Method for producing a length-adjustable steering shaft, and length-adjustable steering shaft

A method for producing a length-adjustable steering shaft having a hollow shaft in which a toothed shaft is received so as to be axially telescopic. The toothed shaft has a toothing with teeth on an external circumference that extend in the axial direction and which engages in a form-fitting manner...

Zusammenfassung:	A method for producing a length-adjustable steering shaft having a hollow shaft in which a toothed shaft is received so as to be axially telescopic. The toothed shaft has a toothing with teeth on an external circumference that extend in the axial direction and which engages in a form-fitting manner in an inner toothing of the hollow shaft. A sliding layer of thermoplastic plastics material is at least in portions attached between the inner toothing and the toothing. In order to enable an improved fastening of the sliding layer to the toothing, prior to attaching the sliding layer, form-fitting elements which for forming a form-fitting connection that is effective in the axial direction are brought to engage with the sliding layer are configured in the region of the toothing of the toothed shaft or the inner toothing of the hollow shaft.
