Abstract (en)
[origin: EP1990558A1] The assembly (1) has a primary nut (3) and a secondary nut (5) cooperating with a screw and equipping a trimmable horizontal stabilizer actuator of an aircraft. A mechanical link between the nuts includes a fusible driving unit formed of a connecting rod (7) and a pin (9) for driving the secondary nut by the primary nut. The mechanical link includes an adjustable spacing unit forming a wedge (11) between the nuts, where the wedge has adjustable thickness. The rod is anchored in the primary nut and extends in the secondary nut.
