Abstract
In a measuring device for measuring an articulation angle between a tractor vehicle which has a longitudinal axis, and a trailer which has a longitudinal axis, with a trailer coupling which trailer coupling includes a coupling ball, a ball receptacle which serves to receive the coupling ball, and at least one magnetic sensor it is proposed that the coupling ball have a ball opening, that a magnet be mounted in the ball opening, and that the ball receptacle have a recess, and that the at least one magnetic sensor be mounted in the recess, wherein changes in a magnetic field generated by the magnet are sensed by the magnetic sensor.
Claims14
A measuring device for measuring an articulation angle between a tractor vehicle having a first longitudinal axis and a trailer having a second longitudinal axis, the tractor vehicle and the trailer being coupled by a trailer coupling having a coupling ball and a ball receptacle adapted to receive the coupling ball, the measuring device comprising:
- a magnet mounted in a ball opening of the coupling ball;
- and
- at least one magnetic sensor mounted in a recess of the ball receptacle and adapted to detect changes in a magnetic field produced by the magnet;
- wherein a center of the magnet is positioned approximately at a center point of the coupling ball, such that the articulation angle is measured independently of tilting movements and rotations which occur about at least one of the first longitudinal axis and the second longitudinal axis.
