Ball and socket joint

Abstract

A ball and socket joint for a motor vehicle, especially for the chassis of the motor vehicle, has a ball and socket joint housing (1), which has a joint opening and in which a bearing shell (5) made of an insulating material is arranged. A ball pivot (4), which is made of an electrically conductive material, has a joint ball (2) and a pivot (3), and which is mounted with its joint ball (2) rotatably and pivotably in the bearing shell (5) and projects from the ball and socket joint housing with its pivot (3) through the opening of the joint. An electrode (14) is arranged in the wall of the bearing shell (5) at a distance (Δ) from the joint ball (2), and the electrode (14) and the joint ball (2) are electrically insulated against each other via the bearing shell (5). Furthermore, between the joint ball (2) and the ball and socket joint housing (1), the wall has at least two layers (12, 13) arranged one after another, between which the electrode (14) is arranged.
