Apparatus for reducing track noise in a track-type vehicle

摘要

Apparatus for reducing the noise made by circulation of an endless drive chain comprising a plurality of substantially identical links about a drive sprocket and idler is disclosed. According to the invention, a substantial portion of the energy present in pivotal movement of adjacent links with respect to each other, which occurs as the links are received on the drive sprocket and idler, is absorbed and returned to the pivotal movement therebetween which occurs when the links leave their engagement with the drive sprocket and idler. Specific embodiments of the invention particularly suited for use in reducing track noise in a track-type vehicle are described.
