Steering columns transmit rotational steering input from the steering wheel to the steering gear. Positioned within the vehicle cabin, they incorporate a multi-position ignition switch, tilt/telescopic adjustment mechanisms, and often, integrated turn signal controls. Columns utilize universal joints and intermediate shafts to navigate around footwells and maintain driver alignment. Modern designs frequently feature collapsible sections for energy absorption during frontal impacts, enhancing occupant safety. Splined shafts and secure mounting brackets ensure precise connection and structural rigidity throughout the steering system.
