Abstract
A handwheel actuator for a steer by wire system may include a compressive loading assembly, a feedback actuator and a column for operably coupling a handwheel to the handwheel actuator. The column may operably couple a handwheel to the handwheel actuator. The column may include a column shaft extending from a first end of the column to a second end of the column. The feedback actuator may be operably coupled to the second end of the column. The feedback actuator may provide tactile feedback to an operator responsive to movement of the handwheel. The feedback actuator may include a torsion bar substantially coaxial with the column shaft. The compressive loading assembly may be disposed at the second end of the column to operably couple the column shaft and the torsion bar under a compressive load when the column is joined to the feedback actuator.
