Abstract
A driveshaft (6, 8, 9, 11) for a vehicle (1) which is firmly attached to a damping sleeve (17) slid on the central tube region (R.sub.m). The damping sleeve (17) changes the natural and torsional frequencies of the driveshaft (6, 8, 9, 11) thereby permitting the natural frequencies to be moved into the region of low external excitation energy.
