Abstract

A wing having a main wing and a high lift assembly with a body and a connection. The connection movably connects the body to the main wing, such that the body is movable between a retracted position and at least one extended position. The connection comprises a track extending along a longitudinal axis between a first end and a second end and an intermediate portion between the ends. The first end and/or the intermediate portion is mounted to body, and the second end and/or the intermediate portion is mounted to the main wing by a roller bearing such that the track is movable along the longitudinal axis. The roller bearing has a roller unit mounted to the main wing and engaging a surface provided at the track so that the roller unit can adapt its tilt position with respect to the surface.

First claim

The invention claimed is:

1. A wing for an aircraft, comprising:
a main wing,
a high lift body, and
a connection assembly movably connecting the high lift body to the main wing such that the high lift body is configured to move between a retracted position and at least one extended position,
wherein the connection assembly comprises an elongate track extending along a track longitudinal axis between a first end and a second end and has an intermediate portion between the first and second ends,
wherein the first end, the intermediate portion of the track, or both are mounted to the high lift body,
wherein the second end, the intermediate portion of the track, or both are mounted to the main wing such that the track is configured to move along the track longitudinal axis,
wherein at least one roller comprises at least one roller engaging an engagement surface provided at the track,
wherein the at least one roller is configured to adapt a tilt position with respect to the engagement surface,
wherein the at least one roller unit comprises a first frame and a second frame,
wherein the second frame is rotatably mounted to the first frame and rotatable about a roller rotation axis, and
wherein the second frame is further rotatably mounted to the first frame and rotatable about a frame rotation axis extending perpendicular to the roller rotation axis.

2. The wing according to claim 1 , wherein a first shaft forming the roller rotation axis extends between the first frame and the second frame such that a first relative rotational movement between the first frame and the second frame is achieved about the roller rotation axis, or
wherein a second shaft forming the frame rotation axis extends between the first frame and the second frame such that a second relative rotational movement between the first frame and the second frame is achieved about the frame rotation axis, or
both.

3. The wing according to claim 1 , wherein the first frame, the second frame, or both are formed as a housing around the at least one roller,
wherein the housing has at least one opening, and
wherein the at least one roller extends through the at least one opening, so that a roller surface of the at least one roller engages with the engagement surface of the track in an area of the at least one opening.

4. The wing according to claim 1 , wherein the track has a profile comprising an upper flange portion, a lower flange portion, and at least one web portion connecting the upper flange portion and the lower flange portion,
wherein the at least one roller unit is arranged in a recess between the upper flange portion and the lower flange portion and engages the engagement surface provided at the upper flange portion, at the lower flange portion, or at both.

5. The wing according to claim 1 , wherein the at least one roller unit comprises at least a first roller and a second roller,
wherein the second roller is spaced from the first roller along the track longitudinal axis.

6. The wing according to claim 1 , wherein the track comprises a profile having a first recess formed between an upper flange portion and a lower flange portion at a first side of a web portion, and
a second recess formed between the upper flange portion and lower flange portion at a second side of the web portion opposite the first side of the web portion.

7. The wing according to claim 6 , wherein the at least one roller unit comprises at least a first roller and a second roller,
wherein the first roller is arranged in the first recess and the second roller is arranged in the first recess.

8. The wing according to claim 7 , wherein the first roller and the second roller are spaced apart from one another along the track longitudinal axis.

9. The wing according to claim 1 , wherein the connection assembly is a first connection assembly, wherein the wing comprises a second connection assembly connecting the high lift body to the main wing in a position spaced apart from the first connection assembly in a wing span direction, and wherein the second connection assembly is formed as the first connection assembly.

10. An aircraft comprising the wing according to claim 1 .
