This Felss steering shaft is, in contrast to manufacturing using other processes, produced from one part.
Hollow shafts forward rotational movements and torque between parts that are connected permanently with one another. Hollow shafts are used when weight needs to be reduced or the shaft should have a high characteristic frequency.
With this Felss hollow shaft, a 90° shoulder was realized in the forming process, whereby it was key to manufacture a large step jump with the greatest precision. Felss achieved this with an economical combination of cold forming, milling, tempering, and grinding. The processes used thus ensure the increased strength of the component. Thanks to a cooperative development phase, this hollow shaft combines advanced functional integration with the highest resource efficiency.
67% material savings (in comparison with chopping process).
Higher stability through cold stabilization.
More resource efficiency due to chipless processing.
Shorter cycle times in comparison with alternative processes.
Complex geometries with the highest precision.
