Patent ID: 7631734

Claim:
An elastomeric brake mechanism, comprising: a rotatable wheel having a first side; a ring having a first side and a circular roller surface, the ring positioned relative to the wheel such that the first side of the ring is disposed towards the first side of the wheel; an elastomeric suspension comprising a plurality of springs disposed around the wheel and coupling the ring to the wheel the elastomeric suspension configured such that a first end of each of the plurality of springs is coupled to the ring and a second end of each of the plurality of springs is coupled to the wheel allowing the ring to move relative to the wheel from a first ring position toward a second ring position; and a roller having a circular outer surface disposed toward the roller surface of the ring, the roller configured to move from a first roller position toward a second roller position, the roller outer surface contacting the ring roller surface in both the first roller position and the second roller position such that the movement of the roller from the first roller position towards the second roller position moves the ring from the first ring position towards the second ring position, wherein the elastomeric suspension is deformed into an eccentric position by the movement of the ring from the first ring position towards the second ring position.
