Abstract

The invention discloses a walking system of planet vehicle with planet gear, comprising vehicle body, two planet gears and pre and post assistant wheels. Said planet wheels are set at left and right sides of vehicle body respectively and they are connected by synchronic device in the middle. Said pre and post assistant wheels are set at the front and the back of vehicle body and they are connected by linkage device set at the center of vehicle body in the middle. The invention not only realizes the improvement of passing capacity of vehicle in soft land and obstacle but also makes vehicle possess the capacity that vehicle can be folded and unfolded; the distance between vehicle body and the land can be adjusted; the whole vehicle can be oblique and there is pre-selecting driving project.

Description

technical field

[0001] The invention relates to an extraterrestrial vehicle for spaceflight, in particular to a traveling system of a planetary wheel type planetary vehicle. Background technique

[0002] The current extraterrestrial exploration vehicles mostly use the multi-wheel side-by-side rocker suspension mechanism as the main configuration of the walking system. For example, the "lunar vehicle 1" launched by the Soviet Union adopted a parallel 8-wheel structure with unilateral double rocker suspension. The Mars rovers "Sojourney" and "Opportunity" launched by the United States adopted a 3-wheel rocker suspension structure developed from a 2-wheel rocker suspension on one side. But this kind of suspension is far from enough to pass through the complex environment unknown to the alien body. At the end of April 2005, the US "Opportunity" Mars rover was immobilized due to driving on a 30-centimeter-high sand pile, and was trapped for a month.
