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 field of mechanical technology, in particular to a six-wheel symmetrical active suspension mechanism of a lunar exploration vehicle. Background technique [0002] Most of the existing mobile vehicles related to extraterrestrial exploration (moon, Mars, etc.) adopt multi-wheel parallel symmetrical driven suspension mechanisms. The lunar exploration vehicle is launched by the lander, transferred to the orbit, flew to the moon orbit, flew around the moon, and landed on the moon. At present, the alien exploration vehicle is developing in the direction of small size, light weight, and compact structure, such as the Sodger of the United States. The Na Mars rover weighs only 11.5 kilograms. The terrain on the surface of the moon is complex, and the lunar exploration vehicle is required to have strong flexible obstacle avoidance, obstacle surmounting, and self-positioning reset capabilities. Among them, the obstacle...
