Abstract

A ball pivot ( 3 ) of a ball and socket joint for a motor vehicle, with a pivot ( 2 ) and with a joint ball ( 1 ) connected thereto. A recess ( 12 ) with a magnet ( 13 ) arranged therein is provided in the ball pivot ( 13 ). An intermediate space ( 17 ), which is filled with a nonmagnetic material ( 16 ) for fixing the magnet ( 13 ), is formed between the jacket surface ( 14 ) of the magnet ( 13 ) and the inner wall ( 15 ) of the recess ( 12 ).

       2 . A ball pivot in accordance with  claim 1 , wherein said magnet has front sides and is directly in contact by one of said front sides with said ball pivot.  
   
   
       3 . A ball pivot in accordance with  claim 1 , wherein said magnet is cylindrical or truncated cone-shaped.  
   
   
       4 . A ball pivot in accordance with  claim 1 , wherein said recess is cylindrical.  
   
   
       5 . A ball pivot in accordance with  claim 1 , wherein said magnet is arranged in a ring made of a nonmagnetic material.  
   
   
       6 . A ball pivot in accordance with  claim 5 , wherein said ring is bonded in said recess together with said magnet.  
   
   
       7 . A ball pivot in accordance with  claim 1 , wherein said magnet is embedded in plastic.  
   
   
       8 . A ball pivot in accordance with  claim 7 , wherein the plastic is injected onto said magnet by injection molding.  
   
   
       9 . A ball pivot in accordance with  claim 7 , wherein a body formed by said magnet and said plastic is pressed into said recess.  
   
   
       10 . A ball pivot in accordance with  claim 9 , wherein said body formed by said magnet and said plastic is bonded in said recess.  
   
   
       11 . A ball pivot in accordance with  claim 1 , wherein said magnet is inserted into a stamped and bent part made of a nonmagnetic material.  
   
   
       12 . A ball pivot in accordance with  claim 11 , wherein said stamped and bent part consists of spring bronze.  
   
   
       13 . A ball pivot in accordance with  claim 11 , wherein said stamped and bent part is pressed together with said magnet into said recess.  
   
   
       14 . A ball pivot in accordance with  claim 13 , wherein said stamped and bent part is elastically supported against said inner wall of said recess.  
   
   
       15 . A ball pivot in accordance with  claim 11 , wherein said magnet is pressed into said stamped and bent part.  
   
   
       16 . A ball pivot in accordance with  claim 11 , wherein said stamped and bent part has a ring-shaped design and has two concentric legs and a web connecting these to one another.  
   
   
       17 . A ball pivot in accordance with  claim 16 , wherein said inner leg is embedded in a plastic sleeve.  
   
   
       18 . A ball pivot in accordance with  claim 17 , wherein said magnet is arranged in said plastic sleeve.  
   
   
       19 . A ball pivot in accordance with  claim 1 , wherein said ball pivot consists of a ferromagnetic material, especially a ferromagnetic steel, at least in the area of said recess.  
   
   
       20 . A ball pivot in accordance with  claim 19 , wherein the ball pivot consists entirely of a ferromagnetic material.  
   
   
       21 . A ball and socket joint for a motor vehicle, the ball and socket joint comprising: 
 a ball and socket joint housing;    a ball pivot, which is mounted rotatably and pivotably in said housing and has a pivot and a joint ball connected thereto, said ball pivot having a recess; and    a magnet arranged in said recess, wherein an intermediate space, which is filled with a nonmagnetic material for fixing said magnet, is formed between a jacket surface of said magnet and an inner wall of said recess.
