Abstract
This design is about automobile universal transmission device based on pro/E.Universal transmission device uses the cross universal joint shaft with elastic spline.In this paper,the sizes of transmission load of universal transmission shafts、cross universal joints、needle bearings、transmission shafts、transmission shafts with spline、flange forks of the universal joint are designed and checked .Besides, the essay tells the modeling process of flange forks of the universal joint、cross universal shafts、intermediate shafts and connected devices by pro/E.At last,we assemble the universal transmission device .In a word,all the sizes meet the needs of the project.
Keywords: universal joint, drive shaft,modeling
