  • Patent number: 11149783
    Abstract: A tolerance absorbing spacer for controlling manufacturing dimensional tolerance variation in products made with multiple internal components, each requiring unique dimensional tolerance allowance. This component adjusts and compensates for the resulting overall cumulative component height variation within an assembly of components, sometimes referred to as “stack height” by compensating for the maximum to minimum range of possible assembly heights, compressing and yielding under applied external force until all excess internal clearance is removed, except for a small, and desirable remaining clearance. This component yields and becomes essentially fully plastic, to provide the necessary tolerance adjustment feature only after reaching a predetermined, minimum force which exceeds all applied forces the component could reasonably encounter in service use and below which, the tolerance absorbing spacer remains fully rigid.

  • Patent number: 10309449
    Abstract: A ball joint assembly includes a ball stud, a cylindrical bearing, a housing and a retainer. The bearing has an upper end, a lower end, a exterior sidewall, an upper flange located between the upper end and a ring groove formed in the exterior sidewall, a lower flange proximate the lower end and extending outwardly and a socket cavity that opens toward the lower end. A ball portion of the ball stud is retained within the socket cavity. The bearing is secured within a bore within the housing by virtue of the working of the lower flange and the upper flange and retainer located in the ring groove. The ball joint assembly is able to resist a pull-out force of up to 1200 lbs. It may also be sealed by incorporation of a dust boot which extends between the housing and a stud portion of the ball stud.

  • Patent number: 8342769
    Abstract: A pivot socket includes a housing with an inner surface providing a cavity extending between a substantially closed end and an open end. A cartridge bearing is received in the cavity with a spring disposed between the closed end and the cartridge bearing. The cartridge bearing has an inner surface with a cylindrical portion and conical portion converging inwardly from the cylindrical portion. The cylindrical portion houses a tapered bearing for relative axial movement therewith. A stud having opposite first and second tapered surfaces diverging away from one another is received in the cartridge bearing, with the first tapered surface engaging the tapered bearing for relative sliding movement therewith and the second tapered surface engaging the conical portion of the cartridge bearing for relative sliding movement therewith, thereby causing the relative axial movement between the tapered bearing and the cartridge bearing.

  • Patent number: 7837407
    Abstract: A ball joint assembly for a vehicular steering or suspension application includes a cap-like housing in which is captured the articulating ball portion of a stud. A shank extends from the ball portion, outwardly from the housing cap, to provide a connection and anchoring interface for the suspension member or other anchoring component. The connection interface with the anchoring suspension member is characterized by a specially designed surface which is convenient to machine, provides increased surface-to-surface contact area, and provides additional advantages such as improved stress distribution and NVH benefits. A washer-like cone adaptor mates with a specially formed adaptor interface region on the stud. On its outer surface, the adaptor has a broad tapering feature designed to seat in a complementary-shaped receiving flare in the anchoring suspension member.

  • Patent number: 7600940
    Abstract: A ball joint includes a housing extending between open and closed ends. The housing has a cavity with a cylindrical wall extending from adjacent the closed end to an annular flange adjacent the open end. A stud extends into the cavity. An inner bearing element has a bore configured to slide relative to the stud and an outer bearing surface. An outer bearing element is configured to slide relative to the housing and has an inner bearing surface for pivotal movement with the inner bearing element outer bearing surface. An annular cup is disposed between the closed end of the housing and the outer bearing element. The cup can slide relative to the housing and has a bore allowing axial movement of the stud. A spring member imparts an axial bias force on the cup and imparts a preload between the outer bearing element and the inner bearing element.

  • Patent number: 6676325
    Abstract: A pivot socket of the present invention incorporates a stud shaft component having a tapered head portion disposed within a housing cavity, and an axial pin extension extending upward into the cavity therefrom. The tapered head portion seats against a tapered bearing surface disposed within the housing cavity, and the axial pin extension is enclosed within a resilient bushing. During use, lateral and axial loads imparted on the stud shaft are transformed into radial and axial component forces at the bearing surfaces. Angulation loads are resisted by the tapered head portion, and converted to axial forces. The radial force components are distributed to the interior walls of the housing cavity, while the axial force components are transferred axially through the resilient bushing to the end closure components secured to the housing, or directly to the housing through the tapered bearing surface.

  • Patent number: 6454484
    Abstract: A pivot socket of the present invention incorporates a stud shaft component having a lower part-spherical head portion disposed within a housing cavity, and an axial pin extension extending upward into the cavity therefrom. The lower part-spherical head portion seats against a partial spherical bearing surface disposed within the housing cavity, and the axial pin extension is enclosed within a corrugated or crinkled coil compliance bearing formed from sheet steel. During use, lateral and axial loads imparted on the stud shaft are transformed into radial and axial component forces at the partial spherical bearing surface and the corrugated or crinkled coil compliance bearing. The radial force components are distributed to the interior walls of the housing cavity, while the axial force components are transferred axially through the corrugated or crinkled coil compliance bearing to the end closure components secured to the housing.

  • Patent number: 6439794
    Abstract: A pivot socket of the present invention incorporates a stud shaft component having a partially spherical head portion disposed within a housing cavity, and an axial pin extension extending upward into the cavity therefrom. The partially spherical head portion seats against a partial spherical bearing surface disposed within the housing cavity, and the axial pin extension is enclosed within a resilient cushion. A Belleville washer is interposed between the resilient cushion and the partial spherical bearing surface. During use, lateral and axial loads imparted on the stud shaft are transformed into radial and axial component forces at the bearing surfaces. The radial force components are distributed to the interior walls of the housing cavity, while the axial force components are transferred axially through the resilient cushion to the end closure components secured to the housing.

  • Patent number: 6367243
    Abstract: A method and system are provided for propelling an aerodynamic vehicle into space. The aerodynamic vehicle uses a nuclear-based thermal rocket (NTR) propulsion system capable of producing a hydrogen exhaust. A flow of air is introduced into the hydrogen exhaust to augment the thrust force at speeds of the vehicle up to approximately Mach 6. When the speed of the vehicle is approximately Mach 6 and the altitude of the vehicle is approximately 40 kilometers, the flow of air is stopped and the vehicle is propelled into space using only the NTR.
