摘要

A driveshaft for a motor vehicle has an approximately constant wall thickness and a changing outer diameter which extends analogously to the amplitude of the second basic vibration of the natural bending frequency. In this way it is possible to achieve a distribution of cross-sectional area which is functionally optimized and meets the respective strength requirements. At the same time, torsional stiffness values may be set as required and natural resonance frequency values may be varied. With help of this design it is possible to move the natural resonance frequency of the tubular shaft into a speed range of minimum external excitation energy.
