A ball-and-socket joint, preferably for vehicle suspensions or steering mechanisms of motor vehicles, with a joint housing, a pivot pin (1), which comprises a spherical surface (3) and a pin part (2) and is mounted with the spherical surface rotatably and deflectably in the joint housing (5) and is fixed with the pin part (2) on a mount (7) provided on the chassis, and with an elastic sealing bellows (8), which is fixed statically at the joint housing (5) and by means of at least one sealing seat at the pin part (2), is presented, in which the sealing seat has according to the present invention an elastic sealing ring (11) that is directly in contact with the pin part (2) under pretension or is connected to same in substance between the sealing bellows (8) and the pin part (2) and an annular sleeve (13) arranged between the sealing bellows (8) and the sealing ring (11). Optimal coordination of the sealing components (annular sleeve and sealing ring) that perform relative movements in relation to one another can be achieved due to the design according to the present invention, so that corrosion problems known from the state of the art are eliminated at the partition line of the seal. |
