Four-wheeled manned lunar rover adjustable suspension

Abstract

The invention relates to four-wheeled manned lunar rover adjustable suspension. The four-wheeled manned lunar rover adjustable suspension comprises suspension left rocker arms, suspension right rockerarms, wheel mechanisms, a lunar rover chassis, left springs, right springs and telescopic rods; the suspension left rocker arms and the suspension right rocker arms are distributed at the front end and the tail part of the lunar rover chassis; the suspension left rocker arms are hinged to the lunar rover chassis through first hinged shafts; the suspension right rocker arms are hinged to the lunarrover chassis through second hinged shafts; and the adjacent suspension left rocker arms and suspension right rocker arms are connected through the left springs, the telescopic rods and the right springs. The suspension left rocker arms, the suspension right rocker arms and the wheel mechanisms constitute a splayed-shaped suspension mechanism for walking; the left springs and the right springs constitute a spring mechanism for shock absorption; and the telescopic rods form a telescopic rod mechanism for adjusting the wheel distance. According to the four-wheeled manned lunar rover adjustablesuspension, the springs are used for the shock absorption of running of a lunar rover, the rover spacing of the lunar rovers is adjusted by using the stretching and retracting of the telescopic rods,the height of the lunar rover is reduced, the running stability of the lunar rover is improved, and the wheel distance is increased to enable the lunar rover to pass through a plurality of big obstacles.

Description

technical field [0001] The invention designs a manned lunar vehicle suspension, and in particular relates to an adjustable wheel spacing suspension. Background technique [0002] The goal of the lunar exploration project in the 21st century is to establish a lunar base and begin to develop and utilize the resources of the moon. Manned landing on the moon and exploration are the main direction of my country's deep space exploration. The suspension design of the lunar rover is an important part of the manned lunar rover. The design of the suspension directly affects the ability of the lunar rover to walk and overcome obstacles, and adapt to various complex terrains. Good shock absorption is important due to the unevenness of the lunar surface. Since there will be pits on the surface of the moon, crossing obstacles is also an essential function. The traditional moon and car walking system does not have these perfect functions, so a suspension design with multiple functions to...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defect that the existing lunar vehicles cannot adapt to various walking conditions, the present invention provides an adjustable suspension for four-wheeled lunar vehicles. Adjust the relative position of the wheels and the ground, and then control the wheels to drive on rough ground
