  • Self-damping caster wheel
    Patent number: 4989920
    Abstract: A caster wheel which enhances critical shimmy velocity so as to minimize shimmy effects in operation. Two tread surface for contact with a ground surface and a pivot assembly for pivoting the wheel about a first vertical axis displaced from a second vertical axis extending through the center point of the wheel are provided such that the separation between the two tread surfaces strategically relate via a mathematical equation to said displacement in a manner for achieving a desired critical shimmy velocity.
