  • Patent number: 6949026
    Abstract: A housing has a longitudinally extending aperture and at least one internal, longitudinally extending groove. At least one longitudinally extending blade is mountable on the shaft and positioned within the housing such that the blade extends radially outwardly into the longitudinal groove of the housing. A cross pin extends radially through the longitudinally extending aperture of the housing for engagement with the shaft, and a resilient material is positioned between the housing and the blade, and between the cross pin and the housing, such that the blade will transmit torque to the housing with a desired radial, axial and torsional compliance.
    Type: Grant

  • Patent number: 4911034
    Abstract: A shaft slides within a tube. A relatively high-rate leaf spring is positioned to exert its force against the outer surface of the shaft. The leaf spring provides optimal sliding force between the shaft and the tube with minimum friction, while also functioning to minimize rotational lash. Indents located on the exterior surface of the tube are directed radially inward to further minimize rotational lash.

  • Patent number: 4746144
    Abstract: The breakaway vehicular steering assembly has a tube and a shaft normally operable as a unit. The tube and the shaft are held together by a shearpin which will shear at the application of a predetermined axial force.A portion of the tube is channelled; the shaft fits within the channel. A ramp extending from the walls of the tube is adapted to move the shaft outwardly from the channel after the shearpin has been broken and the shaft moved axially within the channel and along the ramp. As the shaft moves out from the channel, a metal band innerconnecting the side walls of the channel is broken at a predetermined force and alignment tabs extending outwardly from the tops of the side walls of the channel in the tube are expanded so that the shaft is completely removed from the channel.
