Problems solved by technology

In addition, when the gravity of the lunar surface is 1 / 6g, the high-speed rotation of the wheels is likely to generate a lot of dust during driving, which will affect the load of the detection instrument and even the driver's line of sight.

Embodiment Construction

[0037] The present invention will be further described in detail in conjunction with the accompanying drawings and the specific embodiment of the manned lunar vehicle wheel.

[0038] Such as figure 1 , figure 2 with image 3As shown, the concave elastic screen wheel of the present invention includes a protective plate 7, a protective plate support 8, an anti-skid pawl 5, a wire mesh 6, a spring leaf 9, a support ring 12, a bow frame 10, a crescent-shaped wheel spoke 3, an elastic foam Filler plate 4, hub 2, support ring 12 and drive motor 1. The driving motor 1 is installed in the center of the hub 2 and is the driving part of the wheel. The wheel hub 2, the crescent-shaped spokes 3, the support ring 12, the spring leaf 9 and the bow frame 10 play a main supporting role. The hub 2 is rigidly connected to the support ring 12 . The fixed end 13 of the leaf spring 9 is fixed on the support ring, and the free end 11 of the spring leaf is attached to the surface of the suppor...

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,...
