NOISE REDUCING APPARATUS FOR TRACK TYPE VEHICLE DRIVE SPROCKETS AND MEANS FOR ATTACHING SAME Abstract of the Disclosure Apparatus is provided for reducing the noise generated by the meshing of the endless track and drive sprocket of a track type vehicle including a pair of annular treads of resilient material. The treads are mounted about the peripheries of a respective one of a pair of cylindrical wall members provided on opposite sides of the sprocket for positioning the treads in radially aligned relationship with a respective one or the inwardly facing rail surfaces provided on a respective one of the double chains of the track. The treads are sized so that, in a free state, their outer peripheries are positioned radially outwardly of the normal position of their respective rail surfaces when the track is fully seated with the sprocket so that the rail surfaces engage and compress the treads before the track comes into full mesh with the sprocket, thereby alleviating any impact therebetween.
