DEFORMABLE SUPPORT WHEEL WITH RESILIENT CHAMBER AND TRACK SYSTEM HAVING SAME

Abstract: a deformable support wheel with a resilient chamber for a vehicular track-based system, is presented. the track-based support wheel comprises a central hub aperture portion configured to receive and operatively connect to a corresponding axle; a sidewall portion configured to concentrically surround an outer peripheral surface of the central hub aperture portion, the sidewall portion comprising a pair of radially-extending flanges that are laterally spaced apart from each other; and a deformable tire portion concentrically mounted on the sidewall portion. the inner surface of the flanges and an outer peripheral surface of the sidewall portion define a resilient chamber that provides a spacing between the outer peripheral surface of the sidewall portion and an inner peripheral surface of the tire portion. the support wheel structure minimizes lateral deformations caused by compression/shearing forces experienced during challenging environmental conditions by redirecting the deformations radially inward towards the resilient chamber.
