Embodiment Construction

[0040] The invention can be applied in an aircraft landing gear (MLG, "Main Landing Gear" in English) of the type comprising in this non-limiting example two wheels arranged symmetrically around a mid-vertical plane.

[0041] However, it should be noted that the invention is equally applicable to aircraft landing gear comprising only a single wheel.

[0042] figure 1 Shows a front detail view of this type of landing gear.

[0043] For the following descriptions, a frame of reference is determined relative to the landing gear, which includes:

[0044] - the longitudinal axis X parallel to the direction of motion of the wheel,

[0045] - the transverse (latéral) axis Y parallel to the direction of the axle,

[0046] - a vertical axis Z perpendicular to the above-mentioned axes.

[0047] Terms such as "front", "rear", "above", "below" are defined with respect to the aforementioned frame of reference.

[0048] exist figure 1 In it can be seen a landing gear strut 100, a shoc...

Abstract

The device has an interface unit installed between an electric motor / reduction gear and a landing gear wheel. An adjustable stop (308) is adjusted such that a rotation blocking unit (305) e.g. claw, of an intermediate pinion (304) is immediately released when a pendular element (302) comes in contact with the stop. Distance between a rotational axis of the element and a rotational axis (310) of a toothed wheel (309) of the interface unit is defined by radii of the pinion and the toothed wheel. The toothed wheel and the pinion are completely meshed when the element is blocked against the stop.

Description

technical field [0001] The invention is directed to a motorized device for aircraft landing gear wheels comprising a clutchable interface device between the wheel and the power unit. Background technique [0002] Currently, in a conventional manner, an aircraft traveling on the ground in the air terminal area from where the aircraft stops requires the assistance of a tow truck that takes it to the point where the jet engines can help propel the aircraft. This constraint introduces a delay before takeoff, and for obvious economic reasons, the aircraft should be turned around as quickly as possible. [0003] Furthermore, when an aircraft lands, the aircraft moves over the ground by using the thrust of its jet engines, which simultaneously creates a noise impact on the adjacent area, inefficient fuel consumption and premature wear of the brakes. [0004] Conversely, an "autonomous aircraft" is referred to as an aircraft that is capable of taxiing from the landing runway to the...
