  • Patent number: 7494440
    Abstract: A steering wheel mounting assembly comprising a stationary support carrier, first and second drive rings, and a drive roller assembly. The stationary support carrier defines first and second ring receiving areas. The first drive ring has a first cylindrical raceway, is supported in the first ring receiving area, and is adapted for connection to a steering wheel. The second drive ring has a second cylindrical raceway, is positioned in the second ring receiving area, and is adapted for connection to a steering shaft. The drive roller assembly is supported within the first and second cylindrical raceways and comprises first and second roller planets, a sun roller supported in frictional engagement with the first and second roller planets, a first loading planet frictionally positioned between the sun roller and the first cylindrical raceway, and a second loading planet frictionally positioned between the sun roller and the second cylindrical raceway.

  • Publication number: 20080236328
    Abstract: 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.

  • Patent number: 5259677
    Abstract: A bearing assembly is mounted on an eccentric sleeve having a bore for receiving a rotatable shaft. After the bearing assembly is mounted on the eccentric sleeve, a counterweight lobe is mounted on the eccentric sleeve, abutting the bearing assembly, to control dynamic balance of the bearing and sleeve assembly and to restrain movement of the bearing assembly along the axis of the bore. The eccentric sleeve and counterweight lobe are keyed together to prevent relative rotation therebetween.
