ABSTRACT:
A wheel (1) with variable diameter comprises two mutually opposed disks (2, 3) that can be displaced with respect to each other in the direction of their axis of rotation (6), wherein plates (9) are guided in a substantially radially displaceable fashion. The plates (9) taper in the peripheral direction as measured from one disk (2 or 3) toward the other disk (3 or 2) and are coupled displaceably with each other along their lateral surfaces (20). At least one sliding member (15) is arranged on each plate (9) and is displaceable along a sliding path (19), on the one hand, in the direction of the axis of rotation (6) of the wheel (1) and, on the other hand, in the peripheral direction against the force of springs (18), this sliding member (15) carrying at least one entrainment member (16) for engagement into a load transmission member (22).
