Abstract
A handwheel actuator for a steer by wire system may include a feedback actuator and a column for operably coupling a handwheel to the handwheel actuator. The column includes a column shaft extending from a first end of the column to a second end of the column. The feedback actuator is operably coupled to the second end of the column and provides tactile feedback to an operator responsive to movement of the handwheel. The feedback actuator includes a torsion bar coaxial with the column shaft. The column shaft is supported relative to a housing of the column by a first column shaft bearing disposed proximate to the first end of the column and a second column shaft bearing disposed proximate to the second end of the column. The torsion bar extends into the column shaft past the second column shaft bearing and is operably coupled to the column shaft via a removable fastener disposed at a portion of the torsion bar that extends past the second column shaft bearing.
