Claim Text:
1. A flywheel assembly comprising: a metal shaft; a composite flywheel rim; a dome connector coupling the composite flywheel rim to the metal shaft, the dome connector including a helically wound composite band extending from a first port to a second port, the helically wound composite band oriented at a helical angle that is offset from a central axis of the dome connector and a line perpendicular to the center axis of the dome connector, wherein, at a first location, an inner surface of the composite flywheel rim and an outer portion of the dome connector are positioned adjacent each other and coupled together, and wherein, at a second location, the inner surface of the composite flywheel rim and the outer portion of the dome connector are spaced apart to define an annular opening between the inner surface of the composite flywheel rim and the outer portion of the dome connector at an axial end of the dome connector; and at least one connector positioned in the opening defined between the inner surface of the composite flywheel rim and the outer portion of the dome connector at the axial end of the dome connector, the at least one connector having a wedge shape comprising a first axial end positioned adjacent to the first location and a second axial end positioned relatively further away from the first location where the inner surface of the composite flywheel rim and the outer portion of the dome connector are spaced apart to define the annular opening, the second axial end exhibiting a width that is greater than a width of the first axial end.
