Abstract
A device for steering the wheels fitted to the bottom end of the leg (1) of the nose landing gear of an aircraft, the wheels being steered about the axis of the leg, the leg (1) comprising a strut (2) hinged to the structure of the aircraft, a tube (4) mounted to rotate inside the strut (2) and projecting outside the strut, a rod (5) slidably mounted inside the tube (4) and carrying the wheels at its free end, and a scissor linkage (6) for constraining the tube (4) and the rod (5) to rotate together. At least one actuator (8a, 8b) is situated in a plane substantially perpendicular to the axis of the leg (1), the end of the actuator rod (16a, 16b) being hinged to a side lug (17a, 17b) for rotating the tube (1), and the actuator cylinder being hinged to two parallel plates (7, 10) extending perpendicularly to the axis of the leg ( 1), with one (7) of the plates being fixed to the strut (2) and with the other plate (10) being rotatably mounted about the tube (4) and being prevented from rotating relative to the strut (2) by means of a dog (14) fixed to the strut.
