ABSTRACT:
An endless track assembly for a track-type vehicle comprises a plurality of track shoes secured to an articulated chain. The links of the chain are pivotally interconnected together by pin and bushing assemblies adapted to engage a drive sprocket of the vehicle. A cushioning lug is secured to each track shoe, intermediate each pair of adjacent pin and bushing assemblies, for attenuating the noise level of the track assembly upon its engagement with the drive sprocket and for aiding in cleaning the sprocket. Each cushioning lug assembly comprises a resilient cushioning block composed of an elastomeric material, a cap mounted on the cushioning block and offset arcuate bearing flanges and a cleaning flange formed integrally on the cap.
