Joint shaft, in particular universal joint shaft

A joint shaft, comprising:

• a first axial connection end and a second axial connection end;
• a central part disposed to connect said first connection end to said second connection end by way of a torsionally rigid and pivotable connection formed with at least one pivot joint, said at least one first joint having a yoke and said central part having a flange connected to said yoke;
• said central part having a length compensation over a longitudinal axis of the joint shaft between said central part and one of said first or second connection ends, said length compensation including:
• a tubular first shaft element connected to said first connection end and having an internal gearing formed with inner teeth that are distributed over a circumference and extend in a direction of the longitudinal axis;
• and
• a tubular or rod-shaped second shaft element connected to said second connection end and having an external gearing formed with outer teeth that are distributed over the circumference and extend in the direction of the longitudinal axis;
• and
• at least one intermediate sleeve disposed between said first shaft element and said second shaft element, said intermediate sleeve having an intermediate sleeve internal gearing formed with inner teeth that are distributed over the circumference and extend in the direction of the longitudinal axis, and having an intermediate sleeve external gearing formed with outer teeth that are distributed over the circumference and extend in the direction of the longitudinal axis;
• said intermediate sleeve being displaceable in the direction of the longitudinal axis relative to said first shaft element and to said second shaft element, being attached with torsional rigidity to said first shaft element by way of said intermediate sleeve external gearing, and being attached with torsional rigidity to said second shaft element by way of said intermediate sleeve internal gearing;
• said central part having a plurality of axial stops configured to delimit an extending of said second shaft element axially out of said at least one intermediate sleeve and an extending of said at least one intermediate sleeve axially out of said first shaft element;
• said axial stops including a first axial stop formed with a first contact surface on said first shaft element and a second contact surface on said intermediate sleeve, said first and second contact surfaces being formed opposite one another in the direction of the longitudinal axis, and a second axial stop including a first contact surface on said intermediate sleeve and a second contact surface on said second shaft element and positioned opposite said first contact surface of said second axial stop in the direction of the longitudinal axis;
• and
• at least one second contact surface being formed by an annular disk screwed onto an end face of said second shaft element or of said intermediate sleeve, on a side of said annular disk facing the end face.
