Abstract: The present invention relates to a hub assembly of a rotor for holding at least one wing, wherein the at least one wing is connected/mounted to the hub assembly in at least two suspension points. The hub assembly may be applied to any kind of either energy extracting devices such as wind turbines or the like or lift producing devices such as helicopter rotors or propellers. The invention is suited for rotors in general and is able to enable coning movement of wings connected/mounted to the hub assembly, enable teetering movement of the rotor and enable alteration of the pitch angle of the wings connected/mounted to the hub assembly. The hub assembly according to the present invention provides a hub where the pitching of the wings can occur synchronously/simultaneously due to an interconnection of the wings attached/mounted to the hub assembly and where coning of the wings may be applied at the same time with pitching of the wings and teetering of the rotor.
