Disengageable interface mechanism between a motorization system of an aircraft landing gear assembly and a wheel

A mechanism for motorizing a wheel of an aircraft's landing gear comprising a motor-reducer unit and an interface device installed between the motor-reducer unit and the wheel, wherein the interface device comprises:

• an input gear fitted so as to be directly driven by the motor-reducer unit and joined to a rotating shaft along a lateral axis Y;
• a cog wheel along an axis parallel to lateral axis Y capable of driving the wheel rim of said wheel rotationally, with the cog wheel and the input gear arranged on a same vertical plane XZ and a vertical axis Z outlined by center lines of the input gear and the cog wheel, and a longitudinal axis X laid out perpendicular to the vertical Z axis in the middle plane of the cog wheel and the input gear;
• a pendulum element, joined to the rotating shaft and set in the neutral position, carrying an intermediate gear wheel arranged on the XZ plane alongside the input gear, driven in rotation around a parallel lateral axis Y by the rotation of the input gear wheel,
• wherein the intermediate gear wheel contains a rotation blocking device,
• wherein the angular path of the pendulum element around its rotation axis is limited by an adjustable stop, said adjustable stop being set so that when the pendulum element comes into contact with the adjustable stop, the blocking mechanism of the intermediate gear wheel is just released, whereas the blocking mechanism is engaged when the pendulum element is in the neutral position, the distance between the pendulum element's rotation axis and the rotation axis of the cog wheel is determined by the radius of the intermediate gear wheel and said cog wheel, and by the cog wheel and the intermediate gear wheel being fully engaged when the pendulum element comes to be blocked against the adjustable stop.
