Method of manufacturing a combined driveshaft tube and yoke assembly
View Patent ↗A method for manufacturing a combined driveshaft tube and yoke assembly includes the initial step of orienting a first component having a first wall thickness and a second component having a second wall thickness to define an overlap region. The first and second components may have the same or different wall thicknesses, may be formed from the same or different materials, and may have the same or different lengths. Portions of the first and second components are deformed to provide the overlap region with a third wall thickness that is the sum of the first wall thickness and the second wall thickness. Lastly, a pair of yoke arms having respective openings therethrough is formed in the overlap region to provide a combined driveshaft tube and yoke assembly. A pair of combined driveshaft tube and yoke assembly can also be manufactured in accordance with this method.
