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

The disclosure relates to a trailer coupling for a motor vehicle, comprising a carrier assembly having a transverse carrier for arranging on the rear of a motor vehicle and a retainer retained on the transverse carrier for retaining a coupling element of the trailer coupling, wherein the coupling element is provided for fastening a trailer, wherein the retainer is connected to the transverse carrier by a tension anchor of a tension anchor assembly wherein the tension anchor penetrates the transverse carrier along the tension anchor load axis of the tension anchor and loads an abutment surface of the retainer, through which abutment surface the tension anchor load axis or an axis parallel thereto passes, against the transverse carrier. Further, the retainer has at least one side support surface, which projects in front of the abutment surface adjacent to the tension anchor and lies against the transverse carrier such that the retainer is supported on the transverse carrier laterally adjacent to the tension carrier with respect to a force acting transversely to the tension anchor load axis of the tension anchor.

Trailer coupling having a tension anchor

A trailer coupling for a motor vehicle is disclosed, which comprises a carrier assembly having a transverse carrier designed as a profiled part and a retainer retained on the transverse carrier for retaining a coupling element, of the trailer coupling, wherein the coupling element is provided for fastening a trailer or a load carrier, wherein the retainer is connected to the transverse carrier by a tension anchor of a tension anchor assembly wherein the tension anchor penetrates the transverse carrier along the tension anchor load axis of the tension anchor and loads an abutment surface of the retainer, through which abutment surface the tension anchor load axis or an axis parallel to the tension anchor load axis passes, against a side wall of the transverse carrier, said side wall having a through-opening for the tension anchor wherein the tension anchor assembly has a support element having a support surface and a support protrusion, which protrudes from the support surface in the direction of the tension anchor load axis and which engages in the through-opening of the side wall, wherein the support surface of the support element is supported on the side wall of the transverse carrier next to the through-opening by at least one force component in the direction of the load axis and the support protrusion is supported in the through-opening by at least one force component transverse to the load axis.
