Patent ID: 8393632

Claim:
A towing device for a towing vehicle, the towing device comprising: a coupling shaft ( 8 ) attached to the towing vehicle ( 2 ), a ball head ( 6 ) mounted on the coupling shaft ( 8 ) so that the ball head ( 6 ) being rotatable about a vertical axis ( 10 ), and the ball head ( 6 ) being couplable to a coupling counterpart ( 5 ) of a trailer vehicle ( 3 ), an angle-measuring device ( 22 , 23 ) by which rotation of the ball head ( 6 ) about the vertical axis ( 10 ), relative to the coupling shaft ( 8 ), being determinable, a force-measuring device ( 20 , 22 , 23 ) by which a force (F) exerted by the ball head ( 6 ) on the coupling shaft ( 8 ) in a direction of the vertical axis ( 10 ) is determinable, and the angle-measuring device ( 22 , 23 ) and the force-measuring device ( 20 , 22 , 23 ) both being integrated into the coupling shaft ( 8 ).
