Abstract

The invention discloses a mars rover elastic wheel. The mars rover elastic wheel comprises a hub, arc-shaped elastic spokes, a wheel surface and excessive deformation protection mechanisms, wherein the hub is cylindrical and one end of the hub is connected with an axle; the hub and the wheel surface are connected through the arc-shaped elastic spokes, one end of each arc-shaped elastic spoke is evenly fixed at equal intervals in the peripheral circle of the hub, and the other end of the arc-shaped elastic spoke is fixed at the inner side of the wheel surface; each excessive deformation protection mechanism comprises a support rod and a top plate. The top plate is supported by the support rod and fixed in the peripheral circle of the hub. The top plate is located between the hub and the wheel surface; the mars rover elastic wheel has a simple structure, the wheel surface has a large deformability, the mars rover elastic wheel has strong recovery, and has a strong adaptability to low-gravity and complex road conditions on the surface of Mars.

Description

technical field [0001] The invention relates to a wheel, in particular to an elastic wheel of a Mars rover. Background technique [0002] Mars is basically a desert planet, composed of aeolian landforms and aeolian landforms. Its surface is covered with a layer of loose regolith, that is, Martian soil. The surface of Mars is severely pitted, with various morphological features, including mountains, canyons, pits, and shields. Volcanoes, river beds, plains, etc., ups and downs, great changes. The distribution density of rocks on the surface of Mars is very high, with a coverage rate of about 14-16%. The average gravitational acceleration on the surface of Mars is equivalent to 38% of the gravitational acceleration on the Earth's surface. The thin atmosphere of Mars makes it difficult to keep the heat from the sun's radiation. Therefore, the temperature difference on the surface of Mars is particularly large, with an average surface temperature of -63°C (the Earth's is 14°C)....
