Abstract
A towing device, for a towing vehicle, with a coupling shaft attached to the towing vehicle, a ball head mounted on the coupling shaft so that the ball head can rotate about a vertical axis, which can be coupled to a coupling counterpart of a trailer vehicle, and with an angle-measuring device by which rotation of the ball head about the vertical axis, relative to the coupling shaft, can be determined, and a force-measuring device by which force exerted by the ball head on the coupling shaft in the direction of the vertical axis can be determined.
