The invention relates to an aircraft landing gear equipped with a steering device (7) for orienting the wheels (5), the steering device (7) comprising a body (8) in which is incorporated an electromechanical actuator (41) equipped with an electric motor (42). The landing gear is further equipped with damping means intended to limit the transmission of vibration from the wheel (5) to the rest of the landing gear (1) when the aircraft is on the ground. The body (8) of the steering device (7) is mounted with the ability to rotate with a limited amplitude of rotation. The damping means are mounted between the body (8) of the steering device (7) and the strut assembly (2) of the landing gear to damp the vibration between the body (8) of the steering device (7) and the strut assembly (2).
Aircraft landing gear comprising a strut assembly (2) articulated to the structure of the aircraft, a strut (3) sliding along an axis of sliding X in the strut assembly (2) and a free end of which carries at least one wheel (5), a steering tube (4) mounted with the ability to rotate about the axis (X), and a torque link (6) connecting the steering tube (4) and the strut (3) in terms of rotation, the landing gear (1) additionally being equipped with a steering device (7) for orienting the wheel (5) about the axis X, the steering device (7) comprising a body (8) in which is incorporated an electromechanical actuator (41) equipped with an electric motor (42) intended to drive the rotation of the steering tube (4) and therefore of the strut (3) in order to steer the wheel (5), the landing gear being further equipped with damping means intended to limit the transmission of vibration from the wheel (5) to the rest of the landing gear when the aircraft is on the ground, characterized in that the body (8) of the steering device (7) is mounted with the ability to rotate about the axis (X) with a limited amplitude of rotation, and in that the damping means extend between the body (8) of the steering device (7) and the strut assembly (2) to damp the vibration between the body (8) of the steering device (7) and the strut assembly (2).
