Abstract:
A steering column jacket assembly for a steering system of motor vehicle includes a first steering jacket extending along a longitudinal axis and a second steering jacket arranged for telescoping movement relative to the first steering jacket along the longitudinal axis. A guide bracket is fixed to the second steering jacket. The guide bracket has a guide bushing disposed between the guide bracket and the first steering jacket, the guide bushing self-centering the first steering jacket and the second steering jacket relative to one another to inhibit relative rotation between the first steering jacket and the second steering jacket.
Abstract:
An axially adjustable steering column assembly includes an upper jacket and a lower jacket, wherein the lower jacket defines a pair of tapered rail slots, each of the tapered rail slots disposed on opposite sides of the lower jacket. The steering column assembly further includes a column mounting bracket, wherein the lower jacket is operatively coupled to the column mounting bracket and translates relative to the column mounting bracket. The steering column assembly yet further includes a first pair of sliding wedge bushings, each disposed within a respective one of the pair of tapered rail slots. The steering column assembly also includes a first bolt, extending through the first pair of sliding wedge bushings and operatively coupling the first pair of sliding wedge bushings to the lower jacket.
Abstract:
A method of assembling a steering column assembly includes pressing a first pivot bushing into a first rake bracket first opening of a first rake bracket and inserting a first pivot fastener into the first pivot bushing and into a first mounting bracket opening of a first mounting bracket arm of a mounting bracket. The method further includes displacing material of the first mounting bracket arm with first splines of the first pivot fastener to form first mating splines within the first mounting bracket opening.
Abstract:
A steering column assembly includes a steering column housing. The steering column assembly also includes a lower shaft disposed within the steering column housing and axially adjustable. The steering column assembly further includes a torque adjustment assembly operatively connected to the lower shaft to increase or decrease a steering shaft turning torque.

Abstract:
A bushing assembly for a steering column having a fixed jacket and a telescope jacket is provided having a set screw configured for insertion into the fixed jacket, and a radial telescope bushing co-acting with the set screw and having a post and a curved bushing portion configured to pre-load the radial telescope bushing against the telescope jacket to provide a lash-free interface between the fixed jacket and the telescope jacket.
Abstract:
A self-de-lashing power-rake mechanism of an adjustable steering column assembly of a vehicle is provided. The power-rake mechanism includes a jacket, rake bracket coupled to the jacket, and rake bolt extending through the jacket and bracket. At least one pivot bushing is disposed between the jacket and bracket and configured to receive and radially constrict around the bolt. A fastener is configured to be positioned onto the bolt, tightened, and seated on the bracket. The bolt is forced through the fastener, bracket, bushing, and jacket. The bolt is seated on the bracket as the fastener is tightened and draws the bolt, fastener, bracket, bushing, and jacket together as the fastener is being seated on the bracket, thereby de-lashing respective interfaces defined between and among the bolt, fastener, bracket, bushing, and jacket. A steering column assembly including the mechanism is also provided.
Abstract:
A steering column for a vehicle having an anti-rotation feature is provided. The steering column includes a lower jacket and an upper jacket configured for telescopic movement relative to the lower jacket. A telescope drive bracket is coupled to the upper jacket. A telescope actuator is operably coupled to the telescope drive bracket and configured to telescopically move the upper jacket relative to the lower jacket.
Abstract:
A steer-by-wire steering column includes a single column jacket extending in a longitudinal direction. The steering column also includes a single steering shaft extending in the longitudinal direction and housed at least partially within the single column jacket. The steering column further includes a steer-by-wire electric actuator at least partially disposed within the single column jacket and surrounding the single steering shaft to provide resistance to the single steering shaft.
Abstract:
An axially adjustable steering column assembly includes an upper jacket. The assembly also includes a lower jacket, wherein the upper jacket is received within the lower jacket and is telecopingly adjustable therein, the lower jacket having a position sensor operatively coupled thereto. The assembly further includes a column mounting bracket, wherein the lower jacket translates and rotates relative to the column mounting bracket. The assembly yet further includes a geared rack operatively coupled to the column mounting bracket, the geared rack correspondingly rotatable with the lower jacket, wherein the geared rack is in contact with a gear wheel of the position sensor to detect the axial position of the axially adjustable steering column assembly.
