  "textContent": "To improve a trailer coupling for motor vehicles, comprising a support unit arranged in a rear region of the motor vehicle, a ball neck which carries a coupling ball at a first end and which is held at a second end to the support unit, a groove running around a central axis of the coupling ball, in which a driving ring is rotatably guided around the central axis, and a sensor unit arranged in the coupling ball and detecting rotational positions of the driving ring, such that the driving ring is guided as precisely as possible and is designed to be as wear-resistant as possible, it is proposed that the driving ring has a carrier body made of metal and that driving elements are held on the carrier body, which protrude radially to the central axis outwards over a geometric spherical surface defined by the coupling ball surface.",
