Steering shaft with cloverleaf

Ready-to-install steering shaft made from a single tube
The steering shaft connects the steering wheel to the steering gear and provides the driver with feedback from the road. Shocks and vibrations should not be conveyed in the process.


Potentials of cold forming for drive shafts
Felss steering shafts are made using the rotary swaging process to create one-piece solutions that meet the toughest of requirements with regard to the internal profile. Felss steering shafts are manufactured from a single tube using the net-shape process. The outer and inner contours are produced in just a few production steps and in a single operation without the need for any further reworking. This reduces production costs while improving the straightness and ensuring the highest geometric accuracy of the component. As a result, Felss can offer economical series production right through to the ready-to-fit component.

Special features of the implemented solution
Benefits of the Felss solution at a glance

Faster
The manufacturing process can be performed on a single system and without the need for any reworking to achieve the desired contour and geometry (net-shape).

Resource efficient
There is no waste in the cold forming process because no machining processes are involved.

More precise
The accuracy of the workpiece’s inner contour is 5/100 in the contour impression over the entire profile length.

Lighter
The hollow component makes the solution really lightweight to enable weight savings.
