WHEELED PROPELLER, AUTOMATICALLY CONVERTED TO CATERPILLAR Russian patent published in 2024 - IPC B60B19/00 B60B1/02 B60B15/00 

FIELD: machine building.

SUBSTANCE: wheel consists of tire 1, composite wheel rim 2, flexible spokes 3 and hub 4. Tightened flexible spokes 3 tighten rim 2 and hub 4 together. Tire 1 rests on composite rim 2, which is a set of segments 6 enclosed between rubber limiters. One end of each of flexible spokes 3 is fixed on one of segments 6 of composite rim 2, its middle makes one or two complete revolutions around the separate rotary roller 5, and its second end is fixed on another segment 6 of composite rim 2, which is distant from the first one at angle of 90° along the wheel circumference. Number of flexible spokes 3 is equal to number of segments 6 of composite rim 2 and is calculated depending on type and weight of vehicle. Flexible spoke 3 is a cord made of a bundle of synthetic fibers and enclosed in a tubular plastic sheath for protection from the environment. Flexible spokes 3 are made of high-strength liquid crystal materials. Ends of flexible spoke 3 are securely fixed on segments 6 of composite wheel rim 2 by known fastening methods. Segments 6 of composite rim 2 are made of metal or composite materials.

EFFECT: combination of advantages of high speed of wheeled with cross-country capacity of caterpillar propulsors.
