<p>Back-Up Means For Flexible Guard of Track-Type Vehicle The compaction of foreign materials in the track assembly of a track-type vehicle tends to subject the track assembly to unduly high tensions. Such compaction can severely curtail the service lives of undercarriage components. Although flexible guards function well during normal operation, when the vehicle engages an immovable object, the track assembly tends to separate-away from said track roller frame. An imposition of an outside force (FH) on the flexible guard could cause it to bind within the track assembly. This invention is directed to a backup plate secured on the track roller frame for preventing inward movement of the flexible guard substantially within the confines of the track assembly during this condition of vehicle operation.</p> |
