ABSTRACT:
A shock absorbing, tracked wheel assembly of an off-road vehicle has a set f spoke-like structures radiating from the assembly's center or spider. The spoke-like structures include cylinders affixed to the spider and pistons axially translatable in the cylinders. The pistons are biased radially outward by coil springs in the cylinders. The springs' action is dampened by a flow restrictive collar girding the piston and separating fluid in the cylinder into separate chambers. Struts extend from the pistons and the struts have track engagement shoes on their outer ends. The shoes have a generally arcuate sector that engages a track or band in tractive contact with the ground. Rotating the struts about their longitudinal axis will vary the distance between the cylinder and the track shoe so that tension on the track can be adjusted. Sufficient strut rotation allows the track to be removed from the assembly for purposes of track repair or replacement.
