Abstract
A vehicle steering system is provided that includes a bar with threads and an anti-rotation section. An actuator having a ball nut configured to engage the threads of the bar such that the rotation of the ball nut moves the bar longitudinally along a bar axis to move one or more wheels of a vehicle. A sleeve is disposed on the anti-rotation section of the bar and non-rotatably engages the threads of the bar such that the bar is prevented from rotating about the bar axis.
Claims20
A vehicle steering system comprising:
- a bar having threads and an anti-rotation section, the bar configured to move at least one wheel;
- an actuator having a threaded nut configured to engage the threads of the bar such that rotation of the threaded nut moves the bar longitudinally along an actuation axis via the threads;
- and
- a sleeve disposed on the anti-rotation section and configured to non-rotatably engage the threads of the bar such that the bar is prevented from rotating about the actuation axis.

A vehicle steering system comprising:
- a bar having threads, the bar configured to move at least one wheel;
- an actuator having a threaded nut configured to engage the threads of the bar such that rotation of the threaded nut moves the bar longitudinally along an actuation axis via the threads;
- and
- a sleeve disposed on the bar and configured to non-rotatably grasp the threads of the bar such that the bar is prevented from rotating about the actuation axis.
1 more element
A vehicle steering system comprising:
- a bar having threads and an anti-rotation section that interrupts the threads such that the threads extend from each side of the anti-rotation section, the bar configured to move at least one wheel;
- an actuator having a threaded nut configured to engage the threads of the bar such that rotation of the threaded nut moves the bar longitudinally along an actuation axis via the threads;
- and
- a sleeve having a bore, and the anti-rotation section and a portion of the threads are disposed within the bore, and the bore cooperates with the threads to prevent rotation of the bar about the actuation axis.
