Tumbling ball joint for pivotable trailer coupling, has joint ball with front side formed as toothed wheel plate, which meshes with bevel gears that are rotatably supported at housing and rotatable by drive
The joint has a ball pivot (4) comprising a pin (3) and a joint ball (2). The ball pivot extends through a pin opening (8) of a housing (6) so that the pin projects from the housing. The ball pivot and the housing move relative to each other by a drive (19). A front side, which is turned towards the pin, of the joint ball extends diagonally towards longitudinal axis (11) of the ball pivot and formed as a toothed wheel plate (10). The plate meshes with bevel gears (12, 13), which are rotatably supported at the housing and rotatable by the drive.
