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.

Driveshaft

The fuel pump permits a high delivery pressure with a low degree of pressure fluctuations and can be attached to the internal-combustion engine in a space-saving manner in axial prolongation of the camshaft and can be driven in a simple fashion. In an alternative embodiment of the invention, the fuel pump serves as a tensioning device for a belt or chain drive by virtue of the drive wheel of the fuel pump acting as a belt or chain tensioning roller.
