A trailer coupling for a motor vehicle may include a coupling element, which is mounted by a bearing so as to be movable between a usage position, in which for attachment of a trailer the coupling element projects rearwards in front of the rear of the motor vehicle, and a rest position, in which the coupling element is moved closer to the motor vehicle, wherein the bearing has a bearing base which is stationary relative to the motor vehicle and a bearing element which is movably mounted on the bearing base and supports the coupling element, wherein the trailer coupling has an electric drive motor by which the bearing element can be driven relative to the bearing base between the rest position and the usage position, and wherein the drive motor has a stator and an armature that is driven relative to the stator. It is provided that the bearing base and the bearing element form drive components, wherein the stator is arranged on one drive component forming a stator drive component, and the armature is arranged on the other drive component forming an armature drive component.

Trailer coupling

A trailer coupling for a motor vehicle comprises a coupling arm, on the free end region of which a ball neck is formed, on which a coupling ball is arranged. The coupling ball is spherical on the side facing away from the ball neck and has a spherical segment plane on the side facing the ball neck. Between the spherical segment plane and a portion of the ball neck has a smaller outer circumference than the spherical segment plane there is arranged a throat portion having a transition contour extending in a concave manner between the ball neck and the spherical segment. The transition contour transitions with a coupling ball transition region into an external contour of the coupling ball and transitions with a ball neck transition region into an outer surface of the ball neck. The transition contour has a curved configuration having a non-constant radius.
