A wheel of a driven track of a track-type vehicle has a plurality of teeth connected to a hub. A plurality of annular springs is positioned in the openings of the teeth and actuated in response to associated plungers on the springs contacting a portion of the track. The springs controllably resist the impact forces of the track that are directed onto the wheel.
