摘要： A torsion bar is provided that is easy, quick, and cost effective to manufacture. The torsion bar may extend along an axis and have a first end and a second end that is spaced from the first end. The torsion bar may have an active section positioned between the first and second ends. The active section may also have a length defined along the axis. A cross-section transverse to the axis may define a contour of the torsion bar where the contour may be uniform along the length of the active section. The contour may define at least one of a polygon and a polygon-like shape.

摘要： A position measurement system for a steering system includes a steering shaft. The position measurement system also includes a worm gear coupled to the steering shaft. The position measurement system further includes a worm in meshed engagement with the worm gear, the worm driven by a motor. The position measurement system yet further includes a first sensor operatively coupled to the worm to detect an angular position of the worm and the motor that drives the worm. The position measurement system also includes a driving gear coupled to the steering shaft. The position measurement system further includes a spur gear in meshed engagement with the driving gear. The position measurement system yet further includes a second sensor operatively coupled to the spur gear to detect an angular position of the spur gear.

摘要： A power steering system including a first linkage arm pivotally coupled to a cross-link member extending in a transverse direction. Also included is a first shaft generally orthogonal to the first linkage arm, the first shaft configured to rotate the first linkage arm. Further included is a power portion of the first linkage arm extending from a first end of the first linkage arm to the first shaft. Yet further included is an assist portion of the first linkage arm extending from the first shaft to a second end of the first linkage arm. Also included is an electric actuator. Further included is a linkage member extending from the electric actuator and operatively coupled to the assist portion of the first linkage arm.

摘要： A human exoskeleton includes a power source. The human exoskeleton also includes a controller configured to activate power between the exoskeleton and the power source. The human exoskeleton further includes a power disconnect mechanism electronically connected to the controller and configured to disconnect power between the exoskeleton and the power source when activated, the power disconnect mechanism activated when a pressure applied to the power disconnect mechanism is above a range programmed in the controller or below the range programmed in the controller, the human exoskeleton powered only when the pressure applied to the power disconnect mechanism is within the range programmed in the controller.

摘要： A steer-by-wire steering system for a vehicle includes a rack moveable in an axial direction. The steer-by-wire steering system also includes an anti-rotation device disposed proximate an outer surface of the rack. The anti-rotation device includes a yoke having a bearing journal extending therefrom. The anti-rotation device also includes a bearing disposed on the bearing journal. The anti-rotation device further includes a running surface disposed within a rack housing and extending in a longitudinal direction of the rack, wherein the bearing is positioned to move along the running surface during operation.

摘要： A steering column assembly includes a steering column shaft having a first end and a second end. The steering column assembly also includes an intermediate shaft coupled to the steering column shaft first end. The steering column assembly further includes a steering input pinion coupled to the intermediate shaft. The steering column assembly yet further includes a counter rotation mechanism causing a non-rotational condition of at least a portion of the steering shaft via counter rotational movement of the steering column assembly during rotation of the steering input pinion.
