Wing for an aircraft and high lift assembly

A high lift assembly for a main wing, the high lift assembly comprising:

• a high lift body, and
• a connection assembly configured for movably connecting the high lift body to the main wing, such that the high lift body is movable between a retracted position and at least one extended position,
• wherein the connection assembly comprises an elongate track that extends 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 of the track, or the intermediate portion of the track, or both are mounted to the high lift body,
• wherein the elongate track is configured to be mounted to the main wing by a roller bearing such that the track is movable along the track longitudinal axis;
• wherein the roller bearing comprises a plurality of bearing units, each of the bearing units being configured to be mounted to the main wing and having a bearing surface configurable to engage an engagement surface provided on the elongate track,
• wherein the plurality of bearing units comprises a first end roller unit, an intermediate roller unit, and a second end bearing unit,
• wherein the plurality of bearing units are positioned such that, relative to the track longitudinal axis, the intermediate roller unit is positioned between the first end roller unit and the second end bearing unit;
• and
• wherein the elongate track and the roller bearing are configured such that in the retracted position main loads are transferred between the elongate track and the roller bearing via the first end roller unit and the second end bearing unit and, in the at least one extended position main loads are transferred between the elongate track and the roller bearing via the first end roller unit and the intermediate roller unit,
• wherein in the retracted position, the intermediate roller units are configured to disengage with the engagement surfaces such that a clearance gap exists between the intermediate roller units and the engagement surfaces, and the first end roller units and the second end bearing units are configured to engage the engagement surfaces, and
• wherein in an extended position, the second end bearing units are configured to disengage with the engagement surfaces and the intermediate roller units and the first end roller units are configured to engage with the engagement surfaces.
