M Alan Kopsco: Cog-augmented wheel for obstacle negotiation. Grumman Aerospace Corporation, Pollock Vande Sande & Priddy, April 24, 1990: US04919489 (123 worldwide citation)

A vehicle for overcoming obstacles includes a wheel having an elastomeric flexible annulus upon which the wheel normally rides. Parallel spaced sprockets receive the annulus and include individual cogs which extend less radially outwardly than the annulus. When an obstacle is encountered, the flexib ...
