Inventor: GIBSON DANIEL W
IPC: B21D26/033
Filed: 2001-01-26
Abstract: A method of manufacturing an axially collapsible vehicle driveshaft assembly includes the steps of: disposing a first tube end 24 within a forming die having a non-circular die cavity; expanding the first tube end outwardly e.g. by mechanical deformation, electromagnetic pulse forming, hydroforming, into conformance with the die cavity; inserting a second tube end 23 within the first tube deformed end and expanding the second tube end outwardly into conformance with the first tube end. After expansion both tube ends include a plurality of inwardly 23b, 24b and outwardly 23a, 24a extending regions acting as cooperating male and female splines. When a relatively large axial force is applied to the ends of the driveshaft 161, the second tube 23 will move axially within the first tube 24, thereby collapsing and absorbing energy.
