FLEXIBLE GUARDS FOR UNDERCARRIAGE

摘要

A track-type vehicle undercarriage (12) having front and rear wheels (18, 21), a support frame (16), a roller assembly (24) attached to the support frame (16), an endless track (31), and an elastomeric guard (32) having first and second portions (44, 45) and being connected at said first portion (44) to at least one of said roller assembly (24) and said support frame (16), and extending downwardly to a position adjacent a bottom run of the endless track (31), said guard second portion (45) contacting at least one of said support frame (16) and said roller assembly (24) in response to forces on said elastomeric guard (32) in a direction toward said respective support frame (16) and roller assembly (24). This provides a guard (32) decreasing the amount of debris entering the undercarriage (32) of a track-type vehicle (10), this guard (32) being suited for use on a soft-bottom or resilient undercarriage.
