Abstract

A joint shaft, in particular a universal joint shaft, has first and second axial connection ends and a central part that connects the two connection ends to one another in a torsionally rigid and pivotable manner. At least one intermediate sleeve is provided between a first and a second shaft element with internal gearing having inner teeth, which are distributed over the circumference and extend in the direction of the longitudinal axis, and external gearing with outer teeth, which are distributed over the circumference and extend in the direction of the longitudinal axis. The sleeve is longitudinally displaceable relative to the first shaft element and to the second shaft element and is attached directly or indirectly in a torsionally rigid manner to the first shaft element by way of the intermediate sleeve external gearing and to the second shaft element by way of the intermediate sleeve internal gearing.
