Abstract
A suspension system supports a chassis relative to a crawler mechanism that includes a continuous track. A link is rotatable about an axis extending transversely through a first portion. The first portion includes a projections extending radially inwardly, and peripheral openings defined by spaces between the projections. An axle member secured to the crawler mechanism includes peripheral shafts extending radially outward from the axis and positioned in an associated peripheral opening. Each resilient member is positioned within an associated peripheral opening and engages an associated peripheral shaft, damping movement of the peripheral shaft relative to the link. The suspension system further includes an auxiliary roller assembly including a yoke and a plurality of auxiliary rollers coupled to the yoke. The yoke is rotatable relative to the crawler frame about a yoke axis. The plurality of auxiliary rollers is aligned along a direction of travel of the continuous track and is configured to engage an inner surface of the track.
