A ball-and-socket joint, preferably for chassis suspensions and/or steering mechanisms of motor vehicles, is presented, which has a ball pivot pin (1), which is accommodated rotatably and tiltably in a joint housing (8) with one of its free ends with a spherical joint area (3). The other free end of the ball pivot pin (1) is fixed to a body part. The ball-and-socket joint has a stop device for limiting the tilting movement of the ball pivot pin (1) in the joint housing (8), which comprises a stop element, which is arranged in the bottom area (11) of the joint housing (8) rotationally symmetrically to the longitudinal axis of the sphere and cooperates with the end-side joint area (6) of the ball pivot pin (1). Corresponding to a first embodiment variant, the ball-and-socket joint has an arch projecting spherically over the bottom area ( 11) of the joint housing (8) as a stop element; a second solution variant provides for the stop element in the bottom area ( 11) of the joint housing (8) to have a hollow spherical shape, the radius of the hollow spherical shape being greater than the radius of the spherical shape of the joint area of the ball pivot pin (1).

The invention claimed is: 1. A ball-and-socket joint, for chassis suspensions and/or steering mechanisms of motor vehicles, the ball-and-socket joint comprising: a joint housing defining an open end and with a single part forming side walls and defining an integral closed bottom area; a pivot pin accommodated rotatably and tiltably in said joint housing with a joint area at one free end, said joint area having an essentially spherical shape with a flattened area end face, said flattened area being planar and not forming a recess in said joint area, said pivot pin being fixed statically to a body part with a pin connection area located at another free end; and a stop device for limiting the tilting movement of said pivot pin unitarily and rigidly formed with said housing, said stop device having a stop element arranged rotationally symmetrically to the longitudinal axis of the ball-and-socket joint with said stop element formed by said bottom area of said joint housing and cooperating with said flattened area of said pivot pin, said stop element comprising a rotationally symmetrical arch with a constant radius ball surface form projecting spherically, in a direction of said flattened area, over said bottom area of the joint housing. 2. A ball-and-socket joint according to claim 1, wherein said rotationally symmetrical arch with a ball surface has an arch ball surface center and said joint area having an essentially spherical shape has a ball joint center, said ball joint center being on an opposite side of said arch from said ball surface center. 3. A ball-and-socket joint according to claim 1, wherein said pivot pin may be pivoted between a non-inclined position and a fully inclined position in which said stop element is in contact with said flattened area and wherein said stop element is not in contact with said flattened area in said non-inclined position of said pivot pin. 4. A ball-and-socket joint according to claim 3, wherein said flattened area is perpendicular to a longitudinal axis of said pivot pin. 5. A ball-and-socket joint according to claim 4, wherein said flattened area faces said rotationally symmetrical arch. 6. A ball-and-socket joint according to claim 4, wherein said ball surface form is made in one piece with the joint housing. 7. A ball-and-socket joint according to claim 4, wherein said rotationally symmetrical arch has an arch apex arranged on the longitudinal axis of said ball and socket joint. 8. A ball-and-socket joint, for chassis suspensions and/or steering mechanisms of motor vehicles, the ball-and-socket joint comprising: a joint housing with a closed bottom area; a pivot pin accommodated rotatably and tiltably in said joint housing with a joint area at one free end and a pin area extending to an opposite free end, said joint area having a substantially spherical shape except for a flat region at an end side and a pin connection to said pin area located opposite said end side, said spherical shape having a constant radius from a pivot center, said flat region being perpendicular to a direction of extension of said pin area; and a stop device for limiting the tilting movement of said pivot pin in said housing, said stop device having a stop element-arranged rotationally symmetrically to the longitudinal axis of the ball-and-socket joint defined by said bottom area of said joint housing and cooperating with said end side joint area of said pivot pin, said stop element in said bottom area of said joint housing having a hollow spherical shape surface with a constant radius of said hollow spherical shape surface being greater than said radius of the spherical shape of said joint area of said pivot pin, said hollow spherical shape surface having a hollow shape surface center, said hollow shape surface center and said pivot center of said joint area being on a same side of said hollow spherical shape surface. 9. A ball-and-socket joint, for chassis suspensions and/or steering mechanisms of motor vehicles, the ball-and-socket joint comprising: a joint housing; a pivot pin accommodated rotatably and tiltably in said joint housing with a joint area at one free end, and a pin connection located at another free end; and a stop device for limiting the tilting movement of said pivot pin in said housing, said stop device having a stop element-arranged rotationally symmetrically to the longitudinal axis of the ball-and-socket joint in a bottom area of said joint housing and cooperating with said joint area of said pivot pin, said stop element in said bottom area of said joint housing having a hollow spherical shape surface of a constant radius, said constant radius of said hollow spherical shape surface being greater than a radius of a spherical shape of said joint area of said pivot pin, said hollow spherical shape having a hollow shape center located on a joint area side of said hollow spherical shape surface, said joint area having an essentially spherical shape with a flattened area and said flattened area faces the hollow spherical shape surface. 10. A ball-and-socket joint according to claim 9, wherein said hollow spherical shape surface is made in one piece with said joint housing. 11. A ball-and-socket joint according to claim 9, wherein said flattened area is perpendicular to a longitudinal axis of said pivot pin. 12. A ball-and-socket joint according to claim 9, wherein said stop element form is made in one piece with the joint housing. 13. A ball-and-socket joint according to claim 9, wherein said hollow spherical shape surface has a spherical shape surface apex arranged on the longitudinal axis of said ball and socket joint. 14. A ball-and-socket joint according to claim 9, wherein said pivot pin may be pivoted between a non-inclined position and a fully inclined position in which said stop area is in contact with said flattened area and wherein said stop area is not in contact with said flattened area in said non-inclined position of said pivot pin.
