<p>The trailer coupling has a pivot bearing unit with which a pivot bearing body (14) is pivotable around a rotation axis between defined positions (A, R). A rotatable blocking drive is provided with a deforming controller, where the controller operates an electric drive motor of the blocking drive for play-free deformation of positive locking elements of a rotation blocking device in a deformation operating mode until achievement of deformation moments. The positive locking elements are provided to stand in a rotation blocking position.</p> |
