This invention generally relates to the configuration of the inner surface of a traction band which increases the protection of the embedded reinforcing elements without reducing the flexibility of the band or increasing the generation of heat. The outer surface of the band generally comprises a plurality traction lugs while the inner surface generally comprises a plurality of drive and/or guide lugs. According to the present invention, each group of traction lugs, drive lugs and guide lugs, which are generally laterally aligned, defines generally non-flexible lug areas and each of these lug areas are separated by flexible and generally lug-less hinge areas. The lug areas, on the inner surface thereof, further comprise projections located between the drive lugs and the guide lugs and along the wheel paths defined therebetween.

1. A track for use on a tracked vehicle, said track being made of polymer and adapted to travel over a sprocket wheel, a plurality of road wheels and an idler wheel, said track having an outer ground engaging surface and an inner wheel engaging surface, said track comprising a plurality of substantially non-flexible lug areas separated by flexible lug-less hinge areas, each of said lug areas comprising, on its outer surface thereof, at least one traction lug, and on its inner surface thereof, at least two drive lugs and at least one guide lug, said at least two drive lugs and said at least one guide lug being laterally spaced and defining two wheel paths, said lug areas having embedded therein reinforcing elements aligned with said drive lugs and said guide lugs, wherein said lug areas comprise projections located in said wheel paths and above said reinforcing elements such that said wheel paths are thicker along said lug areas than along said lug-less hinge areas and such that said lug-less hinge areas are substantially devoid of said projections. 2. A track as claimed in claim 1, wherein one of said two wheel paths is defined between one of said at least two drive lugs and said at least one guide lug, and wherein the other of said two wheel paths is defined between the other of said at least two drive lugs and said at least one guide lug. 3. A track as claimed in claim 2, wherein projections on consecutive lug areas define a gap, and wherein said gap is being between 3% and 6% of a diameter of said road wheels. 4. A track as claimed in claim 1, wherein projections on consecutive lug areas define a gap, and wherein said gap is being between 3% and 6% of a diameter of said road wheels. 5. A track for use on a tracked vehicle, said track being made of polymer and adapted to travel over a sprocket wheel, a plurality of road wheels and an idler wheel, said track having an outer ground engaging surface and an inner wheel engaging surface, said track comprising a plurality of substantially non-flexible lug areas separated by flexible lug-less hinge areas, each of said lug areas comprising, on its outer surface thereof, at least one traction lug, and on its inner surface thereof, two drive lugs and one guide lug laterally spaced to define two wheel paths, said lug areas having embedded therein reinforcing elements aligned with said drive lugs and said guide lugs, wherein said lug areas comprise projections located in said wheel paths and above said reinforcing elements such that said wheel paths are thicker along said lug areas than along said lug-less hinge areas and such that said lug-less hinge areas are substantially devoid of said projections. 6. A track as claimed in claim 5, wherein projections on consecutive lug areas define a gap, and wherein said gap is being between 3% and 6% of a diameter of said road wheels.
