Input hub
Cost-efficient splines in a single work step
Input hubs are one example of the kinds of small drive components found in a car that are especially complex to manufacture due to their intricate geometry. Conventional production is time-consuming and cost-intensive, since various manufacturing processes are used, with some also involving machining. Felss crash tubes enable crash energy to be converted in a controlled manner by relying on defined deformation. The area that is deformed in the event of a crash features precise wall thicknesses and is characterised by high dimensional stability and repeatability – insisting on precision in the manufacturing process ensures proper functionality in the event of a crash. When producing the ready-to-install component, expansion and chamfering are completed in a single process step.
Benefits of the Felss solution at a glance
Stronger
Outstanding surface quality and the best possible material properties thanks to a continuous grain structure.
Resource efficient
No machining waste due to cold forming.
More precise
Consistently high spline quality and an adjustable roller dimension in the range of ± 0.03 mm.
Faster
Application of one internal and one external spline in one clamping – cycle time of 20 seconds.
