A device for assembling a column tube in an adjustable steering column assembly, comprising a spacer portion adapted to provide rotational damping; provide damping during adjustment of the steering column assembly (e.g., telescope adjustment); and assist in centering the column tube when in an unlocked position and assist in resisting lash. The device may further comprise a stop bracket portion adapted to limit rotational travel of the column tube when in an unlocked position; and retain the column tube longitudinally within the steering column assembly.

A steering system includes a rotary shaft to which an operation member is coupled; a first actuator; a second actuator; a control unit; and a moving unit configured to move the operation member between a normal position and a storage area. The control unit is configured to switch between a manual drive mode and an autonomous drive mode. The control unit is configured to, when moving the operation member from the storage area to the normal position, start synchronous control when the operation member satisfies a predetermined condition before the operation member reaches the normal position, the synchronous control being control in which the control unit controls the first actuator to change a rotation angle of the rotary shaft to an angle corresponding to a steered angle of steered wheels driven by the second actuator.

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.

A steering column assembly includes a lower jacket. The steering column assembly also includes an upper jacket in telescoping engagement with the lower jacket. The steering column assembly further includes an energy absorbing strap assembly operatively coupled to the upper jacket. The energy absorbing strap assembly includes a strap having a stationary leg and a moveable leg, the moveable leg extending from a first strap end region to a curved portion, the stationary leg extending from the curved portion to a second strap end region, wherein the second strap end region forms a U-shape defined by a radially outer segment, a radially inner segment and a connecting segment to join the radially outer segment and the radially inner segment. The energy absorbing strap assembly also includes a pin extending through the radially inner segment of the stationary leg and the moveable leg.

An intermediate shaft assembly for a steering column is disclosed herein. The assembly includes a first shaft defining a cavity and a first bearing raceway, a second shaft arranged at least partially within the cavity of the first shaft, a sleeve arranged on an axial end of the second shaft and defining a second bearing raceway, and a bearing assembly including at least two rows of rolling elements and a cage. The rolling elements are supported between the first bearing raceway of the first shaft and the second bearing raceway of the sleeve. The sleeve can be heat treated, and formed from sheet metal. The sleeve can be secured to the axial end of the second shaft by a direct rotational connection such that the sleeve is rotationally fixed to the second shaft.

A locking mechanism for a telescoping steering column includes an energy absorption strap having a plurality of teeth disposed therealong. Also included is a clamp bolt rotatably driven by an adjustment lever. Further included is an actuator body coupled to the clamp bolt and rotated therewith. Yet further included is a first lock cam coupled to the actuator body and engageable with the teeth of the energy absorption strap to lock the telescoping steering column in a first direction. Also included is a second lock cam coupled to the actuator body and engageable with the teeth of the energy absorption strap to lock the telescoping steering column in a second direction different than the first direction.
