Rolling device comprising: a bearing housing (2) for accommodation of a wheel axle (8) carrying a wheel element (6), and a drive motor to rotate the wheel element relative to the wheel axle; axle support members (3, 10) accommodated in the bearing housing, the wheel axle extending between the axle support members, with the end portions of the wheel axle connected to the axle support members in an eccentric position; locking means that are operable between an unlocked position allowing the rotation of the axle support members relative to the bearing housing, and a locking position preventing said rotation, wherein in the unlocked position the motor conducts rotation for displacement of the wheel element by an eccentric movement between an extended position where at least a portion of the wheel element projects outside the bearing housing and a retracted position where the wheel element is located inside the bearing housing.
滚动装置,包括:轴承壳体(2),用于容纳承载轮元件(6)的轮轴(8)以及用于使轮元件相对于轮轴旋转的驱动电机;轴支撑构件(3,10),容纳在所述轴承壳体中,轮轴在轴支撑构件之间延伸,轮轴的端部在偏心位置连接到轴支撑构件;锁定器件,可在允许所述轴支撑构件相对于轴承壳体旋转的解锁位置与防止所述旋转的锁定位置之间操作,其中,在解锁位置中,电机引起轮元件的旋转以用于通过在伸出位置与缩回位置之间的偏心移动来使轮元件移位,在伸出位置中,轮元件的至少一部分伸出到轴承壳体之外,在缩回位置中,轮元件位于轴承壳体内部。
