A ball-and-socket joint ( ) is provided with a housing ( ) closed by a cover ( ), with a bearing shell ( ) and a joint ball ( ) accommodated therein rotatably and tiltably with a ball pivot. The bearing shell ( ) provided with projections and offsets on its outside as well as an entropy-elastic, pretensioned spring element ( ) are fixed by the cover ( ) in the housing ( ). The bearing shell is formed by lower and upper bearing shells ( ), both of which are closed, and the lower bearing shell ( ) extending partially over the upper bearing shell ( ) is provided on its overarching inside ( ) and the upper bearing shell ( ) is provided on its outside ( ) with the projections and offsets ( ) with which the entropy-elastic spring element ( ) cooperates in a positive-locking and/or non-positive manner under the action of the cover ( ) in its closed position and nonrotatably couples the two bearing shells ( ) with one another.

Ball joint

A joint housing ( ) has a housing recess ( ), a pivot pin ( ), mounted in the housing recess. The pivot pin has a joint ball ( ) provided with a surface protection. A pin section protrudes from a housing opening ( ), with a bearing shell ( ) arranged between the joint housing and the joint ball, and with a closing ring ( ), which closes the housing recess of the joint housing and tensions the bearing shell arranged therein in the joint housing. The closing ring follows essentially with its inner contour the outer contour of the bearing shell due to a bevel or a radius formed. The closing ring ( ) to be inserted into the joint housing is fixed in its position in the joint housing ( ) and has a sealing lip ( ) which is in contact with the joint ball ( ) under elastic pretension on the side of the housing opening ( ) through which the pin section of the pivot pin ( ) protrudes from the joint housing ( ).

A ball-and-socket joint is provided with a joint housing which is open on at least one side with a housing recess, with a joint pin mounted in the housing recess with its joint ball provided with a surface protection. A pin section projects from a housing opening. A bearing shell is arranged between the joint housing and the joint ball. A sealing bellows is provided between the joint housing and the joint pin. A sealing element, which is under elastic pretension in sliding contact with the joint ball, is arranged between the joint housing and the joint ball.

Ball-and-socket joint

A ball-and-socket joint preferably for vehicle suspensions or steerings of motor vehicles with a joint housing, with a housing cover closing the joint housing on one side, and with a pivot pin, which is mounted rotatably and deflectably in at least one bearing shell using a spherical bearing surface, is described. The bearing shell is in turn stationarily fixed in the joint housing and an elastic buffer element (,) is arranged on the outside of the joint housing (,) facing away from the pivot pin (,).
