Abstract
A coupling lock for a trailer coupling. The coupling lock comprises a receptacle (9) in which a coupling element (6) is inserted, an angle measuring device (13, 19) is connected to the receptacle (9), and the angle measuring device (13, 19) is provided for detecting rotation of the receptacle (9), about a rotational axis (18), relative to the coupling element (6). A magnetically adhering body (24) is elastically connected to the receptacle (9) and magnetically connectable to the coupling element (6) for actuating the angle measuring device (13, 19).
Claims15
A coupling lock, for a trailer coupling, comprising:
- a receptacle (9) in which a coupling element (6) is inserted,
- an angle measuring device (13, 19) being connected to the receptacle (9), and the angle measuring device (13, 19) detecting rotation of the receptacle (9), about a rotational axis (18), relative to the coupling element (6),
- a magnetically adhering body (24) being elastically connected to the receptacle (9) and magnetically connectable to the coupling element (6) for actuating the angle measuring device (13, 19).
A coupling lock (8) in combination with a trailer coupling (4) located between a tractor vehicle (1) and a trailer vehicle (2), the coupling lock (8) comprising:
- a receptacle (9) in which a coupling element (6) is inserted,
- an angle measuring device (13, 19) connected to the receptacle (9), and the angle measuring device (13, 19) detecting rotation of the receptacle (9), about a rotational axis (18), relative to the coupling element (6),
- a magnetically adhering body (24) being elastically connected to the receptacle (9) and magnetically adhering to the coupling element (6) and for actuating the angle measuring device (13, 19) such that a bend angle (α), between a longitudinal axis (11) of the tractor vehicle (1) and a longitudinal axis (12) of the trailer vehicle (2), is determined from rotation detected by the angle measuring device.
