Crash tubes are components of a structure that is designed to protect parts of the bodywork and engine against damage in the event of a collision. The front bumper is suspended from two crash tubes. As safety-critical components, crash tubes have to comply with particularly strict requirements.
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.
