Abstract

Trailer coupling for a motor vehicle (90), in particular a passenger vehicle (90), for attaching a trailer (71) to the motor vehicle (90), comprising a coupling body carrier (11) attached or attachable to the motor vehicle (90) and a vehicle coupling body (15), in particular spherical, arranged at a free end region of the coupling body carrier (11) for coupling with a drawbar coupling (70) of the trailer (71), wherein, in the coupled state, the drawbar coupling (70) and the coupling body (15) are rotatably mounted relative to each other about at least one axis of rotation, in particular multi-axis, and the drawbar coupling (70) is mounted on a bearing surface (16) of the coupling body (15), wherein a driver (35) is movably mounted on the coupling body (15), which has at least one driving projection (51) projecting in front of the bearing surface (16) of the coupling body (15) and is connected to the drawbar coupling (70). is portable and movable relative to the dome body (15),wherein the driver (35) forms a component of a sensor arrangement (30) for detecting an angular position of the coupling (70) relative to the coupling body support (11), characterized in that the driver (35) has at least one receiving cavity (57) for the at least one driving projection (51), into which the at least one driving projection (51) can be displaced by the coupling (70), so that the coupling (70) is movable past the driving projection (51), and in that a center (55) of the at least one driving projection (51) and a center (65) of the associated receiving cavity (57) are arranged one behind the other or are aligned with each other such that the center (55) of the at least one driving projection (51) can be displaced approximately centrally into the receiving cavity (57).
