Abstract
A landing gear assembly for an aircraft, the landing gear assembly including: an elongate bogie beam; a first axle bearing having an outer part rotatably coupled to an inner part, the outer part being coupled to the bogie beam, the inner part including a mounting aperture; and an elongate axle provided through the mounting aperture of the inner part and coupled thereto, wherein the axle is coupled to the inner part of the first axle bearing in a configuration such that the longitudinal axis of the axle is spaced from the axis of rotation of the inner part, such that rotation of the inner part causes a change in the orientation of the axle relative to the bogie beam.

A landing gear assembly for an aircraft, the landing gear assembly including:
- an elongate bogie beam;
- a first axle bearing having an outer part rotatably coupled to an inner part, the outer part of the first axle bearing being coupled to the bogie beam, the inner part of the first axle bearing including a mounting aperture;
- and
- an elongate wheel axle provided through the mounting aperture of the inner part of the first axle bearing and coupled thereto,
- wherein the axle is coupled to the inner part of the first axle bearing in a configuration such that a longitudinal axis of the axle is parallel with respect to an axis of rotation of the inner part of the first axle bearing when the inner part of the first axle bearing is at a first angular position relative to the outer part of the first axle bearing, and the longitudinal axis of the axle is spaced from the axis of rotation of the inner part, such that rotation of the inner part causes a change in the orientation of the axle relative to the bogie beam.
