Steer-by-Wire Jacket Axis Skewing Assembly for Collapse Performance

The column jacket is intentionally designed with an asymmetric, skewed configuration where the longitudinal axis is oriented at a non-parallel angle relative to the hand wheel actuator central axis. This asymmetric geometry is deliberately introduced to reduce friction during collapse and enhance energy absorption performance, accepting the trade-off of increased manufacturing complexity.

The patent applies parameter changes by altering the angular orientation parameter of the column jacket from a standard parallel alignment to a specific non-parallel angle. This parameter modification optimizes the mechanical interaction between the jacket and hand wheel actuator, reducing friction and improving collapse characteristics while requiring updated manufacturing processes.

The skewed configuration of the column jacket creates an asymmetric mechanical system that enhances energy absorption during collapse. The non-parallel orientation allows for more effective energy dissipation through reduced friction and improved structural deformation characteristics, despite the increased device complexity.

The patent converts the potential harm of increased structural complexity into a benefit by strategically designing the skewed geometry to optimize energy absorption. The complex angular configuration is deliberately introduced to transform the collapse process into a more effective energy dissipation mechanism, turning what would normally be a disadvantage into a performance advantage.
