ABSTRACT:
A track for a tracked vehicle, consisting of a track substrate. Terrain lugs are distributed about the circumference the track substrate on its outer surface. Drive profiles, each consisting of at least one drive lug arranged across the width of the track substrate, are distributed about the circumference of the track substrate on its inner surface. The drive profiles may consist of at least two drive lugs spaced apart across the width of the track substrate. Projections are distributed on the inner surface of the track substrate, arranged so as to engage a wheel in a track system that includes the track. The projections are disposed circumferentially between two drive profiles, and may also be disposed laterally between two drive lugs. The projections have a height such that the noise generated when the track moves in a track system is less than the noise generated when a track without such projections moves in a track system. A noise reduction of at least 6 to 8 dB is achievable. The projections may be from at least 3% to at least 7% of the radius of a wheel in the track system.
