    • A flywheel comprising a rim (1) which is a substantially circular ring mounted on a central portion (2) which central portion comprises at least one substantially circular dished member which has a specific modulus which is less than the specific modulus of the rim, the dished member being curved such that increasing rotational speed tends to elastically deform the dished member, straightening the curve, thereby increasing the diameter of the dished member. In a preferred embodiment, the central portion (2) comprises at least two co-axial dished members (3,4) which are imperforate apart from a central hole (5), each dished member comprising three integrally formed annular portions, two of the portions (6,8) being curved and being positioned on each side of the third portion which is straight or curved.
    • 一种飞轮,包括边缘(1),所述边缘是安装在中心部分(2)上的基本圆形的环,所述中心部分包​​括至少一个基本圆形的碟形部件,所述基本圆形的碟形部件的比模量小于所述边缘的比模量, 碟形构件弯曲,使得增加的旋转速度趋向于弹性变形碟形构件,矫直曲线,从而增加碟形构件的直径。 在优选实施例中,中心部分(2)包括至少两个不与中心孔(5)隔开的同轴凹槽构件(3,4),每个凹形构件包括三个整体形成的环形部分,其中两个 部分(6,8)是弯曲的并且位于第三部分的直的或弯曲的每一侧上。
