A wheel includes a supporting frame, with a central portion having a center around which the wheel can turn, and a plurality of radial portions extending from the central portion angularly displaced with each other. A housing seat is delimited between two adjacent radial portions. A movable element is radially displaceable between a first working position located at a maximum distance with respect to the center, and a second working position located at a minimum distance with respect to the center of the central portion. The radial portions and the movable element have respective distal sections, with respect to the center, curved with a curvature radius corresponding to the curvature radius of the wheel and being flush with each other. A locking element is displaceable between one locking position, wherein it abuts on the movable element and prevents the radial displacement thereof, and one unlocking position, wherein it allows the radial displacement of the movable element toward the second working position. A returning element of the movable element between the supporting frame and the movable element is configured to bring the movable element back into the first working position. A band made of an elastically deformable material surrounds the distal sections of the plurality of radial portions and the movable element, at the circular perimeter of the wheel.

The anti slip device for automobile wheels with wheel discs arranged at inner side plain of the wheel, load-bearing part of which is attachable to the wheel from the outside. The extensible body is placed slidingly in the direction parallel to the wheel axis on the load-bearing part. There are arms fulcrumed on the extensible body around axes parallel to the wheel axis. The arms are fitted, at their ends, with surfaces of engagement, which bear against the tire peripheral surface in the working position. The extensible body is placed on the load-bearing part in the guidance, which comprises at least two pipes, with one outer pipe placed slidingly on each of the pipes and attached to the extensible body. There are tensile springs arranged in the pipes, and these springs are attached by one end to the load bearing part, and by the other end to the extensible body.

The Reconfigurable Wheel-Track (RWT) is a novel mechanism that allows a wheel to transform into a track, and vice-versa. The wheel permits a vehicle to travel quickly over smooth and semi-rough terrain, then, on-the-fly, transform rapidly into a powered track for crossing extreme terrain. The reconfigurable wheel-track consists of several main components: an outer tire/tread, drive mechanisms for the wheel and track, support mechanisms for the outer tread when in either wheel mode or track mode, and a reconfiguration mechanism that facilitates the transformation from a wheel to a track and vice-versa. The reconfigurable wheel-track includes sensing, actuation, and controls to facilitate efficient and effective transition from wheel to track and vice-versa, and securely maintain each shape.
