Initiatively rocking arm variable diamond-type four-wheel lunar rover moving system

Abstract

The invention discloses an active swing arm type variable diamond four-wheel lunar rover moving system. The system comprises a diamond like vehicle frame, a front wheel, a rear wheel, a left wheel and a right wheel with an independent driving system positioned on the vehicle frame. The front wheel and the rear wheel are fixedly positioned on the vehicle frame via a front suspension system and a rear suspension system. The left wheel and the right wheel are fixedly positioned on the vehicle frame via the left suspension system and the right suspension system. The front suspension system and the rear suspension system comprise a swing arm type power mechanism and a steering mechanism. The front wheel and the rear wheel change direction in linkage. The left suspension system and the right suspension system comprise a swing arm type power mechanism. Adopting the structure of the four-wheel three-axis diamond chassis and the active swing arm, the invention initially plays the high-efficient mobility of wheel type driving mode and the crawling ability of foot type moving system, and the invention relates to the active swing arm type variable diamond four-wheel lunar rover moving system with simple and compact structure, low cost, being suitable for operation under various severs environments, wide application, good stability, high reliability and strong flexibility of steering.

Description

technical field [0001] The invention mainly relates to the design field of walking devices, in particular to an active rocker-type variable diamond-shaped four-wheeled lunar rover moving system, which can be applied to the fields of unmanned detection and ore collection in harsh environments. Background technique [0002] At present, domestic lunar exploration vehicles basically adopt a six-wheel driving system arranged in parallel, and the structure is relatively complicated, which directly affects its light weight and reliability. In addition, the suspension mostly adopts a passive grounding method, and its off-road performance and maneuverability are limited to a certain extent. 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 ...

AI Technical Summary

Problems solved by technology

It is generally believed that the six-wheeled lunar rover is the best, and the traditional four-wheeled vehicle, although simpler and lighter than the six-wheeled vehicle, is not in the range of choice because it does not have off-road capabilities.
