Patent Abstract

The wheel (20) has a wheel disk with a rolling surface, where a rolling surface has a variable radius (24) relative to an axis, such that the rolling surface has two protrusions (22). The axis is provided for mounting of the wheel for rotation. The protrusions are respectively asymmetric corresponding to the radius of the wheel. The protrusions have a portion with a constant radius. Multiple wheel disks are provided that are arranged around the axis and are rotatable relative to each other.
