This device is designed to transmit lateral and vertical forces generated by the engine to the nacelle stub (10), together with the engine torque, and comprises a main attachment structure and an emergency attachment structure (38). The main attachment structure includes two half-fittings (18a, 18b), connecting rods (20a, 20c) connecting the two half-fittings to the engine and attachment devices for the half-fittings on the nacelle stub. The emergency attachment structure transmits forces between one of the two half-fittings and the nacelle stub when the other half-fitting or its devices for attachment to the nacelle stub are defective. For example, it comprises a hinge pin (42) supported by the nacelle stub and passing through a hole (44) formed in the half-fittings with a clearance.
Composé d'une structure de fixation principale et d'une structure de fixation d'urgence (38), le dispositif sert à transmettre les forces latérales et verticales du moteur au moignon du fuseau (10), ainsi que le couple moteur. La structure de fixation principale comporte deux ferrures (18a, 18b), des bielles (20a, 20c) servant au raccordement des ferrures au moteur et des dispositifs de fixation destinés à retenir les ferrures au moignon de la nacelle. La structure de fixation d'urgence transmet la force entre l'une des ferrures et le moignon lorsque l'autre ferrure ou ses dispositifs font défaut. Elle comprend ainsi une broche de charnière (42) que soutient le moignon de la nacelle et qui passe par un trou (44) percé dans les ferrures, auquel on a assuré un jeu.
