  • 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: 6308959
    Abstract: An elastic sealing element in the form of bellows, which is used to seal the contact surface between at least two components movable in relation to one another is described, which has low-elasticity contact zones as well as a deformation zone whose elasticity is higher than that of the contact zones, wherein the said deformation zone defines a chamber for accommodating lubricants on its inner side facing the movable components. An overpressure relief means (14) is arranged at least in the area of one of the two low-elasticity contact zones (6 or 7). The overpressure relief means (14) has at least one relief opening (15) connecting the lubricant chamber (11) with the outside of the sealing element (1) and a closing element (16) covering the said relief opening. The closing element (16) is in turn made in one piece with the sealing element (1) and closes the relief opening (15) up to an overpressure limit in the lubricant chamber (11) due to the intrinsic elasticity of the material of the sealing element.
