Abstract
A pivot assembly for connecting a ground-contacting wheel assembly to a frame member of a track system assembly has a base defining a first interlocking member, a resilient body structured for being received at least partially within the base and having a second interlocking member connectable to the first interlocking member, and an axle assembly configured for rotatably connecting the ground-contacting wheel assembly to the frame member, the axle assembly including a third interlocking member connectable to the second interlocking member. The resilient body is at least partially wrappable around the peripheral surface of the axle assembly. Upon deformation of the resilient body, the axle assembly is pivotally movable relative to the frame member of the track system assembly about at least one of a longitudinal axis and a vertical axis.
