Abstract
A driveshaft for a motor vehicle is designed to be asymmetrical, with the center of symmetry of the central tube region or center of gravity of inertia being located outside the tubular shaft center. Thus, it is possible to obtain a driveshaft whose cross sectional area is distributed in such a way that it is functionally optimized and which meets the respective strength requirements, and noise reduction is achieved by displacing the natural resonance frequency of the driveshaft into a region of minimum external excitation.
