Title
(EN) RECONFIGURABLE WHEEL-TRACK ASSEMBLY WITH BOWTIE CONFIGURATION
(FR) ENSEMBLE ROUE CHENILLE RECONFIGURABLE À CONFIGURATION EN NOEUD PAPILLON
Abstract
(EN)
The Reconfigurable Wheel-Track (RWT) device is a novel mechanism that allows a wheel to transform into a track, and vice versa. The wheel mode allows a vehicle to travel quickly over smooth and semi-rough terrain, then, on-the-fly, transform rapidly into a powered track mode for crossing extreme terrain. The reconfigurable wheeltrack device comprises several main components: an outer tire/tread, a drive mechanism for driving the tread when in track mode and a reconfiguration mechanism that facilitates the transformation from wheel mode to track mode and vice versa. The reconfigurable wheel-track includes sensing, actuation, and controls to facilitate efficient and effective transitions, and securely maintain each wheel and track shape.
(FR)
L'invention concerne un dispositif roue-chenille reconfigurable, un nouveau mécanisme qui permet à une roue de se transformer en chenille, et inversement. Le mode roue permet à un véhicule de se déplacer rapidement sur un terrain non accidenté ou semi-accidenté, puis le véhicule peut passer immédiatement en mode chenille motorisée pour traverser un terrain extrême. La roue-chenille reconfigurable est constituée de plusieurs composants principaux : un pneu/bande de roulement externe, un mécanisme d'entraînement pour entraîner la bande de roulement en mode chenille et un mécanisme de reconfiguration qui facilite le passage du mode roue au mode chenille et inversement. La roue-chenille reconfigurable comprend des moyens de détection, d'actionnement et de commande pour faciliter des transitions optimales et efficaces et préserver de manière sûre la forme de roue et la forme de chenille.
