Aircraft landing gear assembly
First Claim
Patent Images
1. An aircraft landing gear assembly comprising:
- a first part and a second part, the first and second parts being movably mounted with respect to one another;
a structural member pivotally coupled to the first part via a first joint, the structural member having a load reacting condition in which it inhibits relative movement between the first and second parts by reacting to a compressive load applied to it by the parts,the first joint including a first bearing surface associated with the first part and a second bearing surface associated with the structural member, the first joint being arranged such that the first bearing surface mechanically couples with the second bearing surface during said compressive loading so as to define a load path between the first and second bearing surfaces by each bearing surface engaging a respective bearing counter-face; and
one or more springs,wherein the first and second bearing surfaces each define male and/or female engagement formations arranged to engage with the respective first and second counter-faces to inhibit pivotal movement of the structural member relative to the first part when the first and second bearing surfaces are engaged in an interlocking condition with the respective first and second counter-faces, the one or more springs being arranged to urge the first and second bearing surfaces to assume a spaced condition in which they are relatively spaced from the respective first and second counter-faces so as to permit said pivotal movement of the structural member relative to the first part.

Abstract
An aircraft landing gear assembly includes a structural member coupled to another part by a joint including engagement formations or a relatively high friction coating arranged such that the joint inhibits pivotal movement of the structural member when the structural member is compressively loaded in an axial manner.

5. An aircraft landing gear assembly comprising:
-
a first part and a second part, the first and second parts being movably mounted with respect to one another; and a structural member pivotally coupled to the first part via a first joint, the structural member having a load reacting condition in which it inhibits relative movement between the first and second parts by reacting to a compressive load applied to it by the parts, the first joint including a first bearing surface associated with the first part and a second bearing surface associated with the structural member, the joint being arranged such that the first bearing surface mechanically couples with the second bearing surface during said compressive loading so as to define a load path between the first and second bearing surfaces by each bearing surface engaging a respective bearing counter-face, wherein at least one of the first bearing surface and the first counter-face and at least one of the second bearing surface and the second counter-face is defined by a layer of first material having a coefficient of friction which is relatively high in comparison to that of a second material from which at least one of the structural member, the first part and the second part is formed. - View Dependent Claims (6, 7, 8, 9, 10, 16, 17, 18, 19, 20)
