Landing gear with retractable rocker arm provided with an electric motor and aircraft provided with at least one such landing gear

A retractable landing gear for an aircraft, the landing gear comprising:

• a rocker arm intended to be hinged to a structure of the aircraft and carrying at least one wheel, the wheel(s) being able to move between a deployed position and a retracted position;
• a shock-absorber provided with a stem that slides in a body, the shock-absorber being intended to be hinged to the structure;
• a strut provided with a first connecting link and a second connecting link that are hinged to each other by a first mechanical link, the first connecting link being hinged to the shock-absorber;
• and
• an actuator,
• wherein the actuator is intended to be connected to the structure and connected to the second connecting link in order to rotate the second connecting link in relation to the structure, the landing gear comprising:
• a connecting rod hinged to the shock-absorber by a second mechanical link with a single degree of rotational freedom and to the rocker arm, the connecting rod being out of alignment with the shock-absorber when a force less than a predetermined force is applied to the shock-absorber;
• and
• a locking device comprising an elastic return member and a stop device, the elastic return member being fastened by two ends respectively to the strut and to a hinged assembly comprising the rocker arm, the connecting rod and a third mechanical link between the rocker arm and the connecting rod, the elastic return member applying a pulling force between the strut and the hinged assembly, the stop device being configured to prevent movement of the first and second connecting links in relation to each other about an axis of rotation of the first mechanical link generated by the pulling force when the wheel is in the deployed position.
