  • Patent number: 7832936
    Abstract: A method for delashing a shaft assembly and an assembly embodying the method are disclosed. The assembly includes a housing having a bore extending therethrough, and a shaft mounted within the bore. A shoulder extends into the bore to define a constriction along the bore. A bushing is positioned on an end of the shaft such that at least a portion of the bushing is spaced apart from the shoulder to define a cavity therebetween when the shaft is in the bore. A filler material is disposed in the cavity between the bushing and the shoulder for maintaining an axial compressive load on the shaft. In another aspect, a plug formed from a fusible material is provided. The plug includes a base portion and a plurality of channels disposed along an exterior of the base portion for enabling a flow of melted plug material along the channels.
    Type: Grant

  • Patent number: 6799780
    Abstract: A plastic honey comb mounting bracket having a center passage surrounds a mast jacket of the steering column. The top of the plastic mounting bracket is clamped flush against a flat panel on a body of the motor vehicle by a pair of spring washers supported below respective ones of a pair of platforms on the mounting bracket by a pair of rigid studs on the vehicle body. The rigid studs are exposed through a pair of vertical slots in the mounting bracket. In some embodiments the spring washers release the plastic mounting bracket for linear translation as a unit with the mast jacket with the path traversed by the mast jacket being defined by the vertical slots in the mounting bracket. In another embodiment, the plastic mounting bracket remains stationary and the path traversed by the mast jacket during its collapse stroke is defined by the center passage in the plastic mounting bracket.

  • Publication number: 20030001375
    Abstract: A mounting apparatus for an energy absorbing motor vehicle steering column including a molded structural plastic honey comb mounting bracket having a center passage around a mast jacket of the steering column. The top of the plastic mounting bracket is clamped flush against a flat panel on a body of the motor vehicle by a pair of spring washers supported below respective ones of a pair of platforms on the mounting bracket by a pair of rigid studs on the vehicle body. The rigid studs are exposed through a pair of vertical slots in the mounting bracket. In some embodiments of the mounting apparatus, the spring washers release the plastic mounting bracket for linear translation as a unit with the mast jacket through an energy absorbing collapse stroke of the latter with the path traversed by the mast jacket being defined by the vertical slots in the mounting bracket and the flat panel above the mounting bracket.
