Passive rocking arm diamond-type four-wheel lunar rover moving system

Abstract

The invention discloses a rocking arm rhombus four wheels moon vehicle shift system, including a rotary rhombus frame and a front, a rear ,a left and a right wheels with an independent drive system mounted on the frame, the front and the rear wheels are independently fixed on the frame via a front hanger system and a rear hanger system, and the left and the right wheels are independently fixed on the frame via a left hanger system and a right hanger system. The front hanger system and the rear hanger system all consists of a connection mechanism and a steering mechanism. The invent uses a novel type of four wheels three axial rhombus chassis with the advantages of compact structure, high lightness degree, low energy consumption ,big load capacity, good cross country characteristics, convenient posture adjustment, strong land suitability , smooth vehicle body posture and high reliability.

Description

technical field [0001] The invention mainly relates to the design field of walking devices, in particular to a passive swing arm type variable rhombic four-wheel moving system, which can be applied to the field of unmanned detection and ore collection in harsh environments. Background technique [0002] For the lunar surface environment, the lunar rover needs to adapt to the unique lunar surface driving environment such as unfamiliar landforms, dusty layers, and microgravity, and realize the transfer between the earth and the moon, which has special requirements for the vehicle's lightweight and driving performance. Judging from the current domestic research on the lunar rover, it is believed that the traditional two-axis four-wheel mechanism has the advantages of compact structure, low energy consumption, large load capacity, and convenient attitude adjustment. The obstacle ability is not strong; the six-wheel mechanism has the advantages of three-axis characteristics, stro...

Problems solved by technology

Judging from the current domestic research on the lunar rover, it is believed that the traditional two-axis four-wheel mechanism has the advantages of compact structure, low energy consumption, large load capacity, and convenient attitude adjustment. The obstacle ability is not strong; the six-wheel mechanism has the advantages of three-axis characteristics, strong off-road performance and stability, but the disadvantage is that it is difficult to achieve light weight, and the distribution of gravity on each wheel is uneven, and the efficiency of the motor cannot be exerted.

Considering the special working conditions on the moon, it is generally believed that the six-wheeled lunar rover is the best. Although the traditional four-wheeled vehicle is simpler and more reliable than the six-wheeled vehicle, it is not in the selection range because it does not have good off-road performance. within
