Deformable wheel with non-pneumatic load support and rotating stop disc for lunar and Martian conditions

Abstract

The invention relates to a deformable wheel (2) with a non-pneumatic load-bearing support intended to equip a vehicle for driving in extreme conditions such as those found on the moon and on Mars, comprising a hub (4) carrying at least one thrust disc (20) projecting radially outwards, a tread (6) having an outer surface intended to be in contact with the ground by being able to deform under a load applied from the outside to adapt to the ground surface, and an inner surface that can bear against the thrust disc to limit deformations of the tread in radial directions, and a plurality of radial reinforcements (8) connecting the tread to the hub, the thrust disc being movably mounted in rotation on the hub so as to be rotationally adjusted when the inner surface of the tread bears against the thrust disc.
