20080236328 | Steering Wheel Mounting Assembly - A steering wheel mounting assembly comprising first and second stationary rings, the second stationary ring being adapted for connection to a vehicle frame. The assembly further comprises a steering hub having a spindle with a radial flange extending therefrom. The spindle is adapted for connection with a steering shaft and the radial flange is adapted for connection with a steering wheel. The spindle has a first bearing raceway for engaging a bearing of the first stationary ring and a second bearing raceway for engaging a bearing of the second stationary ring. The steering hub has at least one opening that defines a bearing surface. A friction roller assembly, having a shaft with a third bearing thereabout, is positioned in the opening such that as the third bearing rotates relative to the bearing surface, the third bearing moves radially outward and the shaft engages the first and second cylindrical raceways. | 10-02-2008 |

20090127963 | ELECTRIC MOTOR WITH FIELD WEAKENING - An electric motor comprising a rotor, a stator and a field weakening device. The rotor has a plurality of magnets mounted thereto, and the stator is located adjacent to the rotor and has a plurality of slots defined therein. The slots define raised teeth and are wound with electrical wiring to generate a magnetic field when the wiring is energized with current. The field weakening device is made from a highly magnetically permeable material and a comparatively lower magnetically permeable material. The field weakening device is disposed between the rotor and the stator and is selectively movable between a first position to align the highly magnetically permeable material between the teeth of the stator and the magnets of the rotor and a second position to align the comparatively lower magnetically permeable material between the teeth of the stator and the magnets of the rotor. | 05-21-2009 |
