BIASED ACTUATING WHEELS

摘要

BIASED ACTUATING WHEELS Drive or driven wheels of a track-type vehicle have a hub and a plurality of teeth around the outer periphery each of which are spaced one from the other by an intervening root area having an opening. A biasing hoop assembly having a multiplicity of generally concentric biasing hoops encompass the hub and are positioned between the hub and teeth. Actuating means extends from the root area into contact with the biasing hoop assembly and is generally movable for deflecting the biasing hoops and resisting entry into the root area for dampening impact, loads, and noise of elements entering the root area.
