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.
Claims17
A one piece driveshaft especially for use in the drive of a motor vehicle with input and output parts, said driveshaft comprising:
- a tubular homogeneous shaft having a central tube region and end regions at both ends, said central tube region being a larger outer diameter than said end regions, toothed receiving regions formed on said end regions for connecting elements with said drive shaft for torque transmitting purposes, and the driveshaft being rotationally symmetrical about a longitudinal axis and asymmetrical with respect to a central plane transverse to the longitudinal axis.
