a planetary vehicle

Abstract

The invention discloses a planetary rover. The planetary rover comprises a frame and wheels located beneath the left side and the right side of the front end and the left side and the right side of the rear end of the frame. The planetary rover is characterized in that the planetary rover further comprises a suspension system, and the suspension system comprises two rocker arms which are arranged on the vertical planes of the front end and the rear end of the frame in the width direction respectively; each rocker arm comprises two splayed oscillating bars which are symmetrical left and right and a transverse connecting rod which is horizontally and fixedly connected to the upper ends of the oscillating bars, the middle of each transverse connecting rod is rotatably mounted on the frame through a bearing arranged in the front-rear direction of the middle position of the frame, the lower ends of the oscillating bars are provided with the wheels through driving systems, the middle of each oscillating bar is connected with the upper end of a spring damping mechanism in an axial sliding mode, and the lower end of each spring damping mechanism extends in the lower-inner direction and is connected with a hinged support vertically fixed to the frame through a hinge shaft horizontally arranged in the front-rear direction. The planetary rover is good in dumping resistance and drive control performance, high in traveling stability, capable of being better adapted to traveling in planet complex terrains, and the like.

Description

technical field [0001] The invention relates to the field of aerospace equipment; in particular, it relates to a planetary vehicle. Background technique [0002] A planetary vehicle is a vehicle used to walk on the surface of a planet and carry out exploration investigations during interstellar exploration in the field of aerospace. In recent years, with the needs of the rapid development of the aerospace industry, the exploration and research on planets has continued. From the lunar exploration project to the exploration of Mars, people are more and more interested in the exploration of space planets. The surface of the planet is rugged, with rocks, craters, and slopes. At the same time, the planetary vehicle needs to be loaded with important exploration instruments. In this case, it must be ensured that the planetary vehicle has good shock absorption and load-bearing capacity and cannot overturn.

AI Technical Summary

Problems solved by technology

[0003] The currently designed planetary vehicles are designed with reference to ordinary vehicles, and it is difficult to meet the requirements of anti-overturning ability for complex terrain walking on the planet. When driving on rough roads, the wheels of planetary vehicles may not be able to touch the ground at the same time, which will affect the carrying capacity. It is easy to cause rollover due to the deviation of the center of gravity of the vehicle when driving

At the same time, its wheel drive steering system is also difficult to adapt to the driving needs of complex terrain, and it is difficult to better ensure the stability of driving
