<p>The invention provides a retractable undercarriage for aircraft, comprising for each landing gear assembly, a leg articulated on the fuselage of the aircraft about a retraction axis which is inclined with respect to the longitudinal plane of symmetry of the aircraft and being in the form of a sleeve in which is journaled a movable assembly carrying at least one wheel, an operating and bracing jacket, in which undercarriage the rod and body of the jack are articulated on the fuselage of the aircraft and on the movable assembly by means of universal joints, and in which there is articulated on the body of the jack a first end of a connecting rod assembly for the transmission of movement, the other end thereof being articulated on the leg so that upon operation of the landing gear under control of the jack, the relative movement of the leg in relation to the jack causes rotation, controlled by the connecting rod assembly, of the jack body which in turn causes rotation of the movable assembly journaled in the sleeve to impart to the wheel or wheels a positioning movement complementary to the movement resulting from operation about the axis of retraction.</p> |
