Abstract:
An endless drive track with lateral edges having a flat inner surface having a drive mechanism thereon; an outer surface comprising of a plurality of tread blocks equally spaced transversely along the outer surface of the track, each of the tread blocks is moulded to the outer surface of the track; the tread blocks comprise a solid base extending from the outer surface of the track to a point where the tread blocks have a plurality of slots; the bottom end of the slots in the tread blocks are of equal distance from the outer surface of the track, each of the slots are strategically located in the tread blocks to cause a staggered pattern with an adjacent block; the slots in each of the tread blocks have a shallow depth towards the lateral edges of the tread blocks increasing in depth towards the centre of the tread blocks having the greatest depth towards the longitudinal centre line of the track; each of the slots divides the tread blocks into a plurality of tread sections causing a staggered pattern with an adjacent block; the tread sections increase in height from the lateral edges of the tread blocks to the centre of the tread blocks having the greatest height towards the longitudinal centre line of the track; each of the tread sections has its own radius, the combination of tread sections along the upper portion of each of the tread blocks have a camber-like effect.
