Steering Column Bushings
Isolate unwanted steering wheel vibrations and provide progressive damping
Elastomer ribs for axial form fit
Low axial stiffness elastomer layer for good isolation of vibrations
Welded lightweight plastic housing
Integrated stopper system for a progressive torsional stiffness
Steering column bushings isolate vibrations in the steering column and address unwanted steering wheel vibration originating from the road surface. In comparison to conventional hardy disc decouplers, they provide a better isolation in all driving situations and are lighter, more compact and sustain their isolation characteristics throughout the whole vehicle lifetime.
The compact shape provides design space and allows an elastomer layer around the aluminum core, thereby providing low axial stiffness, which means high isolation in push and pull directions. In contrast, radial stiffness is high so as to provide a direct steering feel and ensure the vehicle’s optimized handling. Small vibrations from the road are isolated to avoid constant shaking of the steering wheel.
In addition to reducing vibration, steering column bushings allow progressive damping characteristics, which are important for a more direct steering feel and control. This progression can be precisely tuned by elastomer geometry and the integrated stopper system.
