Abstract

An arrangement for the relative adjustment of the angle of rotation of a shaft with respect to a driving wheel, particularly a control shaft of an internal-combustion engine, in which a device for frictional damping equipped with a prestressed diaphragm spring is provided between the driving wheel and the shaft. For achieving a frictional damping which does not abate in the case of operationally caused component changes, the diaphragm spring is selected with a course of the characteristic curve which is relatively negative in sections. The diaphragm spring is prestressed such that a spring path is assigned to the diaphragm spring along a predetermined operating range in the relatively negative course of the characteristic curve.
