Abstract
A wheelchair suspension includes a frame, a pivoting assembly, at least one front caster, and at least one rear caster. The pivoting assembly has a first link pivotally coupled to the frame member, a second link pivotally coupled to the frame member, a drive assembly fixedly connected to a first end of the first link, and a third link pivotally connected to the first link and pivotally connected to the second link. The drive assembly causes downward pivotal movement of the first end of the first link and upward pivotal movement of a second end of the first link. The upward pivotal movement of the second end of the first link causes the second link and the caster assembly to undergo upward movement.
