US Patent 7114788 Angled traction lugs for endless band

This invention refers to the traction lugs of reinforced elastomeric endless traction bands, and more particularly to those which are used on heavy vehicles like defense vehicles or for skid steer vehicles. More specifically, the invention relates to traction lugs which are angled with respect to the transversal axis of the traction band and preferably disposed in chevrons, which optimize the band's traction while reducing the occurrences of teeth skipping and the level of vibrations and noise induced by the interaction of the traction band with the sprocket.
