Problems solved by technology

Although this invention can provide a suspension mechanism with good vehicle body stability and certain ability to adapt to terrain and overcome obstacles, due to the passive suspension structure, the ability to overcome obstacles is limited, and the driving system does not have the functions of folding and unfolding. According to the report of the Spirit Mars rover launched by the United States in 2004, the mobile vehicle for alien exploration should choose an active suspension mechanism with the function of folding and unfolding

Abstract

A 6-wheel symmetrical active suspension structure for the moon exploration car is composed of car body, car body balancing mechanism in the car body, and two suspension sets pivoted to both sides of said car body and to said balancing mechanism. Its 6 wheels are individually driven and can be drawn in car body. Its front 2 wheels and back two wheels can be individual steered. It can move up or down the slope and leap over obstacle or ditch.

Description

technical field [0001] The invention relates to a mechanism in the technical field of machinery, in particular to a six-wheel symmetrical active suspension mechanism for a lunar exploration rover. Background technique [0002] Most of the existing mobile vehicles involved in alien exploration (moon, Mars, etc.) adopt a multi-wheel parallel symmetrical driven suspension mechanism. The lunar rover passes through the launch, transfer orbit, lunar orbit, orbiting the moon, and landing on the moon through the lander. At present, the alien rover is developing in the direction of small size, light weight and compact structure. The Nano Mars rover weighs only 11.5 kilograms. The terrain of the lunar surface is complex, and the lunar rover requires strong ability of flexible obstacle avoidance, obstacle crossing, and self-positioning reset. The obstacle crossing ability requires the lunar rover's exercise system to have strong functions such as climbing, crossing trenches, and anti-...
