ABSTRACT:
A wheel of a driven track of a track-type vehicle has a rim connected to a hub with an annular chamber formed between the rim and the hub. A plurality of annular springs are positioned in the chamber and actuated by plungers in response to contacting a portion of the track. The springs controllably resist the impact forces of the track that are directed onto the wheel.
