I-Constant velocity universal joint iyithuluzi elixhuma ama-shaft amabili ane-engeli efakiwe noma ukushintsha kwendawo ehlanganyelwe phakathi kwama-shaft, futhi lenze ama-shaft amabili akwazi ukudlulisa amandla ngesivinini esifanayo se-angular.Inganqoba inkinga yesivinini esingalingani sejoyinti elijwayelekile le-cross shaft universal.Njengamanje, isivinini esisetshenziswa kakhulu esingaguquki samalunga wendawo yonke ikakhulukazi ahlanganisa i-ball fork universal joint kanye nekheji yebhola ehlangene yendawo yonke.
Kwi-axle yesiteringi, isondo langaphambili isondo lokushayela kanye nesiteringi.Lapho uphenduka, i-engeli yokuphambuka inkulu, ifinyelela ngaphezu kwama-40 °.Ngalesi sikhathi, inhlanganisela evamile evamile yendawo yonke ene-engeli encane yokuchezuka ayikwazi ukusetshenziswa.Uma i-engeli yokuchezuka yejoyinti elijwayelekile eliyi-universal inkulu, isivinini kanye netorque kuzoshintshashintsha kakhulu.Kunzima ukuthi amandla enjini yemoto adluliselwe emasondweni ngokushelela nangokuthembekile.Ngesikhathi esifanayo, izophinde ibangele ukudlidliza kwemoto, umthelela nomsindo.Ngakho-ke, isivinini esingaguquki sejoyinti lendawo yonke eline-engeli enkulu yokuchezuka, ukudluliswa kwamandla okuzinzile kanye nesivinini se-angular esifanayo kufanele kusetshenziselwe ukuhlangabezana nezidingo.
