Title: Biased actuating wheels

Abstract: 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 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 apparatus extends from the root into contact with the biasing hoop assembly and is generaly movable for deflecting the biasing hoops and resisting entry into the root for dampening impact, loads, and noise of elements entering the root.
