Abstract
An aircraft landing gear bogie beam including first and second ends and a mounting bearing for connection to an aircraft landing gear main strut between the ends. Each end has a respective axle, and each axle defines a wheel mounting portion on each side of the bogie beam. The bogie beam is arranged to enable the first and second axles to each pivot relative to the bearing about a respective longitudinal axis of the bogie beam by an amount that is sufficient to place a wheel rim of a wheel assembly in contact with the ground in the event of a tyre of the wheel assembly deflating.
Claims13
An aircraft landing gear assembly comprising:
- an elongate bogie beam including a bearing via which the bogie beam is arranged to be movably mounted to an aircraft landing gear main strut, first and second end regions, a first longitudinal axis extending between the bearing and the first end region and a second longitudinal axis extending between the bearing and the second end region;
- a first axle mounted at a first end region of the bogie beam, the first axle defining a first wheel mounting portion on a first side of the bogie beam for supporting a first wheel assembly and a second wheel mounting portion on a second side of the bogie beam for supporting a second wheel assembly;
- a second axle mounted at a second end region of the bogie beam, with the bearing between the first and second end regions, the second axle defining a third wheel mounting portion on the first side of the bogie beam for supporting a third wheel assembly and a fourth wheel mounting portion on the second side of the bogie beam for supporting a fourth wheel assembly,
- wherein the bogie beam is arranged to enable the first and second axles to each pivot relative to the bearing about the respective longitudinal axis of the bogie beam by an amount which is sufficient to place a wheel rim of a wheel assembly in contact with the ground in the event of a tyre of the wheel assembly deflating.
An aircraft landing gear assembly comprising:
- a first elongate bogie beam including a first bearing via which the first bogie beam is arranged to be pivotally mounted to an aircraft landing gear main strut and defining a first bogie pivot axis;
- a second elongate bogie beam including a second bearing, defining a second bogie pivot axis, via which the second bogie beam is arranged to be pivotally mounted to the aircraft landing gear main strut in a side by side adjacent relationship with the first bogie pivot axis being coaxial with respect to the second bogie pivot axis;
- a first axle mounted at a first end region of the first bogie beam, the first axle defining a first wheel mounting portion on a first side of the first bogie beam for supporting a first wheel assembly;
- a second axle mounted at a second end region of the first bogie beam, the second axle defining a second wheel mounting portion on the first side of the first bogie beam for supporting a second wheel assembly;
- a third axle mounted at a first end region of the second bogie beam, the third axle defining a third wheel mounting portion on a second side of the second bogie beam for supporting a first wheel assembly, the second side facing away from the first bogie beam;
- and
- a fourth axle mounted at a second end region of the second bogie beam, the fourth axle defining a fourth wheel mounting portion on the second side of the bogie beam for supporting a fourth wheel assembly,
- such that the first and second bogie beams can independently pivot about the respective bogie pivot axes in order to place a wheel rim of a wheel assembly in contact with the ground in the event of a tyre of the wheel assembly deflating.
