Steering Shaft
Massive cost savings thanks to a one-piece solution.
The steering shaft is the connection between the steering gear and the steering column. It ensures that the steering behaviour remains unaffected by the relative movements that occur between the driver’s cab and the chassis during driving.
Complete processing by means of cold forming
Alongside the pedals, the steering wheel is the most important interface between the driver and the vehicle. Firstly, the steering shaft connects the steering wheel to the steering gear in a torsionally rigid manner and, secondly, it allows the height of the steering wheel to be adjusted – and is therefore crucial to ensuring an ergonomic and safe sitting position for the driver. Felss uses an approach that differs from other production methods in that its steering shafts are made from one part: this complete processing is possible thanks to the combined rotary swaging and axial forming process. The one-piece approach improves the straightness of the workpiece and reduces production costs by eliminating the need for welding. The cost savings achieved by lightweight steering are so massive that it is even worth making changes after SOP.
