    • A power transmission device includes first and second rings arranged opposite each other, having a common rotation center axis, and rotatable relative to each other; a plurality of planetary balls having rotation center axes parallel to the rotation center axis, and radially arranged between the first and second rings and around the rotation center axis; a transmission control unit configured to change a rotation ratio between the first and second rings by changing the respective contact points of the first and second rings and each of the planetary balls through tilting motion of each of the planetary balls; and a rotation restricting unit disposed between the planetary balls adjacent to each other.
    • 动力传递装置包括彼此相对布置的第一和第二环,具有共同的旋转中心轴线并且可相对于彼此旋转; 多个行星球,其旋转中心轴与旋转中心轴平行,并且径向配置在第一和第二环之间并且围绕旋转中心轴线; 变速器控制单元,其被配置为通过通过每个所述行星球的倾斜运动来改变所述第一和第二环和每个所述行星球的各个接触点来改变所述第一和第二环之间的旋转比; 以及设置在彼此相邻的行星球之间的旋转限制单元。
