  • Patent number: 7168879
    Abstract: A plug-in coupling for removably interconnecting a first structural member and a second structural member comprises a resiliently deformable female coupling part adapted to be inserted into a socket at the first structural member such that it is retained therein. The female coupling part comprises a ball-shaped cup, an intermediate annular wall integral with said ball-shaped cup and serving as a guide portion, and a tubular external wall integral with said annular intermediate wall. The external wall surrounds at least a part of the ball-shaped cup in spaced relation thereto and engages a peripheral wall of the socket when the female coupling part is inserted into the socket. A male coupling part comprises a ball-shaped head and a fixing portion for securing the male coupling part to the second structural member. The intermediate annular wall of the female coupling part is of an undulated shape at least in a certain area thereof.

  • Patent number: 7125513
    Abstract: A process for controlling the shrinkage behavior during the original shaping of plastics during the manufacture of a plastic shell, especially a bearing shell for a ball-and-socket joint, wherein liquefied plastic is introduced between an inner mold (3) and an outer mold (2) in order to be cured therein, wherein the plastic is partially fixed on the outer mold (2) during the curing. This process can be preferably used in a device for controlling the shrinkage behavior during the original shaping of plastics, which has a casting mold, which accommodates at least one outer mold (2) and an inner mold (3) inserted into same, wherein the liquefied plastic (1) to be molded can be introduced between the mold parts (2, 3), wherein means for fixing the liquid plastic (1) are formed on the outer mold (2).

  • Patent number: 7073970
    Abstract: A ball-and-socket joint for a motor vehicle, especially for a rocker pendulum of a motor vehicle, is provided with a housing (1), which is open on at least one side and into the interior space (2) of which a bearing shell (3) is inserted, which in turn accommodates a joint ball (4) of a ball pivot (5) in a slidingly movable manner. The interior space (2) has elevations and/or depressions (7) along its inner jacket surface (6) or a polygonal cross section, so that the bearing shell (3), which is provided with an oversize in relation to the inner jacket surface (6), can be inserted into the housing (1) in a positive-locking manner while its outer surface undergoes a partial plastic deformation. The inner jacket surface (6) may have pressure zones (19) which shorten the effective length of the elevations and/or depressions (7).

  • Patent number: 7004665
    Abstract: A low insertion force snap together automotive coupler for the suspension of a vehicle includes a spherical bearing insert having a first end, a second end, a pocket adapted to engage a ball stud that is integrally formed onto a suspension component, and an axially extending annular flange. The coupler further includes a receiver adapted to receive the spherical bearing insert after the spherical bearing insert has been placed to a ball stud and to engage the flange to secure the spherical bearing insert within the receiver. The pocket within the spherical bearing insert is shaped such that an axial force tending to pull the ball stud out of the pocket will result in a radial force exerted upon the flange, thereby causing additional force to keep the flange engaged within the receiver.

  • Patent number: 6945682
    Abstract: A headlight for motor vehicles is provided that includes an optical element, which is connected to a support element by at least one ball-and-socket joint. The ball-and-socket joint has a spherical ball and a spherical socket. The socket encloses the ball with socket segments and is inserted together with the ball into a receptacle, and contacts, via its socket segments, the inside of the receptacle. The socket contacts the bottom of the receptacle with a base, and has on the other side freestanding elastic socket segments that enclose the ball. Elastic detent elements of the receptacle engage behind the base of the socket and retain the socket axially in the receptacle.

  • Patent number: 6866441
    Abstract: In a ball joint including a retaining ring to which a boot is mounted and which is press-fitted to a ball stud, the ball stud is formed with a press-fit portion to which a cylindrical portion of the retaining ring is press-fitted, and an annular projection having a tapered forming face rising with an up-grade from a press-fit terminal end of the press-fit portion. When the cylindrical portion is press-fitted to the press-fit portion, a particular cylindrical portion set at a tip end of the cylindrical portion is expanded by pressing the particular cylindrical portion against the tapered forming face, thereby forming a small flange. Thus, the small flange of the retaining ring can be simultaneously formed utilizing a force of press-fitting of the cylindrical portion of the retaining ring to the ball stud. This can contribute to a reduction in the number of assembling steps.

  • Patent number: 6742955
    Abstract: A tie rod end having a purgative zerk for removal of used lubricants is provided. In one embodiment of the invention, the tie rod end includes a socket member that defines a first bore in which a ball stud member is disposed and a second bore in communication with the first bore. The purgative zerk is disposed in the second bore. In a second embodiment of the invention, the purgative zerk is disposed in a plug used to close one end of the first bore. The use and location of the purgative zerk enable purge holes to be eliminated from a boot seal disposed at one end of the first bore thereby reducing contamination of the tie rod end.
