro lalikulu, kugwedezeka komwe kumaperekedwa kuchokera pamsewu kupita pachiwongolero kudzera pa tayala ndiye chinthu chachikulu chomwe timaganizira pakuwunika kwathu. Powerengera, mtundu wagalimoto womwe ulipo umagwiritsidwa ntchito kuthamangitsa mphamvu yokoka ya 4G pagalimoto, kuwerengera mphamvu yochitirapo kanthu pazigawo zitatu zapakati pazitsulo zowongolera ndi malo apakati a mabowo awiri oyika bawuti ngati katundu wogwiritsidwa ntchito, ndi chepetsani madigiri a 123456 a ufulu wa node zonse kumapeto kwa flange kulumikiza ma braking system.
