  • Patent number: 7578215
    Abstract: The position of a lever is adjustable relative to its bearing via a locking clip that is arranged opposite to a catch. The lever is arranged in a bearing shell with a ball therein in which the lever is arranged so as to be displaceable with the catch attached. The locking clip is guided in the walls of the ball, and the locking of the locking clip and catch in the closed state of the bearing shell forms a positive engagement. The adjustable ball bearing apparatus for shift levers and selector levers compensates for tolerances in the installation of a lever between the ball, the bearing shell, and the axis of the lever.

  • Publication number: 20090010706
    Abstract: A ball joint is provided that when a load equal to or greater than a first predetermined value is applied in the axial direction of a ball stud, if a cushion seat is deformed by a predetermined amount, an opposing surface portion contacts a first load receiving portion of a ball seat, preventing the cushion seat from being deformed by a predetermined amount in the central axis direction. When a load equal to or greater than a second predetermined value greater than the first is applied in the axial direction of the ball stud, a second load receiving portion of the ball seat contacts a bottom surface portion of an inner chamber of a socket, whereby an axial load onto the cushion seat is reduced, and the ball seat prevents the cushion seat from being deformed by a predetermined amount or more in the axial direction.

  • Publication number: 20080089738
    Abstract: In a ball joint 10, when a ball stud 11 rotates about its center axis L, at the beginning of the rotation, a ball seat 12 can be elastically deformed in the rotational direction, whereby the rotational torque can be gradually increased as the rotational angle increases. In a region of the ball seat 12 where slits S are provided, the frictional engagement force between a spherical head portion 11a of the ball stud 11 and the ball seat 12 is made greater than the frictional engagement force between the ball seat 12 and the ball socket 13. Therefore, when the ball stud 11 rotates about its center axis L, the ball seat 12 elastically deforms in the rotational direction before the spherical head portion 11a starts to slip in relation to the ball seat 12 in the region where a lager fiction engagement force is generated.

  • Patent number: 7357590
    Abstract: A ball-and-socket joint, for example for use with an articulated support in an automobile, includes an essentially ring-shaped or cup-shaped joint housing and a bearing shell disposed in an interior space of the joint housing. The ball of a ball pin is slidingly received in the bearing shell. The inside contour of the joint housing and the outside contour of the bearing shell are essentially shaped as a truncated cone. The bearing shell can be essentially freely positioned in the joint housing in an axial direction of the ball pin. The position at which the bearing shell is anchored in the joint housing can then be precisely and reproducibly adjusted by way of the truncated conical surfaces. The service life, robustness and quality of ball-and-socket joints can be significantly improved during manufacture, while simplifying their fabrication and reducing their manufacturing cost.
