Abstract
A track vehicle includes: a frame; a rotatable driving wheel carried by the frame; a track engaged with the driving wheel; an idler wheel engaged with the track; a tensioner coupled to the idler wheel to force the idler wheel into engagement with the track; a recoiler coupled to the tensioner; and a fluid damper attached to the frame and coupled to the tensioner and the recoiler. The fluid damper includes: a fluid chamber having two ports; a piston coupled to at least one of the tensioner and the recoiler within the fluid chamber; and a restriction circuit fluidly connected to the ports and configured to form a closed fluid circuit. The restriction circuit permits a substantially unrestricted fluid flow through the closed fluid circuit when the piston moves in one direction and a restricted fluid flow through the closed fluid circuit when the piston moves in the opposite direction.
