Concave elastic screen wheel

Abstract

The invention discloses a concave elastic screen wheel which comprises a hub and a supporting ring arranged on the hub. An annular metal wire mesh is arranged at the outer periphery of the supporting ring, an elastic element for supporting the metal wire mesh is positioned between the supporting ring and the metal wire mesh, an antiskid pawl is positioned at the outer periphery of the metal wire mesh, the metal wire mesh and the antiskid pawl are fixedly connected to form an arch concave elastic screen serving as a tire face, and the tire face is an arch concave face with the concave middle and the two convex sides. The concave elastic screen wheel can carry people to walk in soft, dusty, dry and low-gravity environments, can meet the requirements of high roll stability, high adhesion force and good shock absorption performance, can effectively prevent settlement and can effectively restrain raised dust.

Description

technical field

[0001] The invention relates to the field of deep space exploration such as manned moon landing and Mars exploration, in particular to a concave elastic screen wheel, which can be used for operation and carrying equipment in special environments such as manned lunar vehicles. Background technique

[0002] The existing planetary surface inspection probes in the field of deep space exploration are mainly divided into two types: unmanned and manned. Due to the small weight and extremely low speed of unmanned patrolling probes, such as the American Spirit, the Opportunity Mars rover, and the former Soviet Lunokhod-1 / 2, etc., the wheels used generally have small wheel diameters, poor climbing performance, and low load capacity. The disadvantage of not being strong. At present, the American Apollo LRV manned lunar rover wheel that has achieved manned landing on the moon is a metal elastic screen wheel. The shape of the wheel is similar to that of a ground vehicle,...
